drm/dp_mst: Skip validating ports during destruction, just ref

[ Upstream commit c54c7374ff44de5e609506aca7c0deae4703b6d1 ]

Jerry Zuo pointed out a rather obscure hotplugging issue that it seems I
accidentally introduced into DRM two years ago.

Pretend we have a topology like this:

|- DP-1: mst_primary
   |- DP-4: active display
   |- DP-5: disconnected
   |- DP-6: active hub
      |- DP-7: active display
      |- DP-8: disconnected
      |- DP-9: disconnected

If we unplug DP-6, the topology starting at DP-7 will be destroyed but
it's payloads will live on in DP-1's VCPI allocations and thus require
removal. However, this removal currently fails because
drm_dp_update_payload_part1() will (rightly so) try to validate the port
before accessing it, fail then abort. If we keep going, eventually we
run the MST hub out of bandwidth and all new allocations will start to
fail (or in my case; all new displays just start flickering a ton).

We could just teach drm_dp_update_payload_part1() not to drop the port
ref in this case, but then we also need to teach
drm_dp_destroy_payload_step1() to do the same thing, then hope no one
ever adds anything to the that requires a validated port reference in
drm_dp_destroy_connector_work(). Kind of sketchy.

So let's go with a more clever solution: any port that
drm_dp_destroy_connector_work() interacts with is guaranteed to still
exist in memory until we say so. While said port might not be valid we
don't really care: that's the whole reason we're destroying it in the
first place! So, teach drm_dp_get_validated_port_ref() to use the all
mighty current_work() function to avoid attempting to validate ports
from the context of mgr->destroy_connector_work. I can't see any
situation where this wouldn't be safe, and this avoids having to play
whack-a-mole in the future of trying to work around port validation.

regulator: ab8500: Remove SYSCLKREQ from enum ab8505_regulator_id

commit 458ea3ad033fc86e291712ce50cbe60c3428cf30 upstream.

Those regulators are not actually supported by the AB8500 regulator
driver. There is no ab8500_regulator_info for them and no entry in
ab8505_regulator_match.

As such, they cannot be registered successfully, and looking them
up in ab8505_regulator_match causes an out-of-bounds array read.

4 years agoperf probe: Fix wrong address verification
Masami Hiramatsu [Fri, 25 Oct 2019 08:46:25 +0000 (17:46 +0900)]
perf probe: Fix wrong address verification

commit 07d369857808b7e8e471bbbbb0074a6718f89b31 upstream.

Since there are some DIE which has only ranges instead of the
combination of entrypc/highpc, address verification must use
dwarf_haspc() instead of dwarf_entrypc/dwarf_highpc.

Also, the ranges only DIE will have a partial code in different section
(e.g. unlikely code will be in text.unlikely as "FUNC.cold" symbol). In
that case, we can not use dwarf_entrypc() or die_entrypc(), because the
offset from original DIE can be a minus value.

Instead, this simply gets the symbol and offset from symtab.

Without this patch;

  # perf probe -D clear_tasks_mm_cpumask:1
  Failed to get entry address of clear_tasks_mm_cpumask
    Error: Failed to add events.

And with this patch:

  # perf probe -D clear_tasks_mm_cpumask:1
  p:probe/clear_tasks_mm_cpumask clear_tasks_mm_cpumask+0
  p:probe/clear_tasks_mm_cpumask_1 clear_tasks_mm_cpumask+5
  p:probe/clear_tasks_mm_cpumask_2 clear_tasks_mm_cpumask+8
  p:probe/clear_tasks_mm_cpumask_3 clear_tasks_mm_cpumask+16
  p:probe/clear_tasks_mm_cpumask_4 clear_tasks_mm_cpumask+82

Committer testing:

I managed to reproduce the above:

  [root@quaco ~]# perf probe -D clear_tasks_mm_cpumask:1
  p:probe/clear_tasks_mm_cpumask _text+919968
  p:probe/clear_tasks_mm_cpumask_1 _text+919973
  p:probe/clear_tasks_mm_cpumask_2 _text+919976
  [root@quaco ~]#

But then when trying to actually put the probe in place, it fails if I
use :0 as the offset:

  [root@quaco ~]# perf probe -L clear_tasks_mm_cpumask | head -5
  <clear_tasks_mm_cpumask@/usr/src/debug/kernel-5.2.fc30/linux-5.2.18-200.fc30.x86_64/kernel/cpu.c:0>
        0  void clear_tasks_mm_cpumask(int cpu)
        1  {
        2   struct task_struct *p;

  [root@quaco ~]# perf probe clear_tasks_mm_cpumask:0
  Probe point 'clear_tasks_mm_cpumask' not found.
    Error: Failed to add events.
  [root@quaco

The next patch is needed to fix this case.

This patch fixes an unintended sign extension on left shifts. From Colin
King: "Shifting a u8 left will cause the value to be promoted to an
integer. If the top bit of the u8 is set then the following conversion to
an u64 will sign extend the value causing the upper 32 bits to be set in

Fix this by using get_unaligned_be*() instead.

Commit 60e4cf67a58 (reiserfs: fix extended attributes on the root
directory) introduced a regression open_xa_root started returning
-EOPNOTSUPP but it was not handled properly in reiserfs_for_each_xattr.

When the reiserfs module is built without CONFIG_REISERFS_FS_XATTR,
deleting an inode would result in a warning and chowning an inode
would also result in a warning and then fail to complete.

With CONFIG_REISERFS_FS_XATTR enabled, the xattr root would always be
present for read-write operations.

This commit handles -EOPNOSUPP in the same way -ENODATA is handled.
