The seccomp benchmark runs five scenarios, one calibration run with no
seccomp filters enabled then four further runs each adding a filter. The
calibration run times itself for 15s and then each additional run executes
for the same number of times.

Currently the seccomp tests, including the benchmark, run with an extended
120s timeout but this is not sufficient to robustly run the tests on a lot
of platforms. Sample timings from some recent runs:

   Platform          Run 1  Run 2  Run 3  Run 4
   ---------         -----  -----  -----  -----
   PowerEdge R200    16.6s  16.6s  31.6s  37.4s
   BBB (arm)         20.4s  20.4s  54.5s
   Synquacer (arm64) 20.7s  23.7s  40.3s

The x86 runs from the PowerEdge are quite marginal and routinely fail, for
the successful run reported here the timed portions of the run are at
117.2s leaving less than 3s of margin which is frequently breached. The
added overhead of adding filters on the other platforms is such that there
is no prospect of their runs fitting into the 120s timeout, especially
on 32 bit arm where there is no BPF JIT.

While we could lower the time we calibrate for I'm also already seeing the
currently completing runs reporting issues with the per filter overheads
not matching expectations:

Let's instead raise the timeout to 180s which is only a 50% increase on the
current timeout which is itself not *too* large given that there's only two
tests in this suite.

The event filter function test has been failing in our internal test
farm:

| # not ok 33 event filter function - test event filtering on functions

Running the test in verbose mode indicates that this is because the test
erroneously determines that kmem_cache_free() is the most common caller
of kmem_cache_free():

  # # + cut -d: -f3 trace
  # # + sed s/call_site=([^+]*)+0x.*/1/
  # # + sort
  # # + uniq -c
  # # + sort
  # # + tail -n 1
  # # + sed s/^[ 0-9]*//
  # # + target_func=kmem_cache_free

... and as kmem_cache_free() doesn't call itself, setting this as the
filter function for kmem_cache_free() results in no hits, and
consequently the test fails:

  # # + grep kmem_cache_free trace
  # # + grep kmem_cache_free
  # # + wc -l
  # # + hitcnt=0
  # # + grep kmem_cache_free trace
  # # + grep -v kmem_cache_free
  # # + wc -l
  # # + misscnt=0
  # # + [ 0 -eq 0 ]
  # # + exit_fail

This seems to be because the system in question has tasks with ':' in
their name (which a number of kernel worker threads have). These show up
in the trace, e.g.

  test:.sh-1299    [004] .....  2886.040608: kmem_cache_free: call_site=putname+0xa4/0xc8 ptr=000000000f4d22f4 name=names_cache

... and so when we try to extact the call_site with:

  cut -d: -f3 trace | sed 's/call_site=\([^+]*\)+0x.*/\1/'

... the 'cut' command will extrace the column containing
'kmem_cache_free' rather than the column containing 'call_site=...', and
the 'sed' command will leave this unchanged. Consequently, the test will
decide to use 'kmem_cache_free' as the filter function, resulting in the
failure seen above.

Fix this by matching the 'call_site=<func>' part specifically to extract
the function name.

The original version of the mitigation would patch in the calls to the

will patch in the CALL to srso_alias_untrain_ret() directly.

However, even if commit e7c25c44 ("x86/cpu: Cleanup the untrain
mess") meant well in trying to clean up the situation, due to micro-
architectural reasons, the untraining routine srso_alias_untrain_ret()
must be the target of a CALL instruction and not of a JMP instruction as
it is done now.

The code wasn't exactly wrong, but it was very odd, and it used
FOLL_FORCE together with FOLL_WRITE when it really didn't need to (it
only set FOLL_WRITE for writable mappings, so then the FOLL_FORCE was
pointless).

It also pointlessly called __get_user_pages() even when it knew it
wouldn't populate anything because the vma wasn't accessible and it
explicitly tested for and did *not* set FOLL_FORCE for inaccessible
vma's.

This code does need to use FOLL_FORCE, because we want to do fault in
writable shared mappings, but then the mapping may not actually be
readable.  And we don't want to use FOLL_WRITE (which would match the
permission of the vma), because that would also dirty the pages, which
we don't want to do.

For very similar reasons, FOLL_FORCE populates a executable-only mapping
with no read permissions. We don't have a FOLL_EXEC flag.

Yes, it would probably be cleaner to split FOLL_WRITE into two bits (for
separate permission and dirty bit handling), and add a FOLL_EXEC flag
for the "GUP executable page" case.  That would allow us to avoid
FOLL_FORCE entirely here.

But that's not how our FOLL_xyz bits have traditionally worked, and that
would be a much bigger patch.

So this at least avoids the FOLL_FORCE | FOLL_WRITE combination that
made one of my experimental validation patches trigger a warning.  That
warning was a false positive (and my experimental patch was incomplete
anyway), but it all made me look at this and decide to clean at least
this small case up.

Commit

  8117961d98fb2 ("x86/efi: Disregard setup header of loaded image")

dropped the memcopy of the image's setup header into the boot_params
struct provided to the core kernel, on the basis that EFI boot does not
need it and should rely only on a single protocol to interface with the
boot chain. It is also a prerequisite for being able to increase the
section alignment to 4k, which is needed to enable memory protections
when running in the boot services.

So only the setup_header fields that matter to the core kernel are
populated explicitly, and everything else is ignored. One thing was
overlooked, though: the initrd_addr_max field in the setup_header is not
used by the core kernel, but it is used by the EFI stub itself when it
loads the initrd, where its default value of INT_MAX is used as the soft
limit for memory allocation.

This means that, in the old situation, the initrd was virtually always
loaded in the lower 2G of memory, but now, due to initrd_addr_max being
0x0, the initrd may end up anywhere in memory. This should not be an
issue principle, as most systems can deal with this fine. However, it
does appear to tickle some problems in older UEFI implementations, where
the memory ends up being corrupted, resulting in errors when unpacking
the initramfs.

So set the initrd_addr_max field to INT_MAX like it was before.

ip_local_out() and other functions can pass skb->sk as function argument.

If the skb is a fragment and reassembly happens before such function call
returns, the sk must not be released.

This affects skb fragments reassembled via netfilter or similar
modules, e.g. openvswitch or ct_act.c, when run as part of tx pipeline.

Eric Dumazet made an initial analysis of this bug.  Quoting Eric:
  Calling ip_defrag() in output path is also implying skb_orphan(),
  which is buggy because output path relies on sk not disappearing.

  A relevant old patch about the issue was :
  8282f274 ("inet: frag: Always orphan skbs inside ip_defrag()")

  [..]

  net/ipv4/ip_output.c depends on skb->sk being set, and probably to an
  inet socket, not an arbitrary one.

  If we orphan the packet in ipvlan, then downstream things like FQ
  packet scheduler will not work properly.

  We need to change ip_defrag() to only use skb_orphan() when really
  needed, ie whenever frag_list is going to be used.

Eric suggested to stash sk in fragment queue and made an initial patch.
However there is a problem with this:

If skb is refragmented again right after, ip_do_fragment() will copy
head->sk to the new fragments, and sets up destructor to sock_wfree.
IOW, we have no choice but to fix up sk_wmem accouting to reflect the
fully reassembled skb, else wmem will underflow.

This change moves the orphan down into the core, to last possible moment.
As ip_defrag_offset is aliased with sk_buff->sk member, we must move the
offset into the FRAG_CB, else skb->sk gets clobbered.

This allows to delay the orphaning long enough to learn if the skb has
to be queued or if the skb is completing the reasm queue.

In the former case, things work as before, skb is orphaned.  This is
safe because skb gets queued/stolen and won't continue past reasm engine.

In the latter case, we will steal the skb->sk reference, reattach it to
the head skb, and fix up wmem accouting when inet_frag inflates truesize.

- The unimac may be put in a bad state if PHY RX clk doesn't exist
  during reset. Work around this by bringing the unimac out of reset
  during phy up.

- Remove redundant phy_{suspend/resume}

phy_{suspend/resume} is redundant. It gets called from phy_{stop/start}.

The unimac requires the PHY RX clk during reset or it may be put
into a bad state. Bring up the unimac after link up to ensure the
PHY RX clk exists.

On reworking and splitting the at803x driver, in splitting function of
at803x PHYs it was added a NULL dereference bug where priv is referenced
before it's actually allocated and then is tried to write to for the
is_1000basex and is_fiber variables in the case of at8031, writing on
the wrong address.

Fix this by correctly setting priv local variable only after
at803x_probe is called and actually allocates priv in the phydev struct.

====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

Patch #1 reject destroy chain command to delete device hooks in netdev
         family, hence, only delchain commands are allowed.

Patch #2 reject table flag update interference with netdev basechain
	 hook updates, this can leave hooks in inconsistent
	 registration/unregistration state.

Patch #3 do not unregister netdev basechain hooks if table is dormant.
	 Otherwise, splat with double unregistration is possible.

Patch #4 fixes Kconfig to allow to restore IP_NF_ARPTABLES,
	 from Kuniyuki Iwashima.

There are a more fixes still in progress on my side that need more work.

The SVA code checks that the PASID is valid for the device when assigning
the PASID to the MM, but the normal PAGING related path does not check it.

Devices that don't support PASID or PASID values too large for the device
should not invoke the driver callback. The drivers should rely on the
core code for this enforcement.

syzkaller started to report a warning below [0] after consuming the
commit 4654467d ("netfilter: arptables: allow xtables-nft only
builds").

The change accidentally removed the dependency on NETFILTER_FAMILY_ARP
from IP_NF_ARPTABLES.

If NF_TABLES_ARP is not enabled on Kconfig, NETFILTER_FAMILY_ARP will
be removed and some code necessary for arptables will not be compiled.

  $ grep -E "(NETFILTER_FAMILY_ARP|IP_NF_ARPTABLES|NF_TABLES_ARP)" .config
  CONFIG_NETFILTER_FAMILY_ARP=y
  # CONFIG_NF_TABLES_ARP is not set
  CONFIG_IP_NF_ARPTABLES=y

  $ make olddefconfig

  $ grep -E "(NETFILTER_FAMILY_ARP|IP_NF_ARPTABLES|NF_TABLES_ARP)" .config
  # CONFIG_NF_TABLES_ARP is not set
  CONFIG_IP_NF_ARPTABLES=y

So, when nf_register_net_hooks() is called for arptables, it will
trigger the splat below.

Now IP_NF_ARPTABLES is only enabled by IP_NF_ARPFILTER, so let's
restore the dependency on NETFILTER_FAMILY_ARP in IP_NF_ARPFILTER.
