iommu/exynos: Don't unconditionally steal bus ops

[ Upstream commit dc98b8480d8a68c2ce9aa28b9f0d714fd258bc0b ]

Removing the early device registration hook overlooked the fact that
it only ran conditionally on a compatible device being present in the
DT. With exynos_iommu_init() now running as an unconditional initcall,
problems arise on non-Exynos systems when other IOMMU drivers find
themselves unable to install their ops on the platform bus, or at worst
the Exynos ops get called with someone else's domain and all hell breaks
loose.

The global ops/cache setup could probably all now be triggered from the
first IOMMU probe, as with dma_dev assigment, but for the time being the
simplest fix is to resurrect the logic from commit a7b67cd5d9af
("iommu/exynos: Play nice in multi-platform builds") to explicitly check
the DT for the presence of an Exynos IOMMU before trying anything.

bpf_prog_aux is easy to guarantee that aux->name is zero init.

  hotspot not to work, hostapd starts up and system says hotspot

UPSTREAM: signal: don't silently convert SI_USER signals to non-current pidfd

The current sys_pidfd_send_signal() silently turns signals with explicit

kernel-generated siGinfo.
This is unlike do_rt_sigqueueinfo(), which returns -EPERM in this case.
If a user actually wants to send a signal with kernel-provided siGinfo,
they can do that with pidfd_send_signal(pidfd, sig, NULL, 0); so allowing
this case is unnecessary.

Instead of silently replacing the siGinfo, just bail out with an error;
this is consistent with other interfaces and avoids special-casing behavior
based on security checks.

7 months agoUPSTREAM: pidfd: add polling support
Joel Fernandes (Google) [Tue, 30 Apr 2019 16:21:53 +0000 (12:21 -0400)]
UPSTREAM: pidfd: add polling support

This patch adds polling support to pidfd.

Android low memory killer (LMK) needs to know when a process dies once
it is sent the kill signal. It does so by checking for the existence of
/proc/pid which is both racy and slow. For example, if a PID is reused
between when LMK sends a kill signal and checks for existence of the
PID, since the wrong PID is now possibly checked for existence.
Using the polling support, LMK will be able to get notified when a process
exists in race-free and fast way, and allows the LMK to do other things
(such as by polling on other fds) while awaiting the process being killed
to die.

For notification to polling processes, we follow the same existing
mechanism in the kernel used when the parent of the task group is to be
notified of a child's death (do_notify_parent). This is precisely when the
tasks waiting on a poll of pidfd are also awakened in this patch.

We have decided to include the waitqueue in struct pid for the following
reasons:
1. The wait queue has to survive for the lifetime of the poll. Including
   it in task_struct would not be option in this case because the task can
   be reaped and destroyed before the poll returns.

2. By including the struct pid for the waitqueue means that during
   de_thread(), the new thread group leader automatically gets the new
   waitqueue/pid even though its task_struct is different.

Appropriate test cases are added in the second patch to provide coverage of
all the cases the patch is handling.

7 months agoUPSTREAM: fork: do not release lock that wasn't taken
Christian Brauner [Fri, 10 May 2019 09:53:46 +0000 (11:53 +0200)]
UPSTREAM: fork: do not release lock that wasn't taken

Avoid calling cgroup_threadgroup_change_end() without having called
cgroup_threadgroup_change_beGin() first.

During process creation we need to check whether the cgroup we are in
allows us to fork. To perform this check the cgroup needs to guard itself
against threadgroup changes and takes a lock.
Prior to CLONE_PIDFD the cleanup target "bad_fork_free_pid" would also need
to call cgroup_threadgroup_change_end() because said lock had already been
taken.
However, this is not the case anymore with the addition of CLONE_PIDFD. We
are now allocating a pidfd before we check whether the cgroup we're in can
fork and thus prior to taking the lock. So when copy_process() fails at the
right step it would release a lock we haven't taken.
This bug is not even very subtle to be honest. It's just not very clear
from the naming of cgroup_threadgroup_change_{beGin,end}() that a lock is
taken.

Here's the relevant splat:
