If CONFIG_TRIM_UNUSED_KSYMS is enabled and the kernel is built from
a pristine state, the vmlinux is linked twice.
Commit 3fdc7d3fe4c0 ("kbuild: link vmlinux only once for
CONFIG_TRIM_UNUSED_KSYMS") explains why this happens, but it did not fix
the issue at all.
Now I realized I had applied a wrong patch.
In v1 patch [1], the autoksyms_recursive target correctly recurses to
"$(MAKE) -f $(srctree)/Makefile autoksyms_recursive".
In v2 patch [2], I accidentally dropped the diff line, and it recurses to
"$(MAKE) -f $(srctree)/Makefile vmlinux".
Restore the code I intended in v1.

Convert the clock driver to specify parent data rather than parent
names, to actually bind using 'clock-names' specified in the DTS rather
than global clock names. Use parent_hws where possible to refer parent
clocks directly, skipping the lookup.

The sleep/wake state doesn't need to be set here because of specific

hasn't been modified. Add a note to the code so we aren't tempted to set

Some sc7180 Chromebooks actually have sc7180P (known by many names,
apparently, including possibly sc7180 Pro and sc7185). This is a
sc7180 part that has slightly higher clock speeds.
The official ID number allocated to these devices by Qualcomm is 495
so we'll add an entry to the table for them. Note that currently
shipping BIOS for these devices will actually end up reporting an ID
of 407 due to a bug but eventually a new BIOS will be released which
corrects it to 495.

Switch f2fs over to the functions that are replacing
fscrypt_set_test_dummy_encryption(). Since f2fs hasn't been converted
to the new mount API yet, this doesn't really provide a benefit for
f2fs. But it allows fscrypt_set_test_dummy_encryption() to be removed.
Also take the opportunity to eliminate an #ifdef.

Buffer split_desc_cache, the cache used to allcoate rmap list entries,
only by the default cache capacity (currently 40), not by doubling the
minimum (513). Aliasing L2 GPAs to L1 GPAs is uncommon, thus eager page
splitting is unlikely to need 500+ entries. And because each object is a
non-trivial 128 bytes (see struct pte_list_desc), those extra ~500
entries means KVM is in all likelihood wasting ~64kb of memory per VM.

Use an "unsigned int" for @access parameters instead of a "u32", mostly
to be consistent throughout KVM, but also because "u32" is misleading.
@access can actually squeeze into a u8, i.e. doesn't need 32 bits, but is
as an "unsigned int" because sp->role.access is an unsigned int.
No functional change intended.

usbnet uses the work usbnet_deferred_kevent() to perform tasks which may
sleep. On disconnect, completion of the work was originally awaited in
->ndo_stop(). But in 2003, that was moved to ->disconnect() by historic
commit "[PATCH] USB: usbnet, prevent exotic rtnl deadlock":
https://git.kernel.org/tglx/history/c/0f138bbfd83c
The change was made because back then, the kernel's workqueue
implementation did not allow waiting for a single work. One had to wait
for completion of *all* work by calling flush_scheduled_work(), and that
could deadlock when waiting for usbnet_deferred_kevent() with rtnl_mutex
held in ->ndo_stop().
The commit solved one problem but created another: It causes a
use-after-free in USB Ethernet drivers aqc111.c, asix_devices.c,
ax88179_178a.c, ch9200.c and smsc75xx.c:
* If the drivers receive a link change interrupt immediately before
disconnect, they raise EVENT_LINK_RESET in their (non-sleepable)
->status() callback and schedule usbnet_deferred_kevent().
* usbnet_deferred_kevent() invokes the driver's ->link_reset() callback,
which calls netif_carrier_{on,off}().
* That in turn schedules the work linkwatch_event().
Because usbnet_deferred_kevent() is awaited after unregister_netdev(),
netif_carrier_{on,off}() may operate on an unregistered netdev and
linkwatch_event() may run after free_netdev(), causing a use-after-free.
In 2010, usbnet was changed to only wait for a single instance of
usbnet_deferred_kevent() instead of *all* work by commit 23f333a2bfaf
("drivers/net: don't use flush_scheduled_work()").
Unfortunately the commit neglected to move the wait back to
->ndo_stop(). Rectify that omission at long last.

Similar to how it's done in the ice driver since 'eb087cd82864 ("ice:
propagate xdp_ring onto rx_ring")', read the XDP program once per NAPI
instead of once per descriptor cleaned. I measured an improvement in
throughput of 2% for the AF_XDP xdpsock l2fwd benchmark for zero copy mode
and 1% for copy mode.

====================
net: dp83822: fix interrupt floods
The false carrier and RX error counters, once half full, produce interrupt
floods. Since we do not use these counters, these interrupts should be disabled.

Some RX errors, notably when disconnecting the cable, increase the RCSR
register. Once half full (0x7fff), an interrupt flood is generated. I
measured ~3k/s interrupts even after the RX errors transfer was
stopped.
Since we don't read and clear the RCSR register, we should disable this
interrupt.

When unplugging an Ethernet cable, false carrier events were produced by
the PHY at a very high rate. Once the false carrier counter full, an
interrupt was triggered every few clock cycles until the cable was
replugged. This resulted in approximately 10k/s interrupts.
Since the false carrier counter (FCSCR) is never used, we can safely
disable this interrupt.
In addition to improving performance, this also solved MDIO read
timeouts I was randomly encountering with an i.MX8 fec MAC because of
the interrupt flood. The interrupt count and MDIO timeout fix were
tested on a v5.4.110 kernel.

Syzbot found a race between tun file and device destruction.
NAPIs live in struct tun_file which can get destroyed before
the netdev so we have to del them explicitly. The current
code is missing deleting the NAPI if the queue was detached
first.

When the third packet of 3WHS connection establishment
contains payload, it is added into socket receive queue
without the XFRM check and the drop of connection tracking
context.
This means that if the data is left unread in the socket
receive queue, conntrack module can not be unloaded.
As most applications usually reads the incoming data
immediately after accept(), bug has been hiding for
quite a long time.
Commit 68822bdf76f1 ("net: generalize skb freeing
deferral to per-cpu lists") exposed this bug because
even if the application reads this data, the skb
with nfct state could stay in a per-cpu cache for
an arbitrary time, if said cpu no longer process RX softirqs.
Many thanks to Ilya Maximets for reporting this issue,
and for testing various patches:
https://lore.kernel.org/netdev/20220619003919.394622-1-i.maximets@ovn.org/
Note that I also added a missing xfrm4_policy_check() call,
although this is probably not a big issue, as the SYN
packet should have been dropped earlier.
