Package: tftpd-hpa Version: 5.0-5 Severity: normal Hi,
I've recently upgraded tftpd-hpa, which stopped working. In my daemon.log, I see: cannot open IPv6 socket, disable IPv6: Address family not supported by protocol Cannot set nonblock flag on socket: Bad file descriptor suspecting that these are related, I had a look at the source. It turns out that the code has support of continuing without ipv6 if the ipv6 fails but ipv4 is opened succesfully, but it even does some stuff with the ipv6 socket, even when it failed to open, resulting in this error and the daemon quitting. In tftpd.c, around line 536, I see: if (ai_fam != AF_INET) { fd6 = socket(AF_INET6, SOCK_DGRAM, 0); if (fd6 < 0) { if (fd4 < 0) { syslog(LOG_ERR, "cannot open IPv6 socket: %m"); exit(EX_OSERR); } else { syslog(LOG_ERR, "cannot open IPv6 socket, disable IPv6: %m"); } } #ifndef __CYGWIN__ set_socket_nonblock(fd6, 1); #endif memset(&bindaddr6, 0, sizeof bindaddr6); bindaddr6.sin6_family = AF_INET6; bindaddr6.sin6_port = htons(IPPORT_TFTP); } It would make sense to move the last four lines into an else of the second if (fd6 < 0). Perhaps other changes are required as well, I did not test this. The reason that the ipv6 socket fails to open is that I'm running a custom kernel with ipv6 disabled, I expect this issue will not bite users that run a stock Debian kernel, so I'm not giving this bug increased severity.
