* features/bitrot: compare the signature with proper lengthRaghavendra Bhat2018-12-121-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | * The scrubber was comparing the checksum of the file that it calculated (by reading the file) with the on disk signature (stored via xattr) wrongly. It was using strlen to calculate the signature, while the actual length of the signature is given by the brick. Just use the actual length that the brick provides instead of trying to calculate the signature length via strlen API. * In posix, gfid2path was using the same string that contains the list of all the xattrs of file to save the value of the gfid2path xattr as well. This causes confusion when gfid2path xattr is queried by scrubber for getting the actual path of a corrupted file. Use separate string to fetch the value of the xattr instead of the string that contains the list of xattrs.

* all: fix the format string exceptionsAmar Tumballi2018-11-091-3/+3
| | | | | | | | | | | | | | | | Currently, there are possibilities in few places, where a user-controlled (like filename, program parameter etc) string can be passed as 'fmt' for printf(), which can lead to segfault, if the user's string contains '%s', '%d' in it. While fixing it, makes sense to make the explicit check for such issues across the codebase, by making the format call properly.

* server: don't allow '/' in basenameAmar Tumballi2018-11-081-2/+2
| | | | | | | | | | | | | | | | Server stack needs to have all the sort of validation, assuming clients can be compromized. It is possible for a compromized client to send basenames with paths with '/', and with that create files without permission on server. By sanitizing the basename, and not allowing anything other than actual directory as the parent for any entry creation, we can mitigate the effects of clients not able to exploit the server.

* posix/ctime: Avoid log flood in posix_update_utime_in_mdataKotresh HR2018-11-081-4/+0
| | | | | | | | | | | | | | | | | | posix_update_utime_in_mdata() unconditionally logs an error if consistent time attributes features is not enabled. This log does not add any value, prints an incorrect errno & floods the log file. Hence nuking this log message in this patch.

* storage/posix: Do not fail entry creation fops if gfid handle already existsKrutika Dhananjay2018-10-222-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: > Change-Id: I84a5e54d214b6c47ed85671a880bb1c767a29f4d > Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com> > (cherry picked from commit 15c9976) > BUG: 1638453 PROBLEM: tests/bugs/shard/bug-1251824.t fails occasionally with EIO due to gfid mismatch across replicas on the same shard when dd is executed. CAUSE: Turns out this is due to a race between posix_mknod() and posix_lookup(). posix mknod does 3 operations, among other things: 1. creation of the entry itself under its parent directory 2. setting the gfid xattr on the file, and 3. creating the gfid link under .glusterfs. Consider a case where the thread doing posix_mknod() (initiated by shard) has executed steps 1 and 2 and is on its way to executing 3. And a parallel LOOKUP from another thread on noting that loc->inode->gfid is NULL, tries to perform gfid_heal where it attempts to create the gfid link under .glusterfs and succeeds. As a result, posix_gfid_set() through MKNOD (step 3) fails with EEXIST. In the older code, MKNOD under such conditions was NOT being treated as a failure. But commit e37ee6d changes this behavior by failing MKNOD, causing the entry creation to be undone in posix_mknod() (it's another matter that the stale gfid handle gets left behind if lookup has gone ahead and gfid-healed it). All of this happens on only one replica while on the other MKNOD succeeds. Now if a parallel write causes shard translator to send another MKNOD of the same shard (shortly after AFR releases entrylk from the first MKNOD), the file is created on the other replica too, although with a new gfid (since "gfid-req" that is passed now is a new UUID. This leads to a gfid-mismatch across the replicas. FIX: The solution is to not fail MKNOD (or any other entry fop for that matter that does posix_gfid_set()) if the .glusterfs link creation fails with EEXIST.

* ctime: Provide noatime optionKotresh HR2018-10-021-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Most of the applications are {c|m}time dependant and very few are atime dependant. So provide noatime option to not update atime when ctime feature is enabled. Also this option has to be enabled with ctime feature to avoid unnecessary self heal. Since AFR/EC reads data from single subvolume, atime is only updated in one subvolume triggering self heal.

* posix: disable open/read/write on special filesAmar Tumballi2018-09-061-0/+33
| | | | | | | | | | | | | | | | | | | In the file system, the responsibility w.r.to the block and char device files is related to only support for 'creating' them (using mknod(2)). Once the device files are created, the read/write syscalls for the specific devices are handled by the device driver registered for the specific major number, and depending on the minor number, it knows where to read from. Hence, we are at risk of reading contents from devices which are handled by the host kernel on server nodes. By disabling open/read/write on the device file, we would be safe with the bypass one can achieve from client side (using gfapi) Fixes: bz#1625096 Change-Id: I48c776b0af1cbd2a5240862826d3d8918601e47f Signed-off-by: Amar Tumballi <amarts@redhat.com>

| | | | | | | | | | | | posix_set_parent_ctime() unconditionally logs an error if consistent time attributes is not enabled. This log does not add any value, prints an incorrect errno & floods the log file. Hence nuking this log message in this patch.

* posix: check before removing stale symlinkRavishankar N2018-07-191-4/+8
| | | | | | | | | | | | | | BZ 1564071 complains of directories with missing gfid symlinks and corresponding "Found stale gfid handle" messages in the logs. Hence add a check to see if the symlink points to an actual directory before removing it. Note: Removing stale symlinks was added via commit 3e9a9c029fac359477fb26d9cc7803749ba038b2 Change-Id: I5d91fab8e5f3a621a9ecad4a1f9c898a3c2d346a Updates: bz#1564071 Signed-off-by: Ravishankar N <ravishankar@redhat.com>
* afr: switch lk_owner only when pre-op succeedsRavishankar N2018-07-181-5/+0
| | | | | | | | | | | | | | | | | | | Problem: In a disk full scenario, we take a failure path in afr_transaction_perform_fop() and go to unlock phase. But we change the lk-owner before that, causing unlock to fail. When mount issues another fop that takes locks on that file, it hangs. Fix: Change lk-owner only when we are about to perform the fop phase. Also fix the same issue for arbiters when afr_txn_arbitrate_fop() fails the fop. Also removed the DISK_SPACE_CHECK_AND_GOTO in posix_xattrop. Otherwise truncate to zero will fail pre-op phase with ENOSPC when the user is actually trying to freee up space.

* md-cache: Do not invalidate cache post set/remove xattrPoornima G2018-07-114-53/+85
| | | | | | | | | | | | | | | Since setxattr and removexattr fops cbk do not carry poststat, the stat cache was being invalidated in setxatr/remoxattr cbk. Hence the further lookup wouldn't be served from cache. To prevent this invalidation, md-cache is modified to get the poststat in set/removexattr_cbk in dict. Co-authored with Xavi Hernandez.

| | | | | | | | | | | | | When lseek is used with SEEK_DATA and SEEK_HOLE, it's expected that the last operation fails with ENXIO when offset is beyond the end of file. In this case it doesn't make sense to report this as an error log message. This patch reports ENXIO failure messages for seek fops in debug level instead of error level.

* ctime: Fix self heal of symlink in EC volumeKotresh HR2018-06-201-2/+0
| | | | | | | | | | | | | | | | | | | | Since IEEE Std 1003.1-2001 does not require any association of file times with symbolic links, there is no requirement that file times be updated by readlink() states [1]. stat on symlink file was generating a readlink fop on one of the subvolumes of ec set which in turn updates atime on that subvolume. This causes mdata xattr to be different across ec set and hence self heal fails. So based on [1], atime is no longer updated by readlink fop.

* posix/ctime: Fix differential ctime duing entry operationsKotresh HR2018-06-201-51/+60
| | | | | | | | | | | | | | | | | We should not be relying on backend file's time attributes to load the initial ctime time attribute structure. This is incorrect as each replica set would have witnessed the file creation at different times. For new file creation, ctime, atime and mtime should be same, hence initiate the ctime structure with the time from the frame. But for the files which were created before ctime feature is enabled, this is not accurate but still fine as the times would get eventually accurate. fixes: bz#1592275 Change-Id: I206a469c83ee7b26da2fe096ae7bf8ff5986ad67 Signed-off-by: Kotresh HR <khiremat@redhat.com>
