| | | | | | | | | | vector count is reduced to 1 but it is not reflected at the time of winding the call. This leads to crash when short-writes are done using error-gen.

* glusterd: stop stale bricks during handshaking in brick mux modeAtin Mukherjee2019-08-254-9/+55
| | | | | | | | | | | | | | | | | | | | This patch addresses two problems: 1. During friend handshaking, if a volume is imported due to change in the version, the old bricks were not stopped which would lead to a situation where bricks will run with old volfiles. 2. As part of attaching shd service in glusterd_attach_svc, there might be a case that the volume for which we're attempting to attach a shd service might become stale and in the process of deletion and hence in every retrials (if the rpc connection isn't ready) check for the existance of the volume and then only attempt the further attach request.

* glusterd: Add warning and abort in case of failures in migration during ↵heal-infoVishal Pandey2019-08-251-0/+11
| | | | | | | | | | | | | | | | | | remove-brick commit Problem - Currently remove-brick commit goes through even though there were files that failed to migrate or were skipped. There is no warning raised to the user. Solution- Add a check in the remove brick staging phase to verify if the status of the rebalnce process is complete but there has been failures or some skipped files while migration, In this case user will be given a warning and remove-brick commit. User will need to use the force option to remove the bricks. Fixes: bz#1514683 Signed-offby- Vishal Pandey <vpandey@redhat.com> Change-Id: I014d0f0afb4b2fac35ab0de52227f98dbae079d5

* performance/md-cache: Do not skip caching of null character xattr valuesAnoop C S2019-08-202-20/+23
| | | | | | | | | | | | | | | | | | | | | Null character string is a valid xattr value in file system. But for those xattrs processed by md-cache, it does not update its entries if value is null('\0'). This results in ENODATA when those xattrs are queried afterwards via getxattr() causing failures in basic operations like create, copy etc in a specially configured Samba setup for Mac OS clients. On the other side snapview-server is internally setting empty string("") as value for xattrs received as part of listxattr() and are not intended to be cached. Therefore we try to maintain that behaviour using an additional dictionary key to prevent updation of entries in getxattr() and fgetxattr() callbacks in md-cache.

* posix/ctime: Fix race during lookup ctime xattr healKotresh HR2019-08-011-18/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Ctime heals the ctime xattr ("trusted.glusterfs.mdata") in lookup if it's not present. In a multi client scenario, there is a race which results in updating the ctime xattr to older value. e.g. Let c1 and c2 be two clients and file1 be the file which doesn't have the ctime xattr. Let the ctime of file1 be t1. (from backend, ctime heals time attributes from backend when not present). Now following operations are done on mount c1 -> ls -l /mnt/file1 | c2 -> ls -l /mnt/file1;echo "append" >> /mnt/file1; The race is that the both c1 and c2 didn't fetch the ctime xattr in lookup, so both of them tries to heal ctime to time 't1'. If c2 wins the race and appends the file before c1 heals it, it sets the time to 't1' and updates it to 't2' (because of append). Now c1 proceeds to heal and sets it to 't1' which is incorrect. Solution: Compare the times during heal and only update the larger time. This is the general approach used in ctime feature but got missed with healing legacy files. fixes: bz#1734299 Change-Id: I930bda192c64c3d49d0aed431ce23d3bc57e51b7 Signed-off-by: Kotresh HR <khiremat@redhat.com>
* cluster/ec: Create heal task with heal process idAshish Pandey2019-07-301-1/+19
| | | | | | | | | | | | | | | | | | | Problem: ec_data_undo_pending calls syncop_fxattrop->SYNCOP without a frame. In this case SYNCOP gets the frame of the task. However, when we create a synctask for heal we provide frame as NULL. Now, if the read-only feature is ON, it will receive the process ID of the shd as 0 and will consider that it as not an internal process. This will prevent healing of a file with "Read-only file system" error message log. Solution: While launching heal, create a synctask using frame and set process id of the SHD which is -6.

* cluster/ec: Fix reopen flags to avoid misbehaviorPranith Kumar K2019-07-302-3/+8
| | | | | | | | | | | | | | | | | | | | | | | Problem: when a file needs to be re-opened O_APPEND and O_EXCL flags are not filtered in EC. - O_APPEND should be filtered because EC doesn't send O_APPEND below EC for open to make sure writes happen on the individual fragments instead of at the end of the file. - O_EXCL should be filtered because shd could have created the file so even when file exists open should succeed - O_CREAT should be filtered because open happens with gfid as parameter. So open fop will create just the gfid which will lead to problems. Fix: Filter out these two flags in reopen.

* event: rename event_XXX with gf_ prefixedXiubo Li2019-07-296-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I hit one crash issue when using the libgfapi. In the libgfapi it will call glfs_poller() --> event_dispatch() in file api/src/glfs.c:721, and the event_dispatch() is defined by libgluster locally, the problem is the name of event_dispatch() is the extremly the same with the one from libevent package form the OS. For example, if a executable program Foo, which will also use and link the libevent and the libgfapi at the same time, I can hit the crash, like: kernel: glfs_glfspoll[68486]: segfault at 1c0 ip 00007fef006fd2b8 sp 00007feeeaffce30 error 4 in libevent-2.0.so.5.1.9[7fef006ed000+46000] The link for Foo is: lib_foo_LADD = -levent $(GFAPI_LIBS) It will crash. This is because the glfs_poller() is calling the event_dispatch() from the libevent, not the libglsuter. The gfapi link info : GFAPI_LIBS = -lacl -lgfapi -lglusterfs -lgfrpc -lgfxdr -luuid If I link Foo like: lib_foo_LADD = $(GFAPI_LIBS) -levent It will works well without any problem. And if Foo call one private lib, such as handler_glfs.so, and the handler_glfs.so will link the GFAPI_LIBS directly, while the Foo won't and it will dlopen(handler_glfs.so), then the crash will be hit everytime. The link info will be: foo_LADD = -levent libhandler_glfs_LIBADD = $(GFAPI_LIBS) I can avoid the crash temporarily by linking the GFAPI_LIBS in Foo too like: foo_LADD = $(GFAPI_LIBS) -levent libhandler_glfs_LIBADD = $(GFAPI_LIBS) But this is ugly since the Foo won't use any APIs from the GFAPI_LIBS. And in some cases when the --as-needed link option is added(on many dists it is added as default), then the crash is back again, the above workaround won't work.

* glusterd: write voldir once in glusterd-store and don't attempt again.Yaniv Kaul2019-07-291-29/+16
| | | | | | | | | | | | | | | | | | glusterd_store_brickinfos() is calling per each brick the function glusterd_store_brickinfo(). In it, we call: ret = glusterd_store_create_brick_dir(volinfo); However, volinfo is the same for all those bricks - no need to again and again call it (which tries to mkdir that dir). We can do it once above the loops in glusterd_store_brickinfos() While at, combine two similar functions that write additional dirs.
