POSIX mandates 512-byte default block sizes for the df and du utilities, reflecting the typical size of blocks on disks. When Richard Stallman and the GNU team were implementing POSIX for the GNU operating system, they objected to this on the grounds that most people think in terms of 1024 byte (or 1 KiB) blocks.

The Linux API is composed out of the system call interface of the Linux kernel, the GNU C Library (by GNU), libcgroup, [1] libdrm, libalsa and libevdev [2] (by freedesktop.org). Linux API vs. POSIX API. The Linux API includes the kernel–user space API, which allows code in user space to access system resources and services of the Linux kernel ...

[citation needed] GNU-tar and BSD-tar followed this idea. Additionally, versions of tar from before the first POSIX standard from 1988 pad the values with spaces instead of zeroes. The checksum is calculated by taking the sum of the unsigned byte values of the header record with the eight checksum bytes taken to be ASCII spaces (decimal value ...
The behaviour is mandated by the POSIX C library that is used for interfacing with the kernel. POSIX specifies that the exec family of functions shall fail with EACCESS (permission denied) if the file denies execution permission (see execve – System Interfaces Reference, The Single UNIX Specification , Version 4 from The Open Group ).
glibc is free software released under the GNU Lesser General Public License. [3] The GNU C Library project provides the core libraries for the GNU system, as well as many systems that use Linux as the kernel. These libraries provide critical APIs including ISO C11, POSIX.1-2008, BSD, OS-specific APIs and more.
