Subject: [patch 11/14] revert "fs/binfmt_elf: fix PT_LOAD p_align values for loaders"
Date: Thu, 14 Apr 2022 19:13:55 -0700 [thread overview]
Message-ID: <20220415021356.1B0B3C385A1@smtp.kernel.org> (raw)
In-Reply-To: <20220414191240.9f86d15a3e3afd848a9839a6@linux-foundation.org>

Subject: revert "fs/binfmt_elf: fix PT_LOAD p_align values for loaders"
925346c129da11 ("fs/binfmt_elf: fix PT_LOAD p_align values for loaders")
is an attempt to fix regressions due to 9630f0d60fec5f ("fs/binfmt_elf:
use PT_LOAD p_align values for static PIE").
But regressionss continue to be reported:
https://lore.kernel.org/lkml/cb5b81bd-9882-e5dc-cd22-54bdbaaefbbc@leemhuis.info/
https://bugzilla.kernel.org/show_bug.cgi?id=215720
https://lkml.kernel.org/r/b685f3d0-da34-531d-1aa9-479accd3e21b@leemhuis.info
This patch reverts the fix, so the original can also be reverted.
