vm audit: add VM_DONTEXPAND to mmap for drivers that need it (CVE-2008-0007) 2008-02-08T19:46:21+00:00 Nick Piggin npiggin@suse.de 2008-02-02T02:08:53+00:00 f5871b9016c0ebce8acc58f7a230adcb9bd89577 Drivers that register a ->fault handler, but do not range-check the offset argument, must set VM_DONTEXPAND in the vm_flags in order to prevent an expanding mremap from overflowing the resource.

tty: fix logic change introduced by wait_event_interruptible_timeout() 2007-12-23T20:54:37+00:00 Cory T. Tusar ctusar@videon-central.com 2007-12-23T20:34:51+00:00 db99247ac68fc352100090ad7704fb5efb9327b6 Commit 5a52bd4a2dcb570333ce6fe2e16cd311650dbdc8 introduced a subtle logic change in tty_wait_until_sent(). The original version would only error out of the 'do { ... } while (timeout)' loop if signal_pending() evaluated to true; a timeout or break due to an empty buffer would fall out of the loop and into the tty->driver->wait_until_sent handling. The current implementation will error out on either a pending signal or an empty buffer, falling through to the tty->driver->wait_until_sent handling only on a timeout. The ->wait_until_sent() will not be reached if the buffer empties before timeout jiffies have elapsed. This behavior differs from that prior to commit 5a52bd4a2dcb570333ce6fe2e16cd311650dbdc8. I turned this up while using a little serial download utility to bootstrap an ARM-based eval board. The util worked fine on 2.6.22.x, but consistently failed on 2.6.23.x. Once I'd determined that, I narrowed things down with git bisect, and found the above difference in logic in tty_wait_until_sent() by inspection. This change reverts the logic flow in tty_wait_until_sent() to match that prior to the aforementioned commit. Signed-off-by: Cory T.
