File src/bitvec.c:

https://gerrit.osmocom.org/c/libosmocore/+/26308/1/src/bitvec.c@485 
PS1, Line 485: 	if (len && bytenum_from_bitnum(*read_index + len - 1) >= bv->data_len) {
why this -1?


https://gerrit.osmocom.org/c/libosmocore/+/26308/1/src/bitvec.c@494 
PS1, Line 494: 		int bit = bitvec_get_bit_pos((const struct bitvec *)bv, bv->cur_bit);
I'd rather still keep the error checking here.
