The perf subsystem of Linux kernels from 2.6.37 up to 3.8.8 and RHEL6 kernel 2.6.32 contained a security vulnerability (CVE-2013-2094), which was exploited to gain root privileges by a local user. [ 17 ] [ 18 ] The problem was due to an incorrect type being used (32-bit int instead of 64-bit) in the event_id verification code path.
The relevant term is of the porting target is computer architecture; it comprises the instruction set(s) and the microarchitecture(s) of the processor(s), at least of the CPU. The target also comprises the "system design" of the entire system, be it a supercomputer , a desktop computer or some SoC , e.g. in case some unique bus is being used.
Additional to sar command, Linux sysstat package in Debian, [4] RedHat Enterprise Linux and SuSE provides additional reporting tools: : Collect, report, or save system activity information. – Linux User Commands Manual: Collect and store binary data in the system activity daily data file.
Debian is the basis for many other distributions, such as Ubuntu, Linux Mint, Tails, Proxmox, Kali Linux, Pardus, TrueNAS SCALE, and Astra Linux. Debian is one of the oldest operating systems based on the Linux kernel and, as of September 2023, the second oldest Linux distribution still in active development, only behind Slackware .

BogoMips (from "bogus" and MIPS) is a crude measurement of CPU speed made by the Linux kernel when it boots to calibrate an internal busy-loop. [1] An often-quoted definition of the term is "the number of million times per second a processor can do absolutely nothing".
On the Linux side, Debian also ships an ILP32 userspace. The underlying reason is the somewhat "more expensive" nature of LP64 code, [ 8 ] just like it has been shown for x86-64. In that regard, the x32 ABI extends the ILP32-on-64bit concept to the x86-64 platform.
