net: stmmac: Increase clk_ptp_ref rate

This series aims to increase the clk_ptp_ref rate to get the best
possible PTP timestamping resolution possible. Some modified disclosure
about my development/testing process from the RFC/RFT v1 follows.

Disclosure: I don't know much about PTP beyond what you can google in an
afternoon, don't have access to documentation about the stmmac IP,
and have only tested that (based on code comments and git commit
history) the programming of the subsecond register (and the clock rate)
makes more sense with these changes. Qualcomm has tested a similar
change offlist, verifying PTP more formally as I understand it.

The last version was an RFC/RFT, but I didn't get a lot of confirmation
that doing patch 3 in that series (essentially setting clk_ptp_ref to
whatever its max value is) for the whole stmmac ecosystem was a safe
idea. So I am erring on the side of caution and doing this for the
Qualcomm platform only. See v1 for an approach that would apply to
all stmmac platform drivers with clk_ptp_ref.

Qualcomm clocks can set their frequency to a variety of levels
generally. Let's use the max for clk_ptp_ref to ensure the best
timestamping resolution possible.

Without this, the default value of the clock is used. For sa8775p-ride
this is 19.2 MHz, far less than the 230.4 MHz possible.

net/tls: fixes for NVMe-over-TLS

here are some small fixes to get NVMe-over-TLS up and running.
The first set are just minor modifications to have MSG_EOR handled
for TLS, but the second set implements the ->read_sock() callback
for tls_sw.
The ->read_sock() callbacks return -EIO when encountering any TLS
Alert message, but as that's the default behaviour anyway I guess
we can get away with it.

TLS resets the protocol operations, so the read_sock() callback might
be changed, too.
In this case using sock->ops->readsock() in tls_strp_read_copyin() will
enter an infinite recursion if the read_sock() callback is calling
tls_rx_rec_wait() which will call into sock->ops->readsock() via
tls_strp_read_copyin().
But as tls_strp_read_copyin() is supposed to produce data from the
consumed socket and that socket is always a TCP socket we can call
tcp_read_sock() directly without having to deal with callbacks.

lock_vma_under_rcu() tries to guarantee that __anon_vma_prepare() can't
be called in the VMA-locked page fault path by ensuring that
vma->anon_vma is set.

However, this check happens before the VMA is locked, which means a
concurrent move_vma() can concurrently call unlink_anon_vmas(), which
disassociates the VMA's anon_vma.

This means we can get UAF in the following scenario:

virtio/vsock: some updates for MSG_PEEK flag

This patchset does several things around MSG_PEEK flag support. In
general words it reworks MSG_PEEK test and adds support for this flag
in SOCK_SEQPACKET logic. Here is per-patch description:

1) This is cosmetic change for SOCK_STREAM implementation of MSG_PEEK:
   1) I think there is no need of "safe" mode walk here as there is no
      "unlink" of skbs inside loop (it is MSG_PEEK mode - we don't change
      queue).
   2) Nested while loop is removed: in case of MSG_PEEK we just walk
      over skbs and copy data from each one. I guess this nested loop
      even didn't behave as loop - it always executed just for single
      iteration.

2) This adds MSG_PEEK support for SOCK_SEQPACKET. It could be implemented
   be reworking MSG_PEEK callback for SOCK_STREAM to support SOCK_SEQPACKET
   also, but I think it will be more simple and clear from potential
   bugs to implemented it as separate function thus not mixing logics
   for both types of socket. So I've added it as dedicated function.

3) This is reworked MSG_PEEK test for SOCK_STREAM. Previous version just
   sent single byte, then tried to read it with MSG_PEEK flag, then read
   it in normal way. New version is more complex: now sender uses buffer
   instead of single byte and this buffer is initialized with random
   values. Receiver tests several things:
   1) Read empty socket with MSG_PEEK flag.
   2) Read part of buffer with MSG_PEEK flag.
   3) Read whole buffer with MSG_PEEK flag, then checks that it is same
      as buffer from 2) (limited by size of buffer from 2) of course).
   4) Read whole buffer without any flags, then checks that it is same
      as buffer from 3).

4) This is MSG_PEEK test for SOCK_SEQPACKET. It works in the same way
   as for SOCK_STREAM, except it also checks combination of MSG_TRUNC
   and MSG_PEEK.

Florian Westphal says:

====================
netfilter fixes for net

1. On-demand overlap detection in 'rbtree' set can cause memory leaks.
   This is broken since 6.2.

2. An earlier fix in 6.4 to address an imbalance in refcounts during
   transaction error unwinding was incomplete, from Pablo Neira.

3. Disallow adding a rule to a deleted chain, also from Pablo.
   Broken since 5.9.

A race were found where set_channels could be called after registering
but before virtnet_set_queues() in virtnet_probe(). Fixing this by
moving the virtnet_set_queues() before netdevice registering. While at
it, use _virtnet_set_queues() to avoid holding rtnl as the device is
not even registered at that time.
