* features/locks: error-out {inode,entry}lk fops with all-zero lk-ownerPranith Kumar K2019-04-165-15/+53
| | | | | | | | | | | | | | | | | 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. Fix: Disallow locks with lk-owner zero. fixes bz#1624701 Change-Id: I1c816280cffd150ebb392e3dcd4d21007cdd767f Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>
* libgfchangelog : use find_library to locate shared librarySunny Kumar2019-04-151-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: libgfchangelog.so: cannot open shared object file Due to hardcoded shared library name runtime loader looks for particular version of a shared library.

* core: Brick is not able to detach successfully in brick_mux environmentMohit Agrawal2019-04-141-0/+1
| | | | | | | | | | | | | | | | | | | | | Problem: In brick_mux environment, while volumes are stopped in a loop bricks are not detached successfully. Brick's are not detached because xprtrefcnt has not become 0 for detached brick. At the time of initiating brick detach process server_notify saves xprtrefcnt on detach brick and once counter has become 0 then server_rpc_notify spawn a server_graph_janitor_threads for cleanup brick resources.xprtrefcnt has not become 0 because socket framework is not working due to assigning 0 as a fd for socket. In commit dc25d2c1eeace91669052e3cecc083896e7329b2 there was a change in changelog fini to close htime_fd if htime_fd is not negative, by default htime_fd is 0 so it close 0 also.

* rpc/transport: Missing a ref on dict while creating transport objectMohammed Rafi KC2019-03-202-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | while creating rpc_tranpsort object, we store a dictionary without taking a ref on dict but it does an unref during the cleaning of the transport object. So the rpc layer expect the caller to take a ref on the dictionary before passing dict to rpc layer. This leads to a lot of confusion across the code base and leads to ref leaks. Semantically, this is not correct. It is the rpc layer responsibility to take a ref when storing it, and free during the cleanup. I'm listing down the total issues or leaks across the code base because of this confusion. These issues are currently present in the upstream master. 1) changelog_rpc_client_init 2) quota_enforcer_init 3) rpcsvc_create_listeners : when there are two transport, like tcp,rdma. 4) quotad_aggregator_init 5) glusterd: init 6) nfs3_init_state 7) server: init 8) client:init This patch does the cleanup according to the semantics.

* rpm: add thin-arbiter packageAmar Tumballi2019-03-111-2/+0
| | | | | | | | | | | | | | | | | | | Discussion on thin arbiter volume - https://github.com/gluster/glusterfs/issues/352#issuecomment-350981148 Main idea of having this rpm package is to deploy thin-arbiter without glusterd and other commands on a node, and all we need on that tie-breaker node is to run a single glusterfs command. Also note that, no other glusterfs installation needs thin-arbiter.so. Make sure RPM contains sample vol file, which can work by default, and a script to configure that volfile, along with translator image.

* WORM-Xlator: Maybe integer overflow when computing new atimeDavid Spisla2019-03-072-8/+8
| | | | | | | | | | | | | | | | | | | | The structs worm_reten_state_t and read_only_priv_t from read-only.h are using uint64_t values to store periods of retention and autocommmit. This seems to be dangerous since in worm-helper.c the function worm_set_state computes in line 97: stbuf->ia_atime = time(NULL) + retention_state->ret_period; stbuf->ia_atime is using int64_t because of the settings of struct iattr. So if there is a very very high retention period stored, there is maybe an integer overflow. What can be the solution? Using int64_t instead if uint64_t may reduce the probability of the occurance.

* features/sdfs: disable by defaultAmar Tumballi2019-01-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the feature enabled, some of the performance testing results, specially those which create millions of small files, got approximately 4x regression compared to version before enabling this. On master without this patch: 765 creates/sec On master with this patch : 3380 creates/sec Also there seems to be regression caused by this in 'ls -l' workload. On master without this patch: 3030 files/sec On master with this patch : 16610 files/sec This is a feature added to handle multiple clients parallely operating (specially those which race for file creates with same name) on a single namespace/directory. Considering that is < 3% of Gluster's usecase right now, it makes sense to disable the feature by default, so we don't penalize the default users who doesn't bother about this usecase. Also note that the client side translators, specially, distribute, replicate and disperse already handle the issue upto 99.5% of the cases without SDFS, so it makes sense to keep the feature disabled by default.

* Multiple files: reduce work while under lock.Yaniv Kaul2019-01-294-18/+22
| | | | | | | | | | | | | | | | | Mostly, unlock before logging. In some cases, moved different code that was not needed to be under lock (for example, taking time, or malloc'ing) to be executed before taking the lock. Note: logging might be slightly less accurate in order, since it may not be done now under the lock, so order of logs is racy. I think it's a reasonable compromise.

* features/shard: Ref shard inode while adding to fsync listKrutika Dhananjay2019-01-241-8/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: Lot of the earlier changes in the management of shards in lru, fsync lists assumed that if a given shard exists in fsync list, it must be part of lru list as well. This was found to be not true. Consider this - a file is FALLOCATE'd to a size which would make the number of participant shards to be greater than the lru list size. In this case, some of the resolved shards that are to participate in this fop will be evicted from lru list to give way to the rest of the shards. And once FALLOCATE completes, these shards are added to fsync list but without a ref. After the fop completes, these shard inodes are unref'd and destroyed while their inode ctxs are still part of fsync list. Now when an FSYNC is called on the base file and the fsync-list traversed, the client crashes due to illegal memory access. FIX: Hold a ref on the shard inode when adding to fsync list as well. And unref under following conditions: 1. when the shard is evicted from lru list 2. when the base file is fsync'd 3. when the shards are deleted.

| | | | | | | | | | | | | | | | | This patch helps enable IPv6 connections in the cluster. The default address-family is IPv4 without using this option explicitly. When address-family is set to "inet6" in the /etc/glusterfs/glusterd.vol file, the mount command-line also needs to have -o xlator-option="transport.address-family=inet6" added to it. This option also gets added to the brick command-line. Snapshot and gfapi use-cases should also use this option to pass in the inet6 address-family.

* features/shard: Fix launch of multiple synctasks for background deletionKrutika Dhananjay2019-01-112-71/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: When multiple sharded files are deleted in quick succession, multiple issues were observed: 1. misleading logs corresponding to a sharded file where while one log message said the shards corresponding to the file were deleted successfully, this was followed by multiple logs suggesting the very same operation failed. This was because of multiple synctasks attempting to clean up shards of the same file and only one of them succeeding (the one that gets ENTRYLK successfully), and the rest of them logging failure. 2. multiple synctasks to do background deletion would be launched, one for each deleted file but all of them could readdir entries from .remove_me at the same time could potentially contend for ENTRYLK on .shard for each of the entry names. This is undesirable and wasteful. FIX: Background deletion will now follow a state machine. In the event that there are multiple attempts to launch synctask for background deletion, one for each file deleted, only the first task is launched. And if while this task is doing the cleanup, more attempts are made to delete other files, the state of the synctask is adjusted so that it restarts the crawl even after reaching end-of-directory to pick up any files it may have missed in the previous iteration. This patch also fixes uninitialized lk-owner during syncop_entrylk() which was leading to multiple background deletion synctasks entering the critical section at the same time and leading to illegal memory access of base inode in the second syntcask after it was destroyed post shard deletion by the first synctask.

On Ubuntu 16.04 the following warnings were reported by Amudhan: CC barrier.lo barrier.c: In function ‘notify’: barrier.c:499:33: warning: switch condition has boolean value [-Wswitch-bool] switch (past) { ^ barrier.c: In function ‘reconfigure’: barrier.c:565:25: warning: switch condition has boolean value [-Wswitch-bool] switch (past) { ^ Change-Id: Ifb6b75058dff8c789b729c76530a1358d391f4d1 Updates: bz#1193929 Reported-by: Amudhan P <amudhan83@gmail.com> Signed-off-by: Niels de Vos <ndevos@redhat.com>

* posix: use synctask for janitorPoornima G2018-12-191-3/+3
| | | | | | | | | | | | | | With brick mux, the number of threads increases as the number of bricks increases. As an initiative to reduce the number of threads in brick mux scenario, replacing janitor thread to use synctask infra. Now close() and closedir() handle by separate janitor thread which is linked with glusterfs_ctx.

* locks: handle "clear locks" xattr in fgetxattr tooCsaba Henk2018-12-143-50/+82
| | | | | | | | | | | | | | The lock clearing procedure was kicked in only in getxattr context. We need it to work the same way if it's triggered via fgetxattr (as is the case with interrupt handling). Also cleaned up the instrumentation a bit (more logs, proper management of allocated data). updates: #465 Change-Id: Icfca26ee181da3b8e15ca3fcf61cd5702e2730c8 Signed-off-by: Csaba Henk <csaba@redhat.com>
* Multiple posix related files: several modificationsYaniv Kaul2018-12-146-232/+169
| | | | | | | | | | | | | | | | | | | | | | | | Just looked at posix.c and related code and performed some changes and cleanups. The only important one is #3 below, but surely the others (#2 and #4) need careful review. Changes to other files are as they were related to code paths in posix.c. I'll send a separate patch for other posix related files. Main changes: 1. Proper initializtion for parameters, where it made sense. 2. Logged outside the lock in several places. 3. Moved from CALLOC to MALLOC where it made sense. 4. Aligned structures. 5. moved dictionary functions to use _sizen where possible. (dict_get() -> dict_get_sizen() for example) Compile-tested only!

* clang: Fix various missing checks for empty listShyamsundarR2018-12-145-92/+132
| | | | | | | | | | | | | | | | | | | | When using list_for_each_entry(_safe) functions, care needs to be taken that the list passed in are not empty, as these functions are not empty list safe. clag scan reported various points where this this pattern could be caught, and this patch fixes the same. Additionally the following changes are present in this patch, - Added an explicit op_ret setting in error case in the macro MAKE_INODE_HANDLE to address another clang issue reported - Minor refactoring of some functions in quota code, to address possible allocation failures in certain functions (which in turn cause possible empty lists to be passed around) Change-Id: I1e761a8d218708f714effb56fa643df2a3ea2cc7 Updates: bz#1622665 Signed-off-by: ShyamsundarR <srangana@redhat.com>

* copy_file_range support in GlusterFSRaghavendra Bhat2018-12-124-2/+29

It is expected to come in the upcoming release of linux-4.20 So, as of now, executing copy_file_range fop on a fused based filesystem results in fuse kernel module sending read on the source fd and write on the destination fd. Therefore a small gfapi based tool has been written to be able test the copy_file_range fop. This tool is similar (in functionality) to the example program given in copy_file_range man page. So, running regular copy_file_range on a fuse mount point and running gfapi based glfs-copy-file-range tool gives some idea about how fast, the copy_file_range (or reflink) can be. On the local machine this was the result obtained. mount -t glusterfs workstation:new /mnt/glusterfs [root@workstation ~]# cd /mnt/glusterfs/ [root@workstation glusterfs]# ls file [root@workstation glusterfs]# cd [root@workstation ~]# time /tmp/a.out /mnt/glusterfs/file /mnt/glusterfs/new real 0m6.495s user 0m0.000s sys 0m1.439s [root@workstation ~]# time glfs-copy-file-range $(hostname) new /tmp/glfs.log /file /rrr OPEN_SRC: opening /file is success OPEN_DST: opening /rrr is success FSTAT_SRC: fstat on /rrr is success copy_file_range successful real 0m0.309s user 0m0.039s sys 0m0.017s This tool needs following arguments 1) hostname 2) volume name 3) log file path 4) source file path (relative to the gluster volume root) 5) destination file path (relative to the gluster volume root) "glfs-copy-file-range <hostname> <volume> <log file path> <source> <destination>" - Added a testcase as well to run glfs-copy-file-range tool * io-stats changes to capture the fop for profiling * NOTE: - Added conditional check to see whether the copy_file_range syscall is available or not. If not, then return ENOSYS. - Added conditional check for kernel minor version in fuse_kernel.h and fuse-bridge while referring to copy_file_range. And the kernel minor version is kept as it is. i.e. 24. Increment it in future when there is a kernel release which contains the support for copy_file_range fop in fuse kernel module. * The document which contains a writeup on this enhancement can be found at https://docs.google.com/document/d/1BSILbXr_knynNwxSyyu503JoTz5QFM_4suNIh2WwrSc/edit Change-Id: I280069c814dd21ce6ec3be00a884fc24ab692367 updates: #536 Signed-off-by: Raghavendra Bhat <raghavendra@redhat.com>
