Eric Wild acb80088b3 allow specifying gsmtap dest ip 
This allows distinguishing multiple modems by specifying another
loopback ip i.e. -i 127.0.0.4
Linux has a default local route for 127.0.0.0/8 so it "just works".

Harald Welte 0442fead33 Enable + Interpret more GPRS related logging 
Those logging groups are not present on all firmwares/devices.  Best
success for GPRS low-layer logging so far with an old Gobi2000 card from
Lenovo.

Harald Welte 4e5338bc49 WIP: SIM Card logging 
I'm getting related messages from the modem, but I somehow cannot decode
the traces so far at all :/

Harald Welte 78b8bda6f6 fix gen_log_config_set_mask() 
We were missing the last byte in the log config mask, resulting in
unintended behavior.

Harald Welte 7e6d71ea74 also log config request/response messages via GSMTAP 2017-01-08 16:04:47 +01:00
Harald Welte b8a70980b6 patch %s out of format strings received from phone 
%s can obviously not work, as we have no access to the targets memory
space on the host PC.  I guess the programmers adding those log lines
have done so in error.  Let's replace %s with %p in the format string.

Harald Welte 5fa552cbd3 separate diag_log_umts to diag_log_wcdma 
Qualcomm differentiates between WCDMA (the access stratum) and UMTS (the
non access stratum).  Let's reflect that here.  As an added bonus, we
get working NAS protocol traces.

Harald Welte a32c769bb7 Generate GSMTAP messages from raw received DIAG frames 
This forwards the raw DIAG messages via GSMTAP, so the receiver (e.g.
wireshark) will have to do a full DIAG protocol decode.  I currently
prefer this idea to that of converting only the protocol payload to
"native" GSMTAP messages like GSMTAP_UM.

One of the problems is that the LAPDm headers are alrady stripped, and
we would have to re-add fake LAPDm headers to generate GSMTAP_UM.  So
let's rather forward all information we have and let wireshark deal with
it.

I'm not entirely sure if this is  the best strategy, but we can always
implement both modes and switch between them at runtime.

Harald Welte a115fbb1bb diag_read_msg(): Discard any messages shorter than 3 bytes 
The 16bit CRC and the FLAG octet together are 3 bytes.  If a message is
shorter than that, something is going wrong, for sure.

Harald Welte 89c159c873 add printing of DIAG_QSR_EXT_MSG_TERSE_F 
Those are QSHRINK type messages where the format-string is not contained
in the message itself but would have to be provided from an external
source and looked up by a hash.
