* protocol/client: Don't send fops till SETVOLUME is completev4.1.0rc0Raghavendra G2018-05-312-3/+9
| | | | | | | | | | | | | | | | | | An earlier commit set conf->connected just after rpc layer sends RPC_CLNT_CONNECT event. However, success of socket level connection connection doesn't indicate brick stack is ready to receive fops, as an handshake has to be done b/w client and server after RPC_CLNT_CONNECT event. Any fop sent to brick in the window between, * protocol/client receiving RPC_CLNT_CONNECT event * protocol/client receiving a successful setvolume response can end up accessing an uninitialized brick stack. So, set conf->connected only after a successful SETVOLUME.

* rpc: conditionally cleanup event slotMilind Changire2018-05-291-0/+8
| | | | | | | | | | | | | | | Problem: socket_server_event_handler() may call rpc_transport_unref() for a socket which may fail registration with the event sub-system.

* libgfapi: Fix lookup on rootKotresh HR2018-05-293-2/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | Lookup on root was sending "/" as the path. This will break the basename calculation in loc_copy and hence lookup on root was failing if the loc_copy was involved in the stack. With ctime, a first lookup on root initiates a metadata self heal because of ctime xattr not being same on all afr subvolumes. This results in loc_copy and hence the failure of lookup. Fix would be to send path with "." for the root.

* afr: fix bug-1363721.t failureRavishankar N2018-05-254-2/+63
| | | | | | | | | | | | | | | | | | | | | | | Problem: In the .t, when the only good brick was brought down, writes on the fd were still succeeding on the bad bricks. The inflight split-brain check was marking the write as failure but since the write succeeded on all the bad bricks, afr_txn_nothing_failed() was set to true and we were unwinding writev with success to DHT and then catching the failure in post-op in the background. Fix: Don't wind the FOP phase if the write_subvol (which is populated with readable subvols obtained in pre-op cbk) does not have at least 1 good brick which was up when the transaction started. Note: This fix is not related to brick muliplexing. I ran the .t 10 times with this fix and brick-mux enabled without any failures.

* rpc: Don't reset auth_value in disconnectKotresh HR2018-05-251-12/+48
| | | | | | | | | | | | | | | | | | | The auth_value was being reset to AUTH_GLUSTERFS_v2 during rpc disconnect. It shoud not be reset. The disconnect during portmap request can race with handshake.

* cluster/ec: Fix pre-op xattrop managementXavi Hernandez2018-05-253-32/+66
| | | | | | | | | | | | | | | | | | | | | | | Multiple pre-op xattrop can be simultaneously being processed. On the cbk it was checked if the fop was waiting for some specific data (like size and version) and, if so, it was assumed that this answer should contain that data. This is not true, since a fop can be waiting for some data, but it may come from the xattrop of another fop. This patch differentiates between needing some information and providing it. This is related to parallel writes. Disabling them fixed the problem, but also prevented concurrent reads. A change has been made so that disabling parallel writes still allows parallel reads.

* extras/hooks: Do not blindly remove volume share from smb.confAnoop C S2018-05-093-9/+12
| | | | | | | | | | | | | | | | | | When Gluster volumes are shared via Samba, any extra smb.conf parameter setting done by administrator to those shares are lost during restart of the volume. Instead of removing the whole share completely from smb.conf(via hook scripts during volume stop) it is better to make it temporarily unavailable to end-users till the volume is started again. Therefore we make use of a smb.conf parameter named 'available'[1] to achieve the above intend.

* posix/ctime: posix hooks to get consistent time xattrKotresh HR2018-05-0611-103/+233
| | | | | | | | | | | | This patch uses the ctime posix APIs to get consistent time across replica. The time attributes are got from from inode context or from on disk if not found and merged with iatt to be returned.

* posix: APIs in posix to get and set time attributesKotresh HR2018-05-0610-21/+683
| | | | | | | | | | | | | This is part of the effort to provide consistent time across distribute and replica set for time attributes (ctime, atime, mtime) of the object. This patch contains the APIs to set and get the attributes from on disk and in inode context.

* fuse: add support for kernel writeback cacheCsaba Henk2018-05-0410-4/+170
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Added kernel-writeback-cache command line and xlator option for requesting utilisation of the writeback cache of the kernel in FUSE_INIT (see [1]). - Added attr-times-granularity command line and xlator option via which granularity of the {a,m,c}time in stat (attr) data that we support can be indicated to kernel. This is a means to avoid divergence of the attr times between kernel and userspace that could occur with writeback-cache, while still maintaining maximum time precision the FUSE server is capable of (see [2]). - Handling FATTR_CTIME flag in FUSE_SETATTR that indicates presence of ctime in setattr payload. Currently we cannot associate arbitrary ctimes to files on backend, so we just touch them to update their ctimes to current time. Having ctimes in setattr payload is also a side effect of writeback cache (see [3] and [4]).

* gfapi : RECALL_LEASE implementationSoumya Koduri2018-05-0413-28/+556
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now there are two types of upcalls * poll method * registering callback But callback can be registered per fs and same callback fn shall be used for any lease recall with object handle as argument as done for cache invalidation. TODO: RECALL LEASE for each glfd (for future reference) (may be needed fo Samba as they do not deal with object handles. In case of RECALL_LEASE, we could associate separate cbk function for each glfd either by - extending pub_glfs_lease to accept new args (recall_cbk_fn, cookie) - or by defining new API "glfs_register_recall_cbk_fn (glfd, recall_cbk_fn, cookie) . In such cases, flag it and instead of calling below upcall functions, define a new one to go through the glfd list and invoke each of theirs recall_cbk_fn. Plus added following as well * passed lease id to dict in required arguments * added flag check in pub_glfs_open Updates: #350 Change-Id: I07a971f0f26ec6aae0b9f9a5613504317dee153b Signed-off-by: Soumya Koduri <skoduri@redhat.com> Signed-off-by: Poornima G <pgurusid@redhat.com> Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com>
* features/bitrot: print the path of the corrupted objectsRaghavendra Bhat2018-05-047-12/+292
| | | | | | | | | | | | | | | | | | | | | | | | | Currently "gluster volume bitrot <volume name> scrub status" gives the list of the corrupted objects (files as of now). But only the gfids of those corrupted objects are seen and one has to do getfattr, find etc operations to get the actual path of those objects for removal etc. This change makes an attempt to print the path of those files as much as possible. * Try to get the path using the on disk gfid2path xattr. * If the above operation fails, then go for in memory path (provided that the object has its dentry properly created and linked in the inode table of the brick where the corrupted object is present) So the gfid to path resolution is a soft resolution, i.e. based on the inode and dentry cache in the brick's memory. If the path cannot be obtained via inode table also, then only gfid is printed.
