* gfapi: do not cache upcalls if the application is not interestedNiels de Vos2016-08-253-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the volume option 'features.cache-invalidation' is enabled, upcall events are sent from the brick process to the client. Even if the client is not interested in upcall events itself, md-cache or other xlators may benefit from them. By adding a new 'cache_upcalls' boolean in the 'struct glfs', we can enable the caching of upcalls when the application called glfs_h_poll_upcall(). NFS-Ganesha sets up a thread for handling upcalls in the initialization phase, and calls glfs_h_poll_upcall() before any NFS-client accesses the NFS-export. In the future there will be a more flexible registration API for enabling certain kind of upcall events. Until that is available, this should work just fine. Verificatio of this change is not trivial within our current regression test framework. The bug report contains a description on how to reliably reproduce the problem with the glusterfs-coreutils.

* gfapi: use const qualifier for glfs_*timens()Oleksandr Natalenko2016-08-102-6/+8
| | | | | | | | | | | | | | | | | | | | glfs_*timens() functions have the last argument of struct timespec type that is supposed to be const. Now using glfs_*timens() in fops, implemented on top of FUSE library, leads to compiler-time warning about discarding const qualifier. Introducing const qualifier does not break ABI, so let's just fix it.

Lets say @TIME T1: fs->active_subvol = A fs->next_subvol = B __glfs_active_subvol() //under lock fs->mutex { .... new_subvol = fs->next_subvol //which is B .... //Start migration from A to B __glfs_first_lookup(){ .... unlock fs->mutex //@TIME T2 network fop lock fs->mutex .... } .... //migration continue on B fs->active_subvol = fs->next_subvol //which is C (explained below) .... } @Time T2, lets say in another thread, graph_setup() is called with C, note that at T2, fs->mutex is unlocked. graph_stup(C...) { lock fs->mutex .... if (fs->next_subvol) // which is B destroy subvol (fs->next_subvol) .... fs->next_subvol = C .... unlock fs->mutex } Thus at the end of this, fs->old_subvol = A; fs->active_subvol = C; fs->next_subvol = NULL; which is wrong, as B completed migration, but was destroyed by graph_setup, and C never was migrated. Solution: ========= Any new graph can be in one of the 2 states: - Picked for migration, migration in progress (fs->mip_subvol) - Not picked so far for migration (fs->next_subvol) graph_setup() updates fs->next_subvol only, __glfs_active_subvol() moves fs->next_subvol to fs->mip_subvol and fs->next_subvol = NULL atomically, and then once the migration is complete, make that the fs->active_subvol Change-Id: Ib6ff0565105c5eedb912a43da4017cd413243612 BUG: 1343038 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/14722 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra Talur <rtalur@redhat.com> Reviewed-by: Rajesh Joseph <rjoseph@redhat.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

* gfapi: Fix IO error caused when there is consecutive graph switchesPoornima G2016-06-161-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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 Change-Id: Idf665cae0a8e27697fbfc5ec8d93a6d6bae3a4f1 BUG: 1332156 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/14148 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: Pranith Kumar Karampuri <pkarampu@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | 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.

Solution: Every time we receive a RPC_CLNT_DISCONNECT event in mgmt_rpc_notify, we need to check the transport type of the volfile server in the list and set the keys "transport.socket.connect-path" or "remote-host" accordingly.

* 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().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 .

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.

* gfapi: xattr key length check to avoid brick crashMilind Changire2015-10-092-0/+70
| | | | | | | | | | | | | | | | | | | Added check to test if xattr key length > max allowed for OS distribution and return: EINVAL if xattr name pointer is NULL or 0 length ENAMETOOLONG if xattr name length > max allowed for distribution Typically the VFS does this in the kernel for us. But since we are bypassing the VFS by providing the libgfapi to talk directly to the brick process, we need to add such checks.

* gfapi: transport and port are optional for glfs_set_volfile_serverRaghavendra Talur2015-09-281-12/+43
| | | | | | | | | | | | | | | | | | Only server is the required argument for glfs_set_volfile_server and both transport and port are optional. When glfs_set_volfile_server is invocated multiple times, only on the first invocation we replace port 0 with 24007 and transport NULL with "tcp". Hence, replacing the parameters at the entry function is the right way.
