* protocol/client: unchecked return valueShwetha Acharya2018-11-201-1/+6
| | | | | | | | | | | | | | Problem: In client_process_response_v2, value returned from function client_post_common_dict is not checked for errors before being used.

* snapview-server: close the gfapi handle present in a forgotten inodeRaghavendra Bhat2018-11-201-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the snapdaemon can reach the lru limit of the inode table and start sending forgets on the inodes that are least recently used. snapview-server maintains the mapping between the domain of the snapdaemon and the gfapi instance which it uses to access the snapshots via a handle that is stored in the inode context of snapdaemon's inode. The handle is glfs_h_object structure which itself points to the actual inode present in the gfapi world. But, when snapview-server receives forget on a inode, it deleted the inode context without actually closing the handle it had obtained to map the inode from snapdaemon to the inode in gfapi world. So, this change makes sure that, the handle is closed as part of the inode forget. And this closure of the handle will result in gfapi world receiving forget and unref on its corresponding inode. But care must be taken to ensure before the closure to ensure that the gfapi instance from which the handle came from, is still valid and not destroyed. Otherwise, sending a forget downward to the gfapi world might result in the access of freed pointers. Hence, the snapview-server xlator first checks whether that gfapi instance is still there or not and then proceeds with closure of the handle.

* cluster/dht: sync brick root perms on add brickN Balachandran2018-11-192-22/+14
| | | | | | | | | | | | | | | | | If a single brick is added to the volume and the newly added brick is the first to respond to a dht_revalidate call, its stbuf will not be merged into local->stbuf as the brick does not yet have a layout. The is_permission_different check therefore fails to detect that an attr heal is required as it only considers the stbuf values from existing bricks. To fix this, merge all stbuf values into local->stbuf and use local->prebuf to store the correct directory attributes.

* lease: Treat unlk request as noop if lease not foundSoumya Koduri2018-11-172-4/+16
| | | | | | | | | | | | | | | | When the glusterfs server recalls the lease, it expects client to flush data and unlock the lease. If not it sets a timer (starting from the time it sends RECALL request) and post timeout, it revokes it. Here we could have a race where in client did send UNLK lease request but because of network delay it may have reached after server revokes it. To handle such situations, treat such requests as noop and return sucesss. Change-Id: I166402d10273f4f115ff04030ecbc14676a01663 updates: bz#1648768 Signed-off-by: Soumya Koduri <skoduri@redhat.com>
* leases: Fix incorrect inode_ref/unrefsSoumya Koduri2018-11-172-3/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From testing & code-reading, found couple of places where we incorrectly unref the inode resulting in use_after_free crash or ref leaks. This patch addresses couple of them. a) When we try to grant the very first lease for a inode, inode_ref is taken in __add_lease. This ref should be active till all the leases granted to that inode are released (i.e, till lease_cnt > 0). In addition even after lease_cnt becomes '0', the inode should be active till all the blocked fops are resumed. Hence release this ref, after resuming all those fops. To avoid granting new leases while resuming those fops, defined a new boolean (blocked_fops_resuming) to flag it in the lease_ctx. b) 'new_lease_inode' which creates new lease_inode_entry and takes ref on inode, is used while adding that entry to client_list and recall_list. Use its counter function '__destroy_lease_inode' which does unref while removing those entries from those lists. c) inode ref is also taken when added to timer->data. Unref the same after processing timer->data. Change-Id: Ie77c78ff4a971e0d9a66178597fb34faf39205fb updates: bz#1648768 Signed-off-by: Soumya Koduri <skoduri@redhat.com>

* core: fix strncpy warningsKaleb S. KEITHLE2018-11-158-46/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since gcc-8.2.x (fedora-28 or so) gcc has been emitting warnings about buggy use of strncpy. Most uses that gcc warns about in our sources are exactly backwards; the 'limit' or len is the strlen/size of the _source param_, giving exactly zero protection against overruns. (Which was, after all, one of the points of using strncpy in the first place.) IOW, many warnings are about uses that look approximately like this: ... char dest[8]; char src[] = "this is a string longer than eight chars"; ... strncpy (dest, src, sizeof(src)); /* boom */ ... The len/limit should be sizeof(dest). Note: the above example has a definite over-run. In our source the overrun is typically only theoretical (but possibly exploitable.) Also strncpy doesn't null-terminate on truncation; snprintf does; prefer snprintf over strncpy. Mildly surprising that coverity doesn't warn/isn't warning about this.

* glusterfsd: Make each multiplexed brick sign inPrashanth Pai2018-11-123-5/+34
| | | | | | | | | | | | | | | | | | | | | | | NOTE: This change will be consumed by brick mux implementation of glusterd2 only. No corresponsing change in glusterd1 has been made. When a multiplexed brick process is shutting down, it sends sign out requests to glusterd for all bricks that it contains. However, sign in request is only sent for a single brick. Consequently, glusterd has to use some tricky means to repopulate pmap registry with information of multiplexed bricks during glusterd restart. This change makes each multiplexed brick send a sign in request to glusterd2 which ensures that glusterd2 can easily repopulate pmap registry with port information. As a bonus, sign in request will now also contain PID of the brick sending the request so that glusterd2 can rely on this instead of having to read/manage brick pidfiles.

| | | | | | | | | | | | | | | | | | | | | | | | | Otherwise, gnfs will crash if we try to get nfs clients status in following situation. Also see commit 2f9e555f. Reproducible Steps: 1. systemctl restart glusterd; gluster volume status rep 2. systemctl restart glusterd; gluster volume status rep nfs clients step 1 works ok, but step 2 will lead localhost gnfs crash with certain probability. /lib64/libglusterfs.so.0(+0x270f0)[0x7effb6c7b0f0] /lib64/libglusterfs.so.0(gf_print_trace+0x334)[0x7effb6c854a4] /lib64/libc.so.6(+0x35270)[0x7effb52e7270] /usr/sbin/glusterfs(glusterfs_handle_node_status+0x155)[0x7effb7196905] /lib64/libglusterfs.so.0(+0x63f40)[0x7effb6cb7f40] /lib64/libc.so.6(+0x46d40)[0x7effb52f8d40] Updates: bz#1646869 Change-Id: Ia4cb009f821d32b2d18ba48d3467cc81a4b07747 Signed-off-by: Xie Changlong <xiechanglong@cmss.chinamobile.com> Signed-off-by: Hu Jianfei <hujianfei@cmss.chinamobile.com>

* libglusterfs/src/iobuf.c: don't forget to unlock a mutexYaniv Kaul2018-11-061-0/+1
| | | | | | | | | | | | | | | | commit ed83a4ee7b73e6b04694d1ac11ed25d2983ac943 changed locking order and forgot to unlock in a negative path (when index was -1). Coverity caught it (thanks!) as CID 1396581: Program hangs (LOCK) Note: I'm unlocking before logging the failure. I think it's the right order - logging can take a while (especially if your disk is slow).
