      1 Auditd Daemon
      2 
      3 The audit daemon is a simplified version of its desktop
      4 counterpart designed to gather the audit logs from the
      5 audit kernel subsystem. The audit subsystem of the kernel
      6 includes Linux Security Modules (LSM) messages as well.
      7 
      8 To enable the audit subsystem, you must add this to your
      9 kernel config:
     10 CONFIG_AUDIT=y
     11 
     12 To enable a LSM, you must consult that LSM's documentation, the
     13 example below is for SELinux:
     14 CONFIG_SECURITY_SELINUX=y
     15 
     16 This does not include possible dependencies that may need to be
     17 satisfied for that particular LSM.

     22 persist.logd.logpersistd.size      256   logpersistd size in MB
     23 persist.logd.size          number  ro    Global default size of the buffer for

     26 ro.logd.size               number svelte default for persist.logd.size. Larger
     27                                          platform default sizes than 256KB are
     28                                          known to not scale well under log spam
     29                                          pressure. Address the spam first,
     30                                          resist increasing the log buffer.
     31 persist.logd.size.<buffer> number  ro    Size of the buffer for <buffer> log
     32 ro.logd.size.<buffer>      number svelte default for persist.logd.size.<buffer>

     36 persist.logd.filter        string        Pruning filter to optimize content.
     37                                          At runtime use: logcat -P "<string>"
     38 ro.logd.filter       string "~! ~1000/!" default for persist.logd.filter.
     39                                          This default means to prune the
     40                                          oldest entries of chattiest UID, and
     41                                          the chattiest PID of system
     42                                          (1000, or AID_SYSTEM).
     43 persist.logd.timestamp     string  ro    The recording timestamp source.
     44                                          "m[onotonic]" is the only supported
     45                                          key character, otherwise realtime.
     46 ro.logd.timestamp        string realtime default for persist.logd.timestamp
     47 log.tag                   string persist The global logging level, VERBOSE,
     48                                          DEBUG, INFO, WARN, ERROR, ASSERT or
     49                                          SILENT. Only the first character is
     50                                          the key character.
     51 persist.log.tag            string build  default for log.tag
     52 log.tag.<tag>             string persist The <tag> specific logging level.
     53 persist.log.tag.<tag>      string build  default for log.tag.<tag>
     54 
     55 NB:
     56 - auto - managed by /init
     57 - bool+ - "true", "false" and comma separated list of "eng" (forced false if
     58   ro.build.type is "user") or "svelte" (forced false if ro.config.low_ram is
     59   true).
     60 - svelte - see ro.config.low_ram for details.
     61 - svelte+ - see ro.config.low_ram and ro.build.type for details.
     62 - ro - <base property> temporary override, ro.<base property> platform default.
     63 - persist - <base property> override, persist.<base property> platform default.
     64 - build - VERBOSE for native, DEBUG for jvm isLoggable, or developer option.
     65 - number - support multipliers (K or M) for convenience. Range is limited
     66   to between 64K and 256M for log buffer sizes. Individual log buffer ids
     67   such as main, system, ... override global default.
     68 - Pruning filter is of form of a space-separated list of [~][UID][/PID]
     69   references, where '~' prefix means to blacklist otherwise whitelist. For
     70   blacklisting, UID or PID may be a '!' to instead reference the chattiest
     71   client, with the restriction that the PID must be in the UID group 1000
     72   (system or AID_SYSTEM).
