* glusterfs: During reconfigure set log-level per xlator levelMohit Agrawal2018-10-241-1/+31
| | | | | | | | | | | | | | | | Problem: In brick_mux environment, while a user has enabled brick-log-level for anyone volume, it automatically enables for other volumes also those are attached with same brick. Solution: A log-level option is automatically enabled for other volumes because log-level saved in glusterfsd_ctx and ctx is common for volumes those are attached with same brick. To resolve it set log level for all children xlator's at the time of the graph reconfigure at io-stat xlator.

* cluster/afr : Check for UP bricks before starting healAshish Pandey2018-10-243-1/+19
| | | | | | | | | | | | | | | | | | | | | | | Problem: Currently for replica volume, even if only one brick is UP SHD will keep crawling index entries even if it can not heal anything. In thin-arbiter volume which is also a replica 2 volume, this causes inode lock contention which in turn sends upcall to all the clients to release notify locks, even if it can not do anything for healing. This will slow down the client performance and kills the purpose of keeping in memory information about bad brick. Solution: Before starting heal or even crawling, check if sufficient number of children are UP and available to check and heal entries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: https://review.gluster.org/#/c/glusterfs/+/21427/ seems to be failing this .t spuriously.

* storage/posix: Do not fail entry creation fops if gfid handle already existsKrutika Dhananjay2018-10-182-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The #include "uuid.h" left over from using .../contrib/uuid is debatably incorrect now that we use the "system header" file /usr/include/uuid/uuid.h from libuuid-devel. Unfortunately this is complicated by things like FreeBSD having its own /usr/include/uuid.h, and the e2fsprogs-libuuid uuid.h in installed - as most third-party packages in FreeBSD are - in /usr/local as /usr/local/include/uuid/uuid.h With a system header file it should at least be #include <uuid.h>, and even better as #include <uuid/uuid.h>, much like the way <sys/types.h> and <net/if.h> are included. Using #include <uuid/uuid.h> guarantees not getting the /usr/include/uuid.h on FreeBSD, but clang/cc knows to find "system" header files like this in /usr/local/include; with or without the -I/... from uuid.pc. Also using #include "uuid.h" leaves the compiler free to find a uuid.h from any -I option it might be passed. (Fortunately we don't have any at this time.) As we now require libuuid-devel or e2fsprogs-libuuid and configure will exit with an error if the uuid.pc file doesn't exist, the HAVE_LIBUUID (including the #elif FreeBSD) tests in compat-uuid.h are redundant. We are guaranteed to have it, so testing for it is a bit silly IMO. It may also break building third party configure scripts if they omit defining it. (Just how hard do we want to make things for third party developers?) Change-Id: I7317f63c806281a5d27de7d3b2208d86965545e1 updates: bz#1193929 Signed-off-by: Kaleb S. KEITHLEY <kkeithle@redhat.com>
* features/shard: Hold a ref on base inode when adding a shard to lru listKrutika Dhananjay2018-10-166-21/+140
| | | | | | | | | | | | | | | | | | | | | | | | | In __shard_update_shards_inode_list(), previously shard translator was not holding a ref on the base inode whenever a shard was added to the lru list. But if the base shard is forgotten and destroyed either by fuse due to memory pressure or due to the file being deleted at some point by a different client with this client still containing stale shards in its lru list, the client would crash at the time of locking lru_base_inode->lock owing to illegal memory access. So now the base shard is ref'd into the inode ctx of every shard that is added to lru list until it gets lru'd out. The patch also handles the case where none of the shards associated with a file that is about to be deleted are part of the LRU list and where an unlink at the beginning of the operation destroys the base inode (because there are no refkeepers) and hence all of the shards that are about to be deleted will be resolved without the existence of a base shard in-memory. This, if not handled properly, could lead to a crash. Change-Id: Ic15ca41444dd04684a9458bd4a526b1d3e160499 updates: bz#1605056 Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com>
* libglusterfs/dict: Add sizeof()-1 variants of dict functionsPranith Kumar K2018-10-159-41/+52
| | | | | | | | | | | One needs to be very careful about giving same key for the key and SLEN(key) arguments in dict_xxxn() functions.

* glusterd/geo-rep: Fix memory corruptionKotresh HR2018-10-122-3/+3
| | | | | | | | | | | | | | | | | | | | Problem and Analysis: The length of canonical format of uuid is 36 but 'GF_UUID_BUF_SIZE 50' was being used everywhere. glusterd/geo-rep code was earlier using strncpy, but recently changes to memcpy with the drive to avoid strncpys. This leads to memory corruption and glusterd is crashing without a core with geo-rep creation with ASAN build. Fix: 'GF_UUID_BUF_SIZE 37' (+ 1 for NULL byte) And change geo-rep to use UUID_CANONICAL_FORM_LEN instead Updates: bz#1633930 Change-Id: Ibd347d542b92e64a96ce06780cda643557233bc7 Signed-off-by: Kotresh HR <khiremat@redhat.com>

* core: glusterfsd keeping fd open in index xlatorMohit Agrawal2018-10-124-25/+94
| | | | | | | | | | | | | | | | | | | | | | Problem: At the time of processing GF_EVENT_PARENT_DOWN at brick xlator, it forwards the event to next xlator only while xlator ensures no stub is in progress. At io-thread xlator it decreases stub_cnt before the process a stub and notify EVENT to next xlator Solution: Introduce a new counter to save stub_cnt and decrease the counter after process the stub completely at io-thread xlator. To avoid brick crash at the time of call xlator_mem_cleanup move only brick xlator if detach brick name has found in the graph Note: Thanks to pranith for sharing a simple reproducer to reproduce the same fixes bz#1637934 Change-Id: I1a694a001f7a5417e8771e3adf92c518969b6baa Signed-off-by: Mohit Agrawal <moagrawal@redhat.com>

* socket: use accept4/paccept for nonblocking socketKrishnan Parthasarathi2018-10-125-16/+81
| | | | | | | | | | | | | | | | | This reduces the no. of syscalls on Linux systems from 2, accept(2) and fcntl(2) for setting O_NONBLOCK, to a single accept4(2). On NetBSD, we have paccept(2) that does the same, if we leave signal masking aside. Added sys_accept which accepts an extra flags argument than accept(2). This would opportunistically use accept4/paccept as available. It would fallback to accept(2) and fcntl(2) otherwise. While at this, the patch sets FD_CLOEXEC flag on the accepted socket fd.
