* Multiple files: reduce work while under lock.Yaniv Kaul2019-01-291-5/+5
| | | | | | | | | | | | | | | | | Mostly, unlock before logging. In some cases, moved different code that was not needed to be under lock (for example, taking time, or malloc'ing) to be executed before taking the lock. Note: logging might be slightly less accurate in order, since it may not be done now under the lock, so order of logs is racy. I think it's a reasonable compromise.

* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

* all: fix the format string exceptionsAmar Tumballi2018-11-051-4/+5
| | | | | | | | | | | | | | | | Currently, there are possibilities in few places, where a user-controlled (like filename, program parameter etc) string can be passed as 'fmt' for printf(), which can lead to segfault, if the user's string contains '%s', '%d' in it. While fixing it, makes sense to make the explicit check for such issues across the codebase, by making the format call properly.

* gluster: Sometimes Brick process is crashed at the time of stopping brickMohit Agrawal2018-04-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* storage/posix: Add active-fd-count option in glusterPranith Kumar K2018-03-211-0/+2
| | | | | | | | | | | | | | | | | | | | Problem: when dd happens on sharded replicate volume all the writes on shards happen through anon-fd. When the writes don't come quick enough, old anon-fd closes and new fd gets created to serve the new writes. open-fd-count is decremented only after the fd is closed as part of fd_destroy(). So even when one fd is on the way to be closed a new fd will be created and during this short period it appears as though there are multiple fds opened on the file. AFR thinks another application opened the same file and switches off eager-lock leading to extra latency. Fix: Have a different option called active-fd whose life cycle starts at fd_bind() and ends just before fd_destroy() BUG: 1557932 Change-Id: I2e221f6030feeedf29fbb3bd6554673b8a5b9c94 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>
* glusterfs: Use gcc builtin ATOMIC operator to increase/decreate refcount.Mohit Agrawal2017-12-121-20/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In glusterfs code base we call mutex_lock/unlock to take reference/dereference for a object.Sometime it could be reason for lock contention also.

| | | | | | | | | | | To resolve a fd from client requests, need to take a mutex lock for the fdtable to do the lookup.

| | | | | | | | | | | | | | | | | | | | | | | | | There are three kinds of inline functions: plain inline, extern inline, and static inline. All three have been removed from .c files, except those in "contrib" which aren't our problem. Inlines in .h files, which are overwhelmingly "static inline" already, have generally been left alone. Over time we should be able to "lower" these into .c files, but that has to be done in a case-by-case fashion requiring more manual effort. This part was easy to do automatically without (as far as I can tell) any ill effect. In the process, several pieces of dead code were flagged by the compiler, and were removed.

Then the graph would have changed, thus the xl count.

* protocol/client,server: fcntl lock self healing.Mohammed Junaid2012-02-201-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently(with out this patch), on a disconnect the server cleans up the transport which inturn closes the fd's and releases the locks acquired on those fd's by that client. On a reconnect, client just reopens the fd's but doesn't reacquire the locks. The application that had previously acquired the locks still is under the assumption that it is the owner of those locks which might have been granted to other clients(if they request) by the server leading to data corruption. This patch allows the client to reacquire the fcntl locks (held on the fd's) during client-server handshake. * The server identifies the client via process-uuid-xl (which is a combination of uuid and client-protocol name, it is assumed to be unique) and lk-version number. * The client maintains a list of process-uuid-xl, lk-version pair for each accepted connection. On a connect, the server traverses the list for a matching pair, if a matching pair is not found the the server returns lk-version with value 0, else it returns the lk-version it has in store. * On a disconnect, the server and client enter grace period, and on the completion of the grace period, the client bumps up its lk-version number (which means, it will reacquire the locks the next time) and the server will distroy the connection. If reconnection happens within the grace period, the server will find the matching (process-uuid-xl, lk-version) pair in its list which guarantees that the fd's and there corresponding locks are still valid for this client. Configurable options: To set grace-timeout, the following options are option server.grace-timeout value option client.grace-timeout value To enable or disable the lk-heal, option lk-heal [on|off] gluster volume set command can be used to configurable options Change-Id: Id677ef1087b300d649f278b8b2aa0d94eae85ed2 BUG: 795386 Signed-off-by: Mohammed Junaid <junaid@redhat.com> Reviewed-on: http://review.gluster.com/2766 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>

* core: GFID filehandle based backend and anonymous FDsAnand Avati2012-01-201-34/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. What -------- This change introduces an infrastructure change in the filesystem which lets filesystem operation address objects (inodes) just by its GFID. Thus far GFID has been a unique identifier of a user-visible inode. But in terms of addressability the only mechanism thus far has been the backend filesystem path, which could be derived from the GFID only if it was cached in the inode table along with the entire set of dentry ancestry leading up to the root. This change essentially decouples addressability from the namespace. It is no more necessary to be aware of the parent directory to address a file or directory. 2. Why ------- The biggest use case for such a feature is NFS for generating persistent filehandles. So far the technique for generating filehandles in NFS has been to encode path components so that the appropriate inode_t can be repopulated into the inode table by means of a recursive lookup of each component top-down. Another use case is the ability to perform more intelligent self-healing and rebalancing of inodes with hardlinks and also to detect renames. A derived feature from GFID filehandles is anonymous FDs. An anonymous FD is an internal USABLE "fd_t" which does not map to a user opened file descriptor or to an internal ->open()'d fd. The ability to address a file by the GFID eliminates the need to have a persistent ->open()'d fd for the purpose of avoiding the namespace. This improves NFS read/write performance significantly eliminating open/close calls and also fixes some of today's limitations (like keeping an FD open longer than necessary resulting in disk space leakage) 3. How ------- At each storage/posix translator level, every file is hardlinked inside a hidden .glusterfs directory (under the top level export) with the name as the ascii-encoded standard UUID format string. For reasons of performance and scalability there is a two-tier classification of those hardlinks under directories with the initial parts of the UUID string as the directory names. For directories (which cannot be hardlinked), the approach is to use a symlink which dereferences the parent GFID path along with basename of the directory. The parent GFID dereference will in turn be a dereference of the grandparent with the parent's basename, and so on recursively up to the root export. 4. Development --------------- 4a. To leverage the ability to address an inode by its GFID, the technique is to perform a "nameless lookup". This means, to populate a loc_t structure as: loc_t { pargfid: NULL parent: NULL name: NULL path: NULL gfid: GFID to be looked up [out parameter] inode: inode_new () result [in parameter] } and performing such lookup will return in its callback an inode_t populated with the right contexts and a struct iatt which can be used to perform an inode_link () on the inode (without a parent and basename). The inode will now be hashed and linked in the inode table and findable via inode_find(). A fundamental change moving forward is that the primary fields in a loc_t structure are now going to be (pargfid, name) and (gfid) depending on the kind of FOP. So far path had been the primary field for operations. The remaining fields only serve as hints/helpers. 4b. If read/write is to be performed on an inode_t, the approach so far has been to: fd_create(), STACK_WIND(open, fd), fd_bind (in callback) and then perform STACK_WIND(read, fd) etc. With anonymous fds now you can do fd_anonymous (inode), STACK_WIND (read, fd). This results in great boost in performance in the inbuilt NFS server. 5. Misc ------- The inode_ctx_put[2] has been renamed to inode_ctx_set[2] to be consistent with the rest of the codebase.

* statedump: do not print the inode number in the statedumpRaghavendra Bhat2011-10-011-10/+3
