2011-05-12misc: Use the osmo_init code for signals and loggingHolger Hans Peter Freyther2-20/+14
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.

2011-04-18misc: Remove sys/types.h includes from the filesHolger Hans Peter Freyther7-7/+0
These are not needed any more. We used them for u_int types but we now use uint which comes from stdint.h
2011-04-18misc: Move from u_int to uint types of stdint.hHolger Hans Peter Freyther3-4/+4
This was done with sed on the files.
2011-03-28src: include new file osmocom/vty/misc.h for vty_out_rate_ctr_group()Pablo Neira Ayuso1-0/+1
This uses the new include file for vty_out_rate_ctr_group() which available in libosmocore.
2011-03-23Fix build of bsc-nat and GPRS code after include path changeHarald Welte4-5/+5
The last patch changed the osmocore include paths, this fixes some build problems caused by it
2011-03-23src: use new library libosmogsm and new path to headers in libosmocorePablo Neira Ayuso13-48/+48
libosmogsm is a new library that is distributed in the libosmocore. Now, openbsc depends on it. This patch gets openbsc with this change. This patch also rewrites all include path to the new osmocom/[gsm|core] Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
2011-03-23src: fix use of logging_vty_add_cmds() without log_info parameterPablo Neira Ayuso2-2/+4
This patch fixes: CC gb_proxy_main.o gb_proxy_main.c: In function ‘main’: gb_proxy_main.c:224: warning: implicit declaration of function ‘logging_vty_add_cmds’ And a similar problem in osmo-bsc_nat. This was introduced in by myself in patch: "bsc: change bsc_vty_init to take logging categories as parameter" Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
2011-03-04prefix sub-directories containing libraries with 'lib'Harald Welte1-2/+5
... and make sure tests work again after restructuring
2011-03-03Move 'Gb' protocol stack into its own src/gb subdirectoryHarald Welte7-3025/+4
2011-03-03re-structure the OpenBSC directory layoutHarald Welte1-6/+4
The new structure divides the code into a number of libraries for the BSC core functionality, MSC core functionality, Abis transport, TRAU and other bits. This doesn't introduce any functional code change but simply moves around files and alters Makefile.am accordingly. Next step would be to disentangle a lot of the inter-library dependencies and make the individual bits of code more independent.
2011-02-24Use shorter vty_app_info->name for all appsHarald Welte2-2/+2
... as this is now used as SYSLOG ident
2011-02-19Install programs into $(prefix)/bin, not /sbinHarald Welte1-2/+2
At least in many configurations, there is no need to run any of our programs as root. Thus, we shouldn't install them in sbin.
2011-02-18LOGGING: make sure to make the 'logging filter' compatible with vty log cfgHarald Welte2-12/+10
Recent libosmocore introdues a way how log targets can be configured from the VTY. This commit makes the 'log filter (imsi|nsvc|bvc)' compatible with it.
2011-02-06[gb_proxy] vty: display the BVC BLOCKED status in 'show gbproxy'Harald Welte1-4/+6
2011-02-06[gb_proxy] make sure bssgp cell id is copied correctlyHarald Welte1-1/+3
When we copy a msgb, we need to make sure the msgb_cb->bssgp_cell_id pointer points to data in the new message, not in the old message. Thanks to Dieter Spaar for spotting this.
2011-02-06[gb proxy] treat BVCI=1 consistently like signallingHarald Welte1-2/+2
1 is reserved for point-to-multipoint data, i.e. not a point-to-point BVCI.
2011-02-06[gb_proxy] Convert a NS-BLOCK from BSS into BVC-RESET to SGSNHarald Welte1-12/+31
As we only have one NS-VC between gb_proxy and SGSN, we cannot forward a NS-BLOCK from the BSS to the SGSN, as it would affect all other BSS's, too. Thus, we check if we have an unblocked PTP-BVC in the NSVC to the BSS, and then issue a BVC-BLOCK towards the SGSN. This should prevent any further PDU's from the SGSN to be sent to this BSS.
2011-02-06[gb_proxy] Track the state of blocked/unblocked BVC in the proxyHarald Welte1-13/+59
This allows us to reject any additional messages sent by the SGSN after the BVC was blocked (+ acknowledged to be blocked)
2011-01-14update gitignoreHarald Welte1-0/+2
2011-01-01[SGSN] Fix processing of RA Update Request regarding TLLIHarald Welte2-1/+27
In case we get a RA UPD REQ on a new cell (both served by the same SGSN), the LLC stack should not allocate a ne LLE/LLME, as the latter would reset the V(u)sent / V(u)recv to zero and make the MS discard our responses. Instead, whenever the LLC stack sees a foreign TLLI, it should always convert it to the local TLLI before doing any lookup for a LLE/LLME.
2011-01-01License change: We are now AGPLv3+ instead of GPLv2+Harald Welte19-116/+97
The reason for this is quite simple: We want to make sure anyone running a customized version of OpenBSC to operate a network will have to release all custom modifiations to the source code.
2010-12-26SGSN: Avoid duplicate MM contexts in case MS and SGSN disagree on P-TMSIHarald Welte2-0/+30
2010-12-26SGSN: Implement network-initiated PDP CTX DEACT when GGSN restartsHarald Welte3-4/+174
If the GGSN restarts, its restart counter will increase. We can detect that and accordingly release/delete all PDP contexts for that GGSN.
2010-12-26SGSN: some more commentsHarald Welte1-0/+4
2010-12-24SGSN / GMM: Only allow non-roaming IMSIsHarald Welte1-1/+10
As we do not yet use the HLR from the SGSN, we allow all MS to attach to our GPRS network. However, if this is running in a public environment, it could cause service interruption to users of commercial GPRS networks. Thus, we now check if the first 5 digits of the IMSI match the MCC/MNC of the cell that they want to register to. Thus, any subscribers with SIM cards from real operators will no longer be accepted.
2010-12-23GPRS/GMM: Correctly look up MM Context in RA UpdateHarald Welte2-1/+19
If a MS changes RA, the RA will arrive in the new cell using the old TLLI (masked as foreign TLLI). So we need to look-up the TLLI in a special way, using the old RA as indicated in the 04.08 GMM message. There is still another bug remaining: As we somehow create a new LLC, the sequence numbers of our responses start from 0 again, which is not what the MS expects. This needs to be fixed in a follow-up patch.
2010-12-12Add mandatory routeing area IE to SUSPEND-NACKDieter Spaar1-1/+5
2010-11-15misc: Introduce a --enable-coverage mode to build with gprof coverageHolger Hans Peter Freyther1-2/+2
This adds a test coverage build. One can use gcov and lcov on the resulting data afterwards to see which code paths were executed and which were not.
2010-10-06misc: Once again go from "On Waves" to "On-Waves"..Holger Hans Peter Freyther4-4/+4
Try to get the company name of our sponsor right...
2010-09-11vty: Use \r\n in the copyright messagesHolger Hans Peter Freyther2-8/+8
We should use VTY_NEWLINE but our strings are static, always use \r\n as unix terminals can handle that as well.
2010-09-04vty: Add the config node code to everyone.Holger Hans Peter Freyther2-0/+2
2010-08-27[gprs] Add option parsing to SGSNHarald Welte1-1/+75
2010-08-25Introduce '-D' commandline option to daemonize processesHarald Welte1-1/+16
This uses the osmo_daemonize() function of libosmocore >= 0.1.18, and is now implemented for bac_nat, osmo-bsc, bsc_hack, osmo-gbproxy and bsc_mgcp. This means only osmo-sgsn is missing, which currently has no option parsing at all.
2010-08-24Add gprs_sndcp.h to noinst_HEADERSHarald Welte1-0/+1
2010-08-09[GPRS NS] Fix memory leak in gprs_ns_sendmsg() error pathHarald Welte1-0/+4
When gprs_ns_sendmsg() succeeds in sending the message, we free()d the msgb after transmitting it on the socket. However, if the NS-VC is blocked or some other error condition exists, we returned an error code but didn't free the msgb. This resulted in an error leak which is now being addressed.
2010-07-23[gprs] BSSGP: Fix null pointer dereferenceHarald Welte1-2/+3
Zecke has found this using "make CC="clang --analyze"
2010-07-03gprs/llc: Don't check FCS in gprs_llc_hdr_dumpSylvain Munaut1-2/+2
The FCS isn't computed yet (because of ciphering). It _will_ be tested and reported as wrong later in the code so we can just display it here and let the latter code report the error if any. Signed-off-by: Sylvain Munaut <tnt@246tNt.com>
2010-07-03[SGSN] Some IEs in ATTACH REQUEST can be longer in 24.008Harald Welte1-1/+3
The original length checks were based on 04.08, but 24.008 allows longer IEs.
2010-07-03[SGSN] Initial work on GMM authentication and cipheringHarald Welte1-9/+103
2010-07-02[SGSN] LLC: only copy Kc if algorithm != GPRS_ALGO_GEA0Harald Welte1-1/+2
The caller currently has set the Kc pointer to NULL, this fix avoids crashing at the callee.
2010-07-02[SGSN] use GPRS_ALGO_GEA0 instead of '0'Harald Welte1-6/+11
2010-07-02[SGSN] LLC: Make sure we calculate FCS after decryptionHarald Welte1-10/+5
2010-07-02[SGSN] Use libosmocore GPRS encryption plugins from LLC layerHarald Welte1-8/+88
This adds the bits that call into libosmocore (and its plugins) to implement GPRS (LLC) encryption.
2010-07-02[SGSN] Call libosmocore helper to load cipher pluginsHarald Welte2-0/+8
2010-07-02[SGSN] remove bogus debug statementHarald Welte1-1/+0
