Udgaven af konsolv\u00e6rkt\u00f8jet nvtop 3.2.0 er blevet offentliggjort, designet til interaktiv overv\u00e5gning af GPU'er og hardwareacceleratorer. V\u00e6rkt\u00f8jet g\u00f8r det muligt at visualisere belastningen, hukommelsesforbruget og \u00e6ndringerne i GPU-frekvenser p\u00e5 grafer og se de processer, der mest aktivt belastende GPU'en. GPU'er og acceleratorer fra virksomhederne AMD, Intel, NVIDIA, Apple (M1 & M2), Huawei (Ascend), Qualcomm og Broadcom (VideoCore) underst\u00f8ttes. Det er muligt at overv\u00e5ge arbejdet fra flere chips p\u00e5 \u00e9n sk\u00e6rm. <\/p>\n

Den nye version implementerer support for Intel XE og Broadcom V3D-drivere (Raspberry Pi). Support til AI-acceleratoren Google TPU (Tensor Processing Unit) er ogs\u00e5 tilf\u00f8jet. Tilf\u00f8jede mulighederne \u2018-P\u2019 og -s\u2019 for at skjule processen-omr\u00e5det og for at gemme tilstanden i JSON-format.

\"Overv\u00e5gningsv\u00e6rkt\u00f8jerne<\/center> <\/p>\n

Samtidig er v\u00e6rkt\u00f8jet Atop 2.11.1 blevet udgivet, som er designet til interaktiv overv\u00e5gning af systemets driftsparametre og visning af procesaktiviteter. I mods\u00e6tning til v\u00e6rkt\u00f8jet top tilbyder atop en st\u00f8rre detaljegrad (CPU, GPU, hukommelse, diske, netv\u00e6rk, tr\u00e5de, containere) og muligheden for periodisk at gemme rapporter i en fil til efterf\u00f8lgende analyse. Koden er skrevet i C og distribueres under GPLv2-licensen. <\/p>\n

Den nye version l\u00f8ser en s\u00e5rbarhed (CVE-2025-31160), der giver en lokal bruger mulighed for at for\u00e5rsage et buffer overflow, n\u00e5r atop-v\u00e6rkt\u00f8jet k\u00f8res af en anden bruger. For eksempel kan en ikke-privilegeret bruger udf\u00f8re et angreb p\u00e5 en administrator, der k\u00f8rer atop. Problemet opst\u00e5r, fordi atop valgfrit underst\u00f8tter indsamling af GPU-statistik, som k\u00f8res i en separat proces kaldet atopgpud. Interaktionen med denne proces sker via en TCP-port. Ved opstart fors\u00f8ger atop at oprette en forbindelse til denne TCP-port og indl\u00e6ser regelm\u00e6ssigt statistik gennem den uden ordentlig kontrol af st\u00f8rrelsen p\u00e5 de overf\u00f8rte data. <\/p>\n

Angrebsmetoden g\u00e5r ud p\u00e5, at enhver bruger i systemet kan starte sin behandler p\u00e5 netv\u00e6rksporten atopgpud, som vil returnere data af en v\u00e6sentligt st\u00f8rre st\u00f8rrelse, hvilket vil f\u00f8re til buffer-overl\u00f8b i atop, n\u00e5r statistikken fors\u00f8ges analyseret. Muligheden for at skabe et fungerende exploit for at udf\u00f8re kode er endnu ikke blevet demonstreret. I den nye version af atop er indsamling af statistik gennem TCP-port som standard deaktiveret, og muligheden \u2018-k\u2019 tilf\u00f8jes for at aktivere support for atopgpud. Derudover er der tilf\u00f8jet ekstra kontrol i kodeanalysen af statistikken for at forhindre overl\u00f8b.

\"Overv\u00e5gningsv\u00e6rkt\u00f8jerne<\/center> <\/p>\n

Afslutningsvis kan det n\u00e6vnes, at en top-lignende kommandolinieunhed, htop 3.4.0, er blevet udgivet, bem\u00e6rkelsesv\u00e6rdig for funktioner som fri vertikal og horisontal rulle af proceslisten, v\u00e6rkt\u00f8jer til vurdering af effektiviteten af SMP og brugen af hver CPU-kerne, tilstedev\u00e6relsen af en tr\u00e6strukturvisningsfunktion, fleksible muligheder for tilpasning af brugergr\u00e6nsefladen, samt st\u00f8tte til procesfiltrering og -styring (afslutning, justering af prioritet). Projektkoden er skrevet i C og distribueres under GPLv2-licensen. <\/p>\n

I den nye version er der tilf\u00f8jet overv\u00e5gning af GPU-aktivitet i Linux; forbedret ydeevne p\u00e5 Apple ARM-computere; l\u00f8st byggeproblemer for DragonFlyBSD, Darwin, NetBSD, OpenBSD og Solaris; taget h\u00f8jde for disk- og netv\u00e6rksaktivitet i DragonFlyBSD; tilf\u00f8jet information om tr\u00e5de og processtatus i macOS; udvidet Unicode-support; omarbejdet koden til arbejde med temperatursensorer; forbedret kodeydelse til statistikparsing; tilf\u00f8jet support til at skjule data om cache og buffere.
