patches for easier mirroring, to eliminate a special copy, to make www.freebsd.org/security a full copy of security.freebsd.org and be eventually be the same. For now files are just sitting there. The symlinks are missing. Discussed on: www (repository location) Discussed with: simon (so)

For general information regarding FreeBSD Errata Notices and Security
|
|
Advisories, including descriptions of the fields above, security
|
|
branches, and the following sections, please visit
|
|
<URL:http://security.freebsd.org/>.
|
|
|
|
I. Background
|
|
|
|
bce(4) is a network device driver for Broadcom NetXtreme II
|
|
(BCM5706/5708/5709/5716) PCI/PCIe Gigabit Ethernet adapters. The
|
|
lagg(4) driver is a pseudo network interface driver which allows
|
|
aggregation of multiple network interfaces as one virtual interface
|
|
for the purpose of providing fault-tolerance and high-speed links.
|
|
|
|
II. Problem Description
|
|
|
|
The bce(4) driver used an incorrect total packet length calculation. This
|
|
bug was accidentally added just after 7.1-RELEASE.
|
|
|
|
III. Impact
|
|
|
|
When adding a bce(4) interface on the system as a lagg(4) member with
|
|
the LACP aggregation protocol enabled network communication via the
|
|
bce(4) interface stops completely. Although the bce(4) interface
|
|
works if it is not a lagg(4) member, the incoming traffic statistics
|
|
which can be found in netstat(1) output will be incorrect because
|
|
every packet is recognized as full-sized one.
|
|
|
|
IV. Workaround
|
|
|
|
No workaround is available.
|
|
|
|
V. Solution
|
|
|
|
Perform one of the following:
|
|
|
|
1) Upgrade your vulnerable system to 7-STABLE or to the RELENG_7_2
|
|
security branch dated after the correction date.
|
|
|
|
2) To patch your present system:
|
|
|
|
The following patches have been verified to apply to FreeBSD 7.2 system.
|
|
|
|
a) Download the relevant patch from the location below, and verify the
|
|
detached PGP signature using your PGP utility.
|
|
|
|
# fetch http://security.FreeBSD.org/patches/EN-09:02/bce.patch
|
|
# fetch http://security.FreeBSD.org/patches/EN-09:02/bce.patch.asc
|
|
|
|
b) Apply the patch.
|
|
|
|
# cd /usr/src
|
|
# patch < /path/to/patch
|
|
|
|
c) Recompile your kernel as described in
|
|
<URL:http://www.freebsd.org/handbook/kernelconfig.html> and reboot

|
the system.
