net/gnrc/sock: Implement sock_aux_local #14704

maribu · 2020-08-05T07:35:09Z

Contribution description

This PR adds the implementation of the sock_aux_local for GNRC, that provides access to the local address via the extended SOCK API of #14703.

Testing procedure

make -C tests/gnrc_sock_udp flash test
make -C tests/gnrc_sock_ip flash test

Issues/PRs references

Depends on #14703

Same as #14705, but for GNRC

sys/net/gnrc/sock/ip/gnrc_sock_ip.c

maribu · 2020-11-04T09:41:03Z

I changed the implementation a bit (I think it is now more elegant) and used #if IS_USED() over #ifdef in all places.

maribu · 2020-12-03T11:20:24Z

I rebased on master and solved merged conflict (all regarding the documentation fixes in the API, not relevant to this PR).

I did however not squash

maribu · 2020-12-03T11:29:22Z

I messed up the rebase. This time it should have worked.

sys/net/gnrc/sock/gnrc_sock.c

tests/gnrc_sock_ip/Makefile

tests/gnrc_sock_udp/Makefile

maribu · 2020-12-04T08:40:09Z

OK, only the expected failures: The ds3231 test requires hardware to be plugged in to work (and was blacklisted on the CI in #15554). And the issue with libhydrogen on clang is also preexisting.

sys/net/gnrc/sock/gnrc_sock.c

miri64

One last thing:

sys/net/gnrc/sock/ip/gnrc_sock_ip.c

sys/net/gnrc/sock/udp/gnrc_sock_udp.c

miri64 · 2020-12-04T11:02:34Z

Please squash. I will give the tests a final local run.

miri64 · 2020-12-04T11:17:24Z

I ran the tests with the following script on native:

TEST_RUNS=0
for test in tests/gnrc_sock_{ip,udp}; do
    RIOT_CI_BUILD=1 AUX_LOCAL=1 make -C ${test} --no-print-directory -j clean flash test || break
    RIOT_CI_BUILD=1 AUX_LOCAL=0 make -C ${test} --no-print-directory -j clean flash test || break
    TEST_RUNS=$((TEST_RUNS+1))
done
[ ${TEST_RUNS} -eq 2 ] && echo "success" || echo "fail"

Success was printed in the end and the build sizes differed:

Non-native should be covered by the tests on Murdock and we already discussed, that their failures where unrelated.

miri64

Static tests failed because of a missing doc.

miri64 · 2020-12-04T11:41:21Z

sys/net/gnrc/sock/include/gnrc_sock_internal.h

+#if !IS_USED(MODULE_SOCK_AUX_LOCAL)
+    uint8_t this_struct_is_not_empty;
+#endif


Murdock wants this to be documented. Maybe just hide it from it?

Suggested change

#if !IS_USED(MODULE_SOCK_AUX_LOCAL)

uint8_t this_struct_is_not_empty;

#endif

#if !IS_USED(MODULE_SOCK_AUX_LOCAL) && !IS_ACTIVE(DOXYGEN)

uint8_t this_struct_is_not_empty;

#endif

I'm not sure if Doxygen is so smart that it can parse IS_ACTIVE() - it would need a C99 compliant preprocessor for this.

Maybe it is indeed the easiest to just document it.

I'm not sure if Doxygen is so smart that it can parse IS_ACTIVE() - it would need a C99 compliant preprocessor for this.

I think in that case it is just enough to check if it is not defined

Suggested change

#if !IS_USED(MODULE_SOCK_AUX_LOCAL)

uint8_t this_struct_is_not_empty;

#endif

#if !IS_USED(MODULE_SOCK_AUX_LOCAL) && !defined(DOXYGEN)

uint8_t this_struct_is_not_empty;

#endif

Provide address the IP packet / UDP datagram was received on in the auxiliary data, if module sock_aux_local is used.

I extended the doc of the struct and squashed right in. See here for the diff.

miri64 · 2020-12-04T11:53:02Z

I think the revert commit can also squashed into the commit it reverts ;-).

maribu · 2020-12-04T11:55:17Z

I think the revert commit can also squashed into the commit it reverts ;-).

Good catch. Maybe I should stop blindly trusting --autosquash.

It's awesome, but I never understood why Revert commits are not included in that :-/

miri64

ACK. Code is sane and I provided tests as well as ran the tests on Murdock.
