72bc8da537 mgcp_client: drop a bunch of dead code
Remove public API that makes no sense anymore and is dead code.

I see the dropped API as a dead-end initial misconception of the early mgcp
client, and it doesn't really make sense to drag this stuff along. It has not
been used by osmo-msc,-bsc for a long time now, and just confuses the reader.

It is public API, yes, and older versions of osmo-msc / osmo-bsc will not be
able to compile against this, but even if it did, the resulting MGCP client
would not work with the current osmo-mgw: this API is still based on the
premise that the MGCP client dictates the MGW endpoint numbers, a concept that
cannot be used with the current osmo-mgw. Instead, osmo-mgw expects a
wildcarded endpoint upon CRCX and assigns its own endpoint names.

Also, the bts-base configuration is unused and a legacy of when osmo-bsc_mgcp
had explicit BTS and CN sides.

c3132fd508 mgcp_client_vty: fix missing talloc_free
If the vty client enters multiple local / remote addresses, that leaks talloc
memory of the previously set addresses. Free those first, if any, using
osmo_talloc_replace_string().

ad21a0e166 check_rtp: on IP:port errors, log the IP and port
Half of those are obviously zero, but I'd rather print the raw data instead of
adding string constants, even if the condition must always lead to 0.0.0.0:0.

Rationale: I had osmo-mgw listen on 0.0.0.0 and got the error message
  DRTP ERROR endpoint:0x1 destination IP-address is invalid
which didn't convey that 0.0.0.0 is regarded as invalid.

32d15cc8ba drop/replace very weird logging in mgcp_client.c
mgcp_do_write() is the final stage of writing data towards the MGCP server
(MGW). In that function, drop an unconditional iteration and copy of the MGCP
message to a static string buffer for no apparent reason besides debug logging.

Instead, use osmo_escape_str() with a limited length, which can just be an
inline format argument in the LOGP() statement. This way, the string mangling
is simpler and only gets run when DMGCP is actually on debug log level.

6802374574 contrib/jenkins.sh: build and publish manuals
Add new environment variables WITH_MANUALS and PUBLISH to control if
the manuals should be built and uploaded. Describe all environment vars
on top of the file.

When WITH_MANUALS is set, install osmo-gsm-manuals like any other
dependency and add --enable-manuals to the configure flags (for "make"
and "make distcheck"). Add the bin subdir of the installed files to
PATH, so osmo-gsm-manuals-check-depends can be used by ./configure.

5a5169e15c jenkins.sh: remove leftover MGCP env variable
Jenkins currently runs the build twice, once with
MGCP="--enable-mgcp-transcoding" and once with
MGCP="--disable-mgcp-transcoding". The configure.ac does not have this
parameter, so let's remove the confusing variable.

This is in preparation for describing all environment variables used in
jenkins.sh (follow up commit).

Moved to doc/manuals/, with full commit history, in preceding merge commit.
Now incorporate in the build system.

- the repository is checked out in ../osmo-gsm-manuals; or
- if it osmo-gsm-manuals was installed with "make install"; or
- OSMO_GSM_MANUALS_DIR is set.

the structural improvements:

- using section names that match the VTY prompt.

While here, rename MGCP_MDCX_FAIL_DEFERRED_BY_POLICY to
MGCP_MDCX_DEFERRED_BY_POLICY; we have decided that deferred connections
aren't failures, and this keeps names used by DLCX and MDCX in sync.

Also remove some allocation failure checks with OSMO_ASSERT(); such
checks aren't en vogue anymore.

Even though osmo-mgw advertises the -s option, the getopt configuration lacks

8dbc9ed408 mgcp_protocol: increase buffer space for codec name in LCO
The function that parses the LCO uses an internal buffer to store the
codec name that has been issued via LCO. This buffer is only 9 byte
long, this means an 8 character string can be stored. If a codec name
exceeds this limit it gets chopped. For example "GSM-HR-08" becomes
"GSM-HR-0", which may mess up the codec negotiation.

- Increase the buffer from 9 to 17 byte.

     crcx:alloc_conn_fail:          0 (0/s 0/m 0/h 0/d) connection allocation failure.
 crcx:no_remote_conn_desc:          1 (0/s 1/m 0/h 0/d) no opposite end specified for connection.
   crcx:start_rtp_failure:          0 (0/s 0/m 0/h 0/d) failure to start RTP processing.
       crcx:conn_rejected:          0 (0/s 0/m 0/h 0/d) connection rejected by policy.

bcd52e5724 mgcp: Fix osmux_cid_bitmap static array size calculation
Right now it's not a big issue since OSMUX_CID_MAX is 255, so 255+1 is
256 which fits array boundaries correctly (multiple of 8). However, if
for example OSMUX_CID_MAX was modified to be 12, 12+1/8 = 1, so we'd
have an undesired memory access when accessing last 4 CIDs.

A +1 should be kept on top, because OSMUX_CID_MAX specified the maximum
number used by a CID, that is (0,OSMUX_CID_MAX), and as a result we
require OSMUX_CID_MAX+1 slots.

4ca0b0d1fa debian: Remove dangling symlink to osmo-bsc-mgcp.service
osmo-bsc-mgcp was removed recently from osmo-mgw.git as it belongs to
openbsc.git.
This symlink was a leftover from that time.

efd645e5a8 log: avoid logging early media as error
When the peer address is still 0.0.0.0, the endpoint is not yet configured.
This commonly happens before bridging a call is complete, so instead of ERROR
logging about an invalid packet, rather INFO-log this as "early media".

e28b673fba cosmetic: mgcp_test: fix get_conn_id_from_response()
This function is implemented in such a weird way that I couldn't stop myself
from rewriting it.

a77eade744 mgcp_conn_get(): match conn Id ('I:') despite leading zeros
The Connection Identifier is defined as a hex string, so clients may send the
ID back with or without leading zeros. Ignore all leading zeros when comparing.

A specific SCCPlite MSC is observed to DLCX with Connection Identifier with
leading zeros removed, which would mismatch pefore this patch.

Extend test_conn_id_matching() in mgcp_test.c to include leading zero tests.

Now, mgcp_conn_get() would match a valid id with *any* amount of leading zeros,
even if that far surpasses the permitted conn id length. Valid lengths of
incoming conn ids should be and is checked elsewhere.

6531726a02 mgcp_conn_get(): compare conn Id ('I:') case insensitively
The Connection Identifier is defined as a hex string, so clients may send the
ID back in lower case. Convert to upper case before comparing.

A specific SCCPlite MSC is observed to DLCX with Connection Identifier in lower
case, which would mismatch pefore this patch.

Add test_conn_id_matching() in mgcp_test.c to verify case insensitivity.

Cosmetic: use strcmp(), not strncmp(). In the presence of a terminating nul as
we can assume here, this makes no functional difference, but it clarifies the
code.
