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.

* binarin/epmd-race: Prevent down nodes going undetected in epmd OTP-13301
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.
2011-07-13Let epmd ignore empty ERL_EPMD_ADDRESSHolger Weiß
If the environment variable ERL_EPMD_ADDRESS is set to the empty string, empd now behaves like it does by default when ERL_EPMD_ADDRESS is unset. That is, in this case, epmd now listens on all available interfaces instead of using only the loopback interface, which happened because epmd added the loopback address to the (in this case empty) list of addresses specified via ERL_EPMD_ADDRESS. Also, epmd now ignores ERL_EPMD_ADDRESS if it contains only separator characters (comma and space). The same applies to epmd's -address option.

2011-01-11check return value of epmd server listen() callSteve Vinoski
The listen() call can fail due to a variety of conditions, so check its return value and if it fails, print a suitable debug message if appropriate and then exit. The exit values used are the same for those already used for bind() failures: 0 if the error is EADDRINUSE, 1 otherwise.
2010-11-26epmd: include host address in local access checkMichael Santos
In FreeBSD jails, the source and destination address of connections to localhost are changed to be the IP address of the jail. Consider connections from the host's IP address to itself (e.g., the source and destination address match) to be local for the access control checks. Reported-By: [email protected]
2010-11-17Allow user to specify the IP address epmd binds toHolger Weiß
The IP address(es) epmd binds to can now be specified by the user, either via epmd's new "-address" option or (if that's not used) by setting the environment variable ERL_EPMD_ADDRESS. Multiple addresses may be specified using a comma-separated list. If the loopback address is not in this list, it will be added implicitly, so that the daemon can be queried by an interactive epmd process.
2010-11-13Fix epmd's dbg_perror() outputHolger Weiß
The dbg_perror() function now hands the current errno value over to dbg_gen_printf(). This fixes the problem that errno had been reset to zero by the time it was used (to print the corresponding error message) in the dbg_gen_printf() function.
