2016-11-17Install the pcuif_proto.h header fileHarald Welte7-5/+10
So far, we used to keep a copy of the header file around in both osmo-pcu and osmo-bts projects. Before we start introducing a third copy in openbsc, let's have the osmo-pcu install the header file and make the other programs use that. Change-Id: I60976c9be5488256d1ff55fdc5aa548e3705400d
2016-11-17Fix GSMTAP logging in case direct PHY access is enabledHarald Welte1-2/+2
In the existing code, GSMTAP messages were only generated in case no direct PHY access was being used (i.e. in the case all user traffic goes over the PCU socket). I'm not quite sure what the reason is for that would be and conclud this is not intentional. Let's first send the message to GSMTAP and then decide whether to send it via the direct PHY access or via the PCU socket into the BTS/BSC. Change-Id: I5d2e018f7009cb947abc874881c0c440feca3ade

2016-11-11Handle packet access reject during EPDAN/PDAN with channel descriptionaravind sirsikar9-12/+135
When PDAN/EPDAN with channel description is received, PCU will generate the packet access reject if no resources are present. The encoding is done based on section 7.1.3.2.1 and 8.1.2.5 of 44.060 version 7.27.0 Release 7. This patch also includes the test case to validate the generated packet access reject message. This patch is integration tested on Osmo-trx setup with Ettus B210 board and LG F70 MS with some simulation code changes in Osmo-pcu. Change-Id: I096a3bb44a65533b9e9b091925dd5f70a8696d6

2016-11-02EGPRS: fix for EPDAN out of windowaravind sirsikar4-37/+134
Fix alignment of EPDAN outside the RLC transmit window, according to section 9.1.8.2.4 in 44.060 version 7.27.0 Release 7. The specification explains that a bit within the uncompressed bitmap whose corresponding BSN is not within the transmit window shall be ignored. Without this fix PCU was dropping the EPDAN message and not updating the status of BSNs which are inside the RLC window. This patch updates the status of the BSNs which are inside the window and ignores the remaining bits. Related: OS#1789 Change-Id: Id07d178970f168f5389016c1eea31eb6b82057b6

2016-10-30EGPRS: add test case to show EPDAN BSN out of window bugaravind sirsikar3-0/+140
This patch adds a test case test_tbf_epdan_out_of_rx_window, which expects a current bug with EPDAN for interpretation of the bitmap explained in section 9.1.8.2.4 in 44.060 version 7.27.0 Release 7. The specification explains that a bit within the uncompressed bitmap whose corresponding BSN is not within the transmit window shall be ignored. But current PCU implementation drops the EPDAN and does not update status of the BSN which are inside the window. The test's expectation is corrected along with the bug fix in a subsequent commit.

This reverts commit f1a7b8fc6651f92a8b7f3f27b7ca05d07f4e44e0. Conflicts: tests/tbf/TbfTest.err The commit broke GPRS service at least for osmo-bts-sysmo on a SysmoBTS 1002 with current master of osmo-bts (ef30f50d5d6d5f863fc147d05ccdceb89284934e). The error observed is the following log output (was viewing both osmo-bts-sysmo and osmo-pcu logs interleaved): <0002> tbf.cpp:874 TBF(TFI=0 TLLI=0x00000000 DIR=UL STATE=WAIT ASSIGN) T3169 timeout during transsmission <0002> tbf.cpp:893 - Assignment was on CCCH <0002> tbf.cpp:899 - No uplink data received yet <0007> l1sap.c:904 RACH for packet access <0001> pcu_l1_if.cpp:311 RACH request received: sapi=1 qta=0, ra=121, fn=13653 [repeat] When removing this single commit from current osmo-pcu master, GPRS service works well on SysmoBTS, with current osmo-bts master.

2016-10-18tbf: add llc_queue_size() to check llc_queue is valid before calling size()Alexander Couzens3-6/+15
gcc6 is optimizing if (!this) {CODE} as this is assumed to never be a std::nullptr here. Move the null check to the caller. In preparation of removing the check within llc_queue->size(), all callers must check the object before calling it. Make sure of that: make the llc_queue() access function protected and offer only a public llc_queue_size() function that incorporates the NULL check. All current callers are only interested in the llc_queue_size(). Tweaked-by: nhofmeyr Change-Id: I88cc3180f8f86785e3f07981895dabddf50b60a2
2016-10-17EGPRS: Add EPDAN CRBB Tree based decodingPravin Kumarvel9-15/+787
Implemented tree based algorithm to decode compressed bitmap in EPDAN as described in section 9.1.10 of 3GPP 44.060. This algorithm intends to improve the performance over existing method. New Regression test is added under bitcomp directory. Test case is added to validate decompressed result of the bitmap Present in EPDAN. Test is done for multiple bitmaps of varying length.

2016-09-15EGPRS: Fix issue with row 4 of Table 10.4.14a.1 of 44.060 version 7.27.0 ↵Aravind Sirsikar5-31/+24
Release 7 row 4 of Table 10.4.14a.1 of Spec 44.060 version 7.27.0 Release 7. Says "The previous RLC data block contains a Upper Layer PDU, or a part of it, that fills precisely the previous data block and for which there is no length indicator in that RLC data block. The current RLC data block contains a Upper Layer PDU that either fills the current RLC data block precisely or continues in the next RLC data block." So when we receive block with 1st LI: value=0 and Value of E bit in the same octet as 1, we expect 2 chunks with 1st chunk as length as 0 and complete and 2nd chunk as length non zero. But with this bug we see only 1 chunk causing incorrect assembling This issue has been fixed in this patch. Related: OS#1811 Change-Id: I2cd0fca3ed28a553ede3f4b8a7d3267284dd2c9b

2016-09-14Fix CSN1 decoding: CSN_LEFT_ALIGNED_VAR_BMP boundsNeels Hofmeyr2-12/+6
Fix attempted read past vector boundaries in case of a starting bit offset != 0, so that the last amount of bits read should be < 8. In the case of CSN_LEFT_ALIGNED_VAR_BMP, the mod-8 calculation was flawed, and in the final step, 8 bits were read instead of the remainder < 8. This lead to -EINVAL being returned by bitvec_get_bit_pos() and bogus resulting data. Instead, read 8 bits only as long as at least 8 bits remain, and read any remaining bits < 8 in a final step. Drop unneeded nB1 variable and an obvious comment. Adjust the unit test assertion in testCsnLeftAlignedVarBmpBounds() in RLCMACTest.cpp. Based on a fix by Aravind Sirsikar <Arvind.Sirsikar@radisys.com>, but implemented differently.

2016-09-14CSN1 decoding: add test to show bug in CSN_LEFT_ALIGNED_VAR_BMPAravind Sirsikar1-1/+22
CSN1 decoding currently contains an attempted read past vector boundaries in case of a starting bit offset != 0, so that the last amount of bits read should be < 8. In the case of CSN_LEFT_ALIGNED_VAR_BMP, the mod-8 calculation is flawed, and in what should be the final step of reading n < 8 bits, 8 bits are read instead of n (with an extraneous read of n bits following after that). This leads to -EINVAL being returned by bitvec_get_bit_pos() and bogus resulting data. Add testCsnLeftAlignedVarBmpBounds() in RLCMACTest.cpp to show and expect this bug.
