patch 9.1.0089: qsort() comparison functions should be transitive Commit: https://github.com/vim/vim/commit/e06e43766500ecb4cd1031fa16cf9cbebdb222c1 Author: Christian Brabandt <cb@256bit.org> Date: Fri Feb 9 19:39:14 2024 +0100 patch 9.1.0089: qsort() comparison functions should be transitive Problem: qsort() comparison functions should be transitive Solution: Do not subtract values, but rather use explicit comparisons Improve qsort() comparison functions There has been a recent report on qsort() causing out-of-bounds read & write in glibc for non transitive comparison functions https://www.qualys.com/2024/01/30/qsort.txt Even so the bug is in glibc's implementation of the qsort() algorithm, it's bad style to just use substraction for the comparison functions, which may cause overflow issues and as hinted at in OpenBSD's manual page for qsort(): "It is almost always an error to use subtraction to compute the return value of the comparison function." So check the qsort() comparison functions and change them to be safe. closes: #13980 Signed-off-by: Christian Brabandt <cb@256bit.org>
