* protocol: don't use allocaAmar Tumballi2018-09-052-103/+58
| | | | | | | | | | | | current implementation of alloca can cause issues when strings larger than the allocated buffer is passed to the xdr. Hence it makes sense to allow XDR decode functions to deal with memory allocations, which we can free later. Fixes: bz#1625097 Change-Id: I3a05553f5702de9575c244649ca0e5ac9abaac94 Signed-off-by: Amar Tumballi <amarts@redhat.com>

* build: add --enable-asan configure optionsNiels de Vos2018-08-301-1/+1
| | | | | | | | | | | | | | Introduce a `./configure --enable-asan` to build with `-fsanitize=address -fno-omit-frame-pointer` options. This uses the libasan.so shared library, so that needs to be available. While running builds with the ASAN options, several linker issues surfaced and these have been addressed with this change as well. Building with --enable-asan has been tested on Fedora 28.

* build: rename event.h to gf-event.hNiels de Vos2018-07-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Newer FreeBSD versions (noticed with 10.3-RELEASE) provide a event.h file that on occasion gets included instead of the libglusterfs file. When this happens, 'struct event_pool' will not be defined and building will fail with errors like: autoscale-threads.c:18:55: error: incomplete definition of type 'struct event_pool' int thread_count = pool->eventthreadcount; ~~~~^ autoscale-threads.c:17:16: note: forward declaration of 'struct event_pool' struct event_pool *pool = ctx->event_pool; ^ This problem is caused by 'pkg-config --cflags uuid' that adds /usr/local/include to the GF_CPPFLAGS. The use of libuuid is preferred so that the contrib/uuid/ directory can be removed. By renaming event.h to gf-event.h there is no conflict between the different event.h files anymore and compiling on FreeBSD works without issues.

* server: Set ssl-allow option in options table and rename IDPrashanth Pai2018-07-111-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change explicitly adds 'ssl-allow' options to the server xlator's options table so that glusterd2 can see it as a settable option. This change also marks 'auth.allow' and 'auth.reject' options as a settable. Glusterd2 doesn't maintain a separate volume options table. Glusterd2 dynamically loads shared objects of xlators to read their option table and other information. Glusterd2 reads 'xlator_api_t' if available. If that's not available, it falls back to reading just the options table directly. In glusterd2, volume set operations are performed by users on keys of the format <xlator>.<option-name>. Glusterd2 uses xlator name set in 'xlator_api_t.identifier'. If that's not present it will use the shared object's file name as xlator name. Hence, it is important for 'xlator_api_t.identifier' to be set properly, and in this case, the proper value is "server". This name shall be used by users as prefix while setting volume options implemented in server xlator. The name will also be used in volfile. A user in glusterd2 can authorize a client over TLS as follows: $ glustercli volume set <volname> server.ssl-allow <client1-CN>[,<clientN-CN>] gd2 References: https://github.com/gluster/glusterd2/issues/971 https://github.com/gluster/glusterd2/issues/214 https://github.com/gluster/glusterd2/pull/967 Updates: bz#1193929 Change-Id: I59ef58acb8d51917e6365a83be03e79ae7c5ad17 Signed-off-by: Prashanth Pai <ppai@redhat.com>

* protocol/server: don't assume there would be a volfile idAmar Tumballi2018-05-081-1/+9
| | | | | | | | | | | | | | | | | | | | | Earlier glusterfs never had an assumption someone would start it with right arguments, and brick processes would be spawned by a management layer. It just assume the role based on the volfile. Other than volfile, no other arguments should be technically mandatory for working of glusterfs. With this patch, that assumption holds true. Updates: github issue # 352 A note on why this particular issue for this basic sanity? As per the design of thin-arbiter/tie-breaker, it can be started independently on any machine, without need of glusterd. So, similar to 'glusterd', we should be able to spawn a process with any translator without options/volume id etc. fixes: bz#1569399 Change-Id: I5c0650fe0bfde35ad94ccba60e63f6cdcd1ae5ff Signed-off-by: Amar Tumballi <amarts@redhat.com>

* 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.

* server/auth: add option for strict authenticationMohammed Rafi KC2018-04-204-4/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When this option is enabled, we will check for a matching username and password, if not found then the connection will be rejected. This also does a checksum validation of volfile The option is invalid when SSL/TLS is in use, at which point the SSL/TLS certificate user name is used to validate and hence authorize the right user. 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>

* gluster: Sometimes Brick process is crashed at the time of stopping brickMohit Agrawal2018-04-193-49/+148
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* glusterd: volume inode/fd status broken with brick muxhari gowtham2018-04-191-42/+50
| | | | | | | | | | | | | | | | | | | | | | | 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.

* protocol: Fix 4.0 client, parsing older iatt in dictShyamsundarR2018-03-103-44/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | In a mixed mode cluster involving 4.0 and older 3.x bricks, if clients are newer, then the iatt encoded in the dictionary can be of the older iatt format, which a newer client will map incorrectly to the newer structure. This causes failures in FOPs that depend on this iatt for some functionality (seen in mkdir operations failing as EIO, when DHT hits its internal setxattr call). The fix provided is to convert the iatt in the dict, based on which RPC version is used to communicate with the server. IOW, this is the reverse of change in commit "b966c7790e" Tested using a mixed mode cluster (i.e bricks in 3.12 and 4.0 versions) and a mixed set of clients, 3.12 and 4.0 clients. There is no regression test provided, as this needs a mixed mode cluster to test and validate.

* protocol/server: Fix "auth-path" in options tableKotresh HR2018-01-221-0/+5
| | | | | | | | | | | Options set will crash the brick with glusterd2. glusterd used to set "auth-path" during volfile generation. With glusterd2, it should come from options table. Updates: #302 Change-Id: Ie41a17779c185b87ace7e0bce0d0ba594b415a75 Signed-off-by: Kotresh HR <khiremat@redhat.com>
* protocol: make on-wire-change of protocol using new XDR definition.Amar Tumballi2018-01-198-346/+8598
| | | | | | | | | | | | | | | | | | | | | | With this patchset, some major things are changed in XDR, mainly: * Naming: Instead of gfs3/gfs4 settle for gfx_ for xdr structures * add iattx as a separate structure, and add conversion methods * the *_rsp structure is now changed, and is also reduced in number (ie, no need for different strucutes if it is similar to other response). * use proper XDR methods for sending dict on wire. Also, with the change of xdr structure, there are changes needed outside of xlator protocol layer to handle these properly. Mainly because the abstraction was broken to support 0-copy RDMA with payload for write and read FOP. This made transport layer know about the xdr payload, hence with the change of xdr payload structure, transport layer needed to know about the change.

* rpc/*: auth-header changesAmar Tumballi2018-01-171-0/+3
| | | | | | | | | | | | | | | | | Introduce another authentication header which can now send more data. This is useful because this data can be common for all the fops, and we don't need to change all the signatures. As part of this, made rpc-clnt.c little more modular to support multiple authentication structures. stack.h changes are placeholder for the ctime etc, can be moved later based on need. updates #384 Change-Id: I6111c13cfd2ec92e2b4e9295896bf62a8a33b2c7 Signed-off-by: Amar Tumballi <amarts@redhat.com>

* locks: added inodelk/entrylk contention upcall notificationsXavier Hernandez2018-01-161-6/+38
| | | | | | | | | | | | | | The locks xlator now is able to send a contention notification to the current owner of the lock. This is only a notification that can be used to improve performance of some client side operations that might benefit from extended duration of lock ownership. Nothing is done if the lock owner decides to ignore the message and to not release the lock. For forced release of acquired resources, leases must be used.

* rio/everywhere: add icreate/namelink fopSusant Palai2017-12-051-0/+234
| | | | | | | | | | | | | | | | | | | | | icreate creates inode, while namelink links the basename to it's parent gfid. For now mkdir is the primary user of these fops. Better distribution is acheived by creating the inode on ,(say) mds1 and linking the basename to it's parent gfid on mds2. The inode serves readdirp, stat etc. More details about the fops are present at: https://review.gluster.org/#/c/13395/3/design/DHT2/DHT2_Icreate_Namelink_Notes.md This backport of three patches from experimental branch. 1- https://review.gluster.org/#/c/18085/ 2- https://review.gluster.org/#/c/18086/ 3- https://review.gluster.org/#/c/18094/ Updates gluster/glusterfs#243 Change-Id: I1bd3d5a441a3cfab1acfeb52f15c6c867d362592 Signed-off-by: Susant Palai <spalai@redhat.com>
* libglusterfs: fix the call_stack_set_group() functionCsaba Henk2017-11-241-34/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - call_stack_set_group() will take the ownership of passed buffer from caller; - to indicate the change, its signature is changed from including the buffer directly to take a pointer to it; - either the content of the buffer is copied to the groups_small embedded buffer of the call stack, or the buffer is set as groups_large member of the call stack; - the groups member of the call stack is set to, respectively, groups_small or groups_large, according to the memory management conventions of the call stack; - the buffer address is overwritten with junk to effectively prevent the caller from using it further on. Also move call_stack_set_group to stack.c from stack.h to prevent "defined but not used [-Wunused-function]" warnings (not using it anymore in call_stack_alloc_group() implementation, which saved us from this so far). protocol/server: refactor gid_resolve() In gid_resolve there are two cases: either the gid_cache_lookup() call returns a value or not. The result is caputured in the agl variable, and throughout the function, each particular stage of the implementation comes with an agl and a no-agl variant. In most cases this is explicitly indicated via an if (agl) { ... } else { ... } but some of this branching are expressed via goto constructs (obfuscating the fact we stated above, that is, each particular stage having an agl/no-agl variant). In the current refactor, we bring the agl conditional to the top, and present the agl/non-agl implementations sequentially. Also we take the opportunity to clean up and fix the agl case: - remove the spurious gl.gl_list = agl->gl_list; setting, as gl is not used in the agl caae - populate the group list of call stack from agl, fixing thus referred BUG.
