Hi, This one would be committed once new sys-apps/portage release is wrapped up and hits ~arch.
--- Title: Portage rsync tree verification Author: Michał Górny <mgo...@gentoo.org> Posted: 2018-01-xx Revision: 1 News-Item-Format: 2.0 Display-If-Installed: <sys-apps/portage-2.3.21 Starting with sys-apps/portage-2.3.22, Portage enables strong cryptographic verification of the Gentoo rsync tree by default. This aims to prevent malicious third parties from altering the contents of the ebuild repository received by our users. The verification is implemented using app-portage/gemato. Currently, the whole repository is verified after syncing. On systems with slow hard drives, this could take around 2 minutes. If you wish to disable it, you can disable the 'rsync-verify' flag on sys-apps/portage or set 'sync-rsync-verify-metamanifest = no' in your repos.conf. Please note that the verification currently does not prevent Portage from using the repository after syncing. If 'emerge --sync' fails, do not install any packages and retry syncing. In case of prolonged or frequent verification failures, please make sure to report a bug including the failing mirror addresses (found in emerge.log). The verification uses keys provided by the app-crypt/gentoo-keys package. The keys are refreshed from the keyserver before every use in order to check for revocation. The post-sync verification ensures that the key package is verified itself. However, manual verification is required before the first use. On new Gentoo installations including portage-2.3.22, the verification of the keys will be covered by verifying the installation media and repository snapshot signatures. On existing installations, you need to manually compare the primary key fingerprint (reported by gemato on every sync) against the official Gentoo keys . An example gemato output is: INFO:root:Valid OpenPGP signature found: INFO:root:- primary key: 1234567890ABCDEF1234567890ABCDEF12345678 INFO:root:- subkey: FEDCBA0987654321FEDCBA0987654321FEDCBA09 The primary key printed must match 'Gentoo Portage Snapshot Signing Key' on the site. Please make sure to also check the certificate used for the secure connection to the site! :https://www.gentoo.org/downloads/signatures/ --- -- Best regards, Michał Górny
