* glfs-mgmt: fix connecting to multiple volfile transportsPrasanna Kumar Kalever2016-03-241-26/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: [ {"host":"1.2.3.4", "port":"24007", "transport":"tcp"}, {"host":"/var/run/glusterd.socket", "transport":"unix"} ] Consider the above case where we have two volfile servers, each has different transport type, we first try to connect to server1 which has transport type "tcp" let's say we found that host address is invalid, now we pick the next available server2, in our case it is of type "unix" and try to connect to it. but we fail to connect to it even we have right unix path, because multiple volfile servers with different transport type is not taken care currently. Solution: Every time we receive a RPC_CLNT_DISCONNECT event in mgmt_rpc_notify, we need to check the transport type of the volfile server in the list and set the keys "transport.socket.connect-path" or "remote-host" accordingly.

* gfapi: Use inode_forget in case of handle objectsSoumya Koduri2016-02-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently with gfapi, even if applications release their reference on paritular inode entries, those entries never get destroyed as they shall always have positive nlookup count unless inode_table exceeds lru limit. Since inodes and their contexts can consume considerable amount of memory, applications may end up consuming lot of memory and may even get OOM killed. To avoid that, have considered below approaches (for handle based access)- a) Do 'inode_lookup' only if the corresponding inode is created for the first time and forget it during close of the handle This shall not work as multiple handle objects can refer to same inode entry and inode_forget from second handle object onwards shall result in assert. b) Do 'inode_lookup' during a handle or fd creation But this approach shall affect the performance of the fops which operate on neither handle nor fd. c) current approach taken- Applications using glfs handle objects hold a reference on corresponding inode entries. Hence it is safe to forget those inodes and make nlookup count to '0' while trying to delete those handle objects. That way the last unref (i.e, from the last handle close) shall result in inode_destroy().

* glusterd: Bug fixes for IPv6 supportNithin D2016-02-201-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Glusterd not working using ipv6 transport. The idea is with proper glusterd.vol configuration, 1. glusterd needs to listen on default port (240007) as IPv6 TCP listner. 2. Volume creation/deletion/mounting/add-bricks/delete-bricks/peer-probe needs to work using ipv6 addresses. 3. Bricks needs to listen on ipv6 addresses. All the above functionality is needed to say that glusterd supports ipv6 transport and this is broken. Fix: When "option transport.address-family inet6" option is present in glusterd.vol file, it is made sure that glusterd creates listeners using ipv6 sockets only and also the same information is saved inside brick volume files used by glusterfsd brick process when they are starting. Tests Run: Regression tests using ./run-tests.sh IPv4: Ran manually till tests/basic/rpm.t . IPv6: (Need to add the above mentioned config and also add an entry for "hostname ::1" in /etc/hosts) Started failing at ./tests/basic/glusterd/arbiter-volume-probe.t and ran successfully till here Unit Tests using Ipv6 peer probe add-bricks remove-bricks create volume replace-bricks start volume stop volume delete volume Change-Id: Iebc96e6cce748b5924ce5da17b0114600ec70a6e BUG: 1117886 Signed-off-by: Nithin D <nithind1988@yahoo.in> Reviewed-on: http://review.gluster.org/11988 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>

* libgfapi: glfd close is not correctly handled for async fopRajesh Joseph2016-02-104-40/+224
| | | | | | | | | | | | | | | | | | | | | | | There is chance that before the async fop is complete client can send a close. libgfapi destroys glfd on close. Therefore it can lead to crash or unexpected behaviour when the pening fop reaches libgfapi layer. Currently we don't provide any api to cancel these outstanding fops neither we check if the glfd is already closed or not. Therefore as a fix provided refcount for glfd. Each fop (sync or async) will take a ref and once the fop is complete it will unref the refcount. We should not call the registered callback function if glfd is already closed. To achieve this we maintain state of glfd so that we can safely take a call if the fd is closed or not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've been lucky that we haven't had any symbol collisions until now. Now we have a collision between the snapview-client's svc_lookup() and libntirpc's svc_lookup() with nfs-ganesha's FSAL_GLUSTER and libgfapi. As a short term solution all the snapview-client's FOP methods were changed to static scope. See http://review.gluster.org/11805. This works in snapview-client because all the FOP methods are defined in a single source file. This solution doesn't work for other xlators with FOP methods defined in multiple source files. To address this we link with libtool's '-export-symbols $symbol-file' (a wrapper around `ld --version-script ...` --- on linux anyway) and only export the minimum required symbols from the xlator sharedlib. N.B. the libtool man page says that the symbol file should be named foo.sym, thus the rename of *.exports to *.sym. While foo.exports worked, we will follow the documentation. Signed-off-by: Kaleb S.

* rpc: add owner xlator argument to rpc_clnt_newKrishnan Parthasarathi2015-08-122-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The @owner argument tells RPC layer the xlator that owns the connection and to which xlator THIS needs be set during network notifications like CONNECT and DISCONNECT. Code paths that originate from the head of a (volume) graph and use STACK_WIND ensure that the RPC local endpoint has the right xlator saved in the frame of the call (callback pair). This guarantees that the callback is executed in the right xlator context. The client handshake process which includes fetching of brick ports from glusterd, setting lk-version on the brick for the session, don't have the correct xlator set in their frames. The problem lies with RPC notifications. It doesn't have the provision to set THIS with the xlator that is registered with the corresponding RPC programs. e.g, RPC_CLNT_CONNECT event received by protocol/client doesn't have THIS set to its xlator. This implies, call(-callbacks) originating from this thread don't have the right xlator set too. The fix would be to save the xlator registered with the RPC connection during rpc_clnt_new. e.g, protocol/client's xlator would be saved with the RPC connection that it 'owns'. RPC notifications such as CONNECT, DISCONNECT, etc inherit THIS from the RPC connection's xlator.

* libgfapi: send explicit lookups on inodes linked in readdirpRaghavendra Bhat2015-07-022-14/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | If the inode is linked via readdirp, then the consuners of gfapi which are using handles (got either in lookup or readdirp) might not send an explicit lookup on that object again (ex: NFS, samba, USS). If there is a replicate volume where the replicas of the object are not in sync, then readdirp followed by fops might lead data being served from the subvolume which is not in sync with latest data. And since lookup is needed to trigger self-heal on that object the consumers might keep getting wrong data until an explicit lookup is not done. Fuse handles this situation by sending an explicit lookup by itself (fuse xlator) on those inodes which are linked via readdirp, whenever a fop comes on that inode. The same procedure is done in gfapi as well to address this situation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | At present stage, the initialization and destroy of conditional and mutex variables of glfs struct happen in different places and there is no uniform way of destroying these variables incase there is a failure when initializing these. The fs mutex and conditional variables are getting destroyed from glfs_free_from_ctx(). However this destroy is not done by a conditional check inside destroy function. By introducing bit flags in glfs object, we can make use of the same (if there is a failure in initialization) in glfs_fini() which is evolving as one and only function to free fs and ctx resources. This patch introduce the flags field and set the flags according to the initialization flow of the mutex and conditional variables of struct glfs members. Without this patch we are compelled to use the goto lables and other hacks in init functions to make sure the resources are freed if there is an error path.

* core: use reference counting for mem_acct structuresJeff Darcy2015-05-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When freeing memory, our memory-accounting code expects to be able to dereference from the (previously) allocated block to its owning translator. However, as we have already found once in option validation and twice in logging, that translator might itself have been freed and the dereference attempt causes on of our daemons to crash with SIGSEGV. This patch attempts to fix that as follows: * We no longer embed a struct mem_acct directly in a struct xlator, but instead allocate it separately. * Allocated memory blocks now contain a pointer to the mem_acct instead of the xlator. * The mem_acct structure contains a reference count, manipulated in both the normal and translator allocate/free code using atomic increments and decrements. * Because it's now a separate structure, we can defer freeing the mem_acct until its reference count reaches zero (either way). * Some unit tests were disabled, because they embedded their own copies of the implementation for what they were supposedly testing. Life's too short to spend time fixing tests that seem designed to impede progress by requiring a certain implementation as well as behavior.
