====================
bpf: Allow XDP_REDIRECT for XDP dev-bound programs

In the current implementation if the program is dev-bound to a specific
device, it will not be possible to perform XDP_REDIRECT into a DEVMAP or
CPUMAP even if the program is running in the driver NAPI context.
Fix the issue introducing __bpf_prog_map_compatible utility routine in
order to avoid bpf_prog_is_dev_bound() during the XDP program load.
Continue forbidding to attach a dev-bound program to XDP maps.

Merge branch 'for-6.15/amd_sfh' into for-linus

From: Mario Limonciello <mario.limonciello@amd.com>

Some platforms include a human presence detection (HPD) sensor. When
enabled and a user is detected a wake event will be emitted from the
sensor fusion hub that software can react to.

Example use cases are "wake from suspend on approach" or to "lock
when leaving".

This is currently enabled by default on supported systems, but users
can't control it. This essentially means that wake on approach is
enabled which is a really surprising behavior to users that don't
expect it.

Instead of defaulting to enabled add a sysfs knob that users can
use to enable the feature if desirable and set it to disabled by
default.

btf_decl_tag is still WIP, but this is a great milestone.

in-range index will always succeed (Daniel Xu)

Merge branch 'selftests-bpf-migrate-test_flow_dissector-sh-to-test_progs'

Alexis Lothoré says:

====================
This is the revision 3 of test_flow_dissector_migration.sh into
test_progs. This revision addresses comments from Stanislas, especially
about proper reuse of pseudo-header checksuming in new network helpers.

There are 2 "main" parts in test_flow_dissector.sh:
- a set of tests checking flow_dissector programs attachment to either
root namespace or non-root namespace
- dissection test

The first set is integrated in flow_dissector.c, which already contains
some existing tests for flow_dissector programs. This series uses the
opportunity to update a bit this file (use new assert, re-split tests,
etc)
The second part is migrated into a new file under test_progs,
flow_dissector_classification.c. It uses the same eBPF programs as
flow_dissector.c, but the difference is rather about how those program
are executed:
- flow_dissector.c manually runs programs with BPF_PROG_RUN
- flow_dissector_classification.c sends real packets to be dissected, and
so it also executes kernel code related to eBPF flow dissector (eg:
__skb_flow_bpf_to_target)

---
Changes in v3:
- Keep new helpers name in sync with kernel ones
- Document some existing network helpers
- Properly reuse pseudo-header csum helper in transport layer csum
helper
- Drop duplicate assert
- Use const for test structure in the migrated test
- Simplify shutdown callchain for basic test
- collect Acked-by
- Link to v2: https://lore.kernel.org/r/20241114-flow_dissector-v2-0-ee4a3be3de65@bootlin.com

Changes in v2:
- allow tests to run in parallel
- move some generic helpers to network_helpers.h
- define proper function for ASSERT_MEMEQ
- fetch acked-by tags
- Link to v1: https://lore.kernel.org/r/20241113-flow_dissector-v1-0-27c4df0592dc@bootlin.com

This error is due to struct udphdr being defined in both <linux/udp.h>

Use only <netinet/udp.h> in every test. While at it, perform the same
for tcp.h. For some tests, the change needs to be done in the eBPF
program part as well, because of some headers sharing between both
sides.
