2014-03-26Merge remote-tracking branch 'daniel/lapdm-desync'Holger Hans Peter Freyther8-12/+300
This should fix long delays when sending a long SMS on an encrypted channel. It is the most minimal change to the polling mode. One option we discussed internally is to queue a higher level representation and generate the actual LAPDm frames later.
2014-03-26gsm/lapdm: Prevent LAPD tx_queue from filling up in polling modeDaniel Willmann6-17/+39
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.
2014-03-26tests/lapd: Add a testcase to check for LAPDm sync issuesDaniel Willmann2-9/+272
Regression test for LAPDm recording the current state
2014-03-26lapdm: Make lapdm_datalink_for_sapi publicDaniel Willmann3-3/+6
This API allows you to get the lapdm_datalink for a SAPI. It's needed in the lapdm_test, so make it public.

2014-03-16lapd: Improve log message and mention the SAPI the dl is onHolger Hans Peter Freyther1-2/+2
When debugging an issue that involves SAPI=0 and SAPI=3 the log file does not have enough context. Add the SAPI to this message so we at least understand which SAPI we are talking about.

2014-03-10ladpm: Fix msgb handling and SAPI=3 establishment delayJacob Erlbeck3-31/+33
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len directly has been replaced by calls to msgb_trim().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.

2014-03-04lapd/test: Check for empty ACCH queue, tooJacob Erlbeck1-0/+2
This just adds a single test to verify that the ACCH queue is actually empty. Sponsored-by: On-Waves ehf
2014-03-04lapd/test: Extend test case to test msgs having data before l2hJacob Erlbeck2-4/+16
Since e.g. the IPA input driver leaves it's specific header in front of msg->l2h, so that msg->l2h != msg->data. The lapdm code does not expect this at least in rslms_rx_rll_est_req(). This patch modifies the test program to add a dummy L1 header to generated messages (unless the test would abort when doing so). Note that the ok file reflects the current state which is not correct.

2014-03-04lapd/test: Show dequeued messagesJacob Erlbeck2-32/+72
This adds and uses a wrapper for lapdm_phsap_dequeue_prim() that prints information about the message that has been taken from the queue.
2014-03-04msgb: Add msgb_hexdump() functionJacob Erlbeck2-0/+50
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
2014-02-09lapd: Use the right struct for the talloc_zero_array callHolger Hans Peter Freyther1-2/+2
I saw this while playing with talloc pools and wondered why lapd_core is creating a log_info. Use the right struct for the array.

This test case processes RSL establish requests for SMS (SAPI 3) on the SDCCH and the SACCH channels. The TX queues are checked after processing each message. Ticket: SYS#192 Sponsored-by: On-Waves ehf

Currently w[14]/w[15] and w[18]/w[19] are swapped in range 256 format decoding in gsm48_decode_freq_list(). This patch fixes this. Sponsored-by: On-Waves ehf
2014-01-09sms: Fix gsm_7bit legacy functions return valueJacob Erlbeck4-6/+44
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
2014-01-02abis: Use the right return value for abis_nm_pchan4chcombHolger Hans Peter Freyther2-2/+2
abis_nm_pchan4chcomb will return a pchan for a given channel combination but returned a value of the channel combination. Fix it to return the physical channel combination. Fixes: Coverity CID 1040767
2014-01-02utils: Greatly improve performance of osmo_hexdump routinesNils O. Selåsdal2-6/+14
In the osmo-bts and libosmo-abis code the hexdump routine is used for every incoming/outgoing packet (including voice frames) and the usage of snprintf showed up inside profiles. There is a semantic change when more than 4096 characters are used. The code will now truncate at byte boundaries (and not nibbles). Code: static const int lengths[] = { 23, 1000, 52 }; char buf[4096]; int i; for (i = 0; i < 30000; ++i) char *res = osmo_hexdump(buf, lengths[i & 3]); Results: before: after: real 0m3.233s real 0m0.085s user 0m3.212s user 0m0.084s sys 0m0.000s sys 0m0.000s

The filter_fn has not been copied into the new structure breaking the imsi and other filters in OpenBSC. Looking at the code we should also introduce a callback for the reset of the context so we could use subscr_get/subscr_put on the subscriber structure.

2013-11-11gprs: Fix VTY NSVC initialisation bug by changing gprs_nsvc_create()Jacob Erlbeck1-3/+3
Currently the field nsvci_is_valid is set to 0 in the NSVC object returned by gprs_nsvc_create(). This was a semantic change probably introduced by commit 5e6d679d. As a result, NSVC created via the VTY have this flag set to 0 causing RESET_ACK messages to be rejected. This patch changes the default behaviour of gprs_nsvc_create() to always set this flag. So it must be set to 0 explicitely if needed which is more intuitive and thus less error prone. It fixes breaking connections from the Gbproxy to the SGSN. Ticket: OW#874 Sponsored-by: On-Waves ehf

2013-10-30gprs: Ignore NS RESET_ACK and ALIVE_ACK without RESETJacob Erlbeck2-6/+17
Currently those messages are answered by a NS_STATUS message when received on an uninitialised (no NS_RESET hat been seen yet) NS_VC which violates GPP TS 08.16 7.3.1 and 7.4.1. This patch adds checks to gprs_ns_vc_create() and eventually returns before the error NS_STATUS message is generated. Sponsored-by: On-Waves ehf

Several messages shall not be answered when a RESET hasn't been received on a NS-VC: - NS_RESET_ACK (see 3GPP TS 08.16, 7.3.1) - NS_ALIVE_ACK (see 3GPP TS 08.16, 7.4.1) - NS_STATUS (see 3GPP TS 08.16, 7.5.1) Sponsored-by: On-Waves ehf
2013-10-26lapd: Extend the test to check if lapdm_channel_exit is idempotentHolger Hans Peter Freyther1-0/+10
I have a crash with an older libosmocore and the sysmobts. I am not sure how we can have a release for a channel where the lapdm_channel has not gone through lapdm_channel_init. But to prevent the crash we can promise lapdm_channel_exit to be idempotent. It has been idempotent since f5a079f739c57d8be7c59149fd45475c402a45fc

2013-10-24gb: Create new NSVC object instead of patching the NSVCIJacob Erlbeck3-16/+40
When a RESET is received on the same link with a different NSVCI from a BSS on a dynamically created NS connection do not patch the nsvc object but create a new one instead. Thus the NSVCI is never modified at a nsvc object after the NS-VC has been established. Sponsored-by: On-Waves ehf
2013-10-24gb: Fix RESET handling with changing NSEIJacob Erlbeck2-50/+67
This modifies the NS stack's behavior to accept RESET and RESET_ACK NSEI changes for NS-VC dynamically created by RESET messages from BSSes. This feature is not used for NS-VC configured via VTY or NS-VC to a SGSN. Sponsored-by: On-Waves ehf
2013-10-24gb: Fix NS RESET/RESET_ACK abnormal casesJacob Erlbeck4-157/+294
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
2013-10-24gb: Add test cases for NS RESET proceduresJacob Erlbeck2-0/+703
Add a test handling proper and mismatching RESETs. The latter may occur, when ports change within a NS-VC without the SGSN getting notice. This tests for the behavior of the NS protocol stack for RESET and RESET_ACK messages which changing/invalid NSEI and NSVCI like it is being described in 3GPP TS 08.16, 7.3.1.
