When the recovery master is down, the owner of $RECOVERY calls dlm_do_local_recovery_cleanup() to prune any $RECOVERY entries for dead nodes. The lock is in the granted list and the refcount must be 2. We should put twice to remove this lock. Otherwise, it will lead to a memory leak.

In ocfs2_link(), the parent directory inode passed to function ocfs2_lookup_ino_from_name() is wrong. Parameter dir is the parent of new_dentry not old_dentry. We should get old_dir from old_dentry and lookup old_dentry in old_dir in case another node remove the old dentry. With this change, hard linking works again, when paths are relative with at least one subdirectory. This is how the problem was reproducable: # mkdir a # mkdir b # touch a/test # ln a/test b/test ln: failed to create hard link `b/test' => `a/test': No such file or directory However when creating links in the same dir, it worked well. Now the link gets created.

For buffer write, page lock will be got in write_begin and released in write_end, in ocfs2_write_end_nolock(), before it unlock the page in ocfs2_free_write_ctxt(), it calls ocfs2_run_deallocs(), this will ask for the read lock of journal->j_trans_barrier. Holding page lock and ask for journal->j_trans_barrier breaks the locking order. This will cause a deadlock with journal commit threads, ocfs2cmt will get write lock of journal->j_trans_barrier first, then it wakes up kjournald2 to do the commit work, at last it waits until done. To commit journal, kjournald2 needs flushing data first, it needs get the cache page lock. Since some ocfs2 cluster locks are holding by write process, this deadlock may hung the whole cluster. unlock pages before ocfs2_run_deallocs() can fix the locking order, also put unlock before ocfs2_commit_trans() to make page lock is unlocked before j_trans_barrier to preserve unlocking order.

When running ocfs2 test suite multiple nodes reflink stress test, for a 4 nodes cluster, every unlink() for refcounted file needs about 700s. The slow unlink is caused by the contention of refcount tree lock since all nodes are unlink files using the same refcount tree. When the unlinking file have many extents(over 1600 in our test), most of the extents has refcounted flag set. In ocfs2_commit_truncate(), it will execute the following call trace for every extents. This means it needs get and released refcount tree lock about 1600 times. And when several nodes are do this at the same time, the performance will be very low. ocfs2_remove_btree_range() -- ocfs2_lock_refcount_tree() ---- ocfs2_refcount_lock() ------ __ocfs2_cluster_lock() ocfs2_refcount_lock() is costly, move it to ocfs2_commit_truncate() to do lock/unlock once can improve a lot performance.

ocfs2_readpages() use nonblocking flag to avoid page lock inversion. It will trigger cluster hang because that flag OCFS2_LOCK_UPCONVERT_FINISHING is not cleared if nonblocking lock cannot be granted at once. The flag would prevent dc thread from downconverting. So other nodes cannot acheive this lockres for ever. So we should not set OCFS2_LOCK_UPCONVERT_FINISHING when receiving ast if nonblocking lock had already returned.

Filesize is not a good indication that the file needs to be synced. An example where this breaks is: 1. Open the file in O_SYNC|O_RDWR 2. Read a small portion of the file (say 64 bytes) 3. Lseek to starting of the file 4. Write 64 bytes If the node crashes, it is not written out to disk because this was not committed in the journal and the other node which reads the file after recovery reads stale data (even if the write on the other node was successful) Signed-off-by: NGoldwyn Rodrigues <rgoldwyn@suse.de> Reviewed-by: NMark Fasheh <mfasheh@suse.de> Cc: Joel Becker <jlbec@evilplan.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Set nn_persistent_error to -ENOTCONN will stop reconnect since the "stop" condition in o2net_start_connect() will be true. stop = (nn->nn_sc || (nn->nn_persistent_error && (nn->nn_persistent_error != -ENOTCONN || timeout == 0))); This will make connection never be established if the first connection request is lost. Set nn_persistent_error to 0 when connect expired to fix this. With this changes, dlm will not be waken up when connect expired, this is OK since dlm depends on network, dlm can do nothing in this case if waken up. Let it wait there for network recover and connect built again to continue.

Node A sends master query request to node B which is the master. At this time lockres happens to be on purgelist. dlm_master_request_handler gets the dlm spinlock, finds the resource and releases the dlm spin lock. Right at this dlm_thread on this node could purge the lockres. dlm_master_request_handler can then acquire lockres spinlock and reply to Node A that node B is the master even though lockres on node B is purged. The above scenario will now make node A falsely think node B is the master which is inconsistent. Further if another node C tries to master the same resource, every node will respond they are not the master. Node C then masters the resource and sends assert master to all nodes. This will now make node A crash with the following message. dlm_assert_master_handler:1831 ERROR: DIE! Mastery assert from 9, but current owner is 10!

The kernel used to contain two functions for length-delimited, case-insensitive string comparison, strnicmp with correct semantics and a slightly buggy strncasecmp. The latter is the POSIX name, so strnicmp was renamed to strncasecmp, and strnicmp made into a wrapper for the new strncasecmp to avoid breaking existing users. To allow the compat wrapper strnicmp to be removed at some point in the future, and to avoid the extra indirection cost, do s/strnicmp/strncasecmp/g.

Fix a deadlock problem caused by direct memory reclaim in o2net_wq. The situation is as follows: 1) Receive a connect message from another node, node queues a work_struct o2net_listen_work. 2) o2net_wq processes this work and call the following functions: o2net_wq -> o2net_accept_one -> sock_create_lite -> sock_alloc() -> kmem_cache_alloc with GFP_KERNEL -> ____cache_alloc_node ->__alloc_pages_nodemask -> do_try_to_free_pages -> shrink_slab -> evict -> ocfs2_evict_inode -> ocfs2_drop_lock -> dlmunlock -> o2net_send_message_vec then o2net_wq wait for the unlock reply from master. 3) tcp layer received the reply, call o2net_data_ready() and queue sc_rx_work, waiting o2net_wq to process this work. 4) o2net_wq is a single thread workqueue, it process the work one by one. Right now it is still doing o2net_listen_work and cannot handle sc_rx_work. so we deadlock. Junxiao Bi's patch "mm: clear __GFP_FS when PF_MEMALLOC_NOIO is set" (http://ozlabs.org/~akpm/mmots/broken-out/mm-clear-__gfp_fs-when-pf_memalloc_noio-is-set.patch) clears __GFP_FS in memalloc_noio_flags() besides __GFP_IO. We use memalloc_noio_save() to set process flag PF_MEMALLOC_NOIO so that all allocations done by this process are done as if GFP_NOIO was specified.

For commit ocfs2 journal, ocfs2 journal thread will acquire the mutex osb->journal->j_trans_barrier and wake up jbd2 commit thread, then it will wait until jbd2 commit thread done. In order journal mode, jbd2 needs flushing dirty data pages first, and this needs get page lock. So osb->journal->j_trans_barrier should be got before page lock. But ocfs2_write_zero_page() and ocfs2_write_begin_inline() obey this locking order, and this will cause deadlock and hung the whole cluster. One deadlock catched is the following: PID: 13449 TASK: ffff8802e2f08180 CPU: 31 COMMAND: "oracle" #0 [ffff8802ee3f79b0] __schedule at ffffffff8150a524 #1 [ffff8802ee3f7a58] schedule at ffffffff8150acbf #2 [ffff8802ee3f7a68] rwsem_down_failed_common at ffffffff8150cb85 #3 [ffff8802ee3f7ad8] rwsem_down_read_failed at ffffffff8150cc55 #4 [ffff8802ee3f7ae8] call_rwsem_down_read_failed at ffffffff812617a4 #5 [ffff8802ee3f7b50] ocfs2_start_trans at ffffffffa0498919 [ocfs2] #6 [ffff8802ee3f7ba0] ocfs2_zero_start_ordered_transaction at ffffffffa048b2b8 [ocfs2] #7 [ffff8802ee3f7bf0] ocfs2_write_zero_page at ffffffffa048e9bd [ocfs2] #8 [ffff8802ee3f7c80] ocfs2_zero_extend_range at ffffffffa048ec83 [ocfs2] #9 [ffff8802ee3f7ce0] ocfs2_zero_extend at ffffffffa048edfd [ocfs2] #10 [ffff8802ee3f7d50] ocfs2_extend_file at ffffffffa049079e [ocfs2] #11 [ffff8802ee3f7da0] ocfs2_setattr at ffffffffa04910ed [ocfs2] #12 [ffff8802ee3f7e70] notify_change at ffffffff81187d29 #13 [ffff8802ee3f7ee0] do_truncate at ffffffff8116bbc1 #14 [ffff8802ee3f7f50] sys_ftruncate at ffffffff8116bcbd #15 [ffff8802ee3f7f80] system_call_fastpath at ffffffff81515142 RIP: 00007f8de750c6f7 RSP: 00007fffe786e478 RFLAGS: 00000206 RAX: 000000000000004d RBX: ffffffff81515142 RCX: 0000000000000000 RDX: 0000000000000200 RSI: 0000000000028400 RDI: 000000000000000d RBP: 00007fffe786e040 R8: 0000000000000000 R9: 000000000000000d R10: 0000000000000000 R11: 0000000000000206 R12: 000000000000000d R13: 00007fffe786e710 R14: 00007f8de70f8340 R15: 0000000000028400 ORIG_RAX: 000000000000004d CS: 0033 SS: 002b crash64> bt PID: 7610 TASK: ffff88100fd56140 CPU: 1 COMMAND: "ocfs2cmt" #0 [ffff88100f4d1c50] __schedule at ffffffff8150a524 #1 [ffff88100f4d1cf8] schedule at ffffffff8150acbf #2 [ffff88100f4d1d08] jbd2_log_wait_commit at ffffffffa01274fd [jbd2] #3 [ffff88100f4d1d98] jbd2_journal_flush at ffffffffa01280b4 [jbd2] #4 [ffff88100f4d1dd8] ocfs2_commit_cache at ffffffffa0499b14 [ocfs2] #5 [ffff88100f4d1e38] ocfs2_commit_thread at ffffffffa0499d38 [ocfs2] #6 [ffff88100f4d1ee8] kthread at ffffffff81090db6 #7 [ffff88100f4d1f48] kernel_thread_helper at ffffffff81516284 crash64> bt PID: 7609 TASK: ffff88100f2d4480 CPU: 0 COMMAND: "jbd2/dm-20-86" #0 [ffff88100def3920] __schedule at ffffffff8150a524 #1 [ffff88100def39c8] schedule at ffffffff8150acbf #2 [ffff88100def39d8] io_schedule at ffffffff8150ad6c #3 [ffff88100def39f8] sleep_on_page at ffffffff8111069e #4 [ffff88100def3a08] __wait_on_bit_lock at ffffffff8150b30a #5 [ffff88100def3a58] __lock_page at ffffffff81110687 #6 [ffff88100def3ab8] write_cache_pages at ffffffff8111b752 #7 [ffff88100def3be8] generic_writepages at ffffffff8111b901 #8 [ffff88100def3c48] journal_submit_data_buffers at ffffffffa0120f67 [jbd2] #9 [ffff88100def3cf8] jbd2_journal_commit_transaction at ffffffffa0121372[jbd2] #10 [ffff88100def3e68] kjournald2 at ffffffffa0127a86 [jbd2] #11 [ffff88100def3ee8] kthread at ffffffff81090db6 #12 [ffff88100def3f48] kernel_thread_helper at ffffffff81516284 Signed-off-by: NJunxiao Bi <junxiao.bi@oracle.com> Cc: Mark Fasheh <mfasheh@suse.com> Cc: Joel Becker <jlbec@evilplan.org> Cc: Alex Chen <alex.chen@huawei.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The following case may lead to o2net_wq and o2hb thread deadlock on o2hb_callback_sem. Currently there are 2 nodes say N1, N2 in the cluster. And N2 down, at the same time, N3 tries to join the cluster. So N1 will handle node down (N2) and join (N3) simultaneously. o2hb o2net_wq ->o2hb_do_disk_heartbeat ->o2hb_check_slot ->o2hb_run_event_list ->o2hb_fire_callbacks ->down_write(&o2hb_callback_sem) ->o2net_hb_node_down_cb ->flush_workqueue(o2net_wq) ->o2net_process_message ->dlm_query_join_handler ->o2hb_check_node_heartbeating ->o2hb_fill_node_map ->down_read(&o2hb_callback_sem) No need to take o2hb_callback_sem in dlm_query_join_handler, o2hb_live_lock is enough to protect live node map.

Firing quorum before connection established can cause unexpected node to reboot. Assume there are 3 nodes in the cluster, Node 1, 2, 3. Node 2 and 3 have wrong ip address of Node 1 in cluster.conf and global heartbeat is enabled in the cluster. After the heatbeats are started on these three nodes, Node 1 will reboot due to quorum fencing. It is similar case if Node 1's networking is not ready when starting the global heartbeat. The reboot is not friendly as customer is not fully ready for ocfs2 to work. Fix it by not allowing firing quorum before the connection is established. In this case, ocfs2 will wait until the wrong configuration is fixed or networking is up to continue. Also update the log to guide the user where to check when connection is not built for a long time.

Reduce boilerplate code by using seq_open_private() instead of seq_open() Note that the code in and using sc_common_open() has been quite extensively changed. Not least because there was a latent memory leak in the code as was: if sc_common_open() failed, the previously allocated buffer was not freed.
