Linux System software package for correlated tracing of kernel, applications and libraries. GPL/LGPL/MIT OProfile: Linux Profiles everything running on the Linux system, including hard-to-profile programs such as interrupt handlers and the kernel itself. Sampling profiler for Linux that counts cache misses, stalls, memory fetches, etc.
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 compressed ROM/RAM file system (or cramfs) is a free (GPL'ed) read-only Linux file system designed for simplicity and space-efficiency. It is mainly used in embedded and small-footprint systems. Unlike a compressed image of a conventional file system, a cramfs image can be used as it is, i.e. without first decompressing it.
Visualization of a software buffer overflow. Data is written into A, but is too large to fit within A, so it overflows into B.. In programming and information security, a buffer overflow or buffer overrun is an anomaly whereby a program writes data to a buffer beyond the buffer's allocated memory, overwriting adjacent memory locations.
This way, LOC comes in handy to express the size of software among programmers with low levels of experience. Ubiquitous measure: LOC measures have been around since the earliest days of software. [15] As such, it is arguable that more LOC data is available than any other size measure.
In 2009 Squashfs was merged into Linux mainline as part of Linux 2.6.29. [ 8 ] [ 9 ] In that process, the backward-compatibility code for older formats was removed. Since then the Squashfs kernel-space code has been maintained in the Linux mainline tree, while the user-space tools remain on the project's GitHub page.
File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte. A large value is often expressed with a metric prefix (as in megabyte and gigabyte) or a binary prefix (as in mebibyte and gibibyte). [1]
In fact, if we consider files of length N, if all files were equally probable, then for any lossless compression that reduces the size of some file, the expected length of a compressed file (averaged over all possible files of length N) must necessarily be greater than N. [citation needed] So if we know nothing about the properties of the data ...
