* stack: Make sure to have unique call-stacks in all casesPranith Kumar K2019-05-301-3/+0
| | | | | | | | | | | | | | | At the moment new stack doesn't populate frame->root->unique in all cases. This makes it difficult to debug hung frames by examining successive state dumps. Fuse and server xlators populate it whenever they can, but other xlators won't be able to assign 'unique' when they need to create a new frame/stack because they don't know what 'unique' fuse/server xlators already used. What we need is for unique to be correct. If a stack with same unique is present in successive statedumps, that means the same operation is still in progress. This makes 'finding hung frames' part of debugging hung frames easier. fixes bz#1714098 Change-Id: I3e9a8f6b4111e260106c48a2ac3a41ef29361b9e Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>

* protocol: remove compound fopAmar Tumballi2019-04-299-7483/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | Compound fops are kept on wire as a backward compatibility with older AFR modules. The AFR module used beyond 4.x releases are not using compound fops. Hence removing the compound fop in the protocol code. Note that, compound-fops was already an 'option' in AFR, and completely removed since 4.1.x releases. So, point to note is, with this change, we have 2 ways to upgrade when clients of 3.x series are present. i) set 'use-compound-fops' option to 'false' on any volume which is of replica type. And then upgrade the servers. ii) Do a two step upgrade. First from current version (which will already be EOL if it's using compound) to a 4.1..6.x version, and then an upgrade to 7.x. Consider the overall code which we are removing for the option seems quite high, I believe it is worth it. updates: bz#1693692 Signed-off-by: Amar Tumballi <amarts@redhat.com> Change-Id: I0a8876d0367a15e1410ec845f251d5d3097ee593

* client/fini: return fini after rpc cleanupMohammed Rafi KC2019-04-112-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | There is a race condition in rpc_transport later and client fini. Sequence of events to happen the race condition 1) When we want to destroy a graph, we send a parent down event first 2) Once parent down received on a client xlator, we will initiates a rpc disconnect 3) This will in turn generates a child down event. 4) When we process child down, we first do fini for Every xlator 5) On successful return of fini, we delete the graph Here after the step 5, there is a chance that the fini on client might not be finished. Because an rpc_tranpsort ref can race with the above sequence. So we have to wait till all rpc's are successfully freed before returning the fini from client Change-Id: I20145662d71fb837e448a4d3210d1fcb2855f2d4 fixes: bz#1659708 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>
* protocol: add an option to force using old-protocolAmar Tumballi2019-04-103-3/+24
| | | | | | | | | | | | | | As protocol implements every fop, and in general a large part of the codebase. Considering our regression is run mostly in 1 machine, there was no way of forcing the client to use old protocol (while new one is available). With this patch, a new 'testing' option is provided which forces client to use old protocol if found. This should help increase the code coverage by at least 10k lines overall. updates: bz#1693692 Change-Id: Ie45256f7dea250671b689c72b4b6f25037cef948 Signed-off-by: Amar Tumballi <amarts@redhat.com>
* mgmt/shd: Implement multiplexing in self heal daemonMohammed Rafi KC2019-04-011-1/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Shd daemon is per node, which means they create a graph with all volumes on it. While this is a great for utilizing resources, it is so good in terms of performance and managebility. Because self-heal daemons doesn't have capability to automatically reconfigure their graphs. So each time when any configurations changes happens to the volumes(replicate/disperse), we need to restart shd to bring the changes into the graph. Because of this all on going heal for all other volumes has to be stopped in the middle, and need to restart all over again. Solution: This changes makes shd as a per volume daemon, so that the graph will be generated for each volumes. When we want to start/reconfigure shd for a volume, we first search for an existing shd running on the node, if there is none, we will start a new process. If already a daemon is running for shd, then we will simply detach a graph for a volume and reatach the updated graph for the volume. This won't touch any of the on going operations for any other volumes on the shd daemon. Example of an shd graph when it is per volume graph ----------------------- | debug-iostat | ----------------------- / | \ / | \ --------- --------- ---------- | AFR-1 | | AFR-2 | | AFR-3 | -------- --------- ---------- A running shd daemon with 3 volumes will be like--> graph ----------------------- | debug-iostat | ----------------------- / | \ / | \ ------------ ------------ ------------ | volume-1 | | volume-2 | | volume-3 | ------------ ------------ ------------ Change-Id: Idcb2698be3eeb95beaac47125565c93370afbd99 fixes: bz#1659708 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>
* protocol/client: Do not fallback to anon-fd if fd is not openPranith Kumar K2019-03-311-1/+7
| | | | | | | | | | | | | | | | | | If an open comes on a file when a brick is down and after the brick comes up, a fop comes on the fd, client xlator would still wind the fop on anon-fd leading to wrong behavior of the fops in some cases. Example: If lk fop is issued on the fd just after the brick is up in the scenario above, lk fop will be sent on anon-fd instead of failing it on that client xlator. This lock will never be freed upon close of the fd as flush on anon-fd is invalid and is not wound below server xlator. As a fix, failing the fop unless the fd has FALLBACK_TO_ANON_FD flag.

* client-rpc: Fix the payload being sent on the wirePoornima G2019-03-296-244/+308
| | | | | | | | | | | | | | | | | | | The fops allocate 3 kind of payload(buffer) in the client xlator: - fop payload, this is the buffer allocated by the write and put fop - rsphdr paylod, this is the buffer required by the reply cbk of some fops like lookup, readdir. - rsp_paylod, this is the buffer required by the reply cbk of fops like readv etc. Currently, in the lookup and readdir fop the rsphdr is sent as payload, hence the allocated rsphdr buffer is also sent on the wire, increasing the bandwidth consumption on the wire. With this patch, the issue is fixed. Fixes: bz#1692093 Change-Id: Ie8158921f4db319e60ad5f52d851fa5c9d4a269b Signed-off-by: Poornima G <pgurusid@redhat.com>

* core: heketi-cli is throwing error "target is busy"Mohit Agrawal2019-01-311-2/+2
| | | | | | | | | | | | | | | | | | | | Problem: When rpc-transport-disconnect happens, server_connection_cleanup_flush_cbk() is supposed to call rpc_transport_unref() after open-files on that transport are flushed per transport.But open-fd-count is maintained in bound_xl->fd_count, which can be incremented/decremented cumulatively in server_connection_cleanup() by all transport disconnect paths. So instead of rpc_transport_unref() happening per transport, it ends up doing it only once after all the files on all the transports for the brick are flushed leading to rpc-leaks.

* copy_file_range support in GlusterFSRaghavendra Bhat2018-12-1212-7/+464
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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>

So, no regression should be observed from any of the existing glusterfs deployment, supported or unsupported.

* server: don't allow '/' in basenameAmar Tumballi2018-11-051-4/+17
| | | | | | | | | | | | | | | | Server stack needs to have all the sort of validation, assuming clients can be compromized. It is possible for a compromized client to send basenames with paths with '/', and with that create files without permission on server. By sanitizing the basename, and not allowing anything other than actual directory as the parent for any entry creation, we can mitigate the effects of clients not able to exploit the server.

Considering this was not done on brick processes, we have no easy way to glance and understand which fops were pending. What gets changed: After a crash, most of the core-dumps logged were of the form: ``` pending frames: frame : type(0) op(18) frame : type(0) op(18) frame : type(0) op(28) ``` would change to ``` pending frames: frame : type(1) op(SETXATTR) frame : type(1) op(SETXATTR) frame : type(1) op(READDIR) ``` updates: bz#1639599 Change-Id: I0e3d2a8dee9cfde7ed0112a948f5213f546efb80 Signed-off-by: Amar Tumballi <amarts@redhat.com>

* build: cleanup xlator link, --no-undefined, libuuidv6devKaleb S. KEITHLEY2018-09-122-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While attempting to build a (pre-)5.0 of glusterfs on Ubuntu bionic and cosmic, it became apparent that there are some gremlins hiding in the combination of the xlator export-symbols, the newish addition of -Wl,--no-undefined, and the new switch to libuuid from the old contrib/uuid. Note: even though Fedora 28 (and later) and Ubuntu bionic (and later) have the same nominal version of libtool, the Fedora version appears to do a better job of recursing through dependencies to determine the libraries to link with. Examination of the build logs showed that despite appearing to work on Fedora, not all xlators and shared libs were linked with -Wl, --no-undefined, and -luuid. And in the case of the gnfs xlator, it was not only not linked with -Wl,--no-undefined but alsos not linked with -lgfxdr and -lgfrpc. Added GF_XLATOR_LDFLAGS, similar to GF_XLATOR_DEFAULT_LDFLAGS. GF_XLATOR_DEFAULT_LDFLAGS is for xlators that export/expose the default or common set of symbols. GF_XLATOR_LDFLAGS is for those remaining xlators that export/expose non-default symbols, e.g. dht and glupy. This removes the need in the future to add things like $(UUID_LIBS) to every xlator's Makefile.am. Just add it to GF_XLATOR_LDFLAGS and GF_XLATOR_DEFAULT_LDFLAGS in configure.ac and you're done. This patch was tested on Fedora 28 (build, rpmbuild), Fedora Rawhide/30 (rpmbuild), RHEL8 (rpmbuild), CentOS7 (rpmbuild), Fedora koji --scratch build for f30/rawhide, and a Launchpad build for Ubuntu cosmic/18.10.
