Please add a much more detailed commit message explaining the background
to this, what the test case does and why your fix is the right one, why
using SO_RCVTIMEO wasn't good enough, etc. Also fix the summary line not
to have a "BlueZ" prefix (that should be within the initial []) and the
form of the first word should be "Add" and not "Added" (actually since
this entire patch seems to be a fix it should be "Fix ...").

We don't use this for user space patches.

Please use the _seconds variant of the GLib timeout functions.

Don't use char for integer variables. int, guint etc. would be more
appropriate here.

I'd call this timeout_source (it's already within a struct called
network_conn so you don't need a conn prefix).

I suppose this should also set the source back to 0?

Does this really need to be inline? Have you done some profiling to
determine that it's really needed and has a huge impact? If not just
leave the "inline" bit out.

Please keep this variable.

..and don't do the get_fd() call within the parameters of another
function call. Also, why not use write() since you're anyway passing 0
as the flags (I know the original code was using send so this is a minor
issue). Also the above line looks like it's breaking the 80 character
rule.

No explicit type casts for void pointer please.

Looks like you're breaking the 80 character rule for the first error
call. Also, the coding style should be "} else {" on one line.

Split this up:
err = foo();
if (err < 0)
return err;
> + nc->con_to_src = g_timeout_add(CON_SETUP_TO_MS, bnep_conn_req_to, nc);
And this one (like I mentioned previously) should use the _seconds
variant.

Hi Johan,
Thanks for the review, I will send patch v2 shortly.
