After upgrade to 2.45.1, git daemon has stopped working as expected. Upon clone, git-daemon logs the following: [1482] Connection from ::1:45090 [1482] Extended attribute "host": localhost [1482] Extended attribute "protocol": version=2 [1482] Request upload-pack for '/test.git' fatal: detected dubious ownership in repository at '/var/lib/git/test.git' To add an exception for this directory, call: git config --global --add safe.directory /var/lib/git/test.git Reproducible: Always Steps to Reproduce: 1. Create repository under /var/lib/git/test.git 2. Ensure git.socket systemd unit is started 3. Run git clone git://localhost/test.git Actual Results: git server refuses to read /var/lib/git/test.git because it detects dubious ownership git client reports fatal: Could not read from remote repository. Expected Results: git clone happens as usual I run my own git daemon systemd unit which doesn't use socket activation, which runs as a git user. This makes it work repositories owned by the git user, but not for repos owned by local users. My testing for this bug report is done with the git.socket unit on a fresh VM however. This also reproduces over HTTP via Apache with the following VirtualHost config: SetEnv GIT_PROJECT_ROOT /var/lib/git SetEnv GIT_HTTP_EXPORT_ALL ScriptAlias / /usr/libexec/git-core/git-http-backend/ <Directory "/usr/libexec/git-core"> <Files "git-http-backend"> Options +ExecCGI Require all granted </Files> </Directory>
Thanks for the report. This failure is caused by security fixes in 2.45.1 and friends releases, which set strict policies for cloning local repositories not owned by git user.
