[PATCH BlueZ 2/2] lib: Fix SDP_TEXT_STR16/SDP_URL_STR16 parsing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



sdp_extract_attr() uses the "size" parameter to return the number of
bytes consumed when parsing SDP Data Elements. This size is used to
advance a buffer pointer to parse next element.

This size was being incorrectly calculated for
SDP_TEXT_STR16/SDP_URL_STR16, where the string length was added twice.

A unit test added on the previous commit should now pass with this fix.
