2016-03-29Don't send unasked for systemd notificationsAlexey Lebedeff
Suppose we have some erlang system that uses systemd unit with Type=notify - so this should send startup confirmation itself. But if systemd-enabled epmd will be started as a first step of that system startup, empd startup confirmation will be misinterpeted by systemd. And our erlang service will be considered 'ready' to early. Also this will interefere with systemd MAINPID detection: systemd will be monitoring `epmd` process instead of `beam` one. For example, rabbitmq works around this issue by starting epmd using separate short-lived beam process, with NOTIFY_SOCKET environment variable reset - only in this way we could be sure that epmd will not interfere with rabbit startup sequence. This patch disables indiscriminate confirmation sending, and does it only when it was explicitly asked to do so.

2016-03-02Skips any sockets with unsupported protocols.Ingela Anderton Andin
Patch from end of PR 864 Fixes problem reported in the PR by jeckersb In this error case, a negative file descriptor is now saved at listensock[i], which leads to a buffer overflow later on at https://github.com/msantos/otp/blob/epmd-IPv6-node-reg2/erts/epmd/src/epmd_srv.c#L498 when calling FD_ISSET(listensock[i],&read_mask). To reproduce this: Completely disable IPv6 with ipv6.disable=1 on the kernel command line Build with fortified code (RHEL/CentOS default): CFLAGS='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fno-strict-aliasing'

2016-02-10epmd: support IPv6 node registrationMichael Santos
Allow IPv6 nodes to register with and query epmd. On systems with IPv6 support: * epmd listens on both the IPv4 and IPv6 ANY or loopback sockets * the epmd cli client connects to epmd over the IPv6 loopback * distributed nodes started with "-proto_dist inet6_tcp" will register with epmd over IPv6 To work on IPv6 capable systems that have IPv6 support disabled, epmd ignores errors opening the socket if the protocol is not supported. Similarly, the epmd client will fall back to IPv4 if the IPv6 socket is not available. Update the minimum supported version of Windows to Windows Vista to support IPv6.

2015-12-28Merge branch 'maint'Zandra
2015-12-15Prevent down nodes going undetected in epmdAlexey Lebedeff
In the following (rare) case down node will be always registered in epmd: - client connects to epmd and sends ALIVE2 request - epmd reads this request and starts to process it - during that time client socket closes in such way that subsequent write(2) in epmd will result in error - at this point we have node that was registered in database, but as the connection struct has no 'keep' flag set, the do_read() closes connection and removes it from select fdset - and so there is no way for this node to be cleaned up later. We've seen several epmd instances in such state on our production systems. And while I'm not sure what was the exact sequence of events that leads to failed write(2), issue could be easily reproduced using SO_LINGER option for socket.
2015-12-14Don't wait for twice the delay_write timeoutAlexey Lebedeff
This happens only during processing ALIVE2 request. reply() already performs the same delay as in the deleted code.

2014-01-14epmd: Fix -names option on WindowsJohannes Weißl
Since 3aa60cc `epmd -names` does not produce any output on Windows anymore. This patch uses fwrite() instead of write() which adds the necessary carriage returns to the output so that it is suitable for the Windows cmd.exe. A test case is added (fails on Windows without the patch).
2013-09-11Fix syslog definesMatt Lewandowsky
config.h defines HAVE_SYSLOG_H whereas the sources are looking for NO_SYSLOG to be undefined. As the logic of "if feature is available" makes more sense than "if feature is not unavailable", I opted for the config.h define.

2011-07-27Fix epmd crash on vxworks caused by faulty argument to selectSverker Eriksson
The first argument g->max_conn to select() in epmd_srv.c seems to be wrong as it excludes the listening socket(s). Instead we keep track of the highest fd seen. However I still don't understand why select() started to fail for vxworks with R14B03 when the feature of more than one listening socket was introduced. The default is still 1 listening socket (num_sockets=1), which would make the first argument to select() unchanged.
