* xlators: protocol: Fix deferencing pointer after free coverity issuesBhumika Goyal2018-08-213-32/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | The pointer of type struct iobuf * is getting dereferenced after getting freed by iobuf_unref function. Therefore, move this function after all the dereferences of this pointer type. Also, it is useful coding standard to have iobuf_unref just after iobref_add. So, move iobref_add too. Occurences found using Coccinelle script: @@ identifier rsphdr_iobuf; expression E; identifier func; @@ *iobuf_unref(rsphdr_iobuf); ... *E = func(rsphdr_iobuf); Fixes CID: 1390517, 1390278, 1388666, 1356588, 1356587 at [1]. and also some more occurences which were found using the above script but not caught by Coverity.

* performance/readdir-ahead: keep stats of cached dentries in sync with ↵Krutika Dhananjay2018-08-185-26/+621
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | modifications PROBLEM: Stats of dentries that are readdirp'd ahead can become stale due to fops like writes, truncate etc that modify the file pointed by dentries. When a readdir is finally wound at offset corresponding to these entries, the iatts that are returned to the application come from readdir-ahead's cache, which are stale by now. This problem gets further aggravated when caching translators/modules cache and continue to serve this stale information. FIX: * Store the iatt in context of the inode pointed by dentry. * Whenever the inode pointed by dentry undergoes modification, in cbk of modification fop, update the iatt stored in inode-ctx to reflect the modification. * When serving a readdirp response from application, update iatts of dentries with the iatts stored in the context of inodes pointed by these dentries. * Some fops don't have valid iatts in their responses. For eg., write response whose data is still cached in write-behind will have zeroed out stat. In this case keep only ia_type and ia_gfid and reset rest of the iatt members to zero. - fuse-bridge in this case just sends "entry" information back to kernel and attr is not sent. - gfapi sets entry->inode to NULL and zeroes out the entire stat * There is one tiny race between the entry creation and a readdirp on its parent dir, which could cause the inode-ctx setting and inode ctx reading to happen on two different inode objects. To prevent this, when entry->inode doesn't eqaul to linked_inode, - fuse-bridge is made to send only "entry" information without attributes - gfapi sets entry->inode to NULL and zeroes out the entire stat.

* glusterd: ignore importing volume which is undergoing a delete operationAtin Mukherjee2018-08-165-6/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem explanation: Assuming in a 3 nodes cluster, if N1 originates a delete operation and while N1's commit phase completes, either glusterd service of N2 or N3 gets disconnected from N1 (before completing the commit phase), N1 will attempt to end up importing the volume which is in-flight for a delete in other nodes as a fresh resulting into an incorrect configuration state. Fix: Mark a volume as stage deleted once a volume delete operation passes it's staging phase and reset this flag during unlock phase. Now during this intermediate phase if the same volume gets imported to other peers, it shouldn't considered to be recreated. An automated .t is quite tough to implement with the current infra. Test Case: 1. Keep creating and deleting volumes in a loop on a 3 node cluster 2. Simulate n/w failure between the peers (ifdown followed by ifup) 3. Check if output of 'gluster v list | wc -l' is same across all 3 nodes during 1 & 2.

| | | | | | | | | | | | | | Setting the refresh flag in inode ctx in shard_rename_src_cbk() is applicable only when the dst file exists and is sharded and has a hard link > 1 at the time of rename. But this piece of code is exercised even when dst doesn't exist. In this case, the mount crashes because local->int_inodelk.loc.inode is NULL.

* cluster/dht: fix inode ref management in dht_heal_pathSusant Palai2018-08-141-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In dht_heal_path, the inodes are created & looked up from top to down. If the path is "a/b/c", then lookup will be done on a, then b and so on. Here is a rough snippet of the function "dht_heal_path". <snippet> if (bname) { ref_count - loc.inode = create/grep inode 1 - syncop_lookup (loc.inode) - linked_inode = inode_link (loc.inode) 2 /*clean up current loc*/ - loc_wipe(&loc) 1 /*set up parent and bname for next child */ - loc.parent = inode - bname = next_child_name } out: - inode_ref (linked_inode) 2 - loc_wipe (&loc) 1 </snippet> The problem with the above code is if _bname_ is empty ie the chain lookup is done, then for the next iteration we populate loc.parent anyway. Now that bname is empty, the loc_wipe is done in the _out_ section as well. Since, the loc.parent was set to the previous inode, we lose a ref unwantedly. Now a dht_local_wipe as part of the DHT_STACK_UNWIND takes away the last ref leading to inode_destroy. This problenm is observed currently with nfs-ganesha with the nameless lookup. Post the inode_purge, gfapi does not get the new inode to link and hence, it links the inode it sent in the lookup fop, which does not have any dht related context (layout) leading to "invalid argument error" in lookup path done parallely with tar operation. test done in the following way: - create two nfs client connected with two different nfs servers. - run untar on one client and run lookup continuously on the other. - Prior to this patch, invalid arguement was seen which is fixed with the current patch.
