This is modeled after LXD's API extension checks. This allows API users to query the given LXC instance whether a given API extension is supported. Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com>

# API extensions
|
|
|
|
The changes below were introduced to the LXC API after the 3.0 API was finalized.
|
|
|
|
They are all backward compatible and can be detected by client tools by
|
|
called the `lxc_has_api_extension` function.
|
|
|
|
## lxc\_log
|
|
|
|
This introduces a way to initialize a logging instance from the API for a given
|
|
container.
|
|
|
|
## lxc\_config\_item\_is\_supported
|
|
|
|
This introduces the `lxc_config_item_is_supported` function. It allows users to
|
|
check whether their LXC instance supports a given configuration key.
|
|
|
|
## console\_log
|
|
|
|
This adds support to container's console log. The console log is implemented as
|
|
an efficient ringbuffer.
|
|
|
|
## reboot2
|
|
|
|
This adds `reboot2()` as a new API extension. This function properly waits
|
|
until a reboot succeeded. It takes a timeout argument. When set to `> 0`
|
|
`reboot2()` will block until the timeout is reached, if timeout is set to zero
|
|
`reboot2()` will not block, if set to -1 `reboot2()` will block indefinitly.
|
|
|
|
## mount\_injection
|
|
|
|
This adds support for injecting and removing mounts into/from a running
|
|
containers. Two new API functions `mount()` and `umount()` are added. They
|
|
mirror the current mount and umount API of the kernel.
