[20130613] The vtnet(4) network interface driver displays the following message upon configuration when using QEMU 1.4.1 and later:

vtnet0: error setting host MAC filter table

This message is harmless when the interface has only one MAC address. The patch for this issue is filed to a PR kern/178955.

[20130609] There is incompatibility in jail(8) configuration because the jail(8) utility and rc.d/jail script has been changed. More specifically, the following sysctl(8) variables cannot be used to set the default parameters for jails:

security.jail.mount_zfs_allowed
security.jail.mount_procfs_allowed
security.jail.mount_nullfs_allowed
security.jail.mount_devfs_allowed
security.jail.mount_allowed
security.jail.chflags_allowed
security.jail.allow_raw_sockets
security.jail.sysvipc_allowed
security.jail.socket_unixiproute_only
security.jail.set_hostname_allowed

These could be set by manually using sysctl(8) utility, the sysctl.conf(5) file, or for some of them the following variables in rc.conf(5):

jail_set_hostname_allow="yes"
jail_socket_unixiproute_only="yes"
jail_sysvipc_allow="yes"

These parameters must now be specified in jail_parameters (or jail_jailname_parameters for per-jail configuration) in rc.conf(5). For example:

jail_parameters="allow.sysvipc allow.raw_sockets"

The valid keywords are the following. For more detail, see jail(8) manual page.

allow.set_hostname
allow.sysvipc
allow.raw_sockets
allow.chflags
allow.mount
allow.mount.devfs
allow.mount.nullfs
allow.mount.procfs
allow.mount.zfs
allow.quotas
allow.socket_af

[20130608] FreeBSD 8.4-RELEASE no longer supports FreeBSD CVS repository. Some documents mistakenly refer to RELENG_8_4_0_RELEASE as CVS tag for the release and RELENG_8_4 as CVS branch tag for the 8.4-RELEASE security branch. However, FreeBSD Project no longer supports FreeBSD CVS repository and 8.4-RELEASE has been released by using FreeBSD subversion repository instead. RELENG_8_4 corresponds to svn://svn.FreeBSD.org/base/releng/8.4, and RELENG_8_4_0_RELEASE corresponds to svn://svn.FreeBSD.org/base/release/8.4.0. Please note that FreeBSD source tree for 8.4-RELEASE and its security branch cannot be updated by using official CVSup servers.

[20130607] (removed about a bge(4) network interface driver issue because it was incorrect)

[20130606] The fxp(4) network interface driver may not work well with the dhclient(8) utility. More specifically, if the /etc/rc.conf has the following line:

ifconfig_fxp0="DHCP"

to activate a DHCP client to configure the network interface, the following notification messages are displayed and the dhclient(8) utility keeps trying to initialize the network interface forever.

kernel: fxp0: link state changed to UP
kernel: fxp0: link state changed to DOWN

A patch to fix this issue will be released as an Errata Notice.
