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.

The properties that logd responds to are:
|
|
|
|
name type default description
|
|
ro.logd.auditd.dmesg bool true selinux audit messages duplicated and
|
|
sent on to dmesg log
|
|
persist.logd.security bool false Enable security buffer.
|
|
ro.device_owner bool false Override persist.logd.security to false
|
|
ro.logd.kernel bool+ svelte+ Enable klogd daemon
|
|
ro.logd.statistics bool+ svelte+ Enable logcat -S statistics.
|
|
ro.debuggable number if not "1", logd.statistics &
|
|
ro.logd.kernel default false.
|
|
persist.logd.logpersistd string Enable logpersist daemon, "logcatd"
|
|
turns on logcat -f in logd context
|
|
persist.logd.size number ro Global default size of the buffer for
|
|
all log ids at initial startup, at
|
|
runtime use: logcat -b all -G <value>
|
|
ro.logd.size number svelte default for persist.logd.size. Larger
|
|
platform default sizes than 256KB are
|
|
known to not scale well under log spam
|
|
pressure. Address the spam first,
|
|
resist increasing the log buffer.
|
|
persist.logd.size.<buffer> number ro Size of the buffer for <buffer> log
|
|
ro.logd.size.<buffer> number svelte default for persist.logd.size.<buffer>
|
|
ro.config.low_ram bool false if true, logd.statistics, logd.kernel
|
|
default false, logd.size 64K instead
|
|
of 256K.
|
|
persist.logd.filter string Pruning filter to optimize content.
|
|
At runtime use: logcat -P "<string>"
|
|
ro.logd.filter string "~! ~1000/!" default for persist.logd.filter.
|
|
This default means to prune the
|
|
oldest entries of chattiest UID, and
|
|
the chattiest PID of system
|
|
(1000, or AID_SYSTEM).
|
|
persist.logd.timestamp string ro The recording timestamp source.
|
|
"m[onotonic]" is the only supported
|
|
key character, otherwise realtime.
|
|
ro.logd.timestamp string realtime default for persist.logd.timestamp
|
|
log.tag string persist The global logging level, VERBOSE,
|
|
DEBUG, INFO, WARN, ERROR, ASSERT or
|
|
SILENT. Only the first character is
|
|
the key character.
|
|
persist.log.tag string build default for log.tag
|
|
log.tag.<tag> string persist The <tag> specific logging level.
|
|
persist.log.tag.<tag> string build default for log.tag.<tag>
|
|
|
|
NB:
|
|
- bool+ - "true", "false" and comma separated list of "eng" (forced false if
|
|
ro.debuggable is not "1") or "svelte" (forced false if ro.config.low_ram is
|
|
true).
|
|
- svelte - see ro.config.low_ram for details.
|
|
- svelte+ - see ro.config.low_ram and ro.debuggable for details.
|
|
- ro - <base property> temporary override, ro.<base property> platform default.
|
|
- persist - <base property> override, persist.<base property> platform default.
|
|
- build - VERBOSE for native, DEBUG for jvm isLoggable, or developer option.
|
|
- number - support multipliers (K or M) for convenience. Range is limited
|
|
to between 64K and 256M for log buffer sizes. Individual log buffer ids
|
|
such as main, system, ... override global default.
|
|
- Pruning filter is of form of a space-separated list of [~][UID][/PID]
|
|
references, where '~' prefix means to blacklist otherwise whitelist. For
|
|
blacklisting, UID or PID may be a '!' to instead reference the chattiest
|
|
client, with the restriction that the PID must be in the UID group 1000
|
|
(system or AID_SYSTEM).
