Subject: pppoe handles MOD_DEC_USE_COUNT incorrectly
Date: Sun, 11 May 2003 22:27:28 +0200 [thread overview]
Message-ID: <20030511202728.GA9018@suse.de> (raw)
Hi,
it seems pppoe does increase its usage count with each reconnect, but it
never releases it when the ppp connection dies.

I tried to fix it myself, but its not obvious to me where to place the
MOD_DEC_USE_COUNT. I believe the socket is still active when the
connection terminates, and pppoe_sock_destruct() is not called.
