Tetsuo Handa	f12e8cf6b1	lockdep: Add a missing initialization hint to the "INFO: Trying to register non-static key" message ... [ Upstream commit 3a85969e9d ] Since this message is printed when dynamically allocated spinlocks (e.g. kzalloc()) are used without initialization (e.g. spin_lock_init()), suggest to developers to check whether initialization functions for objects were called, before making developers wonder what annotation is missing.

Arnd Bergmann	c65a000a23	lockdep: Address clang -Wformat warning printing for %hd ... commit 6d48b7912c upstream. Clang doesn't like format strings that truncate a 32-bit value to something shorter: kernel/locking/lockdep.c:709:4: error: format specifies type 'short' but the argument has type 'int' [-Werror,-Wformat] In this case, the warning is a slightly questionable, as it could realize that both class->wait_type_outer and class->wait_type_inner are in fact 8-bit struct members, even though the result of the ?: operator becomes an 'int'. However, there is really no point in printing the number as a 16-bit 'short' rather than either an 8-bit or 32-bit number, so just change it to a normal %d.

Waiman Long	905ef030bd	locking/ww_mutex: Simplify use_ww_ctx & ww_ctx handling ... [ Upstream commit 5de2055d31 ] The use_ww_ctx flag is passed to mutex_optimistic_spin(), but the function doesn't use it. The frequent use of the (use_ww_ctx && ww_ctx) combination is repetitive. In fact, ww_ctx should not be used at all if !use_ww_ctx. Simplify ww_mutex code by dropping use_ww_ctx from mutex_optimistic_spin() an clear ww_ctx if !use_ww_ctx. In this way, we can replace (use_ww_ctx && ww_ctx) by just (ww_ctx).

Boqun Feng	d61fc96a37	lockdep: Avoid to modify chain keys in validate_chain() ... Chris Wilson reported a problem spotted by check_chain_key(): a chain key got changed in validate_chain() because we modify the ->read in validate_chain() to skip checks for dependency adding, and ->read is taken into calculation for chain key since commit f611e8cf98 ("lockdep: Take read/write status in consideration when generate chainkey"). Fix this by avoiding to modify ->read in validate_chain() based on two facts: a) since we now support recursive read lock detection, there is no need to skip checks for dependency adding for recursive readers, b) since we have a), there is only one case left (nest_lock) where we want to skip checks in validate_chain(), we simply remove the modification for ->read and rely on the return value of check_deadlock() to skip the dependency adding.

Peter Zijlstra	d48e385003	locking/lockdep: Remove more raw_cpu_read() usage ... I initially thought raw_cpu_read() was OK, since if it is !0 we have IRQs disabled and can't get migrated, so if we get migrated both CPUs must have 0 and it doesn't matter which 0 we read. And while that is true; it isn't the whole store, on pretty much all architectures (except x86) this can result in computing the address for one CPU, getting migrated, the old CPU continuing execution with another task (possibly setting recursion) and then the new CPU reading the value of the old CPU, which is no longer 0.

Boqun Feng	6d1823ccc4	lockdep: Optimize the memory usage of circular queue ... Qian Cai reported a BFS_EQUEUEFULL warning [1] after read recursive deadlock detection merged into tip tree recently. Unlike the previous lockep graph searching, which iterate every lock class (every node in the graph) exactly once, the graph searching for read recurisve deadlock detection needs to iterate every lock dependency (every edge in the graph) once, as a result, the maximum memory cost of the circular queue changes from O(V), where V is the number of lock classes (nodes or vertices) in the graph, to O(E), where E is the number of lock dependencies (edges), because every lock class or dependency gets enqueued once in the BFS. Therefore we hit the BFS_EQUEUEFULL case. However, actually we don't need to enqueue all dependencies for the BFS, because every time we enqueue a dependency, we almostly enqueue all other dependencies in the same dependency list ("almostly" is because we currently check before enqueue, so if a dependency doesn't pass the check stage we won't enqueue it, however, we can always do in reverse ordering), based on this, we can only enqueue the first dependency from a dependency list and every time we want to fetch a new dependency to work, we can either: 1) fetch the dependency next to the current dependency in the dependency list or 2) if the dependency in 1) doesn't exist, fetch the dependency from the queue. With this approach, the "max bfs queue depth" for a x86_64_defconfig + lockdep and selftest config kernel can get descreased from: max bfs queue depth: 201 to (after apply this patch) max bfs queue depth: 61 While I'm at it, clean up the code logic a little (e.g. directly return other than set a "ret" value and goto the "exit" label).

Hou Tao	e6b1a44ecc	locking/percpu-rwsem: Use this_cpu_{inc,dec}() for read_count ... The __this_cpu*() accessors are (in general) IRQ-unsafe which, given that percpu-rwsem is a blocking primitive, should be just fine. However, file_end_write() is used from IRQ context and will cause load-store issues on architectures where the per-cpu accessors are not natively irq-safe. Fix it by using the IRQ-safe this_cpu_*() for operations on read_count. This will generate more expensive code on a number of platforms, which might cause a performance regression for some of the other percpu-rwsem users.

peterz@infradead.org	23870f1227	locking/lockdep: Fix "USED" <- "IN-NMI" inversions ... During the LPC RCU BoF Paul asked how come the "USED" <- "IN-NMI" detector doesn't trip over rcu_read_lock()'s lockdep annotation. Looking into this I found a very embarrasing typo in verify_lock_unused(): - if (!(class->usage_mask & LOCK_USED)) + if (!(class->usage_mask & LOCKF_USED)) fixing that will indeed cause rcu_read_lock() to insta-splat :/ The above typo means that instead of testing for: 0x100 (1 << LOCK_USED), we test for 8 (LOCK_USED), which corresponds to (1 << LOCK_ENABLED_HARDIRQ). So instead of testing for _any_ used lock, it will only match any lock used with interrupts enabled. The rcu_read_lock() annotation uses .check=0, which means it will not set any of the interrupt bits and will thus never match. In order to properly fix the situation and allow rcu_read_lock() to correctly work, split LOCK_USED into LOCK_USED and LOCK_USED_READ and by having .read users set USED_READ and test USED, pure read-recursive locks are permitted.

Boqun Feng	f611e8cf98	lockdep: Take read/write status in consideration when generate chainkey ... Currently, the chainkey of a lock chain is a hash sum of the class_idx of all the held locks, the read/write status are not taken in to consideration while generating the chainkey. This could result into a problem, if we have: P1() { read_lock(B); lock(A); } P2() { lock(A); read_lock(B); } P3() { lock(A); write_lock(B); } , and P1(), P2(), P3() run one by one. And when running P2(), lockdep detects such a lock chain A -> B is not a deadlock, then it's added in the chain cache, and then when running P3(), even if it's a deadlock, we could miss it because of the hit of chain cache. This could be confirmed by self testcase "chain cached mixed R-L/L-W ". To resolve this, we use concept "hlock_id" to generate the chainkey, the hlock_id is a tuple (hlock->class_idx, hlock->read), which fits in a u16 type. With this, the chainkeys are different is the lock sequences have the same locks but different read/write status. Besides, since we use "hlock_id" to generate chainkeys, the chain_hlocks array now store the "hlock_id"s rather than lock_class indexes.

Currently, in safe->unsafe detection, lockdep misses the fact that a LOCK_ENABLED_IRQ_*_READ usage and a LOCK_USED_IN_IRQ_*_READ usage may cause deadlock too, for example: P1 P2 <irq disabled> write_lock(l1); <irq enabled> read_lock(l2); write_lock(l2); <in irq> read_lock(l1); Actually, all of the following cases may cause deadlocks: LOCK_USED_IN_IRQ_* -> LOCK_ENABLED_IRQ_* LOCK_USED_IN_IRQ_*_READ -> LOCK_ENABLED_IRQ_* LOCK_USED_IN_IRQ_* -> LOCK_ENABLED_IRQ_*_READ LOCK_USED_IN_IRQ_*_READ -> LOCK_ENABLED_IRQ_*_READ To fix this, we need to 1) change the calculation of exclusive_mask() so that READ bits are not dropped and 2) always call usage() in mark_lock_irq() to check usage deadlocks, even when the new usage of the lock is READ.

Boqun Feng	68e3056785	lockdep: Adjust check_redundant() for recursive read change ... check_redundant() will report redundancy if it finds a path could replace the about-to-add dependency in the BFS search. With recursive read lock changes, we certainly need to change the match function for the check_redundant(), because the path needs to match not only the lock class but also the dependency kinds. For example, if the about-to-add dependency @prev -> @next is A -(SN)-> B, and we find a path A -(S*)-> .. -(*R)->B in the dependency graph with __bfs() (for simplicity, we can also say we find an -(SR)-> path from A to B), we can not replace the dependency with that path in the BFS search. Because the -(SN)-> dependency can make a strong path with a following -(S*)-> dependency, however an -(SR)-> path cannot. Further, we can replace an -(SN)-> dependency with a -(EN)-> path, that means if we find a path which is stronger than or equal to the about-to-add dependency, we can report the redundancy. By "stronger", it means both the start and the end of the path are not weaker than the start and the end of the dependency (E is "stronger" than S and N is "stronger" than R), so that we can replace the dependency with that path. To make sure we find a path whose start point is not weaker than the about-to-add dependency, we use a trick: the ->only_xr of the root (start point) of __bfs() is initialized as @prev-> == 0, therefore if @prev is E, __bfs() will pick only -(E*)-> for the first dependency, otherwise, __bfs() can pick -(E*)-> or -(S*)-> for the first dependency. To make sure we find a path whose end point is not weaker than the about-to-add dependency, we replace the match function for __bfs() check_redundant(), we check for the case that either @next is R (anything is not weaker than it) or the end point of the path is N (which is not weaker than anything).

Boqun Feng	9de0c9bbce	lockdep: Support deadlock detection for recursive read locks in check_noncircular() ... Currently, lockdep only has limit support for deadlock detection for recursive read locks. This patch support deadlock detection for recursive read locks. The basic idea is: We are about to add dependency B -> A in to the dependency graph, we use check_noncircular() to find whether we have a strong dependency path A -> .. -> B so that we have a strong dependency circle (a closed strong dependency path): A -> .. -> B -> A , which doesn't have two adjacent dependencies as -(*R)-> L -(S*)->. Since A -> .. -> B is already a strong dependency path, so if either B -> A is -(E*)-> or A -> .. -> B is -(*N)->, the circle A -> .. -> B -> A is strong, otherwise not. So we introduce a new match function hlock_conflict() to replace the class_equal() for the deadlock check in check_noncircular().

Boqun Feng	6971c0f345	lockdep: Extend __bfs() to work with multiple types of dependencies ... Now we have four types of dependencies in the dependency graph, and not all the pathes carry real dependencies (the dependencies that may cause a deadlock), for example: Given lock A and B, if we have: CPU1 CPU2 ============= ============== write_lock(A); read_lock(B); read_lock(B); write_lock(A); (assuming read_lock(B) is a recursive reader) then we have dependencies A -(ER)-> B, and B -(SN)-> A, and a dependency path A -(ER)-> B -(SN)-> A. In lockdep w/o recursive locks, a dependency path from A to A means a deadlock. However, the above case is obviously not a deadlock, because no one holds B exclusively, therefore no one waits for the other to release B, so who get A first in CPU1 and CPU2 will run non-blockingly. As a result, dependency path A -(ER)-> B -(SN)-> A is not a real/strong dependency that could cause a deadlock. From the observation above, we know that for a dependency path to be real/strong, no two adjacent dependencies can be as -(*R)-> -(S*)->. Now our mission is to make __bfs() traverse only the strong dependency paths, which is simple: we record whether we only have -(*R)-> for the previous lock_list of the path in lock_list::only_xr, and when we pick a dependency in the traverse, we 1) filter out -(S*)-> dependency if the previous lock_list only has -(*R)-> dependency (i.e. ->only_xr is true) and 2) set the next lock_list::only_xr to true if we only have -(*R)-> left after we filter out dependencies based on 1), otherwise, set it to false. With this extension for __bfs(), we now need to initialize the root of __bfs() properly (with a correct ->only_xr), to do so, we introduce some helper functions, which also cleans up a little bit for the __bfs() root initialization code.

Boqun Feng	3454a36d6a	lockdep: Introduce lock_list::dep ... To add recursive read locks into the dependency graph, we need to store the types of dependencies for the BFS later. There are four types of dependencies: * Exclusive -> Non-recursive dependencies: EN e.g. write_lock(prev) held and try to acquire write_lock(next) or non-recursive read_lock(next), which can be represented as "prev -(EN)-> next" * Shared -> Non-recursive dependencies: SN e.g. read_lock(prev) held and try to acquire write_lock(next) or non-recursive read_lock(next), which can be represented as "prev -(SN)-> next" * Exclusive -> Recursive dependencies: ER e.g. write_lock(prev) held and try to acquire recursive read_lock(next), which can be represented as "prev -(ER)-> next" * Shared -> Recursive dependencies: SR e.g. read_lock(prev) held and try to acquire recursive read_lock(next), which can be represented as "prev -(SR)-> next" So we use 4 bits for the presence of each type in lock_list::dep.

Boqun Feng	d563bc6ead	lockdep: Make __bfs() visit every dependency until a match ... Currently, __bfs() will do a breadth-first search in the dependency graph and visit each lock class in the graph exactly once, so for example, in the following graph: A ---------> B | ^ | | +----------> C a __bfs() call starts at A, will visit B through dependency A -> B and visit C through dependency A -> C and that's it, IOW, __bfs() will not visit dependency C -> B. This is OK for now, as we only have strong dependencies in the dependency graph, so whenever there is a traverse path from A to B in __bfs(), it means A has strong dependencies to B (IOW, B depends on A strongly). So no need to visit all dependencies in the graph. However, as we are going to add recursive-read lock into the dependency graph, as a result, not all the paths mean strong dependencies, in the same example above, dependency A -> B may be a weak dependency and traverse A -> C -> B may be a strong dependency path. And with the old way of __bfs() (i.e. visiting every lock class exactly once), we will miss the strong dependency path, which will result into failing to find a deadlock. To cure this for the future, we need to find a way for __bfs() to visit each dependency, rather than each class, exactly once in the search until we find a match. The solution is simple: We used to mark lock_class::lockdep_dependency_gen_id to indicate a class has been visited in __bfs(), now we change the semantics a little bit: we now mark lock_class::lockdep_dependency_gen_id to indicate _all the dependencies_ in its lock_{after,before} have been visited in the __bfs() (note we only take one direction in a __bfs() search). In this way, every dependency is guaranteed to be visited until we find a match. Note: the checks in mark_lock_accessed() and lock_accessed() are removed, because after this modification, we may call these two functions on @source_entry of __bfs(), which may not be the entry in "list_entries" Signed-off-by: Boqun Feng <boqun.feng@gmail.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lkml.kernel.org/r/20200807074238.1632519-5-boqun.feng@gmail.com	2020-08-26 12:42:03 +02:00
