Release notes
Stable release candidate
Most regressions in 0.99 over 0.98 are now believed to be fixed. This release should be considered a release-candidate for a new stable series, and we urge any remaining users of 0.98 to test this release and report any bugs. A blocker meta-bug exists to track critical regressions.
bgpd: Preliminary UI and Linux-IPv4 support for TCP-MD5 merged
Initial support for TCP-MD5 has been merged. This adds the neighbor ... password command, and some support for setting TCP-MD5 on pure-IPv4 connections on Linux. On Linux systems with IPv6 available, passing the -l 0.0.0.0 argument to bgpd may allow TCP-MD5 support to work. It's not possible at this point to have IPv6 sessions and also use TCP-MD5 on IPv4 sessions. This will hopefully be rectified in a future release.
bgpd: Fix double-free crash in bgp_table_finish, seen with rs-client
Though diagnosed with rs-clients, this fix very likely addresses a number of crashes reported to Quagga bugzilla.
zebra: ignore dead routes in RIB update
This fix may address some issues reported with routes not being consistent between the zebra RIB and the kernel FIB, remaining after the fixes in last release.
Solaris: Sync SMF bits with OpenSolaris SFW
The Quagga packaging support for Solaris has been updated to synchronise with OpenSolaris SFW. Of particular note is that SMF schema has been updated to match the Sun PSARC approved schema, which is supported by the OpenSolaris routeadm utility. User's may need to familiarise themselves with the changed FMRIs, and may need to update any administrative scripts.
A short-form list of more notable, code related changes:

- 2008-06-11: Quagga 0.99.10 Released
Quagga 0.99.10 has been released, and is available, along with a full changelog, in the usual places.

Release notes
zebra: Races in the RIB could lead to routes not being installed to kernel FIB
bgpd: 4-Byte AS Number support
Quagga now supports 4-byte AS numbers.
bgpd: Low impact AS4 Attribute DoS (Mu Security)
This release fixes further potential DoS conditions in bgpd, again reported by Mu Security, where a bgpd could be made to crash if an UPDATE was sent with certain AS4 attributes. The possible crashes are either a NULL pointer dereference, or an assert, and so are not thougth to be exploitable.
As AS4 support is only being introduced in this release of Quagga, the impact is considered neglible. The exception is where pre-release Quagga software, with initial AS4 support, has been deployed. Such deployments are vulnerable to a DoS initiated by any remote participant in the BGP network.
NB: The CVS commit message mistakenly says this affects only configured peers. The above advice takes precedence.
bgpd: Sundry regression fixes
Sessions would be incorrectly reset if a partial AS-Pathlimit attribute was received. All users of 0.99.9 bgpd, in which AS-Pathlimit support was introduced, that receive public routes will need to upgrade to 0.99.10 to avoid this issue.
Advertisement of Multi-Protocol prefixes (i.e. non-IPv4) had been broken in the 0.99.9 release.
BSD: Interface link-state now supported
Solaris: Support added for Solaris 10U5 IP instance privileges

[zebra] fixed bug #402: now the second zebra process doesn't destroy routes of the first one before dying [zebra] we are not going to receive routing messages originated by old_pid, because rib_sweep_route() is called after damon() now. This will allow to drop old_pid completely soon. [zebra] Switch from LOOKUP() to lookup() for rtm_type (see bug #401 for details). [zebra] * rt_socket.c: (kernel_rtm_ipv4) prefix_buf could be passed to zlog_err() uninitialized with debug disabled.
