* cluster/afr: GFID split-brain resolution with existing CLIkarthik-us2017-07-189-151/+584
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently there is no way for the admin from CLI to resolve gfid split-brain based on some policy like choice of the brick, mtime or size. Fix: With the existing CLI options based on size, mtime, and choice of brick, we do lookup on the parent for the specified file. As part of the lookup, if we find gfid mismatch, we resolve them based on the policy and return. If the file is not in gfid split- brain, then we check for the data and metadata split-brain in the getxattr code path, and resolve if any. This will work provided absolute path to the file with the CLI and not with gfid of the file. Hence the source-brick policy without any file path will also not resolve the gfid split-brain since it uses the gfid of the files. But it can resolve any other type of split-brains and skip the gfid mismatch resolution with the usual error message. Reverting the change https://review.gluster.org/17290. This patch resolves the issue.

* tests: disable IPC test-caseNiels de Vos2017-07-181-0/+3
| | | | | | | | | | | | | | | | | | | | | The IPC test-case is not correct, and can cause segfaults or hangs. The ipctest.py script calls glfs_ipc() with the `glfs_t` structure, but should do so with a `glfs_fd_t`. In addition, the test-case is written in a way that we do not suggest to use libgfapi. Python scripts are encouraged to use the bindings from the libgfapi-python project. It would be better to rewrite the test in C so that there is type-checking while compiling and no additional issues with portability (see `LD_PRELOAD` note in the `.t` file).

* program/GF-DUMP: Shield ping processing from traffic to GlusterfsRaghavendra G2017-07-184-6/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Program Since poller thread bears the brunt of execution till the request is handed over to io-threads, poller thread experiencies lock contention(s) in the control flow till io-threads, which slows it down. This delay invariably affects reading ping requests from network and responding to them, resulting in increased ping latencies, which sometimes results in a ping-timer-expiry on client leading to disconnect of transport. So, this patch aims to free up poller thread from executing code of Glusterfs Program. We do this by making * Glusterfs Program registering itself asking rpcsvc to execute its actors in its own threads. * GF-DUMP Program registering itself asking rpcsvc to _NOT_ execute its actors in its own threads. Otherwise program's ownthreads become bottleneck in processing ping traffic. This means that poller thread reads a ping packet, invokes its actor and hands the response msg to transport queue.

* cluster/rebalance: Fix hardlink migration failuresSusant Palai2017-07-132-15/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A brief about how hardlink migration works: - Different hardlinks (to the same file) may hash to different bricks, but their cached subvol will be same. Rebalance picks up the first hardlink, calculates it's hash(call it TARGET) and set the hashed subvolume as an xattr on the data file. - Now all the hardlinks those come after this will fetch that xattr and will create linkto files on TARGET (all linkto files for the hardlinks will be hardlink to each other on TARGET). - When number of hardlinks on source is equal to the number of hardlinks on TARGET, the data migration will happen. RACE:1 Since rebalance is multi-threaded, the first lookup (which decides where the TARGET subvol should be), can be called by two hardlink migration parallely and they may end up creating linkto files on two different TARGET subvols. Hence, hardlinks won't be migrated. Fix: Rely on the xattr response of lookup inside gf_defrag_handle_hardlink since it is executed under synclock. RACE:2 The linkto files on TARGET can be created by other clients also if they are doing lookup on the hardlinks. Consider a scenario where you have 100 hardlinks. When rebalance is migrating 99th hardlink, as a result of continuous lookups from other client, linkcount on TARGET is equal to source linkcount. Rebalance will migrate data on the 99th hardlink itself. On 100th hardlink migration, hardlink will have TARGET as cached subvolume. If it's hash is also the same, then a migration will be triggered from TARGET to TARGET leading to data loss. Fix: Make sure before the final data migration, source is not same as destination. RACE:3 Since a hardlink can be migrating to a non-hashed subvolume, a lookup from other client or even the rebalance it self, might delete the linkto file on TARGET leading to hardlinks never getting migrated. This will be addressed in a different patch in future.

* gfapi: prevent mem-pool leak in case glfs_new_fs() failsNiels de Vos2017-07-121-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | Commit 7039243e187 adds a call to mem_pools_init() so that the memory pool cleanup thread ("sweeper") is started. However, now it is possible that users of gfapi can not cleanup this thread because glfs_new() can return NULL, but the sweeper is still running. In case glfs_fs_new() fails, mem_pools_fini() needs to be called as well. This seems more correct than calling mem_pools_init() after glfs_fs_new(), and this makes using memory pools possible *really* early in the gfapi initialization.

* mgtm/core : use sha hash function for volfile checkMohammed Rafi KC2017-07-1011-44/+257
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are storing the entire volfile and using this to check volfile change. With brick multiplexing there will be lot of graphs per process which will increase the memory foot print of the process. So instead of storing the entire graph we could use sha256 and we can compare the hash to see whether volfile change happened or not. Also with Brick multiplexing, the direct comparison of vol file is not correct. There are two problems. Problem 1: We are currently storing one single graph (the last updated volfile) whereas, what we need is the entire graph with all atttached bricks. If we fix this issue, we have second problem Problem 2: With multiplexing we have a graph that contains multiple bricks. But what we are checking as part of the reconfigure is, comparing the entire graph with one single graph, which will always fail. Solution: We create list in glusterfs_ctx_t that stores sha256 hash of individual brick graphs. When a graph changes happens we compare the stored hash and the current hash. If the hash matches, then no need for reconfigure. Otherwise we first do the reconfigure and then update the hash. For now, gfapi has not changed this way. Meaning when gfapi volfile fetch or reconfigure happens, we still store the entire graph and compare, each memory. This is fine, because libgfapi will not load brick graphs. But changing the libgfapi will make the code similar in both glusterfsd-mgmt and api. Also it helps to reduce some memory.

Usage: `# gluster volume set all cluster.max-bricks-per-process <value>` If this option is not set then multiplexing will happen for now with no limitations set; i.e. a brick process will have as many bricks multiplexed to it as possible. In other words the current multiplexing behaviour won't change if this option isn't set to any value. This commit also introduces a brick process instance that contains information about brick processes, like the number of bricks handled by the process (which is 1 in non-multiplexing cases), list of bricks, and port number which also serves as an unique identifier for each brick process instance. The brick process list is maintained in 'glusterd_conf_t'.

| | | | | | | | | | | | | | | | | | | | | | | Solaris 10 uses WebNFS and not the MOUNT protocol. All permission checks for allowing/denying clients to mount are done through the MNT handlers. These handlers will not give out a filehandle to the NFS-client when mounting is denied. This prevents clients from successful mounting. However, over WebNFS a well known 'root-filehandle' is used directly with the NFSv3 protocol. When WebNFS was used, no permission checks (the "nfs.export-dir" option) were applied. Now the WebNFS mount-handler in Gluster/NFS calls the mnt3_parse_dir_exports() function that takes care of the permission checking.

| | | | | | | | | | | | | | | | | | | | | | | | | | When blocking locks are used, a new frame is allocated that is used to send the notification to the client once once the lock becomes available. In all other cases, the frame that contains the request from the client will be used for the reply. Because there was no way to track the different clients with their requests (captured in the call-state), the call-state could be free'd before the notification was sent to the client. This caused a use-after-free of the call-state and could trigger segfaults of the Gluster/NFS server or incorrect replies on (un)lock requests. By introducing a nlm4_notify_args structure, the call-state and frame can be tracked better. This prevents the possibility of segfaulting when the call-state is used after being free'd.

* groups: don't allocate auxiliary gid list on stackCsaba Henk2017-07-067-60/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When glusterfs wants to retrieve the list of auxiliary gids of a user, it typically allocates a sufficiently big gid_t array on stack and calls getgrouplist(3) with it. However, "sufficiently big" means to be of maximum supported gid list size, which in GlusterFS is GF_MAX_AUX_GROUPS = 64k. That means a 64k * sizeof(gid_t) = 256k allocation, which is big enough to overflow the stack in certain cases. A further observation is that stack allocation of the gid list brings no gain, as in all cases the content of the gid list eventually gets copied over to a heap allocated buffer. So we add a convenience wrapper of getgrouplist to libglusterfs called gf_getgrouplist which calls getgrouplist with a sufficiently big heap allocated buffer (it takes care of the allocation too). We are porting all the getgrouplist invocations to gf_getgrouplist and thus eliminate the huge stack allocation.

This is so that consumers of this feature do not have to be worried about monitoring when each 'ios-dump-interval' has passed and back up the resultant stats file well before the next interval has expired.

* nfs: make nfs3_call_state_t refcountedNiels de Vos2017-07-063-39/+42
| | | | | | | | | | | | | | | | | | | | | | | | There is no refcounting done of the nfs3_call_state_t structure, which seems to result in use-after-free problems in the NLM part of Gluster/NFS. The structure is initialized with two different functions, it is easier to have a single place to do this. The Gluster/NFS part will not use the refcounting, for now. This is being added to make the NLM code more stable. nfs3_call_state_wipe() will behave as before for Gluster/NFS, but cleanup is triggered through the refcounting now. This prevents major changes to the stable part of the NFS-server, and makes it possible to improve the NLM component separately.

* cli/xml: fix return handlingAtin Mukherjee2017-07-061-40/+52
| | | | | | | | | | | | | | | | | | | | The return code of xmlTextWriter* APIs says it returns either the bytes written (may be 0 because of buffering) or -1 in case of error. Now if the volume of the xml data payload is not huge then most of the time the data to be written gets buffered, however when this grows sometimes this APIs will return the total number of bytes written and then it becomes absolutely mandatory that every such call is followed by XML_RET_CHECK_AND_GOTO otherwise we may end up returning a non zero ret code which would result into the overall xml generation to fail.
