* gfapi: warn when glfs_realpath() returned malloc'd memoryNiels de Vos2016-10-281-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: use const qualifier for glfs_*timens()Oleksandr Natalenko2016-08-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | glfs_*timens() functions have the last argument of struct timespec type that is supposed to be const. Now using glfs_*timens() in fops, implemented on top of FUSE library, leads to compiler-time warning about discarding const qualifier. Introducing const qualifier does not break ABI, so let's just fix it. > Reviewed-on: http://review.gluster.org/15119 > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > Reviewed-by: Niels de Vos <ndevos@redhat.com> BUG: 1365869 Change-Id: Iea2a1018de7dce67f67a8229671a5978246de800 Signed-off-by: Oleksandr Natalenko <oleksandr@natalenko.name> Reviewed-on: http://review.gluster.org/15137 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: Kaleb KEITHLEY <kkeithle@redhat.com> Reviewed-by: Prashanth Pai <ppai@redhat.com>

* every/where: add GF_FOP_IPC for inter-translator communicationJeff Darcy2015-03-171-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several features - e.g. encryption, erasure codes, or NSR - involve multiple cooperating translators which sometimes need a "private" means of communication amongst themselves. Historically we've used virtual or synthetic xattrs, but that's not very elegant and clutters up the getxattr/setxattr path which must also handle real xattr requests. This new fop should address that. The only argument is an int32_t "op" which should be recognized by the target translator. It is recommended that translators using these feature follow some convention regarding the ops that they define, to avoid conflicts. Using a hash of the target translator's type string as a base for a series of ops would probably be a good start. Any other information can be passed in both directions using xdata. The default behavior for this fop, as with any other, is to pass through to FIRST_CHILD. That makes use of this fop "transparent" to other translators that were written before it existed, but it also means that it only really works with pass-through translators. If a routing translator (such as DHT) or a fan-out translator (such as AFR) is involved, the IPC might not reach its intended destination unless those translators are modified to forward IPC fops along all paths. If an IPC gets all the way to storage/posix it is considered an error, much like an uncaught exception. We don't actually *do* anything in that case, but we do log it send back an EOPNOTSUPP error. This makes the "unrecognized opcode" condition distinguishable from the "no IPC support" condition (which would yield an RPC error instead) so clients can probe for the presence of a handler for their own favorite opcode and either use that or use old-school xattrs depending on the result.

* api: versioned symbols in libgfapi.so for compatibilityKaleb S. KEITHLEY2015-01-121-93/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use versioned symbols to keep libgfapi at libgfapi.so.0.0.0 Revisited to address broken build on Mac OS X See http://review.gluster.org/9036 Rebased to include http://review.gluster.org/#/c/9376/ (glfs_resolve()) but note that gerrit's "Rebase Change" couldn't do it. N.B. noticed that glfs_get_volumeid() decl in glfs.h was missing the __THROW, added it. On systems using ELF and the GNU toolchain, symbol versions are created with a .symver asm operand in the .c source file. Clang is claimed to be compatible with gcc, so we'll pretend for now that this also works with clang. On Mac OS X, aliases are created with __asm "magic" in the .h header file. In the normal case, when both the decl and defn match, that's all that's needed. In our case though the decl and defn don't match --- we have, e.g. a defn such as 'int glfs_foo(...)' and the corresponding decl is 'int pub_glfs_foo(...)'. To make this work we create the necessary aliases in the library at link time with the -alias_list link option. Note that this results in there being pairs of symbols in the .dylib, e.g. _pub_glfs_foo and _glfs_foo$GFAPI_3.4.0. We could use another link option, -unexported_symbols_list to elide the _pub_glfs_* symbols. (And we probably should.) Linux symbol versioning was essentially copied from Solaris; in general I would expect this to "just work" on Solaris, but until someone tries we don't really know.

Zerofill writes zeroes to a file in the specified range. This fop will be useful when a whole file needs to be initialized with zero (could be useful for zero filled VM disk image provisioning or during scrubbing of VM disk images). Client/application can issue this FOP for zeroing out. Gluster server will zero out required range of bytes ie server offloaded zeroing. In the absence of this fop, client/application has to repetitively issue write (zero) fop to the server, which is very inefficient method because of the overheads involved in RPC calls and acknowledgements. WRITESAME is a SCSI T10 command that takes a block of data as input and writes the same data to other blocks and this write is handled completely within the storage and hence is known as offload . Linux ,now has support for SCSI WRITESAME command which is exposed to the user in the form of BLKZEROOUT ioctl. BD Xlator can exploit BLKZEROOUT ioctl to implement this fop. Thus zeroing out operations can be completely offloaded to the storage device , making it highly efficient. The fop takes two arguments offset and size. It zeroes out 'size' number of bytes in an opened file starting from 'offset' position. This patch adds zerofill support to the following areas: - libglusterfs - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi Client applications can exloit this fop by using glfs_zerofill introduced in libgfapi.FUSE support to this fop has not been added as there is no system call for this fop. Changes from previous version 3: * Removed redundant memory failure log messages Changes from previous version 2: * Rebased and fixed build error Changes from previous version 1: * Rebased for latest master TODO : * Add zerofill support to trace xlator * Expose zerofill capability as part of gluster volume info Here is a performance comparison of server offloaded zeofill vs zeroing out using repeated writes.

* gfapi: object handle based API extensionsR.Shyamsundar2013-10-111-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is an ongoing effort to integrate NFS Ganesha ( https://github.com/nfs-ganesha/nfs-ganesha/wiki ) with GlusterFS as one of the file system back ends. Towards this we need extensions to gfapi that can handle object based operations. Meaning, instead of using full paths or relative paths from cwd, it is required that we can work with APIs, like the *at POSIX variants, to be able to create, lookup, open etc. files and directories. Hence the objects are the files or directories themselves and we give out handles to these objects that can be used for further operations. This code drop is an initial implementation of the proposed APIs. The new APIs are implemented as glfs_h_XXX variants in the file glfs-handleops.c to mirror glfs-fops.c style. The code leverages holding onto inode references and doling these out as opaque/cookie type objects to the callers, to enable them to be used as handles in other operations. An fd based approach was considered, but due to the extra footprint that the fd structure and its counterparts would incur, this was dropped to take the approach of holding inode references themselves. Tested by extending glfsxmp.c to invoke and exercise the added APIs, and further tested with a reference integration of the same as an FSAL with NFS Ganesha.

This patch adds fallocate support to the following areas: - libglusterfs - mount/fuse - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi BUG: 949242 Change-Id: Ice8e61351f9d6115c5df68768bc844abbf0ce8bd Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-on: http://review.gluster.org/4969 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
