Move the regexp parsing code from the NAT to libcommon as it will
be used by the NAT and BSC code. This also adds the #include <regex.h>
include to gsm_data. This header should be split up.
|
|
The commands net.<netid>.bsc.<bscid>.* are now forwarded to the
appropriate osmo-bsc. <netid> for now is just 0. <bscid> is not the LAC
anymore (since that could be ambiguous), but instead the number as
configured in bsc-nat.cfg

The new function now mimcis the behaviour of
assign_src_local_reference from bsc_sccp.c

nat: Catch up with controlif_setup API change
We now save a control handle reference in the nat
osmo-bsc: Catch up with controlif_setup API change
We now save a control handle reference in the gsm network
|
|
The osmo_daemonize moved from process.h to application.h (that
is already included), remove the process.h include.

and propagate -ENOMEM in case we have no memory
|
|
We want to avoid spaghetti code by creating smaller functions,
which also helps with the line lengths / indentation levels.
|
|
this avoids us to copy+paste external declarations over all 'main'
files.
|
|
Passes commands beginning with "bsc.<num>" to the bsc that is
responsible for LAC <num>.

Match the used SMSC and the destination of the SMS and change
the SMSC address if both are matched.
|
|
Use the same filtering infrasturcture to patch the SMSC
address in a CP-DATA/RP-DATA message. Add a very simple
testcase for this code.
|
|
|
|
Refactor the code to allow having different handlers. The goal
is to be able to patch some SMS messages too.
|
|
The idea that MCC and MNC is enough to classify a subscriber
turns out to be wrong. Certain operatos license a number range
of IMSIs to others. When we see a '^' in the MCC field we treat
it as a regexp. The code now turns the MCC/MNC into a regexp
for the IMSI. It is not using extended POSIX regexp to match
the behavior of the access list.
|
|
Remove the arteficial limitation of the number format
of an unknown number.
|
|
Separate the code to patch the code and the code to find a
new number based on the old number. This will allow to add
multiple targets for number changing.
|
|
Make paging-group deprecated and introduce the new paging group.
|
|
Use the libosmocore code to ignore certain signals by
default (e.g. SIGHUP, SIGPIPE) and use the new code to
create a default stderr logging target and initialize
it properly.

Introduce a paging group that a BSC can refer to and is used
during the LAC lookup. This way paging can be flooded through
the network and just filtered at the last element in the core.
|
|
A paging group is a list of LACs, different BSCs can point
to a paging group and use it for the LAC lookup.
|
|
The current code tries to find _one_ bsc for a paging message
and then continues. The new code will try to find multiple BSCs
for each LAC. This is done in preparation of having two BSCs
handle the same LAC. This code right now is O(m*n) but it will
be worse once paging groups are landed.
The code to test the function was reduced to just test the lac
lookup code as the other part can not be tested in a standalone
setup anymore.
|
|
Be able to configure a list of destinations (duplicates allowed)
that will be tried in a round robin fashion. The change is in
the bsc_msc_connection to operate on a list. We achieve the
round robin nature with the same trick used in the paging code
to delete and append the current entry. The nat code was updated
to compile but one can only configure one destination.
|
|
For restarting the NAT we can now block it, it will not accept
new connections and for existing connections it will attempt
to drop them over time. A blocked NAT will end up with no BSC
connections left and then can be safely restarted.
|
|
In case this is a local USSD connection we will ignore
the clear command and respond with a RLC to any RLSD but
will never forward that to the BSC. This way the external
USSD is fully in charge of the connection.
There are theoretical issues if there are multiple transactions
on the same SCCP Connection but this can not be solved properly
right now.
|
|
Keep track of the used transaction identifier and always forward
messages to the USSD provider. E.g. this can be used to have a
dialogue going. Right now it is still possible that the MSC will
close down the connection.
|
|
|
|
Remove the usage of 0, 1, 2 and start using enum values. We can
still assume con_local is a number.
|
|
|
|
We need to and out the protocol discriminator as call control
might have use transactions. This has only failed for the USSD
filter so far as this must deal with transactions.
|
|
Now ipaccess_idtag_parse() returns -EINVAL instead of -1. We also
check for the return value of this function in every invocation to
skip further processing in case of messages with malformed TLVs.
This idea was suggested by Zecke.
