lib: Add AUTH_MSG_DECRYPT Extend the auth_message struct to support the AUTH_MSG_DECRYPT operation, allowing the existing authentications methods to be used for passing a disk password from the UI to pb-discover. In addition add DEVICE_TYPE_LUKS to identify encrypted disk devices. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
ui/ncurses: Keep track of the default boot option Keep track of the default boot option, and prefix its display name with a '(*)' to point it out to the user. This avoids having to authenticate with pb-discover even if only booting the default option. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
lib/pb-protocol: Add PB_PROTOCOL_ACTION_AUTHENTICATE Add a new "authenticate" action. Depending on the 'op' field this is either a) an authentication request, b) a response indicating the result, or c) a request to change the password. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
ui/ncurses: Reset console options on boot The ncurses UI sets a few console options at startup that are needed for ncurses to work properly. These aren't reset however and can lead to quirks like the cursor being invisible after kexecing to the next kernel. The UI process doesn't have time to reset these when it is killed by kexec, so instead add a 'boot_active' field to status updates. This is set by boot.c's update handler so the UI can assume it is about to boot if it receives a status update with this field, and resets the console options. If the boot is cancelled for any reason the status update will reflect that and the console options are restored. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
lib: Add support and helpers for IPv6 host addresses Recognise IPv6 addresses and URLs, and allow an interface_info struct to have both an IPv4 and IPv6 address. The addr_scheme() helper returns the address family of a given address. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
protocol: Add definition and serialisation for temporary autoboot Add a new message format for a temporarily-applied autoboot setting. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
discover: Handle plugin install request Handle "_PLUGIN_INSTALL" requests from clients. Calling the pb-plugin script from pb-discover ensures different clients don't trip over each other. Successfully installed plugins are automatically communicated back to clients once pb-plugin sends a 'plugin' user event. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
discover/pxe-parser: Recognise plugin sources Extend the pxe-parser to recognise 'PLUGIN' as well as the usual 'LABEL' when parsing a config file. 'PLUGIN' will be used to specify an option that provides the location of an installable pb-plugin file, named by the 'TARBALL' label. Since plugin options are discovered via the same mechanism as boot options treat them the same as boot options and at the 'type' field to the boot_option struct to differentiate between them.

lib: Add plugin_option type and protocol Add a new struct 'plugin_option' to represent pb-plugins that are installed on the system. This consists of plugin metadata and an array of installed executables. This also adds two new pb-protocol actions to advertise the addition of a new plugin_option, and to remove known plugin_options. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
discover: Maintain a backlog of status updates Add status updates to a persistent list in the discover_server struct, and send each client the backlog on connect. This avoids clients missing useful messages from early init. Clients will only show this in the backlog screen to avoid flooding the client's status line.

types: shorten boot_status definitions struct boot_status is a bit misnamed; we report status on things that aren't just the boot status (eg, discovery). This change refactors struct boot_status into just struct status. We give the type enum a name, and shorten the enum values to suit.

Support HTTP(S) proxies when downloading resources Allow the user to specify a HTTP and HTTPS proxy server. The discover server will set the http_proxy and https_proxy environment variables, enabling the proxy servers for any further HTTP(S) requests.

Consolidate petitboot,tty and petitboot,console Commit ce54f86 "Add petitboot,tty and track available consoles" added the petitboot,tty parameter, but the petitboot,console parameter is also recognised by Petitboot. These are ultimately handled by the 30-add-offb and 80-set-stdout hooks respectively, but exist for mostly the same purpose. We consolidate these down to just the original petitboot,console parameter. If the contents of petitboot,console have been configured by Petitboot (ie. it is of the form /dev/dev# [ Description ]) we behave as normal, otherwise we assume that petitboot,console contains a full OF path to the intended console device and do not allow it to be modified. This follows petitboot,console's original intent to be a debug aid, and takes precedence over any other use. The 80-set-stdout hook is removed as 30-add-offb now accounts for both use cases.

discover: Avoid writing network overrides to NVRAM Explicitly keep track of whether the current interface config was set by an IPMI network override, and avoid overwriting any saved config unless the override was marked persistent. Signed-off-by: Samuel Mendoza-Jonas <sam@mendozajonas.com>
