Before, I confused asn_debug with asn1_xer_print. Have two distinct VTY
commands and fix documentation.
Put the asn_debug and asn1_xer_print implementations in iu.c.
Since they are globally defined, don't pass a pointer to iu_vty_init()
but just use it directly. Might be considered less clean, but is also less
bloat.

It makes sense semantically, and prepares for an upcoming commit that uses
the internal global config pointer in sgsn_vty_init(), which would not
be defined yet without this.

On 'auth-policy remote', the SGSN requires GSUP server address and port. If it
was missing, the SGSN would print a VTY warning and run anyway. Make this error
more fatal: print an error (flattened a bit) to stderr and abort the program.
Move validation of the GSUP server data presence out of the VTY command itself
and into the config reading function. This way the GSUP server config can be
given anywhere, including below the auth-policy config (was required above).
Don't care about setting the auth-policy to remote with a telnet VTY, because
in that case the GSUP client won't be started anyway.

Since ce9fec3e896571835ac5bfd2980d6836f2b29f0d libosmocore ignores
parameters to log_vty_command_* functions. Hence parameter of
logging_vty_add_cmds() is ignored too. As we depend on much later
libosmocore version anyway, we can simplify code somewhat by removing
parameters which will be ignored anyway.

Drop extern definitions of talloc_msgb_ctx and use msgb_talloc_ctx_init()
instead.
In sgsn_test.c, use a local variable msgb_ctx to do the talloc report
from the return value of msgb_talloc_ctx_init().

The A&C reference number specified in 3GPP TS 24.008 ยง 10.5.5.19
identifies particular request sent by network with the related response
sent by MS. The value transparently copied from request to response by
MS: the spec do not specify what exactly should be in there so we use
rand() to decrease chance for collisions.
Note: variable named 'rand' clashes with standard function rand() so it
was renamed.

Add ctrl_vty_init() calls and feed the ctrl_vty_get_bind_addr() return value to
ctrl_interface_setup() in the following programs:
osmo-bsc
osmo-bsc_nat
osmo-nitb
osmo-sgsn
For osmo-sgsn, move the control interface setup invocation below the config
parsing, so that the ctrl_vty_get_bind_addr() can return the configured
address.
|
|
Following the 'line vty'/'bind A.B.C.D' command added in libosmocore, use the
configured address to set the telnet bind for the VTY line. It is now possible
to publish the VTY on a specific local interface (including 0.0.0.0 aka "any").
Implement in all of:
osmo-gbproxy
osmo-gtphub
osmo-sgsn
osmo-bsc
osmo-bsc_nat
osmo-bsc_mgcp
osmo-nitb
In some of these main programs, move the telnet initialization below the
configuration parsing.
Historically, this was not a good idea for programs using bsc_init.c (aka
bsc_bootstrap_network()), since they expected a gsm_network struct pointer in
((struct telnet_connection*)vty->priv)->priv, so that telnet had to be either
initialized or replaced by a dummy struct. In the meantime, the gsm_network
struct is not actually looked up in a priv pointer but in the static bsc_vty.c
scope (bsc_gsmnet), so this limitation is mere legacy (even though said legacy
is still there in an "#if 0" chunk).
In the other binaries I have briefly looked at the init sequence dependencies
and found no reason to initialize telnet above the config file parsing. In any
case, I have tested every single one of abovementioned binaries to verify that
they still parse the example config successfully and launch, allowing VTY
connections on the configured address(es). I hope this suffices.
In all of the above, log VTY address and port. LOGL_INFO is disabled by default
in some of the logging scopes, and since it is a single log message right at
program launch, I decided for the slightly more aggressive LOGL_NOTICE.

It mentioned AGPLv3+ and refers to the hyperlink of v3, but still
stated "Version 2 or later". That was a typo at the time.

clang complained that different enums are mixed with the
return type and we actually want this to be an int now.

For real networks we need to check if the requested APN string
is allowed and then resolve the GGSN address through DNS. There
are countries with two or three digit MNCs and one could either
try to keep a list of countries that have two/three digits or
just try both of them. I have opted for the later for the ease
of the implementation.
C-Ares doesn't allow to cancel a request so we will need to
have the MMCTX and the Lookup have different lifetimes. We simply
set ->mmctx to NULL in case the MMCTX dies more early.
The selected and verified apn_str will be copied into the out
parameter. In case no static APN/GGSN config is present and the
dynamic mode is enabled a request will be made.

This is consuming the new signals and allows to install several
different CDR/observing/event/audit modules in the future. For
getting the bytes in/out the code would have had to undo what the
rate counter is doing and at the same time adding a "total" to
the ratecounter didn't look like a good idea, the same went for
making it a plain counter.
Begin writing the values one by one and open/closing a new FILE
for every log messages. This is not efficient but easily deals
with external truncation/rotation of the file (no fstat for and
checking the links and size). As usual we will wait and see if
this is an issue.
Add some new members to our PDP context structure to see what it
is about.

Currently old LLMEs and MM contexts that haven't been explicitly
detached or cancelled are not removed until another request with the
same IMSI is made. These stale entries may accumulate over time and
severely compromise the operation of the SGSN.
This patch implements age based LLME expiry, when the maximum age has
been reached, the corresponding MM context is cancelled. If such an MM
context doesn't exist, the LLME is unassigned directly.
The implementation works as follows.
- llme->age_timestamp is reset on each received PTP LLC message
- sgsn_llme_check_cb is invoked periodically (each 30s)
- sgsn_llme_check_cb sets the age_timestamp to the current time if
it has been reset
- sgsn_llme_check_cb computes the age and expires the LLME if
it exceeds gprs_max_time_to_idle()

This patch adds GPRS specific functions for gsm_subscriber objects
(allocation, retrieval, deletion) and subscriber data
requests/updates. The sgsn_update_subscriber_data callback is used to
notify the sgsn about updates and is extended by a parameter that
passes a reference to a gsm_subscriber.

Currently the function in sgsn_auth.c either have an sgsn_config or
an sgsn_instance parameter. Since then global sgsn variable is
already being used in that file and since other parts of the SGSN
related code also rely on a global sgsn singleton, these parameters
pretend to provide a flexibility that is not really supported.
Therefore this patch removes these parameters except for the ACL
related functions, which do not call code that uses the sgsn
variable.

Currently the VTY 'auth-policy' command results in setting or clearing
the acl_enabled flag. This also enables the matching of the MCC/MNC
prefix of the IMSI.
This patch adds an additional policy 'acl-only' which disables the
MCC/MNC matching and relies on the ACL only.

Currently the ACL code is located in sgsn_vty.c.
This commit moves this to a new file sgsn_auth.c as a first step to
make authorization more flexible in order to implement remote
acquisition on subsciber data.

This adds a minimalistic ACL by which certain, individual roaming IMSIs
can be authorized to use the SGSN. So you can selectively bypass the
'MCC+MNC == first 5 digits of IMSI' checking for a couple of IMSIs

We change the minority of functions employing the gprs_bssgp_ prefix to
match with the majority without gprs_ in front.

Instead of direct function calls to individual functions, we now
generate primitives (osmo_prim) and send them to one
application-provided function "bssgp_prim_cb()"

Rather than using openbsc internal data/functions, we now use only

This is a big patch that ports openBSC over libosmo-abis.
Sorry, the changes that are included here are all dependent
of libosmo-abis, splitting them into smaller pieces would
leave the repository in some intermediate state, which is
not desired.
The main changes are:
- The directory libabis/ has been removed as it now lives in
libosmo-abis.
- new configuration file format for nanoBTS and HSL femto, we
need to define the virtual e1_line and attach it to the OML
link.
- all the existing BTS drivers (nanoBTS, hsl femto, Nokia site,
BS11 and rbs2000) now use the new libosmo-abis framework.
- use r232 input driver available in libosmo-abis for bs11_config.
- use ipa_msg_recv instead of old ipaccess_read_msg function.
- delete definition of gsm_e1_subslot and input_signal_data.
These structures now lives in libosmo-abis.
Most of this patch are deletions of libabis/ which has been
moved to libosmo-abis.
This patch also modifies openBSC to use all the new definitions
available in libosmocore and libosmo-abis. In order to do that,
we have replaced the following:
- DINP, DMI, DMIB and DMUX by their respective DL* correspondences.
- SS_GLOBAL by SS_L_GLOBAL
- SS_INPUT by SS_L_INPUT
- S_GLOBAL_SHUTDOWN by S_L_GLOBAL_SHUTDOWN
- SS_INPUT by SS_L_INPUT
- S_INP_* by S_L_INP_* sub-signals
- E1INP_NODE by L_E1INP_NODE vty node
This patch has been tested with:
- one nanoBTS
- the HSL femto with the examples available under libosmo-abis
- BS11 with both dahdi and misdn drivers.
