+From: Simon Peter <dn.tlp@gmx.net>
+Subject: Bug#306261: pppd does not properly close /dev/ppp on persist
+
+When using the kernel PPPoE driver, pppd never
+closes /dev/ppp when the link has come down.
+
+It opens superfluous fds to the device each time it re-opens the
+connection, with the unclosed ones falsely reported always ready for
+data by select().
+
+This makes pppd eat up 100% CPU time after the first persist because of
+the always instantly returning select() on the unclosed fds.
+
+The problem also occurs with the upstream version, but does not occur
+when a pty/tty device is used for the ppp connection.

+Subject: Bug#284382: ppp: linkpidfile is not created upon detachment
+From: <herbert@gondor.apana.org.au>
+
+Package: ppp
+Version: 2.4.2+20040428-2
+Severity: wishlist
+
+When pppd detaches from the parent normally, that is, without nodetach
+or updetach set, the linkpidfile is not created even when linkname is
+set.
+
+This is because the create_linkpidfile call in detach() is only made
+if the linkpidfile is filled in.  However, linkpidfile is never filled
+in until create_linkpidfile has been called.
+
+IMHO the call should be made uncondtionally in detach() since
+create_linkpidfile does its own check on linkname anyway.
+
+Please note that the version of pppd in woody always wrote the
+linkpidfile after detaching.  It did so in main() however.  That
+call has now been removed which is why I'm seeing this problem.
+
