x86/sched: Restore the SD_ASYM_PACKING flag in the DIE domain

Commit 8f2d6c41e5a6 ("x86/sched: Rewrite topology setup") dropped the
SD_ASYM_PACKING flag in the DIE domain added in commit 044f0e27dec6
("x86/sched: Add the SD_ASYM_PACKING flag to the die domain of hybrid
processors"). Restore it on hybrid processors.

The die-level domain does not depend on any build configuration and now
x86_sched_itmt_flags() is always needed. Remove the build dependency on
CONFIG_SCHED_[SMT|CLUSTER|MC].

sched/fair: Fix SMT4 group_smt_balance handling

For SMT4, any group with more than 2 tasks will be marked as
group_smt_balance. Retain the behaviour of group_has_spare by marking
the busiest group as the group which has the least number of idle_cpus.

Also, handle rounding effect of adding (ncores_local + ncores_busy) when
the local is fully idle and busy group imbalance is less than 2 tasks.
Local group should try to pull at least 1 task in this case so imbalance
should be set to 2 instead.

igb: clean up in all error paths when enabling SR-IOV

The reproducer was a simple script:

  #!/bin/sh
  for i in `seq 1 5`; do
    modprobe -rv igb
    modprobe -v igb max_vfs=1
    sleep 1
    modprobe -rv igb
  done

It turned out that this could only be reproduce on 82580 (quad and
dual-port), but not on 82576, i350 and i210.  Further debugging showed
that igb_enable_sriov()'s call to pci_enable_sriov() is failing, because
dev->is_physfn is 0 on 82580.

Prior to commit 50f303496d92 ("igb: Enable SR-IOV after reinit"),
igb_enable_sriov() jumped into the "err_out" cleanup branch.  After this
commit it only returned the error code.

So the cleanup didn't take place, and the incorrect VF setup in the
igb_adapter structure fooled the igb driver into assuming that VFs have
been set up where no VF actually existed.

Fix this problem by cleaning up again if pci_enable_sriov() fails.

ixgbe: fix timestamp configuration code

The commit in fixes introduced flags to control the status of hardware
configuration while processing packets. At the same time another structure
is used to provide configuration of timestamper to user-space applications.
The way it was coded makes this structures go out of sync easily. The
repro is easy for 82599 chips:

[root@hostname ~]# hwstamp_ctl -i eth0 -r 12 -t 1
current settings:
tx_type 0
rx_filter 0
new settings:
tx_type 1
rx_filter 12

The eth0 device is properly configured to timestamp any PTPv2 events.

[root@hostname ~]# hwstamp_ctl -i eth0 -r 1 -t 1
current settings:
tx_type 1
rx_filter 12
SIOCSHWTSTAMP failed: Numerical result out of range
The requested time stamping mode is not supported by the hardware.

The error is properly returned because HW doesn't support all packets
timestamping. But the adapter->flags is cleared of timestamp flags
even though no HW configuration was done. From that point no RX timestamps
are received by user-space application. But configuration shows good
values:

[root@hostname ~]# hwstamp_ctl -i eth0
current settings:
tx_type 1
rx_filter 12

Fix the issue by applying new flags only when the HW was actually
configured.

pmdomain: Rename the genpd subsystem to pmdomain

tcp: Fix bind() regression for v4-mapped-v6 non-wildcard address.

Since bhash2 was introduced, the example below does not work as expected.
These two bind() should conflict, but the 2nd bind() now succeeds.

  from socket import *

  s1 = socket(AF_INET6, SOCK_STREAM)
  s1.bind(('::ffff:127.0.0.1', 0))

  s2 = socket(AF_INET, SOCK_STREAM)
  s2.bind(('127.0.0.1', s1.getsockname()[1]))

During the 2nd bind() in inet_csk_get_port(), inet_bind2_bucket_find()
fails to find the 1st socket's tb2, so inet_bind2_bucket_create() allocates
a new tb2 for the 2nd socket.  Then, we call inet_csk_bind_conflict() that
checks conflicts in the new tb2 by inet_bhash2_conflict().  However, the
new tb2 does not include the 1st socket, thus the bind() finally succeeds.

In this case, inet_bind2_bucket_match() must check if AF_INET6 tb2 has
the conflicting v4-mapped-v6 address so that inet_bind2_bucket_find()
returns the 1st socket's tb2.

Note that if we bind two sockets to 127.0.0.1 and then ::FFFF:127.0.0.1,
the 2nd bind() fails properly for the same reason mentinoed in the previous
commit.

incorrect address comparison when searching for a bind2 bucket"), but
the blamed change is not the commit.

Before the commit, the leading zeros of ::FFFF:0.0.0.0 were treated
as 0.0.0.0, and the sequence above worked by chance.  Technically, this
case has been broken since bhash2 was introduced.

Note that if we bind() two sockets to 127.0.0.1 and then ::FFFF:0.0.0.0,
the 2nd bind() fails properly because we fall back to using bhash to
detect conflicts for the v4-mapped-v6 address.

selinux: fix handling of empty opts in selinux_fs_context_submount()

selinux_set_mnt_opts() relies on the fact that the mount options pointer
is always NULL when all options are unset (specifically in its
!selinux_initialized() branch. However, the new
selinux_fs_context_submount() hook breaks this rule by allocating a new
structure even if no options are set. That causes any submount created
before a SELinux policy is loaded to be rejected in
selinux_set_mnt_opts().

Fix this by making selinux_fs_context_submount() leave fc->security
set to NULL when there are no options to be copied from the reference
superblock.

driver core: return an error when dev_set_name() hasn't happened

The commit d21fdd07cea4 ("driver core: Return proper error code when
dev_set_name() fails") rewrote the logic of handling the dev_set_name()
error codes, but missed the point that initially set error value to
-EINVAL might be rewritten and hence the error path can't be triggered
at some circumstances. To fix this, make sure that error variable is
set to -EINVAL when other conditionals are false.

NFSD: fix possible oops when nfsd/pool_stats is closed.

If /proc/fs/nfsd/pool_stats is open when the last nfsd thread exits, then
when the file is closed a NULL pointer is dereferenced.
This is because nfsd_pool_stats_release() assumes that the
pointer to the svc_serv cannot become NULL while a reference is held.

This used to be the case but a recent patch split nfsd_last_thread() out
from nfsd_put(), and clearing the pointer is done in nfsd_last_thread().

This is easily reproduced by running
   rpc.nfsd 8 ; ( rpc.nfsd 0;true) < /proc/fs/nfsd/pool_stats

Fortunately nfsd_pool_stats_release() has easy access to the svc_serv
pointer, and so can call svc_put() on it directly.

this point.
It is however not entirely clear what the spinlock shall protect. It
could be the read-modify-write access to the NCFGR register, but this
is accessed in macb_set_rx_mode() and macb_set_rxcsum_feature() as well
without holding the spinlock. It could also be the register accesses
done in mog_init_rings() or macb_init_buffers(), but again these
functions are called without holding the spinlock in macb_hresp_error_task().
The locking seems fishy in this driver and it might deserve another look
before this patch is applied.

drm/i915: Only check eDP HPD when AUX CH is shared

Apparently Acer Chromebook C740 (BDW-ULT) doesn't have the
eDP HPD line properly connected, and thus fails the new
HPD check during eDP probe. The result is that we lose the
eDP output.

I suspect all such machines would be Chromebooks or other
Linux exclusive systems as the Windows driver likely wouldn't
work either. I did check a few other BDW machines here and
those do have eDP HPD connected, one of them even is a
different Chromebook (Samus).

To account for these funky machines let's skip the HPD check when
it looks like the eDP port is the only one using that specific AUX
channel. In case of multiple ports sharing the same AUX CH (eg. on
Asrock B250M-HDV) we still do the check and thus should correctly
ignore the eDP port in favor of the other DP port (usually a DP->VGA
converter).

PM: hibernate: Fix the exclusive get block device in test_resume mode

Commit 5904de0d735b ("PM: hibernate: Do not get block device exclusively
in test_resume mode") fixes a hibernation issue under test_resume mode.
That commit is supposed to open the block device in non-exclusive mode
when in test_resume. However the code does the opposite, which is against
its description.

In summary, the swap device is only opened exclusively by swsusp_check()
with its corresponding *close(), and must be in non test_resume mode.
This is to avoid the race condition that different processes scribble the
device at the same time. All the other cases should use non-exclusive mode.

Fix it by really disabling exclusive mode under test_resume.

Instead, do the common practice of having a "latest" softlink to the last

tracing/synthetic: Fix order of struct trace_dynamic_info

To make handling BIG and LITTLE endian better the offset/len of dynamic
fields of the synthetic events was changed into a structure of:

 struct trace_dynamic_info {
 #ifdef CONFIG_CPU_BIG_ENDIAN
u16 offset;
u16 len;
 #else
u16 len;
u16 offset;
 #endif
 };

to replace the manual changes of:

 data_offset = offset & 0xffff;
 data_offest = len << 16;

But if you look closely, the above is:

  <len> << 16 | offset

Which in little endian would be in memory:

 offset_lo offset_hi len_lo len_hi

and in big endian:

 len_hi len_lo offset_hi offset_lo

Which if broken into a structure would be:

 struct trace_dynamic_info {
 #ifdef CONFIG_CPU_BIG_ENDIAN
u16 len;
u16 offset;
 #else
u16 offset;
u16 len;
 #endif
 };

Which is the opposite of what was defined.

Fix this and just to be safe also add "__packed".

drm/amd/display: Adjust the MST resume flow

[Why]
In drm_dp_mst_topology_mgr_resume() today, it will resume the
mst branch to be ready handling mst mode and also consecutively do
the mst topology probing. Which will cause the dirver have chance
to fire hotplug event before restoring the old state. Then Userspace
will react to the hotplug event based on a wrong state.

[How]
Adjust the mst resume flow as:
1. set dpcd to resume mst branch status
2. restore source old state
3. Do mst resume topology probing

For drm_dp_mst_topology_mgr_resume(), it's better to adjust it to
pull out topology probing work into a 2nd part procedure of the mst
resume. Will have a follow up patch in drm.

x86/platform/uv: Use alternate source for socket to node data

The UV code attempts to build a set of tables to allow it to do
bidirectional socket<=>node lookups.

But when nr_cpus is set to a smaller number than actually present, the
cpu_to_node() mapping information for unused CPUs is not available to
build_socket_tables(). This results in skipping some nodes or sockets
when creating the tables and leaving some -1's for later code to trip.
over, causing oopses.

The problem is that the socket<=>node lookups are created by doing a
loop over all CPUs, then looking up the CPU's APICID and socket. But
if a CPU is not present, there is no way to start this lookup.

Instead of looping over all CPUs, take CPUs out of the equation
entirely. Loop over all APICIDs which are mapped to a valid NUMA node.
Then just extract the socket-id from the APICID.

This avoid tripping over disabled CPUs.

Merge branch 'sha1105-regressions'

Vladimir Oltean says:

====================
Fixes for SJA1105 DSA FDB regressions

A report by Yanan Yang has prompted an investigation into the sja1105
driver's behavior w.r.t. multicast. The report states that when adding
multicast L2 addresses with "bridge mdb add", only the most recently
added address works - the others seem to be overwritten. This is solved
by patch 3/5 (with patch 2/5 as a dependency for it).

Patches 4/5 and 5/5 fix a series of race conditions introduced during
the same patch set as the bug above, namely this one:
https://patchwork.kernel.org/project/netdevbpf/cover/20211024171757.3753288-1-vladimir.oltean@nxp.com/

Finally, patch 1/5 fixes an issue found ever since the introduction of
multicast forwarding offload in sja1105, which is that the multicast
addresses are visible (with the "self" flag) in "bridge fdb show".

net: dsa: sja1105: block FDB accesses that are concurrent with a switch reset

Currently, when we add the first sja1105 port to a bridge with
vlan_filtering 1, then we sometimes see this output:

sja1105 spi2.2: port 4 failed to read back entry for be:79:b4:9e:9e:96 vid 3088: -ENOENT
sja1105 spi2.2: Reset switch and programmed static config. Reason: VLAN filtering
sja1105 spi2.2: port 0 failed to add be:79:b4:9e:9e:96 vid 0 to fdb: -2

It is because sja1105_fdb_add() runs from the dsa_owq which is no longer
serialized with switch resets since it dropped the rtnl_lock() in the
blamed commit.

Either performing the FDB accesses before the reset, or after the reset,
is equally fine, because sja1105_static_fdb_change() backs up those
changes in the static config, but FDB access during reset isn't ok.

Make sja1105_static_config_reload() take the fdb_lock to fix that.

net: dsa: sja1105: serialize sja1105_port_mcast_flood() with other FDB accesses

sja1105_fdb_add() runs from the dsa_owq, and sja1105_port_mcast_flood()
runs from switchdev_deferred_process_work(). Prior to the blamed commit,
they used to be indirectly serialized through the rtnl_lock(), which
no longer holds true because dsa_owq dropped that.

So, it is now possible that we traverse the static config BLK_IDX_L2_LOOKUP
elements concurrently compared to when we change them, in
sja1105_static_fdb_change(). That is not ideal, since it might result in
data corruption.

Introduce a mutex which serializes accesses to the hardware FDB and to
the static config elements for the L2 Address Lookup table.

I can't find a good reason to add locking around sja1105_fdb_dump().
I'll add it later if needed.

net: dsa: sja1105: fix multicast forwarding working only for last added mdb entry

The commit cited in Fixes: did 2 things: it refactored the read-back
polling from sja1105_dynamic_config_read() into a new function,
sja1105_dynamic_config_wait_complete(), and it called that from
sja1105_dynamic_config_write() too.

What is problematic is the refactoring.

The refactored code from sja1105_dynamic_config_poll_valid() works like
the previous one, but the problem is that it uses another packed_buf[]
SPI buffer, and there was code at the end of sja1105_dynamic_config_read()
which was relying on the read-back packed_buf[]:

/* Don't dereference possibly NULL pointer - maybe caller
 * only wanted to see whether the entry existed or not.
 */
if (entry)
ops->entry_packing(packed_buf, entry, UNPACK);

After the change, the packed_buf[] that this code sees is no longer the
entry read back from hardware, but the original entry that the caller
passed to the sja1105_dynamic_config_read(), packed into this buffer.

This difference is the most notable with the SJA1105_SEARCH uses from
sja1105pqrs_fdb_add() - used for both fdb and mdb. There, we have logic
added by commit 728db843df88 ("net: dsa: sja1105: ignore the FDB entry
for unknown multicast when adding a new address") to figure out whether
the address we're trying to add matches on any existing hardware entry,
with the exception of the catch-all multicast address.

That logic was broken, because with sja1105_dynamic_config_read() not
working properly, it doesn't return us the entry read back from
hardware, but the entry that we passed to it. And, since for multicast,
a match will always exist, it will tell us that any mdb entry already
exists at index=0 L2 Address Lookup table. It is index=0 because the
caller doesn't know the index - it wants to find it out, and
sja1105_dynamic_config_read() does:

if (index < 0) { // SJA1105_SEARCH
/* Avoid copying a signed negative number to an u64 */
cmd.index = 0; // <- this
cmd.search = true;
} else {
cmd.index = index;
cmd.search = false;
}

So, to the caller of sja1105_dynamic_config_read(), the returned info
looks entirely legit, and it will add all mdb entries to FDB index 0.
There, they will always overwrite each other (not to mention,
potentially they can also overwrite a pre-existing bridge fdb entry),
and the user-visible impact will be that only the last mdb entry will be
forwarded as it should. The others won't (will be flooded or dropped,
depending on the egress flood settings).

Fixing is a bit more complicated, and involves either passing the same
packed_buf[] to sja1105_dynamic_config_wait_complete(), or moving all
the extra processing on the packed_buf[] to
sja1105_dynamic_config_wait_complete(). I've opted for the latter,
because it makes sja1105_dynamic_config_wait_complete() a bit more
self-contained.
