Hi all,
This patch series continues the work to migrate the script tests into
prog_tests.
test_xdp_meta.sh uses the BPF programs defined in progs/test_xdp_meta.c
to do a simple XDP/TC functional test that checks the metadata
allocation performed by the bpf_xdp_adjust_meta() helper.
This is already partly covered by two tests under prog_tests/:
- xdp_context_test_run.c uses bpf_prog_test_run_opts() to verify the
validity of the xdp_md context after a call to bpf_xdp_adjust_meta()
- xdp_metadata.c ensures that these meta-data can be exchanged through
an AF_XDP socket.
However test_xdp_meta.sh also verifies that the meta-data initialized
in the struct xdp_md is forwarded to the struct __sk_buff used by BPF
programs at 'TC level'. To cover this, I add a test case in
xdp_context_test_run.c that uses the same BPF programs from
progs/test_xdp_meta.c.

When compiling the pointer masking tests with -Wall this warning
is present:
pointer_masking.c: In function ‘test_tagged_addr_abi_sysctl’:
pointer_masking.c:203:9: warning: ignoring return value of ‘pwrite’
declared with attribute ‘warn_unused_result’ [-Wunused-result]
203 | pwrite(fd, &value, 1, 0); |
^~~~~~~~~~~~~~~~~~~~~~~~ pointer_masking.c:208:9: warning:
ignoring return value of ‘pwrite’ declared with attribute
‘warn_unused_result’ [-Wunused-result]
208 | pwrite(fd, &value, 1, 0);
I came across this on riscv64-linux-gnu-gcc (Ubuntu
11.4.0-1ubuntu1~22.04).
Fix this by checking that the number of bytes written equal the expected
number of bytes written.

Add ip_link_set_addr(), ip_link_set_up(), ip_addr_add() and ip_route_add()
to the suite of helpers that automatically schedule a corresponding
cleanup.
When setting a new MAC, one needs to remember the old address first. Move
mac_get() from forwarding/ to that end.

2.47.0
This series is a follow-up to v1[1], aimed at making the watchdog selftest
more suitable for CI environments. Currently, in non-interactive setups,
the watchdog kselftest can only run with oneshot parameters, preventing the
testing of the WDIOC_KEEPALIVE ioctl since the ping loop is only
interrupted by SIGINT.
The first patch adds a new -c option to limit the number of watchdog pings,
allowing the test to be optionally finite. The second patch updates the
test output to conform to KTAP.
The default behavior remains unchanged: without the -c option, the
keep_alive() loop continues indefinitely until interrupted by SIGINT.
[1] https://lore.kernel.org/all/20240506111359.224579-1-laura.nao@collabora.com/
Changes in v2:
- The keep_alive() loop remains infinite by default
- Introduced keep_alive_res variable to track the WDIOC_KEEPALIVE ioctl return code for user reporting

Currently, user needs to manually enable transmit hardware timestamp
feature of certain Ethernet drivers, e.g. stmmac and igc drivers, through
following command after running the xdp_hw_metadata app.
sudo hwstamp_ctl -i eth0 -t 1
To simplify the step test of xdp_hw_metadata, set tx_type to HWTSTAMP_TX_ON
to enable hardware timestamping for all outgoing packets, so that user no
longer need to execute hwstamp_ctl command.
