The fix in 0fb294a8dd 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.
Change-Id: I63393decfe42a24dab56c7654f716c1580416ab2
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

Fixes: Coverity CID 169684
Commit b78a4a6dfe 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
da7250ad2c, 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.

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.

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

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:

Change-Id: I24fc32eb55baaf22f9c6fdda917bfb8395d02b1c
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.

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.

In libosmocore, my patch was merged to master a bit too soon. To accomodate the

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

This adds compression of bitmap in PUAN. The compressed bitmap
is used only if the number of bits in the bitmap does not fit in
the message and there is a gain after compression.
The algorithm is part of libosmocore and so there is dependency
on the libosmocore for compilation.
The algorithm is tested on integration setup by forcing compression.
