Subject: [patch V4 00/12] uaccess: Provide and use scopes for user access
Date: Wed, 22 Oct 2025 14:49:02 +0200 (CEST) [thread overview]
Message-ID: <20251022102427.400699796@linutronix.de> (raw)
This is a follow up on the V3 feedback:
https://lore.kernel.org/20251017085938.150569636@linutronix.de
Changes vs. V3:
- Remove the superflouous if (1) in the scope macro - Andrew
- Use asm_inline in the x86 conversion - Andrew
- Rename to scoped_user_*_access(), remove underscores, use a void
intermediate pointer and add a comment vs. access range - David
- Use read scope in select - PeterZ
- Fix comments, shorten local variables and remove pointless brackets -
Mathieu
- Simplify the coccinelle script, which needs still more polishing -
Julia
The series is based on v6.18-rc1 and also available from git:
git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git uaccess/masked
Thanks,
tglx
