* New tools:
o ypldap(8), an YP server using LDAP as a backend.
o xcompmgr(1) was added to xenocara.
* New functionality:
o The libc resolver(3) may now be forced to perform lookups by TCP only using a new resolv.conf(5) option. The nameserver declaration in resolv.conf(5) has also been extended to allow specification of non-default nameserver ports.
o apropos(1) has two new options (-S and -s) to allow searching by machine architecture and manual section.
o aucat(1) now has audio server capability. Audio devices can be shared between multiple applications. Applications can run natively on fixed sample rate devices or on devices with unusual encodings. Multi-channel audio devices can be split into smaller independent subdevices.
o aucat(1) now has a deviceless mode, in which it can be used as a general purpose audio file format conversion utility (to mix, demultiplex, resample or reencode files).
o ifconfig(8) can now list channels supported by an IEEE 802.11 device.
o New views were added to systat(8): malloc, bucket and pool. Improvements were made to existing views.
o vnconfig(8) can now create devices with arbitrary geometry with the new -t option.
o FFS filesystems are now supported on most devices, e.g. CD's, that have sector sizes other than 512 bytes.
o Disklabels are now correctly placed and found on most devices, e.g. CD's, that have sector sizes other than 512 bytes.
* Assorted improvements and code cleanup:
o malloc(3) has gained new attack mitigation measures; critical bookkeeping structures are protected at runtime using mprotect(2) and allocated at random addresses where possible.
o A new version of the gdtoa code has been integrated, bringing better C99 support to printf(3) and friends.
o Vastly improved C99 support in libm, including complex math support.
o The sppp(4) layer and thus kernel pppoe(4) now support usernames and passwords of up to 255 characters.
o Recognize and spoof disklabel entries for more FAT and FAT32 variants.
o Automatically recognize tapes with 64K records.
o Improve option handling in dhcpd(8).
o When booting from a cd the root file system is now assumed to be on the cd, rather than always asking for the location.
o Disklabels constructed from native disklabels are now subject to the same consistancy checks as all other disklabels.
o No longer display geometry information for sd(4) disk drives, since it was mostly fictitious these days.
o Fix handling of tftp ERROR frames so OpenBSD pxeboot can be loaded from picky tftp servers.
o Many scsi(4) drivers now retry operations that can't be immediately started rather than giving up.
o MBR and DPME disklabels are no longer written out with invalid checksum information in some circumstances.
* Install/Upgrade process changes:
o crunchgen(1) and crunchide(1) have been merged into crunchgen(8), which is now built and installed by default.
o mksuncd(1) now lives in base and is installed by default.
o CD-ROM installs are now supported on SGI.
o Accept initial root passwords containing backslash characters.
o Install now allows multiple interfaces to be configured with dhcp(8).
o Upgrades now use the minimal protocols(5) and services(5) files provided on the install media.
o The install media no longer contain a disktab(5) file.
o Serial console speed is correctly determined on macppc.
* OpenSSH 5.2:
o New features:
+ Added an option to ssh(1) to force logging to syslog rather than stderr.
+ The sshd_config(5) ForceCommand directive now accepts commandline arguments for the internal-sftp server.
+ The ssh(1) ~C escape commandline now support runtime creation of dynamic port forwards.
+ Support the SOCKS4A protocol in ssh(1) dynamic forwards.
+ Support remote port forwarding with a listen port of '0'.
+ sshd(8) now supports setting PermitEmptyPasswords and AllowAgentForwarding in Match blocks.
o The following significant bugs have been fixed in this release:
+ Repair a ssh(1) crash introduced in openssh-5.1 when the client is sent a zero-length banner.
+ The eow@openssh.com and more-sessions@openssh.com[/email] protocol extensions are now only sent to peers that identify themselves as OpenSSH.
+ Avoid printing "Non-public channel" warnings in sshd(8), since ssh(1) has sent incorrect channel numbers since ~2004; make ssh(1) send the correct channel number for SSH2_MSG_CHANNEL_SUCCESS and SSH2_MSG_CHANNEL_FAILURE.
+ Avoid double-free in ssh(1) ~C escape -L handler.
+ Correct fail-on-error behaviour in sftp(1) batchmode for remote stat operations.
+ Avoid hang in ssh(1) when attempting to connect to a server that has MaxSessions set to zero.
