* firmware: copy only the necessary firmware(s) into initramfsDmitry Baranov2023-08-301-33/+58
| | | | | | | | | | | | | | | | | | | FIRMWARE=yes behavior is changed: Only the minimum number of firmware files will be copied. The list is generated using the `modinfo -F firmware [modules]...` command. The ability to copy all firmware(s) is also available with a new ALLFIRMWARE setting (see the modified genkernel.conf for more details). As for changes in the source code: gen_moddeps.sh: Significantly redesigned module list generation. To get a list of modules, use the `mod_dep_list()` function instead of `gen_dep_list()`. Modules that are not in the kernel (=n or invalid) will be filtered out. Aliases will be replaced with real names (including dependencies).

* genkernel: add keyctl support for loading LUKS passphrase into a keyringMaciej S. Szmigiero2022-05-221-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cryptsetup LUKS2 format comes with an ability to automatically unlock multiple devices (root, swap, etc.) sharing the same passphrase, without retyping it for each of them, by loading it into the user keyring. This commit adds such (optional) genkernel support for loading LUKS passphrase into the user keyring on boot. In the default mode of operation the newly added key is (possibly) used only to unlock root and swap devices and is removed soon after that. By providing appropriate kernel command line parameter the key can be left in the keyring instead (with an optional timeout) for unlocking other LUKS devices post-initramfs time. Because one of the most common use cases of this functionality will be having an encrypted swap for doing suspend to disk (hibernation) let's also make sure that we don't unlock the root device when doing so is unnecessary (when we are resuming the system from hibernation). Since the security of a FDE passphrase is of paramount importance in this solution significant care has been taken not to leak it accidentally: * The passphrase is read directly by keyctl to avoid storing it in the shell, * If the passphrase is used only to unlock root and swap devices (which is the default mode of operation) the init script will check whether its removal from keyring has actually succeeded and, if not, reboot the system rather than continue while leaving it exposed, * keyutils includes a patch (already upstreamed) to wipe the passphrase from memory when no longer needed.

* Refactor (compressed) kernel module handlingThomas Deutschmann2021-09-091-1/+21
| | | | | | | | | | | | | | | | | | | | | | To support a specific module compression algorithm, two things are needed: Used depmod utility on host system building the kernel must support chosen module compression algorithm to generate proper modules.dep file or genkernel would be unable to read module dependencies when copying modules to initramfs. At runtime, used modprobe utility must be able to handle chosen module compression algorithm or modules would be unloadable. To address the first requirement, genkernel will now check if used kmod utility on host system supports chosen module compression algorithm. To address the runtime requirement, this commit will switch from BusyBox's modutils implementation to kmod because BusyBox does not support ZSTD compression (yet).
