Two subtests in ksyms_module.c are not qualified as static, so these subtests are exported as standalone tests in tests.h and lead to confusion for the output of "./test_progs -t ksyms_module".

2022-02-07ipv4: Reject routes specifying ECN bits in rtm_tosGuillaume Nault1-0/+76
Use the new dscp_t type to replace the fc_tos field of fib_config, to ensure IPv4 routes aren't influenced by ECN bits when configured with non-zero rtm_tos. Before this patch, IPv4 routes specifying an rtm_tos with some of the ECN bits set were accepted. However they wouldn't work (never match) as IPv4 normally clears the ECN bits with IPTOS_RT_MASK before doing a FIB lookup (although a few buggy code paths don't). After this patch, IPv4 routes specifying an rtm_tos with any ECN bit set is rejected. Note: IPv6 routes ignore rtm_tos altogether, any rtm_tos is accepted, but treated as if it were 0.

2022-02-07ipv4: Stop taking ECN bits into account in fib4-rulesGuillaume Nault1-1/+29
Use the new dscp_t type to replace the tos field of struct fib4_rule, so that fib4-rules consistently ignore ECN bits. Before this patch, fib4-rules did accept rules with the high order ECN bit set (but not the low order one). Also, it relied on its callers masking the ECN bits of ->flowi4_tos to prevent those from influencing the result. This was brittle and a few call paths still do the lookup without masking the ECN bits first. After this patch fib4-rules only compare the DSCP bits. ECN can't influence the result anymore, even if the caller didn't mask these bits. Also, fib4-rules now must have both ECN bits cleared or they will be rejected.

2022-02-07ipv6: Define dscp_t and stop taking ECN bits into account in fib6-rulesGuillaume Nault1-1/+29
Define a dscp_t type and its appropriate helpers that ensure ECN bits are not taken into account when handling DSCP. Use this new type to replace the tclass field of struct fib6_rule, so that fib6-rules don't get influenced by ECN bits anymore. Before this patch, fib6-rules didn't make any distinction between the DSCP and ECN bits. Therefore, rules specifying a DSCP (tos or dsfield options in iproute2) stopped working as soon a packets had at least one of its ECN bits set (as a work around one could create four rules for each DSCP value to match, one for each possible ECN value). After this patch fib6-rules only compare the DSCP bits. ECN doesn't influence the result anymore. Also, fib6-rules now must have the ECN bits cleared or they will be rejected.

2022-02-07selftests/bpf: Fix tests to use arch-dependent syscall entry pointsNaveen N. Rao11-23/+34
Some of the tests are using x86_64 ABI-specific syscall entry points (such as __x64_sys_nanosleep and __x64_sys_getpgid). Update them to use architecture-dependent syscall entry names. Also update fexit_sleep test to not use BPF_PROG() so that it is clear that the syscall parameters aren't being accessed in the bpf prog. Note that none of the bpf progs in these tests are actually accessing any of the syscall parameters. The only exception is perfbuf_bench, which passes on the bpf prog context into bpf_perf_event_output() as a pointer to pt_regs, but that looks to be mostly ignored. Signed-off-by: Naveen N.

2022-02-07selftests/bpf: Use "__se_" prefix on architectures without syscall wrapperNaveen N. Rao1-1/+1
On architectures that don't use a syscall wrapper, sys_* function names are set as an alias of __se_sys_* functions. Due to this, there is no BTF associated with sys_* function names. This results in some of the test progs failing to load. Set the SYS_PREFIX to "__se_" to fix this issue.

'ip mptcp' used the ID number argument to find out the address to change flags, while 'pm_nl_ctl' used the address and port number arguments.

This patch added the backup testcase using an address with a port number. The original backup tests only work for the output of 'pm_nl_ctl dump' without the port number. It chooses the last item in the dump to parse the address in it, and in this case, the address is showed at the end of the item. But it doesn't work for the dump with the port number, in this case, the port number is showed at the end of the item, not the address.

2022-02-03selftests: rtnetlink: Use more sensible tos valuesGuillaume Nault1-2/+2
Using tos 0x1 with 'ip route get <IPv4 address> ...' doesn't test much of the tos option handling: 0x1 just sets an ECN bit, which is cleared by inet_rtm_getroute() before doing the fib lookup. Let's use 0x10 instead, which is actually taken into account in the route lookup (and is less surprising for the reader). For consistency, use 0x10 for the IPv6 route lookup too (IPv6 currently doesn't clear ECN bits, but might do so in the future).

2022-02-03selftests: fib offload: use sensible tos valuesGuillaume Nault1-6/+6
Although both iproute2 and the kernel accept 1 and 2 as tos values for new routes, those are invalid. These values only set ECN bits, which are ignored during IPv4 fib lookups. Therefore, no packet can actually match such routes. This selftest therefore only succeeds because it doesn't verify that the new routes do actually work in practice (it just checks if the routes are offloaded or not). It makes more sense to use tos values that don't conflict with ECN. This way, the selftest won't be affected if we later decide to warn or even reject invalid tos configurations for new routes.

The main changes are: 1) Fix BPF ringbuf to allocate its area with VM_MAP instead of VM_ALLOC flag which otherwise trips over KASAN, from Hou Tao. 2) Fix unresolved symbol warning in resolve_btfids due to LSM callback rename, from Alexei Starovoitov. 3) Fix a possible race in inc_misses_counter() when IRQ would trigger during counter update, from He Fengqing. 4) Fix tooling infra for cross-building with clang upon probing whether gcc provides the standard libraries, from Jean-Philippe Brucker. 5) Fix silent mode build for resolve_btfids, from Nathan Chancellor. 6) Drop unneeded and outdated lirc.h header copy from tooling infra as BPF does not require it anymore, from Sean Young. * https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf: tools/resolve_btfids: Do not print any commands when building silently bpf: Use VM_MAP instead of VM_ALLOC for ringbuf tools: Ignore errors from `which' when searching a GCC toolchain tools headers UAPI: remove stale lirc.h bpf: Fix possible race in inc_misses_counter bpf: Fix renaming task_getsecid_subj->current_getsecid_subj. ==================== Link: https://lore.kernel.org/r/20220203155815.25689-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>

All callers of fib_rule6_test_match_n_redirect() and fib_rule4_test_match_n_redirect() pass a third argument containing a description of the test being run.

The fib_rule6_del_by_pref() and fib_rule4_del_by_pref() functions use an uninitialised $TABLE variable. They should use $RTABLE instead. This doesn't alter the result of the test, as it just makes the grep command less specific (but since the script always uses the same table number, that doesn't really matter). Let's fix it anyway and, while there, specify the filtering parameters directly in 'ip -X rule show' to avoid the extra grep command entirely.

2022-01-31kselftest: Fix vdso_test_abi return statusVincenzo Frascino1-73/+62
vdso_test_abi contains a batch of tests that verify the validity of the vDSO ABI. When a vDSO symbol is not found the relevant test is skipped reporting KSFT_SKIP. All the tests return values are then added in a single variable which is checked to verify failures. This approach can have side effects which result in reporting the wrong kselftest exit status. Fix vdso_test_abi verifying the return code of each test separately.

2022-01-31selftests/net: timestamping: Fix bind_phc checkGerhard Engleder1-2/+2
timestamping checks socket options during initialisation. For the field bind_phc of the socket option SO_TIMESTAMPING it expects the value -1 if PHC is not bound. Actually the value of bind_phc is 0 if PHC is not bound. This results in the following output: SIOCSHWTSTAMP: tx_type 0 requested, got 0; rx_filter 0 requested, got 0 SO_TIMESTAMP 0 SO_TIMESTAMPNS 0 SO_TIMESTAMPING flags 0, bind phc 0 not expected, flags 0, bind phc -1 This is fixed by setting default value and expected value of bind_phc to 0.
