[Bug] Not enough permissions for /iana.d/ if default configuration is used #56

Closed kernbug closed 7 months ago

kernbug commented 7 months ago

Describe the bug Hello. Thank you for the image re-work :)

Permission issue with iana.d with default example here: https://github.com/madnuttah/unbound-docker/blob/main/doc/DETAILS.md

Feb 19 14:07:57 unbound[1:0] notice: init module 0: validator
Feb 19 14:07:57 unbound[1:0] notice: init module 1: iterator
Feb 19 14:07:57 unbound[1:0] info: start of service (unbound 1.19.1).
Feb 19 14:07:59 unbound[1:0] error: could not open /iana.d/root.zone.tmp1: No such file or directory

To Reproduce

docker run --name madnuttah-unbound -d \
--user 1000 \
-e UID=1000 \
-e GID=1000 \
-p 5335:5335/udp \
-p 5335:5335/tcp \
--restart=unless-stopped \
madnuttah/unbound:latest

Expected behavior No errors with rootless container having only user permissions inside container.

A pleasure. Thanks for your heads-up, it was about time to rework all the things.

I'm just wondering about the path shown, there's still a incorret path in the config. I'll fix that.

Would you please verify it's running with this unbound.conf?

# DNSCrypt
# To enable, use --enable-dnscrypt to configure before compiling.
# Caveats:
# 1. the keys/certs cannot be produced by Unbound. You can use dnscrypt-wrapper
#   for this: https://github.com/cofyc/dnscrypt-wrapper/blob/master/README.md#usage
# 2. dnscrypt channel attaches to an interface. you MUST set interfaces to
#   listen on `dnscrypt-port` with the follo0wing snippet:
# server:
#     interface: 0.0.0.0@443
#     interface: ::0@443
#
# Finally, `dnscrypt` config has its own section.
# dnscrypt:
#     dnscrypt-enable: yes
#     dnscrypt-port: 443
#     dnscrypt-provider: 2.dnscrypt-cert.example.com.

#     dnscrypt-provider-cert: /path/unbound-conf/keys2/1.cert

# CacheDB
# External backend DB as auxiliary cache.
# To enable, use --enable-cachedb to configure before compiling.
# Specify the backend name
# (default is "testframe", which has no use other than for debugging and
# testing) and backend-specific options.  The 'cachedb' module must be
# included in module-config, just before the iterator module.
# cachedb:
#     backend: "testframe"
#     # secret seed string to calculate hashed keys
#     secret-seed: "default"

#     # redis server's TCP port
#     redis-server-port: 6379
#     # if the server uses a unix socket, set its path, or "" when not used.
#     # redis-server-path: "/var/lib/redis/redis-server.sock"
#     # if the server uses an AUTH password, specify here, or "" when not used.

# IPSet
# Add specify domain into set via ipset.

# Dnstap logging support, if compiled in by using --enable-dnstap to configure.

# Response Policy Zones
# RPZ policies. Applied in order of configuration. QNAME, Response IP
# Address, nsdname, nsip and clientip triggers are supported. Supported
# actions are: NXDOMAIN, NODATA, PASSTHRU, DROP, Local Data, tcp-only
# and drop.  Policies can be loaded from a file, or using zone
# transfer, or using HTTP. The respip module needs to be added
# to the module-config, e.g.: module-config: "respip validator iterator".
# rpz:
#     name: "rpz.example.com"
#     zonefile: "rpz.example.com"

If it works for you, I'd be happy to see a PR of yours.

Thank you @kernbug.

This config works and will be fixed. Thanks.
