2017-06-11lc15: further fixes regarding --with-litecell15Harald Welte2-5/+5
The fix in 0fb294a8dd45a86b8f9eb93211b69b6dbf0a6853 was only partially valid, as it unconditionally used $includedir, without any prefix. This polluted the include path with host include files in cross-compiling builds. Let's take a different approach and simply define LITECELL15_CFLAGS (similar to what pkgconfig does), which makes the "-I" go away if no --with-litecell15 has been specified.

2017-06-11lc15: fix configure.ac variable substitution causing compile errorHarald Welte1-1/+1
When "--enable-lc15bts-phy" is passed to './configure' without specifying an explicit header file path using "--with-litecell15=", we ended up generating an empty string as LITECELL15_INCDIR and rendered something like "-DENABLE_DIRECT_PHY -I -I../../git/src/osmo-bts-litecell15" as part of the compiler invocation, where the -I with no argument will hide the second -I, as the second one is supposed to be the optarg for the first include. This in turn made the "#include <lc15_l1_if.h>" fail, when using separate source and build directories. This patch fixes the configur script to use $includedir, rather than the non-existant $incdir as default for LITECELL15_INCDIR Change-Id: I483e62f8331e7867a92f8055c4d450fdd5288cb6

2017-05-15fix PACCH paging: don't return early in case of NULL TBFNeels Hofmeyr1-7/+8
Commit b78a4a6dfef217c538d45949a6ae725e22a36b05 tried to fix a NULL dereference error, but apparently was overly eager to return, because it looked like all code paths would dereference the tbf. In fact the code path further above, for msg != NULL, has "always" dereferenced the tbf, but the lower code path, the one effecting the paging, has only started to dereference tbf since shortly before the overly eager fix: in da7250ad2c1cd5ddc7d3c6e10435a00b357ef8f7, to "update the dl ctrl msg counter for ms". It seems that this tbf dereference in the paging path is bogus and the cause for the segfault that made me write the early exit fix. Fix that fix: Do not exit early if tbf == NULL, stay in there to be able to reach the paging path below. In case of a message to be sent, assume that tbf is present, and verify: print an error message and abort if there is a msg but no tbf, so that we will see the error if I'm wrong there. If a tbf is missing, free the msg. In case of no message, go on to send pending pagings, but do not attempt to count ctrl messages for a tbf -- IIUC there will never be a tbf if we're paging. This should avoid segfaults while keeping PACCH paging intact. Tweak a comment for and add a blank line above the paging section.

2017-03-27bitcomp test: use expected rc instead of 'verify' flagNeels Hofmeyr2-41/+51
The 'verify' flag is useless, we always want to verify everything. Replace 'verify' with 'expect_rc', expecting a specific decoding result per test set. When an error code was returned, cut short the loop and skip printing expected vs. decoded bits. This uncovers the fact that the first test marked as "invalid inputs" does not seem to be invalid after all, or at least does not produce an error to be returned. For now, only uncover this fact, the fix shall be submitted later. Change-Id: Icf815a8f1acb0e275463408450171df046879847
2017-03-27bitcomp test: fix: also verify bits after decoded dataNeels Hofmeyr2-16/+5
Before this, the expected data had seemingly random bits set after the end of the expected decoding result. Make the test expect these extra bits as zero, matching with the buffer initialization to zero. In result_matches(), compare the full length of bytes instead of masking the bits after the end of the decoded data (which caused us to not catch the wrong expectation until now). This fixes the underlying issues found in http://lists.osmocom.org/pipermail/osmocom-net-gprs/2017-March/000876.html [osmo-pcu 0.2.896-0a8f] testsuite: 4 failed from: Arnaud ZANETTI on: Fri Mar 24 09:53:53 UTC 2017 Change-Id: I2501208e2f8b4f709efbcadbd1057c086472c9e6
2017-03-27bitcomp test: fix: only one hexdump per log; use printfNeels Hofmeyr2-19/+17
The test wants to write multiline results, so it should use printf instead of the logging system. Split logs to only one hexdump per printf(). One cannot use osmo_hexdump twice in one printf(); before this, one of the two hexdumps won, both dumps would show as the same. Very bad for a regression test! This uncovers a discrepancy between expected and produced results, proving that the expected stderr output was not capable of uncovering test failures. The test's check_result() function *has* always verified the decoded data, but only up to the last decoded bit. Our expected data contains seemingly random bits after the end of the decoded bits, but check_result() never compares those, hence we don't catch that error. The extra bits should definitely be zero, because the destination buffer is pre-initialized to zero -- fixed in a subsequent patch. This should cosmetically fix the build failure found in: http://lists.osmocom.org/pipermail/osmocom-net-gprs/2017-March/000876.html [osmo-pcu 0.2.896-0a8f] testsuite: 4 failed from: Arnaud ZANETTI on: Fri Mar 24 09:53:53 UTC 2017 The real fix will follow.

2017-03-27cosmetic: BitcompTest: make readableNeels Hofmeyr1-37/+45
In order to understand what the bitcomp test is logging, cosmetically rearrange the code: - memset bits_data before assigning to destination bitvec. - use macro CEIL_DIV_8 to clarify what (x+7)/8 does. - rename check_result() to result_matches() and return a bool, also constify result_matches() args and pass a bitvec reference instead of copying the bitvec struct. - rearrange logging lines to make readable what is going on there. - drop unused 'init_flag' There are obviously errors like double hexdumps per log line, multiple newlines in a LOGP statement and so forth: these shall be fixed by subsequent patches.

2017-03-05BTS: Convert relative frame numbers to absolute frame numbersPhilipp Maier6-16/+301
The implementation of the method rcv_rach() in class BTS, restores the absolute frame number of the incoming RACH-Request by using the relative frame number (RFn = Fn mod 42432) from the rach request and the already known internal absolute frame number m_cur_fn, which is continusly updated by the CCU interface. In some rare cases, a RACH request might be received by the BTS, a very short time before the frame number wraps in its 42432. Depending on the PCU location, RACH request might be received by the BSC, which forwards it to the PCU. It is then likely that, while the RACH request is being forwarded to the PCU, the PCU internal absolute frame number wraps before the RACH can be processed. The relative frame number from the rach request would then be interpreted as if it were received after the wrapping of the internal frame number modulos. This commit adds logic to detect and resolve this race condition. Also a unit test is added to check some cornercases. Change-Id: I74f00c11e5739d49f370ce6c357149e81d9aa759

2017-01-26BTS: accept also relative frame numbers with rach requstPhilipp2-1/+19
The rach request contains a relative frame number (Fn % 42432), while BTS::rcv_rach() accepts the full frame number only. Since the BTS is always aware of the full frame number this is not a problem. But for BSC co-located PCU schemes it is a problem since the rach request only contains the relative frame number as mentioned above. The pcu continusly receives frame number updates with the GSM time indication message. It is simple to re-calculate the full frame number from that information. This patch makes BTS::rcv_rach() compatible with relative frame numbers, while not breaking the compatibility for full frame numbers Change-Id: Iaa182d8d29c6a0f5fa06064c2eb48b21b1ba2775
