* protocol/server: do not do root-squashing for trusted clientsRaghavendra Bhat2014-02-1017-9/+406
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * As of now clients mounting within the storage pool using that machine's ip/hostname are trusted clients (i.e clients local to the glusterd). * Be careful when the request itself comes in as nfsnobody (ex: posix tests). So move the squashing part to protocol/server when it creates a new frame for the request, instead of auth part of rpc layer. * For nfs servers do root-squashing without checking if it is trusted client, as all the nfs servers would be running within the storage pool, hence will be trusted clients for the bricks. * Provide one more option for mounting which actually says root-squash should/should not happen. This value is given priority only for the trusted clients. For non trusted clients, the volume option takes the priority. But for trusted clients if root-squash should not happen, then they have to be mounted with root-squash=no option. (This is done because by default blocking root-squashing for the trusted clients will cause problems for smb and UFO clients for which the requests have to be squashed if the option is enabled). * For geo-replication and defrag clients do not do root-squashing. * Introduce a new option in open-behind for doing read after successful open.

* glusterd: Volume locks and transaction specific opinfosAvra Sengupta2014-02-1026-250/+2329
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch we are replacing the existing cluster-wide lock taken on glusterds across the cluster, with volume locks which are also taken on glusterds across the cluster, but are volume specific. So with the volume locks we are able to perform more than one gluster operation at the same time, as long as the operations are being performed on different volumes. We maintain a global list of volume-locks (using a dict for a list) where the key is the volume name, and which saves the uuid of the originator glusterd. These locks are held and released per volume transaction. In order to acheive multiple gluster operations occuring at the same time, we also separate opinfos in the op-state-machine, as a part of this patch. To do so, we generate a unique transaction-id (uuid) per gluster transaction. An opinfo is then associated with this transaction id, which is used throughout the transaction. We maintain a run-time global list(using a dict) of transaction-ids, and their respective opinfos to achieve this.

* cluster/dht: If hashed_subvol is NULL, do not failSusant Palai2014-02-081-3/+3
| | | | | | | | | | | | | | | | | | | | | Problem: With the current implementation we are allowing unlink of a file if hashed subvol is down and cached subvol is up. For the above op to work we should have the info of hashed_subvol. But incase we do remount of the volume we will have a zeroed layout for the disconnected subvol(start=0, stop=0, err=ENOTCONN) which will result into hashed_subvol being NULL and failing unlink op. Solution: Dont fail if hashed_subvol is NULL. Check cached subvol and unlink in cached subvol. The linkto file in the hashed subvol can be remove later.

* Problem : getfattr fails and mount point becomes inaccessible while Atin Mukherjee2014-02-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | fetching glusterfs.ancestry.path key value for a gfid from aux-gfid-mount based mount point. Analysis : The caller of posix_make_ancestryfromgfid() function i.e. posix_get_ancestry_non_directory() is sending an incorrect type value as an argument leading to a crash in posix_make_ancestral_node() (head dirent pointer is NULL and an attempt to dereference causes seg fault). For a non directory operation this piece of code should not have been executed but due to incorrect type value this happened. Solution : In posix_make_ancestryfromgfid() call type is passed as logical or of type and POSIX_ANCESTRY_PATH instead of logical or of POSIX_ANCESTRY_PATH and POSX_ANCESTRY_DENTRY.

* cluster/dht: Fix layout sortingPoornima G2014-02-031-7/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The layout was not being sorted in the ascending order leading to the wrong detection of holes/overlaps. From looking at the previous git commits it appears that the initial version itself had the err comparison code. Deductions from the current dht_layout_sort(): 1. The zero'ed out layouts should be in the from of list, if needed 2. The layout should be sorted in the ascending order of layout error value. 3. The layout should be sorted in the ascending order of the layout 'start'. But In some cases, with the err comparison code its not sorted in the ascending order. Example: If the input is as below for dht_layout_sort(), the sorting doesn't happen in ascending order. Input: 0-1 err:0 2-3 err:0 6-7 err:0 0-0 err:20 4-5 err:0 With the current sort, Output: 4-5 err:0 0-0 err:0 0-1 err:0 2-3 err:0 6-7 err:0 Expected: 0-0 err:20 0-1 err:0 2-3 err:0 4-5 err:0 6-7 err:0 Looking at dht_layout_anomalies() it appears that, it doesn't require the layout to be sorted based on error value. The other solution was to replace line 468 with: if ((layout->list[i].err || layout->list[j].err) && (layout->list[i].start > layout->list[j].start)) Since dht_layout_anomalies() didn't expect the layout to be sorted based on the error, removed the err comparison.

* glusterd: Fix race in pid file updateRavishankar N2014-02-032-32/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch only removes lines of code. For personal gratification, giving a detailed explanation of what the problem was. When glusterd spawns the local brick process, say when a reboot of the node occurs,the glusterd_brick_start() and subsequently the glusterd_volume_start_glusterfs() function gets called twice; from glusterd_spawn_daemons() and glusterd_do_volume_quorum_action() respectively. This causes a race, best described by a pseudo-code of current behaviour. glusterd_volume_start_glusterfs() { if(!brick process running) { step-a) reap pid file( i.e. unlink it) step-b) fork a brick process which creates and locks pid file and binds the process to a socket. } } Time Event ---- ----- T1 Call-1 arrives, completes step-a, starts step-b T2 Call-2 arrives, enters step-a as Call-1's forked child is not yet running. T3 Call-1's forked child is alive, creates pidfile and locks it,binds its address to a socket. T4 Call-2 performs step-a; i.e.unlinks the pid file created by Call-1 !! (files can still be stil be unlinked despite a lockf on it) T5 Call-2 does step-b, and the forked child process creates a *new* pid file with it's pid and locks this file. T6 But Call-2's brick process is not able to bind to socket as it is already in use (courtesy T3) and hence exits (so no locks anymore on the pidfile). Result: - Pid file now contains PID of an extinct brick process. - `gluster volume status` shows this PID value. It also notices that there is no lock held on pid file by the currently running brick process (created by Call-1) and hence shows N/A for the online status. Also, as a result of events at T4, "ls -l /proc/<brick process PID>/fd/pidfile" shows up as deleted. Fix: 1.Do not unlink pid file. i.e. avoid step-a. Now at T5,Call-2's brick process cannot obtain lock on pid file (Call-1's process still holds it) and exits. 2. Unrelated, but remove lock-unlock sequence in glusterfs_pidfile_setup() which does not seem to be doing anything useful.

* build: GFAPI_VERSION should be 6.0.0 not 0.0.6Harshavardhana2014-02-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | -------------------------------------> "In essence, every time you make a change to the library and release it, the C:R:A should change. A new library should start with 0:0:0. Each time you change the public interface (i.e., your installed header files), you should increment the CURRENT number." So the version which was 3 became 5 when discard API was added and became 6 when zerofill was added. As per the above description, API addition will result in a change to the installed header (glfs.h) and hence warrants a change in CURRENT number ? Should you have changed the version to 6.0.0 instead of 0.0.6 ? <------------------------------------ Thanks Bharata B Rao <bharata.rao@gmail.com> for pointing this out Change-Id: I0aa980a6713fbd28922a94c5debb170a89aa3512 BUG: 862082 Signed-off-by: Harshavardhana <harsha@harshavardhana.net> Reviewed-on: http://review.gluster.org/6790 Reviewed-by: Niels de Vos <ndevos@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Bharata B Rao <bharata.rao@gmail.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
