* Use ro.logd.kernel for kernel logcatSiarhei Vishniakou2018-01-021-3/+3
| | | | | | | | Prevent a possible DOS of the kernel logs because the runtime result could differ from the boottime result. Test: adb bugreport, then examine kernel log Change-Id: I140fd465f2e691c751d92af50dbdf95e23c121d8
* logd: Add support for ro.logd.auditd.[main|events]Mark Salyzyn2017-01-031-2/+3
| | | | | | | | | | | | | | | | | | | | | log selinux audit messages boolean (true or false, default true) selection for logging destinations: ro.logd.auditd - turn on logd.auditd to pick up violations. ro.logd.auditd.dmesg - to the kernel log. ro.logd.auditd.main - to the "main" log buffer. ro.logd.auditd.events - to the "events" log buffer. We used to also read logd.auditd.dmesg and persist.logd.auditd.dmesg which do not get refreshed when /data mounts internally. This is a confusing state as these properties will be read after a logd crash and restart, adjusting the behavior of the logger. Same can be said for logd.auditd as well. Drop reading these other parameters. Test: manual set r/o parameters, stop/start logd to confirm behavior Bug: 33969000 Bug: 27878170 Change-Id: I1a6bb4a903074c9aa7b227cf583a0094d49cbefd
* Merge \"logcatd: trampoline persist.logd.logpersistd to logd.logpersistd\"Mark Salyzyn2016-07-131-2/+11

| * logcatd: trampoline persist.logd.logpersistd to logd.logpersistdMark Salyzyn2016-07-081-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Best practices so that device can set logd.logpersistd properties. Values can be overriden with trampolines for persist.logd.logpersistd values except as designed for empty content to keep out of the way. This allows us to set logd.logpersistd* for a non-persistent collection that does not survive a reboot, and to use persist.logd.logpersistd* for persistent collection that does survive a reboot. Added logd.logpersistd.enable to gate when logpersist service can be run allowing the properties to be adjusted safely prior to this state as is the case for device property. NB: /init will complain when trying to trampoline an empty property, this is acceptable for functionality, but may be considered annoying from the logging perspective.

| * logd: enforce policy integritySami Tolvanen2016-02-221-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a SELinux policy change or a switch to permissive mode is detected on a user build, restart the device into safe mode, and keep it there until an OTA is applied or user data is wiped. This change deprecates the ro.logd.auditd property. Needs matching changes from I781c3059ea8d4fb2f0c923e4488b1932d69678d3 Ica825cf2af74f5624cf4091544bd24bb5482dbe7 Id3ca7889ede30b54b7af73dd50653ca1a20d59aa Bug: 26902605 Change-Id: Idcdc5bff133f13c1267f0ec0a75cc8cf1ddbda0d (cherry picked from commit d122ee65b66b5b33d51302dabbaa0d6c84597549)

* logd: document ro.logd.sizeMark Salyzyn2016-01-051-1/+5
| | | | | | | | | | | | | | Bad comment advise in LogBuffer.cpp results in partners failing to considering using ro.logd.size to set the platform buffer size default. NB: It is not good practice to increase the log buffer size to deal with logspam, as increases will result in logd scale issues getting closer to hitting the background cgroup cpu cap. Once we hit that cap, logd spirals, pruning old entries slower than the incoming log entries. logd.writer will take 100% cpu. Change-Id: If4a7a74f300d078eeaed0ffd3eb3fd77d1f9fe90

| | | | | | | | | | | | | | | | | | | | - enhance property_get_bool, drop property_get_bool_svelte - enhance base properties with ro and persist variants - update and fortify README.property - primarily move auditd and kernel logger into a realm where they can be controlled by build properties. - Move logd.klogd to logd.kernel, and add ro.logd.kernel and persist.logd.kernel. - Add ro.logd.auditd and persist.logd.auditd. - Document persist.logd.security - Document log.tag and persist.logd.tag properties. - Document ro.logd.size, persist.logd.size and logd.size properties.

* liblog: logd: support logd.timestamp = monotonicMark Salyzyn2015-11-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | if ro.logd.timestamp or persist.logd.timestamp are set to the value monotonic then liblog writer, liblog printing and logd all switch to recording/printing monotonic time rather than realtime. If reinit detects a change for presist.logd.timestamp, correct the older entry timestamps in place. ToDo: A corner case condition where new log entries in monotonic time occur before logd reinit detects persist.logd.timestamp, there will be a few out-of-order entries, but with accurate timestamps. This problem does not happen for ro.logd.timestamp as it is set before logd starts. NB: This offers a nano second time accuracy on all log entries that may be more suitable for merging with other system activities, such as systrace, that also use monotonic time. This feature is for debugging. Bug: 23668800 Change-Id: Iee6dab7140061b1a6627254921411f61b01aa5c2
* logd: Add support for *.logd.filterMark Salyzyn2015-10-301-6/+14
| | | | | | | | | - Add device (ro.logd.filter), persistent (persist.logd.filter) properties to control the default filters - Allow logcat -P default to produce expected results - Allow logcat -P disable to produce expected results Change-Id: I651cb705373ec1e88a99e4b9086da4f9668a468a
* init.rc: logd: Add logpersistd (nee logcatd)Mark Salyzyn2015-06-021-0/+2
| | | | | | | | | | | | | | | | | - logpersistd is defined as a thread or process in the context of the logd domain. Here we define logpersistd as logcat -f in logd domain and call it logcatd to represent its service mechanics. - Use logcatd to manage content in /data/misc/logd/ directory. - Only turn on for persist.logd.logpersistd = logcatd. - Add logpersist.start, logpersist.stop and logpersist.cat debug class executables, thus only in the eng and userdebug builds. ToDo: Wish to add Developer Options menu to turn this feature on or off, complicated by the fact that user builds have no tools with access rights to /data/misc/logd.

* logd: Add klogdMark Salyzyn2015-05-121-2/+5
| | | | | | | | | | | | | | | | - Add a klogd to collect the kernel logs and place them into a new kernel log buffer - Parse priority, tag and message from the kernel log messages. - Turn off pruning for worst UID for the kernel log buffer - Sniff for 'PM: suspend exit', 'PM: suspend enter' and 'Suspended for' messages and correct the internal definition time correction against monotonic dynamically. - Discern if we have monotonic or real time (delineation 1980) in audit messages. - perform appropriate math to correct the timestamp to be real time - filter out any external sources of kernel logging Change-Id: I8d4c7c5ac19f1f3218079ee3a05a50e2ca55f60d
