Source: dnsmasq Severity: minor Tags: upstream ipv6 Dear Maintainer,
When dumping the dnsmasq cache by sending SIGUSR1 (with -q or -d set in options), the address portion of the cache is printed using %-30.30s at line 1457 of cache.c 30 characters is not enough for an IPv6 address - you need 39 characters in the maximal case. Actually it's 45 in the most pathological case of v6-encoded v4 addresses where the last 2 groups of 4 hex digits are replaced by a dotted-quad, but you can probably choose not to display addresses like that. The INET6_ADDRSTRLEN constant in <netinet/in.h> is 46 for this reason. I suggest that reducing the name portion from 40 to 30 (cache.c:1414) and increasing the address portion to 40 (line 1457) will suffice. -- System Information: Debian Release: jessie/sid APT prefers testing-updates APT policy: (500, 'testing-updates'), (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 3.16.1 (SMP w/4 CPU cores; PREEMPT) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
