Linux Kernel tso tawm 5.6

Tom qab ob lub hlis ntawm txoj kev loj hlob, Linus Torvalds tswvcuab kernel tso tawm Linux 5.6. Ntawm cov kev hloov pauv tseem ceeb tshaj plaws: kev koom ua ke ntawm WireGuard VPN interface, kev txhawb nqa rau USB4, lub npe chaw rau lub sijhawm, muaj peev xwm tsim TCP cov neeg siv khoom siv BPF, kev txhawb nqa thawj zaug rau MultiPath TCP, tshem tawm cov ntsiav ntawm qhov teeb meem 2038, "bootconfig" mechanism. , ZPO.

Tus tshiab version suav nrog 13702 kho los ntawm 1810 tus tsim tawm,
thaj loj - 40 MB (hloov cuam tshuam 11577 cov ntaub ntawv, 610012 kab ntawm cov lej tau ntxiv,
294828 kab tshem tawm). Kwv yees li 45% ntawm tag nrho cov nthuav tawm hauv 5.6
Cov kev hloov pauv muaj feem xyuam rau cov tsav tsheb, kwv yees li 15% ntawm cov kev hloov pauv
Tus cwj pwm ntawm kev hloov kho cov cai tshwj xeeb rau kho vajtse architectures, 12%
cuam ​​tshuam nrog pawg network, 4% nrog cov ntaub ntawv kaw lus thiab 3% nrog sab hauv
kernel subsystems.

ntsiab kev tsim kho tshiab:

• Network subsystem
  • Ntxiv kev siv lub VPN interface WireGuard, uas yog siv raws li niaj hnub encryption txoj kev (ChaCha20, Poly1305, Curve25519, BLAKE2s), yog ib qho yooj yim mus use, tsis muaj teeb meem, tau ua pov thawj nws tus kheej nyob rau hauv ib tug xov tooj ntawm kev siv loj thiab muab kev ua tau zoo heev (3,9 npaug sai dua OpenVPN nyob rau hauv cov nqe lus. ntawm throughput). WireGuard siv lub tswv yim ntawm encryption key routing, uas koom nrog txuas tus yuam sij ntiag tug rau txhua lub network interface thiab siv nws los khi cov yuam sij pej xeem. Cov yuam sij pej xeem raug pauv los tsim kom muaj kev sib txuas zoo ib yam li SSH. Cryptographic primitives xav tau rau WireGuard ua haujlwm nws yog nqa hla los ntawm lub tsev qiv ntawv zinc ua ib feem ntawm tus qauv Crypto API thiab suav nrog mus rau hauv lub hauv paus 5.5.
  • Pib Kev koom ua ke ntawm cov khoom tsim nyog los txhawb MPTCP (MultiPath TCP), qhov txuas ntxiv ntawm TCP raws tu qauv rau kev teeb tsa kev ua haujlwm ntawm TCP kev sib txuas nrog kev xa cov pob ntawv ib txhij ntawm ntau txoj hauv kev los ntawm kev sib txawv network cuam tshuam nrog cov chaw sib txawv IP. Rau kev siv network, xws li kev sib txuas ua ke zoo li kev sib txuas TCP tsis tu ncua, thiab tag nrho cov kev sib cais sib cais yog ua los ntawm MPTCP. Multipath TCP tuaj yeem siv rau ob qho tib si nce kev nkag mus thiab nce kev ntseeg tau. Piv txwv li, MPTCP tuaj yeem siv los npaj cov ntaub ntawv sib kis ntawm lub xov tooj smartphone siv WiFi thiab 4G txuas ib txhij, lossis txo nqi los ntawm kev sib txuas cov neeg rau zaub mov siv ntau qhov txuas pheej yig es tsis yog ib qho kim.
  • Ntxiv kev txhawb nqa rau lub network queue ua kev qhuab qhia sch_ets (Txhim khu kev xaiv kis tau tus mob, IEEE 802.1Qaz), uas muab lub peev xwm los faib cov bandwidth ntawm cov chav sib txawv ntawm kev khiav tsheb. Yog tias qhov thauj khoom ntawm cov chav kawm tshwj xeeb yog qis dua qhov kev faib tawm bandwidth, ETS tso cai rau lwm chav tsheb siv cov khoom siv (tsis siv) bandwidth. Qdisc sch_ets tau teeb tsa raws li PRIO kev qhuab qhia thiab siv cov chav kawm khiav tsheb los txhais cov kev txwv nruj thiab sib koom bandwidth. ETS ua haujlwm raws li kev sib koom ua ke ntawm kev qhuab qhia Ua ntej и DRR - yog tias muaj kev txwv nruj nruj, PRIO siv, tab sis yog tias tsis muaj tsheb khiav hauv kab, nws ua haujlwm zoo li DRR.
  • Ntxiv ib hom tshiab ntawm BPF cov kev pab cuam BPF_PROG_TYPE_STRUCT_OPS, uas tso cai rau koj los siv cov neeg ua haujlwm kernel los ntawm BPF. Tam sim no, cov yam ntxwv no tuaj yeem siv los siv TCP congestion tswj algorithms hauv daim ntawv ntawm BPF cov kev pab cuam. Ua piv txwv npaj siab BPF qhov kev pab cuam nrog kev siv algorithm DCTCP.
  • Txais mus rau hauv lub hauv paus hloov, txhais cov cuab yeej ethtool nrog ioctl() siv netlink interface. Lub interface tshiab ua rau nws yooj yim dua rau kev txuas ntxiv, txhim kho kev ua yuam kev, tso cai rau cov ntawv ceeb toom xa thaum lub xeev hloov pauv, ua kom yooj yim ntawm kev sib cuam tshuam ntawm cov ntsiav thiab cov neeg siv qhov chaw, thiab txo cov npe npe uas yuav tsum tau synchronized.
  • Ntxiv kev siv ntawm FQ-PIE (Flow Queue PIE) network queue tswj algorithm, txhawm rau txo qhov cuam tshuam tsis zoo ntawm cov pob ntawv nruab nrab ntawm cov khoom siv hluav taws xob (bufferbloat). FQ-PIE ua kom pom kev ua haujlwm siab thaum siv hauv cov tshuab nrog cable modems.
• Disk subsystem, I / O thiab cov ntaub ntawv systems
  • Rau Btrfs cov ntaub ntawv system ntxiv asynchronous kev siv ntawm DISCARD lub lag luam (kos npe dawb blocks uas tsis tas yuav tsum tau khaws cia lub cev lawm). Thaum pib, DISCARD cov haujlwm tau ua tiav synchronously, uas tuaj yeem ua rau kev ua haujlwm tsis zoo vim cov tsav tsheb tos rau cov lus txib kom ua tiav. Kev siv asynchronous tso cai rau koj tsis txhob tos lub tsav kom tiav DISCARD thiab ua qhov haujlwm no hauv keeb kwm yav dhau.
  • Hauv XFS ua tau Kev tu cov cai uas siv cov qub 32-ntsis sij hawm txee (lub sij hawm_t hom tau hloov los ntawm time64_t), ua rau 2038 teeb meem. Kho qhov yuam kev thiab nco kev noj nyiaj txiag uas tshwm sim ntawm 32-ntsis platforms. Cov cai tau rov ua haujlwm dua los ua haujlwm nrog cov cwj pwm txuas ntxiv.
  • Rau ext4 file system qhia paub Kev ua tau zoo ntawm kev ua tau zoo cuam tshuam nrog kev tuav inode xauv thaum ua haujlwm nyeem thiab sau ntawv. Txhim kho kev sau ntawv rov zoo hauv Direct I/O hom. Txhawm rau kom yooj yim rau kev kuaj mob ntawm cov teeb meem, thawj zaug thiab zaum kawg cov lej yuam kev raug muab khaws cia hauv superblock.
  • Ntawm F2FS cov ntaub ntawv kaw lus ua raws muaj peev xwm khaws cov ntaub ntawv hauv daim ntawv compressed. Rau ib tus neeg cov ntaub ntawv lossis cov npe, compression tuaj yeem siv tau siv cov lus txib "chattr +c file" lossis "chattr +c dir; kov dir/file". Txhawm rau txhawm rau tag nrho cov kev faib tawm, koj tuaj yeem siv qhov "-o compress_extension = ext" kev xaiv hauv mount utility.
  • Lub kernel suav nrog cov ntaub ntawv kaw lus Cheeb Tsam, uas yooj yim rau kev ua haujlwm qis nrog zoned cia khoom siv. Zoned drives txhais tau tias cov khoom siv ntawm cov hlau nplaum nyuaj lossis NVMe SSDs, qhov chaw khaws cia uas tau muab faib ua cov cheeb tsam uas tsim cov pab pawg ntawm cov blocks lossis cov sectors, uas tsuas yog cov ntaub ntawv sib txuas ntxiv tau tso cai, hloov kho tag nrho pawg blocks. FS ZoneFS tau tsim los ntawm Western Digital thiab koom nrog txhua cheeb tsam hauv kev tsav tsheb nrog cov ntaub ntawv sib cais uas tuaj yeem siv los khaws cov ntaub ntawv hauv hom nyoos yam tsis muaj kev tswj hwm ntawm cov haujlwm thiab qib thaiv, piv txwv li. Tso cai rau cov ntawv thov siv cov ntaub ntawv API es tsis txhob nkag mus ncaj qha rau lub cuab yeej thaiv siv ioctl.
  • Hauv NFS, mounting partitions dhau UDP yog neeg xiam los ntawm lub neej ntawd. Ntxiv kev txhawb nqa rau lub peev xwm los luam cov ntaub ntawv ncaj qha ntawm cov servers, txhais hauv NFS 4.2 specification. Ntxiv qhov kev xaiv mount tshiab "softreval", uas tso cai rau cached attribute qhov tseem ceeb siv nyob rau hauv cov ntaub ntawv ntawm server tsis ua hauj lwm. Piv txwv li, thaum qhia txog qhov kev xaiv no, tom qab lub server tsis muaj, nws tseem tuaj yeem txav mus raws txoj hauv kev hauv NFS muab faib thiab nkag mus rau cov ntaub ntawv uas tau teeb tsa hauv lub cache.
  • Ua tiav optimization ntawm kev ua tau zoo ntawm fs-verity mechanism, siv los saib xyuas kev ncaj ncees thiab kev lees paub ntawm tus kheej cov ntaub ntawv. Nce kev nyeem ntawv nrawm ua tsaug rau kev siv Merkle hash tsob ntoo. Qhov kev ua tau zoo ntawm FS_IOC_ENABLE_VERITY tau ua kom zoo thaum tsis muaj cov ntaub ntawv hauv lub cache (preemptive nyeem cov nplooj ntawv nrog cov ntaub ntawv tau siv).
• Virtualization thiab Kev Ruaj Ntseg
  • Lub peev xwm los lov tes taw SELinux module thaum khiav tau raug deprecated, thiab unloading ib tug twb qhib SELinux yuav raug txwv nyob rau hauv lub neej yav tom ntej. Txhawm rau lov tes taw SELinux koj yuav tsum dhau qhov "selinux = 0" parameter ntawm kab hais kom ua kernel.
