Subject: [PATCH] systemctl: explicitly cast the constants to uint64_t
|
|
|
|
Otherwise under certain conditions `va_arg()` might get garbage instead
|
|
of the expected value, i.e.:
|
|
|
|
$ sudo build-o0/systemctl disable asdfasfaf
|
|
sd_bus_message_appendv: Got uint64_t: 0
|
|
Failed to disable unit: Unit file asdfasfaf.service does not exist.
