[Bluez-devel] null bytes in 'SDP_TEXT_STR8' data element

["Raimund Steger" <rs@mytum.de>]

Hi,

I have problems adding a "TEXT" attribute value to a service
record that contains '0x00' bytes. First, it seems like the sdp_data_alloc()
function does use strlen() for text entries which will use these
bytes as string terminators.

Second, I use the JSR-82 library from Avetana, where the service record
gets registered via send_req_w4_rsp which seems to be null-byte safe.
However, when someone queries the record, the string element is again
truncated which seems to happen in the sdp_gen_pdu() function in
sdp/sdp.c [of bluez-libs-2.17], l. 686, where strlen() is used to
determine the string element's length. Would it be possible to use
d->unitSize in this place instead?

Thanks,

Raimund
