These commands are introduced to enable the server to request the
full reset of all state in a client or bankd. This is particularly
useful in TTCN-3 tests, where we typically want to reset the state
between tests.

Otherwise the loop for SIGMAPDEL delivery code will match any
unused worker for bank_id=0/slot_nr=0, which is not what we want.
This also makes repeated RemsimBankd_Tests.TC_removeMapping_connected
runs work reliably.

It's a bit of a matter of taste whether we should simply log + ignore
if the Client of a removeMappingReq doesn't match what the bankd
currently has configured. I chose to reject it, as a new createMapping
for the same bandk+slot will overwrite any existing mapping anyway,
at least as of I83e319d22896b881c0d882542842f500075aa546

As explained in OS#4278, a remsim-bankd currently doesn't recover after
a remsim-server resetart, since old mappings remain in the bankd, and
the server has no chance of removing them.
To avoid this problem, a createMapping now always implicitly removes
any existing mapping that may exist for the given bankdSlot.

It is customary in the IPA protocol that a a server side
responds with an ID_ACK if the client sends an ID_ACK. Due
to the lack of any protocol specification, it's unclear why
exactly, but we know it does happen.
osmo-remsim-bankd so far failed to implement this, which is
not directly a problem as the only user (osmo-remsim-client)
didn't care. However, when executing TTCN3 test cases,
the IPA_Emulation expects that ID_ACK and related test fail.

ipa_client_conn_destroy() really only destroys the object, but not close
the underlying file descriptor. This leads to old connections
lingering around, which in turn (in case of the remsim client) will
occupy banksim worker threads.

for the osmo-remsim-client-st2 client,
the command line arguments bankd-port and slot-nr have been renamed
to server-port and client-slot in the opts options, but not in the
help output.
this is now fixed.

Initially it seemed like a good idea that rspro_dec_msg() takes care
of freeing the input msgb when generating a new decoded output
structure. However, in reality this made the implementation of
every caller more complicated, as it had to treat messages going into
rspro_dec_msg() differently than messages going elsewhere.
Adding to that, not every caller got it right, and the comments were
disagreeing about what happens to msgb ownership in erroneous cases.
Change-Id: I55d5d61922053fd94e2b5a8cdf0d799b29feec98
We basically must ensure that all code paths *except* the path leading
to rspro_dec_msg() must call msgb_free(msg). This was not the case
in two situations, as fixed now.
Change-Id: I29f8413bb43b3ebf827be0bceda1a4db1e6e2b7c
respro_dec_msg() takes ownership of the input msgb in both
successful and unsuccessful cases, so we must not call talloc_free
on the resulting msgb.
Change-Id: Id54d1b73395da1329a998d213c190da49eb90a93
We need to unconditionally free the msgb that gets handed into
sock_read_cb() by the ipa server.

As we're waiting in blocking mode (and hence block things like the
IPA keepalive FSM), we cannot afford to block for 100s in one shot.

Once we know the Client / Bankd Identity, update not only the connection
FSM with that identity, but also the IPA keepalive FSM. This will
provide proper context when logging.

This fixes a crash where the modem/phone would sent APDUs at a time
when there is no connection to the bankd yet. If we transmit the
RSPRO PDUs via the FSM, this cannot happen.

The point is that the ClientId is only set once at start-up (and
also only optionally), while the Bank IP/port/ID/slot can be changed
any number of times during a RSPRO connection.

The bankd worker threads handle the RSPRO connection from the
remsim-clients outside of our usual osmo* infrastructure and hence
they don't inherit the common IPA CCM handling. This means we need
to explicitly implement the keep-alive PONG support.
What this doesn't add is any outbound keepalive handling towards
the client.

If the main thread receives SIGUSR1, we dump its talloc report and
then signal all worker threads so each can dump their own talloc
report.
Change-Id: I89e7e22de5557376bd5a9625662d99ac0badf00c
This implements a signal based mechanism by which the main thread can
inform worker threads that their mapping has just been removed and
they should hence terminate the connection and return themselves to the
pool.

"remsim-client" is the client program running next to a phone/modem
which is attaching to the SIM slot.
"RSPRO client" is a protocl-level client of the RSPRO protocol:
* the remsim-client connects as RSPRO client to the remsim-server
* the remsim-client connects as RSPRO client to the remsim-bankd
* the remsim-bankd connects as RSPRO client to the remsim-server
Let's clarify this in naming.

This allows the RSPRO client FSM to be used by both remsim-client
as well as remsim-bankd -- both of which connect as RSPRO client to
remsim-server.
Change-Id: I57b5f8dc9de522b6ae8ceb030e639b5b8001b55a
If the client uses a locally-configured (static) ClientId, then
the bankd_client_fsm.c code needs access to this information
at time of the connect to the server, not just when connecting
to the bankd.
