This is for per-CPU - caching flows as a means of accelerating L3 and L2 lookups - as well as providing stateful load balancing when ECMP - (Equal-Cost Multi-Path routing) is enabled by . - - A new capability flag LINKSTATE has - been added to struct - ifnet.if_capabilities. This indicates if the - interface can check the link state or not. The - &man.ifconfig.8; utility now shows this flag if - supported. - - A new event handler iflladdr_event - has been added. This signals that the L2 address on an - interface has changed, and lets stacked interfaces such as - &man.vlan.4; detect that their lower interface has changed - and adjust things in order to keep working. This fixes an - issue of &man.lagg.4; and &man.vlan.4; configuration. - - IPcomp (IP Payload Compression Protocol defined in RFC - 2393) protocol is now enabled by default. Note that this - requires in the kernel - configuration file and GENERIC kernel - does not include it. This functionality can be disabled by - using a sysctl variable - net.inet.ipcomp.ipcomp_enable. - - The &man.ipfw.4; subsystem including &man.dummynet.4; - has been updated to ipfw3 and various bugs - have been fixed: - - - - The major enhancement is a completely restructured - version of &man.dummynet.4;, with support for different - packet scheduling algorithms (loadable at runtime), - faster queue/pipe lookup, and a much cleaner internal - architecture and kernel/userland ABI which simplifies - future extensions. - - - - All of O(N) sequences in the firewall rule - evaluation removed from the kernel critical sections. - The worst case is now O(log N). - - - - It now supports ipfw0 pseudo - interface for logging similar to &man.pflog.4;. A sysctl - net.inet.ip.fw.verbose=0 enables logging - to ipfw0, and - net.inet.ip.fw.verbose=1 sends logging to - &man.syslog.3; as before. - - - - The me keyword in the &man.ipfw.4; - rule now matches any IPv6 addresses configured on an - interface as well as IPv4 ones. - - - - A bug that keep-alive rule did - not work for IPv6 packets has been fixed. - - - - The lookup match option has been added. - - lookup {dst-ip|src-ip|dst-port|src-port|uid|jail} N - - This searches the specified field in table - N and sets - tablearg accordingly. With - dst-ip or src-ip - the option replicates two existing options. When used - with other arguments, the option can be useful to - quickly dispatch traffic based on other fields. - - - - A bug in the &man.sysctl.8; variable - ip.fw.one_pass handling has been - fixed. A packet which comes from a pipe without being - delayed incorrectly ignored this variable. - - - - A memory alignment issue in the &man.ng.ksocket.4; and - &man.ng.ppp.4;, Netgraph node drivers have been fixed. This - fixes kernel panics due to the misalignment. - - The &man.ng.bridge.4; and &man.ng.hub.4; Netgraph node - drivers now supports a flag persistent. - It disables automatic node shutdown when the last hook gets - disconnected. The new control messages - NGM_BRIDGE_SET_PERSISTENT and - NGM_HUB_SET_PERSISTENT have been added - for the flag. - - The &man.pf.4; subsystem now supports - sloppy keyword to enable a TCP state - machine for tracking TCP connections with no sequence number - check. This feature is in the latest version of - pf. - - The &man.pfil.9; framework for packet filtering in &os; - kernel now supports separate packet filtering instances like - &man.ipfw.4; for each VIMAGE jail. - - A bug that proxy ARP entries cannot be added over - point-to-point link types has been fixed. - - The &man.tap.4; pseudo interface now reports the link - state properly by updating if_link_state - variable in the kernel. - - The &man.vlan.4; pseudo interface has been added to - GENERIC kernel. - - The &man.vlan.4; pseudo interface now supports TSO (TCP - Segmentation Offloading). The capability flag is named as - IFCAP_VLAN_HWTSO and it is separated from - IFCAP_VLAN_HWTAGGING. The &man.age.4;, - &man.alc.4;, &man.ale.4;, &man.bce.4;, &man.bge.4;, - &man.cxgb.4;, &man.jme.4;, &man.re.4;, and &man.mxge.4; - driver support this feature. - - The &man.vlan.4; pseudo interface for IEEE 802.1Q VLAN - now ignore renaming of the parent's interface name. The - configured VLAN interfaces continue to work with the new - name while previously the configurations were removed as the - renaming happens. + Disks and Storage - The &man.ada.4; driver now supports - BIO_DELETE. For SSDs this uses - TRIM feature of DATA SET - MANAGEMENT command, as defined by ACS-2 - specification working draft. For Compact Flash use - CFA ERASE command, same as &man.ad.4; - does. This change realizes restoring write speed of SSDs - which supports TRIM command by doing - newfs -E - /dev/ada1, for - example. - - The &man.ahci.4; driver now supports SATA part of - Marvell 88SE912x controllers. - - The &man.ahci.4; driver now supports FIS-based (Frame - Information Structure) switching of port multiplier on - supported controllers. - - The &man.ahd.4; driver now supports three separated - error counters for correctable, uncorrectable, and fatal, in - &man.sysctl.8; MIB. - - A new kernel option has - been added. This turns &man.ata.4; controller drivers into - &man.cam.4; interface modules. When enabled, this option - deprecates all &man.ata.4; peripheral drivers and interfaces - such as ad and - acd, and allows &man.cam.4; drivers - ada, and cd and - interfaces to be natively used instead. Note that this is - not enabled by default in the GENERIC - kernel. - - A bug in the &man.ata.4; driver which can lead to - interrupt storms and command timeouts has been fixed. - - USB mass storage device support in the &man.ata.4; - driver has been removed. Note that this was not used in - GENERIC kernel and the &man.umass.4; - driver supports such devices for a long time. - - &os; &man.cam.3; SCSI framework has been improved: - - - - SATA and PATA support has been improved and it now - recognizes more detail device capabilities. For example, - the &man.ahci.4; and &man.siis.4; driver now reports maximum - tag number to the framework to optimize the NCQ - handling. - - - - A loader tunable - kern.cam.boot_delay has been added. - This controls the delay time before &man.cam.3; probes - the attached devices. - - - - SCSI error recovery for devices on buses without - automatic sense reporting has been improved. Typical - devices are on ATAPI and USB. For example, this allows - &man.cam.3; to wait, while CD drive loads disk, instead - of immediately return error status. - - - - The &man.cam.4; ATA transport layer now supports - Power-Up In Stand-by (PUIS). The PUIS is a configuration of - SATA or PATA drives to prevent them from automatic spin-up - when power is applied. A typical application is staggered - spin-up. - - - - The &man.cam.4; ATA transport layer now supports - negotiating and enabling additional SATA features such as - device initiated power management, Automatic Partial to - Slumber mode transition, and DMA auto-activation. - - - - A livelock issue of the &man.ciss.4; driver under a high - load has been fixed. - - A bug in the &man.fdc.4; driver which prevents the - kernel module from unloading has been fixed. - - The &man.glabel.8; now supports the following sysctl - variables for each label type to enable the labeling itself: - - kern.geom.label.ext2fs.enable -kern.geom.label.iso9660.enable -kern.geom.label.msdosfs.enable -kern.geom.label.ntfs.enable -kern.geom.label.reiserfs.enable -kern.geom.label.ufs.enable -kern.geom.label.ufsid.enable -kern.geom.label.gptid.enable -kern.geom.label.gpt.enable - - Note that all of them are also loader tunables. They - are enabled (set as 1) by default. - - &man.geom.8; providers including complex ones such as - &man.gconcat.8;, &man.gmirror.8;, &man.graid3.8, - &man.gstripe.8;, and some hardware RAID device drivers like - &man.twa.4; now inform its optimal access block size to the - upper layer. - - The &man.gmirror.8; utility now supports - configure - priority command to - change the providers priority. - - The balancing mode algorithm load - used in the &man.gmirror.8; utility has been changed and it - is now the default one instead of - split: - - - - Instead of measuring last request execution time for - each drive and choosing one with smallest time, use - averaged number of requests, running on each drive. This - information is more accurate and timely. It allows to - distribute load between drives in more even and - predictable way. - - - - For each drive track offset of the last submitted - request. If new request offset matches previous one or - close for some drive, prefer that drive. It allows to - significantly speedup simultaneous sequential reads. - - - - The &man.gmultipath.8; utility now supports - destroy, rotate, - getactive commands. - - A bug in the &man.graid3.8; which causes a panic when a - large request arrives has been fixed. This happens when - MAXPHYS is set as larger than 128k. - - The default block size of &man.gstripe.8; has been - increased from 4k to 64k. - - The GEOM_SCHED module has been added. - This supports scheduling disk I/O requests in a device - independent manner. A supported algorithm is an - anticipatory scheduler gsched_rr which - gives very nice performance improvements in presence of - competing random access patterns. See also &man.gsched.8; - manual page for more details. - - The HAST (Highly Available STorage) framework has been - added: - - - - This is a framework to allow transparently storing - data on two physically separated machines connected over - the TCP/IP network. HAST works in Primary-Secondary - (Master-Backup, Master-Slave) configuration, which means - that only one of the cluster nodes can be active at any - given time. Only Primary node is able to handle I/O - requests to HAST-managed devices. Currently HAST is - limited to two cluster nodes in total. - - - - This operates on block level; it provides disk-like - devices in /dev/hast/ directory for - use by file systems and/or applications. Working on - block level makes it transparent for file systems and - applications. There in no difference between using - HAST-provided device and raw disk, partition, etc. All - of them are just regular &man.geom.8; providers in - &os;. - - - - The userland part consists of &man.hastd.8;, - &man.hastctl.8;, and &man.hast.conf.5;. More details - can be found at . - - - - The &man.isp.4; driver has been improved in - stability. - - The &man.mvs.4; CAM ATA driver for Marvell - 88SX50XX/88SX60XX/88SX70XX/SoC SATA controllers has been - added. This driver supports same hardware as the - &man.ata.4; driver does, but provides many additional - features, such as NCQ and PMP. - - The &man.siis.4; driver now enables MSI by default on - SiI3124-based devices. This can be disabled by using a - hint.siis.0.msi - loader tunable. - - The Max Read Request Size in the &man.siis.4; driver for - PCIe chips has been increased from 512 to 1024 bytes for - better performance. - - The &man.twa.4; driver has been updated to the latest - version from LSI. + File Systems - The &man.msdosfs.5; subsystem is now MP-safe and a race - condition when a force unmount happens has been - fixed. - - &os; NFS subsystem now supports a timeout for the - negative name cache entries in the client. This avoids a - bogus negative name cache entry from persisting forever when - another client creates an entry with the same name within - the same NFS server time of day clock tick. The mount - option can be used to override - the default timeout interval (60 seconds) on a - per-mount-point basis. a Setting - to 0 - disables negative name caching for the mount point. - - A race condition in &os; NFS subsystem that occurs when - &man.nfsiod.8; threads are being created has been fixed. - This also fixes an interoperability issue found in - combination of a &os; NFS client and a Linux NFS - server. - - The inode number handling in &man.ffs.7; file system is - now unsigned. Previously some large inode numbers can be - treated as negative, and this issue shows up at file systems - with the size of more than 16Tb in 16k block case. The - &man.newfs.8; utility never create a file system with more - than 2^32 inodes by cutting back on the number of inodes per - cylinder group if necessary to stay under the limit. - - The UFS file system (&man.ffs.7;) now supports NFSv4 - ACL. - - &os; &man.VFS.9; subsystem now supports a new sysctl - variable vfs.vlru_allow_cache_src. This - allow vnlru kernel thread to reclaim - of the directory vnodes that are source of the namecache - records. This is not enabled by default because for - typical workload it would make namecache unusable, but - large nested directory tree easily puts any process that - accesses file system into one second wait for - vnlru kernel thread. - - The ZFS file system has been improved: - - - - It now supports NFSv4 ACL. - - - - The L2ARC code has been improved in stability and - performance. - - - - The zpool version has been updated to - version 14. It is now possible to use zpools created on - OpenSolaris 2009.06. - - - - A sysctl variable *** DIFF OUTPUT TRUNCATED AT 1000 LINES ***
