* libglusterfs/options: Add new member 'setkey' to xlator optionsKaushal M2017-11-152-2/+9
| | | | | | | | | | | | | | | | | The 'setkey' will be used as the key by GD2 when setting the option during volgen. 'setkey' also supports using varstrings. This is mainly to be used for options, which use a different key for 'volume set' and in volfiles. For eg. the 'auth.*' options of protocol/server. The protocol/server xlator has been updated to make use of this for the auth.allow and auth.reject options.

| | | | | | | | | | | | | | Issue: Glusterevents daemon hardcodes glusterd working directory even though it can be changed later in .vol file which causes breaks in the code. Fix: Use python subprocess module to get the working directory of gluster daemon in eventsapiconf.py.in.

* geo-rep: Fix data sync issue during hardlink, renameKotresh HR2017-11-141-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The data is not getting synced if master witnessed IO as below. 1. echo "test_data" > f1 2. ln f1 f2 3. mv f2 f3 4. unlink f1 On master, 'f3' exists with data "test_data" but on slave, only f3 exists with zero byte file without backend gfid link. Cause: On master, since 'f2' no longer exists, the hardlink is skipped during processing. Later, on trying to sync rename, since source ('f2') doesn't exist, dst ('f3') is created with same gfid. But in this use case, it succeeds but backend gfid would not have linked as 'f1' exists with the same gfid. So, rsync would fail with ENOENT as backend gfid is not linked with 'f3' and 'f1' is unlinked. Fix: On processing rename, if src doesn't exist on slave, don't blindly create dst with same gfid. The gfid needs to be checked, if it exists, hardlink needs to be created instead of mknod.

* libglusterfs/atomic: Improved atomic supportXavier Hernandez2017-11-146-97/+456
| | | | | | | | | | | | | | | | This patch solves a detection problem in configure.ac that prevented that compilation detects builtin __atomic or __sync functions. It also adds more atomic types and support for other atomic functions. An special case has been added to support 64-bit atomics on 32-bit systems. The solution is to fallback to the mutex solution only for 64-bit atomics, but smaller atomic types will still take advantage of builtins if available.

* extras: scripts to control CPU/MEMORY for any gluster daemon during runtimeMohit Agrawal2017-11-134-1/+254
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Sometime gluster daemons like glustershd can consume a lot of cpu and/ or memory if there is a large amount of data/ entries to be healed. Solution: Until we have some form of throttling/ QoS mechanisms built into gluster, we can use control groups for regulating cpu and memory of any gluster daemon using control-cpu-load.sh and control-mem.sh scripts respectively. Test: To test the control-cpu-load.sh script follow below procedure: 1) Setup distribute replica environment 2) Selfheal daemon off 3) Down one node from replica nodes 4) Create millions of files from mount point 5) Start down node 6) Check cpu usage for shd process in top command 7) Run script after provide shd pid with CPU quota value 8) Check again cpu usage for shd process in top command Note: control-mem.sh script can cap the memory usage of the process to the set limit, beyond which the process gets blocked. It resumes either when the memory usage comes down or if the limit is increased. BUG: 1496335 Change-Id: Id73c36b73ca600fa9f7905d84053d1e8633c996f Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>

* cluster/ec: Keep last written strip in in-memory cacheAshish Pandey2017-11-109-84/+525
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Consider an EC volume with configuration 4 + 2. The stripe size for this would be 512 * 4 = 2048. That means, 2048 bytes of user data stored in one stripe. Let's say 2048 + 512 = 2560 bytes are already written on this volume. 512 Bytes would be in second stripe. Now, if there are sequential writes with offset 2560 and of size 1 Byte, we have to read the whole stripe, encode it with 1 Byte and then again have to write it back. Next, write with offset 2561 and size of 1 Byte will again READ-MODIFY-WRITE the whole stripe. This is causing bad performance because of lots of READ request travelling over the network. There are some tools and scenario's where such kind of load is coming and users are not aware of that. Example: fio and zip Solution: One possible solution to deal with this issue is to keep last stripe in memory. This way, we need not to read it again and we can save READ fop going over the network. Considering the above example, we have to keep last 2048 bytes (maximum) in memory per file.

* mount/fuse: use fstat in getattr implementation if any opened fd is availableRaghavendra G2017-11-092-12/+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.

* glusterd: Coverity Issue FORWARD_NULL fixVishal Pandey2017-11-081-1/+1
| | | | | | | | | | | | | | | | | | Problems: According to Coverity Issue ID 207 issues are as follows- a-) Dereferencing "this" pointer without checking if it points to NULL. b-) The IF condition on line 1750 should check if any *one* of dict, this or peerinfo is NULL and not *all*. Fix: Replace the && operator with || to check if any *one* of this, dict or peerinfo is NULL and then execute out label.

* *.pc: Fix include path in CflagsAndrea Bolognani2017-11-085-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The include path in glusterfs-api.pc looks like -I${includedir}/glusterfs However, client code will include the glusterfs headers using #include <glusterfs/api/glfs.h> rather than #include <api/glfs.h> which makes the "/glusterfs" part entirely unnecessary. More importantly, on some platforms such as FreeBSD, the header files for glusterfs will be installed in /usr/local/include, which is *not* part of the compiler's default include path, so compilation will fail with something like fatal error: 'glusterfs/api/glfs.h' file not found #include <glusterfs/api/glfs.h> ^~~~~~~~~~~~~~~~~~~~~~ The fix is to simply drop the extra "/glusterfs". The same change is applied to other *.pc files as well, althought I haven't actually tested those. A test program (gfapi-load-volfile) and the glfsxmp example application were using the wrong include paths, so they had to be fixed as well.
