* multiple files: another attempt to remove includesYaniv Kaul2019-06-141-5/+0
| | | | | | | | | | | | | | | | | | There are many include statements that are not needed. A previous more ambitious attempt failed because of *BSD plafrom (see https://review.gluster.org/#/c/glusterfs/+/21929/ ) Now trying a more conservative reduction. It does not solve all circular deps that we have, but it does reduce some of them. There is just too much to handle reasonably (dht-common.h includes dht-lock.h which includes dht-common.h ...), but it does reduce the overall number of lines of include we need to look at in the future to understand and fix the mess later one.

* core: avoid dynamic TLS allocation when possibleXavi Hernandez2019-04-241-241/+48
| | | | | | | | | | | | | | | | | | | Some interdependencies between logging and memory management functions make it impossible to use the logging framework before initializing memory subsystem because they both depend on Thread Local Storage allocated through pthread_key_create() during initialization. This causes a crash when we try to log something very early in the initialization phase. To prevent this, several dynamically allocated TLS structures have been replaced by static TLS reserved at compile time using '__thread' keyword. This also reduces the number of error sources, making initialization simpler.

* copy_file_range support in GlusterFSRaghavendra Bhat2018-12-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * libglusterfs changes to add new fop * Fuse changes: - Changes in fuse bridge xlator to receive and send responses * posix changes to perform the op on the backend filesystem * protocol and rpc changes for sending and receiving the fop * gfapi changes for performing the fop * tools: glfs-copy-file-range tool for testing copy_file_range fop - Although, copy_file_range support has been added to the upstream fuse kernel module, no release has been made yet of a kernel which contains the support. It is expected to come in the upcoming release of linux-4.20 So, as of now, executing copy_file_range fop on a fused based filesystem results in fuse kernel module sending read on the source fd and write on the destination fd. Therefore a small gfapi based tool has been written to be able test the copy_file_range fop. This tool is similar (in functionality) to the example program given in copy_file_range man page. So, running regular copy_file_range on a fuse mount point and running gfapi based glfs-copy-file-range tool gives some idea about how fast, the copy_file_range (or reflink) can be. On the local machine this was the result obtained. mount -t glusterfs workstation:new /mnt/glusterfs [root@workstation ~]# cd /mnt/glusterfs/ [root@workstation glusterfs]# ls file [root@workstation glusterfs]# cd [root@workstation ~]# time /tmp/a.out /mnt/glusterfs/file /mnt/glusterfs/new real 0m6.495s user 0m0.000s sys 0m1.439s [root@workstation ~]# time glfs-copy-file-range $(hostname) new /tmp/glfs.log /file /rrr OPEN_SRC: opening /file is success OPEN_DST: opening /rrr is success FSTAT_SRC: fstat on /rrr is success copy_file_range successful real 0m0.309s user 0m0.039s sys 0m0.017s This tool needs following arguments 1) hostname 2) volume name 3) log file path 4) source file path (relative to the gluster volume root) 5) destination file path (relative to the gluster volume root) "glfs-copy-file-range <hostname> <volume> <log file path> <source> <destination>" - Added a testcase as well to run glfs-copy-file-range tool * io-stats changes to capture the fop for profiling * NOTE: - Added conditional check to see whether the copy_file_range syscall is available or not. If not, then return ENOSYS. - Added conditional check for kernel minor version in fuse_kernel.h and fuse-bridge while referring to copy_file_range. And the kernel minor version is kept as it is. i.e. 24. Increment it in future when there is a kernel release which contains the support for copy_file_range fop in fuse kernel module. * The document which contains a writeup on this enhancement can be found at https://docs.google.com/document/d/1BSILbXr_knynNwxSyyu503JoTz5QFM_4suNIh2WwrSc/edit Change-Id: I280069c814dd21ce6ec3be00a884fc24ab692367 updates: #536 Signed-off-by: Raghavendra Bhat <raghavendra@redhat.com>
* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* libglusterfs: Add put fopPoornima G2017-12-051-0/+2
| | | | | | | | | | | | | | | | | Problem: It had been a longtime request to implement put fop in gluster. put fop in gluster may not have the exact sementics of HTTP PUT, but can be easily extended to do so. The subsequent patches, will contain more semantics on the put fop and its guarentees. Why compound fop framework is not used for put? Compound fop framework currently doesn't allow compounding of entry fop and inode fops, i.e. fops on multiple inodes cannot be combined in compound fop.

* libglusterfs: the global_xlator should have valid cbksNiels de Vos2017-07-271-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a case where Gluster/NFS needs to resolve a path outside of the nfs-xlator itself. While resolving the path to fetch the GFID for creating the NFS-filehandle, gfapi may set an inode-ctx through glfs_resolve_at(). This inode-ctx is linked with the global_xlator. Because the global_xlator does not have any cbks, loc_wipe() will cause a segfault when it calls inode_unref() and xl->cbks->forget(). It is assumed that all xlators have a cbks symbol, otherwise loading of the xlator will fail. The global_xlator is not loaded in the same way, so there is no failure noticed when the instance is created. By adding an empty `struct xlator_cbks`, the global_xlator behaves similat to other xlators that do not implement all callbacks. I would have preferred to keep the inode-ctx setting through glfs_resolve_at() contained within Gluster/NFS. Unfortunately Gluster/NFS also uses the inode-ctx, and is not prepared to see the values that glfs_resolve_at() stores there. This problem is not easily reproducible because it involves mounting over WebNFS (like Solaris 10 can do). The segfault will also not be immediate, unless the following is done: 1. create a subdir on a volume 2. mount the volume/subdir over WebNFS 3. unmount the volume/subdir 4. mount the root of the volume 5. delete the subdir on the volume -> segfault of Gluster/NFS Change-Id: I2bd71d033e97edc07ba93b2d4ada558f65d68999 BUG: 1468291 Signed-off-by: Niels de Vos <ndevos@redhat.com> Reviewed-on: https://review.gluster.org/17897 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Amar Tumballi <amarts@redhat.com> Reviewed-by: jiffin tony Thottan <jthottan@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Jeff Darcy <jeff@pl.atyp.us>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch, there will be additional entries seen in the profile info: UPCALL : Total number of upcall events that were sent from the brick(in brick profile), and number of upcall notifications recieved by client(in client profile) Cache invalidation events: ------------------------- CI_IATT : Number of upcalls that were cache invalidation and had one of the IATT_UPDATE_FLAGS set. This indicates that one of the iatt value was changed. CI_XATTR : Number of upcalls that were cache invalidation, and had one of the UP_XATTR or UP_XATTR_RM set. This indicates that an xattr was updated or deleted. CI_RENAME : Number of upcalls that were cache invalidation, resulted by the renaming of a file or directory CI_UNLINK : Number of upcalls that were cache invalidation, resulted by the unlink of a file. CI_FORGET : Number of upcalls that were cache invalidation, resulted by the forget of inode on the server side.

This is because, each cache invalidation can carry multiple flags. Eg: - Every CI_XATTR will have CI_IATT - Every CI_UNLINK will also increment CI_IATT as link count is an iatt attribute. Also UP_PARENT_DENTRY_FLAGS is currently not accounted for, as CI_RENAME and CI_UNLINK will always have the flag UP_PARENT_DENTRY_FLAGS Change-Id: Ieb8cd21dde2c4c7618f12d025a5e5156f9cc0fe9 BUG: 1371543 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/15193 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Rajesh Joseph <rjoseph@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>

* every/where: add GF_FOP_IPC for inter-translator communicationJeff Darcy2015-03-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* glusterfs: zerofill supportM. Mohan Kumar2013-11-101-0/+1

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.Shyamsundar2013-10-111-1/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Therefore __glusterfs_this_location called gf_log which used THIS which wraps __glusterfs_this_location which . . . you get the idea. We have to break the loop somewhere, and we can't reasonably make _gf_log stop using THIS, so we make __glusterfs_this_location stop using _gf_log.

| | | | | | | | | | | | | | | | Add support for the DISCARD file operation. Discard punches a hole in a file in the provided range. Block de-allocation is implemented via fallocate() (as requested via fuse and passed on to the brick fs) but a separate fop is created within gluster to emphasize the fact that discard changes file data (the discarded region is replaced with zeroes) and must invalidate caches where appropriate.

* glusterfs_ctx_t: un-globalize the filesystem contextAnand Avati2012-07-171-45/+0
| | | | | | | | | | | | | | | | | | | | | | | | So far there has been a global glusterfs_ctx_t object which represents the running instance of the filesystem (client or server). It contains the various graphs, connection to the management daemon over which new graphs are obtained, calls stacks issued on this filesystem, and a bunch of such things. With the introduction of libgfapi, it is no more true that there will be only one filesystem context in a process. Applications can be written to use libgfapi and obtain serveral instances of different filesystems/volumes in the same process. This involves messy untangling of assumptions inside libglusterfs that there would only be one global glusterfs_ctx_t and offload that assumption to glusterfsd/ and cli/ (where it is true).
