* extras/hooks: Do not blindly remove volume share from smb.confAnoop C S2018-05-073-9/+12
| | | | | | | | | | | | | | | | | When Gluster volumes are shared via Samba, any extra smb.conf parameter setting done by administrator to those shares are lost during restart of the volume. Instead of removing the whole share completely from smb.conf(via hook scripts during volume stop) it is better to make it temporarily unavailable to end-users till the volume is started again. Therefore we make use of a smb.conf parameter named 'available'[1] to achieve the above intend.

* gfapi: acutally avoid recall callback when closedv4.2devThomas Hindoe Paaboel Andersen2018-05-061-1/+2
| | | | | | | | | | | | Due to missing curly braces we end up calling the callback function even when state is GLFD_CLOSE. This patch adds the curly braces so both the log and actual callback is skipped.

* fuse: add support for kernel writeback cacheCsaba Henk2018-05-0410-4/+170
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Added kernel-writeback-cache command line and xlator option for requesting utilisation of the writeback cache of the kernel in FUSE_INIT (see [1]). - Added attr-times-granularity command line and xlator option via which granularity of the {a,m,c}time in stat (attr) data that we support can be indicated to kernel. This is a means to avoid divergence of the attr times between kernel and userspace that could occur with writeback-cache, while still maintaining maximum time precision the FUSE server is capable of (see [2]). - Handling FATTR_CTIME flag in FUSE_SETATTR that indicates presence of ctime in setattr payload. Currently we cannot associate arbitrary ctimes to files on backend, so we just touch them to update their ctimes to current time. Having ctimes in setattr payload is also a side effect of writeback cache (see [3] and [4]).

TODO: RECALL LEASE for each glfd (for future reference) (may be needed fo Samba as they do not deal with object handles. In case of RECALL_LEASE, we could associate separate cbk function for each glfd either by - extending pub_glfs_lease to accept new args (recall_cbk_fn, cookie) - or by defining new API "glfs_register_recall_cbk_fn (glfd, recall_cbk_fn, cookie) . In such cases, flag it and instead of calling below upcall functions, define a new one to go through the glfd list and invoke each of theirs recall_cbk_fn.

* features/bitrot: print the path of the corrupted objectsRaghavendra Bhat2018-05-047-12/+292
| | | | | | | | | | | | | | | | | | | | | | | | | Currently "gluster volume bitrot <volume name> scrub status" gives the list of the corrupted objects (files as of now). But only the gfids of those corrupted objects are seen and one has to do getfattr, find etc operations to get the actual path of those objects for removal etc. This change makes an attempt to print the path of those files as much as possible. * Try to get the path using the on disk gfid2path xattr. * If the above operation fails, then go for in memory path (provided that the object has its dentry properly created and linked in the inode table of the brick where the corrupted object is present) So the gfid to path resolution is a soft resolution, i.e. based on the inode and dentry cache in the brick's memory. If the path cannot be obtained via inode table also, then only gfid is printed.

* server/resolver: don't trust inode-table for RESOLVE_NOTRaghavendra G2018-04-301-4/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There have been known races between fops which add a dentry (like lookup, create, mknod etc) and fops that remove a dentry (like rename, unlink, rmdir etc) due to which stale dentries are left out in inode table even though the dentry doesn't exist on backend. For eg., consider a lookup (parent/bname) and unlink (parent/bname) racing in the following order: * lookup hits storage/posix and finds that dentry exists * unlink removes the dentry on storage/posix * unlink reaches protocol/server where the dentry (parent/bname) is unlinked from the inode * lookup reaches protocol/server and creates a dentry (parent/bname) on the inode Now we've a stale dentry (parent/bname) associated with the inode in itable. This situation is bad for fops like link, create etc which invoke resolver with type RESOLVE_NOT. These fops fail with EEXIST even though there is no such dentry on backend fs. This issue can be solved in two ways: * Enable "dentry fop serializer" xlator [1]. # gluster volume set features.sdfs on * Make sure resolver does a lookup on backend when it finds a dentry in itable and validates the state of itable. - If a dentry is not found, unlink those stale dentries from itable and continue with fop - If dentry is found, fail the fop with EEXIST This patch implements second solution as sdfs is not enabled by default in brick xlator stack. Once sdfs is enabled by default, this patch can be reverted.

* cluster/afr: Keep child-up until ping-eventPranith Kumar K2018-04-253-25/+40
| | | | | | | | | | | | | | | | | | | | | Problem: If we have 2 bricks, brick-A and brick-B with brick-A within halo-max-latency and brick-B more than halo-max-latency. If we set both halo-min, halo-max replicas as '1'. In this case, brick-A comes online and then ping-latency will be updated for it. When brick-B comes online, we have 2 up-bricks, so the code tries to find the brick with worst latency to mark it down. Since Brick-B just came online it always had '0' latency so brick-B used to be marked offline and Brick-B would eventually be the one to be online even when brick-A is more suited. Fix: Consider latency of just-up child as HALO_MAX_LATENCY so that worst-child until ping-latency is found as the just-up brick. Also keep ping-latency as -1 until child-up during initialization.

This expects TLS allow rules to be setup correctly rather than the default *. This option is not settable, as a result this cannot be enabled for volumes using the CLI. This is used with the shared storage volume, to restrict access to the same in non-SSL/TLS environments to the gluster peers only. Tested: ./tests/bugs/protocol/bug-1321578.t ./tests/features/ssl-authz.t - Ran tests on volumes with and without strict auth checking (as brick vol file needed to be edited to test, or rather to enable the option) - Ran tests on volumes to ensure existing mounts are disconnected when we enable strict checking Change-Id: I2ac4f0cfa5b59cc789cc5a265358389b04556b59 fixes: bz#1568844 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com> Signed-off-by: ShyamsundarR <srangana@redhat.com>
* shared storage: Prevent mounting shared storage from non-trusted clientMohammed Rafi KC2018-04-201-0/+21
| | | | | | | | | | | | | | | gluster shared storage is a volume used for internal storage for various features including ganesha, geo-rep, snapshot. So this volume should not be exposed to the client, as it is a special volume for internal use. This fix wont't generate non trusted volfile for shared storage volume.

* server: fix unresolved symbols by moving them to libglusterfsMohit Agrawal2018-04-205-104/+106
| | | | | | | | | | | | | | | | Problem: glusterd2 build is failed due to undefined symbol (xlator_mem_cleanup , glusterfsd_ctx) in server.so Solution: To resolve the same done below two changes 1) Move xlator_mem_cleanup code from glusterfsd-mgmt.c to xlator.c to be part of libglusterfs.so 2) replace glusterfsd_ctx to this->ctx because symbol glusterfsd_ctx is not part of server.so BUG: 1544090 Change-Id: Ie5e6fba9ed458931d08eb0948d450aa962424ae5 fixes: bz#1544090 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>

* features/bitrot: show the corresponding brick for the corrupted objectsRaghavendra Bhat2018-04-201-3/+8
| | | | | | | | | | | Currently with "gluster volume bitrot <volume name> scrub status" command the corrupted objects of a node are shown. But to what brick that corrupted object belongs to is not shown. Showing the brick of the corrupted object will help in situations where a node hosts multiple bricks of a volume.

* eventsapi: Handle Unicode string during signingAravinda VK2018-04-201-1/+1
| | | | | | | | | | | Python 2.7 HMAC does not support Unicode strings. Secret is read from file so it is possible that glustereventsd reads the content as Unicode. This patch converts the secret to `str` type before generating HMAC signature. Fixes: bz#1568820 Change-Id: I7daa64499ac4ca02544405af26ac8af4b6b0bd95 Signed-off-by: Aravinda VK <avishwan@redhat.com>
* Make glusterfsd binary print statedump & xlator dirPrashanth Pai2018-04-195-7/+49
| | | | | | | | | | | | | | | | | | | | | | | The glusterd2 needs following options, some of which are provided by gluster CLI today: --print-xlatordir --print-statedumpdir --print-logdir However, the CLI package need not be present on the machine running glusterd2. This change adds the above CLI options to glusterfsd binary which glusterd2 depends on.

* gluster: Sometimes Brick process is crashed at the time of stopping brickMohit Agrawal2018-04-1920-112/+365
| | | | | | | | | | | | | | | | | | | | | | | | Problem: Sometimes brick process is getting crashed at the time of stop brick while brick mux is enabled. Solution: Brick process was getting crashed because of rpc connection was not cleaning properly while brick mux is enabled.In this patch after sending GF_EVENT_CLEANUP notification to xlator(server) waits for all rpc client connection destroy for specific xlator.Once rpc connections are destroyed in server_rpc_notify for all associated client for that brick then call xlator_mem_cleanup for for brick xlator as well as all child xlators.To avoid races at the time of cleanup introduce two new flags at each xlator cleanup_starting, call_cleanup. BUG: 1544090 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> Note: Run all test-cases in separate build (https://review.gluster.org/#/c/19700/) with same patch after enable brick mux forcefully, all test cases are passed.

* glusterd: volume inode/fd status broken with brick muxhari gowtham2018-04-199-87/+119
| | | | | | | | | | | | | | | | | | | | | | | Problem: The values for inode/fd was populated from the ctx received from the server xlator. Without brickmux, every brick from a volume belonged to a single brick from the volume. So searching the server and populating it worked. With brickmux, a number of bricks can be confined to a single process. These bricks can be from different volumes too (if we use the max-bricks-per-process option). If they are from different volumes, using the server xlator to populate causes problem. Fix: Use the brick to validate and populate the inode/fd status.
