| | | | | | | | | | | | | | | | | | | | | | | | | This fixes the segfault caused by solaris client in Gluster/NFS. Volname was not being parsed properly, Instead of volume name complete path was being used in nfs_mntpath_to_xlator(). Fixed it by striping volume name from complete path in nfs_mntpath_to_xlator(). Modified function name nfs3_funge_solaris_zerolen_fh() to nfs3_funge_webnfs_zerolen_fh() as zero-filled filehandle is specific to WebNFS. RFC : https://tools.ietf.org/html/rfc2055 Solaris uses WebNFS, the zero-filled FH is defined in the WebNFS spec. Logic was even added in fuction nfs3_funge_webnfs_zerolen_fh() to send subdir path in function glfs_resolve_at() instead of complete path for subdir mount.

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | Introduce glfs_sysrq() as a generic API for triggering debug and troubleshoot events. This interface will be used by the feature to get statedumps for applications using libgfapi. The current events that can be requested through this API are: - 'h'elp: log a mesage with all supported events - 's'tatedump: trigger a statedump for the passed glfs_t In future, this API can be used by a CLI to trigger statedumps from storage servers. At the moment it is limited to take statedumps, but it is extensible to set the log-level, clear caches, force reconnects and much more.

| | | | | | | | | | | | | | | | | | | | | | | In graph_setup function glfs_subvol_done is called which is executed in an epoll thread. glfs_lock waits on other thread to finish graph migration. 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.

* gfapi: do not cache upcalls if the application is not interestedNiels de Vos2016-08-253-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the volume option 'features.cache-invalidation' is enabled, upcall events are sent from the brick process to the client. Even if the client is not interested in upcall events itself, md-cache or other xlators may benefit from them. By adding a new 'cache_upcalls' boolean in the 'struct glfs', we can enable the caching of upcalls when the application called glfs_h_poll_upcall(). NFS-Ganesha sets up a thread for handling upcalls in the initialization phase, and calls glfs_h_poll_upcall() before any NFS-client accesses the NFS-export. In the future there will be a more flexible registration API for enabling certain kind of upcall events. Until that is available, this should work just fine. Verificatio of this change is not trivial within our current regression test framework. The bug report contains a description on how to reliably reproduce the problem with the glusterfs-coreutils.

It also sees that the previous graph B was never set as fs->active_subvol, i.e. no IO or anything happened on B, so can safely send GF_EVENT_PARENT_DOWN (by calling glfs_subvol_done(B)). This parent down on B, results in child_down(B), which is fine. But child_down also triggers graph_setup(B). - graph_setup(B) as a result of GF_EVENT_CHILD_DOWN, and fs->next_subvol = B, and GF_EVENT_PARENT_DOWN on C as explained above. This again leads to GF_EVENT_CHILD_DOWN on C. - graph_setup(C) as a result of GF_EVENT_CHILD_DOWN, and fs->next_subvol = C, and GF_EVENT_PARENT_DOWN on B as explained above. Thus both the graphs B and C are disconnected, and hence the ENOTCON Solution: Remove the call to graph_setup() when the event is GF_EVENT_CHILD_DOWN. It don't see any reason why graph_setup should be called when there is child_down. Not sure what the original reason was, to have graph_setup in child_down. git hostory shows the first patch itself had this call.

* api: use versioned symbols for minor ABI changeKaleb S KEITHLEY2016-06-144-15/+13
| | | | | | | | | | | | | | | | | | | | | | | No need to expand the API/ABI. E.g., see how glfs_lookupat changed between 3.7.0 and 3.7.4 IIRC (I originally argued against versioning the library. I wanted to just add new functions as they were needed, as was initially done for glfs_ipc and glfs_ipc_xd in the master branch for 4.0. But others strongly wanted versioning.) Having made the decision to use versioning, I believe we should continue. At least until we have a public decision that we're no longer going to use versioning.
