On a 32 bit kernel the igb driver may cause a page

2009-11-16T18:46:33Z

fault panic due to a failed bounce page allocation during RX mbuf setup. The large demand on bounce pages is due to the alignment requirement in the tag, the ixgbe driver has demonstrated this to be unnecessary and so it is being removed here to fix this problem. Note that ultimately there needs to be a more elegant handling of the failure case here. Approved by: re

This patch addresses an overflow in the the zfs boot code and allows users to boot from zfs raidz volumes. This has been tested by a number of users and does not impact those which are not booting from zfs raidz volumes. Submitted by: Matt Reimer Approved by: re (kib)

2009-11-10T00:46:08Z

Initialize the whole message unit's DMA buffer to zero, this fixes a panic during boot when ARC1200 is being used with certain motherboard models. This commit brings the driver to the same state of vendor's 1.20.00.16 release. Many thanks to Areca for their continued support to FreeBSD.

Increase the size of the OFW translations buffer to handle G5 systems that use many translation regions in firmware, and add bounds checking to prevent buffer overflows in case even the new value is exceeded. Short MFC requested by re since the problem this fixes broken CD boot on most G5 systems, making them uninstallable.

Fix ACL support on sparc64. Turns out that fuword(9) fetches 64 bits instead of sizeof(int), and on sparc64 that resulted in fetching wrong value for acl_maxcnt, which in turn caused __acl_get_link(2) to fail with EINVAL. PR: sparc64/139304 Submitted by: Dmitry Afanasiev Approved by: re (kib)
