* ipa: rename functions for consistencyHarald Welte2014-08-202-13/+13
| | | | | | | | As we are breaking builds by moving functions from libosmo-abis to libosmocore anyway, we might as well give functions more appropriate names. ipaccess is a company, while IPA is the multiplex protocol, and CCM is the protocol used for establishing identities on the IPA multiplex.
* import various generic IPA related functions from libosmo-abisHarald Welte2014-08-202-0/+63
| | | | | | | | | libosmo-abis is about forming A-bis interfaces/lines by means of E1 or the IPA multiplex (or possibly other link layers). The IPA multiplex is used in other contexts, such as the Control interface, or the A interface. In that context, it makes sense to have generic IPA related functions in libosmocore.

* update TS 08.08 header + TLV definitions to TS 48.008 / 11.7.0Harald Welte2014-06-211-2/+2
| | | | | | | | | | This adds support for A-over-IP and LCLS related message/IEI definitions. Old definitions are in decimal, which is very hard (at least for me) to compare with the binary tables in the spec. Hex is much easier to manually compare for completeness/correctness. I didn't touch the existing definitions, but think they should move to hex, too.

* Fix introducing osmocom speficic OML attributesHarald Welte2014-05-191-1/+3
| | | | | | | | | | | | | | | | | | | Rename NM_ATT_O_REDUCEPOWER to NM_ATT_OSMO_REDUCEPOWER, which makes it more clear that this is an osmcoom specific attribute. Also, we cannot simply overload 0x01 as an already defined OML attribute. The problem is quite simple: When we use abis_nm_att_tlvdef during the TLV parse, 0x01 will match to NM_ATT_ABIS_CHANNEL, which is defined as { TLV_TYPE_FIXED, 3 }. So instead, we need to introduce a new abis_nm_osmo_att_tlvdef[], which has to be patched into abis_nm_att_tlvdef[] by the means of tlv_def_patch(), exactly how we do it for bs-11 and nanobts specific attributes. I'm using 0xfe for the attribute, as 0xfe doesn't overlap with the IPA specific attribues (and we might want to combine/merge the 12.21 plus IPA plus osmocom spefici attributes)

* gsm/lapdm: Prevent LAPD tx_queue from filling up in polling modeDaniel Willmann2014-03-261-0/+1
| | | | | | | If LAPDm receives an I-Frame while there already is an I-Frame in the tx_queue the code generates an additional RR (to acknowledge the received I-Frame). Instead, N(R) of the I-Frame in the tx_queue should be updated to ACK the data.

* ladpm: Fix msgb handling and SAPI=3 establishment delayJacob Erlbeck2014-03-101-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it takes 3s to establish a SAPI 3 SACCH connection with osmo-bts. This is due to the fact, that a broken SABME request is sent first and and is ignored by the MS. Then, after a T200 timeout (2s) the SABME command is sent again (this time correctly) and answered by the MS. The first SABME message is broken (it has a length field of 3 and ends with 3 bytes from the tail of the original RSL message), because of it is expected throughout lapdm.c that msg buffers containing RSL have msg->l2h == msg->data. Some abis input drivers fulfill this but IPA doesn't, thus the 3 bytes of the IPA header are still part of the msg and confuse length computation. Since internal fields of the msg are modified directly, this is difficult to see. This patch adds a new function msgb_pull_to_l3() that explicitely skips over all headers prepending L3 and therefore resets l1h and l2h. This function is then used instead of msgb_pull_l2h() which only worked correctly when msg->l2h == msg->data. In addition, code manipulating msg->tail and msg->len directly has been replaced by calls to msgb_trim(). Note that this patch does not fix all issues of this case in the LADP related code.

* msgb: Add msgb_hexdump() functionJacob Erlbeck2014-03-041-0/+1
| | | | | | | | | | | | This function works like osmo_hexdump() and returns a static buffer containing hex bytes along with markers for the layers. Note that it uses osmo_hexdump() internally, thus a call to msgb_hexdump() invalidates the buffer that has been returned by an earlier call to osmo_hexdump(). In short: don't mix them in a single call printf(). Sponsored-by: On-Waves ehf
* sms: Fix gsm_7bit legacy functions return valueJacob Erlbeck2014-01-091-0/+3
| | | | | | | | | | | | | | The legacy 7bit conversion functions (those without the '_n_' in the name) gave wrong return values on 64 bit platforms due to unproper signed/unsigned conversions and the usage of SIZE_MAX. This patch fixes this by using a smaller max size (see GSM_7BIT_LEGACY_MAX_BUFFER_SIZE, currently set to 64k) for the legacy wrappers and by using unsigned int for max_septets. In addition, there are tests now that check the return values of legacy encoding and decoding. Sponsored-by: On-Waves ehf

* gb: Fix NS RESET/RESET_ACK abnormal casesJacob Erlbeck2013-10-241-0/+5
| | | | | | | | | | | | | | | | This changes the implementations for the reception of RESET and RESET_ACK to be compatible with 3GPP TS 08.16, 7.3.1: - Just send a RESET_ACK with correct values back to the SGSN when a RESET with an invalid NSVCI or NSEI has been received. - Check RESET_ACK for matching NSEI and NSVCI. - Ignore unexpected RESET_ACKs. In addition, use RESET_ACK from a BSS to update the BSS source address based on the NSVCI to be tolerant with changing UDP source addresses/ports. Sponsored-by: On-Waves ehf
* gb: Fix gprs_ns_rx_reset to not create NS-VC duplicatesJacob Erlbeck2013-10-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Under special circumstances (see below) receiving a NS-RESET leads to duplicated NS-VC entries. This happens when the source port of a NS-VC changes to a new one that has already been used by another NS-VC. This patch changes gprs_ns_rx_reset() to check for this case and to use the existing NS-VC object. The NS-VC object that was associated with the source address before is detached from this source but kept in the NS-VC list so that it can be reattached when a correspondent NS-RESET is received later on. Meanwhile it will have a cleared link layer address which will not match a real link info. A new counter NS_CTR_REPLACED is incremented each time when the NS-VC object is replacing another one. A new signal S_NS_REPLACED is added which gets dispatched in this case, too. Another new counter NS_CTR_NSEI_CHG is incremented each time when the NSEI of a NS-VC object (with fixed NSVCI) changes.

* vty: Make vty_event dispatch signals and use it in the testcaseHolger Hans Peter Freyther2013-10-102-0/+15
| | | | | | | | | The testcase didn't work on Ubuntu 12.04 because vty_create will directly call vty_event (e.g. not through the plt). This means that the approach to override vty_event in the testcase failed. Use the signal interface of libosmocore and make the testcase use it. The signals can be generally useful as well.
* gb: Separate nsvc creation from NS message processingJacob Erlbeck2013-10-081-0/+9
| | | | | | | | | | | | This patch refactors gprs_ns_rcvmsg() by moving the parts relevant to the NS messages into the new functions gprs_ns_vc_create() (nsvc object creation) and gprs_ns_process_msg() (main NS automaton). These do not contain code that directly depends on the link layer (they call other functions that still do). This reduces the gprs_ns_rcvmsg() function to calling these two functions and optionally setting up the link layer specific fields of the nsvc. Sponsored-by: On-Waves ehf

* core: Remove defined() check for OSMO_DEPRECATEJacob Erlbeck2013-08-151-11/+5
| | | | | | | | This reverts commit bf991bc0f3006eddf45d494ee7e476a75dbaf36e and fixes the bug instead. It's just sufficient to remove the defined() test, since identifiers that aren't macros are just considered as 0 when used with #if. (see cpp info page, section 4.2.2 'If' in cpp-4.6.info)
* core: Fix-up the OSMO_DEPRECATED for older compilersHolger Hans Peter Freyther2013-08-141-3/+9

* sms: Added result buffer size parameter to 7bit conv funsJacob Erlbeck2013-08-121-7/+52
| | | | | | | | | | | | | The 7bit<->8bit encoding/decoding functions didn't check whether there is still enough space in the destination buffer. Therefore a buffer size parameter has been added to each of the functions which is used to truncate the output if the buffer is too small. In addition, the return value of the decoding functions has been changed to number of characters written (excluding \0), so this value is always equal to strlen(decoded). The old functions are still available as wrapper functions.
* Add special 7-bit encoding and decoding functions for USSD codingAndreas Eversberg2013-08-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Handling 7-bit coding is a little different for USSD, as TS 03.38 states: To avoid the situation where the receiving entity confuses 7 binary zero pad bits as the @ character, the carriage return or <CR> character shall be used for padding in this situation [...]. If <CR> is intended to be the last character and the message (including the wanted <CR>) ends on an octet boundary, then another <CR> must be added together with a padding bit 0. The receiving entity will perform the carriage return function twice, but this will not result in misoperation as the definition of <CR> [...] is identical to the definition of <CR><CR>. The receiving entity shall remove the final <CR> character where the message ends on an octet boundary with <CR> as the last character. Jacob has verified the fix with fakeBTS and the wireshark dissector. Fixes: OW#947 Reviewed-by: Jacob Erlbeck <jerlbeck@sysmocom.de>
