* 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.

* cli/glusterd: Added support for dispersed volumesXavier Hernandez2014-07-118-9/+168
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 is to avoid indefinite recursion of the following kind, that could lead to a stack overflow: rpc_clnt_start_ping() -> rpc_clnt_ping() -> rpc_clnt_submit() -> rpc_clnt_start_ping() -> rpc_clnt_ping() -> rpc_clnt_submit() ... and so on, since it is possible that before rpc_clnt_start_ping() is called a second time by the thread executing this codepath, the response to previous ping request could ALWAYS come by and cause epoll thread to reset conn->ping_started to 0. This patch also fixes the issue of excessive ping traffic, which was due to the client sending one ping rpc for every fop in the worst case. Also removed dead code in glusterd.

* nfs: prevent assertion error with MOUNT over UDPNiels de Vos2014-07-072-1/+10
| | | | | | | | | | | | | | | | | | | | | | | The MOUNT service over UDP runs in a separate thread. 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. Fix: Replace virtual pargfid/gfid with real pargfid/gfid when virtual-inodes are replaced with real-inodes in loc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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().

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* cluster/dht: handle ESTALE appropriately in rmdir codepath.Raghavendra G2014-06-231-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Till we separated the scenario of a file/directory not existing from parent not existing [1], we used to include a subvolume in the layout of a directory even if it is not present on that subvolume. This was done to allow a lookup racing with mkdir to create correct layout. However, there are other scenarios as well where a directory is not present. One such situation is trying to create a directory after an add-brick. Since there is no guarantee that all the ancestors are created after an add-brick (and hence directory cannot be created), the newly added brick should not be part of the layout. However, we used to consider newly added brick as part of layout (even before we do fix-layout of all the ancestors) and this was the root cause of [2]. With [1], this issue got fixed and hence [2] got fixed too. However, [1] is not complete in the sense we didn't modify rmdir codepath appropriately. This patch fixes that gap.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: io-stats tries to init log-buf-size as uint32. All gf_string2u*** functions which get the unsigned values from string don't want the string to contain '-'. So the GF_OPTION_INIT with '-0' as value fails init in io-stats, but by that time 'ret' is already reset to 0. Io-stats ends up returning 0 even when init failed. Because of this caller of init thinks initialization is successful when it is not. iostat_xlator->private is still NULL. Because of this when a fop tries to access members of io-stat-private structure, it crashes. Fix: I initially thought may be we should fix all gf_string2u*** functions to accept '-0'. But all these functions are used only for setting volume options. If we accept '-0', gluster volume info shows output as follows: diagnostics.brick-log-buf-size: -0 This seemed ugly, so I felt it is better to disallow '-0' as valid input for numbers. Also fixed return value in cases of failures in io-stats.
