Package: linux-2.6 Version: 2.6.26-13lenny2 Severity: critical Note - this bug affects upstream 2.6.29 as well, but I believe the Debian 2.6.28 packages are ok (the mips-specific changes for CVE-2009-0029 happened later).
----- Forwarded message from dann frazier <da...@dannf.org> ----- Date: Mon, 23 Mar 2009 21:01:32 -0600 From: dann frazier <da...@dannf.org> To: linux-m...@linux-mips.org Subject: syscall wrapper changes cause llseek failure hey, I had a report today of a possible regression caused by the syscall wrapper changes. On a pristine 64-bit 2.6.29-rc8 kernel, llseek seems to always return -EINVAL. This was noticed on one of the Debian infrastructure machines where, after an upgrade, e2fsck began failing with errors like: Error reading block 524290 (Invalid argument) while getting next inode from scan. Ignore error<y>? I believe this is due to the syswrapper changes because its easy to reproduce with Debian's 2.6.26 patched w/ the syswrapper changes, but goes away if we back the syswrapper changes back out. I compared strace output between a working and failing kernel: no syscall wrappers: _llseek(3, 2147491840, [2147491840], SEEK_SET) = 0 _llseek(3, 2147524608, [2147524608], SEEK_SET) = 0 syscall wrappers: _llseek(3, 2147491840, 0x7fa5d7f0, SEEK_SET) = -1 EINVAL (Invalid argument) _llseek(3, 2147491840, 0x7fa5d6d0, SEEK_SET) = -1 EINVAL (Invalid argument) config is available here; http://dannf.org/mips.config -- dann frazier ----- End forwarded message ----- -- dann frazier -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
