v2 was an accidental re-post of the same patches, this time for real: Changes to first version: * Use struct value_string[] instead of switch{} for auth_action_str(). * Tweak first and last patch's log message.

MM Auth: return AUTH_NOT_AVAIL instead of hardcoded zero Fix MM Auth: disallow key_seq mismatch Fix MM Auth: zero-initialize auth tuple before first use openbsc/.gitignore | 1 + openbsc/configure.ac | 1 + openbsc/include/openbsc/auth.h | 9 + openbsc/src/libmsc/auth.c | 33 +++- openbsc/tests/Makefile.am | 2 +- openbsc/tests/mm_auth/Makefile.am | 21 +++ openbsc/tests/mm_auth/mm_auth_test.c | 340 ++++++++++++++++++++++++++++++++++ openbsc/tests/mm_auth/mm_auth_test.ok | 40 ++++ openbsc/tests/testsuite.at | 7 + 9 files changed, 446 insertions(+), 8 deletions(-) create mode 100644 openbsc/tests/mm_auth/Makefile.am create mode 100644 openbsc/tests/mm_auth/mm_auth_test.c create mode 100644 openbsc/tests/mm_auth/mm_auth_test.ok -- 2.1.4

[PATCH 0/7] Introduce MM Auth test suite and fix two issues
by Neels Hofmeyr 29 Mar '16

29 Mar '16

Though MM Auth might be tested implicitly, it is acutely lacking a dedicated test suite. I found two problems in the MM Auth logic, and to have regression tests for those, I need an actual test suite. So, at first I add a bread-and-butter test suite for MM Auth. Then, I cosmetically improve use of constants in return values. Finally, I fix the two issues with reflection in the new tests. Neels Hofmeyr (7): Add MM Auth test; add auth_action_str() function MM Auth test: add two tests for AUTH_THEN_CIPH MM Auth test: add test to re-use existing auth MM Auth: introduce AUTH_ERROR constant.

[PATCH] osmo-bsc: fix compiler warning: store struct in vty->index

Don't store an MSC index number in the vty->index void* value. Instead, store the osmo_msc_data struct directly.
