題目: [exim-dev] gnutls / exim : gnome-keyring:: couldn't connect to:
/home/ametzler/.cache/keyring-vZ6lZn/pkcs11: Permission denied
Hello,
After the the GnuTLS revamp it loooks like PKCS#11 modules are
suddenly (unnecessarily) autoloaded and fail due to SUID:
ametzler@argenau:~$ mailq
ametzler@argenau:~$ gnome-keyring-daemon --start --components=pkcs11
GNOME_KEYRING_CONTROL=/home/ametzler/.cache/keyring-Blme9u
GNOME_KEYRING_PID=1274
ametzler@argenau:~$ export GNOME_KEYRING_CONTROL=/home/ametzler/.cache/keyring-Blme9u GNOME_KEYRING_PID=1274
ametzler@argenau:~$ mailq
WARNING: gnome-keyring:: couldn't connect to: /home/ametzler/.cache/keyring-Blme9u/pkcs11: Permission denied
ametzler@argenau:~$
The same behavior can also be reproduced with a SUID gnutls-cli[1].
Any idea on how to properly fix this?
