* features/shard: Make lru limit of inode list configurableKrutika Dhananjay2018-07-232-4/+21
| | | | | | | | | | | | | | | Currently this lru limit is hard-coded to 16384. This patch makes it configurable to make it easier to hit the lru limit and enable testing of different cases that arise when the limit is reached. The option is features.shard-lru-limit. It is by design allowed to be configured only in init() but not in reconfigure(). This is to avoid all the complexity associated with eviction of least recently used shards when the list is shrunk.

* features/shard: Introducing ".shard/.remove_me" for atomic shard deletion ↵Krutika Dhananjay2018-06-134-421/+1040
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | (part 1) PROBLEM: Shards are deleted synchronously when a sharded file is unlinked or when a sharded file participating as the dst in a rename() is going to be replaced. The problem with this approach is it makes the operation really slow, sometimes causing the application to time out, especially with large files. SOLUTION: To make this operation atomic, we introduce a ".remove_me" directory. Now renames and unlinks will simply involve two steps: 1. creating an empty file under .remove_me named after the gfid of the file participating in unlink/rename 2. carrying out the actual rename/unlink A synctask is created (more on that in part 2) to scan this directory after every unlink/rename operation (or upon a volume mount) and clean up all shards associated with it. All of this happens in the background. The task takes care to delete the shards associated with the gfid in .remove_me only if this gfid doesn't exist in backend, ensuring that the file was successfully renamed/unlinked and its shards can be discarded now safely.

* features/shard: Remove ctx from LRU in shard_forgetPranith Kumar K2017-06-301-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: There is a race when the following two commands are executed on the mount in parallel from two different terminals on a sharded volume, which leads to use-after-free. Terminal-1: while true; do dd if=/dev/zero of=file1 bs=1M count=4; done Terminal-2: while true; do cat file1 > /dev/null; done In the normal case this is the life-cycle of a shard-inode 1) Shard is added to LRU when it is first looked-up 2) For every operation on the shard it is moved up in LRU 3) When "unlink of the shard"/"LRU limit is hit" happens it is removed from LRU But we are seeing a race where the inode stays in Shard LRU even after it is forgotten which leads to Use-after-free and then some memory-corruptions. These are the steps: 1) Shard is added to LRU when it is first looked-up 2) For every operation on the shard it is moved up in LRU Reader-handler Truncate-handler 1) Reader handler needs shard-x to be read. 1) Truncate has just deleted shard-x 2) In shard_common_resolve_shards(), it does inode_resolve() and that leads to a hit in LRU, so it is going to call __shard_update_shards_inode_list() to move the inode to top of LRU 2) shard-x gets unlinked from the itable and inode_forget(inode, 0) is called to make sure the inode can be purged upon last unref 3) when __shard_update_shards_inode_list() is called it finds that the inode is not in LRU so it adds it back to the LRU-list Both these operations complete and call inode_unref(shard-x) which leads to the inode getting freed and forgotten, even when it is in Shard LRU list. When more inodes are added to LRU, use-after-free will happen and it leads to undefined behaviors. Fix: I see that the inode can be removed from LRU even by the protocol layers like gfapi/gNFS when LRU limit is reached. So it is better to add a check in shard_forget() to remove itself from LRU list if it exists.

| | | | | | | | | | | | | | | | | | | | | When a file is opened with append, all writes are appended at the end of file irrespective of the offset given in the write syscall. This needs to be considered in shard size update function and also for choosing which shard to write to. At the moment shard piggybacks on queuing from write-behind xlator for ordering of the operations. So if write-behind is disabled and two parallel appending-writes come both of which can increase the file size beyond shard-size the file will be corrupted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | shard's writev implementation, as part of identifying presence of participant shards that aren't in memory, first sends an MKNOD on these shards, and upon EEXIST error, looks up the shards before proceeding with the writes. The VM corruption was caused when the following happened: 1. DHT had n subvolumes initially. 2. Upon add-brick + fix-layout, the layout of .shard changed although the existing shards under it were yet to be migrated to their new hashed subvolumes. 3. During this time, there were writes on the VM falling in regions of the file whose corresponding shards were already existing under .shard. 4. Sharding xl sent MKNOD on these shards, now creating them in their new hashed subvolumes although there already exist shard blocks for this region with valid data. 5. All subsequent writes were wound on these newly created copies. The net outcome is that both copies of the shard didn't have the correct data. This caused the affected VMs to be unbootable. FIX: For want of better alternatives in DHT, the fix changes shard fops to do a LOOKUP before the MKNOD and upon EEXIST error, perform another lookup.

* features/shard: Pass the correct iatt for cache invalidationKrutika Dhananjay2017-03-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This fixes a performance issue with shard which was causing the translator to trigger unusually high number of lookups for cache invalidation even when there was no modification to the file. In shard_common_stat_cbk(), it is local->prebuf that contains the aggregated size and block count as opposed to buf which only holds the attributes for the physical copy of base shard. Passing buf for inode_ctx invalidation would always set refresh to true since the file size in inode ctx contains the aggregated size and would never be same as @buf->ia_size. This was leading to every write/read being preceded by a lookup on the base shard even when the file underwent no modification.

* features/shard: Fix EIO error on add-brickKrutika Dhananjay2017-02-232-19/+154
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DHT seems to link inode during lookup even before initializing inode ctx with layout information, which comes after directory healing. Consider two parallel writes. As part of the first write, shard sends lookup on .shard which in its return path would cause DHT to link .shard inode. Now at this point, when a second write is wound, inode_find() of .shard succeeds and as a result of this, shard goes to create the participant shards by issuing MKNODs under .shard. Since the layout is yet to be initialized, mknod fails in dht call path with EIO, leading to VM pauses. The fix involves shard maintaining a flag to denote whether a fresh lookup on .shard completed one network trip. If it didn't, all inode_find()s in fop path will be followed by a lookup before proceeding with the next stage of the fop. Big thanks to Raghavendra G and Pranith Kumar K for the RCA and subsequent inputs and feedback on the patch.

* features/shard: Fill loc.pargfid too for named lookups on individual shardsKrutika Dhananjay2016-11-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a sharded volume when a brick is replaced while IO is going on, named lookup on individual shards as part of read/write was failing with ENOENT on the replaced brick, and as a result AFR initiated name heal in lookup callback.

Rewrite the make rules to do what xdrgen does. Now we can get rid of xdrgen. Note 1. netbsd6's sed doesn't do -i. Why are we still running smoke tests on netbsd6 and not netbsd7? We barely support netbsd7 as it is. Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with libglusterfs? A cut-and-paste mistake? It has no references to symbols in libglusterfs. Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_ regex that matches the same lines as the _extended_ regex "/#(ifndef|define|endif)/". To match the extended regex sed needs to be run with -r on Linux; with -E on *BSD. However NetBSD's and FreeBSD's sed helpfully also provide -r for compatibility. Using a basic regex avoids having to use a kludge in order to run sed with the correct option on OS X. Note 4. Not copying the bit of xdrgen that inserts copyright/license boilerplate. AFAIK it's silly to pretend that machine generated files like these can be copyrighted or need license boilerplate. The XDR source files have their own copyright and license; and their copyrights are bound to be more up to date than old boilerplate inserted by a script. From what I've seen of other Open Source projects -- e.g. gcc and its C parser files generated by yacc and lex -- IIRC they don't bother to add copyright/license boilerplate to their generated files. It appears that it's a long-standing feature of make (SysV, BSD, gnu) for out-of-tree builds to helpfully pretend that the source files it can find in the VPATH "exist" as if they are in the $cwd. rpcgen doesn't work well in this situation and generates files with "bad" #include directives. E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`, you get an #include directive in the generated .c file like this: ... #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h" ... which (obviously) results in compile errors on out-of-tree build because the (generated) header file doesn't exist at that location. Compared to `rpcgen ./glusterfs3-xdr.x` where you get: ... #include "glusterfs3-xdr.h" ... Which is what we need. We have to resort to some Stupid Make Tricks like the addition of various .PHONY targets to work around the VPATH "help". Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/... looks exactly like -I$(top_srcdir)/rpc/xdr/... Don't be fooled though. And don't delete the -I$(top_builddir)/rpc/xdr/... bits Change-Id: Iba6ab96b2d0a17c5a7e9f92233993b318858b62e BUG: 1330604 Signed-off-by: Kaleb S KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/14085 Tested-by: Niels de Vos <ndevos@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com>

| | | | | | | | | | | | | | | | | | | With files opened with o-direct, the expectation is that the IO performed on the fds is byte aligned wrt the sector size of the underlying device. With files getting sharded, a single write from the application could be broken into more than one write falling on different shards which _might_ cause the original byte alignment property to be lost. To get around this, shard translator will send fsync on odirect writes to emulate o-direct-like behavior in the backend.
