[PATCH v2] kunit: Cover 'assert.c' with tests
by Ivan Orlov
There are multiple assertion formatting functions in the `assert.c`
file, which are not covered with tests yet. Implement the KUnit test
for these functions.
The test consists of 11 test cases for the following functions:
1) 'is_literal'
2) 'is_str_literal'
3) 'kunit_assert_prologue', test case for multiple assert types
4) 'kunit_assert_print_msg'
5) 'kunit_unary_assert_format'
6) 'kunit_ptr_not_err_assert_format'
7) 'kunit_binary_assert_format'
8) 'kunit_binary_ptr_assert_format'
9) 'kunit_binary_str_assert_format'
10) 'kunit_assert_hexdump'
11) 'kunit_mem_assert_format'
The test aims at maximizing the branch coverage for the assertion
formatting functions.
As you can see, it covers some of the static helper functions as
well, so mark the static functions in `assert.c` as 'VISIBLE_IF_KUNIT'
and conditionally export them with EXPORT_SYMBOL_IF_KUNIT. Add the
corresponding definitions to `assert.h`.
Build the assert test when CONFIG_KUNIT_TEST is enabled, similar to
how it is done for the string stream test.

V1 -> V2:
- Check the output from the string stream for containing the key parts
instead of comparing the results with expected strings char by char, as
it was suggested by Rae Moar <rmoar(a)google.com>. Define two macros to
make it possible (ASSERT_TEST_EXPECT_CONTAIN and
ASSERT_TEST_EXPECT_NCONTAIN).
- Mark the static functions in `assert.c` as VISIBLE_IF_KUNIT and export
them conditionally if kunit is enabled instead of including the
`assert_test.c` file in the end of `assert.c`. This way we will decouple
the test from the implementation (SUT).
- Update the kunit_assert_hexdump test: now it checks for presense of
the brackets '<>' around the non-matching bytes, instead of comparing
the kunit_assert_hexdump output char by char.

[RFC PATCH net-next v8 00/14] Device Memory TCP
by Mina Almasry
RFC v8:
=======
Major Changes:
--------------
- Fixed build error generated by patch-by-patch build.
- Applied docs suggestions from Randy.
RFC v7:
=======
Major Changes:
--------------
This revision largely rebases on top of net-next and addresses the feedback
RFCv6 received from folks, namely Jakub, Yunsheng, Arnd, David, & Pavel.
The series remains in RFC because the queue-API ndos defined in this
series are not yet implemented. I have a GVE implementation I carry out
of tree for my testing. A upstreamable GVE implementation is in the
works. Aside from that, in my estimation all the patches are ready for
review/merge. Please do take a look.
As usual the full devmem TCP changes including the full GVE driver
implementation is here:

Perf - page-pool benchmark:
---------------------------
Improved performance of bench_page_pool_simple.ko tests compared to v6:
https://pastebin.com/raw/v5dYRg8L
net-next base: 8 cycle fast path.
RFC v6: 10 cycle fast path.
RFC v7: 9 cycle fast path.
RFC v7 with CONFIG_DMA_SHARED_BUFFER disabled: 8 cycle fast path,
same as baseline.
Perf - Devmem TCP benchmark:
---------------------
Perf is about the same regardless of the changes in v7, namely the
removal of the static_branch_unlikely to improve the page_pool benchmark
performance:
189/200gbps bi-directional throughput with RX devmem TCP and regular TCP
TX i.e. ~95% line rate.
RFC v6:
=======
Major Changes:
--------------
This revision largely rebases on top of net-next and addresses the little
feedback RFCv5 received.
The series remains in RFC because the queue-API ndos defined in this
series are not yet implemented. I have a GVE implementation I carry out
of tree for my testing. A upstreamable GVE implementation is in the
works. Aside from that, in my estimation all the patches are ready for
review/merge. Please do take a look.
As usual the full devmem TCP changes including the full GVE driver
implementation is here:
https://github.com/mina/linux/commits/tcpdevmem-v6/
This version also comes with some performance data recorded in the cover
letter (see below changelog).
Detailed changelog:
- Rebased on top of the merged netmem_ref changes.
- Converted skb->dmabuf to skb->readable (Pavel). Pavel's original
suggestion was to remove the skb->dmabuf flag entirely, but when I
looked into it closely, I found the issue that if we remove the flag
we have to dereference the shinfo(skb) pointer to obtain the first
frag to tell whether an skb is readable or not. This can cause a
performance regression if it dirties the cache line when the
shinfo(skb) was not really needed. Instead, I converted the skb->dmabuf
flag into a generic skb->readable flag which can be re-used by io_uring
0-copy RX.
- Squashed a few locking optimizations from Eric Dumazet in the RX path
and the DEVMEM_DONTNEED setsockopt.
- Expanded the tests a bit. Added validation for invalid scenarios and
added some more coverage.
Perf - page-pool benchmark:
---------------------------
bench_page_pool_simple.ko tests with and without these changes:
https://pastebin.com/raw/ncHDwAbn
AFAIK the number that really matters in the perf tests is the
'tasklet_page_pool01_fast_path Per elem'. This one measures at about 8
cycles without the changes but there is some 1 cycle noise in some
results.
With the patches this regresses to 9 cycles with the changes but there
is 1 cycle noise occasionally running this test repeatedly.
Lastly I tried disable the static_branch_unlikely() in
netmem_is_net_iov() check. To my surprise disabling the
static_branch_unlikely() check reduces the fast path back to 8 cycles,
but the 1 cycle noise remains.
Perf - Devmem TCP benchmark:
---------------------
189/200gbps bi-directional throughput with RX devmem TCP and regular TCP
TX i.e. ~95% line rate.
Major changes in RFC v5:
========================
1. Rebased on top of 'Abstract page from net stack' series and used the
new netmem type to refer to LSB set pointers instead of re-using
struct page.
2. Downgraded this series back to RFC and called it RFC v5. This is
because this series is now dependent on 'Abstract page from net
stack'[1] and the queue API. Both are removed from the series to
reduce the patch # and those bits are fairly independent or
pre-requisite work.
3. Reworked the page_pool devmem support to use netmem and for some
more unified handling.
4. Reworked the reference counting of net_iov (renamed from
page_pool_iov) to use pp_ref_count for refcounting.
The full changes including the dependent series and GVE page pool
support is here:
https://github.com/mina/linux/commits/tcpdevmem-rfcv5/
[1] https://patchwork.kernel.org/project/netdevbpf/list/?series=810774
Major changes in v1:
====================
1. Implemented MVP queue API ndos to remove the userspace-visible
driver reset.
2. Fixed issues in the napi_pp_put_page() devmem frag unref path.
3. Removed RFC tag.
Many smaller addressed comments across all the patches (patches have
individual change log).
Full tree including the rest of the GVE driver changes:
https://github.com/mina/linux/commits/tcpdevmem-v1
Changes in RFC v3:
==================
1. Pulled in the memory-provider dependency from Jakub's RFC[1] to make the
series reviewable and mergeable.
2. Implemented multi-rx-queue binding which was a todo in v2.
3. Fix to cmsg handling.
The sticking point in RFC v2[2] was the device reset required to refill
the device rx-queues after the dmabuf bind/unbind. The solution
suggested as I understand is a subset of the per-queue management ops
Jakub suggested or similar:
https://lore.kernel.org/netdev/20230815171638.4c057dcd@kernel.org/
This is not addressed in this revision, because:
1. This point was discussed at netconf & netdev and there is openness to
using the current approach of requiring a device reset.
2. Implementing individual queue resetting seems to be difficult for my
test bed with GVE. My prototype to test this ran into issues with the
rx-queues not coming back up properly if reset individually. At the
moment I'm unsure if it's a mistake in the POC or a genuine issue in
the virtualization stack behind GVE, which currently doesn't test
individual rx-queue restart.
3. Our usecases are not bothered by requiring a device reset to refill
the buffer queues, and we'd like to support NICs that run into this
limitation with resetting individual queues.
My thought is that drivers that have trouble with per-queue configs can
use the support in this series, while drivers that support new netdev
ops to reset individual queues can automatically reset the queue as
part of the dma-buf bind/unbind.
The same approach with device resets is presented again for consideration
with other sticking points addressed.
This proposal includes the rx devmem path only proposed for merge. For a
snapshot of my entire tree which includes the GVE POC page pool support &
device memory support:

Changes in RFC v2:
==================
The sticking point in RFC v1[1] was the dma-buf pages approach we used to
deliver the device memory to the TCP stack. RFC v2 is a proof-of-concept
that attempts to resolve this by implementing scatterlist support in the
networking stack, such that we can import the dma-buf scatterlist
directly. This is the approach proposed at a high level here[2].
Detailed changes:
1. Replaced dma-buf pages approach with importing scatterlist into the
page pool.
2. Replace the dma-buf pages centric API with a netlink API.
3. Removed the TX path implementation - there is no issue with
implementing the TX path with scatterlist approach, but leaving
out the TX path makes it easier to review.
4. Functionality is tested with this proposal, but I have not conducted
perf testing yet. I'm not sure there are regressions, but I removed
perf claims from the cover letter until they can be re-confirmed.
5. Added Signed-off-by: contributors to the implementation.
6. Fixed some bugs with the RX path since RFC v1.
Any feedback welcome, but specifically the biggest pending questions
needing feedback IMO are:
1. Feedback on the scatterlist-based approach in general.
2. Netlink API (Patch 1 & 2).
3. Approach to handle all the drivers that expect to receive pages from
the page pool (Patch 6).

==================
* TL;DR:
Device memory TCP (devmem TCP) is a proposal for transferring data to and/or
from device memory efficiently, without bouncing the data to a host memory
buffer.
* Problem:
A large amount of data transfers have device memory as the source and/or
destination. Accelerators drastically increased the volume of such transfers.
Some examples include:
- ML accelerators transferring large amounts of training data from storage into
GPU/TPU memory. In some cases ML training setup time can be as long as 50% of
TPU compute time, improving data transfer throughput & efficiency can help
improving GPU/TPU utilization.
- Distributed training, where ML accelerators, such as GPUs on different hosts,
exchange data among them.
- Distributed raw block storage applications transfer large amounts of data with
remote SSDs, much of this data does not require host processing.
Today, the majority of the Device-to-Device data transfers the network are
implemented as the following low level operations: Device-to-Host copy,
Host-to-Host network transfer, and Host-to-Device copy.
The implementation is suboptimal, especially for bulk data transfers, and can
put significant strains on system resources, such as host memory bandwidth,
PCIe bandwidth, etc. One important reason behind the current state is the
kernel’s lack of semantics to express device to network transfers.
* Proposal:
In this patch series we attempt to optimize this use case by implementing
socket APIs that enable the user to:
1. send device memory across the network directly, and
2. receive incoming network packets directly into device memory.
Packet _payloads_ go directly from the NIC to device memory for receive and from
device memory to NIC for transmit.
Packet _headers_ go to/from host memory and are processed by the TCP/IP stack
normally. The NIC _must_ support header split to achieve this.
Advantages:
- Alleviate host memory bandwidth pressure, compared to existing
network-transfer + device-copy semantics.
- Alleviate PCIe BW pressure, by limiting data transfer to the lowest level
of the PCIe tree, compared to traditional path which sends data through the
root complex.
* Patch overview:
** Part 1: netlink API
Gives user ability to bind dma-buf to an RX queue.
** Part 2: scatterlist support
Currently the standard for device memory sharing is DMABUF, which doesn't
generate struct pages. On the other hand, networking stack (skbs, drivers, and
page pool) operate on pages. We have 2 options:
1. Generate struct pages for dmabuf device memory, or,
2. Modify the networking stack to process scatterlist.
Approach #1 was attempted in RFC v1. RFC v2 implements approach #2.
** part 3: page pool support
We piggy back on page pool memory providers proposal:
https://github.com/kuba-moo/linux/tree/pp-providers
It allows the page pool to define a memory provider that provides the
page allocation and freeing. It helps abstract most of the device memory
TCP changes from the driver.
** part 4: support for unreadable skb frags
Page pool iovs are not accessible by the host; we implement changes
throughput the networking stack to correctly handle skbs with unreadable
frags.
** Part 5: recvmsg() APIs
We define user APIs for the user to send and receive device memory.
Not included with this series is the GVE devmem TCP support, just to
simplify the review. Code available here if desired:
https://github.com/mina/linux/tree/tcpdevmem
This series is built on top of net-next with Jakub's pp-providers changes
cherry-picked.
* NIC dependencies:
1. (strict) Devmem TCP require the NIC to support header split, i.e. the
capability to split incoming packets into a header + payload and to put
each into a separate buffer. Devmem TCP works by using device memory
for the packet payload, and host memory for the packet headers.
2. (optional) Devmem TCP works better with flow steering support & RSS support,
i.e. the NIC's ability to steer flows into certain rx queues. This allows the
sysadmin to enable devmem TCP on a subset of the rx queues, and steer
devmem TCP traffic onto these queues and non devmem TCP elsewhere.
The NIC I have access to with these properties is the GVE with DQO support
running in Google Cloud, but any NIC that supports these features would suffice.
I may be able to help reviewers bring up devmem TCP on their NICs.
* Testing:
The series includes a udmabuf kselftest that show a simple use case of
devmem TCP and validates the entire data path end to end without
a dependency on a specific dmabuf provider.
** Test Setup
Kernel: net-next with this series and memory provider API cherry-picked
locally.
Hardware: Google Cloud A3 VMs.
NIC: GVE with header split & RSS & flow steering support.

[PATCH net-next v3] selftests: drv-net: add checksum tests
by Willem de Bruijn
From: Willem de Bruijn <willemb(a)google.com>
Run tools/testing/selftest/net/csum.c as part of drv-net.
This binary covers multiple scenarios, based on arguments given,
for both IPv4 and IPv6:
- Accept UDP correct checksum
- Detect UDP invalid checksum
- Accept TCP correct checksum
- Detect TCP invalid checksum
- Transmit UDP: basic checksum offload
- Transmit UDP: zero checksum conversion
The test direction is reversed between receive and transmit tests, so
that the NIC under test is always the local machine.
In total this adds up to 12 testcases, with more to follow. For
conciseness, I replaced individual functions with a function factory.
Also detect hardware offload feature availability using Ethtool
netlink and skip tests when either feature is off. This need may be
common for offload feature tests and eventually deserving of a thin
wrapper in lib.py.
Missing are the PF_PACKET based send tests ('-P'). These use
virtio_net_hdr to program hardware checksum offload. Which requires
looking up the local MAC address and (harder) the MAC of the next hop.
I'll have to give it some though how to do that robustly and where
that code would belong.
Tested:
make -C tools/testing/selftests/ \
TARGETS="drivers/net drivers/net/hw" \
install INSTALL_PATH=/tmp/ksft
cd /tmp/ksft

[PATCH v4] selftests/resctrl: fix clang build warnings related to abs(), labs() calls
by John Hubbard
When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...two types of warnings occur:
warning: absolute value function 'abs' given an argument of type
'long' but has parameter of type 'int' which may cause truncation of
value
warning: taking the absolute value of unsigned type 'unsigned long'
has no effect
Fix these by:
a) using labs() in place of abs(), when long integers are involved, and
b) Change to use signed integer data types, in places where subtraction
is used (and could end up with negative values).
c) Remove a duplicate abs() call in cmt_test.c.

[PATCH] selftests/netfilter: formally SKIP() two cases of setup failure
by John Hubbard
If mnl_socket_open() or mnl_socket_bind() fails, it's generally due to
not having the user space parts fully installed and configured
correctly. This was previously ignored and reported as a test PASS, but
what really happened is that the tests were being skipped. This led to
generating inaccurate TAP output (I've omitted the leading '#'
character):
Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0
Fix this by using kselftest's SKIP() macro. The new output on the same
misconfigured system shows:
Totals: pass:0 fail:0 xfail:0 xpass:0 skip:3 error:0
This was briefly discussed already with Felix Huettner [1].

[PATCH AUTOSEL 6.8 18/52] KVM: selftests: Add test for uaccesses to non-existent vgic-v2 CPUIF
by Sasha Levin
From: Oliver Upton <oliver.upton(a)linux.dev>
[ Upstream commit 160933e330f4c5a13931d725a4d952a4b9aefa71 ]
Assert that accesses to a non-existent vgic-v2 CPU interface
consistently fail across the various KVM device attr ioctls. This also
serves as a regression test for a bug wherein KVM hits a NULL
dereference when the CPUID specified in the ioctl is invalid.
Note that there is no need to print the observed errno, as TEST_ASSERT()
will take care of it.

[PATCH v2] selftests/resctrl: fix clang build warnings related to abs(), labs() calls
by John Hubbard
First of all, in order to build with clang at all, one must first apply
Valentin Obst's build fix for LLVM [1]. Furthermore, for this particular
resctrl directory, my pending fix [2] must also be applied. Once those
fixes are in place, then when building with clang, via:
make LLVM=1 -C tools/testing/selftests
...two types of warnings occur:
warning: absolute value function 'abs' given an argument of type
'long' but has parameter of type 'int' which may cause truncation of
value
warning: taking the absolute value of unsigned type 'unsigned long'
has no effect
Fix these by:
a) using labs() in place of abs(), when long integers are involved, and
b) Change to use signed integer data types, in places where subtraction
is used (and could end up with negative values).

Hi Reinette,
This v2 includes a fix for the bugs that you pointed out (thanks!) in v1.
I kept the changes to signed integers minimal: only what is required in
order to get a clean clang build.
thanks,
John Hubbard

[PATCH net-next v3] selftest: epoll_busy_poll: epoll busy poll tests
by Joe Damato
Add a simple test for the epoll busy poll ioctls, using the kernel
selftest harness.
This test ensures that the ioctls have the expected return codes and
that the kernel properly gets and sets epoll busy poll parameters.
The test can be expanded in the future to do real busy polling (provided
another machine to act as the client is available).
Signed-off-by: Joe Damato <jdamato(a)fastly.com>
---
v2 -> v3:
- Added this changelog :)
- Add libcap to LDLIBS.
- Most other changes are in test_set_invalid:
- Check if CAP_NET_ADMIN is set in the effective set before setting
busy_poll_budget over NAPI_POLL_WEIGHT. The test which follows
assumes CAP_NET_ADMIN.
- Drop CAP_NET_ADMIN from effective set in order to ensure the ioctl
fails when busy_poll_budget exceeds NAPI_POLL_WEIGHT.
- Put CAP_NET_ADMIN back into the effective set afterwards.
- Changed self->params.busy_poll_budget from 65535 to UINT16_MAX.
- Changed the cast for params.busy_poll_usecs from unsigned int to
uint32_t in the test_set_invalid case.
v1 -> v2:
- Rewrote completely to use kernel self test harness.

[PATCH bpf-next] bpf, arm64: Add support for lse atomics in bpf_arena
by Puranjay Mohan
When LSE atomics are available, BPF atomic instructions are implemented
as single ARM64 atomic instructions, therefore it is easy to enable
these in bpf_arena using the currently available exception handling
setup.
LL_SC atomics use loops and therefore would need more work to enable in
bpf_arena.
Enable LSE atomics based instructions in bpf_arena and use the
bpf_jit_supports_insn() callback to reject atomics in bpf_arena if LSE
atomics are not available.
All atomics and arena_atomics selftests are passing:

[PATCH v5 8/8] selftests/pcie_bwctrl: Create selftests
by Ilpo Järvinen
Create selftests for PCIe BW control through the PCIe cooling device
sysfs interface.
First, the BW control selftest finds the PCIe Port to test with. By
default, the PCIe Port with the highest Link Speed is selected but
another PCIe Port can be provided with -d parameter.
The actual test steps the cur_state of the cooling device one-by-one
from max_state to what the cur_state was initially. The speed change
is confirmed by observing the current_link_speed for the corresponding
PCIe Port.

[PATCH] selftests/mqueue: fix 5 warnings about signed/unsigned mismatches
by John Hubbard
When building with clang, via:
make LLVM=1 -C tools/testing/selftest
...clang warns about several cases of using a signed integer for the
priority argument to mq_receive(3), which expects an unsigned int.
Fix this by declaring the type as unsigned int in all cases.

Add several new test cases which assert corner cases on the eventfd
mechanism, for example, the supplied buffer is less than 8 bytes,
attempting to write a value that is too large, etc.

[PATCH v2] selftests/net: fix uninitialized variables
by John Hubbard
When building with clang, via:
make LLVM=1 -C tools/testing/selftest
...clang warns about three variables that are not initialized in all
cases:
1) The opt_ipproto_off variable is used uninitialized if "testname" is
not "ip". Willem de Bruijn pointed out that this is an actual bug, and
suggested the fix that I'm using here (thanks!).
2) The addr_len is used uninitialized, but only in the assert case,
which bails out, so this is harmless.
3) The family variable in add_listener() is only used uninitialized in
the error case (neither IPv4 nor IPv6 is specified), so it's also
harmless.
Fix by initializing each variable.

[PATCH AUTOSEL 6.6 15/43] KVM: selftests: Add test for uaccesses to non-existent vgic-v2 CPUIF
by Sasha Levin
From: Oliver Upton <oliver.upton(a)linux.dev>
[ Upstream commit 160933e330f4c5a13931d725a4d952a4b9aefa71 ]
Assert that accesses to a non-existent vgic-v2 CPU interface
consistently fail across the various KVM device attr ioctls. This also
serves as a regression test for a bug wherein KVM hits a NULL
dereference when the CPUID specified in the ioctl is invalid.
Note that there is no need to print the observed errno, as TEST_ASSERT()
will take care of it.

[PATCH AUTOSEL 5.15 5/5] selftests: sud_test: return correct emulated syscall value on RISC-V
by Sasha Levin
From: Clément Léger <cleger(a)rivosinc.com>
[ Upstream commit 17c67ed752d6a456602b3dbb25c5ae4d3de5deab ]
Currently, the sud_test expects the emulated syscall to return the
emulated syscall number. This assumption only works on architectures
were the syscall calling convention use the same register for syscall
number/syscall return value. This is not the case for RISC-V and thus
the return value must be also emulated using the provided ucontext.

[PATCH AUTOSEL 6.6 18/19] selftests: sud_test: return correct emulated syscall value on RISC-V
by Sasha Levin
From: Clément Léger <cleger(a)rivosinc.com>
[ Upstream commit 17c67ed752d6a456602b3dbb25c5ae4d3de5deab ]
Currently, the sud_test expects the emulated syscall to return the
emulated syscall number. This assumption only works on architectures
were the syscall calling convention use the same register for syscall
number/syscall return value. This is not the case for RISC-V and thus
the return value must be also emulated using the provided ucontext.

[BUG selftests/pidfd] pidfd_setns_test HANG
by Mirsad Todorovac
Hi, all,
With the latest 6.9-rc7 torvalds tree kernel, the "make kselftest"
always hangs in the following
./pidfd_setns_test.
Symptoms are that all ./pidfd_netne_test processes end up in pause()
syscalls, with
nothing to wake them up.
Please find the config attached. All the options from the
selftests/pidfdconfig are on (verified):
CONFIG_UTS_NS=y
CONFIG_IPC_NS=y
CONFIG_USER_NS=y
CONFIG_PID_NS=y
CONFIG_NET_NS=y
CONFIG_CGROUPS=y
CONFIG_CHECKPOINT_RESTORE=y

[PATCH net-next v8 0/3] net: gro: remove network_header use, move p->{flush/flush_id} calculations to L4
by Richard Gobert
The cb fields network_offset and inner_network_offset are used instead of
skb->network_header throughout GRO.
These fields are then leveraged in the next commit to remove flush_id state
from napi_gro_cb, and stateful code in {ipv6,inet}_gro_receive which may be
unnecessarily complicated due to encapsulation support in GRO. These fields
are checked in L4 instead.
3rd patch adds tests for different flush_id flows in GRO.

[PATCH v6 00/10] Fix Kselftest's vfork() side effects
by Mickaël Salaün
Hi,
This sixth series just update the last patch description.
Shuah, I think this should be in -next really soon to make sure
everything works fine for the v6.9 release, which is not currently the
case. I cannot test against all kselftests though. I would prefer to
let you handle this, but I guess you're not able to do so and I'll push
it on my branch without reply from you. Even if I push it on my branch,
please push it on yours too as soon as you see this and I'll remove it
from mine.
Mark, Jakub, could you please test this series?
As reported by Kernel Test Robot [1] and Sean Christopherson [2], some
tests fail since v6.9-rc1 . This is due to the use of vfork() which
introduced some side effects. Similarly, while making it more generic,
a previous commit made some Landlock file system tests flaky, and
subject to the host's file system mount configuration.
This series fixes all these side effects by replacing vfork() with
clone3() and CLONE_VFORK, which is cleaner (no arbitrary shared memory)
and makes the Kselftest framework more robust.
I tried different approaches and I found this one to be the cleaner and
less invasive for current test cases.
I successfully ran the following tests (using TEST_F and
fork/clone/clone3, and KVM_ONE_VCPU_TEST) with this series:
- kvm:fix_hypercall_test
- kvm:sync_regs_test
- kvm:userspace_msr_exit_test
- kvm:vmx_pmu_caps_test
- landlock:fs_test
- landlock:net_test
- landlock:ptrace_test
- move_mount_set_group:move_mount_set_group_test

- perf_events:remove_on_exec
- pidfd:pidfd_getfd_test
- pidfd:pidfd_setns_test
- seccomp:seccomp_bpf
- user_events:abi_test

[PATCH 00/18] HID: Include current HID-BPF fixes in tree
by Benjamin Tissoires
When I introduced HID-BPF, I mentioned that we should ship the HID-BPF
programs in the kernel when they are fixes so that everybody can benefit
from them.
I tried multiple times to do so but I was confronted to a tough problem:
how can I make the kernel load them automatically?
I went over a few solutions, but it always came down to something either
ugly, or either not satisfying (like forcing `bpftool` to be compiled
first, or not being able to insert them as a module).
OTOH, I was working with Peter on `udev-hid-bpf`[0] as a proof of
concept on how a minimal loader should look like. This allowed me to
experiment on the BPF files and how they should look like.
And after further thoughts, I realized that `udev-hid-bpf` could very
well be the `kmod load` that we currently have:
- the kernel handles the device normally
- a udev event is emitted
- a udev rule fires `udev-hid-bpf` and load the appropriate HID-BPF
file(s) based on the modalias
Given that most HID devices are supposed to work to a minimal level when
connected without any driver, this makes the whole HID-BPF programs nice
to have but not critical. We can then postpone the HID-BPF loading when
userspace is ready.
Working with HID-BPF is also a much better user experience for end users
(as I predicted). All they have to do is to go to the `udev-hid-bpf`
project, fetch an artifact from the MR that concerns them, run
`install.sh` (no compilation required), and their devices are fixed
(minus some back and forth when the HID-BPF program needs some changes).
So I already have that loader available, and it works well enough for
our users. But the missing point was still how to "upstream" those BPF
fixes?
That's where this patch series comes in: we simply store the fixes in
the kernel under `drivers/hid/bpf/progs`, provide a way to compile them,
but also add tests for them in the selftests dir.
Once a program is accepted here, for convenience, the same program will
move from a "testing" directory to a "stable" directory on
`udev-hid-bpf`. This way, distributions don't need to follow when there
is a new program added here, they can just ship the "stable" ones from
`udev-hid-bpf`.

[PATCH net-next v3 0/2] fix icmp error source address over xfrm tunnel
by Antony Antony
Hi,
This fix, originally intended for XFRM/IPsec, has been recommended by
Steffen Klassert to submit to the net tree.
The patch addresses a minor issue related to the IPv4 source address of
ICMP error messages, which originated from an old 2011 commit:
415b3334a21a ("icmp: Fix regression in nexthop resolution during replies.")
The omission of a "Fixes" tag in the following commit is deliberate
to prevent potential test failures and subsequent regression issues
that may arise from backporting this patch all stable kerenels.
This is a minor fix, anot not security fix.
With a seleftest I am submitting this to net-next tree.
v2->v3 : fix testscript. The IFS, space, got mangled.
v1->v2 : add kernel selftest script

[PATCH net] selftests/bpf: fix pointer arithmetic in test_xdp_do_redirect
by Michal Schmidt
Cast operation has a higher precedence than addition. The code here
wants to zero the 2nd half of the 64-bit metadata, but due to a pointer
arithmetic mistake, it writes the zero at offset 16 instead.
Just adding parentheses around "data + 4" would fix this, but I think
this will be slightly better readable with array syntax.
I was unable to test this with tools/testing/selftests/bpf/vmtest.sh,
because my glibc is newer than glibc in the provided VM image.
So I just checked the difference in the compiled code.
objdump -S tools/testing/selftests/bpf/xdp_do_redirect.test.o:

[PATCH bpf-next v4 0/3] export send_recv_data
by Geliang Tang
From: Geliang Tang <tanggeliang(a)kylinos.cn>
v4:
- fix a bug in v3, it should be 'if (err)', not 'if (!err)'.
- move "selftests/bpf: Use log_err in network_helpers" out of this
series.
v3:
- add two more patches.
- use log_err instead of ASSERT in v3.
- let send_recv_data return int as Martin suggested.
v2:
Address Martin's comments for v1 (thanks.)
- drop patch 1, "export send_byte helper".
- drop "WRITE_ONCE(arg.stop, 0)".
- rebased.
send_recv_data will be re-used in MPTCP bpf tests, but not included
in this set because it depends on other patches that have not been
in the bpf-next yet. It will be sent as another set soon.
Geliang Tang (3):
selftests/bpf: Add struct send_recv_arg
selftests/bpf: Export send_recv_data helper
selftests/bpf: Support nonblock for send_recv_data

[PATCH net-next v2] selftest: epoll_busy_poll: epoll busy poll tests
by Joe Damato
Add a simple test for the epoll busy poll ioctls, using the kernel
selftest harness.
This test ensures that the ioctls have the expected return codes and
that the kernel properly gets and sets epoll busy poll parameters.
The test can be expanded in the future to do real busy polling (provided
another machine to act as the client is available).

[PATCH v2] selftests: exec: make binaries position independent
by Muhammad Usama Anjum
The -static overrides the -pie and binaries aren't position independent
anymore. Use -static-pie instead which would produce a static and
position independent binary. This has been caught by clang's warnings:
clang: warning: argument unused during compilation: '-pie'
[-Wunused-command-line-argument]
Tested with both gcc and clang after this change.
Fixes: 4d1cd3b2c5c1 ("tools/testing/selftests/exec: fix link error")

- Replace test_dev_cgroup with serial_test_dev_cgroup as there is
probability that the test is racing against another cgroup test
- Minor changes to the commit message above
I've tested the patch with vmtest.sh on bpf-next/for-next and linux
next. It is passing on both. Not sure why it was failed on BPFCI.

[PATCH v2] bpftool, selftests/hid/bpf: fix 29 clang warnings
by John Hubbard
When building either tools/bpf/bpftool, or tools/testing/selftests/hid,
(the same Makefile is used for these), clang generates many instances of
the following:
"clang: warning: -lLLVM-17: 'linker' input unused"
Quentin points out that the LLVM version is only required in $(LIBS),
not in $(CFLAGS), so the fix is to remove it from CFLAGS.

[PATCH] selftests/exec: build with -fPIE instead of -pie, to make clang happy
by John Hubbard
clang doesn't deal well with "-pie -static": it warns that -pie is an
unused option here. Changing to "-fPIE -static" solves this problem for
clang, while keeping the gcc results identical.
The problem is visible when building via:
make LLVM=1 -C tools/testing/selftests
Again: gcc 13 produces identical binaries for all of these programs,
both before and after this commit (using "-pie"), and after (using
"-fPIE").
Also, the runtime results are the same for both clang and gcc builds.

[PATCH 1/2] selftests/net: suppress clang's "variable-sized type not at the end" warning
by John Hubbard
When building with clang, via:
make LLVM=1 -C tools/testing/selftest
...clang warns that "a variable sized type not at the end of a struct or
class is a GNU extension".
These cases are not easily changed, because they involve structs that
are part of the API. Fortunately, however, the tests seem to be doing
just fine (specifically, neither affected test runs any differently with
gcc vs. clang builds, on my test system) regardless of the warning. So,
all the warning is doing is preventing a clean build of selftests/net.
Fix this by suppressing this particular clang warning for the
selftests/net suite.

[PATCH v2] selftests/netfilter: return a value for several "int" functions
by John Hubbard
When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...clang warns, correctly, that several functions declared with an "int"
return type are not always returning values in all cases (or at least,
clang cannot prove that they always return a value).
Fix this by returning an appropriate value for each function. Thanks to
Felix Huettner for recommending MNL_CB_OK (which is non-zero) for the
return value of the count_entries() callback.

Thanks for catching that, I'm sending a v2 with that fix.
I was thinking about it, and expected that the pre-existing code
appeared to work because the return value was some non-zero garbage
value scrounged off of the stack (or %rax, for example on x86).
However, just a quick test showed that *any* value (O, 1==MNL_CB_OK,
or no value at all) allows the test to report success...oh, I see,
it's reporting PASSED when it really ought to say SKIPPED:
$ ./conntrack_dump_flush

[PATCH v2] selftests/alsa: missing a return value in unused dump_config_tree()
by John Hubbard
dump_config_tree() is declared to return an int, but the compiler cannot
prove that it always returns any value at all. This leads to a clang
warning, when building via:
make LLVM=1 -C tools/testing/selftests
Furthermore, Mark Brown noticed that dump_config_tree() isn't even used
anymore, so just delete the entire function.

[PATCH] selftests/resctrl: fix clang build warnings related to abs(), labs() calls
by John Hubbard
First of all, in order to build with clang at all, one must first apply
Valentin Obst's build fix for LLVM [1]. Furthermore, for this particular
resctrl directory, my pending fix [2] must also be applied. Once those
fixes are in place, then when building with clang, via:
make LLVM=1 -C tools/testing/selftests
...two types of warnings occur:
warning: absolute value function 'abs' given an argument of type
'long' but has parameter of type 'int' which may cause truncation of
value
warning: taking the absolute value of unsigned type 'unsigned long'
has no effect
Fix these by:
a) using labs() in place of abs(), when long integers are involved, and
b) don't call labs() unnecessarily.

[PATCH v5 00/10] Fix Kselftest's vfork() side effects
by Mickaël Salaün
Hi,
This fifth series fixes _metadata reset and fixes the last patch to
handle code set with direct calls to _exit().
As reported by Kernel Test Robot [1], some pidfd tests fail. This is
due to the use of vfork() which introduced some side effects.
Similarly, while making it more generic, a previous commit made some
Landlock file system tests flaky, and subject to the host's file system
mount configuration.
This series fixes all these side effects by replacing vfork() with
clone3() and CLONE_VFORK, which is cleaner (no arbitrary shared memory)
and makes the Kselftest framework more robust.
I tried different approaches and I found this one to be the cleaner and
less invasive for current test cases.
I successfully ran the following tests (using TEST_F and
fork/clone/clone3, and KVM_ONE_VCPU_TEST) with this series:
- kvm:fix_hypercall_test
- kvm:sync_regs_test
- kvm:userspace_msr_exit_test
- kvm:vmx_pmu_caps_test
- landlock:fs_test
- landlock:net_test
- landlock:ptrace_test
- move_mount_set_group:move_mount_set_group_test
- net/af_unix:scm_pidfd
- perf_events:remove_on_exec
- pidfd:pidfd_getfd_test
- pidfd:pidfd_setns_test
- seccomp:seccomp_bpf
- user_events:abi_test
