    797 
    798 	Since the imx driver didn't provide any public control ID definitions,

   1296 	kvm: attach the exit reason of vcpu as auxstr to KVM_RUN output.
   1297 	In KVM, a virtual machine implementation like Qemu can access a vcpu
   1298 	via ioctl.  KVM_RUN is an ioctl command to enter vcpu.  The command
   1299 	returns control for various reasons: needs of device emulation or
   1300 	consuming time slices are the typical ones.  The vmi takes a different
   1301 	action for the reason.
   1302 
   1303 	We, strace users, want to know the reason to understand kvm.  This
   1304 	change prints the reason as auxstr if "-e kvm=vcpu" option is given,
   1305 	and if strace runs on Linux 4.16.0 or higher, which includes commit
   1306 	e46b469278a59781f9b25ff608af84892963821b, "kvm: embed vcpu id to dentry
   1307 	of vcpu anon inode."
   1308 
   1309 	The way to get the reason is a bit complicated because the ioctl does
   1310 	not return it to the userspace directly.  Instead, the vmi and kvm
   1311 	communicate via an area of the process virtual memory where the fd of
   1312 	vcpu is mmap'ed.  strace must peek the area to know the reason.
   1313 
   1314 	The change does three things: (1) recording the area for the given vcpu
   1315 	when the target calls VCPU_CREATE to vcpu_info_list per tcb data field,
   1316 	(2) verifying the data recorded in vcpu_info_list before doing (3), and
   1317 	(3) decoding the exit reason field of the area.
   1318 
   1319 	The change is complicated because there is a case that strace
   1320 	does not have a chance to do (1) if -p option is used.
   1321 	In this case, vcpu_info data created in the step (2).

   1992 
   1993 	nlattr: add value processing support for xlat/flags nlattr decoders.
   1994 	Needed for upcoming decoder of ethernet proto which is stored in the
   1995 	host order and has to be converted to the network order before printing
   1996 	as an xval constant.  This change also adds ability to provide
   1997 	prefix/suffix in order to enclose the printed value in something that
   1998 	describes the performed conversion.

   2016 	As of now, it's impossible to introduce a dispatching nlattr decoder
   2017 	that performs actions based on the type of the message, so let's use
   2018 	a combination of zero decoder list size and non-zero decoder pointer

   3211 	linux/arm/raw_syscall.h: avoid r7 specified register variables with Thumb
   3212 	If Thumb code is being generated and frame pointers are enabled, the
   3213 	Thumb frame pointer in r7 clashes with any local variable which may
   3214 	need to be assigned to r7 (e.g. the syscall NR when making a raw
   3215 	syscall).
   3216 
   3217 	With gcc, the double use of r7 results in a build error, e.g.
   3218 
   3219 	  strace-4.22/tests/inject-nf.c:86:1: error: r7 cannot be used in asm here
   3220 
   3221 	With clang, the double use of r7 can result in the compiler silently
   3222 	generating broken code which crashes at run time due to frame pointer
   3223 	corruption:
   3224 
   3225 	  https://bugs.llvm.org/show_bug.cgi?id=34165
   3226 
   3227 	In most cases the problem isn't visible as frame pointers will be
   3228 	disabled automatically due to optimisation level. However to handle
   3229 	cases where frame pointers are enabled (e.g. when CFLAGS etc are set
   3230 	to support a debug build, etc) provide a version of raw_syscall_0
   3231 	which manually saves and restores the frame pointer value in r7

   3330 	xlat: update MSG_* constants.
   3331 	Sync them with kernel's include/linux/socket.h, since syscalls perform
   3332 	almost no checks for incorrect flags.

   3337 	MSG_WAITFORONE, MSG_FASTOPEN, MSG_CMSG_CLOEXEC): Add default values
   3338 	to all constants.
   3339 	(MSG_SENDPAGE_NOTLAST, MSG_NO_SHARED_FRAGS): New constants.  It is
   3340 	an internal one, but, apparently, nothing prohibits passing it
   3341 	to the kernel.
   3342 	(MSG_CMSG_COMPAT): New constant.  Override the value provided
   3343 	by system headers.
   3344 	(MSG_EOF): Commented out, as it is a synonym for MSG_FIN.

   3651 	As the header with command definitions is now a part of UAPI (since
   3652 	Linux commit v4.16-rc1~21^2~11), there's no need for a very special
   3653 	printing routine for command names.

   4064 	The unwind subsystem uses the mmap_cache subsystem even it uses
   4065 	unwind-libdw as backend. unwind-libdw doesn't need the full set of the
   4066 	mmap_cache subsystem; libdw has a feature for caching a memory
   4067 	mapping.
   4068 
   4069 	This commit does three things.
   4070 
   4071 	(1) Make the unwind subsystem not use the mmap_cache subsystem.
   4072 	The unwind subsystem never concern the memory mapping of the target.
   4073 	It becomes a thin layer.
   4074 
   4075 	(2) Make unwind-libunwind use the mmap_cache subsystem directly.
   4076 
   4077 	(3) Make unwind-libdw use the mmap_notify subsystem to know when it
   4078 	should call dwfl_linux_proc_report/dwfl_report_end for updating the
   4079 	cache.
   4080

   4329 	xlat: override values of KEY_RFKILL and KEY_BRIGHTNESS_MIN constants.
   4330 	KEY_RFKILL and KEY_NUMERIC_A constants were introduced by Linux kernel
   4331 	commits v2.6.33~17^2~2 and v4.1-rc1~150^2~1^10~6, respectively.
   4332 	Apparently, RHEL6 introduced an alternative KEY_RFKILL constant
   4333 	with the same value as upstream KEY_NUMERIC_A.
   4334 
   4335 	KEY_BRIGHTNESS_MIN and KEY_BRIGHTNESS_MAX constants were introduced
   4336 	by Linux kernel commit v3.16-rc1~30^2~6^2~1^2~7.
   4337 	Apparently, RHEL7 introduced an alternative KEY_BRIGHTNESS_MIN constant
   4338 	with the same value as upstream KEY_BRIGHTNESS_MAX.
   4339 
   4340 	Downstream vendors are *not* allowed to do this.
   4341 	Ignore the system value of KEY_RFKILL and KEY_BRIGHTNESS_MIN.
   4342 
   4343 	* xlat/evdev_keycode.in (KEY_RFKILL, KEY_BRIGHTNESS_MIN): Undefine.

   4347 	xlat: override the value of KEY_DATA constant.
   4348 	Linux kernel commit v4.9-rc8~12^2 has changed the value of KEY_DATA
   4349 	constant introduced by commit v4.7-rc6~32^2~6^2 because the old value
   4350 	was already used by KEY_FASTREVERSE.
   4351 
   4352 	Looks like the best way to handle this situation is to pretend that
   4353 	the old value of KEY_DATA didn't exist.

   4358 
   4359 	xlat: override the value of AUDIT_FEATURE_CHANGE constant.
   4360 	Linux kernel commit v3.15-rc1~18^2~1 has changed the value
   4361 	of AUDIT_FEATURE_CHANGE constant introduced by commit v3.13-rc1~19^2~20
   4362 	which is of course an ABI breakage that affected 3.13 and 3.14 kernel
   4363 	releases as well as their LTS derivatives.
   4364 
   4365 	Linux kernel commit v3.15-rc1~18^2~1 also claims that the old value
   4366 	of AUDIT_FEATURE_CHANGE was ignored by userspace because of the
   4367 	established convention how netlink messages for the audit system
   4368 	are divided into blocks.
   4369 
   4370 	Looks like the best way to handle this situation is to pretend that
   4371 	the old value of AUDIT_FEATURE_CHANGE didn't exist.
   4372 
   4373 	* xlat/nl_audit_types.in (AUDIT_FEATURE_CHANGE): Undefine.

   5551 	This change renames functions exported to strace core part from unwind

   5553 
   5554 	The new names imply that unwind subsystem exports two types of

   5556 	is used for this type.  Another is for manipulating back-end private data
   5557 	structure (unwind_ctx) attached to tcb, "unwind_tcb_" is used for this

   5739 	tests: refactor bpf test.
   5740 	The aim of this change is to introduce an ability to perform multiple
   5741 	checks for a specific bpf command.  In order to achieve so, all the
   5742 	related data is stored in check descriptor, and test_bpf iterates over
   5743 	it.  There are also some provisions made in regard to future changes
   5744 	(specifically, the way bpf_attr_data union is defined).
   5745 
   5746 	* tests/bpf.c (print_bpf_attr): New function, a wrapper around
   5747 	struct bpf_check.printer.
   5748 	(test_bpf_): Rename to...

   5750 	Iterate over possible attribute variants. Account for changes in
   5751 	attribute initialisation routine: provide a pointer to locally defined
   5752 	union bpf_attr_data and perform memcpy afterwards. Initialise memory
   5753 	from data each time before a bpf call.
   5754 	(TEST_BPF, DEF_*, init_*, print_*): Remove.

   6536 	build: do not hardcode -lrt.
   6537 	Depending on libc implementation, various -lrt functions can be
   6538 	implemented either in -lc or in -lrt.  For example, starting with
   6539 	glibc-2.17 the clock_* suite of functions is available directly in -lc.
   6540 
   6541 	Check whether clock_* and mq_* suites of functions are provided
   6542 	by -lrt or by the main C library, do not link with -lrt unnecessarily.
   6543 
   6544 	This change affects only tests yet, but this is going to be
   6545 	more important as soon as strace starts using clock_gettime.
   6546 
   6547 	* configure.ac (AC_SEARCH_LIBS): Check for clock_gettime and mq_open
   6548 	in -lrt.
   6549 	(AC_SUBST): Add clock_LIBS and mq_LIBS.

   7423 	unwind: lift up unw_flush_cache from mmap cache management code.
   7424 	For making mmap cache code reusable from other areas in strace
   7425 	than unwind, mmap cache related code and unwind related code

   8372 	We (apparently) had a long-standing test failure inside strace-ff.test
   8373 	with the symptom that it misses exit_group call.  As it turned out, it
   8374 	was PTRACE_EVENT_EXEC followed by execve syscall exiting stop.  That
   8375 	behaviour indeed screwed all the syscall state tracking for the tracee.

   8399 	ia64: do not bail out in get_syscall_args if umove fails with EPERM.
   8400 	If the kernel contains commit 84d77d3f06e7e8dea057d10e8ec77ad71f721be3,
   8401 	both PTRACE_PEEKDATA and process_vm_readv become unavailable when the
   8402 	process dumpable flag is cleared, on ia64 this results to all syscall
   8403 	arguments being unavailable.
   8404 
   8405 	Recognize this situation and do not treat it as get_syscall_args error
   8406 	because the latter leaves the tracee in a ptrace stop.
   8407 
   8408 	This condition used to be triggered by prctl-dumpable test that caused
   8409 	strace to hang indefinitely.

   8557 	mpers: implement gawk 3 support.
   8558 	Some old systems that still make some sense to be supported have only
   8559 	gawk 3, so let's support them for now.
   8560 
   8561 	In order to achieve that, multiple changes have been implemented:
   8562 	 - Multidimensional arrays are replaced with single-dimensional ones.
   8563 	   In most places it's a "][" -> ", " replacement, as awk allows some
   8564 	   kind of emulation of multidimensional arrays that way, but in several
   8565 	   occasions (specifically for storing name and special fields) we have
   8566 	   to iterate over them later, so we store that information in
   8567 	   additional arrays in order to get the keys.
   8568 	 - "switch" statements are replaced with sets of "if ... else if ...
   8569 	   else" statements.  This change is trivial, except we've added
   8570 	   a temporary variable in what_is order to store expression value, for
   8571 	   readability purposes.
   8572 	 - No support for array iteration ordering.  This one is most ugly of
   8573 	   them all.  Luckily, not that ugly, we've just had to process index a
   8574 	   bit in order to make it lexicographically sortable and add two
   8575 	   temporary arrays containing sorted indices in order to sort over them
   8576 	   instead of those two arrays that we've added in order to work around
   8577 	   lack of multidimensional array support.
   8578 
   8579 	* mpers.awk (compare_indices): Remove unused function.
   8580 	(array_get, update_upper_bound, /^DW_AT_data_member_location/,
   8581 	/^DW_AT_byte_size/, /^DW_AT_encoding/): Replace multidimensional array
   8582 	access with comma-concatenated index.
   8583 	(norm_idx): New function.
   8584 	(array_seq): Replace multidimensional array access with
   8585 	comma-concatenated index.  Use comma-concatenated pair of (array_idx,
   8586 	"seq") in order to check presence of the item in an array.
   8587 	(what_is): Add enc and i local variables.  Store the value of
   8588 	array[what_idx, "encoding"] in it.  Replace "switch" statements with
   8589 	sets of "if ... else if ... else" statements.  Replace multidimensional
   8590 	array access with comma-concatenated index. Use for (... ; ...; ...)
   8591 	iteration over aparents_keys instead of iteration over array.
   8592 	(/^<[[:xdigit:]]+>/): Store idx as norm_idx(matches[2]).  Replace
   8593 	multidimensional array access with comma-concatenated index.  Store an
   8594 	additional flag in array_names array.
   8595 	(/^DW_AT_name/): Replace multidimensional array access with
   8596 	comma-concatenated index.  Add a flag to array_names for that idx.
   8597 	(/^DW_AT_type/): Do not capture "0x" as a part of a group, normalise
   8598 	the captured group.  Replace multidimensional array access with
   8599 	comma-concatenated index.
   8600 	(/^Abbrev Number:[^(]+\(DW_TAG_/): Replace multidimensional array access
   8601 	with comma-concatenated index.  Store additional flags in
   8602 	array_special and array_parents arrays.
   8603 	(END): Remove PROCINFO["sorted_in"] setup.  Sort array_parents.  Replace
   8604 	multidimensional array access with comma-concatenated index.  Iterate
   8605 	over array_special to go over all the items that have "special" field.
   8606 	Iterate over array_names to go over all items that have "name" field.
   8607 	* NEWS: Mention it.

   8612 	Commit v4.13-rc1~137^2~13 (and a follow-up fix v4.14-rc4~20^2~3
   8613 	that changed alignment) introduced an additional hidden field
   8614 	in the structure returned by DM_LIST_DEVICES ioctl command

   8940 
   8941 	Fix pathtrace for old_mmap/old_mmap_pgoff.
   8942 	As these system calls have only one argument that points to the

   9030 	syscall.c: add ability to set personality based on GETREGSET iov size.
   9031 	Some architectures (aarch64, s390x) use only PTRACE_GETREGSET interface
   9032 	and use its size to detect current personality. Let's generalise this

   9034 	update personality, at least for those architectures.
   9035 
   9036 	Note that in order to employ this behaviour, architecture has to use
   9037 	PTRACE_GETREGSET exclusively (no HAVE_GETREGS_OLD) and should declare

   9058 	move the check whether we are setting the same personality as we
   9059 	currently are inside set_personality out of update_personality.

   9070 	syscall.c: always update tcp->currpers in update_personality.
   9071 	Sometimes (for example, switching from a process with one personality
   9072 	to a process that previously had different personality but returning
   9073 	from execve to that same personality into) it is possible that
   9074 	current_personality is not changed, but tcp->currpers is different.
   9075 	So, let's not return from update_personality and always update
   9076 	tcp->currpers if it differs from the target personality.
   9077 
   9078 	* syscall.c (update_personality): Do not exit early if personality ==

   9427 	tests: check decoding of modify_ldt with for 4-byte-available user_desc.
   9428 	Since there is possibility now that strace read only entry_number field
   9429 	of the user_desc struct, let's check that it doesn't do it with
   9430 	modify_ldt syscall.
   9431 
   9432 	* tests/modify_ldt.c (main): Add 4-byte-sized tail_alloc'ed variable.

   9436 
   9437 	Allow separate printing of struct user_desc.entry_number.
   9438 	Kernel reads only entry_number field in the beginning of the

   9477 2018-01-08  Eugene Syromyatnikov  <evgsyr (a] gmail.com>
   9478 
   9479 	syscall.c: add support for printing return value and error code.
   9480 	Some weird syscalls (like modify_ldt) return value that doesn't indicate
   9481 	an error (less than -4096), but it is, in fact, erroneous (because they
   9482 	decide to clip the return value to 32-bit, for example).
   9483 
   9484 	Add a flag to print decoded error code along with syscall return value.

   9500 
   9501 	ldt.c: make struct user_desc output more structured.
   9502 	Also, while we are here, let's fix print qualifiers (which should be %u
   9503 	and not %d).
   9504 
   9505 	* ldt.c (print_user_desc): Use PRINT_FIELD_* macros for printing
   9506 	structure.
   9507 	(SYS_FUNC(set_thread_area)): Change field key-value separator from ":"

   9512 	print_fields.h: add PRINT_FIELD_U_CAST.
   9513 	Add a macro for printing fields explicitly casted to specific type.
   9514 	This is useful for bit fields, as otherwise the magic of *_extend_to_*
   9515 	macros breaks.
   9516 
   9517 	* print_field.h (PRINT_FIELD_U_CAST): New macro.
   9518 
   9519 2018-01-08  Eugene Syromyatnikov  <evgsyr (a] gmail.com>
   9520 
   9521 	print_fields.h: rename PRINT_FIELD_UID to PRINT_FIELD_ID.
   9522 	As uid is not the only thing that has a special treatment of the -1
   9523 	value (and, as a result, needs special care), let's rename
   9524 	PRINT_FIELD_UID to PRINT_FIELD_ID and make PRINT_FIELD_UID its alias.
   9525 
   9526 	* print_fields.h (PRINT_FIELD_ID): Rename from PRINT_FIELD_UID.

   10928 	xlat/gen.sh: speedup xlat generation.
   10929 	This commit implements the following changes:
   10930 	- increases the number of concurrent jobs to twice the CPU count;
   10931 	- creates a circular buffer, so instead of running multiple jobs
   10932 	  at once, the generator tries to keep about the same number of jobs
   10933 	  being run concurrently;
   10934 	- runs gen_git and gen_make concurrently in order to squeeze in
   10935 	  one more bit of concurrency.
   10936 
   10937 	With my deeply scientific measurements, this approach achieves
   10938 	up to 15% speedup with dash and about 30-40% with bash as /bin/sh
   10939 	on a 4-core machine.
   10940 
   10941 	* xlat/gen.sh (main): Declare pids local variable, append pid of every
   10942 	run job to it; increase the limit of jobs to ncpus * 2; when the limit
   10943 	is reached, wait for the first pid in pids instead of resetting jobs
   10944 	to zero and waiting for all the run jobs; put gen_git and gen_make
   10945 	into background.

   12400 	tests: fix sigaction.test on sparc.
   12401 	On sparc, the first argument of old sigaction syscall has negated
   12402 	semantics, compared to other architectures.  While sigaction.test
   12403 	was aware about this arch-specific detail from the beginning, in one
   12404 	of many sigaction syscall invocations a non-negative signal number
   12405 	was erroneously passed on sparc.

   12407 	* tests/sigaction.c (ADDR_INT, SIGNO_INT): New arch-specific macros.

   15326 	dyxlat: new interface for building xlat tables dynamically.
   15327 	xlat tables are usually generated at build time.
   15328 
   15329 	printxval is suitable for printing struct nlmsghdr.nlmsg_type for

   16334 	On some architectures old sigsuspend syscall takes the signal mask from
   16335 	the 3rd argument, on some from the 1st.  And, if it wasn't peculiar
   16336 	enough, the signal mask is passed by value on all architectures except
   16337 	mips where it's passed by reference.
   16338

   16340 	argument.

   21938 	x32 syscalls starting with number 512 are compat syscalls that operate
   21939 	on compat types.  Set COMPAT_SYSCALL_TYPES flag to these syscall entries
   21940 	and make get_syscall_args truncate arguments of syscalls that have this
   21941 	flag set, to avoid unpleasant alternative of adding multiple

   21943 
   21944 	preadv, pwritev, preadv2, and pwritev2 are exceptions: while these

   22426 	Commit dc427d50d96b15c9a64d7e78d97ce4d194622a63 enabled a number of extra
   22427 	warning flags through configure.ac.  The configure script will determine
   22428 	dynamically if CC supports these flags before adding them to WARN_CFLAGS.
   22429 
   22430 	ioctlsort is compiled with CC_FOR_BUILD, rather than CC.  Nevertheless,
   22431 	the flags passed to this compilation also include WARN_CFLAGS (through
   22432 	AM_CFLAGS).  This is incorrect: in a cross-compilation use case, CC
   22433 	and CC_FOR_BUILD are not the same.  The former is the cross-compiler,
   22434 	the latter is the host compiler.  Both may be of different versions
   22435 	and support different warning flags.
   22436 
   22437 	In particular, this posed a problem when cross-compiling with a host
   22438 	compiler gcc 4.1, which does not support all the new flags:

   23057 	When syscalls fail for any reason they may generate syscall-exit-stops.
   23058 
   23059 	The solution is to wait for an actual exit reported by PTRACE_EVENT_EXIT

   23586 	The incomplete CRIS support introduced by commit v4.5.18-77-gea0e6e8
   23587 	should not have been merged because it lacks essential parts, e.g.
   23588 	syscall tables.

   24132 
   24133 	util: add support for QUOTE_0_TERMINATED in user_style to ptrintstr_ex.
   24134 	This enables printing size-limited (expectedly) ASCIZ strings.
   24135 
   24136 	This is done by increasing umoven size limit for sized strings by one
   24137 	byte above max_strlen (enabling copying possible NUL byte in case len is
   24138 	greater than max_strlen) and decreasing size after copying by one byte
   24139 	in case QUOTE_0_TERMINATED is set (due to user_style or usage of len of
   24140 	-1).  As a result, there is one excess byte for string_quote in case
   24141 	QUOTE_0_TERMINATED is set so string_quote can check for NUL termination
   24142 	of strings up to size bytes in size (which is len or max_strlen, whatever
   24143 	is greater).
   24144 
   24145 	The catch here is that when string is not properly NUL-terminated and
   24146 	QUOTE_0_TERMINATED is provided in user_style and len is less than
   24147 	max_strlen then last non-NUL byte is not printed.  But ellipsis is
   24148 	printed instead, being indication that string is not terminated
   24149 	properly.  QUOTE_OMIT_TRAILING_0 should be used instead in case this

   24614 
   24615 	io: use umoven_or_printaddr_ignore_syserror as umove function in tprint_iov_upto
   24616 	This enables printing of iovec arrays even in case of failed syscall
   24617 	(failed syscall doesn't mean that iovec itself is inaccessible and
   24618 	useless).  One caveat here is that we should explicitly provide proper
   24619 	IOV_DECODE_* value based on syserror value in case printing is performed
   24620 	on exiting; we can't simply override it to IOV_DECODE_ADDR on exiting
   24621 	when syserror is up, since this may be called by code which tries to
   24622 	print iovec containing local data, which should be perfectly accessible
   24623 	(on the other hand, there are no cases of such behaviour at the moment).
   24624 
   24625 	Since iovecs themselves are printed even if syscall has failed now,

   24843 
   24844 	util: add quote_string flag signalising that string is NUL-terminated.
   24845 	It is useful in cases strings with size provided are expected to be
   24846 	NUL-terminated but are not trustworthy enough to call just plain

   24871 	* syscall.c (trace_syscall_exiting): Use err_name() instead
   24872 	of open-coding it.  Print unrecognized errno values using %lu format
   24873 	instead of ERRNO_%lu as the latter prodices an invalid constant.

   24909 
   24910 	keyctl: do not print comma for KEYCTL_SESSION_TO_PARENT command.
   24911 	Since this command doesn't have any additional arguments, the comma does
   24912 	not needed.  Since this is the only command which lacks additional
   24913 	arguments, it's better to add special case for it rather than add
   24914 	printing of comma to all other commands.
   24915 
   24916 	* keyctl.c (SYS_FUNC(keyctl)): Add check for command not being

   24928 2016-10-02  Eugene Syromyatnikov  <evgsyr (a] gmail.com>
   24929 
   24930 	keyctl: use printuid for printing UID/GID.
   24931 	UID/GID are unsigned except special -1 value (which is also special in
   24932 	context of specific keyctl commands), so special printing function
   24933 	should be used.
   24934 
   24935 	* keyctl.c (keyctl_chown_key, keyctl_get_persistent): Use printuid
   24936 	instead of printf with "%d" conversion for printing UID/GID.

   24938 2016-10-02  Eugene Syromyatnikov  <evgsyr (a] gmail.com>
   24939 
   24940 	io: handle data_size of -1 as unlimited data in print_iovec.
   24941 	Otherwise it can be depleted and print_iovec starts printing empty
   24942 	strings.
   24943

   24956 	Enhance -e abbrev=set, -e raw=set, and -e verbose=set.
   24957 	Enhance abbrev=, raw=, and verbose= to accept the same syntax as trace=.
   24958 	For example, this allows such syntax as -e verbose=file.
   24959

   24993 	fadvise_64_64 decoder used before this change prints different sign
   24994 	of the "len" argument (loff_t vs size_t).
   24995 
   24996 	* linux/x32/syscallent.h (fadvise64): Replace SEN(fadvise64_64)

   25000 
   25001 	fadvise: use getarg_ull for obtaining len argument of fadvise64 syscall.
   25002 	Since its type is size_t, it is 64-bit wide on x32 and special care

   25023 
   25024 	* fadvise.c (SYS_FUNC(fadvise64)): Change conversion specifier from

   25049 
   25050 	fallocate: change print format of offset and len arguments to signed.
   25051 	Since types of these arguments are off_t and kernel actually expects

   25053 	lets display these values as signed.

   29133 	We used to declare and define all printers marked with
   29134 	MPERS_PRINTER_DECL, including ifdef'ed ones.  That approach left us
   29135 	no way to conditionally compile mpersified printers, which was not

   29137 
   29138 	With this change, those mpersified printers that are not going
   29139 	to be compiled are also won't be declared and won't be added to
   29140 	struct_printers.
   29141 
   29142 	This is implemented by filtering all source files containing
   29143 	MPERS_PRINTER_DECL markers through CPP.  As a nice side effect, this
   29144 	also lifts an ugly requirement of writing all MPERS_PRINTER_DECL

   32687 	* strace.c (init): If fcntl(F_GETFD) fails on stdin or stdout,

   32693 	Close stdin/out after child is forked.
   32694 	Testcase:
   32695 
   32696 	{ sleep 1; yes | head -n99999; } | strace -o/dev/null sh -c 'exec <&-; sleep 9'
   32697 
   32698 	The writer (head) will be able to perform writes to write end of the pipe.
   32699 	With strace call removed, head will immediately get SIGPIPE.
   32700 
   32701 	This change fixes this: now writer immediately gets SIGPIPE with strace too.
   32702 
   32703 	* strace.c (startup_child): Close stdin/out and reopen them to /dev/null.

   32717 	* strace-graph: Prefix each command with its pid.
   32718 
   32719 	strace-graph: cope with clone immediately followed by exit.
   32720 	* strace-graph: A clone() followed by exit() with no intervening fork
   32721 	or execve resulted in the new pid having no seq key.  That breaks when
   32722 	trying to use seq as an array reference.  Ensure that clone populates
   32723 	the new pid with an empty seq entry.
   32724 
   32725 	strace-graph: handle recent strace output.

   32803 
   32804 	Implement caching of print_sockaddr_by_inode.
   32805 	As -yy parser, compared to -y, needs to do at least 5 extra syscalls
   32806 	(getxattr, socket, sendmsg, recvmsg, close) to print socket details,
   32807 	caching results of netlink conversations between strace and kernel
   32808 	noticeably reduces amount of system time spent by strace.
   32809 
   32810 	The caching is safe since sockets do not change their addresses after

   33105 	s390, s390x: fix printing of syscalls unknown to the kernel.
   33106 	On s390/s390x, syscalls with NR up to 255 can be implemented
   33107 	directly using "svc NR", for NR >= 256 "svc 0" with %r1=NR is used.

   33109 
   33110 	When the syscall number specified directly or indirectly is recognized
   33111 	by the kernel, i.e. it is less than its NR_syscalls value, it is stored
   33112 	in %r2 and is available to arch_get_scno via s390_regset.gprs[2].
   33113 	For syscall numbers >= NR_syscalls this register is set to 0,
   33114 	but %r1 remains unchanged and could be used by arch_get_scno
   33115 	via s390_regset.gprs[1] to decide what the syscall number is.
   33116

   34085 
   34086 	Add copyright headers to some files which lack them.
   34087 	Before this change, all files that exist since 20th century had
   34088 	copyright headers, while most files that appeared later didn't.  This
   34089 	change fixes the inconsistency by adding missing copyright headers.
   34090 
   34091 	It doesn't mean that copyright headers became maintained.  In my view,
   34092 	git history provides much better information on this subject and is much
   34093 	more accurate than copyright headers.

   34111 
   34112 	Replace %Ld/%Lu printf format specifiers with %lld/%llu.

   34134 
   34135 	Fix SYS_FUNC and SEN macros for musl.
   34136 	The syscall_name argument was subject to macro expansion because
   34137 	it was passed down to other macros before it was prefixed.
   34138 
   34139 	musl libc defines lfs64 names as macros (e.g. fstat64 as fstat)
   34140 	so SYS_FUNC(fstat64) was expanded to sys_fstat.
   34141 
   34142 	This change adds the prefix before the name is passed to other macros,
   34143 	i.e. the argument of SYS_FUNC_NAME is already prefixed with sys_.
   34144 
   34145 	* defs.h (SYS_FUNC): Add sys_ prefix to SYS_FUNC_NAME's argument.
   34146 	(SYS_FUNC_NAME): Do not add sys_ prefix to MPERS_FUNC_NAME's argument.
   34147 	* linux/ia64/syscallent.h (SYS_FUNC_NAME): Do not add sys_ prefix
   34148 	to MPERS_FUNC_NAME's argument.
   34149 	* syscall.c (SEN_NAME): Remove.
   34150 	(SEN): Replace SEN_NAME call with its definition.  Add sys_ prefix
   34151 	to SYS_FUNC_NAME's argument.

   34154 
   34155 	tests/times.test: workaround libc bug on x32.
   34156 	As glibc times wrapper on x32 is known to wrongly truncate and then sign
   34157 	extend the syscall return value, invoke the syscall directly on x32.
   34158 
   34159 	* tests/times.c (main) [__NR_times && __x86_64__ && __ILP32__]:

   34167 	* mpers_test.sh: Use a more complicated sample type to test mpers
   34168 	machinery.

   34170 2015-12-15  Dmitry V. Levin  <ldv (a] altlinux.org>
   34171 
   34172 	Robustify mpers.awk against input containing index loops.
   34173 	Make mpers.awk check for potential index loops.  Such loops should not
   34174 	normally happen, but mpers.awk will not go into infinite recursion if
   34175 	they do.
   34176 
   34177 	* mpers.awk (enter, leave): New functions.
   34178 	(what_is): Use them.
   34179 
   34180 2015-12-15  Dmitry V. Levin  <ldv (a] altlinux.org>
   34181 
   34182 	Robustify mpers.awk against invalid input.
   34183 	Make mpers.awk check that accessed elements of the main array that
   34184 	are expected to have non-empty values really meet this requirement.
   34185 
   34186 	* mpers.awk (array_get): New function.
   34187 	(what_is, END): Use it.

   34200 
   34201 	Remove unused parser of xmknod syscall.

   34208 
   34209 	tests/restart_syscall: add a workaround for old arm kernels.
   34210 	As arm kernels used to overwrite ARM_r0 with -EINTR after
   34211 	ERESTART_RESTARTBLOCK, update regexp to workaround this.
   34212 
   34213 	* tests/restart_syscall.c (main) [__arm__]: Add 0xfffffffc as a valid
   34214 	alternative value for the first argument of restarted nanosleep syscall.
   34215 
   34216 2015-12-12  Dmitry V. Levin  <ldv (a] altlinux.org>
   34217 
   34218 	tests/.gitignore: add ksysent.h.

   34226 	aarch64: make arm registers unsigned.
   34227 	Follow the x86_64 example and define registers in arm_pt_regs
   34228 	as unsigned, to avoid potential sign extension bugs.
   34229 
   34230 	This also fixes --enable-gcc-Werror build.
   34231 
   34232 	* linux/aarch64/arch_regs.c (arm_pt_regs): Change uregs's type

   34238 
   34239 	tests: add ksysent.test.
   34240 	Check that syscall names and numbers defined in syscallent files
   34241 	match kernel __NR_* constants defined by <asm/unistd.h>.
   34242 
   34243 	Tested on various platforms, including the following combinations
   34244 	of architectures and kernel headers:
   34245 
   34246 	x86_64: 4.4-rc, 4.3, 4.2, 4.1, 3.19, 3.17, 3.16, 3.12, 3.11,
   34247 	3.10-rhel, 2.6.32-rhel, 2.6.27-sle, 2.6.18-rhel
   34248 	i386: 4.4-rc, 4.3, 4.2, 4.1, 3.19, 3.17, 3.16, 3.11,
   34249 	3.10-rhel, 2.6.32-rhel, 2.6.27-sle, 2.6.18-rhel
   34250 	aarch64: 4.4-rc
   34251 	alpha: 4.3
   34252 	arm eabi: 4.4-rc, 4.2, 4.1

   34254 	ia64: 3.18
   34255 	mips o32: 4.1
   34256 	ppc: 3.18
   34257 	ppc64: 3.10-rhel, 2.6.32-rhel
   34258 	s390: 3.18

   34260 	sparc: 4.1
   34261 	sparc: 3.18
   34262 	x32: 3.19
   34263 
   34264 	The only platform which is known at this moment to fail the test
   34265 	is CentOS-5 provided by OBS.  On x86_64 instance it fails with
   34266 	error: "prlimit64" syscall #300 is "fanotify_init" in syscallent.h
   34267 	and on i586 it similarly fails with
   34268 	error: "prlimit64" syscall #338 is "fanotify_init" in syscallent.h
   34269 	So this is a real platform bug that is not likely to be worked around
   34270 	on the strace side.

   34272 	* tests/ksysent.c: New file.
   34273 	* tests/ksysent.sed: Likewise.

   34290 
   34291 	ia64: print all ia32 syscalls using printargs.
   34292 	Printing of ia32 syscalls on ia64 must have been broken for a long time.
   34293 	Do not pretend that it works, print ia32 syscalls using printargs
   34294 	instead.
   34295 
   34296 	* linux/ia64/syscallent.h: Remove all redefinitions of sys_* macros.

   34711 	is done by custom code.  Specifying IOCTL_NUMBER_STOP_LOOKUP on

   36469 
   36470 	Add mpers support.
   36471 	Add a subsystem for semi-automatical definition of how parsers should
   36472 	work with personality-dependent (mpers) types of tracee's data.  Create
   36473 	auxiliary libraries containing mpers syscall parsers and printer
   36474 	functions, one library for each possible nonnative target personality.
   36475 
   36476 	Currently some parsers do not handle differences in definitions of data
   36477 	types between personalities, namely LP64 and ILP32.  When
   36478 	this is the case, long integers, pointers, and all compound
   36479 	types containing long and pointer members may be printed incorrectly,
   36480 	because of differences in sizes, offsets and alignments.
   36481 
   36482 	Since in most cases these are the only differences in desired behaviour
   36483 	of parsers and printers for different personalities, a correct way
   36484 	would be to compile one source code into multiple parsers, differing
   36485 	only in definitions of mpers types.
   36486 
   36487 	To get a definition of a given type for nonnative personality
   36488 	a very basic .c file containing a declaration of a variable of this type
   36489 	is being compiled for this personality (using -m32 or -mx32 compiler
   36490 	flag).  Information about the type is then being extracted from
   36491 	this binary's DWARF debug info with an awk script and put
   36492 	into a corresponding header file.  Resulting headers are being used to
   36493 	compile mpers variations of syscall parsers and printer functions.
   36494 
   36495 	In addition to syscall parsers, there can occur a need to create mpers
   36496 	printing functions, which then can be called from many places
   36497 	in the code (for example, printsiginfo_at).  Such functions (printers)
   36498 	are marked in a special manner.
   36499 
   36500 	For each possible nonnative target personality a library is being
   36501 	created, containing mpers variations of syscall parsers and printers.
   36502 	Only syscall parsers from files marked in a special manner and specially
   36503 	marked functions from such files are being recompiled and included
   36504 	in these libraries.
   36505 
   36506 	generate_mpers_am.sh is called by bootstrap to find the files
   36507 	from strace_SOURCES which include MPERS_DEFS.  During compilation,
   36508 	these files are being inspected for inclusions of DEF_MPERS_TYPE,
   36509 	and nonnative variations of each included type are being generated
   36510 	by an awk script.
   36511 
   36512 	Mpers parser names are being modified during inclusions of syscallent
   36513 	headers for nonnative personalities.  Pointers to printers are
   36514 	being stored in structs struct_printers, and a master
   36515 	pointer printers is being updated on every set_personality.

   36675 	decode extend getsockopt/setsockopt options.
   36676 	Currently the code assumes the set of valid options between getsockopt
   36677 	and setsockopt are exactly the same and thus maintains one list.  The
   36678 	kernel unfortunately does not do this -- it allows for different opts
   36679 	between the get and set functions.  See the {g,s}et_opt{min,max} fields
   36680 	in the various netfilter subcores.
   36681 
   36682 	To support this, extend the printxval function to take multiple sets of
   36683 	xlats as varargs.  Then we add the new get/set lists, and pass them down
   36684 	in the net code when decoding things.
   36685

   38703 	sparc: delete personality 1.
   38704 	Personality 1 for sparc and sparc64 appears to be an old attempt
   38705 	to support stracing Solaris binaries.
   38706 
   38707 	It stalled after the only syscall, solaris_open, was covered:
   38708 	all other solaris_foo's are printargs.
   38709 
   38710 	This change deletes personality 1. Now sparc is an one-personality
   38711 	arch, and sparc64 is a two-personality one.
   38712 
   38713 	For clarity, pure renaming of personality 2 files to personality 1 for sparc64
   38714 	is performed in the next commit - this prevents a state where syscallent1.h
   38715 	seems to indergo a lot of changes, where in fact in is deleted, and then
   38716 	replaced by syscallent2.h
   38717 
   38718 	Therefore, tree at this commit will not build.

   38877 
   38878 	Show the syscall name in "resuming interrupted call" message.
   38879 	When signal is received, or if we have attached to a process,
   38880 	current syscall (if process is in one) gets restarted.
   38881 
   38882 	Some syscalls are restarted via "restart_syscall()" mechanism.
   38883 	On such sycalls, we don't show _which_ syscall gets restarted.
   38884 
   38885 	IOW: users want to see "resuming interrupted nanosleep"
   38886 	instead of "resuming interrupted call" when they attach to "sleep 999".
   38887 
   38888 	Kernel does expose this information. The only thing we need is
   38889 	to fetch syscall# on attach, and save it.
   38890 
   38891 	This patch does this. It adds tcp->s_prev_ent, which is
   38892 	a pointer to struct_sysent of the previous syscall of this tracee.
   38893 	It can be NULL.
   38894 
   38895 	sys_restart_syscall() is made to use it when the message is generated.
   38896 
   38897 	To similarly handle restart_syscall() *after signals*, not just
   38898 	on attach, on each syscall exit patch saves exited syscall's data
   38899 	in the same member (tcp->s_prev_ent).
   38900 
   38901 	Example:
   38902

   38905 	    restart_syscall(<... resuming interrupted nanosleep ...>) = 0

   40660 
   40661 2015-01-22  Dmitry V. Levin  <ldv (a] altlinux.org>
   40662 
   40663 	ioctl: take all 32 bits of ioctl commands into account.
   40664 	Historically, only 16 bits (8-bit number and 8-bit type) of 32-bit ioctl
   40665 	commands were used for decoding, which was the source for numerous
   40666 	annoying collisions like this:
   40667 
   40668 		ioctl(0, SNDCTL_TMR_TIMEBASE or SNDRV_TIMER_IOCTL_NEXT_DEVICE or TCGETS, {B38400 opost isig icanon echo ...}) = 0
   40669 		ioctl(0, MGSL_IOCGPARAMS or MMTIMER_GETRES or MTIOCTOP or SNDCTL_MIDI_MPUMODE, 0x7fffd47f7338) = -1 ENOTTY (Inappropriate ioctl for device)
   40670 
   40671 	The solution is to use all 32 bits for decoding, not just "number" and
   40672 	"type", but also "size" and "direction".
   40673 
   40674 	As some architectures override defaults that come from asm-generic/ and
   40675 	provide alternative definitions for some ioctl commands, we support
   40676 	per-architecture ioctl definitions and merge them with common
   40677 	definitions at build time.  During the merge, we used to keep both
   40678 	generic and architecture-specific definitions, now architecture-specific
   40679 	definitions have precedence over generic ones -- ioctlsort omits
   40680 	definitions from asm-generic/ for those ioctl names that have different
   40681 	definitions in asm/.
   40682 
   40683 	Additional bits of "direction" are architecture specific -- the number
   40684 	of bits and their values differ between architectures.  To reduce
   40685 	architecture differences in the source code, we keep "direction" in
   40686 	symbolic form and compile it in ioctlsort.
   40687 
   40688 	Additional bits of "size" are also architecture specific -- not only the
   40689 	number of bits differ between architectures, but sizes of many types
   40690 	depend on sizeof(long).  To reduce architecture differences in the
   40691 	source code, we keep 32-bit and 64-bit versions of common ioctl
   40692 	definitions, and use the appropriate version for each architecture and
   40693 	personality.
   40694 
   40695 	To implement this, the tools for generating ioctl definitions from
   40696 	kernel headers have been rewritten, and the source format of ioctl
   40697 	definitions has been extended.   The final ioctlent*.h files that are
   40698 	included by syscall.c are now generated from source ioctls_inc*.h and
   40699 	ioctls_arch*.h files at build time with ioctlsort.

   41672 	Support unix domain sockets in -yy option.
   41673 	This change extends -yy option to handle unix domain sockets:
   41674 	their peer addresses will be printed, similar to inet sockets.
   41675 
   41676 	For a listening socket, its socket inode and socket path are printed.
   41677 	For an accepted socket, its socket inode, the peer inode, and the
   41678 	socket path are printed.
   41679 	For a client socket, its socket inode and the peer inode are printed.
   41680 
   41681 	An example of a server side communication using netcat:
   41682 
   41683 		$ ./strace -yy -e network nc -l -U /tmp/example.sock
   41684 		socket(PF_LOCAL, SOCK_STREAM, 0)        = 3
   41685 		setsockopt(3<UNIX:[14728348]>, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
   41686 		bind(3<UNIX:[14728348]>, {sa_family=AF_LOCAL, sun_path="/tmp/example.sock"}, 19) = 0
   41687 		listen(3<UNIX:[14728348,"/tmp/example.sock"]>, 10) = 0
   41688 		accept(3<UNIX:[14728348,"/tmp/example.sock"]>, {sa_family=AF_LOCAL, NULL}, [2]) = 4<UNIX:[14727246->14727245,"/tmp/example.sock"]>

   41706 	(receive_responses): Add a new argument named parser: a function for
   41707 	handling protocol specific data parts of diag messages.
   41708 	(print_sockaddr_by_inode): Call unix_print.
   41709 	Replace NETLINK_INET_DIAG with NETLINK_SOCK_DIAG, they are equal
   41710 	but NETLINK_SOCK_DIAG looks more generic.

   41712 2014-12-16  Masatake YAMATO  <yamato (a] redhat.com>
   41713 
   41714 	Use the protocol name of a socket as a hint for peer address resolution.
   41715 	To resolve the peer address of socket, all combinations of families
   41716 	(AF_INET, AF_INET6) and protocols(IPPROTO_TCP, IPPROTO_UDP) were tried.
   41717 	This change utilizes the protocol name obtained via getxattr to specify
   41718 	the right combination.
   41719 
   41720 	* socketutils.c (inet_print): New helper function.
   41721 	(print_sockaddr_by_inode): Use it.  Utilize the protocol name
   41722 	associated with the given inode for resolving the peer socket
   41723 	address.  If the protocol name is NULL, resolve the address
   41724 	by trying combinations of families and protocols as before.
   41725 	* defs.h (print_sockaddr_by_inode): Update prototype.
   41726 	* util.c (printfd): Pass the protocol name associated with
   41727 	the given path to print_sockaddr_by_inode as the 2nd argument.

   41729 2014-12-16  Dmitry V. Levin  <ldv (a] altlinux.org>
   41730 
   41731 	Fix decoding of getgroups, getgroups32, setgroups, and setgroups32 syscalls
   41732 	Convert parsers of these syscalls to the same scheme as were applied to
   41733 	parsers of other uid/gid related syscalls.
   41734 	That is, define two sets of parsers on architectures that support
   41735 	(either directly or via multiarch) 16-bit and 32-bit gid getgroups
   41736 	and setgroups syscalls simultaneously, and reuse essentially the same
   41737 	code by parametrizing uid_t and names of parser functions.
   41738 
   41739 	* groups.c: Remove.
   41740 	(sys_getgroups, sys_setgroups): Move ...

   41762 
   41763 	Fix decoding of 16-bit *chown and [gs]et*[gu]id syscalls.
   41764 	Define two sets of parsers on architectures that support (either
   41765 	directly or via multiarch) 16-bit and 32-bit uid/gid syscalls
   41766 	simultaneously.  Since the code in these two sets is essentially
   41767 	the same and the key difference between them is the size of uid_t,
   41768 	implement it by parametrizing uid_t and names of parser functions.
   41769 
   41770 	* defs.h (NEED_UID16_PARSERS): New macro.
   41771 	* linux/syscall.h [NEED_UID16_PARSERS] (sys_chown16, sys_fchown16,

   41844 
   41845 	printuid: fix uid_t decoding on 64-bit architectures.
   41846 	It was not a good idea to treat uid_t as a long int type because

   41884 2014-12-11  Dmitry V. Levin  <ldv (a] altlinux.org>
   41885 
   41886 	Always compile sys_prctl parser.
   41887 	Since sys_prctl is referenced by syscallent files unconditionally,
   41888 	conditional compilation of sys_prctl depending on prctl availability is
   41889 	pointless.
   41890

   42336 	For those socket descriptors that have no associated ip:port pairs
   42337 	(or when this information is not available), -yy option prints

   42402 	hppa: update error codes and signal numbers.
   42403 	There are two important changes in here:
   42404 
   42405 	1. EWOULDBLOCK has been up to kernel 3.14 errorcode #246. Since hppa
   42406 	folks had problems with EWOULDBLOCK != EAGAIN, this was changed in
   42407 	kernel 3.14.
   42408 
   42409 	2. Starting with kernel 3.18, hppa folks changed some signal numbers in
   42410 	such a way that we end up with SIGRTMIN == 32, which brings hppa in sync
   42411 	with other linux ports.
   42412 
   42413 	Both were incompatible changes which basically broke hppa ABI, but since
   42414 	they have been merged into the kernel, we have to follow.

   42417 
   42418 	stack trace support: fix check on symbol name presence.
   42419 	The output format of the stack trace is supposed to be different
   42420 	depending on whether symbol names are available in the build.
   42421 
   42422 	However, the check only verified the validity of the pointer, not of the
   42423 	string pointed to (which could be empty).
   42424 
   42425 	This commit fixes the check so that the original output:

   42492

   42531 	While most of ioctl-related kernel headers are now exported by kernel's

   42533 	headers installed into /usr/include/ are usually headers_install'ed and
   42534 	therefore don't contain some internal headers we need.  The solution is

   42971 	ia64: add missing syscalls.
   42972 	When the preadv/pwritev syscalls were added, the ones before it in the
   42973 	ia64 list were missed, so all the syscalls there and later were not in
   42974 	the right location (causing things to be decoded incorrectly).
   42975 
   42976 	Add the missing syscalls before preadv which also re-aligns all the

   43038 
   43039 	The problem is that while `set -e` is disabled for the body of the
   43040 	cleanup function, it isn't necessarily disabled in the caller scope.
   43041 	So if the return value of the cleanup function (`wait` in this case)
   43042 	is non-zero, the script ends up failing overall.
   43043

   43338 	unwind: move stacktrace capturing and mmap cache invalidating to trace_syscall_entering
   43339 	Instead of handling stacktrace capturing and mmap cache invalidating in
   43340 	sys_* functions, handle them uniformly in trace_syscall_entering using
   43341 	new flags introduced by previous two commits.
   43342 
   43343 	The patch is simpler than its older version(v3).  The value of
   43344 	hide_log_until_execve is just ignored.  I found the value is nothing
   43345 	to do with this patch.  unwind_cache_invalidate is mentioned only
   43346 	once in trace_syscall_exiting.
   43347 	Both are suggested by Dmitry Levin.

   43352 	Add SE flag to execve, exit, and exit_group syscall entries.

   43357 
   43358 	unwind: introduce markers specifying the needs of special care in unwinding
   43359 	Some system calls require capturing the stack trace before they are
   43360 	processed in kernel.  Typical one is execve.  Some system calls require
   43361 	invalidating mmap cache after they are processed in kernel.
   43362 
   43363 	In current implementation these requirements are handled directly by
   43364 	appropriate syscall handlers.  However, it is difficult to keep the
   43365 	source code maintainable using this approach to cover all system calls
   43366 	which have such requirements.
   43367 
   43368 	A more generic way to implement this is to flag all syscalls that
   43369 	require special processing, and handle these flags right in
   43370 	trace_syscall_entering instead of changing syscall handlers.
   43371 
   43372 	This patch just defines new flags: STACKTRACE_INVALIDATE_CACHE and
   43373 	STACKTRACE_CAPTURE_ON_ENTER.
   43374 
   43375 	The names of macros are suggested by Dmitry Levin.

   43388 	      for (i = 0; i < max; i++)
   43389 		sched_yield();

   43391 	    }

   43394 
   43395 		./strace -o /dev/null -k a.out

   43411 	unwind: report expected backtracing error.
   43412 	When a file mmap'ed to the target process is unlink'ed, backtracing the
   43413 	stack would fail.  Current implementation reports it as
   43414 	"backtracing_error".  To avoid confusion, the message is changed to
   43415 	"expected_backtracing_error".
   43416 
   43417 	Here is the reproducer:
   43418 
   43419 	  $ cat ./p-deleted.c
   43420 	  #include <unistd.h>
   43421 
   43422 	  int main(int argc, char **argv) {
   43423 	    return unlink(argv[0]) < 0;
   43424 	  }
   43425 
   43426 	  $ strace -e unlink -k ./p-deleted
   43427 	  unlink("./p-deleted")                   = 0
   43428 	   > /usr/lib64/libc-2.18.so(unlink+0x7) [0xe7f17]
   43429 	   > /home/yamato/var/strace/t_unwind/p-deleted (deleted)(+0x0) [0x575]
   43430 	   > /usr/lib64/libc-2.18.so(__libc_start_main+0xf5) [0x21d65]
   43431 	   > backtracing_error [0x7ffff1365590]
   43432 	  +++ exited with 0 +++
   43433 
   43434 	p-deleted is deleted therefore backtracing_error is reported.  This
   43435 	patch records the deleted marker when making mmap cache and refers the
   43436 	recorded information in the case "backtracing_error" to switch the
   43437 	message.
   43438 
   43439 	Here is the output of this patch:
   43440 
   43441 	  $ strace -e unlink -k ./p-deleted
   43442 	  unlink("./p-deleted")                   = 0
   43443 	   > /usr/lib64/libc-2.18.so(unlink+0x7) [0xe7f17]
   43444 	   > /home/yamato/var/strace/t_unwind/p-deleted (deleted)(+0x0) [0x575]
   43445 	   > /usr/lib64/libc-2.18.so(__libc_start_main+0xf5) [0x21d65]
   43446 	   > expected_backtracing_error [0x7ffff1365590]
   43447 	  +++ exited with 0 +++
   43448 
   43449 	This solution is not perfect: if a file is unlink'ed after making the
   43450 	mmap cache and before unwinding, strace cannot have a chance to record
   43451 	the deleted marker.
   43452 
   43453 	In this version of patch, hardcoded magic number used in comparing "(delete)"
   43454 	string is replaced with strlen as suggested by Dmitry Levin.
   43455 
   43456 	In old version of patch, the deleted entry was thrown away from mmap
   43457 	cache to avoid to report "backtracing_error".  In this patch I keep it,
   43458 	and just switch the error message.
   43459 	Inspired by the review comment from Dmitry Levin.

   43463 	unwind: call unwind_tcb_fin before printing detached message.
   43464 	captured stacktrace is printed in unwind_tcb_fin if tcp->queue is not
   43465 	empty.  This should happen before printing detached message, so
   43466 	unwind_tcb_fin is moved to the top of droptcb.
   43467 
   43468 	This is implicitly suggested by Dmitry Levin in patch review process.
   43469 
   43470 2014-05-30  Masatake YAMATO  <yamato (a] redhat.com>
   43471 
   43472 	unwind: implement automatic mmap cache invalidation.
   43473 	A mmap cache belonging to a tcb was updated when a system call which
   43474 	changed the memory mapping was called.  This implementation was assumed
   43475 	the mapping was changed only by the tcb.  However, this assumption is
   43476 	incorrect if the target application is multi-threaded; more than two
   43477 	tcbs can shared the same memory mapping and a tcb can modify it without
   43478 	being noticed by the others.
   43479 
   43480 	This change introduces a global integer variable mmap_cache_generation,
   43481 	and mmap_cache_generation field to struct tcb.  The variable
   43482 	is incremented each time a process enters a syscall that can modify its
   43483 	memory mapping.  Each tcb records the value of this variable at the
   43484 	moment if  building its mmap cache.  Every mmap cache associated with
   43485 	the given tcb can be validated by comparing its mmap_cache_generation
   43486 	field with the variable mmap_cache_generation.
   43487 
   43488 	This implementation is inefficient.  If strace attaches two processes
   43489 	which don't share the memory mapping, rebuilding mmap cache of a tcb
   43490 	triggered by another tcb's mmap system call is not necessary.
   43491

   43493 
   43494 	unwind: introduce queue_t for capturing stacktrace.
   43495 	This is the second step for splitting capturing from printing.
   43496 
   43497 	New `queue' field is added to tcb.  Captured stacktrace is stored here.
   43498 	The field is initialized/finalized at unwind_tcb_init/unwind_tcb_fin.
   43499 
   43500 	New API function unwind_capture_stacktrace is added.  This function
   43501 	captures the currest stack using stracktrace_walker and records it in
   43502 	tcb.  It's printing is delayed to the next call of
   43503 	unwind_print_stacktrace.
   43504 
   43505 	unwind_print_stacktrace is extended.  Now it checks queue field of
   43506 	the given tcb at the start of function.  If the function finds a
   43507 	captured stack trace, the latter is printed using stracktrace_walker.
   43508 
   43509 	Currently unwind_capture_stacktrace invocations are added directly to
   43510 	handlers of mmap, munmap, mprotect, and execve.
   43511 
   43512 	Here is the difference of output with/without patch:
   43513 
   43514 	(without patch)
   43515 	  execve("./test-fork", ["./test-fork"], [/* 56 vars */]) = 0
   43516 	   > /usr/lib64/ld-2.18.so(check_one_fd.part.0+0x82) [0x11f0]
   43517 
   43518 	(with patch)
   43519 	  execve("./test-fork", ["./test-fork"], [/* 54 vars */]) = 0
   43520 	   > /usr/lib64/libc-2.18.so(execve+0x7) [0xbcd27]

   43527 
   43528 	In older version output lines of captured elements were built when
   43529 	printing.  In this version they are built when capturing the stack.
   43530 	As result, unneeded dynamic memory allocations are avoided.
   43531 	Suggested by Luca Clementi.
   43532 
   43533 	In older version the combination of snprintf and realloc were used.
   43534 	In this version they are replaced with asprintf.
   43535 	Suggested by Dmitry Levin.

   43544 
   43545 	unwind: introduce stacktrace_walker.
   43546 	In current implementation, the stack trace is captured and printed at
   43547 	the same time, in trace_syscall_exiting.  This approach cannot
   43548 	provide user expected information when a system call changes the
   43549 	memory mapping.  In such cases, the stack trace should be captured on
   43550 	entering syscall and printed on exiting.
   43551 
   43552 	As the initial step for splitting capturing from printing, this change
   43553 	introduces stacktrace_walker utility function.  It can be used both for
   43554 	capturing in trace_syscall_entering and printing in
   43555 	trace_syscall_exiting.

   43730 	When strace is built with large file support definitions in CFLAGS (as

   43732 	rlim_t even though the struct rlimit fields used by the system call
   43733 	interface are only 32-bit.  The SIZEOF_RLIM_T will then be 8 which
   43734 	results in bad decoding of the getrlimit and setrlimit syscalls.

   44022 
   44023 	Rewrite signal mask decoding without sigset_t.
   44024 	The sigset_t provided by libc is not quite convenient.
   44025 	In glibc, sigset_t is an array with space for 1024 bits, which is much
   44026 	more than required: all architectures supported by Linux have only 64
   44027 	signals except MIPS, which has 128.
   44028 	In bionic libc, LP32 sigset_t is only 4 bytes long, which is less than
   44029 	necessary.
   44030 
   44031 	With this change, signal mask is decoded without use of intermediate
   44032 	sigset_t structure, which saves us some cpu cycles in case of glibc with
   44033 	its inflated sigset_t, and enables build with libcs where sigset_t is
   44034 	broken.
   44035 
   44036 	Old implementation used to check each signal number in the given signal
   44037 	mask twice using sigismember().
   44038 	New implementation is based on popcount and next_set_bit() so it's
   44039 	noticeably faster.

   44137 	Add support for Altera's Nios-II softcore architecture.
   44138 	This commit adds strace support for Altera's Nios-II official
   44139 	kernel port as found in git://git.rocketboards.org/linux-socfpga.git
   44140 
   44141 	Notice that this an out-of-tree kernel architectural port, and uses the
   44142 	legacy (non-generic) system call ABI. In particular, the port doesn't
   44143 	support PTRACE_GETREGSET, so the implementation is based on PTRACE_GETREGS.
   44144 
   44145 	Given it's mandatory for new architectures to support the generic
   44146 	syscall ABI and PTRACE_GETREGSET, if the nios2 architecure is ever
   44147 	mainlined, the strace support will have to be re-factored accordingly.

   44541 	Why?
   44542 	Because we want to properly decode 32-bit aio calls

   44544 	libaio.h provides.
   44545 	(These defs are not done yet, but will eventually be done).
   44546 	Keeping our local 32-bit compat defs in sync with libaio.h
   44547 	_without seeing libaio structs_ is hard/more bug prone.
   44548 	A smaller benefit is that we don't need libaio installed.

   44712 
   44713 	Remove rt parameter from [s]printsigmask()
   44714 	In almost all cases, the parameter was 1 ("decode RT sigs too").
   44715 	This change hardwires it to be 1.
   44716 
   44717 	The cases where it was 0 are, and why the change to "decode RT sigs too"
   44718 	is fine:
   44719 
   44720 	IA64: 64-bit arch, all 64 signals fit in one word in any case.
   44721 	S390[x]: sc.oldmask is a sigset_t on kernel side,
   44722 		(sigset_t *)&sc.oldmask[0] does contain all 64 signals.
   44723 	TILE: uc.uc_sigmask is a sigset_t on kernel side,
   44724 		memcpy(&sigm, &uc.uc_sigmask, NSIG / 8) copies all 64 signals.

   44727 
   44728 	Convert some uses of long_to_sigmask+printsigmask to sprintsigmask_long.
   44729 	This allows to drop long_to_sigmask function,
   44730 	and a whole bunch of sigset_t variables.
   44731 
   44732 	Simplify some sigmask manipulations.
   44733 
   44734 	Add compat support for sys_pselect6.
   44735 
   44736 	I386: fix signedness mismatch warning.
   44737 	&i386_regs.esp is a pointer to long, not unsigned long.

   44741 
   44742 	Fix sigset printing via print_sigset().
   44743 	Replace print_sigset() with print_sigset_addr_len(),
   44744 	which takes not only addr, but also len parameter.
   44745 	This allows us to drop "do we need to print RT signals?" parameter,
   44746 	and this fixes RT signals printing in many syscalls.
   44747 
   44748 	sys_epoll_pwait: print RT signals too, print sigmask size argument.
   44749 
   44750 	sys_sigprocmask: print_sigset -> print_sigset_addr_len(current_wordsize),
   44751 	no change in functionality.
   44752 
   44753 	sys_sigpending: use print_sigset_addr_len(current_wordsize)
   44754 	instead of open-coding it.
   44755

   44757 	sys_rt_sigpending: ditto.

   44759 	sys_rt_sigtimedwait: ditto.
   44760 
   44761 	do_signalfd: print_sigset -> print_sigset_addr_len. This fixes
   44762 	RT signals printing (wasn't showing them before).
   44763 
   44764 	sys_ppoll: ditto.
   44765 
   44766 	copy_sigset_len() is folded into its only user, print_sigset_addr_len(),
   44767 	and copy_sigset() is gone.
   44768 
   44769 	While at it, checked kernel sources and noted where kernel enforces
   44770 	sigset_size == NSIG / 8 (== sizeof(kernel_sigset_t)),
   44771 	and where it allows word-sized sigset_size ([rt_]sigpending).

   44774 
   44775 	sys_rt_sigaction: fix sigset copying.
   44776 	In practice, we always copy as many bytes as syscall param says
   44777 	(8, or 16 on mips). However, malicious program can call sigaction
   44778 	with wrong sigset size. Such syscall will result in EINVAL,
   44779 	but we (strace) end up copying 128 bytes (sizeof(sigset_t)),
   44780 	which copyes some garbage from stack after struct sigaction.
   44781 
   44782 	Now we always copy NSIG / 8 bytes (which is 8 bytes, or 16 on mips).
   44783 
   44784 2013-07-18  Denys Vlasenko  <dvlasenk (a] redhat.com>
   44785 
   44786 	ARM: remove wrong NSIG = 32 define.
   44787 	ARM in fact has 64 signals (1..64), and NSIG should be 65
   44788 	(as usual, rememebr that NSIG_libc == NSIG_kernel+1).
   44789 
   44790 	I carefully reviewed all usages of NSIG. In syscall.c,
   44791 	the only usage is:
   44792 	        for (i = 0; i <= NSIG; i++)
   44793 	                if (strcasecmp(s, signame(i) + 3) == 0)...
   44794 	which is safe even if NSIG is way too big - signame(i)
   44795 	returns a well-formed string for any i.
   44796 
   44797 	In signal.c, memcpy(&sigset, &sc.sc_mask, NSIG / 8) is used by
   44798 	IA64 and TILE code, so ARM change can't affect it. And final
   44799 	usage is:
   44800 	 struct new_sigaction::unsigned long sa_mask[NSIG / sizeof(long)];
   44801 	It will grow on ARM (and become correct in the process).
   44802 	Its only use is
   44803 	 memcpy(&sigset, &sa.sa_mask, NSIG / 8);
   44804 	 printsigmask(&sigset, 1);
   44805 	which used to copy garbage in high bits, now it will copy actual data.

   44862 
   44863 	s390[x]: get rid of syscall_mode, delete code which never triggers.
   44864 	Before this change, the logic was as follows:
   44865 	syscall entry:
   44866 	  get_scno:
   44867 	    syscall_mode = GPR2
   44868 	    scno = syscall_mode unless syscall_mode == -ENOSYS
   44869 	    (if -ENOSYS, scn is retrieved by decoding current insn)
   44870 	  fixup:
   44871 	    gpr2 = GPR2
   44872 	    syscall_mode = scno unless syscall_mode == -ENOSYS
   44873 	    if (gpr2 != syscall_mode) stray_entry
   44874 	syscall exit:
   44875 	  get_res:
   44876 	    gpr2 = GRP2
   44877 	  fixup:
   44878 	    syscall_mode = scno unless syscall_mode == -ENOSYS
   44879 	    if (WAITEXECVE && gpr2 in (-ENOSYS, scno)) gpr2 = 0;
   44880 	  get_error:
   44881 	    gpr2 is retval
   44882 
   44883 	Entry fixup's if() can never trigger:
   44884 	regardless whether GPR2 is -ENOSYS or not, syscall_mode is always
   44885 	equal to GRP2 value there. So it can be removed.
   44886 
   44887 	On sysexit path, syscall mode is never used.
   44888 
   44889 	Therefore, syscall_mode variable is deleted. grp2 is read from
   44890 	GPR2 register in get_scno, redundant read in entry fixup is removed.
   44891 	As a result, entry fixup's s390 code block vanishes completely.
   44892 
   44893 	gpr2 variable is renamed s390_gpr2 to match the convention used
   44894 	by other arches.

   44912 
   44913 	Replace suspicious popen_pid assignment with an obviously correct one.
   44914 	popen_pid = vfork() does work correctly, but for a subtle reason
   44915 	that wrong assignment of 0 happens in the child _first_,
   44916 	and _then_ correct value overwrites it in the parent.
   44917 
   44918 	(And in a hyphothetical system where vfork = fork,
   44919 	popen_pid wouldn't be shared, so it will also be ok.)
   44920 
   44921 	However, it's not necessary to be difficult.
   44922 	This change makes it so that assignment is done only in parent.

   46083 
   46084 	Tweaks for -c: fixed setitimer/getitimer hack; optimized call_summary_pers()
   46085 	count_syscall() was calling setitimer/getitimer once in order to find
   46086 	smallest "tick" OS uses in time accounting, in order to use it
   46087 	for syscalls which apparently spent less than that time in syscall.
   46088 	The code assumed that this "tick" is not zero... but it is zero
   46089 	on linux-3.6.11. Which means that this hack doesn't work...
   46090 
   46091 	At least this change prevents this measurement from being done
   46092 	_repeatedly_, by initializing one_tick to -1, not 0.
   46093 
   46094 	While at it, added comments in count_syscall() explaining what we are doing.
   46095 
   46096 	Optimized call_summary_pers() a bit, by eliminating redundant tv -> float
   46097 	conversions, and prevented 0.0/0.0 which was resulting in "% time"
   46098 	being shown as "-nan" if total CPU time spent was 0.000000
   46099 	(try "strace -c /bin/true").
   46100 
   46101 	The code seems to seriously underestimate CPU usage:
   46102 	"strace -c ls -lR /usr/share >/dev/null" shows total time spent
   46103 	in syscalls to be only ~10..20% of what "time ls -lR /usr/share >/dev/null"
   46104 	shows.
   46105 
   46106 	It might be useful to have a mode where we show wall clock time
   46107 	spent in syscalls, not CPU time. It might also be more accurate.

   46115 	Open-code isprint(c) and isspace(c)
   46116 	We don't call setlocale, thus we always use C locale.
   46117 	But libc supports various other locales, and therefore
   46118 	its ctype interface is general and at times inefficient.
   46119 	For example, in glibc these macros result in function call,
   46120 	whereas for e.g. isprint(c) just c >= ' ' && c <= 0x7e
   46121 	suffices.
   46122 
   46123 	By open-coding ctype checks (we have only 4 of them)
   46124 	we avoid function calls, we get smaller code:

   46358 	MAX_QUALS was 2048, even though most arches used less than 500 entries

   46382 	The future change will need to typedef sysent to sysent0,
   46383 	which results in compile failures when "struct sysent" string
   46384 	gets mangled into "struct sysent0".

   46411 	Eliminate many SCNO_IS_VALID checks.
   46412 	By adding tcp->s_ent pointer tot syscall table entry,
   46413 	we can replace sysent[tcp->scno] references by tcp->s_ent.
   46414 	More importantly, we may ensure that tcp->s_ent is always valid,
   46415 	regardless of tcp->scno value. This allows us to drop
   46416 	SCNO_IS_VALID(tcp->scno) checks before we access syscall
   46417 	table entry.
   46418 
   46419 	We can optimize (qual_flags[tcp->scno] & QUAL_foo) checks
   46420 	with a similar technique.

   46462 	ARM: make it one-personality arch.
   46463 	ARM in fact _is_ one personality.
   46464 
   46465 	We had two personalities for it because it has a handful of
   46466 	syscalls with huge scnos (0x000f00xx).
   46467 
   46468 	Extending syscall table to have [0x000f0005] index is of course
   46469 	not a good idea.
   46470 
   46471 	Someone decided to handle that by having a separate personality
   46472 	just for these syscalls.
   46473 
   46474 	But multi-personality arch does a bit more work in other parts.
   46475 
   46476 	This patch is another alternative: "move" 0x000f00nn syscalls
   46477 	down to the entries just above last ordinary syscall,
   46478 	by manipulating scno if it falls into the 0x000f00xx range.
   46479 
   46480 	In order to not worsen genuine undefined scnos' printing,
   46481 	the code remaps scno back to actual value before printing
   46482 	"syscall_NNN" string.
   46483 
   46484 	* defs.h: Remove multi-reprsonality defines from ARM.
   46485 	* syscall.c (shuffle_scno): New function.

   46539 
   46540 	Clean up mmap decoding.
   46541 	Previous code merges too many similar, but different ways
   46542 	of decoding mmap. For example, sys_old_mmap is "params in memory"
   46543 	API... except SH[64], where it is "params in regs",
   46544 	i.e. what sys_mmap ("new mmap") function does on other arches!
   46545 
   46546 	It's much simpler when every mmap handler has same API regardless
   46547 	of arch. Where API means whether params are in regs or in memory,
   46548 	and whether offset is in bytes, pages, or 4k blocks.
   46549 
   46550 	Then we just insert correct function pointers into
   46551 	arch syscall tables.
   46552 
   46553 	It turns out there are four common mmap APIs over
   46554 	all architectures which exist in Linux kernel,
   46555 	and one outlier for S390.
   46556 
   46557 	A number of mmap decoders were plain wrong in arch tables.
   46558 	For example, BFIN has no old_mmap. It returns ENOSYS.
   46559 	I checked kernel sources for all arches nad fixed the tables.
   46560 
   46561 	There was dead code for x86_64 for old_mmap:
   46562 	x86_64 has no old_mmap.
   46563 
   46564 	* mem.c: Refactor mmap functions so that we have five mmap syscall
   46565 	handlers, each with the fixed API (not varying by arch).
   46566 	* pathtrace.c (pathtrace_match): Adjust sys_func == mmap_func checks.
   46567 	* linux/syscall.h: Declare new mmap syscall handler functions.
   46568 	* linux/arm/syscallent.h: mmap2 is sys_mmap_pgoff.
   46569 	* linux/avr32/syscallent.h: mmap is sys_mmap_pgoff.
   46570 	* linux/bfin/syscallent.h: old_mmap is ENOSYS, mmap2 is sys_mmap_pgoff.

   46595 
   46596 	Remove code which supports systems with long long off_t.
   46597 	While looking at mmap mess, did experimenting in order
   46598 	to figure out what gets used when.
   46599 
   46600 	Tried building armv4tl, armv5l, armv6l, mips, mipsel, i686,
   46601 	x86_64 and none of they have long long off_t,
   46602 	which isn't suprprising: we aren't using glibc defines
   46603 	which enable that.
   46604 
   46605 	Moreover, we SHOULD NOT use off_t in syscall decode!
   46606 	Its size depends on libc, not on arch! I.e. it is essentially
   46607 	unpredictable and can even in theory vary on the same arch
   46608 	with different libc.
   46609 
   46610 	We should use longs or long longs, in a way which matches
   46611 	architectural ABI for the given syscall. There are usually
   46612 	*at most* two permutations, no need to add yet another variable
   46613 	(sizeof(off_t)) to the mix.
   46614

   46747 	x86: zero-extend 32-bit args in syscall entry instead of sign-extension.
   46748 	Zero-extension is slightly more common that sign-extension:
   46749 	all pointers are zero-extended, and some other params are unsigned.
   46750 
   46751 	Whereas signed ones (fds, pids, etc) are often treated as

   46962 
   46963 	Fix decoding of sysctl() when oldval fields are NULL.
   46964 	If you call glibc's syscall wrapper like so:
   46965 		static int name[] = { CTL_NET, NET_IPV4, NET_IPV4_LOCAL_PORT_RANGE };
   46966 		int buffer[2] = { 32768, 61000 };
   46967 		size_t size = sizeof(buffer);
   46968 		sysctl(name, 3, 0, 0, buffer, size);
   46969 	(note that oldval/oldlenp are NULL).
   46970 
   46971 	The current strace code complains like so:
   46972 	_sysctl({{CTL_NET, NET_IPV4, NET_IPV4_LOCAL_PORT_RANGE, 38}, 3, process_vm_readv: Bad address

   46974 
   46975 	Since passing NULL for the old values is valid, handle that explicitly.
   46976 	This also simplifies the code a bit by splitting up the handling of the
   46977 	new and old args so that we only handle the new args once.
   46978 
   46979 	Now the output looks like:
   46980 	_sysctl({{CTL_NET, NET_IPV4, NET_IPV4_LOCAL_PORT_RANGE, 38}, 3, NULL, 0, 0x7fff8c0c91b0, 8) = -1 EACCES (Permission denied)
   46981 
   46982 	* system.c (sys_sysctl): Check if info.oldval is NULL first.  Move the
   46983 	processing of oldlen/info.newval/info.newlen out so they always get
   46984 	executed.  Fix the format strings so we use %lu for unsigned long rather
   46985 	than a mix of %ld and %lu.

   47176 	strace -i was fetching PC with a separate PEEKUSER

   47223 	Looking at the implementation of wrapped semtimedop() call inside glibc
   47224 	and kernel, I started to believe that timeval should be located in
   47225 	tcp->u_arg[4] and not tcp->u_arg[5].  Fortunately, tcp->u_arg[5] now
   47226 	works correctly as well, due to side effects of decode_ipc_subcall().

   47253 	Add state argument to change_syscall and fix SPARC.
   47254 	Add a state argument to change_syscall() so that SPARC can modify that

   47256 	always called within an arg_setup/arg_finish_change sequence which on
   47257 	certain architectures like SPARC will also be doing a read-modify-write.
   47258 	This prevents the second write (from arg_finish_change) from undoing the
   47259 	effects of the change_syscall call.
   47260

   47783 
   47784 	Add x32 support to strace.
   47785 	X32 support is added to Linux kernel 3.4. In a nutshell, x32 is x86-64 with
   47786 	32bit pointers.  At system call level, x32 is also identical to x86-64,
   47787 	as shown by many changes like "defined(X86_64) || defined(X32)".  The
   47788 	main differerence bewteen x32 and x86-64 is off_t in x32 is long long
   47789 	instead of long.

   47846 	Linux kernel v3.4 adds x32 support.  Both x32 and n32 use 64bit offset

   48063 
   48064 	This tells user that strace failed to let sendto syscall
   48065 	to be entered - process was dead at that point of time.
   48066 	It is (marginally) better than to always say "<unfinished ...>"
   48067 
   48068 	While at it, patch removes tcp->ptrace_errno.
   48069 	I added it many months ago, and it looks that after all
   48070 	it is not needed for ptrace error detection: I failed to execute
   48071 	a single existing code path which is accessible
   48072 	through that variable only.
   48073 
   48074 	* defs.h: Remove struct tcp::ptrace_errno field.

   48135 
   48136 	Shrink space needed by undefined syscalls in syscall tables.
   48137 	Undefined syscall looked like this before this change:
   48138 	{ 5,    0,      printargs,              "SYS_53"                },
   48139 	That is, "SYS_53" string had to be allocated and stored in strace binary.
   48140 	Since now SCNO_IN_RANGE() macro requires sysent[scno].sys_func != NULL
   48141 	for valid syscalls, we can replace printargs with NULL in such lines
   48142 	and make them "invalid", thus not requiring syscall name string.
   48143 
   48144 	Savings on i386:

   48228 
   48229 	Remove unused version of sys_lseek.
   48230 	It is buggy: it returns RVAL_LUDECIMAL, which means the return value

   48232 	(on Linux - it used to be set on other OSes).
   48233

   48242 
   48243 2012-03-17  Denys Vlasenko  <vda.linux (a] googlemail.com>
   48244 
   48245 	Simplify sys_lseek64 conditional compilation.
   48246 	It looks like sys_lseek64() is never used.
   48247 	For one, it is buggy (always shows 0 return value), and no one complains.
   48248 
   48249 	From code inspection: sys_lseek64 name is not used anywhere.
   48250 	It is defined to sys_lseek if HAVE_LONG_LONG_OFF_T is true.
   48251 	Thus, if !HAVE_LONG_LONG_OFF_T, it is never used.
   48252 	Therefore "if _LFS64_LARGEFILE || HAVE_LONG_LONG_OFF_T"
   48253 	conditional it sits in can be simplified to
   48254 	"if HAVE_LONG_LONG_OFF_T".
   48255 	Therefore, we can move it a bit up and merge with
   48256 	"if !HAVE_LONG_LONG_OFF_T, use this sys_lseek()" code block,
   48257 	by addind an "else" clause to it.
   48258 	To simplify it more, drop define and just rename sys_lseek64 ->
   48259 	sys_lseek.
   48260 
   48261 	Since the function is buggy, I think it is unused and we can
   48262 	just drop it. (I checked: at least I386 never uses it).
   48263 
   48264 	* file.c (sys_lseek64): Rename to sys_lseek; don't compile it
   48265 	if _LFS64_LARGEFILE but !HAVE_LONG_LONG_OFF_T since in this case
   48266 	it is never used.
   48267 
   48268 2012-03-17  Denys Vlasenko  <vda.linux (a] googlemail.com>
   48269 
   48270 	Remove underscores from a few syscall names which have them.
   48271 	Affected names are "_newselect", "_llseek", "_sysctl".
   48272 	I see no apparent reason why they have leading underscores.
   48273 	Moreover, some arches have underscored names and some have
   48274 	non-underscored ones. This is not consistent.
   48275 
   48276 	I verified that every architectire I touched did not have
   48277 	a similarly named syscall without underscore, thus this change
   48278 	does not introduce new ambiquities.
   48279 
   48280 	I left "_exit" untouched for now, but the same points stand for it too:
   48281 	some architectures use "exit" and no one complains. So why many
   48282 	arches are using "_exit"?
   48283 
   48284 	* linux/*/syscallent.h: Remove underscores from displayed
   48285 	syscall names for _newselect, _llseek, _sysctl.

   48426 	than the style that everyone else uses.
   48427 
   48428 	Tested with this simple code:

   48444 	osf_sigprocmask(SIG_BLOCK, [CHLD])      = 0x3 (old mask [HUP INT])
   48445 	...
   48446

   48801 2012-03-09  Denys Vlasenko  <vda.linux (a] googlemail.com>
   48802 
   48803 	Don't consider PROG to be our child in "strace -D PROG" case.
   48804 	TCB_STRACE_CHILD is used for the case when "strace PROG" is ^C-ed
   48805 	or something like that. strace should not just exit - it should
   48806 	do something with its child (such as signal it too).
   48807 
   48808 	In -D case, PROG is not really a child of _strace_, it is a child
   48809 	of strace's parent. It's ok to handle it exactly as an attached process.
   48810 
   48811 	While we are at it, remove nonsensical special-casing of TCB_STRACE_CHILD
   48812 	in printing of "<unfinished ...>" message.
   48813 
   48814 	* strace.c (startup_attach): Don't set TCB_STRACE_CHILD if -D.
   48815 	(trace): Print "<unfinished ...>" on error regardless of TCB_STRACE_CHILD.
   48816 
   48817 2012-03-09  Denys Vlasenko  <vda.linux (a] googlemail.com>
   48818 
   48819 	Fix the case where we try to detach unattached processes.
   48820 	Before this change:
   48821 	$ strace -D -p1
   48822 	strace: -D and -p are mutually exclusive options
   48823 	Process 1 detached  <==== WRONG! (and we try to SIGSTOP it!!!)
   48824 
   48825 	* defs.h: Change the meaning of TCB_ATTACHED: now it means "this tracee
   48826 	is attached to us". Add TCB_STRACE_CHILD: "this tracee is our child".
   48827 	* strace.c (kill_save_errno): Move up. No code changes.
   48828 	(process_opt_p_list): Don't set TCB_ATTACHED on new tcb.
   48829 	(startup_attach): Change how we work with TCB_ATTACHED.

   48831 	(startup_child): Use kill_save_errno instead of kill.
   48832 	Set TCB_ATTACHED and TCB_STRACE_CHILD on attached strace child.
   48833 	If we are in -D case, don't set TCB_ATTACHED (we aren't attached yet).
   48834 	(detach): do not do PTRACE_DETACH if TCB_ATTACHED is not set.
   48835 	(cleanup): Check TCB_STRACE_CHILD instead of TCB_ATTACHED.
   48836 	(trace): Likewise.

   48847 2012-03-09  Denys Vlasenko  <vda.linux (a] googlemail.com>
   48848 
   48849 	Fix PID prefix printing in "strace -oLOG -ff -p1 -p2 -p3" case.
   48850 	In this case we were printing PIDs to LOG.* files
   48851 	even though it is not necessary.
   48852 
   48853 	The fix is in the addition of "&& followfork < 2" condition.
   48854 
   48855 	* strace.c: Remove pflag_seen variable, add print_pid_pfx one.
   48856 	(process_opt_p_list): Do not pflag_seen++.
   48857 	(main): Use "nprocs != 0" condition instead of "pflag_seen != 0".
   48858 	Set print_pid_pfx before entering main tracing loop.
   48859 	(printleader): Use print_pid_pfx to decide whether to print pid prefix.

   48861 2012-03-09  Denys Vlasenko  <vda.linux (a] googlemail.com>
   48862

   48869 
   48870 	Pass addr=0 instead of 1 into restarting ptrace calls.
   48871 	While we are at it, fold do_ptrace into its lone caller.
   48872 	We no longer set tcp->ptrace_errno = ESRCH on ESRC error in upeek.
   48873 	Other code paths where ptrace fails wern't doing it, and the code which
   48874 	checks tcp->ptrace_errno even assumes it is never set to ESRCH.
   48875 	(It was me who added this code sometime ago, so it was my fault
   48876 	that it was a bit messy)
   48877 
   48878 	I ran sigkill_rain test and verified that unfinished syscalls are
   48879 	still handled correctly.
   48880 
   48881 	* util.c (ptrace_restart): Do not pass addr=1 to ptrace(), pass 0 instead.
   48882 	I have no idea why we were passing 1. Ptrace documentation says
   48883 	that addr parameter is ignored.
   48884 	(do_ptrace): Remove this function.
   48885 	(upeek): Use ptrace() instead of do_ptrace().

   49154 	The native_scno field is not so much used in the code than before.

   49302 
   49303 	Add experimental code to use PTRACE_SEIZE, disabled by default.
   49304 	All new code is predicated on "ifdef USE_SEIZE". If it is not defined,
   49305 	behavior is not changed.
   49306 
   49307 	If USE_SEIZE is enabled and run-time check shows that PTRACE_SEIZE works, then:
   49308 	- All attaching is done with PTRACE_SEIZE + PTRACE_INTERRUPT.
   49309 	  This means that we no longer generate (and possibly race with) SIGSTOP.
   49310 	- PTRACE_EVENT_STOP will be generated if tracee is group-stopped.
   49311 	  When we detect it, we issue PTRACE_LISTEN instead of PTRACE_SYSCALL.
   49312 	  This leaves tracee stopped. This fixes the inability to SIGSTOP or ^Z
   49313 	  a straced process.
   49314 
   49315 	* defs.h: Add commented-out "define USE_SEIZE 1" and define PTRACE_SEIZE
   49316 	and related constants.
   49317 	* strace.c: New variable post_attach_sigstop shows whether we age going
   49318 	to expect SIGSTOP on attach (IOW: are we going to use PTRACE_SEIZE).

   49320 	PTRACE_SEIZE + PTRACE_INTERRUPT to attach to given pid.
   49321 	(startup_attach): Use ptrace_attach_or_seize() instead of ptrace(PTRACE_ATTACH).
   49322 	(startup_child): Conditionally use alternative attach method using PTRACE_SEIZE.
   49323 	(test_ptrace_setoptions_followfork): More robust parameters to PTRACE_TRACEME.
   49324 	(test_ptrace_seize): New function to test whether PTRACE_SEIZE works.
   49325 	(main): Call test_ptrace_seize() while initializing.
   49326 	(trace): If PTRACE_EVENT_STOP is seen, restart using PTRACE_LISTEN in order
   49327 	to not let tracee run.
   49328 	* process.c: Decode PTRACE_SEIZE, PTRACE_INTERRUPT, PTRACE_LISTEN.

   49345 
   49346 	Use process_vm_readv instead of PTRACE_PEEKDATA to read data blocks.
   49347 	Currently, we use PTRACE_PEEKDATA to read things like filenames and
   49348 	data passed by I/O syscalls.
   49349 	PTRACE_PEEKDATA gets one word per syscall. This is VERY expensive.
   49350 	For example, in order to print fstat syscall, we need to perform
   49351 	more than twenty trips into kernel to fetch one struct stat!
   49352 
   49353 	Kernel 3.2 got a new syscall, process_vm_readv(), which can be used to
   49354 	copy data blocks out of process' address space.
   49355 
   49356 	This change uses it in umoven() and umovestr() functions if possible,
   49357 	with fallback to old method if process_vm_readv() fails.
   49358 	If it returns ENOSYS, we don't try to use it anymore, eliminating
   49359 	overhead of trying it on older kernels.
   49360 
   49361 	Result of "time strace -oLOG ls -l /usr/lib >/dev/null":

   49390 2012-01-28  Denys Vlasenko  <vda.linux (a] googlemail.com>
   49391 
   49392 	Fix handling of test/threaded_execve.c testcase.
   49393 	Since 3.0, Linux has a way to identify which thread execve'ed.
   49394 	This patch makes use of it in order to properly dispose
   49395 	of disappeared ("superseded") thread leader,
   49396 	and replace it with execve'ed thread.
   49397 
   49398 	Before this patch, strace was "leaking" thread which exec'ed.
   49399 	It was thinking that it still runs. It would look like this:
   49400 
   49401 	18460 pause( <unfinished ...>     <=== thread leader
   49402 	18466 execve("/proc/self/exe", ["exe", "exe"], [/* 47 vars */] <unfinished ...>
   49403 	18465 +++ exited with 0 +++       <=== exits from other threads
   49404 	18460 <... pause resumed> )             = 0
   49405 
   49406 	The last line is wrong: it's not pause resumed, it's execve resumed.
   49407 	If thread leader would do exit instead of pause, it is much worse:
   49408 	strace panics because it thinks it sees return from exit syscall!
   49409

   49465 	Use single fprintf in verror_msg()
   49466 	This change partially reverts commit 44d0532.
   49467 
   49468 	In code before commit 44d0532, single fprintf was used on purpose:
   49469 	we want to send entire message as one write() call. Since stderr
   49470 	is unbuffered, separate fprintf's to it always result in separate
   49471 	writes, they are not coalesced. If we aren't the only program
   49472 	which writes to this particular stderr, this may result
   49473 	in interleaved messages.
   49474 
   49475 	Since this function is not performance critical, I guess
   49476 	it's ok to make it less efficient.
   49477 
   49478 	* strace.c (verror_msg): Attempt to print the message in single
   49479 	write operation. Use separate fprintfs as a fallback if malloc fails.

   49554 
   49555 	Get rid of TCB_SIGTRAPPED.
   49556 	On attempts to block or set SIGTRAP handler,
   49557 	for example, using sigaction syscall, we generate
   49558 	an additional SIGSTOP.
   49559 
   49560 	This change gets rid of this SIGSTOP sending/ignoring.
   49561 	It appears to work just fine.
   49562 
   49563 	It also works if I force strace to not use PTRACE_O_TRACESYSGOOD,
   49564 	which means strace stops will be marked with SIGTRAP,
   49565 	not (SIGTRAP | 0x80) - I wondered maybe that's when
   49566 	this hack is needed.
   49567 
   49568 	So, why we even have TCB_SIGTRAPPED? No one knows. It predates
   49569 	version control: this code was present in the initial commit,
   49570 	in 1999. No adequate comments, either.
   49571 
   49572 	Moreover, TCB_SIGTRAPPED is not set in sys_rt_sigaction
   49573 	and sys_sigprocmask syscalls - the ones which are most usually
   49574 	used to implement signal blocking, it is only set in obsolete
   49575 	sys_signal, sys_sigaction, sys_sigsetmask, and in some dead
   49576 	non-Linux code.
   49577 
   49578 	I think whatever bug it was fixing is gone long ago -
   49579 	at least as long as sys_rt_sigaction is used by glibc.
   49580 	Again, since glibc (and uclibc) uses sys_rt_sigaction
   49581 	and sys_sigprocmask, modified code paths are not used
   49582 	by most programs anyway.
   49583 
   49584 	* defs.h: Remove definition of TCB_SIGTRAPPED.
   49585 	* signal.c (sys_sigvec): Don't set TCB_SIGTRAPPED and don't send SIGSTOP.
   49586 	(sys_sigsetmask): Likewise.
   49587 	(sys_sigaction): Likewise.

   49619 	Make ERESTARTxyz messages more descriptive.
   49620 	There is widespread confusion about exact meaning
   49621 	of ERESTARTxyz codes. Before this change, we were showing
   49622 	all four of them the same: as "(To be restarted)".
   49623 
   49624 	This change prints better explanations for these codes,
   49625 	and contains verbose comments which explain *why* we display
   49626 	codes that way - or else someone confused
   49627 	is bound to come later and mangle them again.
   49628 	New messages are:
   49629 
   49630 	ERESTARTSYS (To be restarted if SA_RESTART is set)

   49655 
   49656 	Display mask on enter to sigreturn, not on exit.
   49657 	sys_sigreturn() performs ugly manipulations in order to show
   49658 	signal mask which is restored by this syscall: on syscall entry,
   49659 	fetches it from the stack, saves it in tcp->u_arg[]
   49660 	(where it used to overflow this array - fixed sometime ago),
   49661 	then retrieves the mask and displays it on syscall exit.
   49662 
   49663 	Apparently, the motivation is to make it slightly more obvious
   49664 	to user that signal mask is restored only when this syscall returns.
   49665 	IMO, this hardly justifies the necessary hacks. It is much easier
   49666 	to display the mask at the point when we fetch it - on syscall entry.
   49667 
   49668 	While at it, I made it so that we do display returned value/errno.
   49669 	I see no point in hiding it and showing uninformative "= ?" instead.

   49749 	Fix sys_ipc/sys_semtimedop decoding on s390.
   49750 	The s390 kernel sys_ipc system call only takes five arguments instead of
   49751 	six arguments which the common code sys_ipc implementation takes.
   49752 	One of the arguments of the sys_semtimedop subcall is therefore passed in
   49753 	a different register than in the common code implementation.
   49754 	This leads to broken decoding of the timespec argument:
   49755 
   49756 	semtimedop(0, 0x3ffffb43832, 1, {...})  = -1 EAGAIN
   49757 
   49758 	Fixed it looks like this:
   49759 
   49760 	semtimedop(0, 0x3ffffc2c842, 1, {0, 10000000}) = -1 EINTR
   49761

   50446 	Unify per-architecture post-execve SIGTRAP check.
   50447 	Move post-execve SIGTRAP check from get_scno_on_sysenter
   50448 	(multitude of places on many architectures) to a single location
   50449 	in trace_syscall_entering. This loosens the logic for some arches,
   50450 	since many of them had additional checks such as scno == 0.
   50451 	However, on non-ancient Linux kernels we should never have post-execve
   50452 	SIGTRAP in the first place, by virtue of using PTRACE_O_TRACEEXEC.
   50453 
   50454 	* syscall.c (get_scno_on_sysenter): Remove tcp->flags & TCB_WAITEXECVE checks.

   50461 
   50462 	Speed up x86 by avoiding EAX read on syscall entry.
   50463 	on x86, EAX read on syscall entry is not necessary if we know
   50464 	that post-execve SIGTRAP is disabled by PTRACE_O_TRACEEXEC ptrace option.
   50465 	This patch (a) moves EAX retrieval from syscall_fixup
   50466 	to get_scno_on_sysexit, and (b) perform EAX retrieval in syscall_fixup
   50467 	only if we are in syscall entry and PTRACE_O_TRACEEXEC option is not on.

   50477 	* syscall.c (get_scno_on_sysexit): Remove scno retrieval code, since
   50478 	we don't save it anyway. This is the first real logic change
   50479 	which should make strace faster: for example, on x64 ORIG_EAX
   50480 	is no longer read in each syscall exit.
   50481 
   50482 	Simplify get_scno_on_sysenter/sysexit.

   50488 2011-08-24  Denys Vlasenko  <dvlasenk (a] redhat.com>
   50489 
   50490 	get_scno is an unholy mess, make it less horrible.
   50491 	Currently, get_scno does *much* more than "get syscall no".
   50492 	It checks for post-execve SIGTRAP. It checks for changes
   50493 	in personality. It retrieves params on entry and registers on exit.
   50494 	Worse still, it is different in different architectures: for example,
   50495 	for AVR32 regs are fetched in get_scno(), while for e.g. I386
   50496 	it is done in syscall_enter().
   50497 
   50498 	Another problem is that get_scno() is called on both syscall entry and
   50499 	syscall exit, which is stupid: we don't need to know scno on syscall
   50500 	exit, it is already known from last syscall entry and stored in
   50501 	tcp->scno! In essence, get_scno() does two completely different things
   50502 	on syscall entry and on exit, they are just mixed into one bottle, like
   50503 	shampoo and conditioner.
   50504 
   50505 	The following patches will try to improve this situation.
   50506 
   50507 	This change duplicates get_scno into identical get_scno_on_sysenter,
   50508 	get_scno_on_sysexit functions. Call them in syscall enter and syscall
   50509 	exit, correspondingly.
   50510 
   50511 	* defs.h: Rename get_scno to get_scno_on_sysenter; declare it only
   50512 	if USE_PROCFS.
   50513 	* strace.c (proc_open): Call get_scno_on_sysenter instead of get_scno.
   50514 	* syscall.c (get_scno): Split into two (so far identical) functions
   50515 	get_scno_on_sysenter and get_scno_on_sysexit.
   50516 	(trace_syscall_entering): Call get_scno_on_sysenter instead of get_scno.

   50546 	tcp->u_nargs won't change). This can be sped up

   50597 	    write(2, "wc: qwerty: No such file or dire"..., 38) = 38

   50740 
   50741 	Set saner MAX_ARGS (6 or 8) for X86_64 and I386.
   50742 	I noticed that tcp->u_args[MAX_ARGS] array is way larger than
   50743 	I'd expect: for all arches except HPPA it has 32 (!) elements.
   50744 
   50745 	I looked at the code and so far I spotted only one abuser of
   50746 	this fact: sys_sigreturn. On several arches, it saves sigset_t
   50747 	into tcp->u_args[1...N] on entry and prints it on exit, a-la
   50748 
   50749 	memcpy(&tcp->u_arg[1], &sc.oldmask[0], sizeof(sigset_t))
   50750 
   50751 	The problem here is that in glibc sigset_t is insanely large:
   50752 	128 bytes, and using sizeof(sigset_t) in memcpy will overrun
   50753 	&tcp->u_args[1] even with MAX_ARGS == 32:
   50754 	On 32 bits, sizeof(tcp->u_args) == 32*4 == 128 bytes!
   50755 	We may already have a bug there!
   50756 
   50757 	This commit changes the code to save NSIG / 8 bytes only.
   50758 	NSIG can't ever be > 256, and in practice is <= 129,
   50759 	thus NSIG / 8 is <= 16 bytes == 4 32-bit words,
   50760 	and even MAX_ARGS == 5 should be enough for saving signal masks.
   50761 
   50762 	* defs.h: Reduce MAX_ARGS for X86_64 and I386 from 32 to 8
   50763 	for FreeBSD and to 6 for everyone else. Add comment about current

   50782 	Optimize sys_old_mmap.
   50783 	* mem.c (sys_old_mmap): For Ia64 and 32-bit personality of x86-64,
   50784 	copy narrow parameters from userspace by single umove, not by six
   50785 	separate ones; then assign them to long u_arg[i]. For SH[64],
   50786 	avoid copying of tcp->u_arg.
   50787 	(sys_mmap): Add FIXME comment - SH64 and i386 seem to be handled

   50791 2011-08-23  Denys Vlasenko  <dvlasenk (a] redhat.com>
   50792 
   50793 	Untangle ifdef forest in sys_mmap64. No code changes.
   50794 	After careful analysis, it looks like !LINUX and ALPHA
   50795 	pass all seven parameters in registers; and in all other cases
   50796 	parameters are on stack (pointed to by tcp->u_arg[0]).
   50797 	In light of this, reorganize ifdefs, making them simpler,
   50798 	without changing any logic.
   50799 	After this, it's apparent we use tcp->u_arg[4,5,6] and possibly
   50800 	[7] without checking that it's valid to do so.
   50801 	So far, just add a comment about this.
   50802

   50838 	Fix compilation on linux 2.4.x.
   50839 	* configure.ac: Check for BLKGETSIZE64.
   50840 	* block.c (block_ioctl): Check for HAVE_BLKGETSIZE64.
   50841 
   50842 2011-08-17  Denys Vlasenko  <dvlasenk (a] redhat.com>
   50843 
   50844 	Remove tcp->parent and TCB_CLONE_THREAD.
   50845 	tcp->parent is used for only two things:
   50846 	(1) to send signal on detach via tgkill (need to know tgid).
   50847 	Solution: use tkill, it needs only tid.
   50848 	(2) to optimize out ptrace options setting for new tracees.
   50849 	Not a big deal if we drop this optimization: "set options" op is fast,
   50850 	doing it just one extra time once per each tracee is hardly measurable.
   50851 
   50852 	TCB_CLONE_THREAD is a misnomer. It used only to flag sibling we attached to
   50853 	in startup_attach. This is used to prevent infinite recursive rescanning
   50854 	of /proc/PID/task.
   50855 	Despite the name, there is no guarantee it is set only on non-leader:
   50856 	if one would run "strace -f -p THREAD_ID" and THREAD_ID is *not*
   50857 	a thread leader, strace will happily attach to it and all siblings
   50858 	and will think that THREAD_ID is the leader! Which is a bug, but
   50859 	since we no longer detach when we think tracee is going to die,
   50860 	this bug no longer matters, because we do not use the knowledge
   50861 	about thread group leaders for anything. (We used it to delay
   50862 	leader's exit).
   50863 
   50864 	IOW: after this patch strace has no need to know about threads, parents
   50865 	and children, and so on. Therefore it does not track that information.
   50866 	It treats all tracees as independent entities. Overall,
   50867 	this simplifies code a lot.
   50868 
   50869 	* defs.h: Add TCB_ATTACH_DONE flag, remove TCB_CLONE_THREAD flag
   50870 	and struct tcb::parent field.
   50871 	* process.c (internal_fork): Don't set tcpchild->parent.
   50872 	* strace.c (startup_attach): Use TCB_ATTACH_DONE flag instead of
   50873 	TCB_CLONE_THREAD to avoid attach attempts on already-attached threads.
   50874 	Unlike TCB_CLONE_THREAD, TCB_ATTACH_DONE bit is used only temporarily,
   50875 	and only in this function. We clear it on every tcb before we return.
   50876 	(detach): Use tkill instead of tgkill.
   50877 	(trace): Set ptrace options on new tracees unconditionally,
   50878 	not only when tcp->parent == NULL.
   50879 
   50880 2011-08-17  Denys Vlasenko  <dvlasenk (a] redhat.com>
   50881 
   50882 	Remove TCB_SUSPENDED constant and related code.
   50883 	Since we no longer suspend waitpid'ing tracees, we have only one case when
   50884 	we suspend tracee: when we pick up a new tracee created by clone/fork/vfork.
   50885 
   50886 	Background: on some other OSes, attach to child is done this way:
   50887 	get fork's result (pid), loop ptrace(PTRACE_ATTACH) until you hook up
   50888 	new process/thread. This is ugly and not safe, but what matters for us
   50889 	is that it doesn't require suspending. Suspending is required
   50890 	on Linux only, because on Linux attach to child is done differently.
   50891 
   50892 	On Linux, we use two methods of catching new tracee:
   50893 	adding CLONE_THREAD bit to syscall (if needed, we change
   50894 	[v]fork into clone before that), or using ptrace options.
   50895 	In both cases, it may be so that new tracee appears before one which
   50896 	created it returns from syscall. In this case, current code
   50897 	suspends new tracee until its creator returns. Only then
   50898 	strace can determine who is its parent (it needs child's pid for this,
   50899 	which is visible in parent's [v]fork/clone result).
   50900 	This is inherently racy. For example, what if SIGKILL kills
   50901 	creator after it succeeded creating child, but before it returns?
   50902 	Looks like we will have child suspended forever.
   50903 
   50904 	But after previous commit, we DO NOT NEED parent<->child link for anything.
   50905 	Therefore we do not need suspending too. Bingo!
   50906 
   50907 	This patch removes suspending code. Now new tracees will be continued
   50908 	right away. Next patch will remove tcp->parent member.
   50909 
   50910 	* defs.h: Remove TCB_SUSPENDED constant
   50911 	* process.c (handle_new_child): Delete this function.
   50912 	  (internal_fork): Do not call handle_new_child on syscall exit.
   50913 	* strace.c (handle_ptrace_event): Delete this function.
   50914 	  (trace): Do not suspend new child; remove all handling
   50915 	  of now impossible TCB_SUSPENDED condition.
   50916 
   50917 2011-08-17  Denys Vlasenko  <dvlasenk (a] redhat.com>
   50918 
   50919 	Do not detach when we think tracee is going to die.
   50920 	Current code plays some ungodly tricks, trying to not detach
   50921 	thread group leader until all threads exit.
   50922 
   50923 	Also, it detaches from a tracee when signal delivery is detected
   50924 	which will cause tracee to exit.
   50925 	This operation is racy (not to mention the determination
   50926 	whether signal is set to SIG_DFL is a horrible hack):
   50927 	after we determined that this signal is indeed fatal
   50928 	but before we detach and let process die,
   50929 	*other thread* may set a handler to this signal, and
   50930 	we will leak the process, falsely displaying it as killed!
   50931 
   50932 	I need to look in the past to figure out why we even do it.
   50933 	First guess is that it's a workaround for old kernel bugs:
   50934 	kernel used to deliver exit notifications to the tracer,
   50935 	not to real parent. These workarounds are ancient
   50936 	(internal_exit is from 1995).
   50937 
   50938 	The patch deletes the hacks. We no longer need tcp->nclone_threads,
   50939 	TCB_EXITING and TCB_GROUP_EXITING. We also lose a few rather
   50940 	ugly functions.
   50941 
   50942 	I also added a new message: "+++ exited with EXITCODE +++"
   50943 	which shows exact moment strace got exit notification.
   50944 	It is analogous to existing "+++ killed by SIG +++" message.
   50945 
   50946 	* defs.h: Delete struct tcb::nclone_threads field,
   50947 	  TCB_EXITING and TCB_GROUP_EXITING constants,
   50948 	  declarations of sigishandled() and internal_exit().
   50949 	* process.c (internal_exit): Delete this function.
   50950 	  (handle_new_child): Don't ++tcp->nclone_threads.
   50951 	* signal.c (parse_sigset_t): Delete this function.
   50952 	  (sigishandled): Delete this function.
   50953 	* strace.c (startup_attach): Don't tcbtab[tcbi]->nclone_threads++.
   50954 	  (droptcb): Don't delay dropping if tcp->nclone_threads > 0,
   50955 	  don't drop parent if its nclone_threads reached 0:
   50956 	  just drop (only) this tcb unconditionally.
   50957 	  (detach): don't drop parent.
   50958 	  (handle_group_exit): Delete this function.
   50959 	  (handle_ptrace_event): Instead of handle_group_exit, just drop tcb;
   50960 	  do not panic if we see WIFEXITED from an attached pid;
   50961 	  print "+++ exited with EXITCODE +++" for every WIFEXITED pid.
   50962 	* syscall.c (internal_syscall):	Do not treat sys_exit specially -
   50963 	  don't call internal_exit on it.
   50964 
   50965 2011-08-16  Sergei Trofimovich  <slyfox (a] gentoo.org>

   50970 2011-08-15  Denys Vlasenko  <dvlasenk (a] redhat.com>
   50971 
   50972 	Slight optimization and cleanup in trace()
   50973 	* strace.c (trace): Do not recalculate "cflag ? &ru : NULL"
   50974 	again and again. Do not clear errno unnecessarily.
   50975 	Consistently check wait errors as pid < 0, not pid == -1.
   50976 	Indent ifdefs for better readability.
   50977 	Remove comments after endif if ifdef/endif block is really tiny.
   50978 
   50979 	Fix compilation on 2.4.20 kernel based system.
   50980 	* block.c (block_ioctl): add ifdef/endif around BLKGETSIZE64 usage

   50983 2011-07-19  Dmitry V. Levin  <ldv (a] altlinux.org>
   50984

   50988 	PTRACE_EVENT_VFORK_DONE and PTRACE_EVENT_EXIT.

   51035 
   51036 	Optimize arrays of register indexes in syscall_enter.
   51037 	* syscall.c (syscall_enter) [BFIN]: Make register no array "static const".
   51038 	  [SH]: Make register no array "const", pre-multiply it by 4.
   51039 	  [SH64]: Make register no array "const".

   51042 2011-06-23  Denys Vlasenko  <dvlasenk (a] redhat.com>
   51043 
   51044 	Deindent syscall_enter by removing unnecessary braces. No code changes.
   51045 	syscall_enter has many long (>80 columns) lines.
   51046 	It is aggravated by the fact that it has a lot of {} blocks
   51047 	which are not necessary (the code is the same without them).
   51048 	This patch removes {}s and deindents affected lines.
   51049 	While at it, it indents ifdefs so that nesting is easier to track,
   51050 	and adds a few spaces in the expressions, such as
   51051 	"tcp->u_nargs*sizeof..." -> "tcp->u_nargs * sizeof...".
   51052 	There is no actual changes to the code here.
   51053 
   51054 	* syscall.c (syscall_enter): Remove unnecessary {} blocks.

   51056 2011-06-23  Denys Vlasenko  <dvlasenk (a] redhat.com>
   51057 
   51058 	Remove dead "ifndef CLONE_PTRACE" branch.
   51059 	process.c defines CLONE_PTRACE for Linux, so it can't be undefined.
   51060 	Therefore ifndef CLONE_PTRACE code is dead (since at least 2004).
   51061 	This patch removes it.
   51062 
   51063 	* process.c (handle_new_child): Remove ifdef CLONE_PTRACE/endif (but not
   51064 	  the code inside) and entire ifndef CLONE_PTRACE/endif block.

   51074 2011-06-23  Denys Vlasenko  <dvlasenk (a] redhat.com>
   51075 
   51076 	Remove TCB_FOLLOWFORK.
   51077 	TCB_FOLLOWFORK flag seems to be unnecessary, because we either follow
   51078 	all [v]forks/clones or don't follow any, therefore global variable
   51079 	followfork is an already existing indicator of what we want to do.
   51080 	This patch drops all setting/clearing of TCB_FOLLOWFORK bit,
   51081 	and replaces checks for this bit by checks of followfork value.
   51082 	In internal_fork, check is moved to in front of if(), since
   51083 	the check is needed on both "entering" and "exiting" branch.
   51084 
   51085 	* defs.h: Remove TCB_FOLLOWFORK define.
   51086 	* process.c (internal_fork): Do not set/clear TCB_FOLLOWFORK,
   51087 	  test followfork instead of tcp->flags & TCB_FOLLOWFORK.

   51101 
   51102 	Do not allocate tiny cap_user_header/data structures, place them on stack.

   51194 	Get rid of fork_tcb() function. It used to do what the comment
   51195 	above it says, but now it doesn't do much:
   51196 	it only sets tcp->flags |= TCB_FOLLOWFORK and maybe calls

   51268 	Commit 3454e4b463e6c22c7ea8c5461ef5a077f4650a54
   51269 	introduced a bug: sometimes, TRACECLONE/TRACE[V]FORK opts were not set.
   51270 	The check (tcp->parent == NULL) in old code was meant to check
   51271 	"if we are not a child created by auto-attach" - in this case,
   51272 	options need to be set on the child; otherwise they are inherited
   51273 	and do not need to be set.
   51274 	I misunderstood the check and if tcp->parent is not NULL, I was
   51275 	setting only ptrace_setoptions_for_all bits.
   51276 	This change fixes the problem. Since the fixed logic makes it
   51277 	unnecessary to keep two sets of options in separate variables,

   51294 	Do not suspend waitpid.
   51295 	strace used to suspend waitpid until there is a child
   51296 	for waitpid'ing process to collect status from.
   51297 	Apparently, it was done because in some very old kernels
   51298 	(circa 2002 or even earlier) there were ptrace bugs which

   51628 	allowing each arch to maintain its own minor list.
   51629 
   51630 	The basic method is:
   51631 	- each arch has linux/<arch>/ioctlent.h.in which defines only the
   51632 	arch-specific ioctls;
   51633 	- linux/ioctlent.h.in which defines only the common ioctls;
   51634 	- at build time, these two headers are combined and sorted to produce
   51635 	the linux/ioctlent.h file.
   51636 
   51637 	This also requires a little tweaking of the include files since the
   51638 	common ioctlent.h is a built file.

   52140 	Handle followfork using ptrace_setoptions if available.
   52141 	If PTRACE_O_TRACECLONE et al options are supported by kernel,
   52142 	use them to do followfork rather than the original setbpt
   52143 	method that changes registers ourselves.
   52144 
   52145 	* defs.h [LINUX] (handle_new_child): New function prototype.
   52146 	* process.c [LINUX] (handle_new_child): New function based on the
   52147 	code from internal_fork(), with a trivial change: do reparent only
   52148 	for sys_clone.
   52149 	[LINUX] (internal_fork): Use handle_new_child().  Do nothing if
   52150 	ptrace_setoptions is in effect.
   52151 	* strace.c [LINUX] (handle_ptrace_event): New function.
   52152 	[LINUX] (trace): If ptrace_setoptions is in effect, then

   52157 
   52158 	Test how PTRACE_SETOPTIONS support works.
   52159 	Currently test fork related options only.  Fork a child that uses
   52160 	PTRACE_TRACEME at startup and then does a fork so strace can test
   52161 	how the PTRACE_SETOPTIONS support works before it handles any real
   52162 	tracee.  Since PTRACE_O_TRACECLONE/*FORK were introduced to kernel
   52163 	at the same time, this test seems to be enough for these 3 options.
   52164 
   52165 	* defs.h [LINUX]: Define PTRACE_O_TRACECLONE et al macros here.
   52166 	(ptrace_setoptions): New variable declaration.
   52167 	* strace.c [LINUX] (test_ptrace_setoptions): New function, tests
   52168 	whether kernel supports PTRACE_O_CLONE/*FORK, the result is stored
   52169 	in the new variable ptrace_setoptions for later use.

   52218 	Fix off_t/rlim_t size checks when cross-compiling.
   52219 	The current off_t/rlim_t size checks (wrt size of long long) use AC_RUN
   52220 	which obviously doesn't work when cross-compiling.  While we don't hit
   52221 	any configure errors, the fall back code is pretty dumb (which is to say
   52222 	there isn't any).  Considering the code in question though, we can use
   52223 	some fun compiler tricks with sizeof and array lengths to turn it into
   52224 	a pure build test and avoid the RUN issue completely.
   52225 
   52226 	* m4/long_long.m4 (AC_OFF_T_IS_LONG_LONG, AC_RLIM_T_IS_LONG_LONG):

   52230 
   52231 	Fix long long little endian detection when cross-compiling.
   52232 	The long long endian detection code does an AC_TRY_RUN() and since that
   52233 	doesn't work when cross-compiling, it sets a fallback value.  However,
   52234 	rather than do any sort of default endian detection, the code simply
   52235 	sets it to "no".  This probably breaks most little endian systems out
   52236 	there when cross-compiling for them.  It certainly breaks Blackfin
   52237 	systems.  So use the common endian detection code provided by autoconf
   52238 	and key off of that when cross-compiling.
   52239 
   52240 	* configure.ac: Call AC_C_BIGENDIAN.

   52804 	sparc/linux: Rewrite to use asm/ptrace.h.
   52805 	The current sparc/linux code uses asm/reg.h, but recent Linux kernels
   52806 	dropped that header completely.  So switch over to the ptrace headers
   52807 	as those should stick around indefinitely as part of the ABI.
   52808 
   52809 	* defs.h [LINUXSPARC] (U_REG_G1, U_REG_O0, U_REG_O1): Define.

   52841 	add check for umove() return code.
   52842 	(sys_msgsnd): Use tprint_msgsnd().
   52843

   52845 
   52846 	Enhance semop()/semtimedop() sembuf parser.

   52865 
   52866 	Avoid malloc(0) in getdents parsers.
   52867 	On end of directory, getdents returns 0.  This return value is used to
   52868 	then try and do malloc(0), but on some systems this will always return
   52869 	NULL.  Since the code won't read the pointer in question if len is 0,
   52870 	then don't bother calling malloc(0) and set the pointer to NULL ourself.
   52871 	* file.c (sys_getdents, sys_getdents64): Avoid malloc(0) call.

   52996 	Add accept4 socketcall.
   52997 	This second patch in the series adds support for accept4 as a socketcall
