* POSIX/xlators: Unused and unchecked value coverity issueyatipadia2019-10-111-2/+2
| | | | | | | | | | | | | | | | | | This patch addresses CID-1274094 and CID-1382354 Problem(1): "ret" was assigned a value which was never used, it was overwritten by 0 and hence has no use. Problem(2): function was called without checking the return value. Solution(1): Removed the assignment and just called the function whose value was being written in ret. Solution(2): There was no need to check for the return value as at the end 0 is returned, so typecasted the return value as void.

* Posix: UNUSED VALUE coverity fixPurna Pavan Chandra Aekkaladevi2019-10-111-2/+0
| | | | | | | | | | | | This patch fixes Coverity issue with CID 1274206 Problem : -1 is assigned to op_ret, but that stored value is overwritten before it can be used. Fix : Removal of the line that assigns -1 to op_ret which has no significance.

* performance/read-ahead: update expected offset before unwinding read responseRaghavendra G2019-10-111-2/+2
| | | | | | | | | | | | | | With the current code there is a window of time between unwinding response to a read request and internal offset is updated to account the read just done. If new sequential read request comes in this time window, it is incorrectly identified as non-sequential read. Fix is to update the file offset to account for a read request before sending back the response to it.

* cluster/afr: Heal entries when there is a source & no healed_sinkskarthik-us2019-10-091-0/+15
| | | | | | | | | | | | | | | | | | | | Problem: In a situation where B1 blames B2, B2 blames B1 and B3 doesn't blame anything for entry heal, heal will not complete even though we have clear source and sinks. This will happen because while doing afr_selfheal_find_direction() only the bricks which are blamed by non-accused bricks are considered as sinks. Later in __afr_selfheal_entry_finalize_source() when it tries to mark all the non-sources as sinks it fails to do so because there won't be any healed_sinks marked, no witness present and there will be a source. Fix: If there is a source and no healed_sinks, then reset all the locked sources to 0 and healed sinks to 1 to do conservative merge.

* afr: support split-brain CLI for replica 3Ravishankar N2019-10-092-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | Ever since we added quorum checks for lookups in afr via commit bd44d59741bb8c0f5d7a62c5b1094179dd0ce8a4, the split-brain resolution commands would not work for replica 3 because there would be no readables for the lookup fop. The argument was that split-brains do not occur in replica 3 but we do see (data/metadata) split-brain cases once in a while which indicate that there are a few bugs/corner cases yet to be discovered and fixed. Fortunately, commit 8016d51a3bbd410b0b927ed66be50a09574b7982 added GF_CLIENT_PID_GLFS_HEALD as the pid for all fops made by glfsheal. If we leverage this and allow lookups in afr when pid is GF_CLIENT_PID_GLFS_HEALD, split-brain resolution commands will work for replica 3 volumes too. Likewise, the check is added in shard_lookup as well to permit resolving split-brains by specifying "/.shard/shard-file.xx" as the file name (which previously used to fail with EPERM).

* xlators: fixes logically dead code.yatipadia2019-10-031-5/+0
| | | | | | | | | | | | | | | This patch addresses CID-1124388. Problem: When we reach the "out" section in ra_priv_dump(), if the condition (ret && conf) holds true, then the value of "add_section" will always be true. So the condition (add_section == _gf_false) will be a dead code. Fix:"add_section" has no use in the whole block and was making part of the block as logically dead code and hence, removed it.

* protocol/handshake: pass volume-id for extra checkAmar Tumballi2019-09-305-1/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With added check of volume-id during handshake, we can be sure to not connect with a brick if this gets re-used in another volume. This prevents any accidental issues which can happen with a stale client process lurking along. Also added test case for testing same volume name which would fetch a different volfile (ie, different bricks, different type), and a different volume name, but same brick. For reference: Currently a client<->server handshake happens in glusterfs through protocol/client translator (setvolume) to protocol/server using a dictionary which containes many keys. Rejection happens in server side if some of the required keys are missing in handshake dictionary. Till now, there was no single unique identifier to validate for a client to tell server if it is actually talking to a corresponding server. All we look in protocol/client is a key called 'remote-subvolume', which should match with a subvolume name in server volume file, and for any volume with same brick name (can be present in same cluster due to recreate), it would be same. This could cause major issue, when a client was connected to a given brick, in one volume would be connected to another volume's brick if its re-created/re-used. To prevent this behavior, we are now passing along 'volume-id' in handshake, which would be preserved for the life of client process, which can prevent this accidental connections. NOTE: This behavior wouldn't be applicable for user-snapshot enabled volumes, as snapshotted volume's would have different volume-id.

| | | | | | | | | | | | | | | When self-heal daemon receives an inodelk contention notification, it tries to locate the related inode using inode_find() and the inode table owned by top-most xlator, which in this case doesn't have any inode table. This causes many messages to be logged by inode_find() function because the inode table passed is NULL. This patch prevents this by making sure the inode table is not NULL before calling inode_find().

* read-ahead/io-cache: turn off by defaultRaghavendra Gowdappa2019-09-261-2/+2
| | | | | | | | | | | | | | | | We've found perf xlators io-cache and read-ahead not adding any performance improvement. At best read-ahead is redundant due to kernel read-ahead and at worst io-cache is degrading the performance for workloads that doesn't involve re-read. Given that VFS already have both these functionalities, this patch makes these two translators turned off by default for native fuse mounts. For non-native fuse mounts like gfapi (NFS-ganesha/samba) we can have these xlators on by having custom profiles.

| | | | | | | | | | | | | | | | | | | reconnect Bricks cleanup any granted locks after a client disconnects and currently these locks are not healed after a reconnect. This means post reconnect a competing process could be granted a lock even though the first process which was granted locks has not unlocked. By not re-opening fds, subsequent operations on such fds will fail forcing the application to close the current fd and reopen a new one. This way we prevent any silent corruption. A new option "client.strict-locks" is introduced to control this behaviour. This option is set to "off" by default.

* glusterd: stop stale bricks during handshaking in brick mux modeAtin Mukherjee2019-08-254-9/+55
| | | | | | | | | | | | | | | | | | | | This patch addresses two problems: 1. During friend handshaking, if a volume is imported due to change in the version, the old bricks were not stopped which would lead to a situation where bricks will run with old volfiles. 2. As part of attaching shd service in glusterd_attach_svc, there might be a case that the volume for which we're attempting to attach a shd service might become stale and in the process of deletion and hence in every retrials (if the rpc connection isn't ready) check for the existance of the volume and then only attempt the further attach request.

* glusterd: Add warning and abort in case of failures in migration during ↵heal-infoVishal Pandey2019-08-251-0/+11
| | | | | | | | | | | | | | | | | | remove-brick commit Problem - Currently remove-brick commit goes through even though there were files that failed to migrate or were skipped. There is no warning raised to the user. Solution- Add a check in the remove brick staging phase to verify if the status of the rebalnce process is complete but there has been failures or some skipped files while migration, In this case user will be given a warning and remove-brick commit. User will need to use the force option to remove the bricks. Fixes: bz#1514683 Signed-offby- Vishal Pandey <vpandey@redhat.com> Change-Id: I014d0f0afb4b2fac35ab0de52227f98dbae079d5

* ctime: Fix incorrect realtime passed to frame->root->ctimeKotresh HR2019-08-221-1/+1
| | | | | | | | | | | | On systems that don't support "timespec_get"(e.g., centos6), it was using "clock_gettime" with "CLOCK_MONOTONIC" to get unix epoch time which is incorrect. This patch introduces "timespec_now_realtime" which uses "clock_gettime" with "CLOCK_REALTIME" which fixes the issue.
