2017-03-13bts.cpp: Fix overloading ambiguityMax2-6/+11
Fix error introduced in 1275a3f91a744e011b0dba82b09124d249c7abb5 by using signed 32 bit integer which is enough for Frame Number in GSM. Also, mark parameter constraints more explicitly: - add assert for expected FN values - don't perform computation for non-relative FN The error was: bts.cpp: In member function ‘uint32_t BTS::rfn_to_fn(uint32_t)’: bts.cpp:554:25: error: call of overloaded ‘abs(uint32_t)’ is ambiguous if (abs(rfn - m_cur_rfn) > RFN_THRESHOLD) { ^ In file included from /usr/include/c++/6/cstdlib:75:0, from /usr/include/c++/6/stdlib.h:36, from /usr/include/osmocom/core/linuxrbtree.h:97, from /usr/include/osmocom/core/timer.h:35, from ./bts.h:29, from bts.cpp:21: /usr/include/stdlib.h:735:12: note: candidate: int abs(int) extern int abs (int __x) __THROW __attribute__ ((__const__)) __wur; ^~~ In file included from /usr/include/c++/6/stdlib.h:36:0, from /usr/include/osmocom/core/linuxrbtree.h:97, from /usr/include/osmocom/core/timer.h:35, from ./bts.h:29, from bts.cpp:21: /usr/include/c++/6/cstdlib:185:3: note: candidate: __int128 std::abs(__int128) abs(__GLIBCXX_TYPE_INT_N_0 __x) { return __x >= 0 ? __x : -__x; } ^~~ /usr/include/c++/6/cstdlib:180:3: note: candidate: long long int std::abs(long long int) abs(long long __x) { return __builtin_llabs (__x); } ^~~ /usr/include/c++/6/cstdlib:172:3: note: candidate: long int std::abs(long int) abs(long __i) { return __builtin_labs(__i); } Change-Id: Ib6d895a97aa35414f245ea4406c6e78f1b4fb5b8
2017-03-05BTS: Convert relative frame numbers to absolute frame numbersPhilipp Maier2-14/+59
The implementation of the method rcv_rach() in class BTS, restores the absolute frame number of the incoming RACH-Request by using the relative frame number (RFn = Fn mod 42432) from the rach request and the already known internal absolute frame number m_cur_fn, which is continusly updated by the CCU interface. In some rare cases, a RACH request might be received by the BTS, a very short time before the frame number wraps in its 42432. Depending on the PCU location, RACH request might be received by the BSC, which forwards it to the PCU. It is then likely that, while the RACH request is being forwarded to the PCU, the PCU internal absolute frame number wraps before the RACH can be processed. The relative frame number from the rach request would then be interpreted as if it were received after the wrapping of the internal frame number modulos. This commit adds logic to detect and resolve this race condition. Also a unit test is added to check some cornercases. Change-Id: I74f00c11e5739d49f370ce6c357149e81d9aa759

2017-01-26BTS: accept also relative frame numbers with rach requstPhilipp1-0/+15
The rach request contains a relative frame number (Fn % 42432), while BTS::rcv_rach() accepts the full frame number only. Since the BTS is always aware of the full frame number this is not a problem. But for BSC co-located PCU schemes it is a problem since the rach request only contains the relative frame number as mentioned above. The pcu continusly receives frame number updates with the GSM time indication message. It is simple to re-calculate the full frame number from that information. This patch makes BTS::rcv_rach() compatible with relative frame numbers, while not breaking the compatibility for full frame numbers Change-Id: Iaa182d8d29c6a0f5fa06064c2eb48b21b1ba2775
2017-01-24Handle packet access reject during packet resource requestaravind sirsikar4-4/+57
When Packet resource request 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: I05ff25124b58905586caa0c0c37023d69724f121

2017-01-23Add compression support in EGPRS PUANsivasankari8-27/+500
This adds compression of bitmap in PUAN. The compressed bitmap is used only if the number of bits in the bitmap does not fit in the message and there is a gain after compression. The algorithm is part of libosmocore and so there is dependency on the libosmocore for compilation. The algorithm is tested on integration setup by forcing compression.

2016-09-15tbf_dl: factor out EGPRS DL window size calculationAravind Sirsikar3-14/+24
A subsequent patch needs to call this from gprs_rlcmac_tbf::update(), so to avoid code dup, put the calculation in a separate function. Related: OS#1808 Change-Id: I7c7777d43f843bbd3421503fc2a8600f148ca035
2016-09-15EGPRS: Fix issue with row 4 of Table 10.4.14a.1 of 44.060 version 7.27.0 ↵Aravind Sirsikar2-11/+12
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 Hofmeyr1-6/+5
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.
