Skips any sockets with unsupported protocols.
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'
