Description Michał Górny archtester

2022-05-27 07:00:45 UTC

In 5.x kernels, BINPRM_BUF_SIZE has been increased to 256 bytes:
https://github.com/torvalds/linux/commit/6eb3c3d0a52dca337e327ae8868ca1f44a712e02

Could we please backport this change to our 4.x genpatches?  Right now I'm seeing increased number of bugs reported by people using old kernel branches and hitting shebang length limit.
