From: Andrew Lukoshko <alukoshko@almalinux.org>
Subject: [PATCH AlmaLinux 8 RT] ptrace: require CAP_SYS_PTRACE when task has no mm
kABI-safe AlmaLinux backport of upstream commit 31e62c2ebbfd
("ptrace: slightly saner 'get_dumpable()' logic") posted at
https://github.com/torvalds/linux/commit/31e62c2ebbfdc3fe3dbdf5e02c92a9dc67087a3a
The upstream fix adds a 'user_dumpable:1' bit to task_struct and
caches the last dumpability in exit_mm() so __ptrace_may_access()
can require CAP_SYS_PTRACE when the target has no mm (e.g. kernel
threads or already-exited user tasks). That layout change to
task_struct breaks kABI on RHEL/AlmaLinux 8 (the symtype signature
of struct task_struct is referenced by stablelist exports such as
__put_task_struct(), sched_setscheduler(), set_cpus_allowed_ptr()
and wake_up_process()), so we cannot import the field/exit_mm
hunks as-is. AlmaLinux 8's exit_mm() also predates the upstream
rewrite that the second hunk targets.
Take the minimal kABI-safe slice instead: when task->mm == NULL,
require CAP_SYS_PTRACE in init_user_ns unconditionally. This closes
the Qualys Security Advisory hole -- mm-less targets no longer pass
the dumpability check by default -- without touching task_struct or
exit.c. The only behavioural delta versus upstream is that a user
task that has already cleared its mm in exit_mm() (a dying/zombie
task) now also requires CAP_SYS_PTRACE to attach, instead of being
remembered as previously dumpable. Such targets are rarely ptraced
in practice.
Verified to apply with `patch -p1 -F0` (no offset, no fuzz, no rejects)
against kernel-rt-4.18.0-553.124.1.rt7.465.el8_10.
