Merge branch 'selftests-bpf-fix-for-bpf_signal-stalls-watchdog-for-test_progs'

Eduard Zingerman says:

====================
selftests/bpf: fix for bpf_signal stalls, watchdog for test_progs

Test case 'bpf_signal' had been recently reported to stall, both on
the mailing list [1] and CI [2]. The stall is caused by CPU cycles
perf event not being delivered within expected time frame, before test
process enters system call and waits indefinitely.

This patch-set addresses the issue in several ways:
- A watchdog timer is added to test_progs.c runner:
- it prints current sub-test name to stderr if sub-test takes longer
than 10 seconds to finish;
- it terminates process executing sub-test if sub-test takes longer
than 120 seconds to finish.
- The test case is updated to await perf event notification with a
timeout and a few retries, this serves two purposes:
- busy loops longer to increase the time frame for CPU cycles event
generation/delivery;
- makes a timeout, not stall, a worst case scenario.
- The test case is updated to lower frequency of perf events, as high
frequency of such events caused events generation throttling,
which in turn delayed events delivery by amount of time sufficient
to cause test case failure.

Note:

librt pthread-based timer API is used to implement watchdog timer.
I chose this API over SIGALRM because signal handler execution
within test process context was sufficient to trigger perf event
delivery for send_signal/send_signal_nmi_thread_remote test case,
w/o any additional changes. Thus I concluded that SIGALRM based
implementation interferes with tests execution.

selftests/bpf: allow send_signal test to timeout

The following invocation:

$ t1=send_signal/send_signal_perf_thread_remote \
t2=send_signal/send_signal_nmi_thread_remote \
./test_progs -t $t1,$t2

Leads to send_signal_nmi_thread_remote to be stuck
on a line 180:

/* wait for result */
err = read(pipe_c2p[0], buf, 1);

In this test case:
- perf event PERF_COUNT_HW_CPU_CYCLES is created for parent process;
- BPF program is attached to perf event, and sends a signal to child
process when event occurs;
- parent program burns some CPU in busy loop and calls read() to get
notification from child that it received a signal.

The perf event is declared with .sample_period = 1.
This forces perf to throttle events, and under some unclear conditions
the event does not always occur while parent is in busy loop.
After parent enters read() system call CPU cycles event won't be
generated for parent anymore. Thus, if perf event had not occurred
already the test is stuck.

This commit updates the parent to wait for notification with a timeout,
doing several iterations of busy loop + read_with_timeout().

Merge tag 'net-next-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Not much excitement - a handful of large patchsets (devmem among them)
did not make it in time.

Core & protocols:

- Use local_lock in addition to local_bh_disable() to protect per-CPU
resources in networking, a step closer for local_bh_disable() not
to act as a big lock on PREEMPT_RT

- Use flex array for netdevice priv area, ensure its cache alignment

- Add a sysctl knob to allow user to specify a default rto_min at
socket init time. Bit of a big hammer but multiple companies were
independently carrying such patch downstream so clearly it's useful

- Support scheduling transmission of packets based on CLOCK_TAI

- Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned
off using cpusets

- Support multiple L2TPv3 UDP tunnels using the same 5-tuple address

- Allow configuration of multipath hash seed, to both allow
synchronizing hashing of two routers, and preventing partial
accidental sync

- Improve TCP compliance with RFC 9293 for simultaneous connect()

- Support sending NAT keepalives in IPsec ESP in UDP states.
Userspace IKE daemon had to do this before, but the kernel can
better keep track of it

- Support sending supervision HSR frames with MAC addresses stored in
ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled

- Introduce IPPROTO_SMC for selecting SMC when socket is created

- Allow UDP GSO transmit from devices with no checksum offload

- openvswitch: add packet sampling via psample, separating the
sampled traffic from "upcall" packets sent to user space for
forwarding

- nf_tables: shrink memory consumption for transaction objects

Things we sprinkled into general kernel code:

- Power Sequencing subsystem (used by Qualcomm Bluetooth driver for
QCA6390) [ Already merged separately - Linus ]

- Add IRQ information in sysfs for auxiliary bus

- Introduce guard definition for local_lock

- Add aligned flavor of __cacheline_group_{begin, end}() markings for
grouping fields in structures

BPF:

- Notify user space (via epoll) when a struct_ops object is getting
detached/unregistered

- Add new kfuncs for a generic, open-coded bits iterator

- Enable BPF programs to declare arrays of kptr, bpf_rb_root, and
bpf_list_head

- Support resilient split BTF which cuts down on duplication and
makes BTF as compact as possible WRT BTF from modules

- Add support for dumping kfunc prototypes from BTF which enables
both detecting as well as dumping compilable prototypes for kfuncs

- riscv64 BPF JIT improvements in particular to add 12-argument
support for BPF trampolines and to utilize bpf_prog_pack for the
latter

- Add the capability to offload the netfilter flowtable in XDP layer
through kfuncs

Driver API:

- Allow users to configure IRQ tresholds between which automatic IRQ
moderation can choose

- Expand Power Sourcing (PoE) status with power, class and failure
reason. Support setting power limits

- Track additional RSS contexts in the core, make sure configuration
changes don't break them

- Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated
ESP data paths

- Support updating firmware on SFP modules

Tests and tooling:

- mptcp: use net/lib.sh to manage netns

- TCP-AO and TCP-MD5: replace debug prints used by tests with
tracepoints

- openvswitch: make test self-contained (don't depend on OvS CLI
tools)
