Linux Kernel tso tawm 5.9

Tom qab ob lub hlis ntawm txoj kev loj hlob, Linus Torvalds tswvcuab kernel tso tawm Linux 5.9. Ntawm cov kev hloov pauv tseem ceeb tshaj plaws: txwv tsis pub xa cov cim los ntawm cov tswv lag luam mus rau GPL modules, ua kom cov ntsiab lus hloov pauv kev ua haujlwm siv FSGSBASE cov lus qhia processor, txhawb nqa cov duab duab compression siv Zstd, rov ua haujlwm tseem ceeb ntawm cov xov hauv cov ntsiav, kev txhawb nqa rau PRP (Parallel Redundancy Protocol), bandwidth-paub teem sijhawm nyob rau hauv lub sijhawm teem sijhawm, preemptive packing ntawm nplooj ntawv nco, muaj peev xwm chij CAP_CHECKPOINT_RESTOR, close_range() system hu, dm-crypt kev ua tau zoo, kev tshem tawm code rau 32-ntsis Xen PV qhua, tshiab slab tswj mechanism, kev xaiv " cawm" hauv Btrfs, kev txhawb nqa rau inline encryption hauv ext4 thiab F2FS.

Tus tshiab version suav nrog 16074 kho los ntawm 2011 tus tsim tawm,
thaj loj - 62 MB (hloov cuam tshuam 14548 cov ntaub ntawv, 782155 kab ntawm cov lej tau ntxiv, 314792 kab raug tshem tawm). Kwv yees li 45% ntawm tag nrho cov nthuav tawm hauv 5.9
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, 13%
muaj feem xyuam rau pawg network, 3% rau cov ntaub ntawv systems thiab 3% rau sab hauv
kernel subsystems.

ntsiab kev tsim kho tshiab:

  • Kev pabcuam nco thiab system
    • Tightened tiv thaiv kev siv GPL cov khaubncaws sab nraud povtseg rau kev sib txuas cov neeg tsav tsheb uas muaj cov khoom lag luam xa tawm tsuas yog rau cov qauv hauv qab daim ntawv tso cai GPL. Tus chij TAINT_PROPRIETARY_MODULE tam sim no tau txais qub txeeg qub teg hauv txhua lub modules uas import cov cim los ntawm cov modules nrog tus chij no. Yog tias GPL module sim xa cov cim los ntawm qhov tsis yog-GPL module, tom qab ntawd GPL module yuav tau txais TAINT_PROPRIETARY_MODULE daim ntawv lo thiab yuav tsis tuaj yeem nkag mus rau kernel Cheebtsam muaj tsuas yog rau GPL-tsim modules, txawm tias lub module tau dhau los ua cov cim los ntawm qeb "gplonly". Lub xauv rov qab (tsuas yog xa tawm EXPORT_SYMBOL_GPL nkaus xwb hauv cov qauv uas tau xa tawm EXPORT_SYMBOL_GPL), uas tuaj yeem ua txhaum txoj haujlwm ntawm tus tswv tsav tsheb, tsis raug siv (tsuas yog tus chij tus tswv tau txais txiaj ntsig, tab sis tsis yog GPL khi).
