* core: use readdir(3) with glibc, and associated cleanupKaleb S. KEITHLEY2016-07-181-18/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with glibc-2.23 (i.e. what's in Fedora 25), readdir_r(3) is marked as deprecated. Specifically the function decl in <dirent.h> has the deprecated attribute, and now warnings are thrown during the compile on Fedora 25 builds. The readdir(_r)(3) man page (on Fedora 25 at least) and World+Dog say that glibc's readdir(3) is, and always has been, MT-SAFE as long as only one thread is accessing the directory object returned by opendir(). World+Dog also says there is a potential buffer overflow in readdir_r(). World+Dog suggests that it is preferable to simply use readdir(). There's an implication that eventually readdir_r(3) will be removed from glibc. POSIX has, apparently deprecated it in the standard, or even removed it entirely. Over and above that, our source near the various uses of readdir(_r)(3) has a few unsafe uses of strcpy()+strcat(). (AFAIK nobody has looked at the readdir(3) implemenation in *BSD to see if the same is true on those platforms, and we can't be sure of MacOS even though we know it's based on *BSD.)

* cli/glusterd: add/remove brick fixes for arbiter volumesRavishankar N2016-05-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1.Provide a command to convert replica 2 volumes to arbiter volumes. Existing self-heal logic will automatically heal the file hierarchy into the arbiter brick, the progress of which can be monitored using the heal info command. Syntax: gluster volume add-brick <VOLNAME> replica 3 arbiter 1 <HOST:arbiter-brick-path> 2. Add checks when removing bricks from arbiter volumes: - When converting from arbiter to replica 2 volume, allow only arbiter brick to be removed. - When converting from arbiter to plain distribute volume, allow only if arbiter is one of the bricks that is removed. 3. Some clean-up: - Use GD_MSG_DICT_GET_SUCCESS instead of GD_MSG_DICT_GET_FAILED to log messages that are not failures. - Remove unused variable `brick_list` - Move 'brickinfo->group' related functions to glusted-utils.

* glusterd: copy real_path from older brickinfo during brick importAtin Mukherjee2016-05-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | In glusterd_import_new_brick () new_brickinfo->real_path will not be populated for the first time and hence if the underlying file system is bad for the same brick, import will fail resulting in inconsistent configuration data. Fix is to populate real_path from old brickinfo object. Also there were many cases where we were unnecessarily calling realpath() and that may cause in failure. For eg - if a remove brick is executed with a brick whoose underlying file system has crashed, remove-brick fails since realpath() call fails. We'd need to call realpath() here as the value is of no use.Hence passing construct_realpath as _gf_false in glusterd_volume_brickinfo_get_by_brick () is a must in such cases.

In production environment generally administrator makes firewall configuration for a range of ports for a volume.

| | | | | | | | | | | | | | | | | | | | glusterd_brickinfo_new_from_brick () is called from multiple places and one of them is glusterd_brick_rpc_notify where its very well possible that an underlying brick's file system has crashed and a disconnect event has been received. In this case glusterd tries to build the brickinfo from the brickid in the RPC request, however the same fails as glusterd_brickinfo_new_from_brick () fails from realpath. Fix is to skip populating real_path if its a disconnect event.

| | | | | | | | | | | | | | | | | | | | | | Commit a60c39d introduced a new field called real_path in brickinfo to hold the realpath() conversion. However at restore path for all snapshots and snapshot restored volumes the brickpath gets recreated post restoration of bricks which means the realpath () call will fail here for all the snapshots and cloned volumes. Fix is to store the realpath for snapshots and clones post recreating the brick mounts. For normal volume it would be done during retrieving the brick details from the store.

| | | | | | | | | | | | | | | | | | | | | | | | | | There is no point of using the same port through the entire volume life cycle for a particular bricks process since there is no guarantee that the same port would be free and no other application wouldn't consume it in between the glusterd/volume restart. We hit a race where on glusterd restart the daemon services start followed by brick processes and the time brick process tries to bind with the port which was allocated by glusterd before a restart is been already consumed by some other client like NFS/SHD/... Note : This is a short term solution as here we reduce the race window but don't eliminate it completely. As a long term solution the port allocation has to be done by glusterfsd and the same should be communicated back to glusterd for book keeping Change-Id: Ibbd1e7ca87e51a7cd9cf216b1fe58ef7783aef24 BUG: 1322805 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-on: http://review.gluster.org/13865 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>

The above flow breaks the usecases where a gluster image is built following a template could be Dockerfile, Vagrantfile or any kind of virtualization environment. This means bringing instances of this image would have same UUIDs for the node resulting in peer probe failure. Solution is to lazily initialize the services on demand.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* glusterd: CLI commands to create and manage tiered volumes.Dan Lambright2015-03-191-0/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A tiered volume is a normal volume with some number of new bricks representing "hot" storage. The "hot" bricks can be attached or detached dynamically to a normal volume. When this happens, a new graph is constructed. The root of the new graph is an instance of the tier translator. One subvolume of the tier translator leads to the old volume, and another leads to the new hot bricks. attach-tier <VOLNAME> [<replica> <COUNT>] <NEW-BRICK> ... [force] volume detach-tier <VOLNAME> [replica <COUNT>] <BRICK> ... <start|stop|status|commit|force> gluster volume rebalance <volume> tier start gluster volume rebalance <volume> tier stop gluster volume rebalance <volume> tier status The "tier start" CLI command starts a server side daemon. The daemon initiates file level migration based on caching policies. The daemon's status can be monitored and stopped. Note development on the "tier status" command is incomplete. It will be added in a subsequent patch. When the "hot" storage is detached, the tier translator is removed from the graph and the tiered volume reverts to its original state as described in the volume's info file.

* glusterd: Protect the peer list and peerinfos with RCU.Kaushal M2015-03-161-2/+5

Design patterns described in the Paul McKenney's RCU dissertation [1] (sections 5 and 6) have been used to convert existing non-RCU protected code to RCU protected code. Currently, we are only targetting guaranteeing the existence of the peerinfo objects, ie., we are only looking to protect deletes, not all updaters. We chose this, as protecting all updates is a much more complex task. The steps used to accomplish this are, 1. Remove all long lived direct references to peerinfo objects (apart from the peerinfo list). This includes references in glusterd_peerctx_t (RPC), glusterd_friend_sm_event_t (friend state machine) and others. This way no one has a reference to deleted peerinfo object. 2. Replace the direct references with indirect references, ie., use peer uuid and peer hostname as indirect references to the peerinfo object. Any reader or updater now uses the indirect references to get to the actual peerinfo object, using glusterd_peerinfo_find. Cases where a peerinfo cannot be found are handled gracefully. 3. The readers get and use the peerinfo object only within a RCU read critical section. This prevents the object from being deleted/freed when in actual use. 4. The deletion of a peerinfo object is done in a ordered manner (glusterd_peerinfo_destroy). The object is first removed from the peerinfo list using an atomic list remove, but the list head is not reset to allow existing list readers to complete correctly. We wait for readers to complete, before resetting the list head. This removes the object from the list completely. After this no new readers can get a reference to the object, and it can be freed. This change was developed on the git branch at [2].
