72844 - Necko opens 2 TCP connections to self at startup

Status: VERIFIED DUPLICATE of bug 100154

(NSPR :: NSPR, defect)

Description

[Pierre Saslawsky]

Verified with current debug and optimized builds on the Mac:
- Configure your internet access for Modem or DSL
- Close your internet connection
- Launch Viewer
===> You get an alert from the Modem or DSL driver saying that there was an 
attempt to start TCP services while the connection is closed
- Open TCP Watcher or any utility program that can list the currently open TCP 
connections.
===> You can see 2 connections to self (127.0.0.1)

It may be fairly annoying to users who configure their machines to automatically 
connect to the internet on the first connection attempt: even if they just browse 
local files, the modem will dial-up.

This could be a more serious issue for Embedding: these machines are almost 
always to connect automatically.

[Darin Fisher]

There are two possible explanations for this:

1) PSM uses a local socket pair for communication.

2) nsSocketTransportService uses a local socket pair for interrupting the call
   to PR_Poll (in order to add/remove sockets to the set being polled).

cc'ing mac folks who may have further comments.

I'm actually going to pull the embed keyword as we're not driving hard on mac
embedding right now. When we are, this will get folded into the mac issue
embedding meta bug.

Comment 5

[gordon]

PSM and PollableEvents work this way on Windows and Linux as well, so if 
embedding has an issue with it on ANY platform, you may want to put the keyword 
back.

The only platform I know how to fix is the Macintosh (pre-Mac OS X) because we 
don't use native threads, so we have more places to hook in a solution.

Bugs targeted at mozilla1.0 without the mozilla1.0 keyword moved to mozilla1.0.1 
(you can query for this string to delete spam or retrieve the list of bugs I've
