Pull tracing cleanup from Steven Rostedt:
 "Remove second argument of __assign_str()

  The __assign_str() macro logic of the TRACE_EVENT() macro was
  optimized so that it no longer needs the second argument. The
  __assign_str() is always matched with __string() field that takes a
  field name and the source for that field:

    __string(field, source)

  The TRACE_EVENT() macro logic will save off the source value and then
  use that value to copy into the ring buffer via the __assign_str().

  Before commit c1fa617c ("tracing: Rework __assign_str() and
  __string() to not duplicate getting the string"), the __assign_str()
  needed the second argument which would perform the same logic as the
  __string() source parameter did. Not only would this add overhead, but
  it was error prone as if the __assign_str() source produced something
  different, it may not have allocated enough for the string in the ring
  buffer (as the __string() source was used to determine how much to
  allocate)

  Now that the __assign_str() just uses the same string that was used in
  __string() it no longer needs the source parameter. It can now be
  removed"

An issue was found on the RTL8125b when transmitting small fragmented
packets, whereby invalid entries were inserted into the transmit ring
buffer, subsequently leading to calls to dma_unmap_single() with a null
address.

This was caused by rtl8169_start_xmit() not noticing changes to nr_frags
which may occur when small packets are padded (to work around hardware
quirks) in rtl8169_tso_csum_v2().

To fix this, postpone inspecting nr_frags until after any padding has been
applied.

Jacob Keller says:

====================
intel: Interpret .set_channels() input differently

The ice and idpf drivers can trigger a crash with AF_XDP due to incorrect
interpretation of the asymmetric Tx and Rx parameters in their
.set_channels() implementations:

1. ethtool -l <IFNAME> -> combined: 40
2. Attach AF_XDP to queue 30
3. ethtool -L <IFNAME> rx 15 tx 15
   combined number is not specified, so command becomes {rx_count = 15,
   tx_count = 15, combined_count = 40}.
4. ethnl_set_channels checks, if there are any AF_XDP of queues from the
   new (combined_count + rx_count) to the old one, so from 55 to 40, check
   does not trigger.
5. the driver interprets `rx 15 tx 15` as 15 combined channels and deletes
   the queue that AF_XDP is attached to.

This is fundamentally a problem with interpreting a request for asymmetric
queues as symmetric combined queues.

Fix the ice and idpf drivers to stop interpreting such requests as a
request for combined queues. Due to current driver design for both ice and
idpf, it is not possible to support requests of the same count of Tx and Rx
queues with independent interrupts, (i.e. ethtool -L <IFNAME> rx 15 tx 15)
so such requests are now rejected.

Unlike ice, idpf does not check, if user has requested at least 1 combined
channel. Instead, it relies on a check in the core code. Unfortunately, the
check does not trigger for us because of the hacky .set_channels()
interpretation logic that is not consistent with the core code.

This naturally leads to user being able to trigger a crash with an invalid
input. This is how:

1. ethtool -l <IFNAME> -> combined: 40
2. ethtool -L <IFNAME> rx 0 tx 0
   combined number is not specified, so command becomes {rx_count = 0,
   tx_count = 0, combined_count = 40}.
3. ethnl_set_channels checks, if there is at least 1 RX and 1 TX channel,
   comparing (combined_count + rx_count) and (combined_count + tx_count)
   to zero. Obviously, (40 + 0) is greater than zero, so the core code
   deems the input OK.
4. idpf interprets `rx 0 tx 0` as 0 channels and tries to proceed with such
   configuration.

The issue has to be solved fundamentally, as current logic is also known to
cause AF_XDP problems in ice [0].

Interpret the command in a way that is more consistent with ethtool
manual [1] (--show-channels and --set-channels) and new ice logic.

Considering that in the idpf driver only the difference between RX and TX
queues forms dedicated channels, change the correct way to set number of
channels to:

ethtool -L <IFNAME> combined 10 /* For symmetric queues */
ethtool -L <IFNAME> combined 8 tx 2 rx 0 /* For asymmetric queues */

Recently, we had some servers upgraded to the latest kernel and noticed
the indicator from the user side showed worse results than before. It is
caused by the limitation of tp->rcv_wnd.

In 2018 commit a337531b ("tcp: up initial rmem to 128KB and SYN rwin
to around 64KB") limited the initial value of tp->rcv_wnd to 65535, most
CDN teams would not benefit from this change because they cannot have a
large window to receive a big packet, which will be slowed down especially
in long RTT. Small rcv_wnd means slow transfer speed, to some extent. It's
the side effect for the latency/time-sensitive users.

To avoid future confusion, current change doesn't affect the initial
receive window on the wire in a SYN or SYN+ACK packet which are set within
65535 bytes according to RFC 7323 also due to the limit in
__tcp_transmit_skb():

    th->window      = htons(min(tp->rcv_wnd, 65535U));

In one word, __tcp_transmit_skb() already ensures that constraint is
respected, no matter how large tp->rcv_wnd is. The change doesn't violate
RFC.

Let me provide one example if with or without the patch:
Before:
client   --- SYN: rwindow=65535 ---> server
client   <--- SYN+ACK: rwindow=65535 ----  server
client   --- ACK: rwindow=65536 ---> server
Note: for the last ACK, the calculation is 512 << 7.

After:
client   --- SYN: rwindow=65535 ---> server
client   <--- SYN+ACK: rwindow=65535 ----  server
client   --- ACK: rwindow=175232 ---> server
Note: I use the following command to make it work:
ip route change default via [ip] dev eth0 metric 100 initrwnd 120
For the last ACK, the calculation is 1369 << 7.

When we apply such a patch, having a large rcv_wnd if the user tweak this
knob can help transfer data more rapidly and save some rtts.

In the prueth_probe() function, if one of the calls to emac_phy_connect()
fails due to of_phy_connect() returning NULL, then the subsequent call to

Check the return code of emac_phy_connect and fail cleanly if there is an

In tls_init(), a write memory barrier is missing, and store-store
reordering may cause NULL dereference in tls_{setsockopt,getsockopt}.

CPU0                               CPU1
-----                              -----
// In tls_init()
// In tls_ctx_create()
ctx = kzalloc()
ctx->sk_proto = READ_ONCE(sk->sk_prot) -(1)

// In update_sk_prot()

                                   // In sock_common_setsockopt()

                                   ctx->sk_proto->setsockopt()    -(3)

In the above scenario, when (1) and (2) are reordered, (3) can observe
the NULL value of ctx->sk_proto, causing NULL dereference.

To fix it, we rely on rcu_assign_pointer() which implies the release
barrier semantic. By moving rcu_assign_pointer() after ctx->sk_proto is
initialized, we can ensure that ctx->sk_proto are visible when
changing sk->sk_prot.

The assignment of pps_enable is protected by tmreg_lock, but the read
operation of pps_enable is not. So the Coverity tool reports a lock
evasion warning which may cause data race to occur when running in a
multithread environment. Although this issue is almost impossible to
occur, we'd better fix it, at least it seems more logically reasonable,
and it also prevents Coverity from continuing to issue warnings.

This reverts commit 56573604.

According to the commit, it implements a manual AN-37 for some
"troublesome" Juniper MX5 switches. This appears to be a workaround for a
particular switch.

It has been reported that this causes a severe breakage for other switches,
including a Cisco 3560CX-12PD-S.

The code appears to be a workaround for a specific switch which fails to
link in SFI mode. It expects to see AN-37 auto negotiation in order to
link. The Cisco switch is not expecting AN-37 auto negotiation. When the
device starts the manual AN-37, the Cisco switch decides that the port is
confused and stops attempting to link with it. This persists until a power
cycle. A simple driver unload and reload does not resolve the issue, even
if loading with a version of the driver which lacks this workaround.

The authors of the workaround commit have not responded with
clarifications, and the result of the workaround is complete failure to
connect with other switches.

This appears to be a case where the driver can either "correctly" link with
the Juniper MX5 switch, at the cost of bricking the link with the Cisco
switch, or it can behave properly for the Cisco switch, but fail to link
with the Junipir MX5 switch. I do not know enough about the standards
involved to clearly determine whether either switch is at fault or behaving
incorrectly. Nor do I know whether there exists some alternative fix which
corrects behavior with both switches.

Revert the workaround for the Juniper switch.

Testing a network device that has large numbers of bytes/packets may
overflow. Using stats64 when comparing fixes this problem.

I tripped on this while iterating on a qstats patch for mlx5. See below
for confirmation without my added code that this is a bug.

Before this patch (with added debugging output):

$ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
rstat: 481708634 qstat: 666201639514 key: tx-bytes
not ok 3 stats.pkt_byte_sum
ok 4 stats.qstat_by_ifindex

Note the huge delta above ^^^ in the rtnl vs qstats.

After this patch:

$ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
ok 3 stats.pkt_byte_sum
ok 4 stats.qstat_by_ifindex

It looks like rtnl_fill_stats in net/core/rtnetlink.c will attempt to
copy the 64bit stats into a 32bit structure which is probably why this
behavior is occurring.

To show this is happening, you can get the underlying stats that the
stats.py test uses like this:

$ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \
           --do getlink --json '{"ifi-index": 7}'

And examine the output (heavily snipped to show relevant fields):

 'stats': {
           'multicast': 3739197,
           'rx-bytes': 1201525399,
           'rx-packets': 56807158,
           'tx-bytes': 492404458,
           'tx-packets': 1200285371,

 'stats64': {
             'multicast': 3739197,
             'rx-bytes': 35561263767,
             'rx-packets': 56807158,
             'tx-bytes': 666212335338,
             'tx-packets': 1200285371,

The stats.py test prior to this patch was using the 'stats' structure
above, which matches the failure output on my system.

Comparing side by side, rx-bytes and tx-bytes, and getting ethtool -S
output:

rx-bytes stats:    1201525399
rx-bytes stats64: 35561263767
rx-bytes ethtool: 36203402638

tx-bytes stats:      492404458
tx-bytes stats64: 666212335338
tx-bytes ethtool: 666215360113

Note that the above was taken from a system with an mlx5 NIC, which only
exposes ndo_get_stats64.

Based on the ethtool output and qstat output, it appears that stats.py
should be updated to use the 'stats64' structure for accurate
comparisons when packet/byte counters get very large.

To confirm that this was not related to the qstats code I was iterating
on, I booted a kernel without my driver changes and re-ran the test
which shows the qstats are skipped (as they don't exist for mlx5):

NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
ok 3 stats.pkt_byte_sum # SKIP qstats not supported by the device
ok 4 stats.qstat_by_ifindex # SKIP No ifindex supports qstats

But, fetching the stats using the CLI

$ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \
           --do getlink --json '{"ifi-index": 7}'

Shows the same issue (heavily snipped for relevant fields only):

 'stats': {
           'multicast': 105489,
           'rx-bytes': 530879526,
           'rx-packets': 751415,
           'tx-bytes': 2510191396,
           'tx-packets': 27700323,
 'stats64': {
             'multicast': 105489,
             'rx-bytes': 530879526,
             'rx-packets': 751415,
             'tx-bytes': 15395093284,
             'tx-packets': 27700323,

Comparing side by side with ethtool -S on the unmodified mlx5 driver:

tx-bytes stats:    2510191396
tx-bytes stats64: 15395093284
tx-bytes ethtool: 17718435810

With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.

This means that with:

  __string(field, mystring)

Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.

There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:

  git grep -l __assign_str | while read a ; do
      sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
      mv /tmp/test-file $a;
  done

I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.

Note, the same updates will need to be done for:

  __assign_str_len()
  __assign_rel_str()
  __assign_rel_str_len()

I tested this with both an allmodconfig and an allyesconfig (build only for both).

Use '%pD' to print out the filename, and print out the actual offset
within the file too, rather than just what the virtual address of the
mapping is (which doesn't tell you anything about any mapping offsets).

Also, use the exact vma_lookup() instead of find_vma() - the latter
looks up any vma _after_ the address, which is of questionable value
(yes, maybe you fell off the beginning, but you'd be more likely to fall
off the end).

Merge trivial x86 code generation annoyances

 - Introduce helper macros for clang asm input problems

 - use said macros to improve trivially stupid code generation issues in
   bitops and array_index_mask_nospec

 - also improve codegen with 32-bit array index comparisons

None of these really matter, but I look at code generation and profiles
fairly regularly, and these misfeatures caused the generated code to
look really odd and distract from the real issues.

* branch 'x86-codegen' of local tree:
  x86: improve bitop code generation with clang
  x86: improve array_index_mask_nospec() code generation
  clang: work around asm input constraint problems

This uses the new ASM_INPUT_RM macro to avoid the bad code generation
issue that clang has with more generic asm inputs.

This ends up avoiding generating code like this:

 	mov    %r10,(%rsp)
 	tzcnt  (%rsp),%rcx

which now becomes just

 	tzcnt  %r10,%rcx

and in the process ends up also removing a few unnecessary stack frames
when the only use was that pointless "asm uses memory location off stack".
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Don't force the inputs to be 'unsigned long', when the comparison can
easily be done in 32-bit if that's more appropriate.

Note that while we can look at the inputs to choose an appropriate size
for the compare instruction, the output is fixed at 'unsigned long'.
That's not technically optimal either, since a 32-bit 'sbbl' would often
be sufficient.

But for the outgoing mask we don't know how the mask ends up being used
(ie we have uses that have an incoming 32-bit array index, but end up
using the mask for other things).  That said, it only costs the extra
REX prefix to always generate the 64-bit mask.

[ A 'sbbl' also always technically generates a 64-bit mask, but with the
  upper 32 bits clear: that's fine for when the incoming index that will
  be masked is already 32-bit, but not if you use the mask to mask a
  pointer afterwards, like the file table lookup does ]

Work around clang problems with asm constraints that have multiple
possibilities, particularly "g" and "rm".

Clang seems to turn inputs like that into the most generic form, which
is the memory input - but to make matters worse, clang won't even use a
possible original memory location, but will spill the value to stack,
and use the stack for the asm input.

See

  https://github.com/llvm/llvm-project/issues/20571#issuecomment-980933442

for some explanation of why clang has this strange behavior, but the end
result is that "g" and "rm" really end up generating horrid code.

Pull staging driver updates from Greg KH:
 "Here is the big set of staging driver changes for 6.10-rc1. Not a lot
  of cleanups happening this kernel release, intern applications must be
  out of sync at the moment. But we did delete two drivers, wlan-ng and
  pi433, as they are no longer in use and the developers involved wanted
  them just gone entirely, allowing us to drop 19k lines from the tree.

  Other than the normal coding style cleanups here, there has been a lot
  of work on the vc04_services code, with the intent to finally get that
  out of staging hopefully soon. It's getting closer, which is nice to
  see.

  All of these have been in linux-next for a while with no reported
  issues"

sq_offset pointer. Remove the checks for it being NULL or not, it will
always be valid.
