* glusterd: big lock - a coarse-grained locking to prevent racesKrishnan Parthasarathi2013-04-121-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are primarily three lists that are part of glusterd process, that are concurrently accessed. Namely, priv->volumes, priv->peers and volinfo->bricks_list. Big-lock approach ----------------- WHAT IS IT? Big lock is a coarse-grained lock which protects all three lists, mentioned above, from racy access. HOW DOES IT WORK? At any given point in time, glusterd's thread(s) are in execution _iff_ there is a preceding, inbound network event. Of course, the sigwaiter thread and timer thread are exceptions. A network event is an external trigger to glusterd, via the epoll thread, in the form of POLLIN and POLLERR. As long as we take the big-lock at all such entry points and yield it when we are done, we are guaranteed that all the network events, accessing the global lists, are serialised. This amounts to holding the big lock at - all the handlers of all the actors in glusterd. (POLLIN) - all the cbks in glusterd. (POLLIN) - rpc_notify (DISCONNECT event), if we access/modify one of the three lists. (POLLERR) In the case of synctask'ized volume operations, we must remember that, if we held the big lock for the entire duration of the handler, we may block other non-synctask rpc actors from executing. For eg, volume-start would block in PMAP SIGNIN, if done incorrectly. To prevent this, we need to yield the big lock, when we yield the synctask, and reacquire on waking up of the synctask.

| | | | | | | | | | | | | | | | | | | | | - enable-pump option in the pump xlator is set during a replace-brick session. This was persisted in the volinfo->dict for volume file generation. It has two 'harmful' side-effects, a) It would lead to volinfo cksum divergence among peers in cluster (for the same version no.) during a replace-brick session. b) "enable-pump" key would appear in "gluster volume info VOLNAME". This key is used internally in volume file generation code to optionally load the pump xlator in the source brick. It is _not_ an volume option.

* glusterd: log appropriate message when locking failsKrutika Dhananjay2012-12-111-11/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: When a transaction is already in progress, and the user tries to execute another glusterd operation, the second operation fails as glusterd fails to acquire lock. But to the user, a message like "Operation failed" does not give ample information about why the operation failed. FIX: Made glusterd_op_txn_begin use and initialise error string, which is needed to capture failure in the "lock" phase. Also made gd_sync_task_begin set error string appropriately when locking fails. In the process, I had to introduce error string in some glusterd_handle_* functions. And because I introduced error string in these handlers, I decided to also set them in places where these handlers could possibly fail. HOW I TESTED IT: For want of a better idea, I "commented out" the call to "glusterd_unlock", recompiled glusterd and ran two glusterd volume operations, one after the other. The second operation fails with the message "Another transaction is in progress. Please try again after sometime." as expected. The tests were performed on two volume ops : one of them synctask'ized (volume start) and the other NOT (volume create).

* glusterd: Fix to log command status at the appropriate timeKrutika Dhananjay2012-09-201-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: In the existing implementation, the success/failure of execution of a command is decided (and logged) in glusterd handler functions. Strictly speaking, the logging mechanism must take into account what course the command takes within the state machine before concluding whether it succeeded or failed. FIX: This patch attempts to fix the above issue for vol commands. The format of the log message is as follows: for failure: <command string> : FAILED : <cause of failure> for success: <command string> : SUCCESS APPROACH (in a nutshell): * The command string is packed into dict at cli and sent to glusterd. * glusterd logs the command status just before doing a "submit_reply", which is called (either directly or indirectly via a call to glusterd_op_cli_send_response) at 2 places for every vol command: i. in handler functions, and ii. in glusterd_op_txn_complete In short, the failure of a command in the handler implies the command has indeed failed. However, its success in the handler does NOT necessarily mean the command succeeded/will succeed.

There's a non-zero chance that another thread calling localtime (or ctime) will over-write the static data about to be used in another thread 2) localtime(& <64-bit-type>) or ctime(& <64-bit-type>) generally not a problem on 64-bit or little-endian 32-bit. But even though we probably have zero users on big-ending 32-bit platforms, it's still incorrect. 3) multiple nested calls passed as params. Last one wins, i.e. over- writes result of prior calls. 4) Inconsistent error handling. Most of these calls are for logging, tracing, or dumping. I submit that if an error somehow occurs in the call to localtime or ctime, the log/trace/dump still should still occur. 5) Appliances should all have their clocks set to UTC, and all log entries, traces, and dumps should use GMT. 6) fix strtok(), change to strtok_r() Other things this patch fixes/changes (that aren't bugs per se): 1) Change "%Y-%m-%d %H:%M:%S" and similar to their equivalent shorthand, e.g. "%F %T" 2) change sizeof(timestr) to sizeof timestr. sizeof is an operator, not a function. You don't use i +(32), why use sizeof(<var>). (And yes, you do use parens with sizeof(<type>).) 3) change 'char timestr[256]' to 'char timestr[32]' where appropriate. Per-thread stack is limited. Time strings are never longer than ~20 characters, so why waste 220+ bytes on the stack? Things this patch doesn't fix: 1) hodgepodge of %Y-%m-%d %H:%M:%S versus %Y/%m/%d-%H%M%S and other variations. It's not clear to me whether this ever matters, not to mention 3rd party log filtering tools may already rely on a particular format. Still it would be nice to have a single manifest constant and have every call to localtime/strftime consistently use the same format.

This is to avoid directory creation as part 'force'ful starting of volume and leave the responsibility with the user, who understands the 'availability' of the export directory (brick) better.

| | | | | | | | | | | | | | | | | | - commit force subcommand of replace-brick (rb) should be allowed even if source brick is (irrecoverably) offline. - modified rb_timer to be active only for start subcommand. This is important since, the rb timer event relies on src_brick and dst_brick objects to be 'alive' when it 'happens'. In the case of abort/commit/commit force it is very likely that src_brick and/or dst_brick objects could have been destroyed.

| | | | | | | | | | | | | | | | | | currently this is implemented as a command line option, and not as an easier translator option. this is because as of now, before even the volume files are parsed, we would need memory accounting enabled. there is scope for improving this behavior, but for now, this approach solves the problem. Also, this feature's major consumers are the testers who are looking for leaks, hence option is hidden from usage output.

* glusterd: auth allow enhancementsRajesh Amaravathi2012-02-201-11/+46

E.g: volume vol in a cluster of two peers: /mnt/brick1 in 192.168.1.4 /mnt/brick2 in 192.168.1.5 option auth.allow 192.168.1.6 (allow connection requests only from 192.168.1.6) This will disrupt the nfs servers on 192.168.1.{4,5}. brick server processes reject connection requests from both nfs servers (on 4,5), because the peer addresses are not in the auth.allow list. Same holds true for local mounts (on peer machines), self-heal daemon, and other operations which perform a glusterfs mount on one of the peers. * SOLUTION: Login-based authentication (username/password pairs, henceforth referred to as "keys") for gluster services and operations. These *per-volume* keys can be used to by-pass the addr-based authentication, provided none of the peers' addresses are put in the auth.reject list, to enable gluster services like gNfs, self-heal daemon and internal operations on volumes when auth.allow option is exercised. * IMPLEMENTATION: 1. Glusterd generates keys for each volume and stores it in memory as well as in respective volfiles. A new TRUSTED-FUSE volfile is generated which is fuse volfile + keys in protocol/client, and is named trusted-<volname>-fuse.vol. This is used by all local mounts. ANY local mount (on any peer) is granted the trusted-fuse volfile instead of fuse volfile via getspec. non-local mounts are NOT granted the trusted fuse volfile. 2. The keys generated for the volume is written to each server volfile telling servers to allow users with these keys. 3. NFS, self-heal daemon and replace-brick volfiles are updated with the volume's authentication keys. 4. The keys are NOT written to fuse volfiles for obvious reasons. 5. The ownership of volfiles and logfiles is restricted to root users. 6. Merging two identical definitions of peer_info_t in auth/addr and rpc-lib, throwing away the one in auth/addr. 7. Code cleanup in numerous places as appropriate. * IMPORTANT NOTES: 1. One SHOULD NOT put any of the peer addresses in the auth.reject list if one wants any of the glusterd services and features such as gNfs, self-heal, rebalance, geo-rep and quota. 2. If one wants to use username/password based authentication to volumes, one shall append to the server, nfs and shd volfiles, the keys one wants to use for authentication, *while_retaining those_generated_by_glusterd*. See doc/authentication.txt file for details.
