January 13th, 2012· The FreeBSD kernel now supports Capsicum Capability Mode. Capsicum is a set of features for sandboxing support, using a capability model in which the capabilities are file descriptors. Two new kernel options CAPABILITIES and CAPABILITY_MODE have been added to the GENERIC kernel. For more information about Capsicum, see http://www.cl.cam.ac.uk/research/security/capsicum/.[r219129]
· The hhook(9) (Helper Hook) and khelp(9) (Kernel Helpers) KPIs have been implemented. These are a kind of superset of pfil(9) framework for more general use in the kernel. The hhook(9) KPI provides a way for kernel subsystems to export hook points that khelp(9) modules can hook to provide enhanced or new functionality to the kernel. The khelp(9) KPI provides a framework for managing khelp(9) modules, which indirectly use the hhook(9) KPI to register their hook functions with hook points of interest within the kernel. These allow a structured way to dynamically extend the kernel at runtime in an ABI preserving manner.[r216758, r216615]
· A new resource accounting API has been implemented. It can keep per-process, per-jail, and per-loginclass resource accounting information. Note that this is not built nor installed by default. To build and install them, specify options RACCT in the kernel configuration file and rebuild the base system as described in the FreeBSD Handbook.[r220137]
· A new resource-limiting API has been implemented. It works in conjunction with the RACCT resource accounting implementation and takes user-configurable actions based on the set of rules it maintains and the current resource usage. The rctl(8) utility has been added to manage the rules in userland. Note that this is not built nor installed by default. To build and install them, specify options RCTL in the kernel configuration file and rebuild the base system as described in the FreeBSD Handbook.[r220163]
· [powerpc] FreeBSD/powerpc now supports Sony Playstation 3 using the OtherOS feature available on firmwares 3.15 and earlier.[r217044]
· [amd64, i386] The FreeBSD usb(4) subsystem now supports USB 3.0 by default.[r223098]
· The FreeBSD usb(4) subsystem now supports USB packet filter. This allows to capture packets which go through each USB host controller. The implementation is almost based on bpf(4) code. The userland program usbdump(8) has been added.[r215649]
· A bxe(4) driver for Broadcom NetXtreme II 10GbE controllers (BCM57710, BCM57711, BCM57711E) has been added.[r219647]
· A cxgbe(4) driver for Chelsio T4 (Terminator 4) based 10Gb/1Gb adapters has been added.[r218794]
· The em(4) driver has been updated to version 7.3.2.[r219753]
· The igb(4) driver has been updated to version 2.2.5.[r223350]
· The igb(4) driver now supports Intel I350 PCIe Gigabit Ethernet controllers.[r218530]
· The ixgbe(4) driver has been updated to version 2.3.8.[r217593]
· The re(4) driver now supports RTL8168E/8111E-VL PCIe Gigabit Ethernet controllers and RTL8401E PCIe Fast Ethernet controllers.[r217498, r218760]
· A vte(4) driver for RDC R6040 Fast Ethernet controllers, which are commonly found on the Vortex86 System On a Chip, has been added.[r216829]
· A vxge(4) driver for the Neterion X3100 10GbE Server/Storage adapter has been added.[r221167]
· ipfw(8) now supports IPv6 in the fwd action.[r225044]
· ipfw(8) now supports the call and return actions. Upon the call number action, the current rule number is saved in the internal stack and ruleset processing continues with the first rule numbered number or higher. The return action takes the rule number saved to internal stack by the latest call action and returns ruleset processing to the first rule with number greater than that saved number.[r223666]
· For Infiniband support, OFED (OpenFabrics Enterprise Distribution) version 1.5.3 has been imported into the base system. Note that this is not built nor installed by default. To build and install them, specify WITH_OFED=yes in /etc/src.conf and rebuild the base system as described in the FreeBSD Handbook.[r219820]
· The FreeBSD TCP/IP network stack now supports IPv4 prefixes with /31 as described in RFC 3021, “Using 31-Bit Prefixes on IPv4 Point-to-Point Links”.[r226572]
· The FreeBSD TCP/IP network stack now supports the mod_cc(9) pluggable congestion control framework. This allows TCP congestion control algorithms to be implemented as dynamically loadable kernel modules. The following kernel modules are available as of 9.0-RELEASE: cc_chd(4) for the CAIA-Hamilton-Delay algorithm, cc_cubic(4) for the CUBIC algorithm, cc_hd(4) for the Hamilton-Delay algorithm, cc_htcp(4) for the H-TCP algorithm, cc_newreno(4) for the NewReno algorithm, and cc_vegas(4) for the Vegas algorithm. The default algorithm can be set by a new sysctl(8) variable net.inet.tcp.cc.algorithm. The value must be set to one of the names listed by net.inet.tcp.cc.available, and newreno is the default set at boot time. For more detail, see the mod_cc(4) and mod_cc(9) manual pages.[r216109, r216114, r216115, r218152, r218153, r218155]
· An h_ertt(4) (Enhanced Round Trip Time) khelp(9) module has been added. This module allows per-connection, low noise estimates of the instantaneous RTT in the TCP/IP network stack with a robust implementation even in the face of delayed acknowledgments and/or TSO (TCP Segmentation Offload) being in use for a connection.[r217806]
· A new tcp(4) socket option TCP_CONGESTION has been added. This allows to select or query the congestion control algorithm that the TCP/IP network stack will use for connections on the socket.[r218912]
· The ng_netflow(4) netgraph(4) node now supports NetFlow version 9. A new export9 hook has been added for NetFlow v9 data. Note that data export can be done simultaneously in both version 5 and version 9.[r219183]
· The geom_map(4) GEOM class has been added. This allows to generate multiple geom providers based on a hard-coded layout of a device with no explicit partition table such as embedded flash storage. For more information, see the geom_map(4) manual page.[r220559]
· The graid(8) GEOM class has been added. This is a replacement of the ataraid(4) driver supporting various BIOS-based software RAID.[r219974]
· A tws(4) driver for 3ware 9750 SATA+SAS 6Gb/s RAID controllers has been added.[r226115]
· The FreeBSD Fast File System now supports softupdates journaling. It introduces a intent log into a softupdates-enabled file system which eliminates the need for background fsck(8) even on unclean shutdown. This can be enabled in a per-filesystem basis by using the -j flag of the newfs(8) utility or the -j enable option of the tunefs(8) utility. Note that the 9.0-RELEASE installer automatically enables softupdates journaling for newly-created UFS file systems.[r207141, r218726]
· The FreeBSD Fast File System now supports the TRIM command when freeing data blocks. A new flag -t in the newfs(8) and tunefs(8) utilities sets the TRIM-enable flag for a file system. The TRIM-enable flag makes the file system send a delete request to the underlying device for each freed block. The TRIM command is specified as a Data Set Management Command in the ATA8-ACS2 standard to carry the information related to deleted data blocks to a device, especially for a SSD (Solid-State Drive) for optimization.[r216796]
· The FreeBSD NFS subsystem has been updated. The new implementation supports NFS version 4 in addition to 2 and 3. The kernel options for the NFS server and client are changed from NFSSERVER and NFSCLIENT to NFSD and NFSCL. sysctl(8) variables which start with vfs.nfssrv. have been renamed to vfs.nfsd.. The NFS server now supports vfs.nfsd.server_max_nfsvers and vfs.nfsd.server_min_nfsvers sysctl(8) variables to specify the maximum and the minimum NFS version number which the server accepts. The default value is set to 3 and 2, respectively.[r221124]
· The FreeBSD ZFS subsystem has been updated to the SPA (Storage Pool Allocator, also known as zpool) version 28. It now supports data deduplication, triple parity RAIDZ (raidz3), snapshot holds, log device removal, zfs diff, zpool split, zpool import -F, and read-only zpool import.[r219089]
· An implementation of iconv() API libraries and utilities which are standardized in Single UNIX Specification has been imported. These are based on NetBSD's Citrus implementation. Note that these are not built nor installed by default. To build and install them, specify WITH_ICONV=yes in /etc/src.conf and rebuild the base system as described in the FreeBSD Handbook.[r219019]
· A readline(3) API set has been imported into libedit. This is based on NetBSD's implementation and BSD licensed utilities now use it instead of GNU libreadline.[r220370]
· The rtsold(8) and rtadvd(8) daemons now support the RDNSS and DNSSL options described in RFC 6106, “IPv6 Router Advertisement Options for DNS Configuration”. A rtadvctl(8) utility to control the rtadvd(8) daemon has been added.[r222732, r224006]
· The rtld(1) runtime linker now supports shared objects as filters in ELF shared libraries. Both standard and auxiliary filtering have been supported. The rtld(1) linker's processing of a filter defers loading a filtee until a filter symbol is referenced unless the LD_LOADFLTR environment variable is defined or a -z loadfltr option was specified when the filter was created.[r216695]
· A bug in the tftpd(8) daemon has been fixed. It had an interoperability issue when transferring a large file.[r224536]
· The utmp(5) user accounting database has been replaced by utmpx(3). User accounting utilities will now use utmpx database files exclusively. The wtmpcvt(1) utility can be used to convert wtmp files to the new format, making it possible to read them using the updated utilities.[r202188]
· The zpool(8): utility now supports a zpool labelclear command. This allows to wipe the label data from a drive that is not active in a pool.[r224171]
July 24th, 2010· zfsloader added
· zpool version of ZFS subsystem updated to version 14
· NFSv4 ACL support in UFS and ZFS; support added to cp(1), find(1), getfacl(1), mv(1), and setfacl(1) utilities
· UltraSPARC IV/IV+, SPARC64 V support
· SMP support in PowerPC G5
· BIND 9.6.2-P2
· sendmail updated to 8.14.4
· OpenSSH updated to 5.4p1
· GNOME 2.30.1, KDE 4.4.5
April 18th, 2009· The first of two planned release candidates for the FreeBSD 7.2-RELEASE cycle is now available. Testing of some of the recent work would be particularly appreciated. This includes: bce(4) updated (there is a report that lagg(4) does not work after the update, fixing that may need to be done as an errata notice after the release); testing of the threading libraries; amr(4) should be fixed. A fix for the 'vm_page_insert: page already inserted' panics has been committed to RELENG_7_1 this morning so it missed the 7.2-RC1 builds. If you wind up being hit by that you can try a normal source based update to the current state of RELENG_7_1 and that problem should go away.
April 3rd, 2009· Testing of two recent changes to the system would be particularly valuable. The bce(4) network driver was updated a few days ago. And some significant work was done on the threading libraries a short time ago that is known to fix several major issues but testing to see if it introduced any regressions would be appreciated.
December 10th, 2008· FreeBSD 7.1-RC1 is now available, the first of the release candidates. There will be at least one more release candidate before the release so the release itself is likely around three weeks from now - if no new show-stoppers are uncovered during testing. In addition to general testing, we're looking for information about potential problems with the boot loader. And a late arrival that's not possible to test without the packages, sysinstall's issues with excessive disc swapping when installing large sets of packages off the CDROMs should be fixed. Testing to make sure that's working would be appreciated.
October 20th, 2008· As the next step in the release cycle for FreeBSD 7.1 builds for FreeBSD 7.1-BETA2 are now available for testing. The ISO images and FTP install trees are available on the FreeBSD mirror sites. The amd64 and i386 sets include a preliminary set of packages, not what is expected to be included with the release itself. The biggest change is that kde-lite was used this time, while the full kde3 will most likely be used for the release. If you would like to do a source-based update to 7.1-BETA2 from an already installed machine you can update your tree to RELENG_7 using normal cvsup/csup methods. The freebsd-update utility supports binary upgrades of i386 and amd64 systems running earlier FreeBSD releases.
