Package: radvd Version: 1:1.0-1 Severity: normal
Running radvd on an Alpha PWS 433au causes alignment traps with error messages appearing on both the console and in syslog. The reported address is consistent, and I was able to track down the cause. The workaround below is not a proper fix, but will serve to illustrate the problem. The trap occurs in the vicinity of line 299 in send.c:send_ra(): cmsg->cmsg_len = CMSG_LEN(sizeof(struct in6_pktinfo)); and the workaround on the Alpha is to force 8-byte alignment (sizeof(size_t), which is the size of the cmsg_len structure member) where chdr is declared near the beginning of send_ra(): /* char chdr[CMSG_SPACE(sizeof(struct in6_pktinfo))]; */ char __attribute__((aligned(8))) chdr[CMSG_SPACE(sizeof(struct in6_pktinfo))]; Note that it's possible this is really a compiler quirk of some kind, because a quick reading of the CMSG_SPACE() macro implies that some attention is being paid to possible alignment issues. Compiler version locally is gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21). -- System Information: Debian Release: 4.0 APT prefers stable APT policy: (500, 'stable') Architecture: alpha Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.24-rc5 Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US (charmap=ISO-8859-1) Versions of packages radvd depends on: ii adduser 3.102 Add and remove users and groups ii libc6.1 2.6-2 GNU C Library: Shared libraries radvd recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
