Hello,
I upgraded my signing server to Debian 13, but I have a problem with my HSM :
Oct 15 21:09:18 arrakeen knotd[29552]: error: [durel.org.] zone event 'load'
failed (PKCS #11 token not available)
Oct 15 21:09:18 arrakeen knotd[29552]: error: [geekwu.org.] zone event 'load'
failed (PKCS #11 token not available)
keymgr gives me the same error :
# keymgr geekwu.org list
error: failed to initialize KASP (PKCS #11 token not available)
despite hsmwiz being able to access the key :
# hsmwiz identify

Knot is using this keystore :
keystore:
- id: nitrokey
backend: pkcs11
config: "pkcs11:pin-value=*** /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so"
I verified /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so still exists, and ldd doesn't
report any missing dependency
strace let me see communication with pcscd, whose logs have these :
Oct 15 21:20:14 arrakeen systemd[1]: Started pcscd.service - PC/SC Smart Card Daemon.
Oct 15 21:20:20 arrakeen pcscd[33186]: 00000000 ../src/auth.c:166:IsClientAuthorized()
Process 33204 (user: 134) is NOT authorized for action: access_pcsc
Oct 15 21:20:20 arrakeen pcscd[33186]: 00000071 ../src/winscard_svc.c:357:ContextThread()
Rejected unauthorized PC/SC client
After a bit of digging, I found it's controlled by polkit, and added a brutal rule :
cat /etc/polkit-1/rules.d/pcsc.rules
/* -*- mode: js; js-indent-level: 4; indent-tabs-mode: nil -*- */
polkit.addRule(function(action, subject) { if (subject.isInGroup("pcsc")) {
return polkit.Result.YES; } })
with knot added to the pcsc group, it can access the HSM again.
Do you know of a better way to configure ?
NB: I'm using another account, as I began to write this with no DNS server running
