Linus Torvalds akazivisa kudzikamiswa kweshanduro 5.9.
Pakati pedzimwe shanduko, akaunza rutsigiro rweFSGSBASE mu5.9 kernel, iyo inofanirwa kuvandudza mamiriro ekuchinja maitiro pa AMD neIntel processors. FSGSBASE inobvumira zviri mukati meFS/GS marejista kuti zviverengeke uye zvigadziriswe kubva munzvimbo yemushandisi, izvo zvinofanirwa kuvandudza kushanda kwese kwakakanganiswa neSpecter/Metldown vulnerabilities. Tsigiro yacho pachayo yakawedzerwa neMicrosoft mainjiniya makore akati wandei apfuura.
Zvakare:
- yakawedzera rutsigiro rweRadeon RX 6000 "RDNA 2"
- yakawedzera rutsigiro rweNVMe drive zoning commands (NVMe zoned namespaces (ZNS))
- yekutanga rutsigiro rweBMM Power10
- kuvandudzwa kwakasiyana-siyana kune subsystem yekuchengetedza, yakawedzera dziviriro kubva pakushandiswa kweGPL layer yekubatanidza vatyairi vevaridzi vane kernel zvikamu.
- iyo simba rekushandisa modhi (Energy Model framework) ikozvino inotsanangura kwete chete maitiro ekushandiswa kwesimba kweCPU, asiwo yemidziyo yeperipheral.
- Yakawedzerwa REJECT paPREROUTING nhanho kuNetfilter
- ye AMD Zen uye mitsva yeCPU modhi, rutsigiro rweP2PDMA tekinoroji yakawedzerwa, iyo inokutendera kuti ushandise DMA kuendesa zvakananga data pakati pekurangarira kwemidziyo miviri yakabatana nePCI bhazi.
