The following commit was made upstream: http://linux.bkbits.net:8080/linux-2.6/cset@43220081yu9ClBQNuqSSnW_9amW7iQ This was to fix a flaw that meant that a local? user could attempt a dio/mmap and cause a sg driver oops, based on this message: http://marc.theaimsgroup.com/?l=linux-scsi&m=112540053711489&w=2 This may affect RHEL4, it needs a quick sanity check.
Quick check shows it's needed. Being built/tested now.
Submitted for internal review, but I don't currently have appropriate software to test with, so inclusion may very well not happen this time around.
PM ack for U4, putting on ProposedList. Would this be a Beta Blocker?
committed in stream U4 build 36.1. A test kernel with this patch is available from http://people.redhat.com/~jbaron/rhel4/
