* protocol: Fix 4.0 client, parsing older iatt in dictShyamsundarR2018-03-111-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a mixed mode cluster involving 4.0 and older 3.x bricks, if clients are newer, then the iatt encoded in the dictionary can be of the older iatt format, which a newer client will map incorrectly to the newer structure. This causes failures in FOPs that depend on this iatt for some functionality (seen in mkdir operations failing as EIO, when DHT hits its internal setxattr call). The fix provided is to convert the iatt in the dict, based on which RPC version is used to communicate with the server. IOW, this is the reverse of change in commit "b966c7790e" Tested using a mixed mode cluster (i.e bricks in 3.12 and 4.0 versions) and a mixed set of clients, 3.12 and 4.0 clients. There is no regression test provided, as this needs a mixed mode cluster to test and validate. >Change-Id: I454e54651ca836b9f7c28f45f51d5956106aefa9 >BUG: 1554053 >Signed-off-by: ShyamsundarR <srangana@redhat.com> Change-Id: I454e54651ca836b9f7c28f45f51d5956106aefa9 BUG: 1554077 Signed-off-by: ShyamsundarR <srangana@redhat.com> Signed-off-by: Raghavendra G <rgowdapp@redhat.com>
* protocol: Added iatt conversion to older formatShyamsundarR2018-03-111-0/+30
| | | | | | | | | | | | | | | | Added iatt conversion to an older format, when dealing with older RPC versions. This enables iatt structure conformance when dealing with older clients. This helps fix rolling upgrade from 3.x versions to 4.0 version of gluster by sending the right iatt in the dictionary when DHT requests the same.

| | | | | | | | | | | | | | | | | | | | | | With this patchset, some major things are changed in XDR, mainly: * Naming: Instead of gfs3/gfs4 settle for gfx_ for xdr structures * add iattx as a separate structure, and add conversion methods * the *_rsp structure is now changed, and is also reduced in number (ie, no need for different strucutes if it is similar to other response). * use proper XDR methods for sending dict on wire. Also, with the change of xdr structure, there are changes needed outside of xlator protocol layer to handle these properly. Mainly because the abstraction was broken to support 0-copy RDMA with payload for write and read FOP. This made transport layer know about the xdr payload, hence with the change of xdr payload structure, transport layer needed to know about the change.

* rio/everywhere: add icreate/namelink fopSusant Palai2017-12-051-0/+234
| | | | | | | | | | | | | | | | | | | | | icreate creates inode, while namelink links the basename to it's parent gfid. For now mkdir is the primary user of these fops. Better distribution is acheived by creating the inode on ,(say) mds1 and linking the basename to it's parent gfid on mds2. The inode serves readdirp, stat etc. More details about the fops are present at: https://review.gluster.org/#/c/13395/3/design/DHT2/DHT2_Icreate_Namelink_Notes.md This backport of three patches from experimental branch. 1- https://review.gluster.org/#/c/18085/ 2- https://review.gluster.org/#/c/18086/ 3- https://review.gluster.org/#/c/18094/ Updates gluster/glusterfs#243 Change-Id: I1bd3d5a441a3cfab1acfeb52f15c6c867d362592 Signed-off-by: Susant Palai <spalai@redhat.com>

* glusterfsd: allow subdir mountAmar Tumballi2017-08-041-41/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes: 1. Take subdir mount option in client (mount.gluster / glusterfsd) 2. Pass the subdir mount to server-handshake (from client-handshake) 3. Handle subdir-mount dir's lookup in server-first-lookup and handle all fops resolution accordingly with proper gfid of subdir 4. Change the auth/addr module to handle the multiple subdir entries in option, and valid parsing. How to use the feature: `# mount -t glusterfs $hostname:/$volname/$subdir /$mount_point` Or `# mount -t glusterfs $hostname:/$volname -osubdir_mount=$subdir /$mount_point` Option can be set like: `# gluster volume set <volname> auth.allow "/subdir1(192.168.1.*),/(192.168.10.*),/subdir2(192.168.8.*)"` Updates #175 Change-Id: I7ea57f76ddbe6c3862cfe02e13f89e8a39719e11 Signed-off-by: Amar Tumballi <amarts@redhat.com> Reviewed-on: https://review.gluster.org/17141 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>
* program/GF-DUMP: Shield ping processing from traffic to GlusterfsRaghavendra G2017-07-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Program Since poller thread bears the brunt of execution till the request is handed over to io-threads, poller thread experiencies lock contention(s) in the control flow till io-threads, which slows it down. This delay invariably affects reading ping requests from network and responding to them, resulting in increased ping latencies, which sometimes results in a ping-timer-expiry on client leading to disconnect of transport. So, this patch aims to free up poller thread from executing code of Glusterfs Program. We do this by making * Glusterfs Program registering itself asking rpcsvc to execute its actors in its own threads. * GF-DUMP Program registering itself asking rpcsvc to _NOT_ execute its actors in its own threads. Otherwise program's ownthreads become bottleneck in processing ping traffic. This means that poller thread reads a ping packet, invokes its actor and hands the response msg to transport queue.

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-4/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.

* compound fops: Fix file corruption issueKrutika Dhananjay2016-10-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Address of a local variable @args is copied into state->req in server3_3_compound (). But even after the function has gone out of scope, in server_compound_resume () this pointer is accessed and dereferenced. This patch fixes that. 2. Compound fops, by virtue of NOT having a vector sizer (like the one writev has), ends up having both the header and the data (in case one of its member fops is WRITEV) in the same hdr_iobuf. This buffer was not being preserved through the lifetime of the compound fop, causing it to be overwritten by a parallel write fop, even when the writev associated with the currently executing compound fop is yet to hit the desk, thereby corrupting the file's data. This is fixed by associating the hdr_iobuf with the iobref so its memory remains valid through the lifetime of the fop. 3. Also fixed a use-after-free bug in protocol/client in compound fops cbk, missed by Linux but caught by NetBSD. Finally, big thanks to Pranith Kumar K and Raghavendra Gowdappa for their help in debugging this file corruption issue.

So send a first lookup when the inode table is created * When sending lookup on root, new inode is created, we need to use itable->root instead Change-Id: Iff2eeaa1a89795328833a7761789ef588f11218f BUG: 1320818 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/13837 Smoke: Gluster Build System <jenkins@build.gluster.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>

* protocol/server: forget the inodes which got ENOENT in lookupRaghavendra Bhat2015-08-201-22/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | If a looked up object is removed from the backend, then upon getting a revalidated lookup on that object ENOENT error is received. protocol/server xlator handles it by removing dentry upon which ENOENT is received. But the inode associated with it still remains in the inode table, and whoever does nameless lookup on the gfid of that object will be able to do it successfully despite the object being not present. For handling this issue, upon getting ENOENT on a looked up entry in revalidate lookups, protocol/server should forget the inode as well. Though removing files directly from the backend is not allowed, in case of objects corrupted due to bitrot and marked as bad by scrubber, objects are removed directly from the backend in case of replicate volumes, so that the object is healed from the good copy. For handling this, the inode of the bad object removed from the backend should be forgotten. Otherwise, the inode which knows the object it represents is bad, does not allow read/write operations happening as part of self-heal.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* core: Add inode context merge callbackVenky Shankar2015-03-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain translators may require to update the inode context of an already linked inode before unwinding the call to the client. Normally, such a case in encountered during parallel operations when a fresh inode is chosen at call (wind) time. In the callback path, one of inodes is successfully linked in the inode table, thereby the other inodes being thrown away (and the inode pointers for these calls being pointed to the linked inode). Translators which may have strict dependency on the correct value in the inode context would get stale values in inode context. This patch introduces a new callback which provides gives translators an opportunity to "patch" their respective inode contexts. Note that, as of now, this callback is only invoked during create()s unwind path. Although this might needed to be done for all dentry fops and lookup, but let that be done as an when required (bitrot stub requires this *only* for create()).

* every/where: add GF_FOP_IPC for inter-translator communicationJeff Darcy2015-03-171-0/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several features - e.g. encryption, erasure codes, or NSR - involve multiple cooperating translators which sometimes need a "private" means of communication amongst themselves. Historically we've used virtual or synthetic xattrs, but that's not very elegant and clutters up the getxattr/setxattr path which must also handle real xattr requests. This new fop should address that. The only argument is an int32_t "op" which should be recognized by the target translator. It is recommended that translators using these feature follow some convention regarding the ops that they define, to avoid conflicts. Using a hash of the target translator's type string as a base for a series of ops would probably be a good start. Any other information can be passed in both directions using xdata. The default behavior for this fop, as with any other, is to pass through to FIRST_CHILD. That makes use of this fop "transparent" to other translators that were written before it existed, but it also means that it only really works with pass-through translators. If a routing translator (such as DHT) or a fan-out translator (such as AFR) is involved, the IPC might not reach its intended destination unless those translators are modified to forward IPC fops along all paths. If an IPC gets all the way to storage/posix it is considered an error, much like an uncaught exception. We don't actually *do* anything in that case, but we do log it send back an EOPNOTSUPP error. This makes the "unrecognized opcode" condition distinguishable from the "no IPC support" condition (which would yield an RPC error instead) so clients can probe for the presence of a handler for their own favorite opcode and either use that or use old-school xattrs depending on the result.
