ALSA: core: Fix SSID quirk lookup for subvendor=0
Some weird devices set the codec SSID vendor ID 0, and
snd_pci_quirk_lookup_id() loop aborts at the point although it should
still try matching with the SSID device ID. This resulted in a
missing quirk for some old Macs.
Fix the loop termination condition to check both subvendor and
subdevice.

devtmpfs regression fix: reconfigure on each mount
Prior to Linux v5.4 devtmpfs used mount_single() which treats the given
mount options as "remount" options, so it updates the configuration of
the single super_block on each mount.
Since that was changed, the mount options used for devtmpfs are ignored.
This is a regression which affect systemd - which mounts devtmpfs with
"-o mode=755,size=4m,nr_inodes=1m".
This patch restores the "remount" effect by calling reconfigure_single()

Merge branch 'signal-for-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull signal/exit/ptrace updates from Eric Biederman:
"This set of changes deletes some dead code, makes a lot of cleanups
which hopefully make the code easier to follow, and fixes bugs found
along the way.
The end-game which I have not yet reached yet is for fatal signals
that generate coredumps to be short-circuit deliverable from
complete_signal, for force_siginfo_to_task not to require changing
userspace configured signal delivery state, and for the ptrace stops
to always happen in locations where we can guarantee on all
architectures that the all of the registers are saved and available on
the stack.
Removal of profile_task_ext, profile_munmap, and profile_handoff_task
are the big successes for dead code removal this round.
A bunch of small bug fixes are included, as most of the issues
reported were small enough that they would not affect bisection so I
simply added the fixes and did not fold the fixes into the changes
they were fixing.
There was a bug that broke coredumps piped to systemd-coredump. I
dropped the change that caused that bug and replaced it entirely with
something much more restrained. Unfortunately that required some
rebasing.
Some successes after this set of changes: There are few enough calls
to do_exit to audit in a reasonable amount of time. The lifetime of
struct kthread now matches the lifetime of struct task, and the
pointer to struct kthread is no longer stored in set_child_tid. The
flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is
removed. Issues where task->exit_code was examined with
signal->group_exit_code should been examined were fixed.
There are several loosely related changes included because I am
cleaning up and if I don't include them they will probably get lost.
The original postings of these changes can be found at:
https://lkml.kernel.org/r/87a6ha4zsd.fsf@email.froward.int.ebiederm.org

https://lkml.kernel.org/r/87r19opkx1.fsf_-_@email.froward.int.ebiederm.org
I trimmed back the last set of changes to only the obviously correct
once. Simply because there was less time for review than I had hoped"

filemap: Use folio_put_refs() in filemap_free_folio()
This shrinks filemap_free_folio() by 55 bytes in my .config; 24 bytes from removing the VM_BUG_ON_FOLIO() and 31 bytes from unifying the small/large folio paths. We could just use folio_ref_sub() here since the caller should hold a reference (as the VM_BUG_ON_FOLIO() was asserting), but that's fragile.

net/smc: Fix hung_task when removing SMC-R devices
A hung_task is observed when removing SMC-R devices. Suppose that a link group has two active links(lnk_A, lnk_B) associated with two different SMC-R devices(dev_A, dev_B). When dev_A is removed, the link group will be removed from smc_lgr_list and added into lgr_linkdown_list. lnk_A will be cleared and smcibdev(A)->lnk_cnt will reach to zero. However, when dev_B is removed then, the link group can't be found in smc_lgr_list and lnk_B won't be cleared, making smcibdev->lnk_cnt never reaches zero, which causes a hung_task. This patch fixes this issue by restoring the implementation of smc_smcr_terminate_all() to what it was before commit |

ipv4: update fib_info_cnt under spinlock protection
In the past, free_fib_info() was supposed to be called
under RTNL protection.
This eventually was no longer the case.
Instead of enforcing RTNL it seems we simply can
move fib_info_cnt changes to occur when fib_info_lock
is held.
v2: David Laight suggested to update fib_info_cnt
only when an entry is added/deleted to/from the hash table,
as fib_info_cnt is used to make sure hash table size
is optimal.

powerpc/32s: Fix kasan_init_region() for KASAN
It has been reported some configuration where the kernel doesn't
boot with KASAN enabled.
This is due to wrong BAT allocation for the KASAN area:
---[ Data Block Address Translation ]---
0: 0xc0000000-0xcfffffff 0x00000000 256M Kernel rw m
1: 0xd0000000-0xdfffffff 0x10000000 256M Kernel rw m
2: 0xe0000000-0xefffffff 0x20000000 256M Kernel rw m
3: 0xf8000000-0xf9ffffff 0x2a000000 32M Kernel rw m
4: 0xfa000000-0xfdffffff 0x2c000000 64M Kernel rw m
A BAT must have both virtual and physical addresses alignment matching
the size of the BAT. This is not the case for BAT 4 above.
Fix kasan_init_region() by using block_size() function that is in
book3s32/mmu.c. To be able to reuse it here, make it non static and
change its name to bat_block_size() in order to avoid name conflict
with block_size() defined in <linux/blkdev.h>
Also reuse find_free_bat() to avoid an error message from setbat()
when no BAT is available.
And allocate memory outside of linear memory mapping to avoid
wasting that precious space.
With this change we get correct alignment for BATs and KASAN shadow
memory is allocated outside the linear memory space.
---[ Data Block Address Translation ]---
0: 0xc0000000-0xcfffffff 0x00000000 256M Kernel rw
1: 0xd0000000-0xdfffffff 0x10000000 256M Kernel rw

ALSA: usb-audio: add mapping for MSI MPG X570S Carbon Max Wifi.
The USB audio device 0db0:419c based on the Realtek ALC4080 chip exposes all playback volume controls as "PCM". This is makes distinguishing the individual functions hard. The added mapping distinguishes all playback volume controls as their respective function: - Speaker - for back panel output - Frontpanel Headphone - for front panel output - IEC958 - for digital output on the back panel This clarifies the individual volume control functions for users.

Tracing updates for 5.17:
New:
- The Real Time Linux Analysis (RTLA) tool is added to the tools directory.
- Can safely filter on user space pointers with: field.ustring ~ "match-string"
- eprobes can now be filtered like any other event.
- trace_marker(_raw) now uses stream_open() to allow multiple threads to safely
write to it. Note, this could possibly break existing user space, but we will
not know until we hear about it, and then can revert the change if need be.
- New field in events to display when bottom halfs are disabled.
- Sorting of the ftrace functions are now done at compile time instead of
at bootup.
Infrastructure changes to support future efforts:
- Added __rel_loc type for trace events. Similar to __data_loc but the offset
to the dynamic data is based off of the location of the descriptor and not
the beginning of the event. Needed for user defined events.
- Some simplification of event trigger code.
- Make synthetic events process its callback better to not hinder other
event callbacks that are registered. Needed for user defined events.
And other small fixes and clean ups.

net: wwan: Fix MRU mismatch issue which may lead to data connection lost
In pci_generic.c there is a 'mru_default' in struct mhi_pci_dev_info.
This value shall be used for whole mhi if it's given a value for a specific product.
But in function mhi_net_rx_refill_work(), it's still using hard code value MHI_DEFAULT_MRU.
'mru_default' shall have higher priority than MHI_DEFAULT_MRU.
And after checking, this change could help fix a data connection lost issue.

net: phy: marvell: add Marvell specific PHY loopback
Existing genphy_loopback() is not applicable for Marvell PHY. Besides
configuring bit-6 and bit-13 in Page 0 Register 0 (Copper Control
Register), it is also required to configure same bits in Page 2
Register 21 (MAC Specific Control Register 2) according to speed of
the loopback is operating.
Tested working on Marvell88E1510 PHY for all speeds (1000/100/10Mbps).
FIXME: Based on trial and error test, it seem 1G need to have delay between
soft reset and loopback enablement.

net: ethernet: sun4i-emac: Fix an error handling path in emac_probe()
A dma_request_chan() call is hidden in emac_configure_dma().
It must be released in the probe if an error occurs, as already done in
the remove function.
Add the corresponding dma_release_channel() call.

net: mscc: ocelot: don't dereference NULL pointers with shared tc filters
The following command sequence:

The reason is that the driver isn't prepared to receive two tc filters
with the same cookie. It unconditionally creates a new struct
ocelot_vcap_filter for each tc filter, and it adds all filters with the
same identifier (cookie) to the ocelot_vcap_block.
The problem is here, in ocelot_vcap_filter_del():
/* Gets index of the filter */
index = ocelot_vcap_block_get_filter_index(block, filter);
if (index < 0)
return index;
/* Delete filter */
ocelot_vcap_block_remove_filter(ocelot, block, filter);
/* Move up all the blocks over the deleted filter */
for (i = index; i < block->count; i++) {
struct ocelot_vcap_filter *tmp;
tmp = ocelot_vcap_block_find_filter_by_index(block, i);
vcap_entry_set(ocelot, i, tmp);
}
what will happen is ocelot_vcap_block_get_filter_index() will return the
index (@index) of the first filter found with that cookie. This is _not_
the index of _this_ filter, but the other one with the same cookie,
because ocelot_vcap_filter_equal() gets fooled.
Then later, ocelot_vcap_block_remove_filter() is coded to remove all
filters that are ocelot_vcap_filter_equal() with the passed @filter.
So unexpectedly, both filters get deleted from the list.
Then ocelot_vcap_filter_del() will attempt to move all the other filters
up, again finding them by index (@i). The block count is 2, @index was 0,
so it will attempt to move up filter @i=0 and @i=1. It assigns tmp =
ocelot_vcap_block_find_filter_by_index(block, i), which is now a NULL
pointer because ocelot_vcap_block_remove_filter() has removed more than
one filter.
As far as I can see, this problem has been there since the introduction
of tc offload support, however I cannot test beyond the blamed commit
due to hardware availability. In any case, any fix cannot be backported
that far, due to lots of changes to the code base.
Therefore, let's go for the correct solution, which is to not call
ocelot_vcap_filter_add() and ocelot_vcap_filter_del(), unless the filter
is actually unique and not shared. For the shared filters, we should
just modify the ingress port mask and call ocelot_vcap_filter_replace(),
a function introduced by commit

perf cpumap: Add is_dummy() method
Needed to check if a cpu_map is dummy, i.e. not a cpu map at all, for pid monitoring scenarios. This probably needs to move to libperf, but since perf itself is the first and so far only user, leave it at tools/perf/util/.
