selftests/bpf: Store BPF object files with .bpf.o extension
BPF object files are, in a way, the final artifact produced as part of the ahead-of-time compilation process. That makes them somewhat special compared to "regular" object files, which are a intermediate build artifacts that can typically be removed safely. As such, it can make sense to name them differently to make it easier to spot this difference at a glance.
Among others, libbpf-bootstrap [0] has established the extension .bpf.o for BPF object files. It seems reasonable to follow this example and establish the same denomination for selftest build artifacts. To that end, this change adjusts the corresponding part of the build system and the test programs loading BPF object files to work with .bpf.o files.

We have switched to memcg-based memory accouting and thus the rlimit is not needed any more. LIBBPF_STRICT_AUTO_RLIMIT_MEMLOCK was introduced in libbpf for backward compatibility, so we can use it instead now. After this change, the header tools/testing/selftests/bpf/bpf_rlimit.h can be removed.
This patch also removes the useless header sys/resource.h from many files in tools/testing/selftests/bpf/.

bpf, selftests: Use single cgroup helpers for both test_sockmap/progs
Nearly every user of cgroup helpers does the same sequence of API calls. So push these into a single helper cgroup_setup_and_join. The cases that do a bit of extra logic are test_progs which currently uses an env variable to decide if it needs to setup the cgroup environment or can use an existingi environment. And then tests that are doing cgroup tests themselves. We skip these cases for now.

selftests: bpf: enable hi32 randomization for all tests
The previous libbpf patch allows user to specify "prog_flags" to bpf program load APIs. To enable high 32-bit randomization for a test, we need to set BPF_F_TEST_RND_HI32 in "prog_flags".
To enable such randomization for all tests, we need to make sure all places are passing BPF_F_TEST_RND_HI32. Changing them one by one is not convenient, also, it would be better if a test could be switched to "normal" running mode without code change.
Given the program load APIs used across bpf selftests are mostly: bpf_prog_load: load from file bpf_load_program: load from raw insns
A test_stub.c is implemented for bpf seltests, it offers two functions for testing purpose:
bpf_prog_test_load bpf_test_load_program
The are the same as "bpf_prog_load" and "bpf_load_program", except they also set BPF_F_TEST_RND_HI32. Given *_xattr functions are the APIs to customize any "prog_flags", it makes little sense to put these two functions into libbpf.
Then, the following CFLAGS are passed to compilations for host programs: -Dbpf_prog_load=bpf_prog_test_load -Dbpf_load_program=bpf_test_load_program
They migrate the used load APIs to the test version, hence enable high 32-bit randomization for these tests without changing source code.
Besides all these, there are several testcases are using "bpf_prog_load_attr" directly, their call sites are updated to pass BPF_F_TEST_RND_HI32.

selftests/bpf: fix incorrect users of create_and_get_cgroup
We have some tests that assume create_and_get_cgroup returns -1 on error which is incorrect (it returns 0 on error). Since fd might be zero in general case, change create_and_get_cgroup to return -1 on error and fix the users that assume 0 on error.
Fixes: f269099a7e7a ("tools/bpf: add a selftest for bpf_get_current_cgroup_id() helper") Fixes: 7d2c6cfc5411 ("bpf: use --cgroup in test_suite if supplied")
v2: - instead of fixing the uses that assume -1 on error, convert the users that assume 0 on error (fd might be zero in general case)

selftests/bpf: Test [::] -> [::1] rewrite in sys_sendmsg in test_sock_addr
Test that sys_sendmsg BPF hook doesn't break sys_sendmsg behaviour to rewrite destination IPv6 = [::] with [::1] (BSD'ism).
selftests/bpf: Test [::] -> [::1] rewrite in sys_sendmsg in test_sock_addr
Test that sys_sendmsg BPF hook doesn't break sys_sendmsg behaviour to rewrite destination IPv6 = [::] with [::1] (BSD'ism).
Two test cases are added:
1) User passes dst IPv6 = [::] and BPF_CGROUP_UDP6_SENDMSG program doesn't touch it.
2) User passes dst IPv6 != [::], but BPF_CGROUP_UDP6_SENDMSG program rewrites it with [::].
In both cases [::1] is used by sys_sendmsg code eventually and datagram is sent successfully for unconnected UDP socket.
Example of relevant output: Test case: sendmsg6: set dst IP = [::] (BSD'ism) .. [PASS] Test case: sendmsg6: preserve dst IP = [::] (BSD'ism) .. [PASS]

selftests/bpf: Test sys_connect BPF hooks with TFO
TCP Fast Open is triggered by sys_sendmsg with MSG_FASTOPEN flag for SOCK_STREAM socket.
Even though it's sys_sendmsg, it eventually calls __inet_stream_connect the same way sys_connect does for TCP. __inet_stream_connect, in turn, already has BPF hooks for sys_connect.
That means TFO is already covered by BPF_CGROUP_INET{4,6}_CONNECT and the only missing piece is selftest. The patch adds selftest for TFO.

selftests/bpf: Prepare test_sock_addr for extension
test_sock_addr was not easy to extend since it was focused on sys_bind and sys_connect quite a bit.
Reorganized it so that it'll be easier to cover new test-cases for `BPF_PROG_TYPE_CGROUP_SOCK_ADDR`:
- decouple test-cases so that only one BPF prog is tested at a time;
- check programmatically that local IP:port for sys_bind, source IP and destination IP:port for sys_connect are rewritten property by tested BPF programs.

In test_sock, bpf program loads failed due to hitting memlock limits. In test_sock_addr.sh, my test machine is a ipv6 only test box and using "ping" without specifying address family for an ipv6 address does not work.
This patch fixed the issue by including header bpf_rlimit.h in test_sock.c and test_sock_addr.c, and specifying address family for ping command.

selftests/bpf: Selftest for sys_bind hooks
Add selftest to work with bpf_sock_addr context from `BPF_PROG_TYPE_CGROUP_SOCK_ADDR` programs.
Try to bind(2) on IP:port and apply: * loads to make sure context can be read correctly, including narrow loads (byte, half) for IP and full-size loads (word) for all fields; * stores to those fields allowed by verifier.
All combination from IPv4/IPv6 and TCP/UDP are tested.
Both scenarios are tested: * valid programs can be loaded and attached; * invalid programs can be neither loaded nor attached.
Test passes when expected data can be read from context in the BPF-program, and after the call to bind(2) socket is bound to IP:port pair that was written by BPF-program to the context.
Example: # ./test_sock_addr Attached bind4 program. Test case #1 (IPv4/TCP): Requested: bind(192.168.1.254, 4040) .. Actual: bind(127.0.0.1, 4444) Test case #2 (IPv4/UDP): Requested: bind(192.168.1.254, 4040) .. Actual: bind(127.0.0.1, 4444) Attached bind6 program. Test case #3 (IPv6/TCP): Requested: bind(face:b00c:1234:5678::abcd, 6060) .. Actual: bind(::1, 6666) Test case #4 (IPv6/UDP): Requested: bind(face:b00c:1234:5678::abcd, 6060) ..

So push these into a single helper cgroup_setup_and_join. The cases that do a bit of extra logic are test_progs which currently uses an env variable to decide if it needs to setup the cgroup environment or can use an existingi environment.
