Subject: [PATCH v3 00/10] ARM: remove set_fs callers and implementation
Date: Thu, 1 Oct 2020 16:12:23 +0200 [thread overview]
Message-ID: <20201001141233.119343-1-arnd@arndb.de> (raw)
Hi Christoph, Russell,
This is the updated version of my ARM set_fs patches, hopefully
I managed to address your previous concerns.
I have tested the oabi-compat changes using the LTP tests for the three
modified syscalls using an Armv7 kernel and a Debian 5 OABI user space.
I also tested the syscall_get_nr() in all combinations of OABI/EABI
kernel user space and fixed the bugs I found after Russell pointed
out one of those issues.
The series is now based on
https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git/log/?h=base.set_fs
with no extra patches, after I included a patch to define a
private TASK_SIZE_MAX.
Russell, if you would still consider this seris for the next merge
window and there are no further review comments, you can pull it
from
https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git \
arm-kill-set_fs-7
At this point I'd probably just defer it another release and
rebase once -rc1 is out, dropping the TASK_SIZE_MAX patch.
