* quota: fixes issue in quota.conf when setting large number of limitsSanoj Unnikrishnan2017-11-091-12/+33
| | | | | | | | | | | | | | | Problem: It was not possible to configure more than 7712 quota limits. This was because a stack buffer of size 131072 was used to read from quota.conf file. In the new format of quota.conf file each gfid entry takes 17bytes (16byte gfid + 1 byte type). So, the buf_size was not a multiple of gfid entry size and as per code this was considered as corruption. Solution: make buf size multiple of gfid entry size Change-Id: Id036225505a47a4f6fa515a572ee7b0c958f30ed BUG: 1510940 Signed-off-by: Sanoj Unnikrishnan <sunnikri@redhat.com>
* glusterd: display gluster volume status, when quorum type is serverSanju Rakonde2017-11-091-0/+6
| | | | | | | | | | | | | Problem: when server-quorum-type is server, after restarting glusterd in the node which is up, gluster volume status is giving incorrect information. Fix: check whether server is blank, before adding other keys into the dictionary. Change-Id: I926ebdffab330ccef844f23f6d6556e137914047 BUG: 1511339 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>
* mount/fuse: use fstat in getattr implementation if any opened fd is availableRaghavendra G2017-11-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The restriction of using fds opened by the same Pid means fds cannot be shared across threads of multithreaded application. Note that fops from kernel have different Pid for different threads. Imagine following sequence of operations: * Turn off performance.open-behind * Thread t1 opens an fd - fd1 - on file "file". Let's assume nodeid of "file" is "nodeid-file". * Thread t2 does RENAME ("newfile", "file"). Let's assume nodeid of "newfile" as "nodeid-newfile". * t2 proceeds to do fstat (fd1) The above set of operations can sometimes result in ESTALE/ENOENT errors. RENAME overwrites "file" with "newfile" changing its nodeid from "nodeid-file" to "nodeid-newfile" and post RENAME, "nodeid-file" is removed from the backend. If fstat carries nodeid-file as argument, which can happen if lookup has not refreshed the nodeid of "file" and since t2 doesn't have an fd opened, fuse_getattr_resume uses STAT which will fail as "nodeid-file" no longer exists. Since the above set of operations and sharing of fds across multiple threads are valid, this is a bug. The fix is to use any fd opened on the inode. In this specific example fuse_getattr_resume will find fd1 and winds down the call as fstat (fd1) which won't fail. Cross-checked with "Miklos Szeredi" <mszeredi.at.redhat.dot.com> for any security issues with this solution and he approves the solution. Thanks to "Miklos Szeredi" <mszeredi.at.redhat.dot.com> for all the pointers and discussions.

* nfs: Fix crash bug when mnt3_resolve_subdir_cbk() failsShreyas Siravara2017-11-011-0/+3
| | | | | | | | | | | | | | | Summary: When mnt3_resolve_subdir_cbk() fails (this can happen when racing operations), authorized_path is sometimes NULL. We try to run strlen() on this path and as a result we crash. This diff fixes that by checking if path is NULL before dereferencing it. Test Plan: Run with patch and observe that there is no crash. Prove test for auth code. BUG: 1365683 Change-Id: I2e2bdfdc61ae906788611e151d2c753b79b312df Signed-off-by: Shreyas Siravara <sshreyas@fb.com>

* glusterd: fix brick restart parallelismAtin Mukherjee2017-11-016-32/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | glusterd's brick restart logic is not always sequential as there is atleast three different ways how the bricks are restarted. 1. through friend-sm and glusterd_spawn_daemons () 2. through friend-sm and handling volume quorum action 3. through friend handshaking when there is a mimatch on quorum on friend import. In a brick multiplexing setup, glusterd ended up trying to spawn the same brick process couple of times as almost in fraction of milliseconds two threads hit glusterd_brick_start () because of which glusterd didn't have any choice of rejecting any one of them as for both the case brick start criteria met. As a solution, it'd be better to control this madness by two different flags, one is a boolean called start_triggered which indicates a brick start has been triggered and it continues to be true till a brick dies or killed, the second is a mutex lock to ensure for a particular brick we don't end up getting into glusterd_brick_start () more than once at same point of time.

| | | | | | | | | | | While stopping the brick which is to be reset and replaced delete_brick flag was passed as true which resulted glusterd to free up to source brick before the actual operation. This results commit force to fail failing to find the source brickinfo. Change-Id: I1aa7508eff7cc9c9b5d6f5163f3bb92736d6df44 BUG: 1507466 Signed-off-by: Atin Mukherjee <amukherj@redhat.com>
