* dht: fix rename raceJeff Darcy2014-07-172-3/+10
| | | | | | | | | | | | | | | | | | | | | | | If two clients try to rename the same file at the same time, we sometimes end up with *no file at all* in either the old or new location. That's kind of bad. The culprit seems to be some overly aggressive cleanup code. AFAICT, based on today's study of the code, the intent of the changed section is to remove any linkfile we might have created before the actual rename. However, what we're removing might not be our extra link. If we're racing with another client that's also doing a rename, it might be the only remaining link to the user's data. The solution, which is good enough to pass this test but almost certainly still not complete, is to be more selective about when we do this unlink. Now, we only do it if we know that, at some point, we did in fact create the link without error (notably ENOENT on the source or EEXIST on the destination) ourselves.

* make snapview-server more compatible with NFS serverRaghavendra Bhat2014-07-164-78/+228
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * There was no handle based API for listxattr. With this change, glfs_h_getxattrs also handles the listxattr functionality by checking whether the name is NULL or not (like posix). But all the gfapi functions for listxattr (glfs_h_getxattrs AND glfs_listxattr AND glfs_flistxattr) returns the names of the xattrs in a buffer provided by the caller. But snapview-server has to return the list of xattrs in a dict itself (similar to posix xlator). But the buffer just contains the names of the xattrs. So for each xattr, a zero byte value is set (i.e. "") into the dict and sent back. Translators which do xattr caching (as of now md-cache which caches selinux and acl related xattrs) should not cache those xattrs whose value is a zero byte data (""). So made changes in md-cache to ignore zero byte values. * NFS server was not linking the inodes to inode table in readdirp. This was leading to applications getting errors. The below set of operations would lead to applications getting error 1) ls -l in one of the snaopshots (snapview-server would generate gfids for each entry on the fly and link the inodes associated with those entries) 2) NFS server upon getting readdirp reply would not link the inodes of the entries. But it used to generate filehandles for each entry and associate the gfid of that entry with the filehandle and send it as part of the reply to nfs client. 3) NFS client would send the filehandle of one of those entries when some activity is done on it. 4) NFS server would not be able to find the inode for the gfid present in the filehandle (as the inode was not linked) and would go for hard resolution by sending a lookup on the gfid by creating a new inode. 5) snapview-client will not able to identify whether the inode is a real inode existing in the main volume or a virtual inode existing in the snapshots as there would not be any inode context. 6) Since the gfid upon which lookup is sent is a virtual gfid which is not present in the disk, lookup would fail and the application would get an error. To handle above situation, now nfs server also does inode linking in readdirp.

This patch mainly does two things, 1. Extend the peerinfo object to store a list of addresses instead of a single hostname as it does now. This also includes changes to make the peer update behaviour of 'peer probe' to add to the list. 2. Improve glusterd_friend_find_by_hostname() to perform better matching of hostnames. glusterd_friend_find_by_hostname() now does and initial quick string compare against all the peer addresses known to glusterd, after which it tries a more thorough search using address resolution and matching the struc sockaddr's. The above two changes together improve the peer identification situation in glusterd a lot.

* features/gfid-access: error handling for entry creationVenky Shankar2014-07-141-1/+7
| | | | | | | | | | | | | | | | | | | | | | | Proceed with setattr() only on a successfull entry creation. Winding a setattr() using a freshlyOC initiated inode would most likely fail in one translator or the other (e.g. DHT expecting the layout information to be set in the inode context), which is the case if the inode was not looked up. Therefore, gfid-access handles failure entry creations and passes the _correct_ errno back to the client instead of continuing with setattr() call and probably returning back incorrect errno. Also, filling up inode->gfid is required as the new inode is not looked up and ->gfid would be certainely required for inode operations.

* dht: support heterogeneous brick sizesJeff Darcy2014-07-125-31/+153
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calculation of layouts now considers the size of each brick, so that smaller bricks don't get an "unfair" share of allocations and start returning ENOSPC while the larger bricks still have plenty of space. The observation has been made that some clients might get ENOTCONN when trying to fetch disk-size information, and end up calculating layouts differently. The following meta-observations can be made. (1) This scenario is extremely unlikely in configurations with AFR. (2) The most likely consequence of this scenario is that some files will be placed sub-optimally by the client with the obsolete (non-weighted) layout. They'll still be found anyway, so this isn't a show stopper. (3) Without this patch it's *guaranteed* that some files will be placed sub-optimally, because any layout that fails to account for brick sizes is sub-optimal. (4) We shouldn't be doing fix-layout from two nodes simultaneously anyway. That's inefficient at best. Any instances of such behavior are separate bugs, which should be fixed separately. (5) In the most extreme edge case, two nodes doing weighted and non-weighted layout fixes could race and end up creating an internally inconsistent layout. This condition is still transient; it will be detected and repaired automatically the next time anyone fetches the layout. (If it's not that's also a preexisting bug that can show up in other contexts.) In conclusion, it's not the purpose of this patch to fix bugs elsewhere in DHT. Its purpose is to make life incrementally better for users who add new hardware with larger disks etc. than the older equipment. It's only one part of an ongoing process to improve layout management and repair, all the way up to support for multiple hash rings or tiering.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two new options have been added to the 'create' command of the cli interface: disperse [<count>] redundancy <count> Both are optional. A dispersed volume is created by specifying, at least, one of them. If 'disperse' is missing or it's present but '<count>' does not, the number of bricks enumerated in the command line is taken as the disperse count. If 'redundancy' is missing, the lowest optimal value is assumed. A configuration is considered optimal (for most workloads) when the disperse count - redundancy count is a power of 2. If the resulting redundancy is 1, the volume is created normally, but if it's greater than 1, a warning is shown to the user and he/she must answer yes/no to continue volume creation. If there isn't any optimal value for the given number of bricks, a warning is also shown and, if the user accepts, a redundancy of 1 is used. If 'redundancy' is specified and the resulting volume is not optimal, another warning is shown to the user. A distributed-disperse volume can be created using a number of bricks multiple of the disperse count.

* features/changelog: prevent deadlock on thread cancellationVenky Shankar2014-07-111-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | helper threads (fsync, rollover) wake up periodically and perform their respective operation under a lock (crt->lock). These threads are also subjected to cancellation under some circumstance such as disabling changelog. This is inherently dangerous when funtions which are cancellation points for pthread_cancel(3) are used in the locked region. Consider this pthread_mutex_lock(&mutex); { /* ... */ ret = fsync (fd); <-- cancellation point /* ... */ } pthread_mutex_unlock(&mutex); A pthread_cancel(3) by another thread just before fsync(3) but after pthread_mutex_lock(3) would result in the thread getting cancelled when fsync(3) is invoked, thereby never unlocking the mutex. Moreover, in case of changelog translator, the locked region (under crt->lock in changelog-rt.c) is also the code path for fop changelog updation. Therefore, unlocking the mutex in thread cleanup handler (pthread_cleanup_pop(3)) might prematurely release the mutex during fop updation path. This patch fixes such problems existing in fsync and rollover threads. Fix is to enter the locked region with cancellation disabled and enable it after mutex unlock. Also, test for a cancellation request early on in case none of the functions are cancellation points.

* socket/glusterd/client: enable SSL for managementJeff Darcy2014-07-102-5/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The feature is controlled by presence of the following file: /var/lib/glusterd/secure-access See the comment near the definition of SECURE_ACCESS_FILE in glusterfs.h for the rationale. With this enabled, the following rules apply to connections: UNIX-domain sockets never have SSL. Management-port sockets (both connecting and accepting, in daemons and CLI) have SSL based on presence of the file. Other IP sockets have SSL based on the existing client.ssl and server.ssl volume options. Transport multi-threading is explicitly turned off in glusterd (it would otherwise be turned on when SSL is) due to multi-threading issues. Tests have been elided to avoid risk of leaving a file which will cause all subsequent tests to run with management SSL still enabled. IMPLEMENTATION NOTE The implementation is a bit messy, and consists of two stages. First we decide whether to set the relevant fields in our context structure, based on presence of the sentinel file OR a command-line override. Later we decide whether a particular connection should actually use SSL, based on the context flags plus what kind of connection we're making[1] and what kind of daemon we're in[2]. [1] inbound, outbound to glusterd port, other outbound [2] glusterd, glusterfsd, other TESTING NOTE Instead of just running one special test for this feature, the ideal would be to run all tests with management SSL enabled. However, it would be inappropriate or premature to set up an optional feature in the patch itself. Therefore, the method of choice is to submit a separate patch on top, which modifies "cleanup" in include.rc to recreate the secure-access file and associated SSL certificate/key files before each test.

This thread does not have the correct *THIS xlator set. *THIS points to the global (base) xlator structure, but GF_CALLOC() requires it to be the NFS-xlator so that assertions can get validated correctly. This is solved by passing the NFS-xlator to the pthread function, and setting the *THIS pointer explicitly in the new thread. It seems that on occasion (needs further investigation) MOUNT over UDP does not unregister itself. There can also be issues when the kernel NLM implementation has been registered at portmap/rpcbind, so adding some unregister procedures in the cleanup of the test-cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When more than one aux-mounts are performing rmdir .gfid/<pargfid>/dir simultaneously, then sometimes a hang is observed. In gfid-access xlator When virtual parent/inode are replaced with real parent/inode in loc, virtual pargfid/gfid are not replaced with real pargfid/gfid respectively. Afr is using parent_loc->gfids to order the entry locks. But parent_loc->gfid contains random/virtual gfid generated by gfid-access xlator. Entrylk in client xlator is using loc->inod->gfid for sending entrylk which has 'real' gfid. Because the ordering is happening based on random gfids, One mount orders the locks as (L1, L2) where as the other orders them as (L2, L1) leading to a dead-lock thus a hang.

* feature/changelog: Fix for missing changelogs at backend.Kotresh H R2014-06-302-4/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: A few changelog files are missing at the backend during snapshot with changelog enabled. Cause: Race between actual rollover and explicit rollover. Changelog rollover can happen either due to actual or the explict rollover due to snapshot. Actual rollover is controlled by tuneable called rollover-time. The minimum granularity for rollover-time is 1 second Explicit rollover is asynchronous in nature and happens during snapshot. Basically, rollover renames the current CHANGELOG file to CHANGELOG.TIMESTAMP after rollover-time. Let's assume, at time 't1', actual and explicit rollover raced against each other and actual rollover won the race renaming the CHANGELOG file to CHANGELOG.t1 and opens a new CHANGELOG file. An immediate explicit rollover at time 't1' happened with in the same second to rename CHANGELOG file to CHANGELOG.t1 resulting in purging the earlier CHANGELOG.t1 file created by actual rollover. Solution: Adding a delay of 1 sec guarantees unique CHANGELOG.TIMESTAMP during explicit rollover. Thanks Venky, for the all the help in root causing the issue.

| | | | | | | | | | | | | | | | | | Write operations on directories with quota enabled used to fail with EINVAL on stripe volumes. This was due to assert failure in stripe_lookup(), meant to ensure loc->path is not NULL. However, in nameless lookup (in this particular case triggered by quotad, which has stripe xlator in its graph), loc->path can be legitimately NULL. The fix involves removing this check in stripe_lookup().

* gNFS: Fix multi-homed m/c issue in NFS subdir authSantosh Kumar Pradhan2014-06-252-90/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | NFS subdir authentication doesn't correctly handle multi-homed (host with multiple NIC having multiple IP addr) OR multi-protocol (IPv4 and IPv6) network addresses. When user/admin sets HOSTNAME in gluster CLI for NFS subdir auth, mnt3_verify_auth() routine does not iterate over all the resolved n/w addrs returned by getaddrinfo() n/w API. Instead, it just tests with the one returned first. 1. Iterate over all the n/w addrs (linked list) returned by getaddrinfo(). 2. Move the n/w mask calculation part to mnt3_export_fill_hostspec() instead of doing it in mnt3_verify_auth() i.e. calculating for each mount request. It does not change for MOUNT req. 3. Integrate "subnet support code rpc-auth.addr.<volname>.allow" and "NFS subdir auth code" to remove code duplication.
