23 years agoIt turns out that the read timeout in Solaris's "bufmod" STREAMS module
guy [Thu, 28 Dec 2000 01:44:19 +0000 (01:44 +0000)]
It turns out that the read timeout in Solaris's "bufmod" STREAMS module
doesn't work like the read timeout in BPF - the timer doesn't start
until at least one packet has arrived.

I think that's the way read timeouts should work on *all* packet capture
mechanisms, but it does mean that Solaris will, on a quiet net, exhibit
the same symptoms that Linux used to exhibit before we put in a
"select()" call to wait until either packets arrive or a timer expires -
the "pcap_dispatch()" call blocks until a packet arrives, so the display
doesn't get updated and Ethereal doesn't respond to user input until a
packet arrives.

Furthermore, Linux isn't the only OS that lacks any read timeout
on its packet capture mechanism; the others will also have that problem.

We therefore do the "select()" on *all* platforms other than the BSDs
(where the timer starts when the read is done, and can be used for
polling); I don't know whether it's necessary on Digital UNIX, but I
suspect it's necessary on SunOS 4.x (as the 5.x "bufmod" is probably
derived from the 4.x one, and the 5.x one, as per the above, starts the
timer when a packet arrives), and it may even be necessary on 3.x, those
(BSD, SunOS including 5.x, and Digital UNIX) apparently being the only
UNIXes that appear to have such a read timeout.
