049a18f232 sysctl-6.4-rc1-v2
As mentioned on my first pull request for sysctl-next, for v6.4-rc1
 we're very close to being able to deprecating register_sysctl_paths().
 I was going to assess the situation after the first week of the merge
 window.
 
 That time is now and things are looking good. We only have one stragglers
 on the patch which had already an ACK for so I'm picking this up here now and
 the last patch is the one that uses an axe. Some careful eyeballing would
 be appreciated by others. If this doesn't get properly reviewed I can also
 just hold off on this in my tree for the next merge window. Either way is
 fine by me.
 
 I have boot tested the last patch and 0-day build completed successfully.

ASoC: Intel: soc-acpi-cht: Add quirk for Nextbook Ares 8A tablet
The Nextbook Ares 8A tablet which has Android as factory OS, has a buggy
DSDT with both ESSX8316 and 10EC5651 ACPI devices.

This tablet actually uses an rt5651 codec, but the matching code ends up
picking the ESSX8316 device, add a quirk to ignote the ESSX8316 device
on this tablet.

ASoC: codecs: wcd938x: fix accessing regmap on unattached devices
The WCD938x comes with three devices on two Linux drivers:
1. RX Soundwire device (wcd938x-sdw.c driver),
2. TX Soundwire device, which is used to access devices via regmap (also
   wcd938x-sdw.c driver),
3. platform device (wcd938x.c driver) - glue and component master,
   actually having most of the code using TX Soundwire device regmap.

When RX and TX Soundwire devices probe, the component master (platform
device) bind tries to write micbias configuration via TX Soundwire
regmap.  This might happen before TX Soundwire enumerates, so the regmap
access fails.  On Qualcomm SM8550 board with WCD9385:

  qcom-soundwire 6d30000.soundwire-controller: Qualcomm Soundwire controller v2.0.0 Registered
  wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:4 (ops wcd938x_sdw_component_ops)
  wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:3 (ops wcd938x_sdw_component_ops)
  qcom-soundwire 6ad0000.soundwire-controller: swrm_wait_for_wr_fifo_avail err write overflow

Fix the issue by:
1. Moving the regmap creation from platform device to TX Soundwire
   device.  The regmap settings are moved as-is with one difference:
   making the wcd938x_regmap_config const.
2. Using regmap in cache only mode till the actual TX Soundwire device
   enumerates and then sync the regmap cache.

89b7fd5d7f pwm: Changes for v6.4-rc1
The bulk of this is trivial conversions to the new .remove_new()
 callback for drivers as part of Uwe's effort to clean that up.
 
 Other than that a driver is added for Apple devices and various small
 fixes are included for existing drivers.
 
 Last but not least, this finally gets rid of the old pwm_request() and
 pwm_free() APIs are removed since the last user was dropped in v6.3.

798dec3304 x86-64: mm: clarify the 'positive addresses' user address rules
Dave Hansen found the "(long) addr >= 0" code in the x86-64 access_ok
checks somewhat confusing, and suggested using a helper to clarify what
the code is doing.

So this does exactly that: clarifying what the sign bit check is all
about, by adding a helper macro that makes it clear what it is testing.

This also adds some explicit comments talking about how even with LAM
enabled, any addresses with the sign bit will still GP-fault in the
non-canonical region just above the sign bit.

This is all what allows us to do the user address checks with just the
sign bit, and furthermore be a bit cavalier about accesses that might be
done with an additional offset even past that point.

(And yes, this talks about 'positive' even though zero is also a valid
user address and so technically we should call them 'non-negative'.  But
I don't think using 'non-negative' ends up being more understandable).

1dbc0a9515 x86: mm: remove 'sign' games from LAM untagged_addr*() macros
The intent of the sign games was to not modify kernel addresses when
untagging them.  However, that had two issues:

 (a) it didn't actually work as intended, since the mask was calculated
     as 'addr >> 63' on an _unsigned_ address. So instead of getting a
     mask of all ones for kernel addresses, you just got '1'.

 (b) untagging a kernel address isn't actually a valid operation anyway.

Now, (a) had originally been true for both 'untagged_addr()' and the
remote version of it, but had accidentally been fixed for the regular
version of untagged_addr() by commit e0bddc19ba ("x86/mm: Reduce
untagged_addr() overhead for systems without LAM").  That one rewrote
the shift to be part of the alternative asm code, and in the process
changed the unsigned shift into a signed 'sar' instruction.

And while it is true that we don't want to turn what looks like a kernel
address into a user address by masking off the high bit, that doesn't
need these sign masking games - all it needs is that the mm context
'untag_mask' value has the high bit set.

Which it always does.

So simplify the code by just removing the superfluous (and in the case
of untagged_addr_remote(), still buggy) sign bit games in the address
masking.

6ccdc91d6a x86: mm: remove architecture-specific 'access_ok()' define
There's already a generic definition of 'access_ok()' in the
asm-generic/access_ok.h header file, and the only difference bwteen that
and the x86-specific one is the added check for WARN_ON_IN_IRQ().

And it turns out that the reason for that check is long gone: it used to
use a "user_addr_max()" inline function that depended on the current
thread, and caused problems in non-thread contexts.

For details, see commits 7c4788950b ("x86/uaccess, sched/preempt:
Verify access_ok() context") and in particular commit ae31fe51a3
("perf/x86: Restore TASK_SIZE check on frame pointer") about how and why
this came to be.

But that "current task" issue was removed in the big set_fs() removal by
Christoph Hellwig in commit 47058bb54b ("x86: remove address space
overrides using set_fs()").

So the reason for the test and the architecture-specific access_ok()
define no longer exists, and is actually harmful these days.  For
example, it led various 'copy_from_user_nmi()' games (eg using
__range_not_ok() instead, and then later converted to __access_ok() when
that became ok).

And that in turn meant that LAM was broken for the frame following
before this series, because __access_ok() used to not do the address
untagging.

Accessing user state still needs care in many contexts, but access_ok()
is not the place for this test.

6014bc2756 x86-64: make access_ok() independent of LAM
The linear address masking (LAM) code made access_ok() more complicated,
in that it now needs to untag the address in order to verify the access
range.  See commit 74c228d20a ("x86/uaccess: Provide untagged_addr()
and remove tags before address check").

We were able to avoid that overhead in the get_user/put_user code paths
by simply using the sign bit for the address check, and depending on the
GP fault if the address was non-canonical, which made it all independent
of LAM.

And we can do the same thing for access_ok(): simply check that the user
pointer range has the high bit clear.  No need to bother with any
address bit masking.

In fact, we can go a bit further, and just check the starting address
for known small accesses ranges: any accesses that overflow will still
be in the non-canonical area and will still GP fault.

To still make syzkaller catch any potentially unchecked user addresses,
we'll continue to warn about GP faults that are caused by accesses in
the non-canonical range.  But we'll limit that to purely "high bit set
and past the one-page 'slop' area".

We could probably just do that "check only starting address" for any
arbitrary range size: realistically all kernel accesses to user space
will be done starting at the low address.  But let's leave that kind of
optimization for later.  As it is, this already allows us to generate
simpler code and not worry about any tag bits in the address.

The one thing to look out for is the GUP address check: instead of
actually copying data in the virtual address range (and thus bad
addresses being caught by the GP fault), GUP will look up the page
tables manually.  As a result, the page table limits need to be checked,
and that was previously implicitly done by the access_ok().

With the relaxed access_ok() check, we need to just do an explicit check
for TASK_SIZE_MAX in the GUP code instead.  The GUP code already needs
to do the tag bit unmasking anyway, so there this is all very
straightforward, and there are no LAM issues.

6e3220ba33 parisc: Fix argument pointer in real64_call_asm()
Fix the argument pointer (ap) to point to real-mode memory
instead of virtual memory.

It's interesting that this issue hasn't shown up earlier, as this could
have happened with any 64-bit PDC ROM code.

I just noticed it because I suddenly faced a HPMC while trying to execute
the 64-bit STI ROM code of an Visualize-FXe graphics card for the STI
text console.

567b35159e parisc: Cleanup mmap implementation regarding color alignment
This change simplifies the randomization of file mapping regions. It
reworks the code to remove duplication. The flow is now similar to
that for mips. Finally, we consistently use the do_color_align variable
to determine when color alignment is needed.

Tested on rp3440.

d755bd2cae parisc: Ensure page alignment in flush functions
Matthew Wilcox noticed, that if ARCH_HAS_FLUSH_ON_KUNMAP is defined
(which is the case for PA-RISC), __kunmap_local() calls
kunmap_flush_on_unmap(), which may call the parisc flush functions with
a non-page-aligned address and thus the page might not be fully flushed.

This patch ensures that flush_kernel_dcache_page_asm() and
flush_kernel_dcache_page_asm() will always operate on page-aligned
addresses.

829632dae8 parisc: Replace regular spinlock with spin_trylock on panic path
The panic notifiers' callbacks execute in an atomic context, with
interrupts/preemption disabled, and all CPUs not running the panic
function are off, so it's very dangerous to wait on a regular
spinlock, there's a risk of deadlock.

Refactor the panic notifier of parisc/power driver to make use
of spin_trylock - for that, we've added a second version of the
soft-power function. Also, some comments were reorganized and
trailing white spaces, useless header inclusion and blank lines
were removed.

c0b79b0ff5 ublk: add timeout handler
Add timeout handler, so that we can provide forward progress guarantee for
unprivileged ublk, which can't be trusted.

One thing is that sync() calls sync_bdevs(wait) for all block devices after
running sync_bdevs(no_wait), and if one device can't move on, the sync() won't
return any more.

Add timeout for unprivileged ublk to avoid such affect for other users which call
sync() syscall.

Meantime clear UBLK_F_USER_RECOVERY_REISSUE for unprivileged ublk since
that feature may cause IO hang too.

3899d94e38 drbd: correctly submit flush bio on barrier
When we receive a flush command (or "barrier" in DRBD), we currently use
a REQ_OP_FLUSH with the REQ_PREFLUSH flag set.

The correct way to submit a flush bio is by using a REQ_OP_WRITE without
any data, and set the REQ_PREFLUSH flag.

Since commit b4a6bb3a67 ("block: add a sanity check for non-write
flush/fua bios"), this triggers a warning in the block layer, but this
has been broken for quite some time before that.

So use the correct set of flags to actually make the flush happen.

It has to consistently use one method or the other to avoid warnings,

d246331b78 btrfs: don't free qgroup space unless specified
Boris noticed in his simple quotas testing that he was getting a leak
with Sweet Tea's change to subvol create that stopped doing a
transaction commit.  This was just a side effect of that change.

In the delayed inode code we have an optimization that will free extra
reservations if we think we can pack a dir item into an already modified
leaf.  Previously this wouldn't be triggered in the subvolume create
case because we'd commit the transaction, it was still possible but
much harder to trigger.  It could actually be triggered if we did a
mkdir && subvol create with qgroups enabled.

This occurs because in btrfs_insert_delayed_dir_index(), which gets
called when we're adding the dir item, we do the following:

  btrfs_block_rsv_release(fs_info, trans->block_rsv, bytes, NULL);

if we're able to skip reserving space.

The problem here is that trans->block_rsv points at the temporary block
rsv for the subvolume create, which has qgroup reservations in the block
rsv.

This is a problem because btrfs_block_rsv_release() will do the
following:

  if (block_rsv->qgroup_rsv_reserved >= block_rsv->qgroup_rsv_size) {
	  qgroup_to_release = block_rsv->qgroup_rsv_reserved -
		  block_rsv->qgroup_rsv_size;
	  block_rsv->qgroup_rsv_reserved = block_rsv->qgroup_rsv_size;
  }

The temporary block rsv just has ->qgroup_rsv_reserved set,
->qgroup_rsv_size == 0.  The optimization in
btrfs_insert_delayed_dir_index() sets ->qgroup_rsv_reserved = 0.  Then
later on when we call btrfs_subvolume_release_metadata() which has

  btrfs_block_rsv_release(fs_info, rsv, (u64)-1, &qgroup_to_release);
  btrfs_qgroup_convert_reserved_meta(root, qgroup_to_release);

qgroup_to_release is set to 0, and we do not convert the reserved
metadata space.

The problem here is that the block rsv code has been unconditionally
messing with ->qgroup_rsv_reserved, because the main place this is used
is delalloc, and any time we call btrfs_block_rsv_release() we do it
with qgroup_to_release set, and thus do the proper accounting.

The subvolume code is the only other code that uses the qgroup
reservation stuff, but it's intermingled with the above optimization,
and thus was getting its reservation freed out from underneath it and
thus leaking the reserved space.

The solution is to simply not mess with the qgroup reservations if we
don't have qgroup_to_release set.  This works with the existing code as
anything that messes with the delalloc reservations always have
qgroup_to_release set.  This fixes the leak that Boris was observing.

6a341729fb af_packet: Don't send zero-byte data in packet_sendmsg_spkt().
syzkaller reported a warning below [0].

We can reproduce it by sending 0-byte data from the (AF_PACKET,
SOCK_PACKET) socket via some devices whose dev->hard_header_len
is 0.

    struct sockaddr_pkt addr = {
        .spkt_family = AF_PACKET,
        .spkt_device = "tun0",
    };
    int fd;

    fd = socket(AF_PACKET, SOCK_PACKET, 0);
    sendto(fd, NULL, 0, 0, (struct sockaddr *)&addr, sizeof(addr));

We have a similar fix for the (AF_PACKET, SOCK_RAW) socket as
commit dc633700f0 ("net/af_packet: check len when min_header_len
equals to 0").

Let's add the same test for the SOCK_PACKET socket.

3ce29c17dc igc: read before write to SRRCTL register
igc_configure_rx_ring() function will be called as part of XDP program
setup. If Rx hardware timestamp is enabled prio to XDP program setup,
this timestamp enablement will be overwritten when buffer size is
written into SRRCTL register.

Thus, this commit read the register value before write to SRRCTL
register. This commit is tested by using xdp_hw_metadata bpf selftest
tool. The tool enables Rx hardware timestamp and then attach XDP program
to igc driver. It will display hardware timestamp of UDP packet with
port number 9092. Below are detail of test steps and results.

Command on DUT:
  sudo ./xdp_hw_metadata <interface name>

Command on Link Partner:
  echo -n skb | nc -u -q1 <destination IPv4 addr> 9092

Result before this patch:
  skb hwtstamp is not found!

Result after this patch:
  found skb hwtstamp = 1677800973.642836757

Optionally, read PHC to confirm the values obtained are almost the same:
Command:
  sudo ./testptp -d /dev/ptp0 -g
Result:
  clock time: 1677800973.913598978 or Fri Mar  3 07:49:33 2023

4a54903ff6 ionic: catch failure from devlink_alloc
Add a check for NULL on the alloc return.  If devlink_alloc() fails and
we try to use devlink_priv() on the NULL return, the kernel gets very
unhappy and panics. With this fix, the driver load will still fail,
but at least it won't panic the kernel.

9ad685dbfe ethtool: Fix uninitialized number of lanes
It is not possible to set the number of lanes when setting link modes
using the legacy IOCTL ethtool interface. Since 'struct
ethtool_link_ksettings' is not initialized in this path, drivers receive
an uninitialized number of lanes in 'struct
ethtool_link_ksettings::lanes'.

When this information is later queried from drivers, it results in the
ethtool code making decisions based on uninitialized memory, leading to
the following KMSAN splat [1]. In practice, this most likely only
happens with the tun driver that simply returns whatever it got in the
set operation.

As far as I can tell, this uninitialized memory is not leaked to user
space thanks to the 'ethtool_ops->cap_link_lanes_supported' check in
linkmodes_prepare_data().

Fix by initializing the structure in the IOCTL path. Did not find any
more call sites that pass an uninitialized structure when calling
'ethtool_ops::set_link_ksettings()'.
