No reconnection is initiated because reconnection is rpc-lib layer's responsibility and its flags indicate that connection is connected.

| * cluster/afr: CLI for granular entry heal enablement/disablementKrutika Dhananjay2016-11-291-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/15747 When there are already existing non-granular indices created that are yet to be healed, if granular-entry-heal option is toggled from 'off' to 'on', AFR self-heal whenever it kicks in, will try to look for granular indices in 'entry-changes'. Because of the absence of name indices, granular entry healing logic will fail to heal these directories, and worse yet unset pending extended attributes with the assumption that are no entries that need heal. To get around this, a new CLI is introduced which will invoke glfsheal program to figure whether at the time an attempt is made to enable granular entry heal, there are pending heals on the volume OR there are one or more bricks that are down. If either of them is true, the command will be failed with the appropriate error.

Namely: 1. Don't mark a child down if there's no better alternative (and you'd no longer satisfy min/max replicas); fixes unneccessary flapping. 2. If a child goes down and this causes us to fall below max_replicas, swap in a warm child immediately if it is within our halo latency (don't wait around for the next "ping"); swaps in a new child immediately helping with resiliency. 3. If the child latency is within the halo, and it's currently marked up, mark it down if it's the highest latency child and the number of children is > max_replicas; this will allow us to support the SHD use-case where we can "beam" a single copy to a geo and have it replicate within the geo after that. - More commenting Test Plan: - Run halo prove tests - Pointed compiled code at gfsglobal.prn2, tested out an NFS daemon and FUSE mounts to ensure they worked as expected on a large scale cluster.

This replies on using multiple local IP addresses, one for each server. Since IPV6 provides only ::1 as a local address, as opposed to IPv4's complete 127.x.x.x subnet, this cannot work in a pure IPv6 environment. However, FB systems do at least have enough IPv4 stack to talk locally, so fix launch_cluster to work properly when default transport is IPv6. To do this: 1) explicitly set transport.address-family volume option to inet in launch_cluster(). 2) teach glusterd to honor transport.address-family when connecting to peer glusterds in glusterd_friend_rpc_create(). Previously transport.address-family was used only for binding local socket, not for communicating with peers.

* | Halo Replication feature for AFR translatorRichard Wareing2016-12-153-11/+50

Clients can also write synchronously to the cluster simply by specifying a halo-latency which is very large (e.g. 10seconds) which will include all bricks. In other words, it allows clients to decide at mount time if they desire synchronous or asynchronous IO into a cluster and the cluster can support both of these modes to any number of clients simultaneously. There are a few new volume options due to this feature: halo-shd-latency: The threshold below which self-heal daemons will consider children (bricks) connected. halo-nfsd-latency: The threshold below which NFS daemons will consider children (bricks) connected. halo-latency: The threshold below which all other clients will consider children (bricks) connected. halo-min-replicas: The minimum number of replicas which are to be enforced regardless of latency specified in the above 3 options. If the number of children falls below this threshold the next best (chosen by latency) shall be swapped in. New FUSE mount options: halo-latency & halo-min-replicas: As descripted above. This feature combined with multi-threaded SHD support (D1271745) results in some pretty cool geo-replication possibilities. Operational Notes: - Global consistency is gaurenteed for synchronous clients, this is provided by the existing entry-locking mechanism. - Asynchronous clients on the other hand and merely consistent to their region. Writes & deletes will be protected via entry-locks as usual preventing concurrent writes into files which are undergoing replication. Read operations on the other hand should never block. - Writes are allowed from _any_ region and propagated from the origin to all other regions. The take away from this is care should be taken to ensure multiple writers do not write the same files resulting in a gfid split-brain which will require resolution via split-brain policies (majority, mtime & size). Recommended method for preventing this is using the nfs-auth feature to define which region for each share has RW permissions, tiers not in the origin region should have RO perms. TODO: - Synchronous clients (including the SHD) should choose clients from their own region as preferred sources for reads. Most of the plumbing is in place for this via the child_latency array. - Better GFID split brain handling & better dent type split brain handling (i.e. create a trash can and move the offending files into it). - Tagging in addition to latency as a means of defining which children you wish to synchronously write to Test Plan: - The usual suspects, clang, gcc w/ address sanitizer & valgrind - Prove tests Reviewers: jackl, dph, cjh, meyering Reviewed By: meyering Subscribers: ethanr Differential Revision: https://phabricator.fb.com/D1272053 Tasks: 4117827 Change-Id: I694a9ab429722da538da171ec528406e77b5e6d1 Signed-off-by: Kevin Vigor <kvigor@fb.com> Reviewed-on: http://review.gluster.org/16099 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shreyas Siravara <sshreyas@fb.com>

* glusterd/quota: upgrade quota.conf file during an upgradeManikandan Selvaganesh2016-11-081-0/+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. > Reviewed-on: http://review.gluster.org/15352 > Tested-by: Atin Mukherjee <amukherj@redhat.com> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Atin Mukherjee <amukherj@redhat.com> (cherry picked from commit 4b2cff614462508eef529c5d128e0974720e3f50) Change-Id: Idb5ba29d3e1ea0e45c85d87c952c75da9e0f99f0 BUG: 1392716 Signed-off-by: Manikandan Selvaganesh <mselvaga@redhat.com> Reviewed-on: http://review.gluster.org/15791 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Manikandan Selvaganesh <manikandancs333@gmail.com> Tested-by: Manikandan Selvaganesh <manikandancs333@gmail.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>

* socket: pollerr event shouldn't trigger socket_connnect_finishAtin Mukherjee2016-09-302-1/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Vos2016-09-202-3/+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. > Change-Id: I2116bec0e294df4046d168d8bcbba011284cd0b2 > BUG: 1377097 > Signed-off-by: Niels de Vos <ndevos@redhat.com> > Reviewed-on: http://review.gluster.org/15524 > 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> (cherry picked from commit e9b39527d5dcfba95c4c52a522c8ce1f4512ac21) Change-Id: I2116bec0e294df4046d168d8bcbba011284cd0b2 BUG: 1377290 Signed-off-by: Niels de Vos <ndevos@redhat.com> Reviewed-on: http://review.gluster.org/15528 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>

Freeing up rpc_clnt object might lead to crashes. 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: 1359364 Signed-off-by: Kotresh HR <khiremat@redhat.com> (cherry picked from commit 637ce9e2e27e9f598a4a6c5a04cd339efaa62076) Reviewed-on: http://review.gluster.org/14994 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intro: Currently glusterd maintain the portmap registry which contains ports that are free to use between 49152 - 65535, this registry is initialized once, and updated accordingly as an then when glusterd sees they are been used. Glusterd first checks for a port within the portmap registry and gets a FREE port marked in it, then checks if that port is currently free using a connect() function then passes it to brick process which have to bind on it. Problem: We see that there is a time gap between glusterd checking the port with connect() and brick process actually binding on it. In this time gap it could be so possible that any process would have occupied this port because of which brick will fail to bind and exit. Case 1: To avoid the gluster client process occupying the port supplied by glusterd : we have separated the client port map range with brick port map range more @ http://review.gluster.org/#/c/13998/ Case 2: (Handled by this patch) To avoid the other foreign process occupying the port supplied by glusterd : To handle above situation this patch implements a mechanism to return EADDRINUSE error code to glusterd, upon which a new port is allocated and try to restart the brick process with the newly allocated port. Note: Incase of glusterd restarts i.e. runner_run_nowait() there is no way to handle Case 2, becuase runner_run_nowait() will not wait to get the return/exit code of the executed command (brick process). Hence as of now in such case, we cannot know with what error the brick has failed to connect. This patch also fix the runner_end() to perform some cleanup w.r.t return values.

* rpc: define client port rangePrasanna Kumar Kalever2016-05-102-2/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: when bind-insecure is 'off', all the clients bind to secure ports, if incase all the secure ports exhaust the client will no more bind to secure ports and tries gets a random port which is obviously insecure. we have seen the client obtaining a port number in the range 49152-65535 which are actually reserved as part of glusterd's pmap_registry for bricks, hence this will lead to port clashes between client and brick processes. Solution: If we can define different port ranges for clients incase where secure ports exhaust, we can avoid the maximum port clashes with in gluster processes. Still we are prone to have clashes with other non-gluster processes, but the chances being very low, but that's a different story on its own, which will be handled in upcoming patches.

* rpc: split FOPs enum from glusterfs.hNiels de Vos2016-04-288-1/+218
| | | | | | | | | | | | | | | | | | | | | | | | | | | Moving the enumeration of FOPs and some of the other parts that are defining the network protocol to the rpc/xdr/ section. These structures need some care when modifications are made, moving them out of the common glusterfs.h header helps with that. The protocol definition structures are generated in a new glusterfs-fops header. This file is present in rpc/xdr/src/ and libglusterfs/src/, it is a little ugly, but prevents the need to update all Makefile.am files with the additional -I option for finding the new header file. The generation of the .c and .h files from the .x descriptions needed small modifications to accommodate these changes. The build/xdrgen script was improved slightly for this. The .c and .h files are incorrectly in the $(top_srcdir), instead of $(top_builddir). This is an existing issue, and bug 1330604 has been filed to get that addressed.

* socket: Don't cleanup encrypted transport in socket_connect()Kaushal M2016-04-071-12/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ..instead cleanup only in socket_poller() With commit d117466 socket_poller() wasn't launched from socket_connect (for encrypted connections), if connect() failed. This was done to prevent the socket private data from being double unreffed, from the cleanups in both socket_poller() and socket_connect(). This allowed future reconnects to happen successfully. If a socket reconnects is sort of decided by the rpc notify function registered. The above change worked with glusterd, as the glusterd rpc notify function (glusterd_peer_rpc_notify()) continuously allowed reconnects on failure. mgmt_rpc_notify(), the rpc notify function in glusterfsd, behaves differently. For a DISCONNECT event, if more volfile servers are available or if more addresses are available in the dns cache, it allows reconnects. If not it terminates the program. For a CONNECT event, it attempts to do a volfile fetch rpc request. If sending this rpc fails, it immediately terminates the program. One side effect of commit d117466, was that the encrypted socket was registered with epoll, unintentionally, on a connect failure. A weird thing happens because of this. The epoll notifier notifies mgmt_rpc_notify() of a CONNECT event, instead of a DISCONNECT as expected. This causes mgmt_rpc_notify() to attempt an unsuccessful volfile fetch rpc request, and terminate. (I still don't know why the epoll raises the CONNECT event) Commit 46bd29e fixed some issues with IPv6 in GlusterFS. This caused address resolution in GlusterFS to also request of IPv6 addresses (AF_UNSPEC) instead of just IPv4. On most systems, this causes the IPv6 addresses to be returned first. GlusterD listens on 0.0.0.0:24007 by default. While this attaches to all interfaces, it only listens on IPv4 addresses. GlusterFS daemons and bricks are given 'localhost' as the volfile server. This resolves to '::1' as the first address. When using management encryption, the above reasons cause the daemon processes to fail to fetch volfiles and terminate. Solution -------- The solution to this is simple. Instead of cleaning up the encrypted socket in socket_connect(), launch socket_poller() and let it cleanup the socket instead. This prevents the unintentional registration with epoll, and socket_poller() sends the correct events to the rpc notify functions, which allows proper reconnects to happen.
