2017-04-03Boot control HAL based on the A/B headers.Alex Deymo2-0/+12
The added bootctrl.bcb module implement the legacy interface for the bootctrl HAL based on the Boot Control Block (BCB) and the headers already specified in the booloader_message library. This serves as a reference implementation of the boot_control HAL. Bug: 32707546 Test: Tested internally that a device can use this HAL to flip slots and recovery from a /misc wipe.

2017-03-25libbootloader_message: use different fstab paths for normal/recovery bootBowgo Tsai1-2/+8
libbootloader_message is used by both normal boot and recovery boot. It needs to use different fstab paths, respectively. Otherwise, factory reset will fail when we move /fstab.{ro.hardware} to /vendor/etc/. Recovery boot: fs_mgr_read_fstab_with_dt("/etc/recovery.fstab") Normal boot: fs_mgr_read_fstab_default() Bug: 35811655 Bug: 36502022 Test: normal boot sailfish, go to Settings > System & tap on "Factory Data reset" Test: recovery boot sailfish Change-Id: I253f5bdfb9be8a01f80856eb1194f85cdf992bbd
2017-03-10recovery: replacing fs_mgr_read_fstab() with new fs_mgr APIsBowgo Tsai1-18/+5
The fstab settings of early-mounted partitions (e.g., /vendor) will be in kernel device tree. Switch to the new API to get the whole settings with those in device tree: fs_mgr_read_fstab_with_dt("/etc/recovery.fstab") The original default /fstab.{ro.hardware} might be moved to /vendor/etc/. or /odm/etc/. Use another new API to get the default fstab instead of using the hard-coded /fstab.{ro.hardware}. This API also includes the settings from device tree: fs_mgr_read_fstab_default() Bug: 35811655 Test: boot sailfish recovery Change-Id: Iaa56ac7f7b4c4dfc7180c65f03e9a37b94f1de09
2017-02-16Fix bldr msg file open mode when offset specifiedMatt Mower1-4/+1
It was pointed out to me by gmrt that O_APPEND is incorrect, as lseek before writing would be undone (perhaps we avoided this issue due to an inability to write beyond the end of a partition) and O_RDWR is not necessary to lseek. When AOSP switched from fopen to open, they also removed the full partition wipe (fopen in wb mode) before each write, so this is no longer an issue. Completely restore the original AOSP file access mode flags. Change-Id: I42b4efc5f499360ce5b761d3a2a5d4dac4cdfb65
2017-02-02Allow custom bootloader msg offset in block miscMatt Mower2-1/+9
Globally define BOARD_RECOVERY_BLDRMSG_OFFSET with a decimal integer to offset the read/write location in misc where the bootloader message should appear. Example: BOARD_GLOBAL_CFLAGS := -DBOARD_RECOVERY_BLDRMSG_OFFSET=2048 Edify commands get_stage and set_stage need to be aware of the custom bootloader msg offset because they write the stage directly to the BCB.

2017-01-11bootloader_message: Allow TWRP to ignore wipe-data command into miscnailyk-fr2-0/+15
* Rebase of https://gerrit.omnirom.org/#/c/20750/ patch-set 3 * Original commit message: fix: recently a change in AOSP causes a bootloop to TWRP (and therefore all ROM's based on it) Reason: AOSP enables use of /misc partition and normally the fstab in TWRP will not have /misc added. The problem is now when Android writes a wipe command to /misc it will force TWRP to boot but TWRP will do nothing - leaving the cmd in /misc. This results in a bootloop to TWRP. Solution: I added a new var TW_IGNORE_MISC_WIPE_DATA which can be set to "true" in Boardconfig.mk of a device requiring this which then ignores /misc commands like it would be when /misc would be just not in fstab BUT with this change TWRP clears the bit in /misc so a normal boot can happen. Besides that if the device do not have an own recovery key combo and /misc is enabled we want to open TWRP after walking through the factory reset screen - without actually doing a factory reset. kudos to nailyk (and DevUt) for the help with the C++ code!

2016-12-15Add update_bootloader_message() to fix two-step OTAs.Tao Bao2-1/+27
This is a retry of commit 7e31f421a514da09b90e46dbd642a5e9b16e0003. Commit bd56f1590c967205dc45eb2ec298aa8d2aacb740 switches to calling write_bootloader_message(<options>) in get_args(), which unintentionally resets the stage field thus breaks two-step OTAs. This CL adds update_bootloader_message(<options>), which only sets the command field (to "boot-recovery") and the recovery field (with the specified options). Bug: 33534933 Test: Apply a two-step package. Test: recovery_component_test passes. Change-Id: Ie0b1ed4053d2d3c97d9cb84310d616b28fcfc72e
