Hello,

as announced on freebsd-hackers a few days ago, I ported the
rfilter/wfilter features of NetBSD's mount_portal to 4.7-p2.
Because the port was very trivial and rfilter/wfilter worked
well on 4.7-p2, I tried to merge the code in 5.0-RC2 mount_portalfs
and discovered, that mount_portalfs did not work. First I thought
this is a problem with the rfilter/wfilter code, but also the original
mount_portalfs has this problem.

Description:

my portal.conf:
tcp/           tcp tcp/
tcplisten/     tcplisten tcplisten/
fs/            file fs/

1.)

After mounting the portalfs,

# cat /p/tcp/www.jawa.at/21
220 ftp.jawa.at FTP server (ftpd) ready.
^C

portalfs hangs, and cat did not return on ^C or ^Z

2.)

After mounting the portalfs,

# cat /p/tcp

or

# cat /p/telnet

or

# cat /p/http

portalfs hangs instead of expected "cat: /p/telnet: No such file or directory"

Impact:

- umount /p does not work
- Further access to /p is not possible (e.x. ls)
- FreeBSD could not unmount all file systems on reboot,
  so fsck has to run on next boot.
