llseek requires ocfs2 inode lock for updating the file size in SEEK_END. because the file size maybe update on another node. This bug can be reproduce the following scenario: at first, we dd a test fileA, the file size is 10k. on NodeA: --------- 1) open the test fileA, lseek the end of file. and print the position. 2) close the test fileA on NodeB: 1) open the test fileA, append the 5k data to test FileA. 2) lseek the end of file. and print the position. 3) close file. At first we run the test program1 on NodeA , the result is 10k. And then run the test program2 on NodeB, the result is 15k. At last, we run the test program1 on NodeA again, the result is 10k. After applying this patch the three step result is 15k. test result: 1000000 times lseek call; index lseek with inode lock (unit:us) lseek without inode lock (unit:us) 1 1168162 555383 2 1168011 549504 3 1170538 549396 4 1170375 551685 5 1170444 556719 6 1174364 555307 7 1163294 551552 8 1170080 549350 9 1162464 553700 10 1165441 552594 avg 1168317 552519 avg with lock - avg without lock = 615798 (avg with lock - avg without lock)/1000000=0.615798 us Signed-off-by:

The following patches are reverted in this patch because these patches caused performance regression in the remote unlink() calls. ea455f8a - ocfs2: Push out dropping of dentry lock to ocfs2_wq f7b1aa69 - ocfs2: Fix deadlock on umount 5fd13189 - ocfs2: Don't oops in ocfs2_kill_sb on a failed mount Previous patches in this series removed the possible deadlocks from downconvert thread so the above patches shouldn't be needed anymore. The regression is caused because these patches delay the iput() in case of dentry unlocks. This also delays the unlocking of the open lockres. The open lockresource is required to test if the inode can be wiped from disk or not. When the deleting node does not get the open lock, it marks it as orphan (even though it is not in use by another node/process) and causes a journal checkpoint. This delays operations following the inode eviction. This also moves the inode to the orphaned inode which further causes more I/O and a lot of unneccessary orphans. The following script can be used to generate the load causing issues: declare -a create declare -a remove declare -a iterations=(1 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 16384) unique="`mktemp -u XXXXX`" script="/tmp/idontknow-${unique}.sh" cat <<EOF > "${script}" for n in {1..8}; do mkdir -p test/dir\${n} eval touch test/dir\${n}/foo{1.."\$1"} done EOF chmod 700 "${script}" function fcreate () { exec 2>&1 /usr/bin/time --format=%E "${script}" "$1" } function fremove () { exec 2>&1 /usr/bin/time --format=%E ssh node2 "cd `pwd`; rm -Rf test*" } function fcp () { exec 2>&1 /usr/bin/time --format=%E ssh node3 "cd `pwd`; cp -R test test.new" } echo ------------------------------------------------- echo "| # files | create #s | copy #s | remove #s |" echo ------------------------------------------------- for ((x=0; x < ${#iterations[*]} ; x++)) do create[$x]="`fcreate ${iterations[$x]}`" copy[$x]="`fcp ${iterations[$x]}`" remove[$x]="`fremove`" printf "| %8d | %9s | %9s | %9s |\n" ${iterations[$x]} ${create[$x]} ${copy[$x]} ${remove[$x]} done rm "${script}" echo "------------------------" Signed-off-by:

If we are dropping last inode reference from downconvert thread, we will end up calling ocfs2_mark_lockres_freeing() which can block if the lock we are freeing is queued thus creating an A-A deadlock. Luckily, since we are the downconvert thread, we can immediately dequeue the lock and thus avoid waiting in this case. Signed-off-by:

This is a part of the nocontrold feature which was incorporated sometime back. This is required for backward compatibility of the tools, specifically the scenario where the tools with recovery callback is used with a kernel not using the recovery callbacks (older kernel + newer tools). The tools look for this file to understand if the kernel supports DLM recovery callbacks. For kernels which support recovery callbacks but will miss this patch, ocfs2 will continue to use the older API and would still be able to mount the filesystem.

There is a race window in dlm_do_recovery() between dlm_remaster_locks() and dlm_reset_recovery() when the recovery master nearly finish the recovery process for a dead node. After the master sends FINALIZE_RECO message in dlm_remaster_locks(), another node may become the recovery master for another dead node, and then send the BEGIN_RECO message to all the nodes included the old master, in the handler of this message dlm_begin_reco_handler() of old master, dlm->reco.dead_node and dlm->reco.new_master will be set to the second dead node and the new master, then in dlm_reset_recovery(), these two variables will be reset to default value. This will cause new recovery master can not finish the recovery process and hung, at last the whole cluster will hung for recovery. old recovery master: new recovery master: dlm_remaster_locks() become recovery master for another dead node. dlm_send_begin_reco_message() dlm_begin_reco_handler() { if (dlm->reco.state & DLM_RECO_STATE_FINALIZE) { return -EAGAIN; } dlm_set_reco_master(dlm, br->node_idx); dlm_set_reco_dead_node(dlm, br->dead_node); } dlm_reset_recovery() { dlm_set_reco_dead_node(dlm, O2NM_INVALID_NODE_NUM); dlm_set_reco_master(dlm, O2NM_INVALID_NODE_NUM); } will hang in dlm_remaster_locks() for request dlm locks info Before send FINALIZE_RECO message, recovery master should set DLM_RECO_STATE_FINALIZE for itself and clear it after the recovery done, this can break the race windows as the BEGIN_RECO messages will not be handled before DLM_RECO_STATE_FINALIZE flag is cleared. A similar race may happen between new recovery master and normal node which is in dlm_finalize_reco_handler(), also fix it. Signed-off-by:Junxiao Bi <junxiao.bi@oracle.com> Reviewed-by:

This issue was introduced by commit 800deef3 ("ocfs2: use list_for_each_entry where benefical") in 2007 where it replaced list_for_each with list_for_each_entry. The variable "lock" will point to invalid data if "tmpq" list is empty and a panic will be triggered due to this. Sunil advised reverting it back, but the old version was also not right. At the end of the outer for loop, that list_for_each_entry will also set "lock" to an invalid data, then in the next loop, if the "tmpq" list is empty, "lock" will be an stale invalid data and cause the panic. So reverting the list_for_each back and reset "lock" to NULL to fix this issue. Another concern is that this seemes can not happen because the "tmpq" list should not be empty. Let me describe how. old lock resource owner(node 1): migratation target(node 2): image there's lockres with a EX lock from node 2 in granted list, a NR lock from node x with convert_type EX in converting list. dlm_empty_lockres() { dlm_pick_migration_target() { pick node 2 as target as its lock is the first one in granted list. } dlm_migrate_lockres() { dlm_mark_lockres_migrating() { res->state |= DLM_LOCK_RES_BLOCK_DIRTY; wait_event(dlm->ast_wq, !dlm_lockres_is_dirty(dlm, res)); //after the above code, we can not dirty lockres any more, // so dlm_thread shuffle list will not run downconvert lock from EX to NR upconvert lock from NR to EX <<< migration may schedule out here, then <<< node 2 send down convert request to convert type from EX to <<< NR, then send up convert request to convert type from NR to <<< EX, at this time, lockres granted list is empty, and two locks <<< in the converting list, node x up convert lock followed by <<< node 2 up convert lock. // will set lockres RES_MIGRATING flag, the following // lock/unlock can not run dlm_lockres_release_ast(dlm, res); } dlm_send_one_lockres() dlm_process_recovery_data() for (i=0; i<mres->num_locks; i++) if (ml->node == dlm->node_num) for (j = DLM_GRANTED_LIST; j <= DLM_BLOCKED_LIST; j++) { list_for_each_entry(lock, tmpq, list) if (lock) break; <<< lock is invalid as grant list is empty. } if (lock->ml.node != ml->node) BUG() >>> crash here } I see the above locks status from a vmcore of our internal bug.

Currently, ocfs2_sync_file grabs i_mutex and forces the current journal transaction to complete. This isn't terribly efficient, since sync_file really only needs to wait for the last transaction involving that inode to complete, and this doesn't require i_mutex. Therefore, implement the necessary bits to track the newest tid associated with an inode, and teach sync_file to wait for that instead of waiting for everything in the journal to commit. Furthermore, only issue the flush request to the drive if jbd2 hasn't already done so. This also eliminates the deadlock between ocfs2_file_aio_write() and ocfs2_sync_file(). aio_write takes i_mutex then calls ocfs2_aiodio_wait() to wait for unaligned dio writes to finish. However, if that dio completion involves calling fsync, then we can get into trouble when some ocfs2_sync_file tries to take i_mutex. Signed-off-by:

There is a problem that waitqueue_active() may check stale data thus miss a wakeup of threads waiting on ip_unaligned_aio. The valid value of ip_unaligned_aio is only 0 and 1 so we can change it to be of type mutex thus the above prolem is avoid. Another benifit is that mutex which works as FIFO is fairer than wake_up_all(). Signed-off-by:

When mounting an ocfs2 volume, it will firstly generate a file /sys/kernel/debug/o2dlm/<uuid>/dlm_state, and then launch the dlm thread. So the following situation will cause a null pointer dereference. dlm_debug_init -> access file dlm_state which will call dlm_state_print -> dlm_launch_thread Move dlm_debug_init after dlm_launch_thread and dlm_launch_recovery_thread can fix this issue.

When invoking syscall handlers on sh32, the saved userspace registers are at the top of the stack. This seems to have been intentional, as it is an easy way to pass r0, r1, ... to the handler as parameters 5, 6, ... It causes problems, however, because the compiler is allowed to generate code for a function which clobbers that function's own parameters. For example, gcc generates the following code for clone: <SyS_clone>: mov.l 8c020714 <SyS_clone+0xc>,r1 ! 8c020540 <do_fork> mov.l r7,@r15 mov r6,r7 jmp @r1 mov #0,r6 nop .word 0x0540 .word 0x8c02 The `mov.l r7,@r15` clobbers the saved value of r0 passed from userspace. For most system calls, this might not be a problem, because we'll be overwriting r0 with the return value anyway. But in the case of clone, copy_thread will need the original value of r0 if the CLONE_SETTLS flag was specified. The first patch in this series fixes this issue for system calls by pushing to the stack and extra copy of r0-r2 before invoking the handler. We discard this copy before restoring the userspace registers, so it is not a problem if they are clobbered. Exception handlers also receive the userspace register values in a similar manner, and may hit the same problem. The second patch removes the do_fpu_error handler, which looks susceptible to this problem and which, as far as I can tell, has not been used in some time. The third patch addresses other exception handlers. This patch (of 3): The userspace registers are stored at the top of the stack when the syscall handler is invoked, which allows r0-r2 to act as parameters 5-7. Parameters passed on the stack may be clobbered by the syscall handler. The solution is to push an extra copy of the registers which might be used as syscall parameters to the stack, so that the authoritative set of saved register values does not get clobbered. A few system call handlers are also updated to get the userspace registers using current_pt_regs() instead of from the stack. Signed-off-by: -

Recent increased use of typeof() throughout the tree resulted in a number of symbols (25 in a typical distro config of ours) not getting a proper CRC calculated for them anymore, due to the parser in genksyms not coping with several of these uses (interestingly in the majority of [if not all] cases the problem is due to the use of typeof() in code preceding a certain export, not in the declaration/definition of the exported function/object itself; I wasn't able to find a way to address this more general parser shortcoming). The use of parameter_declaration is a little more relaxed than would be ideal (permitting not just a bare type specification, but also one with identifier), but since the same code is being passed through an actual compiler, there's no apparent risk of allowing through any broken code. Otoh using parameter_declaration instead of the ad hoc "decl_specifier_seq '*'" / "decl_specifier_seq" pair allows all types to be handled rather than just plain ones and pointers to plain ones.

Move code moving event structure to access_list from copy_event_to_user() to fanotify_read() where it is more logical (so that we can immediately see in the main loop that we either move the event to a different list or free it). Also move special error handling for permission events from copy_event_to_user() to the main loop to have it in one place with error handling for normal events. This makes copy_event_to_user() really only copy the event to user without any side effects. Signed-off-by:

Jan Kara authored
Currently, fanotify creates new structure to track the fact that permission event has been reported to userspace and someone is waiting for a response to it. As event structures are now completely in the hands of each notification framework, we can use the event structure for this tracking instead of allocating a new structure. Since this makes the event structures for normal events and permission events even more different and the structures have different lifetime rules, we split them into two separate structures (where permission event structure contains the structure for a normal event). This makes normal events 8 bytes smaller and the code a tad bit cleaner. [akpm@linux-foundation.org: fix build] Signed-off-by:

The prepare_for_access_response() function checks whether group->fanotify_data.bypass_perm is set. However this test can never be true because prepare_for_access_response() is called only from fanotify_read() which means fanotify group is alive with an active fd while bypass_perm is set from fanotify_release() when all file descriptors pointing to the group are closed and the group is going away.

In the presence of memoryless nodes, numa_node_id() will return the current CPU's NUMA node, but that may not be where we expect to allocate from memory from. Instead, we should rely on the fallback code in the memory allocator itself, by using NUMA_NO_NODE. Also, when calling kthread_create_on_node(), use the nearest node with memory to the cpu in question, rather than the node it is running on. Signed-off-by:

After commit 839a8e86 ("writeback: replace custom worker pool implementation with unbound workqueue") when device is removed while we are writing to it we crash in bdi_writeback_workfn() -> set_worker_desc() because bdi->dev is NULL. This can happen because even though bdi_unregister() cancels all pending flushing work, nothing really prevents new ones from being queued from balance_dirty_pages() or other places. Fix the problem by clearing BDI_registered bit in bdi_unregister() and checking it before scheduling of any flushing work. Fixes: 839a8e86Reviewed-by:

bdi_wakeup_thread_delayed() used the mod_delayed_work() function to schedule work to writeback dirty inodes. The problem with this is that it can delay work that is scheduled for immediate execution, such as the work from sync_inodes_sb(). This can happen since mod_delayed_work() can now steal work from a work_queue. This fixes the problem by using queue_delayed_work() instead. This is a regression caused by commit 839a8e86 ("writeback: replace custom worker pool implementation with unbound workqueue"). The reason that this causes a problem is that laptop-mode will change the delay, dirty_writeback_centisecs, to 60000 (10 minutes) by default. In the case that bdi_wakeup_thread_delayed() races with sync_inodes_sb(), sync will be stopped for 10 minutes and trigger a hung task. Even if dirty_writeback_centisecs is not long enough to cause a hung task, we still don't want to delay sync for that long. We fix the problem by using queue_delayed_work() when we want to schedule writeback sometime in future. This function doesn't change the timer if it is already armed. For the same reason, we also change bdi_writeback_workfn() to immediately queue the work again in the case that the work_list is not empty. The same problem can happen if the sync work is run on the rescue worker. [jack@suse.cz: update changelog, add comment, use bdi_wakeup_thread_delayed()] Signed-off-by:
