Subject: [PATCH] core:execute: fix fork() fail handling in exec_spawn()
|
|
|
40a46b |
|
|
|
40a46b |
If pid < 0 after fork(), 0 is always returned because r =
|
|
|
40a46b |
exec_context_load_environment() has exited successfully.
|
|
|
40a46b |
|
|
|
40a46b |
This will make the caller of exec_spawn() not able to handle
|
|
|
40a46b |
the fork() error case and make systemd abort assert() possibly.
