I do run a hardened stable Gentoo Linux server w/ kernel 4.7.3-ahrdened-r1
where I use an ext4fs directory /var/lib/tor in the following way :
scp ~/.cryptoSalt user@host:/tmp
cat /tmp/.cryptoPass | ssh user@host 'sudo -u tor e4crypt add_key -S
$(cat /tmp/.cryptoSalt) /var/lib/tor && sudo /etc/init.d/tor start; rm
/tmp/.cryptoSalt'
Works fine after reboot.
But after 4 days or so a restart of the service "tor" fails with messages like :
Sep 14 11:27:10.000 [warn] Could not open
"/var/lib/tor/data/keys/secret_id_key": Required key not available
Sep 14 11:27:10.000 [warn] Error reading private key from
"/var/lib/tor/data/keys/secret_id_key"
Sep 14 11:27:10.000 [err] Error loading private key.
Sep 14 11:27:10.000 [err] Error initializing keys; exiting
Sep 14 11:27:10.000 [warn] Couldn't open "/var/lib/tor/data/state.tmp"
(/var/lib/tor/data/state) for writing: Required key not available
Sep 14 11:27:10.000 [warn] Unable to write state to file
"/var/lib/tor/data/state"; will try again later
No way to get it repaired other than rebooting the machine.
Any hints ?
