| emporarily connected so that the kernel moves data without userland intervention. This will be used by relayd(8) in the next release. Added AES-GCM support for IPsec. Added automatic send and receive buffer scaling for TCP. Added wpakey option to ifconfig(8) replacing wpa-psk(8). TCP acknowledgments are no longer delayed on the loopback interface. Network livelock counters are now exported via sysctl(3). A radix tree sorting bug was fixed, which results in significant improvements to IPsec performance under certain conditions. tcpdump(8) now decodes Multicast DNS (mDNS) traffic. Wake on Lan support has been added to arp(8). Enabled MPLS and mpe(4) by default on GENERIC kernels. Added a mpls option to ifconfig(8) to enable MPLS on a per interface basis replacing the global sysctl knob. OpenBGPD, OpenOSPFD and other routing daemon improvements: bgpd(8) handles various message encoding errors more gracefully now. Notification messages are now logged in bgpd(8). ospfd(8) will now correctly redistribute overlapping routes. ospfctl(8) now prints the LSDB checksum in the show summary output for quick verification that two LSDBs are in sync. Fixed ldpd(8)''s message parser to work on all architectures and more LDP messages are now implemented. Various improvements in ospf6d(8). pf(4) improvements: The logging subsystem has been largely rewritten, now logging the translated addresses again instead of the original ones. match log rules cause a log on the fly, showing the packet exactly as pf(4) sees it at the moment of evaluating that rule. A packet can also be logged more than once now. match log(matches) rules allow the further rule matching to be traced. pflog(4) now includes the original addresses and ports for packets that have been rewritten. This is also displayed by tcpdump(8). IPsec stack audit was performed, resulting in: Several potential security problems have been identified and fixed. ARC4 based PRNG code was audited and revamped. New explicit_bzero kernel function was introduced to prevent a compiler from optimizing bzero calls away. SCSI improvements: Improved safety when detaching SCSI devices by waiting for the completion of pending commands. Improved hotplug support on mpi(4) and mpii(4). Continued iopoolification of SCSI drivers, notably on umass(4) which improves the reliability and performance of multi-LUN devices. Added vscsi(4), a driver for userland handling of SCSI device commands. Added iscsid(8), an iSCSI initiator. Forcibly restrict devices incapable of tagged I/O to executing one command at a time. Discover and honour read-only status of sd(4) devices. Improve st(4) handling of I/O residual information. sd(4) devices that can only execute one command at a time (e.g. USB) will now be allowed to spin up if necessary. cd(4) will now attach CDROM devices identified as non-removable. Assorted improvements: Enabled wide character support in ncurses(3). Added nsd(8), an authoritative name |
