* gfapi : Handle the path == "" glfs_resolve_atJiffin Tony Thottan2018-08-171-7/+10
| | | | | | | | | | | | | | | | Currently there is no check for path = "" in glfs_resolve_at. So if application sends an empty path, then the function resolves into the parent inode which is incorrect. Plus modified possible of "path" with "origpath" in the same function. >Change-Id: Ie5ff9ce4b771607b7dbb3fe00704fe670421792a >fixes: bz#1610236 >Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com> >(cherry picked from commit febee007bb1a99d65300630c2a98cbb642b1c8dc) Change-Id: Ie5ff9ce4b771607b7dbb3fe00704fe670421792a fixes: bz#1618348 Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com>
* gfapi: various broken symbol versionsKaleb S. KEITHLEY2018-06-112-1/+5
| | | | | | | | | | | | | | | | | | | | | lots of breakage in symbol versions: symbols added in 4.1 incorrectly, and symbols added in 4.1 but labeled 4.0.0, and Not noticed until someone tried to build 3.13.2 on FreeBSD 11.1, despite the fact that we build on FreeBSD 10.3 IIRC, somehow the 3.13 errors aren't a build error there. Note: in rereading the Ulrich Drepper write-up I noticed that when a symbol version is changed, you are supposed to leave the old symbol in its original section in addition to adding it to its new section. Adding back those symbols to their original sections. Reported-by: Roman Serbski <mefystofel@gmail.com> Change-Id: I9a883546d08e0847f7228d8ea5943bc54275b319 BUG: 1577164 Signed-off-by: Kaleb S.

* gfapi: set lkowner in glfdSoumya Koduri2017-10-255-1/+87
| | | | | | | | | | | | | | | | | | We need a provision to be able to set lkowner (which is used to distinguish locks maintained by server) in gfapi. Since the same lk_owner need to be used to be able to flush the lock while closing the fd, store the lkowner in the glfd structure itself. A new API has been added to be able to set lkowner in glfd. This is backport of below mainline fix - https://review.gluster.org/#/c/18429 https://review.gluster.org/#/c/18522/ Change-Id: I67591d6b9a89c20b9617d52616513ff9e6c06b47 BUG: 1501956 Signed-off-by: Soumya Koduri <skoduri@redhat.com>
* gfapi: Duplicate the buffer sent in setxattr callsPoornima G2017-08-123-6/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: The caller of glfs_setxattr sends a buffer to set as the value. We create a dict in which the pointer to the value is set. Underlying layers like md-cache take a ref on this dict to store the value for a longer time. But the moment setxattr is complete, the caller of glfs_setxattr can free the value memory. Solution: memcpy the setxattr value to the gluster buffer. > Reviewed-on: https://review.gluster.org/17967 > Reviewed-by: soumya k <skoduri@redhat.com> > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Jeff Darcy <jeff@pl.atyp.us> > (cherry picked from commit e11296f8e52b7e3b13d21b41d4fa34baea878edf) Change-Id: I58753fe702e8b7d0f6c4f058714c65d0ad5d7a0a BUG: 1479655 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: https://review.gluster.org/18001 Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>

* gfapi: mark glfs_ipc() for internal use onlyNiels de Vos2017-07-285-20/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 3.7 version of glfs_ipc() has never been used by external applications. There is little use for internal xlator communication that is triggered from outside of core GlusterFS executables. This function has now been removed from libgfapi.so. For Gluster 4.0 a new variation for glfs_ipc() has been added. The function expects dict_t parameters, which are currently not available for external applications. There is no sense in providing glfs_ipc() for non-core GlusterFS executables. Therefore, glfs_ipc() has been marked as private, and the declaration is now in the glfs-internal.h header. The Python test case (tests/features/ipctest.py) is not correct and will be re-written in C to prevent portability issues. This test is currently disabled (commit d26f0bac149d495fa93710c3f7b6b63c36cb8387).

* mem-pool: initialize pthread_key_t pool_key in mem_pool_init_early()Niels de Vos2017-07-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is not possible to call pthread_key_delete for the pool_key that is intialized in the constructor for the memory pools. This makes it difficult to do a full cleanup of all the resources in mem_pools_fini(). For this, the initialization of pool_key should be moved to mem_pool_init(). However, the glusterfsd binary has a rather complex initialization procedure. The memory pools need to get initialized partially to get mem_get() functionality working. But, the pool_sweeper thread can get killed in case it is started before glusterfsd deamonizes. In order to solve this, mem_pools_init() is split into two pieces: 1. mem_pools_init_early() for initializing the basic structures 2. mem_pools_init_late() to start the pool_sweeper thread With the split of mem_pools_init(), and placing the pthread_key_create() in mem_pools_init_early(), it is now possible to correctly cleanup the pool_key with pthread_key_delete() in mem_pools_fini(). It seems that there was no memory pool initialization in the CLI. This has been added as well now. Without it, the CLI will not be able to call mem_get() successfully which results in a hang of the process.

* gfapi: prevent mem-pool leak in case glfs_new_fs() failsNiels de Vos2017-07-121-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | Commit 7039243e187 adds a call to mem_pools_init() so that the memory pool cleanup thread ("sweeper") is started. However, now it is possible that users of gfapi can not cleanup this thread because glfs_new() can return NULL, but the sweeper is still running. In case glfs_fs_new() fails, mem_pools_fini() needs to be called as well. This seems more correct than calling mem_pools_init() after glfs_fs_new(), and this makes using memory pools possible *really* early in the gfapi initialization.

* mgtm/core : use sha hash function for volfile checkMohammed Rafi KC2017-07-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are storing the entire volfile and using this to check volfile change. With brick multiplexing there will be lot of graphs per process which will increase the memory foot print of the process. So instead of storing the entire graph we could use sha256 and we can compare the hash to see whether volfile change happened or not. Also with Brick multiplexing, the direct comparison of vol file is not correct. There are two problems. Problem 1: We are currently storing one single graph (the last updated volfile) whereas, what we need is the entire graph with all atttached bricks. If we fix this issue, we have second problem Problem 2: With multiplexing we have a graph that contains multiple bricks. But what we are checking as part of the reconfigure is, comparing the entire graph with one single graph, which will always fail. Solution: We create list in glusterfs_ctx_t that stores sha256 hash of individual brick graphs. When a graph changes happens we compare the stored hash and the current hash. If the hash matches, then no need for reconfigure. Otherwise we first do the reconfigure and then update the hash. For now, gfapi has not changed this way. Meaning when gfapi volfile fetch or reconfigure happens, we still store the entire graph and compare, each memory. This is fine, because libgfapi will not load brick graphs. But changing the libgfapi will make the code similar in both glusterfsd-mgmt and api. Also it helps to reduce some memory.

| | | | | | | | | | | | | | | | | | | | | | | | These are both needed because GFAPI clients are a bit unique. They can be long-running, so they can potentially benefit from the memory reclamation that mem_pools_init will enable. On the other hand, they might completely tear down their Gluster environment well before the process exits, so they need mem_pools_fini as well. Our main and auxiliary daemons do need mem_pools_init but don't need to call it themselves because that's handled for them in glusterfsd.c right after they daemonize. They don't need mem_pools_fini, because the only place they could *safely* call it is right before exit and then it won't do them any good. Transient processes (e.g. gf_attach) don't benefit from either because, well, they're transient. They'll be gone before memory reclamation matters.

* gfapi/handleops: Introducing glfs_xreaddirplus_r() fop for handleopsSoumya Koduri2017-05-0210-4/+303

But often applications may need extra information, like for eg., NFS-Ganesha which operates on handles needs handles for each of those dirents returned. So this would require extra calls to the backend, in this case LOOKUP (which is very expensive operation) resulting in very low readdir performance. To address that introducing this new API using which applications can make request for any extra information to be returned as part of readdirplus response. Currently this new api returns stat and handles as demanded by application. The synopsis of the API is noted in glfs.h. @todo: * Enhance test script using this new API Below were the perf results on single brick volume with and without these changes - Dataset used - 10*100 directories and each directory containing 100 empty files.

| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.

This can lead to dead lock if we consume all the epoll threads. In general any call-back function executed in epoll thread should not call any blocking call which waits on a network reply either directly or indirectly, e.g. syncop functions should not be called in these threads. As a fix we should not wait for migration in the call-back path.

* gfapi: async fops should unref in callbacksRaghavendra Talur2016-11-051-18/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If fd is unref'd at the end of async call then the unref in cbks would lead to double unref and possible crash. Removing duplicate unrefs. Added unref only in failure cases. A simple test case has been added to test async write case. Need to extend the same for other async APIs too. Details: All glfd based calls in libgfapi, except for glfs_open and glfs_close, behave in the same way. At the start of the operation, they take a ref on glfd and fd. At the end of the operation, they unref it. Async calls are a little different as they unref in the cbk function. A successfull open call does not unref either the glfd or fd, thereby functioning as a reference for a OPEN file object. glfs_close makes a syncop_flush call sandwiched between a fd ref and unref(this can be removed, more on this below), followed by a call to glfs_mark_glfd_for_deletion which unrefs glfd and also calls glfs_fd_destroy as a release function thereby doing a unref on fd too. Functionally, there is no problem with how everything works when as described above. However, it is a little non-intuitive that we need to perform a fd_unref as a consequence of a implicit fd_ref that happens within glfs_resolve_fd. As we perform a GF_REF_GET(glfd) at the start of every operation, it would be worthwhile to remove the fd_ref that glfs_resovle_fd takes and do away with explicit fd_unref()s at the end of every operation. This is the same reason why we don't need the fd_ref in glfs_close. This is however not in the scope of this patch.

* gfapi: warn when glfs_realpath() returned malloc'd memoryNiels de Vos2016-10-115-10/+50
| | | | | | | | | | | | | | | | | | | | | | | | glfs_realpath() may return memory allocated with malloc(). Depending on the memory allocator that the application uses, calling free() on the returned string can cause segmentation faults or other problems. Functions that allocate memory, need to match the free'ing of the same memory allocator and memory accounting. glibc/malloc and jemalloc/free do not match together (other allocators could probably trigger these problems as well). Applications need to provide a pre-allocated buffer, or in case glfs_realpath() allocates the memory, glfs_free() should be used to free it.

* gfapi: redesign the public interface for upcall consumersNiels de Vos2016-09-287-98/+424
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The glfs_callback_arg and glfs_callback_inode_arg were allocated by gfapi, and expected to be free()'d by the application. However it is not reasonable to expect that applications use the same memory allocator to as the compiled libgfapi.so. For instance, it is possible that gfapi uses glibc malloc/free, and an application like NFS-Ganesha the versions from jemalloc. Mismatching of the malloc() and free() functions causes segmentation faults at best. In order to prevent problems like this in the future, the API for applications that consume upcalls has been remodeled. Any of the structures that gfapi allocates, should be free'd with glfs_free(). The members of the structures can not be accessed directly anymore, each has its own function to access now. Correcting the naming of the functions, structures and constants is a continuation of commit 2775dc64101ed37c8d9809bf9852dbf0746ee2b6. These new improvements not only have correct prefixes for the functions and structures, the naming also reflects more to the upcall framework and does not use "callback" anymore.

Rewrite the make rules to do what xdrgen does. Now we can get rid of xdrgen. Note 1. netbsd6's sed doesn't do -i. Why are we still running smoke tests on netbsd6 and not netbsd7? We barely support netbsd7 as it is. Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with libglusterfs? A cut-and-paste mistake? It has no references to symbols in libglusterfs. Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_ regex that matches the same lines as the _extended_ regex "/#(ifndef|define|endif)/". To match the extended regex sed needs to be run with -r on Linux; with -E on *BSD. However NetBSD's and FreeBSD's sed helpfully also provide -r for compatibility. Using a basic regex avoids having to use a kludge in order to run sed with the correct option on OS X. Note 4. Not copying the bit of xdrgen that inserts copyright/license boilerplate. AFAIK it's silly to pretend that machine generated files like these can be copyrighted or need license boilerplate. The XDR source files have their own copyright and license; and their copyrights are bound to be more up to date than old boilerplate inserted by a script. From what I've seen of other Open Source projects -- e.g. gcc and its C parser files generated by yacc and lex -- IIRC they don't bother to add copyright/license boilerplate to their generated files. It appears that it's a long-standing feature of make (SysV, BSD, gnu) for out-of-tree builds to helpfully pretend that the source files it can find in the VPATH "exist" as if they are in the $cwd. rpcgen doesn't work well in this situation and generates files with "bad" #include directives. E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`, you get an #include directive in the generated .c file like this: ... #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h" ... which (obviously) results in compile errors on out-of-tree build because the (generated) header file doesn't exist at that location. Compared to `rpcgen ./glusterfs3-xdr.x` where you get: ... #include "glusterfs3-xdr.h" ... Which is what we need. We have to resort to some Stupid Make Tricks like the addition of various .PHONY targets to work around the VPATH "help". Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/... looks exactly like -I$(top_srcdir)/rpc/xdr/... Don't be fooled though. And don't delete the -I$(top_builddir)/rpc/xdr/... bits Change-Id: Iba6ab96b2d0a17c5a7e9f92233993b318858b62e BUG: 1330604 Signed-off-by: Kaleb S KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/14085 Tested-by: Niels de Vos <ndevos@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com>
* md-cache: Register the list of xattrs with cache-invalidationPoornima G2016-08-301-22/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: md-cache caches a specified list of xattrs, and when cache invalidation is enabled, it makes sense to recieve invalidation only when those xattrs are modified by other clients. But the current implementation of upcall is that, it will send invalidation when any of the on-disk xattrs is modified. Solution: md-cache sends a list of xattrs that it is interested in, to upcall by issuing an ipc(). The challenge here is to make sure everytime a brick goes offline and comes back up, the ipc() needs to be issued to the bricks. Hence ipc() is sent from md-cache every time there is a CHILD_UP/CHILD_MODIFIED event. TODO: There will be patches following, in cluster xlators, to implement ipc fop.
