* Use int instead of int8_t for the 3 variablesMichael Scherer2017-02-281-1/+1
| | | | | | | | | | | | | | | | | | | | | Since strcmp return a int, and since the spec of strcmp do not tell the return value, it could return 256 and this would overflow. Found by Coverity scan.

* rpcsvc: Add rpchdr and proghdr to iobref before submitting to transportPoornima G2017-02-152-3/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: When fio is run on multiple clients (each client writes to its own files), and meanwhile the clients does a readdirp, thus the client which did a readdirp will now recieve the upcalls. In this scenario the client disconnects with rpc decode failed error. RCA: Upcall calls rpcsvc_request_submit to submit the request to socket: rpcsvc_request_submit currently: rpcsvc_request_submit () { iobuf = iobuf_new iov = iobuf->ptr fill iobuf to contain xdrised upcall content - proghdr rpcsvc_callback_submit (..iov..) ... if (iobuf) iobuf_unref (iobuf) } rpcsvc_callback_submit (... iov...) { ... iobuf = iobuf_new iov1 = iobuf->ptr fill iobuf to contain xdrised rpc header - rpchdr msg.rpchdr = iov1 msg.proghdr = iov ... rpc_transport_submit_request (msg) ... if (iobuf) iobuf_unref (iobuf) } rpcsvc_callback_submit assumes that once rpc_transport_submit_request() returns the msg is written on to socket and thus the buffers(rpchdr, proghdr) can be freed, which is not the case. In especially high workload, rpc_transport_submit_request() may not be able to write to socket immediately and hence adds it to its own queue and returns as successful. Thus, we have use after free, for rpchdr and proghdr. Hence the clients gets garbage rpchdr and proghdr and thus fails to decode the rpc, resulting in disconnect. To prevent this, we need to add the rpchdr and proghdr to a iobref and send it in msg: iobref_add (iobref, iobufs) msg.iobref = iobref; The socket layer takes a ref on msg.iobref, if it cannot write to socket and is adding to the queue. Thus we do not have use after free.

* socket: retry connect immediately if it failsJeff Darcy2017-02-021-2/+36
| | | | | | | | | | | | | | | | | | | | | | Previously we relied on a complex dance of setting flags, shutting down the socket, tearing stuff down, getting an event, tearing more stuff down, and waiting for a higher-level retry. What we really need, in the case where we're just trying to connect prematurely e.g. to a brick that hasn't fully come up yet, is a simple retry of the connect(2) call. This was discovered by observing failures in ec-new-entry.t with multiplexing enabled, but probably fixes other random failures as well.

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-303-3/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this, we will be able to trigger statedumps on remote Gluster clients, mainly targetted for applications using libgfapi. Design: SIGUSR signal is the most comman way of taking a statedump in Gluster. But it cannot be used for libgfapi based processes, as the process loading the library might have already consumed SIGUSR signal. Hence going by the command way. One has to issue a Gluster command to initiate a statedump on the libgfapi based client. The command takes hostname and PID as an argument. All the glusterds in the cluster, check if they are connected to the specified hostname, and send an RPC request to all the connected clients from that hostname (via the mgmt connection).

The commands affected: 1) Attach tier will trigger this process instead of old one 2) tier start and tier start force will also trigger this process. 3) volume status [tier] will show tier daemon as a process instead of task and normal tier status and tier detach status works. 4) tier stop implemented. 5) detach tier implemented separately along with new detach tier status 6) volume tier volname status will work using the changes. 7) volume set works This patch has separated the tier translator from the legacy DHT rebalance code. It now sends the RPCs from the CLI to glusterd separate to the DHT rebalance code. The daemon is now a service, similar to the snapshot daemon, and can be viewed using the volume status command. The code for the validation and commit phase are the same as the earlier tier validation code in DHT rebalance. The “brickop” phase has been changed so that the status command can use this framework. The service management framework is now used. DHT rebalance does not use this framework. This service framework takes care of : *) spawning the daemon, killing it and other such processes. *) volume set options , which are written on the volfile. *) restart and reconfigure functions. Restart is to restart the daemon at two points 1)after gluster goes down and comes up. 2) to stop detach tier. *) reconfigure is used to make immediate volfile changes. By doing this, we don’t restart the daemon. it has the code to rewrite the volfile for topological changes too (which comes into place during add and remove brick). With this patch the log, pid, and volfile are separated and put into respective directories.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently these are few events related to child_up/down: GF_EVENT_CHILD_UP : Issued when any of the protocol client connects. GF_EVENT_CHILD_MODIFIED : Issued by afr/dht/ec GF_EVENT_CHILD_DOWN : Issued when any of the protocol client disconnects. These events get modified at the dht/afr/ec layers. Here is a brief on the same. DHT: - All the subvolumes reported once, and atleast one child came up, then GF_EVENT_CHILD_UP is issued - connect GF_EVENT_CHILD_UP is issued - disconnect GF_EVENT_CHILD_MODIFIED is issued - All the subvolumes disconnected, GF_EVENT_CHILD_DOWN is issued AFR: - First subvolume came up, then GF_EVENT_CHILD_UP is issued - Subsequent subvolumes coming up, results in GF_EVENT_CHILD_MODIFIED - Any of the subvolumes go down, then GF_EVENT_SOME_CHILD_DOWN is issued - Last up subvolume goes down, then GF_EVENT_CHILD_DOWN is issued Until the patch [1] introduced GF_EVENT_SOME_CHILD_UP, GF_EVENT_CHILD_MODIFIED was issued by afr/dht when any of the subvolumes go up or down. Now with md-cache changes, there is a necessity to differentiate between child up and down. Hence, introducing GF_EVENT_SOME_DESCENDENT_DOWN/UP and getting rid of GF_EVENT_CHILD_MODIFIED.

* glusterd/quota: upgrade quota.conf file during an upgradeManikandan Selvaganesh2016-11-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem ======= When quota is enabled on 3.6, it will have quota conf version in quota.conf as v1.1. This node gets upgraded to 3.7 but it will still have quota conf version as v1.1 until a quota enable/disable/set limit is initiated. When this is not initiated and when this node tries to peer probe a node which is a fresh install of 3.7 (which will have quota conf version as v1.2), then this will result in "Peer rejected" state. This patch fixes the issue. Solution ======== When an upgrade happens from 3.6 to 3.7, quota.conf file needs to be modified as well. With 3.6, in quota.conf the version will be v1.1 and it needs to be changed to v1.2 from 3.7. This is because in 3.7, inode quota feature is introduced. So when an op-version bumpup happens quota.conf needs to be upgraded with quota conf version v1.2 and all the 16 byte uuid needs to be changed to 17 bytes uuid as well. Previously, when the cluster version is upgraded to 3.7, the quota.conf got upgraded as well. But, the upgradation was done only when quota enable/disable/set limit is done. With this patch, the upgradation is done during a cluster op version bump up as well.

* rpc: Fix the race between notification and reconnectionPranith Kumar K2016-10-241-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: There was a hang because unlock on an entry failed with ENOTCONN. Client thinks the connection is down where as server thinks the connection is up. This is the race we are seeing: 1) Connection from client to the brick disconnects. 2) Saved frames unwind is called which unwinds all frames that were wound before disconnect. 3) connection from client to the brick happens and setvolume. 4) Disconnect notification for the connection in 1) comes now and calls client_rpc_notify() which marks the connection to be offline even when the connection is up. This is happening because I/O can retrigger connection before disconnect notification is sent to the higher layers in rpc. Fix: Notify the higher layers that a disconnect happened and then go ahead with reconnect logic.

* compound fops: Fix file corruption issueKrutika Dhananjay2016-10-244-15/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Address of a local variable @args is copied into state->req in server3_3_compound (). But even after the function has gone out of scope, in server_compound_resume () this pointer is accessed and dereferenced. This patch fixes that. 2. Compound fops, by virtue of NOT having a vector sizer (like the one writev has), ends up having both the header and the data (in case one of its member fops is WRITEV) in the same hdr_iobuf. This buffer was not being preserved through the lifetime of the compound fop, causing it to be overwritten by a parallel write fop, even when the writev associated with the currently executing compound fop is yet to hit the desk, thereby corrupting the file's data. This is fixed by associating the hdr_iobuf with the iobref so its memory remains valid through the lifetime of the fop. 3. Also fixed a use-after-free bug in protocol/client in compound fops cbk, missed by Linux but caught by NetBSD. Finally, big thanks to Pranith Kumar K and Raghavendra Gowdappa for their help in debugging this file corruption issue.

| | | | | | | | | | | | | | | | | | | | | | | | If connect fails with any other error than EINPROGRESS we cannot get the error status using getsockopt (... SO_ERROR ... ). Hence we need to remember the state of connect and take appropriate action in the event_handler for the same. As an added note, a event can come where poll_err is HUP and we have poll_in as well (i.e some status was written to the socket), so for such cases we need to finish the connect, process the data and then the poll_err as is the case in the current code.

* rpc: increase RPC/XID with each callbackNiels de Vos2016-09-192-3/+19
| | | | | | | | | | | | | | | | | | | | | The RPC/XID for callbacks has been hardcoded to GF_UNIVERSAL_ANSWER. In Wireshark these RPC-calls are marked as "RPC retransmissions" because of the repeating RPC/XID. This is most confusing when verifying the callbacks that the upcall framework sends. There is no way to see the difference between real retransmissions and new callbacks. This change was verified by create and removal of files through different Gluster clients. The RPC/XID is increased on a per connection (or client) base. The expectations of the RPC protocol are met this way.

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>

* glusterd : Introduce reset brickAnuradha Talur2016-08-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command basically allows replace brick with src and dst bricks as same. Usage: gluster v reset-brick <volname> <hostname:brick-path> start This command kills the brick to be reset. Once this command is run, admin can do other manual operations that they need to do, like configuring some options for the brick. Once this is done, resetting the brick can be continued with the following options. gluster v reset-brick <vname> <hostname:brick> <hostname:brick> commit {force} Does the job of resetting the brick. 'force' option should be used when the brick already contains volinfo id. Problem: On doing a disk-replacement of a brick in a replicate volume the following 2 scenarios may occur : a) there is a chance that reads are served from this replaced-disk brick, which leads to empty reads. b) potential data loss if next writes succeed only on replaced brick, and heal is done to other bricks from this one. Solution: After disk-replacement, make sure that reset-brick command is run for that brick so that pending markers are set for the brick and it is not chosen as source for reads and heal. But, as of now replace-brick for the same brick-path is not allowed. In order to fix the above mentioned problem, same brick-path replace-brick is needed. With this patch reset-brick commit {force} will be allowed even when source and destination <hostname:brickpath> are identical as long as 1) destination brick is not alive 2) source and destination brick have the same brick uuid and path. Also, the destination brick after replace-brick will use the same port as the source brick.

* changelog/rpc: Fix rpc_clnt_t mem leaksKotresh HR2016-07-222-6/+99

Well, it was not a necessity to free rpc-clnt object till now because all the existing use cases needs to reconnect back on disconnects. Hence timer code was not taking ref on rpc-clnt object. Glusterd had some use-cases that led to crash due to ping-timer and they fixed only those code paths that involve ping-timer. Now, since changelog has an use-case where rpc-clnt need to be freed up, we need to fix timer code to take refs 2. In changelog, because of issue 1, only mydata was being freed which is incorrect. And there are races where rpc-clnt object would access the freed mydata which would lead to crashes. Since changelog xlator resides on brick side and is long living process, if multiple libgfchangelog consumers register to changelog and disconnect/reconnect mulitple times, it would result in leak of 'rpc-clnt' object for every connect/disconnect. SOLUTION: 1. Handle ref/unref of 'rpc_clnt' structure in timer functions properly. 2. In changelog, unref 'rpc_clnt' in RPC_CLNT_DISCONNECT after disabling timers and free mydata on RPC_CLNT_DESTROY. RPC SETUP IN CHANGELOG: 1. changelog xlator initiates rpc server say 'changelog_rpc_server' 2. libgfchangelog initiates one rpc server say 'libgfchangelog_rpc_server' 3. libgfchangelog initiates rpc client and connects to 'changelog_rpc_server' 4. In return changelog_rpc_server initiates a rpc client and connects back to 'libgfchangelog_rpc_server' REF/UNREF HANDLING IN TIMER FUNCTIONS: Let's say rpc clnt refcount = 1 1. Take the ref before reigstering callback to timer queue >>>> rpc_clnt_ref (say ref count becomes = 2) 2. Register a callback to timer say 'callback1' 3. If register fails: >>>> rpc_clnt_unref (ref count = 1) 4. On timer expiration, 'callback1' gets called. So unref rpc clnt at the end in 'callback1'. This is corresponding to ref taken in step 1 >>>> rpc_clnt_unref (ref count = 1) 5. The cycle from step-1 to step-4 continues....until timer cancel event happens 6. timer cancel of say 'callback1' If timer cancel fails: Do nothing, Step-4 would have unrefd If timer cancel succeeds: >>>> rpc_clnt_unref (ref count = 1) Change-Id: I91389bc511b8b1a17824941970ee8d2c29a74a09 BUG: 1316178 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: http://review.gluster.org/13658 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: Raghavendra G <rgowdapp@redhat.com>
