+# Android Live-LocK Daemon (llkd)
 
-Operations
-----------
+Android 10 <!-- {{ androidQVersionNumber }} --> includes the Android Live-LocK Daemon
+(`llkd`), which is designed to catch and mitigate kernel deadlocks. The `llkd`
+component provides a default standalone implementation, but you can
+alternatively integrate the `llkd` code into another service, either as part of
+the main loop or as a separate thread.
 
-There are two detection scenarios. Persistent D or Z state, and persistent
+## Detection scenarios <!-- {:#detection-scenarios} -->
+
+The `llkd` has two detection scenarios: Persistent D or Z state, and persistent
 stack signature.
 
-If a thread is in D or Z state with no forward progress for longer than
-ro.llk.timeout_ms, or ro.llk.[D|Z].timeout_ms, kill the process or parent
-process respectively.  If another scan shows the same process continues to
-exist, then have a confirmed live-lock condition and need to panic.  Panic
-the kernel in a manner to provide the greatest bugreporting details as to the
-condition.  Add a alarm self watchdog should llkd ever get locked up that is
-double the expected time to flow through the mainloop.  Sampling is every
-ro.llk_sample_ms.
+### Persistent D or Z state <!-- {:#persistent-d-or-z-state} -->
 
-For usedebug releases only, persistent stack signature checking is enabled.
-If a thread in any state but Z, has a persistent listed ro.llk.stack kernel
-symbol always being reported, even if there is forward scheduling progress, for
-longer than ro.llk.timeout_ms, or ro.llk.stack.timeout_ms, then issue a kill
-to the process.  If another scan shows the same process continues to exist,
-then have a confirmed live-lock condition and need to panic.  There is no
-ABA detection since forward scheduling progress is allowed, thus the condition
-for the symbols are:
+If a thread is in D (uninterruptible sleep) or Z (zombie) state with no forward
+progress for longer than `ro.llk.timeout_ms or ro.llk.[D|Z].timeout_ms`, the
+`llkd` kills the process (or parent process). If a subsequent scan shows the
+same process continues to exist, the `llkd` confirms a live-lock condition and
+panics the kernel in a manner that provides the most detailed bug report for the
+condition.
 
-- Check is looking for " __symbol__+0x" or " __symbol__.cfi+0x" in
-  /proc/__pid__/stack.
-- The __symbol__ should be rare and short lived enough that on a typical
-  system the function is seen at most only once in a sample over the timeout
-  period of ro.llk.stack.timeout_ms, samples occur every ro.llk.check_ms. This
-  can be the only way to prevent a false trigger as there is no ABA protection.
-- Persistent continuously when the live lock condition exists.
-- Should be just below the function that is calling the lock that could
-  contend, because if the lock is below or in the symbol function, the
-  symbol will show in all affected processes, not just the one that
-  caused the lockup.
+The `llkd` includes a self watchdog that alarms if `llkd` locks up; watchdog is
+double the expected time to flow through the mainloop and sampling is every
+`ro.llk_sample_ms`.
 
-Default will not monitor init, or [kthreadd] and all that [kthreadd] spawns.
-This reduces the effectiveness of llkd by limiting its coverage.  If there is
-value in covering [kthreadd] spawned threads, the requirement will be that
-the drivers not remain in a persistent 'D' state, or that they have mechanisms
-to recover the thread should it be killed externally (this is good driver
-coding hygiene, a common request to add such to publicly reviewed kernel.org
-maintained drivers).  For instance use wait_event_interruptible() instead of
-wait_event().  The blacklists can be adjusted accordingly if these
-conditions are met to cover kernel components.  For the stack symbol checking,
-there is an additional process blacklist so that we do not incide sepolicy
-violations on services that block ptrace operations.
+### Persistent stack signature <!-- {:#persistent-stack-signature} -->
 
-An accompanying gTest set have been added, and will setup a persistent D or Z
-process, with and without forward progress, but not in a live-lock state
-because that would require a buggy kernel, or a module or kernel modification
-to stimulate.  The test will check that llkd will mitigate first by killing
-the appropriate process.  D state is setup by vfork() waiting for exec() in
-child process.  Z state is setup by fork() and an un-waited for child process.
-Should be noted that both of these conditions should never happen on Android
-on purpose, and llkd effectively sweeps up processes that create these
-conditions.  If the test can, it will reconfigure llkd to expedite the test
-duration by adjusting the ro.llk.* Android properties.  Tests run the D state
-with some scheduling progress to ensure that ABA checking prevents false
-triggers. If 100% reliable ABA on platform, then ro.llk.killtest can be
-set to false; however this will result in some of the unit tests to panic
-kernel instead of deal with more graceful kill operation.
+For userdebug releases, the `llkd` can detect kernel live-locks using persistent
+stack signature checking. If a thread in any state except Z has a persistent
+listed `ro.llk.stack` kernel symbol that is reported for longer than
+`ro.llk.timeout_ms` or `ro.llk.stack.timeout_ms`, the `llkd` kills the process
+(even if there is forward scheduling progress). If a subsequent scan shows the
+same process continues to exist, the `llkd` confirms a live-lock condition and
+panics the kernel in a manner that provides the most detailed bug report for the
+condition.
 
-Android Properties
-------------------
+Note: Because forward scheduling progress is allowed, the `llkd` does not
+perform [ABA detection](https://en.wikipedia.org/wiki/ABA_problem){:.external}.
 
-The following are the Android Properties llkd respond to.
-*prop*_ms named properties are in milliseconds.
-Properties that use comma (*,*) separator for lists, use a leading separator to
-preserve default and add or subtract entries with (*optional*) plus (*+*) and
-minus (*-*) prefixes respectively.
-For these lists, the string "*false*" is synonymous with an *empty* list,
-and *blank* or *missing* resorts to the specified *default* value.
+The `lldk` check persists continuously when the live lock condition exists and
+looks for the composed strings `" symbol+0x"` or `" symbol.cfi+0x"` in the
+`/proc/pid/stack` file on Linux. The list of symbols is in `ro.llk.stack` and
+defaults to the comma-separated list of
+"`cma_alloc,__get_user_pages,bit_wait_io,wait_on_page_bit_killable`".
 
-#### ro.config.low_ram
-device is configured with limited memory.
+Symbols should be rare and short-lived enough that on a typical system the
+function is seen only once in a sample over the timeout period of
+`ro.llk.stack.timeout_ms` (samples occur every `ro.llk.check_ms`). Due to lack
+of ABA protection, this is the only way to prevent a false trigger. The symbol
+function must appear below the function calling the lock that could contend. If
+the lock is below or in the symbol function, the symbol appears in all affected
+processes, not just the one that caused the lockup.
 
-#### ro.debuggable
-device is configured for userdebug or eng build.
+## Coverage <!-- {:#coverage} -->
 
-#### ro.llk.sysrq_t
-default not ro.config.low_ram, or ro.debuggable if property is "eng".
-if true do sysrq t (dump all threads).
+The default implementation of `llkd` does not monitor `init`, `[kthreadd]`, or
+`[kthreadd]` spawns. For the `llkd` to cover `[kthreadd]`-spawned threads:
 
-#### ro.llk.enable
-default false, allow live-lock daemon to be enabled.
+* Drivers must not remain in a persistent D state,
 
-#### llk.enable
-default ro.llk.enable, and evaluated for eng.
+OR
 
-#### ro.khungtask.enable
-default false, allow [khungtask] daemon to be enabled.
+* Drivers must have mechanisms to recover the thread should it be killed
+  externally. For example, use `wait_event_interruptible()` instead of
+  `wait_event()`.
 
-#### khungtask.enable
-default ro.khungtask.enable and evaluated for eng.
+If one of the above conditions is met, the `llkd` ignorelist can be adjusted to
+cover kernel components.  Stack symbol checking involves an additional process
+ignore list to prevent sepolicy violations on services that block `ptrace`
+operations.
 
-#### ro.llk.mlockall
-default false, enable call to mlockall().
+## Android properties <!-- {:#android-properties} -->
 
-#### ro.khungtask.timeout
-default value 12 minutes, [khungtask] maximum timelimit.
+The `llkd` responds to several Android properties (listed below).
 
-#### ro.llk.timeout_ms
-default 10 minutes, D or Z maximum timelimit, double this value and it sets
-the alarm watchdog for llkd.
+* Properties named `prop_ms` are in milliseconds.
+* Properties that use comma (,) separator for lists use a leading separator to
+  preserve the default entry, then add or subtract entries with optional plus
+  (+) and minus (-) prefixes respectively. For these lists, the string "false"
+  is synonymous with an empty list, and blank or missing entries resort to the
+  specified default value.
 
-#### ro.llk.D.timeout_ms
-default ro.llk.timeout_ms, D maximum timelimit.
+### ro.config.low_ram <!-- {:#ro-config-low-ram} -->
 
-#### ro.llk.Z.timeout_ms
-default ro.llk.timeout_ms, Z maximum timelimit.
+Device is configured with limited memory.
 
-#### ro.llk.stack.timeout_ms
-default ro.llk.timeout_ms,
-checking for persistent stack symbols maximum timelimit.
-Only active on userdebug or eng builds.
+### ro.debuggable <!-- {:#ro-debuggable} -->
 
-#### ro.llk.check_ms
-default 2 minutes samples of threads for D or Z.
+Device is configured for userdebug or eng build.
 
-#### ro.llk.stack
-default cma_alloc,__get_user_pages,bit_wait_io,wait_on_page_bit_killable
-comma separated list of kernel symbols.
-Look for kernel stack symbols that if ever persistently present can
-indicate a subsystem is locked up.
-Beware, check does not on purpose do forward scheduling ABA except by polling
-every ro.llk_check_ms over the period ro.llk.stack.timeout_ms, so stack symbol
-should be exceptionally rare and fleeting.
-One must be convinced that it is virtually *impossible* for symbol to show up
-persistently in all samples of the stack.
-Again, looks for a match for either " **symbol**+0x" or " **symbol**.cfi+0x"
-in stack expansion.
-Only available on userdebug or eng builds, limited privileges due to security
-concerns on user builds prevents this checking.
+### ro.llk.sysrq_t <!-- {:#ro-llk-sysrq-t} -->
 
-#### ro.llk.blacklist.process
-default 0,1,2 (kernel, init and [kthreadd]) plus process names
-init,[kthreadd],[khungtaskd],lmkd,llkd,watchdogd,
-[watchdogd],[watchdogd/0],...,[watchdogd/***get_nprocs**-1*].
-Do not watch these processes.  A process can be comm, cmdline or pid reference.
-NB: automated default here can be larger than the current maximum property
-size of 92.
-NB: false is a very very very unlikely process to want to blacklist.
+If property is "eng", the default is not `ro.config.low_ram` or `ro.debuggable`.
+If true, dump all threads (`sysrq t`).
 
-#### ro.llk.blacklist.parent
-default 0,2,adbd&[setsid] (kernel, [kthreadd] and adbd *only for zombie setsid*).
-Do not watch processes that have this parent.
-An ampersand (*&*) separator is used to specify that the parent is ignored
-only in combination with the target child process.
-Ampersand was selected because it is never part of a process name,
-however a setprop in the shell requires it to be escaped or quoted;
-init rc file where this is normally specified does not have this issue.
-A parent or target processes can be specified as comm, cmdline or pid reference.
+### ro.llk.enable <!-- {:#ro-llk-enable} -->
 
-#### ro.llk.blacklist.uid
-default *empty* or false, comma separated list of uid numbers or names.
-Do not watch processes that match this uid.
+Allow live-lock daemon to be enabled. Default is false.
 
-#### ro.llk.blacklist.process.stack
-default process names init,lmkd.llkd,llkd,keystore,ueventd,apexd,logd.
-This subset of processes are not monitored for live lock stack signatures.
-Also prevents the sepolicy violation associated with processes that block
-ptrace, as these can not be checked anyways.
-Only active on userdebug and eng builds.
+### llk.enable <!-- {:#llk-enable} -->
 
-Architectural Concerns
-----------------------
+Evaluated for eng builds. Default is `ro.llk.enable`.
 
-- built-in [khungtask] daemon is too generic and trips on driver code that
-  sits around in D state too much.  To switch to S instead makes the task(s)
-  killable, so the drivers should be able to resurrect them if needed.
-- Properties are limited to 92 characters.
-- Create kernel module and associated gTest to actually test panic.
-- Create gTest to test out blacklist (ro.llk.blacklist.*properties* generally

-- Speed up gTest using something else than ro.llk.*properties*, which should
-  not be inputs as they should be baked into the product.
+### ro.khungtask.enable <!-- {:#ro-khungtask-enable} -->
+
+Allow `[khungtask]` daemon to be enabled. Default is false.
+
+### khungtask.enable <!-- {:#khungtask-enable} -->
+
+Evaluated for eng builds. Default is `ro.khungtask.enable`.
+
+### ro.llk.mlockall <!-- {:#ro-llk-mlockall} -->
+
+Enable call to `mlockall()`. Default is false.
+
+### ro.khungtask.timeout <!-- {:#ro-khungtask-timeout} -->
+
+`[khungtask]` maximum time limit. Default is 12 minutes.
+
+### ro.llk.timeout_ms <!-- {:#ro-llk-timeout-ms} -->
+
+D or Z maximum time limit. Default is 10 minutes. Double this value to set the
+alarm watchdog for `llkd`.
+
+### ro.llk.D.timeout_ms <!-- {:#ro-llk-D-timeout-ms} -->
+
+D maximum time limit. Default is `ro.llk.timeout_ms`.
+
+### ro.llk.Z.timeout_ms <!-- {:#ro-llk-Z-timeout-ms} -->
+
+Z maximum time limit. Default is `ro.llk.timeout_ms`.
+
+### ro.llk.stack.timeout_ms <!-- {:#ro-llk-stack-timeout-ms} -->
+
+Checks for persistent stack symbols maximum time limit. Default is
+`ro.llk.timeout_ms`. **Active only on userdebug or eng builds**.
+
+### ro.llk.check_ms <!-- {:#ro-llk-check-ms} -->
+
+Samples of threads for D or Z. Default is two minutes.
+
+### ro.llk.stack <!-- {:#ro-llk-stack} -->
+
+Checks for kernel stack symbols that if persistently present can indicate a
+subsystem is locked up. Default is
+`cma_alloc,__get_user_pages,bit_wait_io,wait_on_page_bit_killable`
+comma-separated list of kernel symbols. The check doesn't do forward scheduling
+ABA except by polling every `ro.llk_check_ms` over the period
+`ro.llk.stack.timeout_ms`, so stack symbols should be exceptionally rare and
+fleeting (it is highly unlikely for a symbol to show up persistently in all
+samples of the stack). Checks for a match for `" symbol+0x"` or
+`" symbol.cfi+0x"` in stack expansion. **Available only on userdebug or eng
+builds**; security concerns on user builds result in limited privileges that
+prevent this check.
+
+### ro.llk.ignorelist.process <!-- {:#ro-llk-ignorelist-process} -->
+
+The `llkd` does not watch the specified processes. Default is `0,1,2` (`kernel`,
+`init`, and `[kthreadd]`) plus process names
+`init,[kthreadd],[khungtaskd],lmkd,llkd,watchdogd, [watchdogd],[watchdogd/0],...,[watchdogd/get_nprocs-1]`.
+A process can be a `comm`, `cmdline`, or `pid` reference. An automated default
+can be larger than the current maximum property size of 92.
+
+Note: `false` is an extremely unlikely process to want to ignore.
+
+### ro.llk.ignorelist.parent <!-- {:#ro-llk-ignorelist-parent} -->
+
+The `llkd` does not watch processes that have the specified parent(s). Default
+is `0,2,adbd&[setsid]` (`kernel`, `[kthreadd]`, and `adbd` only for zombie
+`setsid`). An ampersand (&) separator specifies that the parent is ignored only
+in combination with the target child process. Ampersand was selected because it
+is never part of a process name; however, a `setprop` in the shell requires the
+ampersand to be escaped or quoted, although the `init rc` file where this is
+normally specified does not have this issue. A parent or target process can be a
+`comm`, `cmdline`, or `pid` reference.
+
+### ro.llk.ignorelist.uid <!-- {:#ro-llk-ignorelist-uid} -->
+
+The `llkd` does not watch processes that match the specified uid(s).
+Comma-separated list of uid numbers or names. Default is empty or false.
+
+### ro.llk.ignorelist.process.stack <!-- {:#ro-llk-ignorelist-process-stack} -->
+
+The `llkd` does not monitor the specified subset of processes for live lock stack
+signatures. Default is process names
+`init,lmkd.llkd,llkd,keystore,ueventd,apexd,logd`. Prevents the sepolicy
+violation associated with processes that block `ptrace` (as these can't be
+checked). **Active only on userdebug and eng builds**. For details on build
+types, refer to [Building Android](/setup/build/building#choose-a-target).
+
+## Architectural concerns <!-- {:#architectural-concerns} -->
+
+* Properties are limited to 92 characters.  However, this is not limited for
+  defaults defined in the `include/llkd.h` file in the sources.
+* The built-in `[khungtask]` daemon is too generic and trips on driver code that
+  sits around in D state too much. Switching drivers to sleep, or S state,
+  would make task(s) killable, and need to be resurrectable by drivers on an
+  as-need basis.
+
+## Library interface (optional) <!-- {:#library-interface-optional} -->
+
+You can optionally incorporate the `llkd` into another privileged daemon using
+the following C interface from the `libllkd` component:
+
+```
+#include "llkd.h"
+bool llkInit(const char* threadname) /* return true if enabled */
+unsigned llkCheckMillseconds(void)   /* ms to sleep for next check */
+```
+
+If a threadname is provided, a thread automatically spawns, otherwise the caller
+must call `llkCheckMilliseconds` in its main loop. The function returns the
+period of time before the next expected call to this handler.
