1 # This file is used to automatically generate bionic's system call stubs. 2 # 3 # Each non-blank, non-comment line has the following format: 4 # 5 # return_type func_name[|alias_list][:syscall_name[:socketcall_id]]([parameter_list]) arch_list 6 # 7 # where: 8 # arch_list ::= "all" | arch+ 9 # arch ::= "arm" | "arm64" | "mips" | "mips64" | "x86" | "x86_64" 10 # 11 # Note: 12 # - syscall_name corresponds to the name of the syscall, which may differ from 13 # the exported function name (example: the exit syscall is implemented by the _exit() 14 # function, which is not the same as the standard C exit() function which calls it) 15 # 16 # - alias_list is optional comma separated list of function aliases. 17 # 18 # - The call_id parameter, given that func_name and syscall_name have 19 # been provided, allows the user to specify dispatch style syscalls. 20 # For example, socket() syscall on i386 actually becomes: 21 # socketcall(__NR_socket, 1, *(rest of args on stack)). 22 # 23 # - Each parameter type is assumed to be stored in 32 bits. 24 # 25 # This file is processed by a python script named gensyscalls.py. 26 27 int execve(const char*, char* const*, char* const*) all 28 29 uid_t getuid:getuid32() arm,x86 30 uid_t getuid:getuid() arm64,mips,mips64,x86_64 31 gid_t getgid:getgid32() arm,x86 32 gid_t getgid:getgid() arm64,mips,mips64,x86_64 33 uid_t geteuid:geteuid32() arm,x86 34 uid_t geteuid:geteuid() arm64,mips,mips64,x86_64 35 gid_t getegid:getegid32() arm,x86 36 gid_t getegid:getegid() arm64,mips,mips64,x86_64 37 uid_t getresuid:getresuid32(uid_t* ruid, uid_t* euid, uid_t* suid) arm,x86 38 uid_t getresuid:getresuid(uid_t* ruid, uid_t* euid, uid_t* suid) arm64,mips,mips64,x86_64 39 gid_t getresgid:getresgid32(gid_t* rgid, gid_t* egid, gid_t* sgid) arm,x86 40 gid_t getresgid:getresgid(gid_t* rgid, gid_t* egid, gid_t* sgid) arm64,mips,mips64,x86_64 41 ssize_t readahead(int, off64_t, size_t) all 42 int getgroups:getgroups32(int, gid_t*) arm,x86 43 int getgroups:getgroups(int, gid_t*) arm64,mips,mips64,x86_64 44 pid_t getpgid(pid_t) all 45 pid_t getppid() all 46 pid_t getsid(pid_t) all 47 pid_t setsid() all 48 int setgid:setgid32(gid_t) arm,x86 49 int setgid:setgid(gid_t) arm64,mips,mips64,x86_64 50 int setuid:setuid32(uid_t) arm,x86 51 int setuid:setuid(uid_t) arm64,mips,mips64,x86_64 52 int setreuid:setreuid32(uid_t, uid_t) arm,x86 53 int setreuid:setreuid(uid_t, uid_t) arm64,mips,mips64,x86_64 54 int setresuid:setresuid32(uid_t, uid_t, uid_t) arm,x86 55 int setresuid:setresuid(uid_t, uid_t, uid_t) arm64,mips,mips64,x86_64 56 int setresgid:setresgid32(gid_t, gid_t, gid_t) arm,x86 57 int setresgid:setresgid(gid_t, gid_t, gid_t) arm64,mips,mips64,x86_64 58 void* __brk:brk(void*) all 59 int kill(pid_t, int) all 60 int tgkill(pid_t tgid, pid_t tid, int sig) all 61 int __ptrace:ptrace(int request, int pid, void* addr, void* data) all 62 63 #
