When the PTP is enabled in hardware bit 6 of PTP_MSG_CONF1 register, the
transmit frame needs additional 4 bytes before the tail tag. It is
needed for all the transmission packets irrespective of PTP packets or
not.
The 4-byte timestamp field is 0 for frames other than Pdelay_Resp. For
the one-step Pdelay_Resp, the switch needs the receive timestamp of the
Pdelay_Req message so that it can put the turnaround time in the
correction field.
Since PTP has to be enabled for both Transmission and reception
timestamping, driver needs to track of the tx and rx setting of the all
the user ports in the switch.
Two flags hw_tx_en and hw_rx_en are added in ksz_port to track the
timestampping setting of each port. When any one of ports has tx or rx
timestampping enabled, bit 6 of PTP_MSG_CONF1 is set and it is indicated
to tag_ksz.c through tagger bytes. This flag adds 4 additional bytes to
the tail tag.  When tx and rx timestamping of all the ports are disabled,
then 4 bytes are not added.

While reviewing dependencies in some Kconfig files, I noticed the redundant
dependency "depends on PCI && PCI_MSI". The config PCI_MSI has always,
since its introduction, been dependent on the config PCI. So, it is
sufficient to just depend on PCI_MSI, and know that the dependency on PCI
is implicitly implied.

Reduce the dependencies of some network driver configs.

 - Add various missing READ_ONCE() to cmpxchg() loops prevent the

   rather large change to the s390 specific hardware sampling code and
   its current use of cmpxchg_double().

   Do the fix now to get it out of the way of Peter Zijlstra's
   cmpxchg128() work, and have something that can be backported. The
   added new code includes a private 128 bit cmpxchg variant which will
   be removed again after Peter's rework is available. Also note that
   this 128 bit cmpxchg variant is used to implement 128 bit
   READ_ONCE(), while strictly speaking it wouldn't be necessary, and
   _READ_ONCE() should also be sufficient; even though it isn't obvious
   for all converted locations that this is the case. Therefore use this
   implementation for for the sake of clarity and consistency for now.

 - The current nolibc header layout refrains from including files that

   and memset(), which are called by some architectures, but only at

vsock: update tools and error handling

Patchset consists of two parts:

1) Kernel patch
One patch from Bobby Eshleman. I took single patch from Bobby:
https://lore.kernel.org/lkml/d81818b868216c774613dd03641fcfe63cc55a45
.1660362668.git.bobby.eshleman@bytedance.com/ and use only part for
af_vsock.c, as VMCI and Hyper-V parts were rejected.

I used it, because for SOCK_SEQPACKET big messages handling was broken -
ENOMEM was returned instead of EMSGSIZE. And anyway, current logic which
always replaces any error code returned by transport to ENOMEM looks
strange for me also(for example in EMSGSIZE case it was changed to
ENOMEM).

2) Tool patches
Since there is work on several significant updates for vsock(virtio/
vsock especially): skbuff, DGRAM, zerocopy rx/tx, so I think that this
patchset will be useful.

This patchset updates vsock tests and tools a little bit. First of all
it updates test suite: two new tests are added. One test is reworked
message bound test. Now it is more complex. Instead of sending 1 byte
messages with one MSG_EOR bit, it sends messages of random length(one
half of messages are smaller than page size, second half are bigger)
with random number of MSG_EOR bits set. Receiver also don't know total
number of messages. Message bounds control is maintained by hash sum
of messages length calculation. Second test is for SOCK_SEQPACKET - it
tries to send message with length more than allowed. I think both tests
will be useful for DGRAM support also.

Third thing that this patchset adds is small utility to test vsock
performance for both rx and tx. I think this util could be useful as
'iperf'/'uperf', because:
1) It is small comparing to 'iperf' or 'uperf', so it very easy to add
   new mode or feature to it(especially vsock specific).
2) It allows to set SO_RCVLOWAT and SO_VM_SOCKETS_BUFFER_SIZE option.
   Whole throughtput depends on both parameters.
3) It is located in the kernel source tree, so it could be updated by
   the same patchset which changes related kernel functionality in vsock.

I used this util very often to check performance of my rx zerocopy
support(this tool has rx zerocopy support, but not in this patchset).

Here is comparison of outputs from three utils: 'iperf', 'uperf' and
'vsock_perf'. In all three cases sender was at guest side. rx and
tx buffers were always 64Kb(because by default 'uperf' uses 8K).

iperf:

   [ ID] Interval           Transfer     Bitrate
   [  5]   0.00-10.00  sec  12.8 GBytes  11.0 Gbits/sec sender
   [  5]   0.00-10.00  sec  12.8 GBytes  11.0 Gbits/sec receiver

uperf:

   Total     16.27GB /  11.36(s) =    12.30Gb/s       23455op/s

vsock_perf:

   tx performance: 12.301529 Gbits/s
   rx performance: 12.288011 Gbits/s

Results are almost same in all three cases.

Patchset was rebased and tested on skbuff v9 patch from Bobby Eshleman:
https://lore.kernel.org/netdev/20230107002937.899605-1-bobby.eshleman@bytedance.com/

Add timeout polling wait for auxiliary timestamps snapshot FIFO clear bit
(ATSFC) to clear. This is to ensure no residue fifo value is being read
erroneously.

====================
Intel Wired LAN Driver Updates 2023-01-10 (ixgbe, igc, iavf)

This series contains updates to ixgbe, igc, and iavf drivers.

Yang Yingliang adds calls to pci_dev_put() for proper ref count tracking
on ixgbe.

Christopher adds setting of Toggle on Target Time bits for proper
pulse per second (PPS) synchronization for igc.

Daniil Tatianin fixes, likely, copy/paste issue that misreported
destination instead of source for IP mask for iavf error.

The reference needs to keep the instance memory around, but also
the instance lock must remain valid. Users will take the lock,
check registration status and release the lock. mutex_destroy()
etc. belong in the same place as the freeing of the memory.

Unfortunately lockdep_unregister_key() sleeps so we need
to switch the an rcu_work.

Note that the problem is a bit hard to repro, because
devlink_pernet_pre_exit() iterates over registered instances.
AFAIU the instances must get devlink_free()d concurrently with
the namespace getting deleted for the problem to occur.

Before the commit under Fixes the page would have been released
from the pool before the napi_alloc_skb() call, so normal page
freeing was fine (released page == no longer in the pool).

After the change we just mark the page for recycling so it's still
in the pool if the skb alloc fails, we need to recycle.

Same commit added the same bug in the new bnxt_rx_multi_page_skb().

Currently, it used old rss size to get current tc mode. As a result, the
rss size is updated, but the tc mode is still configured based on the old
rss size.

So this patch fixes it by using the new rss size in both process.

There are still single reports of systems where ASPM incompatibilities
cause tx timeouts. It's not clear whom to blame, so let's disable

Merge tag 'perf-tools-fixes-for-v6.2-2-2023-01-11' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Make 'perf kmem' cope with the removal of some
   kmem:kmem_cache_alloc_node and kmem:kmalloc_node in the
   11e9734b ("mm/slab_common: unify NUMA and UMA version of
   tracepoints") commit, making sure it works with Linux >= 6.2 as well
   as with older kernels where those tracepoints are present.

 - Also make it handle the new "node" kmem:kmalloc and
   kmem:kmem_cache_alloc tracepoint field introduced in that same
   commit.

 - Fix hardware tracing PMU address filter duplicate symbol selection,
   that was preventing to match with static functions with the same name
   present in different object files.

 - Fix regression on what linux/types.h file gets used to build the "BPF
   prologue" 'perf test' entry, the system one lacks the fmode_t
   definition used in this test, so provide that type in the test
   itself.

 - Avoid build breakage with libbpf < 0.8.0 + LIBBPF_DYNAMIC=1. If the
   user asks for linking with the libbpf package provided by the distro,
   then it has to be >= 0.8.0. Using the libbpf supplied with the kernel
   would be a fallback in that case.

 - Fix the build when libbpf isn't available or explicitly disabled via
   NO_LIBBPF=1.

 - Don't try to install libtraceevent plugins as its not anymore in the
   kernel sources and will thus always fail.
