new factotum/authsrv/keyfs

[cinap_lenrek@felloff.net]

i just pushed the new code which adds dp9ik authentication support.

to update a system, the following things need to be done:

# make sure you have the latest libmp/libsec 
cd /sys/src/libmp; mk install
cd /sys/src/libsec; mk install

# rebuild mpc (required for libauthsrv)
cd /sys/src/cmd; mk mpc.install

# rebuild libauthsrv / libauth
cd /sys/src/libauthsrv; mk install
cd /sys/src/libauth; mk install

# rebuild factotum/keyfs/authsrv
cd /sys/src/cmd/auth; mk install

# then rebuild kernel to include the new factotum,
# but dont reboot your authserver just yet...
cd /sys/src/9/pc; mk install

# if your /adm/keydb is still in DES format (cat it to see
# if the keyfile starts with the AES signature), you need to
# convert it to use the new dp9ik protocol:

# make backup
cp /adm/keys /adm/keys.old
auth/convkeys -ap /adm/keys

# now set the aes key in nvram (so authserver can decrypt
# the keydb when it boots)
auth/wrkey

# now you can reboot the AS and once its up, you have to
# set new passwords for the users. logging in with the
# old p9sk1 plan9 password should continue to work if
# you skip this.
passwd [username]

# if there are issues logging in with dp9ik because keydb
# doesnt have the new key yet, you can use delkey(1) to
# remove the dp9ik key from factotum as a work arround.
