It's been deprecated since QEMU v3.1. We've explicitly asked in the
deprecation message that people should speak up on qemu-devel in case
they are still actively using the bluetooth part of QEMU, but nobody
ever replied that they are really still using it.
I've tried it on my own to use this bluetooth subsystem for one of my
guests, but I was also not able to get it running anymore: When I was
trying to pass-through a real bluetooth device, either the guest did
not see the device at all, or the guest crashed.
Even worse for the emulated device: When running
qemu-system-x86_64 -bt device:keyboard
QEMU crashes once you hit a key.
So it seems like the bluetooth stack is not only neglected, it is
completely bitrotten, as far as I can tell. The only attention that
this code got during the past years were some CVEs that have been
spotted there. So this code is a burden for the developers, without
any real benefit anymore. Time to remove it.
Note: hw/bt/Kconfig only gets cleared but not removed here yet.
Otherwise there is a problem with the *-softmmu/config-devices.mak.d
dependency files - they still contain a reference to this file which
gets evaluated first on some build hosts, before the file gets
properly recreated. To avoid breaking these builders, we still need
the file around for some time. It will get removed in a couple of
weeks instead.

Replace a large number of the fprintf(stderr, "*\n" calls with
error_report(). The functions were renamed with these commands and then
compiler issues where manually fixed.

Clang static analyzer reports a memory leak. Actually, the allocated
memory escapes here:
record->attribute_list[record->attributes].pair = data;
but clang is correct that the memory might leak if len is zero. We
know it isn't; assert that it is the case.
The craziness doesn't end there. The memory is freed by
bt_l2cap_sdp_close_ch:
g_free(sdp->service_list[i].attribute_list->pair);
which actually should have been written like this:
g_free(sdp->service_list[i].attribute_list[0].pair);
The attribute_list is sorted with qsort; but indeed the first
entry of attribute_list should point to "data" even after the qsort,
because the first record has id SDP_ATTR_RECORD_HANDLE, whose
numeric value is zero.
But hang on. The qsort function is
static int sdp_attributeid_compare(
const struct sdp_service_attribute_s *a,
const struct sdp_service_attribute_s *b)
{
return (int) b->attribute_id - a->attribute_id;
}
but no one ever writes attribute_id. So it only works if qsort is
stable, and who knows what else is broken, but we can fix it by
setting attribute_id in the while loop.

In the case of a 4-byte length, shifting a value by 24 may cause
an unintended sign extension when converting from int to size_t.
Use a uint32_t variable instead.

sdp_svc_match, sdp_attr_match and sdp_svc_attr_match read the last
argument. The only sensible way to change the code is to make that last
argument "len" instead of "seqlen" which is the length of a subsequence
in the previous "if" branch.
To make the structure of the code clearer, use "else" instead of
"else if".

The binary search in sdp_uuid_match() only works when the number of
elements to search is a power of two.
lo = record->uuid;
hi = record->uuids;
while (hi >>= 1)
if (lo[hi] <= val)
lo += hi;
return *lo == val;
I noticed that the record->uuids calculation in
sdp_service_record_build() was suspect:
record->uuids = 1 << ffs(record->uuids - 1);
Unlike most ffs(val) - 1 users, the expression is ffs(val - 1)!
Actually ffs() is the wrong function to use for power-of-2. Use
pow2ceil() to achieve the correct effect. Now the record->uuid[] array
is sized correctly and the binary search in sdp_uuid_match() should
work.
I'm not sure how to run/test this code.
