Upstream patch for this issue
Proposed upstream patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=ba0166708ef4da7eeb61dd92bbba4d5a749d6561 MRG: Patch added to -85 This was addressed via: MRG Realtime for RHEL 5 Server (RHSA-2009:0009) |
Description of problem: Wei Yongjun reported that "Since call to function sctp_sf_abort_violation() need paramter 'arg' with 'struct sctp_chunk' type, it will read the chunk type and chunk length from the chunk_hdr member of chunk. But call to sctp_sf_violation_paramlen() always with 'struct sctp_paramhdr' type's parameter, it will be passed to sctp_sf_abort_violation(). This may cause kernel panic. sctp_sf_violation_paramlen() |-- sctp_sf_abort_violation() |-- sctp_make_abort_violation() This patch fixed this problem. This patch also fix two place which called sctp_sf_violation_paramlen() with wrong paramter type."
