* gfapi : check the value "iovec" in glfs_io_async_cbk only for readJiffin Tony Thottan2016-07-041-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The glfs_io_async_cbk() is called from the cbk of all the async ops such as write, read, fsync, ftruncate. In all other cases, expect for read the value for "iovec" is NULL. From the code, glfs_io_async_cbk checks the value in common routine which may end up in failures. Thanks Joe Julian for finding issue and suggesting the fix.

* gfapi/upcall: Ignore handle create failuresSoumya Koduri2016-06-171-24/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In "glfs_h_poll_cache_invalidation", we need to send upcall only if there is a corresponding inode entry in the gfapi inode table for that handle. That's because the application will have reference to the inode as long as it operates on any handle. That means the only case in which we cannot find inode is when the application has closed the handle (either as part of unlink or for any other purpose). But since it will have no more references and will not be interested in any upcall event for that handle, we can safely ignore such cases. Note: This will affect only that particular applicaiton process/local libgfapi client.

* gfapi: Fix IO error caused when there is consecutive graph switchesPoornima G2016-06-171-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/#/c/14656/ Issue: Consider a simple situation, where glfs_init() is done, i.e. initial graph is up. Now perform 2 volume sets that results in 2 client side graph changes. After this perform some IO, the IO fails with ENOTCON. The only way to recover this client is i guess another graph switch or restart. What actually is happening from code perspective: Initial graph lets say A, followed by 2 consecutive graph switches to B and C without any IO those two switches. - graph_setup (A) as a result of GF_EVENT_CHILD_UP, and fs->next_subvol = A - glfs_init() results in fs->active_subvol = A, fs->next_subvol = NULL - graph_setup (B) as a result of GF_EVENT_CHILD_UP, and fs->next_subvol = B - graph_setup (C) as a result of GF_EVENT_CHILD_UP, and fs->next_subvol = C. It also sees that the previous graph B was never set as fs->active_subvol, i.e. no IO or anything happened on B, so can safely send GF_EVENT_PARENT_DOWN (by calling glfs_subvol_done(B)). This parent down on B, results in child_down(B), which is fine. But child_down also triggers graph_setup(B). - graph_setup(B) as a result of GF_EVENT_CHILD_DOWN, and fs->next_subvol = B, and GF_EVENT_PARENT_DOWN on C as explained above. This again leads to GF_EVENT_CHILD_DOWN on C. - graph_setup(C) as a result of GF_EVENT_CHILD_DOWN, and fs->next_subvol = C, and GF_EVENT_PARENT_DOWN on B as explained above. Thus both the graphs B and C are disconnected, and hence the ENOTCON Solution: Remove the call to graph_setup() when the event is GF_EVENT_CHILD_DOWN. It don't see any reason why graph_setup should be called when there is child_down. Not sure what the original reason was, to have graph_setup in child_down. git hostory shows the first patch itself had this call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | While investigating gfapi memory consumption with valgrind, valgrind reported several memory access issues. Also see the timer 'registry' being recreated (shortly) after being freed during teardown due to the way it's currently written. Passing ctx as data to gf_timer_proc() is prone to memory access issues if ctx is freed before gf_timer_proc() terminates. (And in fact this does happen, at least in valgrind.) gf_timer_proc() doesn't need ctx for anything, it only needs ctx->timer, so just pass that. Nothing ever calls gf_timer_registry_init(). Nothing outside of timer.c that is.

* gfapi: Fix a deadlock caused by graph switch while aio in progressPoornima G2016-05-061-206/+362
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCA: Currently async nature is achieved by submitting a syncop operation to synctask threads. Consider a scenario where the graph switch is triggered, the next write fop checks for the next available graph and sets fs->migration_in_progess and triggers the migration of fds and other things, which can cause some syncop_lookup operation. While this fop (on synctask thread) is waiting for syncop_lookup to return, lets say there are another 17 write async calls submitted, all these writes are blocked waiting for fs->migration_in_progress to be unset, hence all the 16 synctask threads are blocked waiting for fs->migration_in_progress to be unset. Now the syncop_lookup returns, but there are no synctask threads to process the lookup_cbk. If this syncop_lookup doesn't return, then fs->migration_in_progress can not be unset by the first fop. Thus causing a deadlock. To fix this deadlock, changing all the async APIs to use STACK_WIND, instead of syntask to achieve async nature. glfs_preadv_async is already implemented using STACK_WIND, now changing all the other async APIs also to do the same. This patch as such will not reduce the performance of async IO, the only thing that can affect is that, in case of write, the buf passed by application is copied onto iobuf in the same thread wheras before it was being copied in synctask thread. Since, the syncop + graph switch logic (lock across fops) is not a good candidate for synctask, changing the async APIs to use STACK_WIND Backport of http://review.gluster.org/#/c/14148/ Change-Id: Idf665cae0a8e27697fbfc5ec8d93a6d6bae3a4f1 BUG: 1333266 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/14221 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra Talur <rtalur@redhat.com> Reviewed-by: Rajesh Joseph <rjoseph@redhat.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

* gfapi: Use inode_forget in case of handle objectsSoumya Koduri2016-02-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently with gfapi, even if applications release their reference on paritular inode entries, those entries never get destroyed as they shall always have positive nlookup count unless inode_table exceeds lru limit. Since inodes and their contexts can consume considerable amount of memory, applications may end up consuming lot of memory and may even get OOM killed. To avoid that, have considered below approaches (for handle based access)- a) Do 'inode_lookup' only if the corresponding inode is created for the first time and forget it during close of the handle This shall not work as multiple handle objects can refer to same inode entry and inode_forget from second handle object onwards shall result in assert. b) Do 'inode_lookup' during a handle or fd creation But this approach shall affect the performance of the fops which operate on neither handle nor fd. c) current approach taken- Applications using glfs handle objects hold a reference on corresponding inode entries. Hence it is safe to forget those inodes and make nlookup count to '0' while trying to delete those handle objects. That way the last unref (i.e, from the last handle close) shall result in inode_destroy().

* glusterd: Bug fixes for IPv6 supportNithin D2016-02-201-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Glusterd not working using ipv6 transport. The idea is with proper glusterd.vol configuration, 1. glusterd needs to listen on default port (240007) as IPv6 TCP listner. 2. Volume creation/deletion/mounting/add-bricks/delete-bricks/peer-probe needs to work using ipv6 addresses. 3. Bricks needs to listen on ipv6 addresses. All the above functionality is needed to say that glusterd supports ipv6 transport and this is broken. Fix: When "option transport.address-family inet6" option is present in glusterd.vol file, it is made sure that glusterd creates listeners using ipv6 sockets only and also the same information is saved inside brick volume files used by glusterfsd brick process when they are starting. Tests Run: Regression tests using ./run-tests.sh IPv4: Ran manually till tests/basic/rpm.t . IPv6: (Need to add the above mentioned config and also add an entry for "hostname ::1" in /etc/hosts) Started failing at ./tests/basic/glusterd/arbiter-volume-probe.t and ran successfully till here Unit Tests using Ipv6 peer probe add-bricks remove-bricks create volume replace-bricks start volume stop volume delete volume Change-Id: Iebc96e6cce748b5924ce5da17b0114600ec70a6e BUG: 1117886 Signed-off-by: Nithin D <nithind1988@yahoo.in> Reviewed-on: http://review.gluster.org/11988 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | There is chance that before the async fop is complete client can send a close. libgfapi destroys glfd on close. Therefore it can lead to crash or unexpected behaviour when the pening fop reaches libgfapi layer. Currently we don't provide any api to cancel these outstanding fops neither we check if the glfd is already closed or not. Therefore as a fix provided refcount for glfd. Each fop (sync or async) will take a ref and once the fop is complete it will unref the refcount. We should not call the registered callback function if glfd is already closed. To achieve this we maintain state of glfd so that we can safely take a call if the fd is closed or not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've been lucky that we haven't had any symbol collisions until now. Now we have a collision between the snapview-client's svc_lookup() and libntirpc's svc_lookup() with nfs-ganesha's FSAL_GLUSTER and libgfapi. As a short term solution all the snapview-client's FOP methods were changed to static scope. See http://review.gluster.org/11805. This works in snapview-client because all the FOP methods are defined in a single source file. This solution doesn't work for other xlators with FOP methods defined in multiple source files. To address this we link with libtool's '-export-symbols $symbol-file' (a wrapper around `ld --version-script ...` --- on linux anyway) and only export the minimum required symbols from the xlator sharedlib. N.B. the libtool man page says that the symbol file should be named foo.sym, thus the rename of *.exports to *.sym. While foo.exports worked, we will follow the documentation. Signed-off-by: Kaleb S.

* rpc: add owner xlator argument to rpc_clnt_newKrishnan Parthasarathi2015-08-122-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The @owner argument tells RPC layer the xlator that owns the connection and to which xlator THIS needs be set during network notifications like CONNECT and DISCONNECT. Code paths that originate from the head of a (volume) graph and use STACK_WIND ensure that the RPC local endpoint has the right xlator saved in the frame of the call (callback pair). This guarantees that the callback is executed in the right xlator context. The client handshake process which includes fetching of brick ports from glusterd, setting lk-version on the brick for the session, don't have the correct xlator set in their frames. The problem lies with RPC notifications. It doesn't have the provision to set THIS with the xlator that is registered with the corresponding RPC programs. e.g, RPC_CLNT_CONNECT event received by protocol/client doesn't have THIS set to its xlator. This implies, call(-callbacks) originating from this thread don't have the right xlator set too. The fix would be to save the xlator registered with the RPC connection during rpc_clnt_new. e.g, protocol/client's xlator would be saved with the RPC connection that it 'owns'. RPC notifications such as CONNECT, DISCONNECT, etc inherit THIS from the RPC connection's xlator.

* libgfapi: Gracefully exit when glfd is invalidPrashanth Pai2015-07-072-4/+6
| | | | | | | | | | | | | | | When glfs_* methods operating on glfd are invoked after calling glfs_close(), the program segfaults inside __GLFS_ENTRY_VALIDATE_FD trying to deference glfd->fd->inode which is invalid. Also, returning EBADF seemed more specific than EINVAL.

* libgfapi: send explicit lookups on inodes linked in readdirpRaghavendra Bhat2015-07-022-14/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | If the inode is linked via readdirp, then the consuners of gfapi which are using handles (got either in lookup or readdirp) might not send an explicit lookup on that object again (ex: NFS, samba, USS). If there is a replicate volume where the replicas of the object are not in sync, then readdirp followed by fops might lead data being served from the subvolume which is not in sync with latest data. And since lookup is needed to trigger self-heal on that object the consumers might keep getting wrong data until an explicit lookup is not done. Fuse handles this situation by sending an explicit lookup by itself (fuse xlator) on those inodes which are linked via readdirp, whenever a fop comes on that inode. The same procedure is done in gfapi as well to address this situation.
