bt dev questions

[Alex Samorukov]

Hi all

I ported to FreeBSD anyRemote utility
(http://anyremote.sourceforge.net/), and while porting I got some issues
which i`m not able to resolve myself.
They are not critical (program is working), but a bit annoying.

1) Why sdpd require root permission to open session? As for me it`s
enough to check use file permissions on control socket. In Linux its
possible to register service w/o root permissions, so in ported version
I need to run it as root and then setuid to normal user.  What is the
reason for this?
2) I was not able to find how to change provider name and server
description in SDP_SERVICE_CLASS_SERIAL_PORT profile. anyRemote using
usual serial over bluetooth, but with changed service name field. I
found howto change channel (server_channel) but not description. Is it
possible at all?

I`m planning to submit my patches to the ports tree at nearest time.

to have better control over what services are offered. basically, i do
not want to have any random application go and register bunch of
non-existent services. requiring 'root' permission is may be a little
bit excessive, but its easy to fix. could teach sdpd to accept
connections from specified group (or even list of groups/users).

Yes, i think that its enough to have group, with sdpd r/w permission.
Because I don`t like setgid/setuid, and this will allow to avoid this in
bt services.

Thank you too. Author answered that he will include my patches to the
next version, so soon anyRemote will work in freebsd out of the box.
