* logging.c/h: aggressively remove sprintfs()Yaniv Kaul2019-04-252-328/+201
| | | | | | | | | | | | | | | | | | | | | | Try to reduce the number of sprintf() and string copies until we finally log a log line. Specifically, do not sprintf separately the timestr string and do not sprintf/strcpy the appmsgstr separately - just stick it with the header. Hoping I did not leak anything or changed the log line formatting. Also, allocate 4K (GF_LOG_BACKTRACE_SIZE) of memory dynamically for trace output - only if trace was actually requested (previously, it was unconditionally) In addition, some minor code formatting (unrelated to the above). updates: bz#1193929 Signed-off-by: Yaniv Kaul <ykaul@redhat.com> Change-Id: Id2ccc85f9213a2b1c6eaa4a2f58ce043eac1824f

* core: avoid dynamic TLS allocation when possibleXavi Hernandez2019-04-2412-492/+114
| | | | | | | | | | | | | | | | | | | Some interdependencies between logging and memory management functions make it impossible to use the logging framework before initializing memory subsystem because they both depend on Thread Local Storage allocated through pthread_key_create() during initialization. This causes a crash when we try to log something very early in the initialization phase. To prevent this, several dynamically allocated TLS structures have been replaced by static TLS reserved at compile time using '__thread' keyword. This also reduces the number of error sources, making initialization simpler.

* cluster/ec: fix fd reopenXavi Hernandez2019-04-2316-285/+377
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently EC tries to reopen fd's that have been opened while a brick was down. This is done as part of regular write operations, just after having acquired the locks, and it's sent as a sub-fop of the main write fop. There were two problems: 1. The reopen was attempted on all UP bricks, even if a previous lock didn't succeed. This is incorrect because most probably the open will fail. 2. If reopen is sent and fails, the error is propagated to the main operation, causing it to fail when it shouldn't. To fix this, we only attempt reopens on bricks where the current fop owns a lock, and we prevent any error to be propagated to the main fop. To implement this behaviour an argument used to indicate the minimum number of required answers has overloaded to also include some flags. To make the change consistent, it has been necessary to rename the argument, which means that a lot of files have been changed. However there are no functional changes. This change has also uncovered a problem in discard code, which didn't correctely process requests of small sizes because no real discard fop was being processed, only a write of 0's on some region. In this case some fields of the fop remained uninitialized or with incorrect values. To fix this, a new function has been created to simulate success on a fop and it's used in the discard case. Thanks to Pranith for providing a test script that has also detected an issue in this patch. This patch includes a small modification of this script to force data to be written into bricks before stopping them.

* core: fix hang issue in __gf_freeSusant Palai2019-04-221-1/+0
| | | | | | | | | | | | | | | Currently GF_ASSERT is done under mem_accounting lock at some places. On a GF_ASSERT failure, gf_msg_callingfn is called which calls gf_malloc internally and it takes the same mem_accounting lock leading to deadlock. This is a temporary fix to avoid any hang issue in master. https://review.gluster.org/#/c/glusterfs/+/22589/ is being worked on in the mean while so that GF_ASSERT can be used under mem_accounting lock.

* features/sdfs: Assign unique lk-owner for entrylk fopPranith Kumar K2019-04-221-0/+6
| | | | | | | | | | | | | sdfs is supposed to serialize entry fops by doing entrylk, but all the locks are being done with all-zero lk-owner. In essence sdfs doesn't achieve its goal of mutual exclusion when conflicting operations are executed by same client because two locks on same entry with same all-zero-owner will get locks.

* core: handle memory accounting correctlyXavi Hernandez2019-04-224-114/+105
| | | | | | | | | | | | | | | | | | | | When a translator stops, memory accounting for that translator is not destroyed (because there could remain memory allocated that references it), but mutexes that coordinate updates of memory accounting were destroyed. This caused incorrect memory accounting and even crashes in debug mode. This patch also fixes some other things: * Reduce the number of atomic operations needed to manage memory accounting. * Correctly account memory when realloc() is used. * Merge two critical sections into one. * Cleaned the code a bit.

* features/bit-rot-stub: clean the mutex after cancelling the signer threadRaghavendra Bhat2019-04-172-7/+59
| | | | | | | | | | | | | | | | | | When bit-rot feature is disabled, the signer thread from the bit-rot-stub xlator (the thread which performs the setxattr of the signature on to the disk) is cancelled. But, if the cancelled signer thread had already held the mutex (&priv->lock) which it uses to monitor the queue of files to be signed, then the mutex is never released. This creates problems in future when the feature is enabled again. Both the new instance of the signer thread and the regular thread which enqueues the files to be signed will be blocked on this mutex. So, as part of cancelling the signer thread, unlock the mutex associated with it as well using pthread_cleanup_push and pthread_cleanup_pop.

| | | | | | | | | | | | | | | | | Problem: Sometimes we find that developers forget to assign lk-owner for an inodelk/entrylk/lk before writing code to wind these fops. locks xlator at the moment allows this operation. This leads to multiple threads in the same client being able to get locks on the inode because lk-owner is same and transport is same. So isolation with locks can't be achieved.

| | | | | | | | | | | | | | | | | | When a gluster node in trusted storage pool has failed due to hardware issues, volume delete operation fails saying "Not all peers are up" and peer detach for failed node fails saying "Brick(s) with peer <peer_ip> exists in cluster". The idea here is to use either replace-brick or remove-brick command to remove all the bricks hosted by failed node and then re-attempting the peer detach. This change adds this trick in peer detach error message. fixes: bz#1697866 Change-Id: I0c58887479d31db603ad8d6535ea9d547880ccc8 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>
* core: only log seek errors if SEEK_HOLE/SEEK_DATA is availableNiels de Vos2019-04-111-0/+4
| | | | | | | | | | | | | | | | | | | On RHEL-6 there is no support for SEEK_HOLE/SEEK_DATA and this causes the POSIX xlator to return errno=EINVAL. Because of this, the rpc-server xlator will log all 'failed' seek attempts. When applications call seek() often, the brick logs can grow very quickly and fill up the disks. Messages that get logged are like [server-rpc-fops.c:2091:server_seek_cbk] 0-vol01-server: 4947: SEEK-2 (53920aee-062c-4598-aa50-2b4d7821b204), client: worker.example.com-7808-2019/02/08-18:04:57:903430-vol01-client-0-0-0, error-xlator: vol01-posix [Invalid argument] The problem can be reproduced by running a Gluster Server on RHEL-6, with a client running on RHEL-7. The client should execute an application that calls lseek() with SEEK_HOLE/SEEK_DATA.

* client/fini: return fini after rpc cleanupMohammed Rafi KC2019-04-112-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | There is a race condition in rpc_transport later and client fini. Sequence of events to happen the race condition 1) When we want to destroy a graph, we send a parent down event first 2) Once parent down received on a client xlator, we will initiates a rpc disconnect 3) This will in turn generates a child down event. 4) When we process child down, we first do fini for Every xlator 5) On successful return of fini, we delete the graph Here after the step 5, there is a chance that the fini on client might not be finished. Because an rpc_tranpsort ref can race with the above sequence. So we have to wait till all rpc's are successfully freed before returning the fini from client Change-Id: I20145662d71fb837e448a4d3210d1fcb2855f2d4 fixes: bz#1659708 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>
* features/cloudsync : Added some new functionsAnuradha Talur2019-04-107-94/+597
| | | | | | | | | | | | | This patch contains the following changes: 1) Store ID info will now be stored in the inode ctx 2) Added new readv type where read is made directly from the remote store. This choice is made by volume set operation. 3) cs_forget() was missing. Added it.

* tests: correctly check open fd's when gfid is missingXavi Hernandez2019-04-101-0/+3
| | | | | | | | | | | | | | | | | The helper funcion get_fd_count() returns how many open fd's has a given gfid on a brick. It could happen that the brick doesn't have information about that inode because it has not been previously accessed. Before this patch, the function returned "" when the inode was not present. This caused basic/ec/ec-fix-openfd.t test to fail because it was expecting '0' as the result. This patch forces get_fd_count() to return '0' when the gfid is not present in the state dump.

* protocol: add an option to force using old-protocolAmar Tumballi2019-04-104-3/+55
| | | | | | | | | | | | | | As protocol implements every fop, and in general a large part of the codebase. Considering our regression is run mostly in 1 machine, there was no way of forcing the client to use old protocol (while new one is available). With this patch, a new 'testing' option is provided which forces client to use old protocol if found. This should help increase the code coverage by at least 10k lines overall. updates: bz#1693692 Change-Id: Ie45256f7dea250671b689c72b4b6f25037cef948 Signed-off-by: Amar Tumballi <amarts@redhat.com>
