FreeBSD 13.1 tso tawm

Tom qab ib xyoos ntawm kev txhim kho, FreeBSD 13.1 tau tso tawm. Cov duab teeb tsa muaj rau amd64, i386, powerpc, powerpc64, powerpc64le, powerpcspe, armv6, armv7, aarch64 thiab riscv64 architectures. Tsis tas li ntawd, cov rooj sib txoos tau npaj rau cov tshuab virtualization (QCOW2, VHD, VMDK, raw) thiab huab cua puag ncig Amazon EC2, Google Compute Engine thiab Vagrant.

Hauv qhov tshiab version:

  • Tus tsav tsheb iwlwifi tau thov rau Intel wireless phaib nrog kev txhawb nqa rau cov chips tshiab thiab tus qauv 802.11ac. Tus tsav tsheb yog ua raws li Linux tsav tsheb thiab cov lej los ntawm net80211 Linux subsystem, uas khiav ntawm FreeBSD siv cov txheej txheem linuxkpi.
  • ZFS cov ntaub ntawv siv tau raug hloov kho rau kev tso tawm ntawm OpenZFS 2.1 nrog kev txhawb nqa rau dRAID (Distributed Spare RAID) thev naus laus zis thiab kev ua haujlwm tseem ceeb.
  • Ib tug tshiab rc tsab zfskeys tau ntxiv, uas koj tuaj yeem npaj tsis siv neeg decryption ntawm encrypted ZFS partitions ntawm lub khau raj theem.
  • Lub network pawg tau hloov tus cwj pwm rau IPv4 chaw nyob nrog tus lej xoom tom qab (xxx0), uas tam sim no siv tau los ua tus tswv tsev thiab tsis tshaj tawm los ntawm lub neej ntawd. Tus cwj pwm qub tuaj yeem xa rov qab siv sysctl net.inet.ip.broadcast_lowest.
  • Rau 64-ntsis architectures, tsim lub hauv paus system siv PIE (Position Independent Executable) hom yog qhib los ntawm lub neej ntawd. Txhawm rau lov tes taw, qhov teeb tsa WITHOUT_PIE tau muab.
  • Ntxiv lub peev xwm hu rau chroot los ntawm cov txheej txheem tsis tsim nyog uas NO_NEW_PRIVS chij tau teeb tsa. Lub hom tau qhib siv sysctl security.bsd.unprivileged_chroot. Qhov kev xaiv "-n" tau raug ntxiv rau qhov siv hluav taws xob chroot, uas teeb tsa tus chij NO_NEW_PRIVS rau cov txheej txheem ua ntej cais nws.
  • Ib hom rau kev hloov kho ntawm cov disk partitions tau muab ntxiv rau bsdinstall installer, tso cai rau koj los txuas cov ntawv faib faib ua haujlwm yam tsis muaj kev cuam tshuam cov neeg siv rau cov npe sib txawv. Cov lus pom zoo ua kom yooj yim rau kev tsim cov kev ua haujlwm siab ua haujlwm nruab rau cov tshuab thiab cov tshuab virtual nrog cov disks sib txawv.
  • Txhim kho khau raj txhawb nqa ntawm UEFI systems. Lub bootloader enables tsis siv neeg configuration ntawm lub copy_staging parameter nyob ntawm seb lub peev xwm ntawm lub loaded kernel.
  • Kev ua haujlwm tau ua los txhim kho kev ua haujlwm ntawm bootloader, nvme, rtsold, pib lub pseudo-random tooj generator thiab timer calibration, uas ua rau txo qis hauv lub sijhawm khau raj.
  • Ntxiv kev txhawb nqa rau NFS hla kev sib txuas lus encrypted raws li TLS 1.3. Qhov kev siv tshiab no siv cov kernel-muab TLS pawg los pab kom kho vajtse acceleration. Tsim rpc.tlsclntd thiab rpc.tlsservd cov txheej txheem nrog NFS-tshaj-TLS tus neeg siv khoom thiab kev siv neeg rau zaub mov, qhib los ntawm lub neej ntawd rau amd64 thiab arm64 architectures.
  • Rau NFSv4.1 thiab 4.2, qhov kev xaiv nconnect mount tau siv, uas txiav txim siab tus naj npawb ntawm TCP kev sib txuas tsim nrog lub server. Thawj qhov kev sib txuas yog siv rau cov lus RPC me me, thiab tus so yog siv los sib npaug cov tsheb khiav nrog cov ntaub ntawv xa mus.
  • Rau NFS server, sysctl vfs.nfsd.srvmaxio tau ntxiv, uas tso cai rau koj hloov qhov siab tshaj plaws I/O thaiv qhov loj (default 128Kb).
  • Txhim kho kho vajtse txhawb. Kev them nyiaj yug rau Intel I225 Ethernet maub los tau ntxiv rau tus tsav tsheb igc. Txhim kho kev txhawb nqa rau Big-endian systems. Ntxiv mgb tsav tsheb rau Microchip li LAN7430 PCIe Gigabit Ethernet Ethernet maub los
  • Cov neeg tsav tsheb dej khov siv rau Intel E800 Ethernet controllers tau hloov kho rau version 1.34.2-k, uas tam sim no suav nrog kev txhawb nqa rau kev xav txog cov xwm txheej firmware hauv lub kaw lus thiab pib siv DCB (Data center bridging) raws tu qauv txuas ntxiv tau ntxiv.
  • Amazon EC2 cov duab tau qhib los ntawm lub neej ntawd rau khau raj siv UEFI tsis yog BIOS.
  • Lub bhyve hypervisor tau hloov kho cov khoom siv rau kev ua raws li NVMe tsav los txhawb NVMe 1.4 specification. daws teeb meem nrog NVMe iovec thaum lub sij hawm hnyav I / O.
  • Lub tsev qiv ntawv CAM tau hloov dua siab tshiab los siv lub realpath hu thaum ua cov npe ntawm cov cuab yeej, uas tso cai rau cov cim txuas mus rau cov cuab yeej siv rau hauv camcontrol thiab smartctl utilities. camcontrol daws teeb meem nrog rub tawm firmware rau cov khoom siv.
  • Cov khoom siv hluav taws xob svnlite tau nres lub tsev ntawm lub hauv paus system.
  • Ntxiv Linux versions ntawm cov nqi hluav taws xob rau kev xam cov checksums (md5sum, sha1sum, thiab lwm yam) uas tau siv los ntawm kev hu rau BSD cov khoom siv uas twb muaj lawm (md5, sha1, thiab lwm yam) nrog rau qhov "-r" kev xaiv.
  • Kev them nyiaj yug rau NCQ kev tswj hwm tau ntxiv rau cov khoom siv mpsutil thiab cov ntaub ntawv hais txog lub adapter tau tshwm sim.
  • Hauv /etc/defaults/rc.conf, los ntawm lub neej ntawd, qhov "-i" kev xaiv tau qhib thaum hu rau rtsol thiab rtsold txheej txheem, uas yog lub luag haujlwm xa ICMPv6 RS (Router Solicitation) cov lus. Qhov kev xaiv no cuam tshuam qhov random ncua ua ntej xa lus.
  • Rau riscv64 thiab riscv64sf architectures, lub tsev ntawm cov tsev qiv ntawv nrog ASAN (chaw nyob sanitizer), UBSAN (Undefined Behavior Sanitizer), OpenMP thiab OFED (Open Fabrics Enterprise Distribution) yog qhib.
  • Cov teeb meem nrog kev txiav txim siab txog kev kho vajtse nrawm ntawm kev ua haujlwm cryptographic txhawb nqa los ntawm ARMv7 thiab ARM64 processors tau raug daws, uas tau ua kom nrawm nrawm ntawm kev ua haujlwm ntawm aes-256-gcm thiab sha256 algorithms ntawm ARM systems.
  • Rau lub powerpc architecture, lub pob tseem ceeb suav nrog LLDB debugger, tsim los ntawm LLVM project.
  • Lub tsev qiv ntawv OpenSSL tau hloov kho rau version 1.1.1o thiab nthuav dav nrog kev sib dhos ua kom zoo rau cov powerpc, powerpc64 thiab powerpc64le architectures.
  • SSH neeg rau zaub mov thiab cov neeg siv khoom tau hloov kho rau OpenSSH 8.8p1 nrog kev txhawb nqa rau rsa-sha digital kos npe tsis taus thiab kev txhawb nqa rau ob qhov kev lees paub siv cov khoom siv raws li FIDO / U2F raws tu qauv. Txhawm rau cuam tshuam nrog FIDO / U2F cov khoom siv, cov hom tseem ceeb tshiab "ecdsa-sk" thiab "ed25519-sk" tau ntxiv, uas siv ECDSA thiab Ed25519 digital kos npe algorithms, ua ke nrog SHA-256 hash.
  • Hloov kho tshiab ntawm cov ntawv thov thib peb suav nrog hauv lub hauv paus system: awk 20210215 (nrog thaj ua rau thaj uas lov tes taw kev siv thaj chaw rau thaj tsam thiab txhim kho kev sib raug zoo nrog gawk thiab mawk), zlib 1.2.12, libarchive 3.6.0.
