Package: erlang-base-hipe Version: 1:18.3-dfsg-1 Severity: important Tags: ipv6
Dear Maintainer, after upgrade to ejabberd 18.3 it won't start. I found that problem is in connection to epmd, which won't accept the connection. Run `epmd -d` in one terminal. Run `strace epmd -names` in second terminal. The second command will get stuck when connecting to the first epmd, strace says: ... socket(PF_INET6, SOCK_STREAM, IPPROTO_IP) = 3 connect(3, {sa_family=AF_INET6, sin6_port=htons(4369), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28 ... and nothing happens. After few minutes, connect times out and fails. I'm running only ejabberd 18.3, it worked fine with ejabberd 18.2 and erlang of the same age. I disabled IPv6 using `echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6` and everything works again, except IPv6 connectivity (luckily I don't have it anyway). With this workaround `strace epmd -names` says: ... socket(PF_INET6, SOCK_STREAM, IPPROTO_IP) = 3 connect(3, {sa_family=AF_INET6, sin6_port=htons(4369), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = -1 EADDRNOTAVAIL (Cannot assign requested address) close(3) = 0 socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3 connect(3, {sa_family=AF_INET, sin_port=htons(4369), sin_addr=inet_addr("127.0.0.1")}, 16) = 0 write(3, "\0\1n", 3) = 3 read(3, "\0\0\21\21", 4) = 4 fstat(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 4), ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f40ce13b000 write(1, "epmd: up and running on port 436"..., 45epmd: up and running on port 4369 with data:) = 45 read(3, "", 3060) = 0 close(3) = 0 exit_group(0) = ? +++ exited with 0 +++ So the IPv6 connect fails instantly and IPv4 connect works fine. -- System Information: Debian Release: stretch/sid APT prefers stable APT policy: (750, 'stable'), (700, 'unstable'), (650, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.5.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=cs_CZ.utf8, LC_CTYPE=cs_CZ.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) Versions of packages erlang-base-hipe depends on: ii adduser 3.114 ii init-system-helpers 1.31 ii libc6 2.22-7 ii libsystemd0 229-5 ii libtinfo5 6.0+20160319-1 ii procps 2:3.3.11-3 ii zlib1g 1:1.2.8.dfsg-2+b1 Versions of packages erlang-base-hipe recommends: ii erlang-crypto 1:18.3-dfsg-1 ii erlang-syntax-tools 1:18.3-dfsg-1 ii libsctp1 1.0.16+dfsg-3 Versions of packages erlang-base-hipe suggests: pn erlang <none> pn erlang-doc <none> ii erlang-edoc 1:18.3-dfsg-1 pn erlang-gs <none> ii erlang-manpages 1:18.3-dfsg-1 ii erlang-tools 1:18.3-dfsg-1 -- no debconf information
