[PATCH] Fix issue in encoding CSN_RECURSIVE_ARRAY

The remaining_bits_len is correctly decremented while encoding CSN_RECURSIVE_ARRAY for fixing the bug. Details of the bug is in https://projects.osmocom.org/issues/1641 During introduction of basic EGPRS feature new hex dump message PUASS, from a different working network log was used in Unit test. It exposed the issue of incorrect handling of recursive array encoding in osmo-pcu. --- src/csn1.cpp | 1 + tests/rlcmac/RLCMACTest.cpp | 1 + tests/rlcmac/RLCMACTest.ok | 8 ++++++++ 3 files changed, 10 insertions(+) diff --git a/src/csn1.cpp b/src/csn1.cpp index 82bf17f..d51fe83 100644 --- a/src/csn1.cpp +++ b/src/csn1.cpp @@ -2504,6 +2504,7 @@ gint16 csnStreamEncoder(csnStream_t* ar, const CSN_DESCR* pDescr, bitvec *vector bitvec_write_field(vector, writeIndex, !Tag, 1); LOGPC(DCSN1, LOGL_NOTICE, "%s = %u | ", pDescr->sz , (unsigned)(!Tag)); bit_offset++; + remaining_bits_len--; pDescr++; break; diff --git a/tests/rlcmac/RLCMACTest.cpp b/tests/rlcmac/RLCMACTest.cpp index 26d35ec..466b89e 100644 --- a/tests/rlcmac/RLCMACTest.cpp +++ b/tests/rlcmac/RLCMACTest.cpp @@ -93,6 +93,7 @@ void testRlcMacDownlink() "47240c00400000000000000079eb2ac9402b2b2b2b2b2b", // Packet Uplink Ack Nack "47283c367513ba333004242b2b2b2b2b2b2b2b2b2b2b2b", // Packet Uplink Assignment "400820001a3904df0680efb3300b2b2b2b2b2b2b2b2b2b", // Packet Downlink Assignment (EGPRS) + "40284f0000001009810c826f4406809dcecb2b2b2b2b2b", // Packet Uplink Assignment (EGPRS) "4024030f2f0000000087b0042b2b2b2b2b2b2b2b2b2b2b" // Packet Uplink Ack Nack (EGPRS) "4913e00850884013a8048b2b2b2b2b2b2b2b2b2b2b2b2b" "412430007fffffffffffffffefd19c7ba12b2b2b2b2b2b" diff --git a/tests/rlcmac/RLCMACTest.ok b/tests/rlcmac/RLCMACTest.ok index 4deced7..896982d 100644 --- a/tests/rlcmac/RLCMACTest.ok +++ b/tests/rlcmac/RLCMACTest.ok @@ -39,6 +39,14 @@ vector1 = 4082001a394df680efb330b2b2b2b2b2b2b2b2b2b vector1 = 4082001a394df680efb330b2b2b2b2b2b2b2b2b2b vector2 = 4082001a394df680efb330b2b2b2b2b2b2b2b2b2b vector1 == vector2 : TRUE +vector1 = 40284f00010981c826f446809dcecb2b2b2b2b2b +=========Start DECODE=========== ++++++++++Finish DECODE++++++++++ +=========Start ENCODE============= ++++++++++Finish ENCODE+++++++++++ +vector1 = 40284f00010981c826f446809dcecb2b2b2b2b2b +vector2 = 40284f00010981c826f446809dcecb2b2b2b2b2b +vector1 == vector2 : TRUE vector1 = 40243f2f000087b042b2b2b2b2b2b2b2b2b2b2b =========Start DECODE=========== +++++++++Finish DECODE++++++++++ -- 1.7.9.5
