[PATCH v3 0/5] vfs: Add timestamp range check support
From: Deepa Dinamani
Date: Sat Feb 18 2017 - 18:31:16 EST
The series is aimed at adding timestamp checking and policy
related to it to vfs.
The series was developed with discussions and guidance from
The original thread is at https://lkml.org/lkml/2016/11/2/294
Associated test: xfstests generic/402
Note that the above test will be run and will fail all filesystems that
do not have correct limits specified in the xfstests or the kernel or
that don't support times beyond the test dates. I will be submitting a
follow up xfstest and kernel patches to update all filesystems.
Currently ext4 is the only filesystem that reflects correct limits.
The branch is available at
Changes since v2:
* Introduce early boot param override for checks.
* Drop afs patch for timestamp limits.
Changes since v1:
* return EROFS on mount errors
* fix mtime copy/paste error in utimes
Deepa Dinamani (5):
vfs: Add file timestamp range support
vfs: Add checks for filesystem timestamp limits
ext4: Initialize timestamps limits
vfs: Add timestamp_truncate() api
utimes: Clamp the timestamps before update
