Linus Torvalds 5e8379351d Including fixes from netfilter.
Current release - new code bugs:
 
  - clear msg_get_inq in __sys_recvfrom() and __copy_msghdr_from_user()
 
  - mptcp:
    - invoke MP_FAIL response only when needed
    - fix shutdown vs fallback race
    - consistent map handling on failure
 
  - octeon_ep: use bitwise AND
 
 Previous releases - regressions:
 
  - tipc: move bc link creation back to tipc_node_create, fix NPD
 
 Previous releases - always broken:
 
  - tcp: add a missing nf_reset_ct() in 3WHS handling, prevent socket
    buffered skbs from keeping refcount on the conntrack module
 
  - ipv6: take care of disable_policy when restoring routes
 
  - tun: make sure to always disable and unlink NAPI instances
 
  - phy: don't trigger state machine while in suspend
 
  - netfilter: nf_tables: avoid skb access on nf_stolen

 Misc:
 
  - ncsi: allow use of proper "mellanox" DT vendor prefix
 
  - act_api: add a message for user space if any actions were already
    flushed before the error was hit

Mat Martineau fd37c2ecb2 selftests: mptcp: Initialize variables to quiet gcc 12 warnings
In a few MPTCP selftest tools, gcc 12 complains that the 'sock' variable
might be used uninitialized. This is a false positive because the only
code path that could lead to uninitialized access is where getaddrinfo()
fails, but the local xgetaddrinfo() wrapper exits if such a failure
occurs.

Initialize the 'sock' variable anyway to allow the tools to build with
gcc 12.

Paolo Abeni 42fb6cddec selftests: mptcp: more stable diag tests
The mentioned test-case still use an hard-coded-len sleep to
wait for a relative large number of connection to be established.

On very slow VM and with debug build such timeout could be exceeded,
causing failures in our CI.

Address the issue polling for the expected condition several times,
up to an unreasonable high amount of time. On reasonably fast system
the self-tests will be faster then before, on very slow one we will
still catch the correct condition.

Raghavendra Rao Ananta 9e2f6498ef selftests: KVM: Handle compiler optimizations in ucall
The selftests, when built with newer versions of clang, is found
to have over optimized guests' ucall() function, and eliminating
the stores for uc.cmd (perhaps due to no immediate readers). This
resulted in the userspace side always reading a value of '0', and
causing multiple test failures.

As a result, prevent the compiler from optimizing the stores in
ucall() with WRITE_ONCE().

Riccardo Paolo Bestetti 313c502fa3 ipv4: fix bind address validity regression tests
Commit 8ff978b8b2 ("ipv4/raw: support binding to nonlocal addresses")
introduces support for binding to nonlocal addresses, as well as some
basic test coverage for some of the related cases.

Commit b4a028c4d0 ("ipv4: ping: fix bind address validity check")
fixes a regression which incorrectly removed some checks for bind
address validation. In addition, it introduces regression tests for
those specific checks. However, those regression tests are defective, in
that they perform the tests using an incorrect combination of bind
flags. As a result, those tests fail when they should succeed.

This commit introduces additional regression tests for nonlocal binding
and fixes the defective regression tests. It also introduces new
set_sysctl calls for the ipv4_bind test group, as to perform the ICMP
binding tests it is necessary to allow ICMP socket creation by setting
the net.ipv4.ping_group_range knob.

Riccardo Paolo Bestetti b4a028c4d0 ipv4: ping: fix bind address validity check
Commit 8ff978b8b2 ("ipv4/raw: support binding to nonlocal addresses")
introduced a helper function to fold duplicated validity checks of bind
addresses into inet_addr_valid_or_nonlocal(). However, this caused an
unintended regression in ping_check_bind_addr(), which previously would
reject binding to multicast and broadcast addresses, but now these are
both incorrectly allowed as reported in [1].

This patch restores the original check. A simple reordering is done to
improve readability and make it evident that multicast and broadcast
addresses should not be allowed. Also, add an early exit for INADDR_ANY
which replaces lost behavior added by commit 0ce779a9f5 ("net: Avoid
unnecessary inet_addr_type() call when addr is INADDR_ANY").

Furthermore, this patch introduces regression selftests to catch these
specific cases.

Jiri Olsa ad8848535e selftests/bpf: Shuffle cookies symbols in kprobe multi test
There's a kernel bug that causes cookies to be misplaced and
the reason we did not catch this with this test is that we
provide bpf_fentry_test* functions already sorted by name.

Shuffling function bpf_fentry_test2 deeper in the list and
keeping the current cookie values as before will trigger
the bug.

The kernel fix is coming in following changes.

Joel Savitz 9b4d5c01eb selftests: make use of GUP_TEST_FILE macro
Commit 17de1e559c ("selftests: clarify common error when running
gup_test") had most of its hunks dropped due to a conflict with another
patch accepted into Linux around the same time that implemented the same
behavior as a subset of other changes.

However, the remaining hunk defines the GUP_TEST_FILE macro without
making use of it. This patch makes use of the macro in the two relevant
places.

Furthermore, the above mentioned commit's log message erroneously describes
the changes that were dropped from the patch.

This patch corrects the record.

Mark Brown 795285ef24 selftests: Fix clang cross compilation
Unlike GCC clang uses a single compiler image to support multiple target
architectures meaning that we can't simply rely on CROSS_COMPILE to select
the output architecture. Instead we must pass --target to the compiler to
tell it what to output, kselftest was not doing this so cross compilation
of kselftest using clang resulted in kselftest being built for the host
architecture.

More work is required to fix tests using custom rules but this gets the
bulk of things building.

Merge tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random

Pull random number generator fixes from Jason Donenfeld:

 - A fix for a 5.19 regression for a case in which early device tree
   initializes the RNG, which flips a static branch.

   On most plaforms, jump labels aren't initialized until much later, so
   this caused splats. On a few mailing list threads, we cooked up easy
   fixes for arm64, arm32, and risc-v. But then things looked slightly
   more involved for xtensa, powerpc, arc, and mips. And at that point,
   when we're patching 7 architectures in a place before the console is
   even available, it seems like the cost/risk just wasn't worth it.

   So random.c works around it now by checking the already exported
   `static_key_initialized` boolean, as though somebody already ran into
   this issue in the past. I'm not super jazzed about that; it'd be
   prettier to not have to complicate downstream code. But I suppose
   it's practical.

 - A few small code nits and adding a missing __init annotation.

 - A change to the default config values to use the cpu and bootloader's

   This brings them into line with what all the distros do (Fedora/RHEL,
   Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at
   least), and moreover will now give us test coverage in various test
   beds that might have caught the above device tree bug earlier.

   around the RNG.

 - A documentation comment fix to unrelated maintainerless CRC code that
   I was asked to take, I guess because it has to do with polynomials
   (which the RNG thankfully no longer uses).

Jason A. Donenfeld 17b0128a13 wireguard: selftests: use maximum cpu features and allow rng seeding
By forcing the maximum CPU that QEMU has available, we expose additional
capabilities, such as the RNDR instruction, which increases test
coverage. This then allows the CI to skip the fake seeding step in some
cases. Also enable STRICT_KERNEL_RWX to catch issues related to early
jump labels when the RNG is initialized at boot.

David Matlack e0f3f46e42 KVM: selftests: Restrict test region to 48-bit physical addresses when using nested
The selftests nested code only supports 4-level paging at the moment.
This means it cannot map nested guest physical addresses with more than
48 bits. Allow perf_test_util nested mode to work on hosts with more
than 48 physical addresses by restricting the guest test region to
48-bits.

While here, opportunistically fix an off-by-one error when dealing with
vm_get_max_gfn(). perf_test_util.c was treating this as the maximum
number of GFNs, rather than the maximum allowed GFN. This didn't result
in any correctness issues, but it did end up shifting the test region
down slightly when using huge pages.

Add an option to dirty_log_perf_test that configures the vCPUs to run in
L2 instead of L1. This makes it possible to benchmark the dirty logging
performance of nested virtualization, which is particularly interesting
because KVM must shadow L1's EPT/NPT tables.

For now this support only works on x86_64 CPUs with VMX. Otherwise
passing -n results in the test being skipped.

David Matlack cdc979dae2 KVM: selftests: Link selftests directly with lib object files
The linker does obey strong/weak symbols when linking static libraries,
it simply resolves an undefined symbol to the first-encountered symbol.
This means that defining __weak arch-generic functions and then defining
arch-specific strong functions to override them in libkvm will not
always work.

More specifically, if we have:

lib/generic.c:

  void __weak foo(void)
  {
          pr_info("weak\n");
  }

  void bar(void)
  {
          foo();
  }

lib/x86_64/arch.c:

  void foo(void)
  {
          pr_info("strong\n");
  }

And a selftest that calls bar(), it will print "weak". Now if you make
generic.o explicitly depend on arch.o (e.g. add function to arch.c that
is called directly from generic.c) it will print "strong". In other
words, it seems that the linker is free to throw out arch.o when linking
because generic.o does not explicitly depend on it, which causes the
linker to lose the strong symbol.

One solution is to link libkvm.a with --whole-archive so that the linker
doesn't throw away object files it thinks are unnecessary. However that
is a bit difficult to plumb since we are using the common selftests
makefile rules. An easier solution is to drop libkvm.a just link
selftests with all the .o files that were originally in libkvm.a.

David Matlack 4ee602e78d KVM: selftests: Replace x86_page_size with PG_LEVEL_XX
x86_page_size is an enum used to communicate the desired page size with
which to map a range of memory. Under the hood they just encode the
desired level at which to map the page. This ends up being clunky in a
few ways:

 - The name suggests it encodes the size of the page rather than the
   level.
 - In other places in x86_64/processor.c we just use a raw int to encode
   the level.

Simplify this by adopting the kernel style of PG_LEVEL_XX enums and pass
around raw ints when referring to the level. This makes the code easier
to understand since these macros are very common in KVM MMU code.

Linus Torvalds 500a434fc5 Driver core changes for 5.19-rc1
Here is the set of driver core changes for 5.19-rc1.
 
 Note, I'm not really happy with this pull request as-is, see below for
 details, but overall this is all good for everything but a small set of
 systems, which we have a fix for already.
 
 Lots of tiny driver core changes and cleanups happened this cycle,
 but the two major things were:
 
 	- firmware_loader reorganization and additions including the
 	  ability to have XZ compressed firmware images and the ability
 	  for userspace to initiate the firmware load when it needs to,
 	  instead of being always initiated by the kernel. FPGA devices
 	  specifically want this ability to have their firmware changed
 	  over the lifetime of the system boot, and this allows them to
 	  work without having to come up with yet-another-custom-uapi
 	  interface for loading firmware for them.
 	- physical location support added to sysfs so that devices that
 	  know this information, can tell userspace where they are
 	  located in a common way.  Some ACPI devices already support
 	  this today, and more bus types should support this in the
 	  future.
 
 Smaller changes included:
 	- driver_override api cleanups and fixes
 	- error path cleanups and fixes
 	- get_abi script fixes
 	- deferred probe timeout changes.
 
 It's that last change that I'm the most worried about.  It has been
 reported to cause boot problems for a number of systems, and I have a
 tested patch series that resolves this issue.  But I didn't get it
 merged into my tree before 5.18-final came out, so it has not gotten any
 linux-next testing.
 
 I'll send the fixup patches (there are 2) as a follow-on series to this
 pull request if you want to take them directly, _OR_ I can just revert
 the probe timeout changes and they can wait for the next -rc1 merge
 cycle.  Given that the fixes are tested, and pretty simple, I'm leaning
 toward that choice.  Sorry this all came at the end of the merge window,
 I should have resolved this all 2 weeks ago, that's my fault as it was
 in the middle of some travel for me.
 
 All have been tested in linux-next for weeks, with no reported issues
 other than the above-mentioned boot time outs.
