safe.directory

fatal: detected dubious ownership in repository at

fatal: unsafe repository ('/builds/rPrca3qv/0/group/project' is owned by someone else)
To add an exception for this directory, call:
	git config --global --add safe.directory /builds/rPrca3qv/0/group/project

Fix in Poky: bitbake.conf: mark all directories as safe for git to read

This variable can be added to local.conf, but it invalidates whole sstate. Simple solution is to fix one recipe:

do_compile_prepend() {
    git config --global --add safe.directory ${S}
}

git config --global --add safe.directory ${CI_PROJECT_DIR}
 
# and if needed, for some submodules
git config --global --add safe.directory ${CI_PROJECT_DIR}/bootloader

Workarounds:

• Configure project clone directory as safe by default
• Mark project working directory as safe for Git

Best workaround: https://gitlab.com/gitlab-org/gitlab-runner/-/issues/29022#note_1356788508

config.toml

[[runners]]
  environment = ["GIT_CONFIG_COUNT=1", "GIT_CONFIG_KEY_0=safe.directory", "GIT_CONFIG_VALUE_0=*", "GIT_CONFIG_PARAMETERS='safe.directory=*'"]

or re-register runner with args:

gitlab-runner register \
      --env "GIT_CONFIG_COUNT=1" \
      --env "GIT_CONFIG_KEY_0=safe.directory" \
      --env "GIT_CONFIG_VALUE_0=*" \
      --env "GIT_CONFIG_PARAMETERS="'safe.directory=*'"

Note: According to bitbake.conf: mark all directories as safe for git to read :

This can be set globally via the
internal environment variable GIT_CONFIG_PARAMETERS, we can't use
GIT_CONFIG_*_KEY/VALUE as that isn't present in all the releases which
have the ownership check.
