![]() 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. The test's expectation shall be corrected along with the bug fix in a subsequent commit.
