* cluster/afr: Remove backward compatibility for locks with v1Pranith Kumar K2016-12-072-69/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have cascading locks with same lk-owner there is a possibility for a deadlock to happen. One example is as follows: self-heal takes a lock in data-domain for big name with 256 chars of "aaaa...a" and starts heal in a 3-way replication when brick-0 is offline and healing from brick-1 to brick-2 is in progress. So this lock is active on brick-1 and brick-2. Now brick-0 comes online and an operation wants to take full lock and the lock is granted at brick-0 and it is waiting for lock on brick-1. As part of entry healing it takes full locks on all the available bricks and then proceeds with healing the entry. Now this lock will start waiting on brick-0 because some other operation already has a granted lock on it. This leads to a deadlock. Operation is waiting for unlock on "aaaa..." by heal where as heal is waiting for the operation to unlock on brick-0. Initially I thought this is happening because healing is trying to take a lock on all the available bricks instead of just the bricks that are participating in heal. But later realized that same kind of deadlock can happen if a brick goes down after the heal starts but comes back before it completes. So the essential problem is the cascading locks with same lk-owner which were added for backward compatibility with afr-v1 which can be safely removed now that versions with afr-v1 are already EOL. This patch removes the compatibility with v1 which requires cascading locks with same lk-owner. In the next version we can make locking-scheme option a dummy and switch completely to v2.

* cluster/afr: Serialize conflicting locks on all subvolsPranith Kumar K2016-12-062-33/+53
| | | | | | | | | | | | | | | | | | | | | | | Problem: 1) When a blocking lock is issued and the parallel lock phase fails on all subvolumes with EAGAIN, it is not switching to serialized locking phase. 2) When quorum is enabled and locks fail partially it is better to give errno returned by brick rather than the default quorum errno. Fix: Handled this error case and changed op_errno to reflect the actual errno in case of quorum error.

* rpc: fix for race between rpc and protocol/clientRajesh Joseph2016-12-052-40/+59
| | | | | | | | | | | | | | | | | | | | | | | | It is possible that the notification thread which notifies protocol/client layer about the disconnection is put to sleep and meanwhile, a fuse thread or a timer thread initiates and completes reconnection to the brick. The notification thread is then woken up and protocol/client layer updates its flags to indicate that network is disconnected. No reconnection is initiated because reconnection is rpc-lib layer's responsibility and its flags indicate that connection is connected. Fix: Serialize connect and disconnect notify Credit: Raghavendra Talur <rtalur@redhat.com> Change-Id: I8ff5d1a3283b47f5c26848a42016a40bc34ffc1d BUG: 1386626 Signed-off-by: Rajesh Joseph <rjoseph@redhat.com> Reviewed-on: http://review.gluster.org/15916 Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra Talur <rtalur@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>

This infinite loop can cause increased consumption of memory due to: 1) dht_lookup_directory assigns a new layout to local->layout unconditionally 2) Most of the functions in this loop do a stack_wind of various fops.

This can lead to dead lock if we consume all the epoll threads. In general any call-back function executed in epoll thread should not call any blocking call which waits on a network reply either directly or indirectly, e.g. syncop functions should not be called in these threads. As a fix we should not wait for migration in the call-back path.

RCA: ==== In certain cases, ioc_readv() issues STACK_WIND_TAIL() instead of STACK_WIND(). One such case is when inode_ctx for that file is not present (can happen if readdirp was called, and populates md-cache and serves all the lookups from cache). Consider the following graph: ... io-cache (parent) | readdir-ahead | read-ahead ... Below is the code snippet of ioc_readv calling STACK_WIND_TAIL: ioc_readv() { ... if (!inode_ctx) STACK_WIND_TAIL (frame, FIRST_CHILD (frame->this), FIRST_CHILD (frame->this)->fops->readv, fd, size, offset, flags, xdata); /* Ideally, this stack_wind should wind to readdir-ahead:readv() but it winds to read-ahead:readv(). See below for explaination. */ ... } STACK_WIND_TAIL (frame, obj, fn, ...) { frame->this = obj; /* for the above mentioned graph, frame->this will be readdir-ahead * frame->this = FIRST_CHILD (frame->this) i.e. readdir-ahead, which * is as expected */ ... THIS = obj; /* THIS will be read-ahead instead of readdir-ahead!, as obj expands * to "FIRST_CHILD (frame->this)" and frame->this was pointing * to readdir-ahead in the previous statement. */ ... fn (frame, obj, params); /* fn will call read-ahead:readv() instead of readdir-ahead:readv()! * as fn expands to "FIRST_CHILD (frame->this)->fops->readv" and * frame->this was pointing ro readdir-ahead in the first statement */ ... } Thus, the readdir-ahead's readv() implementation will be skipped, and ra_readv() will be called with frame->this = "readdir-ahead" and this = "read-ahead". This can lead to corruption / hang / other problems. But in this perticular case, when 'frame->this' and 'this' passed to ra_readv() doesn't match, it causes ra_readv() to call ra_readv() again!. Thus the logic of read-ahead readv() falls apart and leads to hang. Solution: ========= Modify STACK_WIND_TAIL() as: STACK_WIND_TAIL (frame, obj, fn, ...) { next_xl = obj /* resolve obj as the variables passed in obj macro can be overwritten in the further instrucions */ next_xl_fn = fn /* resolve fn and store in a tmp variable, before modifying any variables */ frame->this = next_xl; ... THIS = next_xl; ... next_xl_fn (frame, next_xl, params); ... } As a part of http://review.gluster.org/15901/ the caller io-cache was fixed.

* cluster/afr: Fix deadlock due to compound fopsKrutika Dhananjay2016-11-261-14/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an afr data transaction is eligible for using eager-lock, this information is represented in local->transaction.eager_lock_on. However, if non-blocking inodelk attempt (which is a full lock) fails, AFR falls back to blocking locks which are range locks. At this point, local->transaction.eager_lock[] per brick is reset but local->transaction.eager_lock_on is still true. When AFR decides to compound post-op and unlock, it is after confirming that the transaction did not use eager lock (well, except for a small bug where local->transaction.locks_acquired[] is not considered). But within afr_post_op_unlock_do(), afr again incorrectly sets the lock range to full-lock based on local->transaction.eager_lock_on value. This is a bug and can lead to deadlock since the locks acquired were range locks and a full unlock is being sent leading to unlock failure and thereby every other lock request (be it from SHD or other clients or glfsheal) getting blocked forever and the user perceives a hang. FIX: Unconditionally rely on the range locks in inodelk object for unlocking when using compounded post-op + unlock. Big thanks to Pranith for helping with the debugging.

| | | | | | | | | | | | | | | | | | | | | | during crawl If granular name indices are already in existence for a volume, and before they are healed, granular entry heal be disabled, a crawl on indices/xattrop will clear the changelogs on these directories. When their corresponding entry-changes indices are crawled subsequently, if it is found that the directories don't need heal anymore, the granular indices are not cleaned up. This patch fixes that problem by ensuring that the zero-xattrop also deletes the stale indices at the level of index translator.

* io-cache: Fix a read hangPoornima G2016-11-233-6/+163
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: ===== In certain cases, there was no unwind of read from read-ahead xlator, thus resulting in hang. RCA: ==== In certain cases, ioc_readv() issues STACK_WIND_TAIL() instead of STACK_WIND(). One such case is when inode_ctx for that file is not present (can happen if readdirp was called, and populates md-cache and serves all the lookups from cache). Consider the following graph: ... io-cache (parent) | readdir-ahead | read-ahead ... Below is the code snippet of ioc_readv calling STACK_WIND_TAIL: ioc_readv() { ... if (!inode_ctx) STACK_WIND_TAIL (frame, FIRST_CHILD (frame->this), FIRST_CHILD (frame->this)->fops->readv, fd, size, offset, flags, xdata); /* Ideally, this stack_wind should wind to readdir-ahead:readv() but it winds to read-ahead:readv(). See below for explaination. */ ... } STACK_WIND_TAIL (frame, obj, fn, ...) { frame->this = obj; /* for the above mentioned graph, frame->this will be readdir-ahead * frame->this = FIRST_CHILD (frame->this) i.e. readdir-ahead, which * is as expected */ ... THIS = obj; /* THIS will be read-ahead instead of readdir-ahead!, as obj expands * to "FIRST_CHILD (frame->this)" and frame->this was pointing * to readdir-ahead in the previous statement. */ ... fn (frame, obj, params); /* fn will call read-ahead:readv() instead of readdir-ahead:readv()! * as fn expands to "FIRST_CHILD (frame->this)->fops->readv" and * frame->this was pointing ro readdir-ahead in the first statement */ ... } Thus, the readdir-ahead's readv() implementation will be skipped, and ra_readv() will be called with frame->this = "readdir-ahead" and this = "read-ahead". This can lead to corruption / hang / other problems. But in this perticular case, when 'frame->this' and 'this' passed to ra_readv() doesn't match, it causes ra_readv() to call ra_readv() again!. Thus the logic of read-ahead readv() falls apart and leads to hang. Solution: ========= Ideally, STACK_WIND_TAIL() should be modified as: STACK_WIND_TAIL (frame, obj, fn, ...) { next_xl = obj /* resolve obj as the variables passed in obj macro can be overwritten in the further instrucions */ next_xl_fn = fn /* resolve fn and store in a tmp variable, before modifying any variables */ frame->this = next_xl; ... THIS = next_xl; ... next_xl_fn (frame, next_xl, params); ... } But for this solution, knowing the type of variable 'next_xl_fn' is a challenge and is not easy. Hence just modifying all the existing callers to pass "FIRST_CHILD (this)" as obj, instead of "FIRST_CHILD (frame->this)".

* glusterd: fix few events generationAtin Mukherjee2016-11-236-8/+17
| | | | | | | | | | | | | | | | | | | | | This patch does the following: 1. Generate PEER_REJECT event if the peer add request is from an unknown peer during peer handshaking. 2. EVENT_COMPARE_FRIEND_VOLUME_FAILED should be generated based on status code, not ret. 3. Add EVENT_BRICKPATH_RESOLVE_FAILED event in case glusterd fails to resolve bricks, this is mainly at restore path. 4. Remove EVENT_BRICKS_START_FAILED event as we already have EVENT_BRICK_START_FAILED Change-Id: I90e5bc4a331166d0bb3554eb2ec9df2526837a1d BUG: 1397424 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-on: http://review.gluster.org/15903 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Samikshan Bairagya <samikshan@gmail.com>
