Andreas Eversberg 6e182087f4 Fix: LAPDm contention resoltion must acknowledge subsequent SABM
After reception of SABM, the network responds with UA and enters the
establised multiframe state. If UA is not received by mobile, the SABM
is transmitted again, and the network must respond with UA again, unless
it is from a different mobile.

Add LAPDm collision test (contention resolution on network side).

Sylvain Munaut ed8170ac67 codec: Fix the GSM 06.20 ordering tables
Seems the script I used to parse those had a bug where range of
bits in the 'decreasing' direction ( like 6..0 ) were not processed
properly.

Thanks to Andreas for noticing this !

Holger Hans Peter Freyther a6428d2376 Follow up fix for the log level "everything"
Commit cd6ed82d1f made "EVERYTHING"
map to LOGL_DEBUG but when writing out the configuration the following
would be written:

  logging level all unknown 0x0

This happend because no string was found for the value 0. Address it
by adding a legacy check for 0 and write out the str from the index
0. Currently this is "EVERYTHING".

Harald Welte cd6ed82d1f Fix log level "everything" and make it equal to "debug"
As Holger points out "logging level XXX everything" wasn't working, as
it sets category->loglevel to 0, which is checked in osmo_vlogp() and
will never get logged.

Katerina Barone-Adesi c28c6a02d2 misc: Doxygen tweaks: fixed some typos and minor errors
Doxygen generates quite a lot of warnings on libosmocore. Some of them

Harald Welte d17aa59c3e VTY: don't show HIDDEN or DEPRECATED vty commands in ? completion
This hides HIDDEN or DEPRECATED commands from showing up when the
full list of commands is inquired with '?' at any given point in the
command tree.  Only if the hidden/deprecated command is already typed
in partially, then it will still tab-complete.

Harald Welte 868a5c4782 turn abis_nm_debugp_foh() into a macro
this will avoid printing 'abis_nm.c' as the filename in the log, which
is pretty useless during debugging.  We want to know where
abis_nm_debugp_foh() is being used from, not where it is implemented.

While at it, this patch also removes hints.ai_flags = 0 as memset
to zero already happened just a bit before that.

Sylvain Munaut 01e0604637 core/bits: Prevent osmo_revbytebits_buf stack trashing
The second loop in osmo_revbytebits_buf() in src/bits.c grabs
4 bytes each iteration, which can easily go past the supplied
input in some cases.

Compiled with -fstack-protector , I get a "stack smashing detected"
in the bits test.

Daniel Willmann e523392c2c lapd: Check in rslms_rx_rll() if lapdm context was initialized earlier
This was found while implementing handover on a sysmobts. When we
receive a channel release request for a channel that was never really
activated (set_lapdm_context() was not called) we segfault in
lapd_recv_dlsap().

We now return early with -EINVAL in rslms_rx_rll() if we receive a
message that assumes set_lapdm_context() was already called.

These are:
* RSL_MT_UNIT_DATA_REQ
* RSL_MT_DATA_REQ
* RSL_MT_SUSP_REQ
* RSL_MT_REL_REQ

A test case was added to trigger the issue.

GCC 4.7.2 was already smart enough to see that the table is const
so there is no change in the generated assembly code. For some reason
the dispatch is still going through one relocation.

Holger Hans Peter Freyther bcf125c524 smr: Introduce an id and prefix all log messages with SMR(ID)
When OpenBSC is handling more than one message at a time it is difficult
to see which log message belongs to which SMR instance. Introduce a
uint64_t id that can be set to the row_id/message_id and prefix all
log messages with SMR(ID).

This change is ABI and API incompatible with previous versions of
libosmogsm.

Tobias Engel 2db368ee8d Define struct iphdr for OSX
Use FreeBSD struct iphdr definition for OSX also. From the commentary in
the source file:
On BSD the IPv4 struct is called struct ip and instead of iXX
the members are called ip_XX. One could change this code to use
struct ip but that would require to define _BSD_SOURCE and that
might have other complications. Instead make sure struct iphdr
is present on FreeBSD.
