* write_queue: Use EBADF instead of EBABDFD for portabilityHolger Hans Peter Freyther2014-07-013-5/+5

* write_queue: Avoid possible use-after-free if fd is read-/writableDaniel Willmann2014-06-221-5/+18
| | | | | | | | | If the FD is both readable and writable and the read callback closes the connection (and frees the surrounding structure) we shouldn't call the write callback (or check anything else in the read fd). With this patch callback functions can return -EBADFD if they don't want the FD to be handled any more.
* update TS 08.08 header + TLV definitions to TS 48.008 / 11.7.0Harald Welte2014-06-212-18/+151
| | | | | | | | | | 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.

* gsm0411_smr: Fix the size of the arrayHolger Hans Peter Freyther2014-05-231-1/+1

* Fix introducing osmocom speficic OML attributesHarald Welte2014-05-193-1/+11
| | | | | | | | | | | | | | | | | | | 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)

* Merge remote-tracking branch 'daniel/lapdm-desync'Holger Hans Peter Freyther2014-03-268-12/+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.
| * gsm/lapdm: Prevent LAPD tx_queue from filling up in polling modeDaniel Willmann2014-03-266-17/+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.

| * ladpm: Fix msgb handling and SAPI=3 establishment delayJacob Erlbeck2014-03-103-31/+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.

| * lapd/test: Check for empty ACCH queue, tooJacob Erlbeck2014-03-041-0/+2

| * lapd/test: Extend test case to test msgs having data before l2hJacob Erlbeck2014-03-042-4/+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.

| * lapd/test: Show dequeued messagesJacob Erlbeck2014-03-042-32/+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.
| * msgb: Add msgb_hexdump() functionJacob Erlbeck2014-03-042-0/+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

* sms: Fix gsm_7bit legacy functions return valueJacob Erlbeck2014-01-094-6/+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
