* gfapi : added glfs_setfsleaseid() for setting lease idSoumya Koduri2018-01-195-0/+32
| | | | | | | | | | | | A new function glfs_setfsleaseid() added in gfapi. Currently lock owner is saved in the thread context. Similarly the leaseid attribute can be saved using glfs_setfsleaseid().

* afr: add quorum checks in post-opRavishankar N2018-01-192-1/+30
| | | | | | | | | | afr relies on pending changelog xattrs to identify source and sinks and the setting of these xattrs happen in post-op. So if post-op fails, we need to unwind the write txn with a failure. Change-Id: I0f019ac03890108324ee7672883d774918b20be1 BUG: 1506140 Signed-off-by: Ravishankar N <ravishankar@redhat.com>

* upcall: Allow md-cache to specify invalidations on xattr with wildcardPoornima G2018-01-192-4/+21
| | | | | | | | | | | | | Currently, md-cache sends a list of xattrs, it is inttrested in recieving invalidations for. But, it cannot specify any wildcard in the xattr names Eg: user.* - invalidate on updating any xattr with user. prefix.

* posix: In getxattr, honor the wildcard '*'Poornima G2018-01-192-23/+43
| | | | | | | | | | | | | | | | | Currently, the posix_xattr_fill performas a sys_getxattr on all the keys requested, there are requirements where the keys could contain a wildcard, in which case sys_getxattr would return ENODATA, eg: if the xattr requested is user.* all the xattrs with prefix user. should be returned, with their values. This patch, changes posix_xattr_fill, to honor wildcard in the keys requested. Updates #297 Change-Id: I3d52da2957ac386fca3c156e26ff4cdf0b2c79a9 Signed-off-by: Poornima G <pgurusid@redhat.com>
* cluster/afr: Adding option to take full file lockkarthik-us2018-01-195-3/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In replica 3 volumes there is a possibilities of ending up in split brain scenario, when multiple clients writing data on the same file at non overlapping regions in parallel. Scenario: - Initially all the copies are good and all the clients gets the value of data readables as all good. - Client C0 performs write W1 which fails on brick B0 and succeeds on other two bricks. - C1 performs write W2 which fails on B1 and succeeds on other two bricks. - C2 performs write W3 which fails on B2 and succeeds on other two bricks. - All the 3 writes above happen in parallel and fall on different ranges so afr takes granular locks and all the writes are performed in parallel. Since each client had data-readables as good, it does not see file going into split-brain in the in_flight_split_brain check, hence performs the post-op marking the pending xattrs. Now all the bricks are being blamed by each other, ending up in split-brain. Fix: Have an option to take either full lock or range lock on files while doing data transactions, to prevent the possibility of ending up in split brains. With this change, by default the files will take full lock while doing IO. If you want to make use of the old range lock change the value of "cluster.full-lock" to "no".

* cluster/afr: Fixing the flaws in arbiter becoming source patchkarthik-us2018-01-137-180/+271
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Setting the write_subvol value to read_subvol in case of metadata transaction during pre-op (commit 19f9bcff4aada589d4321356c2670ed283f02c03) might lead to the original problem of arbiter becoming source. Scenario: 1) All bricks are up and good 2) 2 writes w1 and w2 are in progress in parallel 3) ctx->read_subvol is good for all the subvolumes 4) w1 succeeds on brick0 and fails on brick1, yet to do post-op on the disk 5) read/lookup comes on the same file and refreshes read_subvols back to all good 6) metadata transaction happens which makes ctx->write_subvol to be assigned with ctx->read_subvol which is all good 7) w2 succeeds on brick1 and fails on brick0 and this will update the brick in reverse order leading to arbiter becoming source Fix: Instead of setting the ctx->write_subvol to ctx->read_subvol in the pre-op statge, if there is a metadata transaction, check in the function __afr_set_in_flight_sb_status() if it is a data/metadata transaction. Use the value of ctx->write_subvol if it is a data transactions and ctx->read_subvol value for other transactions. With this patch we assign the value of ctx->write_subvol in the afr_transaction_perform_fop() with the on disk value, instead of assigning it in the afr_changelog_pre_op() with the in memory value.

* rpc: use export map to minimize exported symbols in libgf{rpc,xdr}.soKaleb S. KEITHLEY2018-01-124-3/+318
| | | | | | | | | | | | | | | | | | | | | | | | Without an export map (at link time) libgrpc and libgfxdr export over 150 and 450 symbols each, respectively. Many are not used by anything else. (Unclear what the unused symbols are, some may be simple sloppiness, e.g. not declaring functions static that should be. Others may be intra-library calls that can't be static but aren't part of the API, per se.) By linking with an export map the number of exported symbols is reduced to ~60 and ~250 respectively. This parallels the similar change made to libglusterfs recently and the older changes to the xlators to minimize the symbols that are visible (exported) from the .so. And I don't know, do we want to go all the way to symbol versions? For these libs? And for libglusterfs? fixes gluster/glusterfs#392 Change-Id: I9cdc3eee10e5f1408d7e7f2f29fad597c97e4003 Signed-off-by: Kaleb S. KEITHLEY <kkeithle@redhat.com>

* glusterd: fix up volume option flagsCsaba Henk2018-01-071-3/+3
| | | | | | | | | | | | | | | | | | | | | | In glusterd volfile generation code options should be ornamented with the VOLOPT_FLAG_* flags. However, some are ornamented with OPT_FLAG_* flags (which are to be used in xlator context). The impact is: the OPT_FLAG_* that occurs is OPT_FLAG_CLIENT_OPT, which has the same value as VOLOPT_FLAG_XLATOR_OPT, so what was meant is "option affects clients" and what was there means "option enables/disables xlators". Because of this semantic shift, op version might be incorrectly calculated for volumes and clients. (At this point it's a theoretical possibility. Actual occurrence might depend on connecting client & server versions; it's also possible that there exists a proof of concept scenario but it's irrealistic.) This commit eliminates the OPT_FLAG_* occurrences from glusterd code, and replaces them with the appropriate VOLOPT_FLAG_* flags.

* cluster/dht: Use percentages for space checkN Balachandran2018-01-022-5/+25
| | | | | | | | | | | | | | | | | With heterogenous bricks now being supported in DHT we could run into issues where files are not migrated even though there is sufficient space in newly added bricks which just happen to be considerably smaller than older bricks. Using percentages instead of absolute available space for space checks can mitigate that to some extent. Marking bug-1247563.t as that used to depend on the easier code to prevent a file from migrating. This will be removed once we find a way to force a file migration failure.

* libglusterfs: export minimum necessary symbolsKaleb S. KEITHLEY2018-01-022-2/+1093
| | | | | | | | | | | | | | | | | | | | | | minimize risk of symbol collisions in global namespace. see https://review.gluster.org/#/c/5697/ which Amar has resurrected. This is a strawman proposal to use an export-list to only export the necessary symbols from libglusterfs. I suppose some of this could be fixed by smarter use of static in the function definitions. It's a bit scary to see some of the names we expose. And then there are the names we use in the reserved namespace. One step short of going all the way to symbol versions fixes gluster/glusterfs#382 Change-Id: Ifb848dfc655ef735dd27c73b7729e1188eb817f1 Signed-off-by: Kaleb S. KEITHLEY <kkeithle@redhat.com>
