A fost lansat\u0103 versiunea 3.2.0 a utilitarului de consol\u0103 nvtop, destinat monitoriz\u0103rii interactive a func\u021bion\u0103rii GPU-urilor \u0219i a acceleratoarelor hardware. Utilitarul permite vizualizarea utiliz\u0103rii, consumului de memorie \u0219i modific\u0103rilor de frecven\u021b\u0103 a GPU-ului pe grafice, precum \u0219i vizualizarea proceselor care solicit\u0103 cel mai mult GPU-ul. Sunt acceptate GPU-uri \u0219i acceleratoare de la companiile AMD, Intel, NVIDIA, Apple (M1 & M2), Huawei (Ascend), Qualcomm \u0219i Broadcom (VideoCore). Este posibil\u0103 monitorizarea simultan\u0103 a mai multor cipuri pe un singur ecran. <\/p>\n

Noua versiune implementeaz\u0103 suport pentru driverele Intel XE \u0219i Broadcom V3D (Raspberry Pi). A fost ad\u0103ugat suport pentru acceleratorul AI Google TPU (Tensor Processing Unit). Au fost ad\u0103ugate op\u021biunile \u00ab-P\u00bb \u0219i \u00ab-s\u00bb pentru a ascunde zona cu lista proceselor \u0219i pentru a salva starea \u00een format JSON.

\"Sunt<\/center> <\/p>\n

De asemenea, a fost lansat utilitarul Atop 2.11.1, destinat monitoriz\u0103rii interactive a parametrilor de func\u021bionare a sistemului \u0219i afi\u0219\u0103rii activit\u0103\u021bii proceselor. Spre deosebire de utilitarul top, programul atop ofer\u0103 mai multe detalii (CPU, GPU, memorie, discuri, re\u021bea, fire, containere) \u0219i posibilitatea de a salva periodic rapoartele \u00eentr-un fi\u0219ier pentru analiza ulterioar\u0103. Codul este scris \u00een limbajul C \u0219i este distribuit sub licen\u021ba GPLv2. <\/p>\n

Noua versiune remediaz\u0103 o vulnerabilitate (CVE-2025-31160) care permite unui utilizator local s\u0103 provoace o dep\u0103\u0219ire a bufferului atunci c\u00e2nd utilitarul atop este rulat de un alt utilizator. De exemplu, un utilizator f\u0103r\u0103 privilegii poate organiza un atac asupra administratorului care ruleaz\u0103 utilitarul atop. Problema este cauzat\u0103 de faptul c\u0103 atop suport\u0103 op\u021bional colectarea de statistici despre func\u021bionarea GPU-ului, care este gestionat de un proces separat atopgpud. Interac\u021biunea cu acest proces se realizeaz\u0103 printr-un port TCP. La pornire, atop \u00eencearc\u0103 s\u0103 se conecteze la acest port TCP \u0219i \u00eencarc\u0103 periodic statistici prin acesta, f\u0103r\u0103 a asigura o verificare adecvat\u0103 a dimensiunii datelor transmise. <\/p>\n

Metoda de atac const\u0103 \u00een faptul c\u0103 orice utilizator din sistem poate lansa pe portul de re\u021bea atopgpud propriul s\u0103u handler, care va returna date evident mai mari, ceea ce va duce la dep\u0103\u0219irea bufferului \u00een atop \u00een \u00eencercarea de a analiza statisticile. Posibilitatea de a crea un exploit func\u021bional pentru a executa codul nu a fost demonstrat\u0103 \u00eenc\u0103. \u00cen noua versiune atop, colectarea statisticilor prin TCP port este dezactivat\u0103 \u00een mod implicit \u0219i a fost ad\u0103ugat\u0103 op\u021biunea \u00ab-k\u00bb pentru a activa suportul atopgpud. De asemenea, au fost introduse verific\u0103ri suplimentare \u00een codul de analiz\u0103 a statisticilor pentru a preveni dep\u0103\u0219irile.

\"Sunt<\/center> <\/p>\n

\u00cen concluzie, se remarc\u0103 lansarea utilitarului asem\u0103n\u0103tor lui top, htop 3.4.0, care ofer\u0103 func\u021bionalit\u0103\u021bi precum derularea vertical\u0103 \u0219i orizontal\u0103 liber\u0103 a listei de procese, instrumente de evaluare a eficien\u021bei oper\u0103rii SMP \u0219i utilizarea fiec\u0103rui nucleu de procesor, vizualizarea \u00een mod arbore, op\u021biuni flexibile pentru configurarea interfe\u021bei, suport pentru filtrarea proceselor \u0219i gestionarea acestora (oprirea, ajustarea priorit\u0103\u021bii). Codul proiectului este scris \u00een C \u0219i este distribuit sub licen\u021ba GPLv2. <\/p>\n

\u00cen noua versiune a fost ad\u0103ugat urm\u0103rirea activit\u0103\u021bii GPU \u00een Linux; s-a \u00eembun\u0103t\u0103\u021bit func\u021bionarea pe calculatoarele Apple cu ARM; problemele de compilare pentru DragonFlyBSD, Darwin, NetBSD, OpenBSD \u0219i Solaris au fost rezolvate; s-a asigurat contabilizarea activit\u0103\u021bii pe disc \u0219i a re\u021belei \u00een DragonFlyBSD; a fost inclus\u0103 informa\u021bia despre firele de execu\u021bie \u0219i starea proceselor \u00een macOS; suportul pentru Unicode a fost extins; codul a fost repozi\u021bionat pentru a func\u021biona cu senzorii de temperatur\u0103; a crescut performan\u021ba codului pentru analiza statisticii; a fost ad\u0103ugat suport pentru ascunderea datelor despre cache \u0219i buffer-uri.
