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.

Char / Misc / Other smaller driver subsystem updates for 5.19-rc1
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 standard toolchain options to build with a system installed alsa-lib if we don't get anything from pkg-config.

net/ipv6: Expand and rename accept_unsolicited_na to accept_untracked_na
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.
- Add CXL _OSC support for claiming native control of CXL hotplug and

selftests: memcg: factor out common parts of memory.{low,min} tests
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.

selftests: memcg: fix compilation
Patch series "memcontrol selftests fixups", v2.
Flushing the patches to make memcontrol selftests check the events
behavior we had consensus about (test_memcg_low fails).
(test_memcg_reclaim, test_memcg_swap_max fail for me now but it's present
even before the refactoring.)
The two bigger changes are:
- adjustment of the protected values to make tests succeed with the given
tolerance,
- both test_memcg_low and test_memcg_min check protection of memory in
populated cgroups (actually as per Documentation/admin-guide/cgroup-v2.rst
memory.min should not apply to empty cgroups, which is not the case
currently. Therefore I unified tests with the populated case in order to to
bring more broken tests).
This patch (of 5):

selftests/net: enable lo.accept_local in psock_snd test
The psock_snd test sends and receives packets over loopback, and the test results depend on parameter settings: Set rp_filter=0, or set rp_filter=1 and accept_local=1 so that the test will pass. Otherwise, this test will fail with Resource temporarily unavailable: sudo ./psock_snd.sh dgram tx: 128 rx: 142 ./psock_snd: recv: Resource temporarily unavailable For most distro kernel releases(like Ubuntu or Centos), the parameter rp_filter is enabled by default, so it's necessary to enable the parameter lo.accept_local in psock_snd test. And this test runs inside a netns, changing a sysctl is fine.

sound updates for 5.19-rc1
Not much dramatic changes at this time, but we've received quite
a lot of changes for ASoC, while there are still a few fixes and
quirks for usual HD- and USB-auido. Here are some highlights.
* ASoC:
- Overhaul of endianness specification for data formats, avoiding
needless restrictions due to CODECs
- Initial stages of Intel AVS driver merge
- Introduction of v4 IPC mechanism for SOF
- TDM mode support for AK4613
- Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780
* Others
- A few regression fixes after the USB-audio endpoint management
refactoring
- More enhancements for Cirrus HD-audio codec support (still ongoing)
- Addition of generic serial MIDI driver

Networking changes for 5.19.
Core
----
- Support TCPv6 segmentation offload with super-segments larger than
64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).
- Generalize skb freeing deferral to per-cpu lists, instead of
per-socket lists.
- Add a netdev statistic for packets dropped due to L2 address
mismatch (rx_otherhost_dropped).
- Continue work annotating skb drop reasons.
- Accept alternative netdev names (ALT_IFNAME) in more netlink
requests.
- Add VLAN support for AF_PACKET SOCK_RAW GSO.
- Allow receiving skb mark from the socket as a cmsg.
- Enable memcg accounting for veth queues, sysctl tables and IPv6.
BPF
---
- Add libbpf support for User Statically-Defined Tracing (USDTs).
- Speed up symbol resolution for kprobes multi-link attachments.
- Support storing typed pointers to referenced and unreferenced
objects in BPF maps.
- Add support for BPF link iterator.
- Introduce access to remote CPU map elements in BPF per-cpu map.
- Allow middle-of-the-road settings for the
kernel.unprivileged_bpf_disabled sysctl.
- Implement basic types of dynamic pointers e.g. to allow for
dynamically sized ringbuf reservations without extra memory copies.
Protocols
---------
- Retire port only listening_hash table, add a second bind table
hashed by port and address. Avoid linear list walk when binding
to very popular ports (e.g. 443).
- Add bridge FDB bulk flush filtering support allowing user space
to remove all FDB entries matching a condition.
- Introduce accept_unsolicited_na sysctl for IPv6 to implement
router-side changes for RFC9131.
- Support for MPTCP path manager in user space.
- Add MPTCP support for fallback to regular TCP for connections
that have never connected additional subflows or transmitted
out-of-sequence data (partial support for RFC8684 fallback).

throughput.
- Support lockless operation of GRE tunnels with seq numbers enabled.
- WiFi support for host based BSS color collision detection.

linux-kselftest-kunit-5.19-rc1
This KUnit update for Linux 5.19-rc1 consists of several fixes, cleanups,
and enhancements to tests and framework:
- introduces _NULL and _NOT_NULL macros to pointer error checks
- reworks kunit_resource allocation policy to fix memory leaks when
caller doesn't specify free() function to be used when allocating
memory using kunit_add_resource() and kunit_alloc_resource() funcs.
- adds ability to specify suite-level init and exit functions

selftests: vm: check numa_available() before operating "merge_across_nodes" in ksm_tests
Patch series "selftests: vm: a few fixup patches". This series contains three fixup patches for vm selftests. They are independent. Please see the patches. This patch (of 3): Currently, ksm_tests operates "merge_across_nodes" with NUMA either enabled or disabled. In a system with NUMA disabled, these operations will fail and output a misleading report given "merge_across_nodes" does not exist in sysfs: ---------------------------- running ./ksm_tests -M -p 10 ---------------------------- f /sys/kernel/mm/ksm/merge_across_nodes fopen: No such file or directory Cannot save default tunables [FAIL] ---------------------- So check numa_available() before those operations to skip them if NUMA is disabled.

selftests: vm: add process_mrelease tests
Introduce process_mrelease syscall sanity tests which include tests which expect to fail: - process_mrelease with invalid pidfd and flags inputs - process_mrelease on a live process with no pending signals and valid process_mrelease usage which is expected to succeed. Because process_mrelease has to be used against a process with a pending SIGKILL, it's possible that the process exits before process_mrelease gets called. In such cases we retry the test with a victim that allocates twice more memory up to 1GB. This would require the victim process to spend more time during exit and process_mrelease has a better chance of catching the process before it exits and succeeding. On success the test reports the amount of memory the child had to allocate for reaping to succeed. Sample output: $ mrelease_test Success reaping a child with 1MB of memory allocations On failure the test reports the failure. Sample outputs: $ mrelease_test All process_mrelease attempts failed! $ mrelease_test process_mrelease: Invalid argument Link: https://lkml.kernel.org/r/20220518204316.13131-1-surenb@google.com Signed-off-by: Suren Baghdasaryan <surenb@google.com> Reviewed-by: Shuah Khan <skhan@linuxfoundation.org> Acked-by: Christian Brauner (Microsoft) <brauner@kernel.org> Reviewed-by: Muhammad Usama Anjum <usama.anjum@collabora.com> Cc: Michal Hocko <mhocko@suse.com> Cc: David Rientjes <rientjes@google.com> Cc: Matthew Wilcox (Oracle) <willy@infradead.org> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Roman Gushchin <guro@fb.com> Cc: Minchan Kim <minchan@kernel.org> Cc: "Kirill A .

selftests/bpf: fix btf_dump/btf_dump due to recent clang change
Latest llvm-project upstream had a change of behavior
related to qualifiers on function return type ([1]).
This caused selftests btf_dump/btf_dump failure.
The following example shows what changed.
$ cat t.c
typedef const char * const (* const (* const fn_ptr_arr2_t[5])())(char * (*)(int));
struct t {
int a;
fn_ptr_arr2_t l;
};
int foo(struct t *arg) {
return arg->a;
}
Compiled with latest upstream llvm15,
$ clang -O2 -g -target bpf -S -emit-llvm t.c
The related generated debuginfo IR looks like:
!16 = !DIDerivedType(tag: DW_TAG_typedef, name: "fn_ptr_arr2_t", file: !1, line: 1, baseType: !17)
!17 = !DICompositeType(tag: DW_TAG_array_type, baseType: !18, size: 320, elements: !32)
!18 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !19)
!19 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !20, size: 64)
!20 = !DISubroutineType(types: !21)
!21 = !{!22, null}
!22 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !23, size: 64)
!23 = !DISubroutineType(types: !24)
!24 = !{!25, !28}
!25 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !26, size: 64)
!26 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !27)
!27 = !DIBasicType(name: "char", size: 8, encoding: DW_ATE_signed_char)
You can see two intermediate const qualifier to pointer are dropped in debuginfo IR.
With llvm14, we have following debuginfo IR:
!16 = !DIDerivedType(tag: DW_TAG_typedef, name: "fn_ptr_arr2_t", file: !1, line: 1, baseType: !17)
!17 = !DICompositeType(tag: DW_TAG_array_type, baseType: !18, size: 320, elements: !34)
!18 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !19)
!19 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !20, size: 64)
!20 = !DISubroutineType(types: !21)
!21 = !{!22, null}
!22 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !23)
!23 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !24, size: 64)
!24 = !DISubroutineType(types: !25)
!25 = !{!26, !30}
!26 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !27)
!27 = !DIDerivedType(tag: DW_TAG_pointer_type, baseType: !28, size: 64)
!28 = !DIDerivedType(tag: DW_TAG_const_type, baseType: !29)
!29 = !DIBasicType(name: "char", size: 8, encoding: DW_ATE_signed_char)
All const qualifiers are preserved.
To adapt the selftest to both old and new llvm, this patch removed
the intermediate const qualifier in const-to-ptr types, to make the
test succeed again.
