* gen_funcs.sh: gkbuild(): Export $TMPDIRThomas Deutschmann2019-07-211-1/+2
| | | | | | | Some portage programs like eltpatch depend on $TMPDIR. Bug: https://bugs.gentoo.org/690264 Signed-off-by: Thomas Deutschmann <whissi@gentoo.org>
* gen_funcs.sh: gen_die(): Don't advertise $LOGFILE until ↵Thomas Deutschmann2019-07-211-3/+8
| | | | | | | | | determine_real_args() was called Before determine_real_args() was called, $LOGFILE will probably contain content from a previous run. Signed-off-by: Thomas Deutschmann <whissi@gentoo.org>
* gen_funcs.sh: dump_debugcache(): Echo DEBUGCACHE when $LOGFILE isn't writableThomas Deutschmann2019-07-211-1/+9

* Rework --ssh supportThomas Deutschmann2019-07-141-0/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - To enable sshd in initramfs user MUST now set "dosshd" kernel command-line parameter. - "gk.sshd.wait" kernel command-line parameter was added to interrupt boot process for X seconds to allow for remote login (can be used like an remote rescue shell). - For remote unlock of LUKS-encrypted root or swap device, user can still send unencrypted keyfile via SSH like $ cat ~/root.unencrypted.key | ssh root@<remote-host> -C post root or user can now just SSH into the remote host and call "unlock-luks" like remote rescueshell ~ # unlock-luks root to get a cryptsetup prompt. NOTE: When manually unlocking the encrypted LUKS device, user must call "resume-boot" afterwards to resume booting. - "--ssh-authorized-keys-file" parameter added which can be used to specify a different file than default "/etc/dropbear/authorized_keys" file. - "--ssh-host-keys" parameter added to control if in initramfs embedded sshd should create its own pair of hosts keys (which will be stored in "/etc/dropbear for re-use, default), use host keys from host system or should generate host keys at runtime on each boot. - "ip" kernel command-line parameter will now default to DHCP usage but does also support addr/CIDR notation to specify a static address. - "gk.net.iface" kernel command-line parameter was added to use a different interface than "eth0". You can either use an interface name or use a MAC address. - "gk.net.gw" kernel command-line parameter was added which will allow user to set specific gateway when DHCP isn't used. - "gk.net.routes" kernel command-line parameter was added which will allow user to set additional routes when DHCP isn't used. Please read manpage for additional parameters and more details. Signed-off-by: Thomas Deutschmann <whissi@gentoo.org>
* gen_funcs.sh: Refactor trap_cleanup()Thomas Deutschmann2019-07-141-0/+11

* Add genkernel worker module "unpack"Thomas Deutschmann2019-07-141-0/+51
| | | | | | This commit will add support for "unpack" task. Signed-off-by: Thomas Deutschmann <whissi@gentoo.org>
* Add genkernel worker module "gkbuild"Thomas Deutschmann2019-07-141-0/+217
| | | | | | | | | | | | | | In the future, genkernel will try to compile all programs used in genkernel's initramfs on its own instead of copying from host system. This commit will add support for gkbuilds. A "gkbuild" is like an ebuild but with reduced functionality. Using an ebuild-like system will make it easier to maintain those programs in a standardized way, especially with reworked cross-compile support. Signed-off-by: Thomas Deutschmann <whissi@gentoo.org>
* Add code for genkernel workerThomas Deutschmann2019-07-141-0/+1
| | | | | | | | | | | | In the future, genkernel will perform tasks such as compilation or unpack in a separated process, primarily to allow for sandbox usage, similar how portage executes ebuilds. Each task will have its own "worker" script. This commit will add the code required to run such a worker. Signed-off-by: Thomas Deutschmann <whissi@gentoo.org>
* Rework cross-compile supportThomas Deutschmann2019-07-141-1/+227
| | | | | | | | | | | | | - Add new "--cross-compile" parameter which will accept a target triplet and replaces "--arch-override", "--utils-arch", "--utils-cross-compile" and "--kernel-cross-compile" parameter. - Add "--utils-cflags" to allow user to overwrite CFLAGS used for compiling programs for initramfs. - Add tc-* functions.

* gen_funcs.sh: Store $IFS in $GK_DEFAULT_IFSThomas Deutschmann2019-07-141-0/+3
