* Events: Socket creation after getaddrinfo and IPv4 and IPv6 packet capturesrijan-sivakumar2020-08-191-8/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: Currently, the socket creation is done prior to getaddrinfo function being invoked. This can cause mismatch in the protocol and address families of the created socket and the result of the getaddrinfo api. Also, the glustereventsd UDP server by default only captures IPv4 packets hence IPv6 packets are not even captured. Code Changes: 1. Modified the socket creation in such a way that the parameters taken in are dependent upon the result of the getaddrinfo function. 2. Created a subclass for adding address family in glustereventsd.py for both AF_INET and AF_INET6. 3. Modified addresses in the eventsapiconf.py.in Reasoning behind the approach: 1. If we are using getaddrinfo function then socket creation should happen only after we check if we received back valid addresses. Hence socket creation should come after the call to getaddrinfo 2. The listening server which pushes the events to the webhook has to listen for both IPv4 and IPv6 messages as we would not be sure as to what address family is picked in _gf_event.

* events: fix IPv6 memory corruptionXavi Hernandez2020-01-171-41/+15
| | | | | | | | | | | | | When an event was generated and the target host was resolved to an IPv6 address, there was a memory overflow when that address was copied to a fixed IPv4 structure (IPv6 addresses are longer than IPv4 ones). This fix correctly handles IPv4 and IPv6 addresses returned by getaddrinfo() Change-Id: I5864a0c6e6f1b405bd85988529570140cf23b250 Fixes: bz#1790870 Signed-off-by: Xavi Hernandez <xhernandez@redhat.com>
* gf-event: Handle unix volfile-serversPranith Kumar K2019-10-301-1/+10
| | | | | | | | | | | | | | | Problem: glfsheal program uses unix-socket-based volfile server. volfile server will be the path to socket in this case. gf_event expects this to be hostname in all cases. So getaddrinfo will fail on the unix-socket path, events won't be sent in this case. Fix: In case of unix sockets, default to localhost fixes: bz#1765017 Change-Id: I60d27608792c29d83fb82beb5fde5ef4754bece8 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>

| | | | | | | | | | | | server.sin_family was set to AF_INET while creating socket connection, this was failing if the input address is IPv6(`::1`). With this patch, sin_family is set by reading the ai_family of `getaddrinfo` result.

* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* eventsapi: Add support for Client side EventsAravinda VK2016-08-301-28/+62
| | | | | | | | | | | | | | | | | | | | | | | | | Client side gf_event uses ctx->cmd_args.volfile_server to push notifications to the eventsd. Socket server changed from Unix domain socket to UDP to support external events. Following to be addressed in different patch - Port used for eventsd is 24009. Make it configurable Already configurable in Server side. Configurable in gf_event API is required. - Auth Token yet to be added as discussed in https://www.gluster.org/pipermail/gluster-devel/2016-August/050324.html Change-Id: I159acf80b681d10b82d52cfb3ffdf85cb896542d BUG: 1367774 Signed-off-by: Aravinda VK <avishwan@redhat.com> Reviewed-on: http://review.gluster.org/15189 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Prashanth Pai <ppai@redhat.com> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>
* eventsapi: Fix disable-events issueAravinda VK2016-08-241-3/+6
| | | | | | | | | | | | | | | | | | | | | | | Events related sources are not loaded in libglusterfs when configure is run with --disable-events option. Due to this every call of gf_event should be guarded with USE_EVENTS macro. To prevent this, USE_EVENTS macro was included in events.c itself(Patch #15054) Instead of disabling building entire directory "events", selectively disabled the code. So that constants and empty function gf_event is exposed. Code will not fail even if gf_event is called when events is disabled.

* eventsapi: Gluster Eventing Feature implementationAravinda VK2016-07-181-0/+83
[Depends on http://review.gluster.org/14627] Design is available in `glusterfs-specs`, A change from the design is support of webhook instead of Websockets as discussed in the design http://review.gluster.org/13115 Since Websocket support depends on REST APIs, I will add Websocket support once REST APIs patch gets merged Usage: Run following command to start/stop Eventsapi server in all Peers, which will collect the notifications from any Gluster daemon and emits to configured client. gluster-eventsapi start|stop|restart|reload Status of running services can be checked using, gluster-eventsapi status Events listener is a HTTP(S) server which listens to events emited by the Gluster. Create a HTTP Server to listen on POST and register that URL using, gluster-eventsapi webhook-add <URL> [--bearer-token <TOKEN>] For example, if HTTP Server running in `http://192.168.122.188:9000` then add that URL using, gluster-eventsapi webhook-add http://192.168.122.188:9000 If it expects a Token then specify it using `--bearer-token` or `-t` We can also test Webhook if all peer nodes can send message or not using, gluster-eventsapi webhook-test <URL> [--bearer-token <TOKEN>] Configurations can be viewed/updated using, gluster-eventsapi config-get [--name] gluster-eventsapi config-set <NAME> <VALUE> gluster-eventsapi config-reset <NAME|all> If any one peer node was down during config-set/reset or webhook modifications, Run sync command from good node when a peer node comes back. Automatic update is not yet implemented. gluster-eventsapi sync Basic Events Client(HTTP Server) is included with the code, Start running the client with required port and start listening to the events. /usr/share/glusterfs/scripts/eventsdash.py --port 8080 Default port is 9000, if no port is specified, once it started running then configure gluster-eventsapi to send events to that client. Eventsapi Client can be outside of the Cluster, it can be run event on Windows. But only requirement is the client URL should be accessible by all peer nodes.(Or ngrok(https://ngrok.com) like tools can be used) Events implemented with this patch, - Volume Create - Volume Start - Volume Stop - Volume Delete - Peer Attach - Peer Detach It is easy to add/support more events, since it touches Gluster cmd code and to avoid merge conflicts I will add support for more events once this patch merges.
