| | | | | | | | | | | | | | | | | | | | | | | | | | | While investigating gfapi memory consumption with valgrind, valgrind reported several memory access issues. Also see the timer 'registry' being recreated (shortly) after being freed during teardown due to the way it's currently written. Passing ctx as data to gf_timer_proc() is prone to memory access issues if ctx is freed before gf_timer_proc() terminates. (And in fact this does happen, at least in valgrind.) gf_timer_proc() doesn't need ctx for anything, it only needs ctx->timer, so just pass that. Nothing ever calls gf_timer_registry_init(). Nothing outside of timer.c that is. Making it and gf_timer_proc() static.

* glusterd: add defence mechanism to avoid brick port clashesPrasanna Kumar Kalever2016-05-041-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Kalever2016-05-032-2/+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 in the rhgs Env, but that's a different story on its own, which will be handled in upcoming patches.

* 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.

| | | | | | | | | | | | | | | | | | | | For an encrypted connection, sockect_connect() used to launch socket_poller() in it's own thread (ON by default), even if the connect failed. This would cause two unrefs to be done on the transport, once in socket_poller() and once in socket_connect(), causing the transport to be freed and cleaned up. This would cause further reconnect attempts from failing as the transport wouldn't be available. By starting socket_poller() only if connect succeeded, this is avoided.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Glusterd not working using ipv6 transport. The idea is with proper glusterd.vol configuration, 1. glusterd needs to listen on default port (240007) as IPv6 TCP listner. 2. Volume creation/deletion/mounting/add-bricks/delete-bricks/peer-probe needs to work using ipv6 addresses. 3. Bricks needs to listen on ipv6 addresses. All the above functionality is needed to say that glusterd supports ipv6 transport and this is broken. Fix: When "option transport.address-family inet6" option is present in glusterd.vol file, it is made sure that glusterd creates listeners using ipv6 sockets only and also the same information is saved inside brick volume files used by glusterfsd brick process when they are starting. Tests Run: Regression tests using ./run-tests.sh IPv4: Ran manually till tests/basic/rpm.t .

* all: reduce "inline" usageJeff Darcy2015-09-012-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | There are three kinds of inline functions: plain inline, extern inline, and static inline. All three have been removed from .c files, except those in "contrib" which aren't our problem. Inlines in .h files, which are overwhelmingly "static inline" already, have generally been left alone. Over time we should be able to "lower" these into .c files, but that has to be done in a case-by-case fashion requiring more manual effort. This part was easy to do automatically without (as far as I can tell) any ill effect. In the process, several pieces of dead code were flagged by the compiler, and were removed.

It seems to occur because the rpc_clnt connections are binding to ports in the same range. so brick fails to bind to a port which is already used by someone else solution: fix for now is to make rpc_clnt to get port numbers from 65535 in a descending order, as a result port clash is minimized other fixes: previously rdma binds to port >= 1024 if it cannot find a free port < 1024, even when bind insecure was turned off(ref to commit '0e3fd04e'), this patch add's a check for bind-insecure in gf_rdma_client_bind function This patch also re-enable bind-insecure and allow insecure by default which was reverted (ref: commit cef1720) previously Change-Id: Ia1cfa93c5454e2ae0ff57813689b75de282ebd07 BUG: 1238661 Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com> Reviewed-on: http://review.gluster.org/11512 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | GlusterD or a brick would crash when encrypted transport was enabled and an unencrypted client tried to connect to them. The crash occured when GlusterD/server tried to remove the transport from their xprt_list due to a DISCONNECT event. But as the client transport's list head wasn't inited, the process would crash when list_del was performed. Initing the client transports list head during acceptence, prevents this crash. Also, an extra check has been added to the GlusterD and Server notification handlers for client DISCONNECT events. The handlers will now first check if the client transport is a member of any list. GlusterD and Server DISCONNECT event handlers could be called without the ACCEPT handler, which adds the transport to the list, being called. This situation also occurs when an unencrypted client tries to establish a connection with an encrypted server.

* rpc-transport: socket_poller fixes for proper working of mgmt encryptionKaushal M2015-07-131-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | socket_poller, the polling function used by ssl own_thread, had two issues which lead to GlusterD crashes when using management encryption Issue 1 ------- socket_poller calls functions which require THIS to be set. But, THIS was being set conditionally. Because of this, functions could sometimes be called without THIS being set. For example, rpc_transport_notify could be called for an accepted client socket without THIS being set, as THIS was only set it the transport wasn't yet connected. This would cause the process to crash when THIS was accessed by the called functions. To fix this, THIS is being set at the start of socket_poller unconditionally. Issue 2 ------- DISCONNECT notify was being sent on the listener transport instead of the client transport. The DISCONNECT event was converted to a LISTENER_DEAD event in rpcsvc_handle_disconnect, as it could not find the listener socket of the listener socket. GlusterD was notified of a LISTENER_DEAD event instead of a DISCONNECT and failed to remove the client transport from its xprt_list. The transport would subsequently be freed, leaving the xprt_list with a corrupted/invalid entry. Later, when GlusterD would iterate over the xprt_list to send notifications, it would crash when the invalid entry was accessed. To fix this, DISCONNECT notification in socket_poller is sent on the client socket, as it is done in the epoll handler.

The option sets the transport.tcp-user-timeout option that is handled in the rpc/socket layer on the protocol/server side. This socket option makes detecting unclean disconnected clients more reliable. When the socket gets closed, any locks that the client held are been released. This makes it possible to reduce the fail-over time for applications that run on systems that became unreachable due to a network partition or general system error client-side (kernel panic, hang, ...). It is not trivial to create a test-case for this at the moment. We need a client that unclean disconnects and an other client that tries to take over the lock from the disconnected client.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The RPC throttle which kicks in by setting the poll-in event on a socket to false, is broken with the MT epoll commit. This is due to the event handler of poll-in attempting to read as much out of the socket till it receives an EAGAIN. Which may never happen and hence we would be processing far more RPCs that we want to. This is being fixed by changing the epoll from ET to LT, and reading request by request, so that we honor the throttle. The downside is that we do not drain the socket, but go back to epoll_wait before reading the next request, but when kicking in throttle, we need to anyway and so a busy connection would degrade to LT anyway to maintain the throttle. As a result this change should not cause deviation in the performance much for busy connections.
