Commit 8ff978b8b222 ("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 b4a028c4d031 ("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.

Commit 8ff978b8b222 ("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 0ce779a9f501 ("net: Avoid
unnecessary inet_addr_type() call when addr is INADDR_ANY").
Furthermore, this patch introduces regression selftests to catch these
specific cases.

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.

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
seeds for initializing the RNG earlier.
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.
- A change to WireGuard CI's configuration to increase test coverage
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).
* tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random:
wireguard: selftests: use maximum cpu features and allow rng seeding
random: remove rng_has_arch_random()
random: credit cpu and bootloader seeds by default
random: do not use jump labels before they are initialized
random: account for arch randomness in bits
random: mark bootloader randomness code as __init
random: avoid checking crng_ready() twice in random_init()
crc-itu-t: fix typo in CRC ITU-T polynomial comment
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.

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.

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.

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

hyperv_clock doesn't always give a stable test result, especially with
AMD CPUs. The test compares Hyper-V MSR clocksource (acquired either
with rdmsr() from within the guest or KVM_GET_MSRS from the host)
against rdtsc(). To increase the accuracy, increase the measured delay
(done with nop loop) by two orders of magnitude and take the mean rdtsc()
value before and after rdmsr()/KVM_GET_MSRS.

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.

Here is the large set of char, misc, and other driver subsystem updates
for 5.19-rc1. The merge request for this has been delayed as I wanted
to get lots of linux-next testing due to some late arrivals of changes
for the habannalabs driver.
Highlights of this merge are:
- habanalabs driver updates for new hardware types and fixes and
other updates
- IIO driver tree merge which includes loads of new IIO drivers
and cleanups and additions
- PHY driver tree merge with new drivers and small updates to
existing ones
- interconnect driver tree merge with fixes and updates
- soundwire driver tree merge with some small fixes
- coresight driver tree merge with small fixes and updates
- mhi bus driver tree merge with lots of updates and new device
support
- firmware driver updates
- fpga driver updates
- lkdtm driver updates (with a merge conflict, more on that
below)
- extcon driver tree merge with small updates
- lots of other tiny driver updates and fixes and cleanups, full
details in the shortlog.
All of these have been in linux-next for almost 2 weeks with no reported
problems.
Note, there are 3 merge conflicts when merging this with your tree:
- MAINTAINERS, should be easy to resolve
- drivers/slimbus/qcom-ctrl.c, should be straightforward
resolution
- drivers/misc/lkdtm/stackleak.c, not an easy resolution. This
has been noted in the linux-next tree for a while, and
resolved there, here's a link to the resolution that Stephen
came up with and that Kees says is correct:
https://lore.kernel.org/r/20220509185344.3fe1a354@canb.auug.org.au
I will be glad to provide a merge point that contains these resolutions
if that makes things any easier for you.

Follow the pattern used by other selftests like memfd and fall back on the

there is a need for it.

RFC 9131 changes default behaviour of handling RX of NA messages when the
corresponding entry is absent in the neighbour cache. The current
implementation is limited to accept just unsolicited NAs. However, the
RFC is more generic where it also accepts solicited NAs. Both types
should result in adding a STALE entry for this case.
Expand accept_untracked_na behaviour to also accept solicited NAs to
be compliant with the RFC and rename the sysctl knob to
accept_untracked_na.

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for this cycle.
The highlight is new driver-core infrastructure and CXL subsystem
changes for allowing lockdep to validate device_lock() usage. Thanks
to PeterZ for setting me straight on the current capabilities of the
lockdep API, and Greg acked it as well.
On the CXL ACPI side this update adds support for CXL _OSC so that
platform firmware knows that it is safe to still grant Linux native
control of PCIe hotplug and error handling in the presence of CXL
devices. A circular dependency problem was discovered between suspend
and CXL memory for cases where the suspend image might be stored in
CXL memory where that image also contains the PCI register state to
restore to re-enable the device. Disable suspend for now until an
architecture is defined to clarify that conflict.
Lastly a collection of reworks, fixes, and cleanups to the CXL
subsystem where support for snooping mailbox commands and properly
handling the "mem_enable" flow are the highlights.
Summary:
- Add driver-core infrastructure for lockdep validation of
device_lock(), and fixup a deadlock report that was previously
hidden behind the 'lockdep no validate' policy.

The memory protection test setup and runtime is almost equal for
memory.low and memory.min cases.
It makes modification of the common parts prone to mistakes, since the
protections are similar not only in setup but also in principle, factor
the common part out.
Past exceptions between the tests:
- missing memory.min is fine (kept),
- test_memcg_low protected orphaned pagecache (adapted like
test_memcg_min and we keep the processes of protected memory running).
The evaluation in two tests is different (OOM of allocator vs low events
of protégés), this is kept different.

The reclaim is triggered by memory limit in a subtree, therefore the
testcase does not need configured protection against external reclaim.
Also, correct respective comments.

The numbers are not easy to derive in a closed form (certainly mere
protections ratios do not apply), therefore use a simulation to obtain
expected numbers.

This is effectively a revert of commit cdc69458a5f3 ("cgroup: account for
memory_recursiveprot in test_memcg_low()"). The case test_memcg_low will
fail with memory_recursiveprot until resolved in reclaim code.
However, this patch preserves the existing helpers and variables for later
uses.
