* signal: add SS_L_NS as a signal subsystem for NS code in libosmo-gbHarald Welte2012-06-161-0/+1

* VTY: safe version of printing VTY welcome messageHarald Welte2012-06-032-19/+11
| | | | | | | | | | | | | | | | | | | | The old method used raw writes to the telnet FD, which is bad for several reasons: a) we don't know if we can actually write that many bytes to the socket at the given time b) the socket is still in blocking mode, so we could stall the entire process c) there may be weird interaction with the buffered writes of the vty_out Now, the print_welcome() functionality has moved to vty_hello() instead, where we can use normal vty_out() in buffered mode. This commit is expected to fix the garbled welcome message on arm-eglibc targets. It might still be a good idea to migrate the entire telnet interface to libtelnet - but at some later time ;)
* src/codec: Fix typo in MakefileSylvain Munaut2012-05-141-1/+1

* LAPDm: Ensure there is no payload in DISC framesHarald Welte2012-04-261-1/+6
| | | | | | When we send DISC frames (especially generated from RSL), we don't want any remaining bytes from the RSL message showing up as bogus DISC payload.

* sync prototype of osmo_sockaddr_is_local with declarationHarald Welte2012-04-081-1/+1
| | | | | in e476442cf0e84c65565ace545f5b73602b5f0ffc we changed from sockle_t to unsigned int, but only in the header, not in the implementation!
* timer: Increase the imprecision we accept in this testHolger Hans Peter Freyther2012-04-052-2/+2
| | | | | | On a loaded server we might not be able to reach 10ms precision in the test configuration and this is not a high precision timer anyway.
* libosmogsm: Add tvlv_att_def to exported symbolsHarald Welte2012-04-051-0/+1

* misc: Fix make distcheck, add the new libosmogsm.map file to the tarballHolger Hans Peter Freyther2012-04-051-0/+2

* lapdm: fix RSL message format in RLL ERROR INDICATIONHarald Welte2012-04-051-1/+0
| | | | | | In rsl_rll_error() we don't need to re-set the msg->l2h as that would corrupt the message. The recipient would interpret any cause value as 0.
* libosmogsm: Introduce explicit list of exported symbolsHarald Welte2012-04-044-3/+234
| | | | | | | | There is now a "libosmogsm.map" file containing an explicit list of to-be-exported symbols. This should prevent us from leaking non-static symbols into the global namespace. A similar scheme should be adopted by all other osmocom libraries
* vty: Add a function to write the current config to a file.Holger Hans Peter Freyther2012-03-282-46/+133

* osmo-auc-gen: Add mode for verifying user-supplied AUTSHarald Welte2012-03-221-14/+25
| | | | | When -A is used on the command line, the respective AUTS value will be validated and the SQN of the UICC printed.

* gsmtap: Add GSMTAP_GPRS_CS() / GSMTAP_GPRS_MCS()Harald Welte2012-02-081-0/+8
| | | | | | | | As requested by Mike Morrin <Mike.Morrin@ipaccess.com>, we introduce GSMTAP sub-types for all the different GPRS and EGPRS coding schemes. This is neccessary due to the fact that the RLC PDU doesn't contain any explicit indication of the coding scheme used on the radio layer.
* libosmocore/gsm: Fixed total size of gsm48_req_refAndreas Eversberg2012-02-071-3/+3
| | | | | "__attribute ((packed))" must be defined for unions, in order to make sure that the compiler packs unions.
* GSM 08.08: change gsm0808_create_classmark_update() prototypeHarald Welte2012-01-263-7/+19
| | | | | The caller explicitly specifies CM2 and CM3, rather than one blob containing both.
* GSM 08.08: Cleanup the code, remove lots of magic hard-coded numbersHarald Welte2012-01-261-116/+60
| | | | | | | Rather than manually hard-coding numbers and using byte-arrays, we use the msgb_*_{push,put}() function family of libosmocore/libosmogsm. This is currently untested.
* gsmtap: make sure we agree with wireshark on GSMTAP channel typesHarald Welte2012-01-261-2/+2

* TLV/msgb: Return first byte of newly-pushed data from msgb_*_push()Harald Welte2012-01-221-14/+28
| | | | | The msgb_*_push() functions erroneously returned the firsrt byte after newly-pushed information, which makes no sense at all.
* tests: Introduce a very basic gsm0808 testHolger Hans Peter Freyther2012-01-227-1/+291
| | | | | | This tests verifies the content of the GSM 08.08 messages, it does not verify the remaining headroom (which the SCCP/IPA code relies on being plenty to prepend the header). More to come in the future.
* msgb_trim(): actually trim to an absolute length, as the comment statesHarald Welte2012-01-141-5/+3
| | | | | The previous commit introduced a new msgb_trim() but the implementation differed from the specification.
* msgb: introduce msgb_trim() and msgb_l3trim() to trim msgb'sHarald Welte2012-01-141-0/+28

| * lapdm: Make sure that the msgb_l3len(msg) == length...Holger Hans Peter Freyther2012-01-123-13/+17
| | | | | | | | | | | | | | | | | | | | This code should not play with the internals of the msgb like this, this code got introduced in af48bed55607931307 and is breaking the osmo-bts usecase of forwarding an RSL message. Add a test case that fails without the new code. I would prefer if we could get rid of the manipulating the msgb like this, it is prone to errors like this one.
| * lapd: Warn if someone attempts to send an empty messageHolger Hans Peter Freyther2012-01-122-0/+22
| | | | | | | | | | | | DATA REQ with a msgb_l3len(msg) == 0 message does not make any sense, log an error and return immediately before attempting to send an empty I frame in lapd_send_i.
| * lapd: Mention the L3 size of the payload being sentHolger Hans Peter Freyther2012-01-121-1/+2

* libosmocore/lapd: Fixed handling of sequence errors at lapd_core.cAndreas.Eversberg2012-01-101-3/+21
| | | | | | | | | | | | | | | If a sequence error is received, the N(R) variable must still be used to acknowledge previously transmitted frames. If there are two subsequent sequence errors received, ignore it. (Ignore every second subsequent error.) This happens if our reply with the REJ is too slow, so the remote gets a T200 timeout and sends another frame with a sequence error. Test showed that replying with two subsequent REJ messages could the remote L2 process to abort. Replying too slow shouldn't happen, but may happen over serial link between BB and LAPD.

* Fix generation of GPRS Routing Area in case of 3-digit MNCGus Bourg2011-12-141-1/+1
| | | | | This fixes a simple typo that causes erroneous GPRS Routing Area encoding if you use 3-digit MNCs.
* lapd: Disable one part of the test as it fails on FreeBSDHolger Hans Peter Freyther2011-12-121-1/+2
| | | | | I thought this number would be wrong in the same way but it depends on OS/ARCH. Disable this part of the test for now.
* lapd_test: Look at the content of LAPD messages and compare themHolger Hans Peter Freyther2011-12-122-16/+61
| | | | Verify the output, accept two known errors in the generation of it.
* lapdm: Create a simple test case to transmit data between both endsHolger Hans Peter Freyther2011-12-117-1/+294
| | | | | | | This is testing the establishment of two ends (BTS, MS) one is in the polling mode as used by osmo-bts. Transfer data between the two ends. The sent data is not verified though. This should be followed up soon.
* auth_core: add missing string.h include to reduce warningsHarald Welte2011-12-071-0/+1

* auth_core: don't use anonymous unions to make certain gcc versions happyHarald Welte2011-12-075-20/+20

* add 'osmo-auc-gen' tool that can be used to generate auth vectorsHarald Welte2011-12-072-1/+187
| | | | | | Thsi tool usses libosmocore in order to generate 2G and 3G authentication vectors from private key material, exactly like an AuC would produce them in a real network.
* auth_core: Make sure we always save the RAND in the vectorHarald Welte2011-12-071-1/+8
