* xlators/mgmt/glusterd/src/glusterd-volgen.c: use dict_ new functionsYaniv Kaul2018-12-051-237/+230
| | | | | | | | | | | | | | | In a previous patch (https://review.gluster.org/20769) we've added the key length to be passed to dict_* funcs, to remove the need to strlen() it. This patches makes use of these functions over this whole file. Please review carefully, as there are many many changes there.

* configure.ac: fix option to stop automake aborting on pointless errorEli Schwartz2018-12-042-2/+2
| | | | | | | | | | | | | | | | | | | | | | glusterfs does not follow the GNU coding standards and therefore must use the "foreign" strictness. Without this, autoreconf -fi would fail to execute successfully because automake returned non-zero. This change ensures that people using autoreconf, the GNU preferred invocation method for the autotools build system, can successfully set up the build. Remove the pointless --foreign argument from the autogen.sh invocation of automake. Not only is configure.ac the preferred way to define such options (rather than handwritten, piecemeal invocations of every tool in the autotools toolchain), it was never needed in the autogen.sh as that script provides no error handling at all and always (incorrectly) returns successfully as long as autotools itself is installed (no matter how broken glusterfs itself is).

* Do not blindly add volume share section to smb.confMilan Zink2018-12-042-5/+26
| | | | | | | | | | | | | With this change, by default GlusterFS volume share section will no longer be added to smb.conf for client access unless user.cifs or user.smb volume set options are enabled. This also fixes the hook script to check for presence of all configuration possibilities for those volume set options like 'enable' or 'on'.

* glusterd: migrating profile commands to mgmt_v3 frameworkSanju Rakonde2018-12-045-23/+244
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Current profile commands use the op_state machine framework. Porting it to use the mgmt_v3 framework. The following tests were performed on the patch: case 1: 1. On a 3 node cluster, created and started 3 volumes 2. Mounted all the three volumes and wrote some data 3. Started profile operation for all the volumes 4. Ran "gluster v status" from N1, "gluster v profile <volname1> info" form N2, "gluster v profile <volname2> info" from N3 simultaneously in a loop for around 10000 times 5. Didn't find any cores generated. case 2: 1. Repeat the steps 1,2 and 3 from case 1. 2. Ran "gluster v status" from N1, "gluster v profile <volname1> info" form N2(terminal 1), "gluster v profile <volname2> info" from N2(terminal 2) simultaneously in a loop. 3. No cores were generated. fixes: bz#1654181 Change-Id: I83044cf5aee3970ef94066c89fcc41783ed468a6 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

Hence was failing in gfid-access layer. Fix: It appears that the calculating lenght properly fixes this issue. But it will cause issues in other places in 'python2' and not in 'python3'. So encoding and decoding each required string to make geo-rep compatible with both 'python2' and 'python3' is a nightmare and is not fool proof. Hence kept 'python2' code as is with out encode/decode and applied encode/decode only to 'python3' Added non-ascii filename tests to regression fixes: bz#1650893 Change-Id: I35cfaf848e07b1a0b5cb93c01b98b472f08271a6 Signed-off-by: Kotresh HR <khiremat@redhat.com>
* rpc: bump up server.event-threadsMilind Changire2018-12-043-3/+3
| | | | | | | | | | | | | | | Problem: A single event-thread causes performance issues in the system. Solution: Bump up event-threads to 2 to make the system more performant. This helps in making the system more responsive and helps avoid the ping-timer-expiry problem as well. However, setting the event-threads to 2 is not the only thing required to avoid ping-timer-expiry issues.

* rpc: check if fini is there before calling itRaghavendra Bhat2018-12-041-1/+3
| | | | | | | | | | | | | | | The rpc_transport_t structure is allocated and filled in the rpc_transport_load function. If filling the fileds of the rpc structure fails, then in the failure handling the structure is freed by rpc_transport_cleanup. There, it unconditionally calls fini. But, if the failure handling was invoked because of any failure in between the allocation of rpc_transport_t and filling the transport->fini (including the failure to fill fini ()), then rpc_transport_cleanup can lead to a segfault.

* features/bitrot: compare the signature with proper lengthRaghavendra Bhat2018-12-032-8/+14
| | | | | | | | | | | | | | | | | | | | | * 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.

* clang: Fix clang warnings in snapview-server.cShyamsundarR2018-11-291-12/+0
| | | | | | | | | | | | | | | | | | | | | The warning by clang is due to the fact that we check for frame->root to be NULL, but in stack unwind, we ignore the same. If frame is non-NULL then frame->root is non-NULL as frame creation ensures this. Further, across the code we do not check both frame and frame->root for validity. Hence to fix these clang issues, removing the check for frame->root in the various functions. NOTE: Initially clang reported 14 issues in the file, but post commit 6eabefe6 the number reduced to 4, unsure why as that commit does not address this issue.

* libglusterfs/src/dict.c : consistent initialization of parameters.Yaniv Kaul2018-11-271-60/+29
| | | | | | | | | | | | | | | | Some were assigned NULL, for no good reason, some were assigned proper initial value. Made them all consistent, as much as possible, to be assigned reasonable initial values. No expected functional changes (and I also assume the compiler already did most of this work behind the scenes anyway, so no performance implications either).

* glfsheal: add a '--nolog' flagRavishankar N2018-11-264-17/+56
| | | | | | | | | | | | | | | | | | | | | ....and if set, change the log level to GF_LOG_NONE. This is useful for monitoring applications which invoke the heal info set of commands once every minute, leading to un-necessary glfsheal* logs in /var/log/glusterfs/. For example, we can now run `gluster volume heal <VOLNAME> info --nolog` `gluster volume heal <VOLNAME> info split-brain --nolog` etc. The default log level is still retained at GF_LOG_INFO. The patch also changes glfsheal internally to accept '--xml' instead of 'xml'. Note: The --nolog flag is *not* displayed in the help anywhere, for the sake of consistency in how the other flags are not displayed anywhere in the help. fixes: bz#1643519 Change-Id: Ia08b6aa6e4a0548379db7e313dd4411ebc66f206 Signed-off-by: Ravishankar N <ravishankar@redhat.com>

* coding-standard: memset before string functions similar to sprintf/snprintf etcSusant Palai2018-11-261-0/+31
| | | | | | | | | | | | | String functions like sprintf/snprintf/vprintf etc terminates the string with a null character. This makes meset redundant and also incurs some performance penalty. Also added a comment about using GF_MALLOC instead of GF_CALLOC for allocating buffer for strings, targeted by such functions.

* libglusterfs: fix memory corruption caused by per-thread mem poolsXavi Hernandez2018-11-261-57/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a race in the per-thread memory pool management that could lead to memory corruption. The race appeared when the following sequence of events happened: 1. Thread T1 allocated a memory object O1 from its own private pool P1 2. T1 terminates and P1 is marked to be destroyed 3. The mem-sweeper thread is woken up and scans all private pools 4. It detects that P1 needs to be destroyed and starts releasing the objects from hot and cold lists. 5. Thread T2 releases O1 6. O1 is added to the hot list of P1 The problem happens because steps 4 and 6 are protected by diferent locks, so they can run concurrently. This means that both T1 and T2 are modifying the same list at the same time, potentially causing corruption. This patch fixes the problem using the following approach: 1. When an object is released, it's only returned to the hot list of the corresponding memory pool if it's not marked to be destroyed. Otherwise the memory is released to the system. 2. Object release and mem-sweeper thread synchronize access to the deletion mark of the memory pool to prevent simultaneous access to the list. Some other minor adjustments are made to reduce the lengths of the locked regions.

* geo-rep: Fix permissions with non-root setupKotresh HR2018-11-261-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In non-root fail-over/fail-back(FO/FB), when slave is promoted as master, the session goes to 'Faulty' Cause: The command 'gluster-mountbroker <mountbroker-root> <group>' is run as a pre-requisite on slave in non-root setup. It modifies the permission and group of following required directories and files recursively [1] /var/lib/glusterd/geo-replication [2] /var/log/glusterfs/geo-replication-slaves In a normal setup, this is executed on slave node and hence doing it recursively is not an issue on [1]. But when original master becomes slave in non-root during FO/FB, it contains ssh public keys and modifying permissions on them causes geo-rep to fail with incorrect permissions. Fix: Don't do permission change recursively. Fix permissions for required files. fixes: bz#1651498 Change-Id: I68a744644842e3b00abc26c95c06f123aa78361d Signed-off-by: Kotresh HR <khiremat@redhat.com>
* gfapi: Offload callback notifications to synctaskSoumya Koduri2018-11-264-10/+419
| | | | | | | | | | | | | | | | | | | | | | Upcall notifications are received from server via epoll and same thread is used to forward these notifications to the application. This may lead to deadlock and hang in the following scenario. Consider if as part of handling these callbacks, application has to do some operations which involve sending I/Os to gfapi stack which inturn have to wait for epoll threads to receive repsonse. Thus this may lead to deadlock if all the epoll threads are waiting to complete these callback notifications. To address it, instead of using epoll thread itself, make use of synctask to send those notificaitons to the application.
