Subject: [PATCH v3 0/8] Various fixes related to ptrace_may_access()
Date: Sun, 30 Oct 2016 22:46:30 +0100 [thread overview]
Message-ID: <1477863998-3298-1-git-send-email-jann@thejh.net> (raw)
Next try.
Changes to the individual patches are mostly documented in their
commit messages.
Added/removed patches:
- Added "proc: fix timerslack_ns handling"
- Removed "ptrace: warn on ptrace_may_access without proper locking"
(because of some reverted changes in the "proc: lock properly [...]"
patch)
Jann Horn (8):
exec: introduce cred_guard_light
exec: add privunit to task_struct
proc: use open()-time creds for ptrace checks
futex: don't leak robust_list pointer
proc: lock properly in ptrace_may_access callers
fs/proc: fix attr access check
proc: fix timerslack_ns handling
