In some systems, the netcat server can incur in delay to start listening. When this happens, the test can randomly fail in various points. This is an example error message:
# ip gre none gso # encap 192.168.1.1 to 192.168.1.2, type gre, mac none len 2000 # test basic connectivity # Ncat: Connection refused.
The issue stems from a race condition between the netcat client and server. The test author had addressed this problem by implementing a sleep, which I have removed in this patch. This patch introduces a function capable of sleeping for up to two seconds. However, it can terminate the waiting period early if the port is reported to be listening.

Recently, I frequently hit the following test failure:
[root@arch-fb-vm1 bpf]# ./test_progs -n 33/1 test_lookup_update:PASS:skel_open 0 nsec [...] test_lookup_update:PASS:sync_rcu 0 nsec test_lookup_update:FAIL:map1_leak inner_map1 leaked! #33/1 btf_map_in_map/lookup_update:FAIL #33 btf_map_in_map:FAIL
In the test, after map is closed and then after two rcu grace periods, it is assumed that map_id is not available to user space.
But the above assumption cannot be guaranteed. After zero or one or two rcu grace periods in different siturations, the actual freeing-map-work is put into a workqueue. Later on, when the work is dequeued, the map will be actually freed. See bpf_map_put() in kernel/bpf/syscall.c.
By using workqueue, there is no ganrantee that map will be actually freed after a couple of rcu grace periods. This patch removed such map leak detection and then the test can pass consistently.

Using a struct_group seems to reliably avoid the warning and not make the code much uglier. The combined memset() should even save a couple of cpu cycles.

trace_drop_common() also disables interrupts, but this is a minor issue because we could easily replace it with a local_lock.
Replace the spin_lock with raw_spin_lock to avoid sleeping in atomic context.

[ Upstream commit 28027ec8e32ecbadcd67623edb290dad61e735b5 ]
The qedi_dbg_do_not_recover_cmd_read() function invokes sprintf() directly on a __user pointer, which results into the crash.
To fix this issue, use a small local stack buffer for sprintf() and then call simple_read_from_buffer(), which in turns make the copy_to_user() call.

This happens because netpoll_owner_active() needs to check if the current CPU is the owner of the lock, touching napi->poll_owner non atomically. The ->poll_owner field contains the current CPU holding the lock.
Use an atomic read to check if the poll owner is the current CPU.

Lenovo Slim 7 16ARH7 is a machine with switchable graphics between AMD and Nvidia, and the backlight can't be adjusted properly unless acpi_backlight=native is passed. Although nvidia-wmi-backlight is present and loaded, this doesn't work as expected at all.
For making it working as default, add the corresponding quirk entry with a DMI matching "LENOVO" "82UX".

Please drop this patch in all backports (and FWIW, any fix in drivers/hid/bpf/progs/).
HID-BPF is only available since kernel v6.3, and the compilation output of the in-tree file is not used directly, but shipped from udev-hid-bpf.
TL;DR: this just adds noise to those stable kernel trees.
