2015-05-28Add resize2fs and ability to run resize2fs via GUIEthan Yonker1-1/+4
Note: Only works on ext2/3/4 partitions. Only tested on ext4. We can use this in some cases to resize the data partition if an incorrect fstab caused recovery to not reserve the 16KB for a crypto footer. Sometimes the BoardConfig for a custom ROM does not have the correct size for the system partition and if the ROM flashes a raw system image, that image will not take up the full block device. Running resize2fs can fix the size and may allow more room in the system partition for customizations like busybox or a larger gapps package. Sometimes flashing a factory image may flash userdata with an image with a file system that does not take up the full size of the block device (e.g. factory images for the Nexus 6 will flash userdata with a ~24GB userdata image, wasting ~30GB of space). Using resize2fs we can easily fix this issue without having to do a full format data. Change-Id: I631f5c6f567bbc6a9241e5dd95f1e435820a1b13
2015-05-27Mount system as read-only by defaultEthan Yonker1-0/+3
Mounting system as rw can prevent future OTA updates. The purpose of this patch set is to prevent TWRP from mounting sytem as rw on the first boot. Device maintainers should update their twrp.fstab files on these devices to include an additional line: /system_image emmc /dev/block/../system This line will allow TWRP to create a raw system image backup to ensure that the user can return to an original state for future OTA updates.

2015-02-02MTP: make MTP work even if unplugged and repluggedEthan Yonker1-0/+1
Set up a loop to keep trying to open / read the MTP device so that MTP will work even if the device is unplugged during boot or unplugged and replugged in. Change-Id: I0d3a3b7c91ce84a8cbed16caa4b15efee35b3641
2015-01-27Add cancel backup capability.bigbiff1-3/+8
This will stop the iteration of the partition objects, kill the current twrpTar thread and remove the backup directory. Implement TWAtomicInt class to give us a wrapper that automatically uses mutexes before the read and write to help ensure that the reads and writes will be atomic based on documentation.

2015-01-09Allow flashing of images via the GUIEthan Yonker1-2/+6

2014-12-19MTP add/remove storage instead of disabling MTPEthan Yonker1-0/+8
Implement a pipe between TWRP and MTP to allow TWRP to tell MTP to remove storage partitions as they become unavailable (e.g. during a wipe, unmount, etc) instead of disabling MTP completely. This includes some fixes and improvements in destructors to properly remove / delete various items. This also means that we will not be toggling adb off and on quite as often. I do not like that we had to add another thread, but we were unable to use select() on the mtp_usb character device because this device does not support polling. Select always returned indicating that the mtp file descriptor was ready to be read and the resulting read would block. The read block prevented us from being able to include reading of the pipe between TWRP and MTP in the main MTP thread. We might want to add a return pipe letting TWRP know if the removal of the storage device was successful, but I am not sure how we want to implement this. It would invovle timeouts in both TWRP and MTP to ensure that we returned a failure indicator in a timely manner to TWRP and prevent deleting the storage device in the case of a failure. Right now we make no attempt to ensure that an MTP operation is underway like a large file transfer, but we were not doing anything like this in the past. In some respects we have limited control over what happens. If the user installs a zip that unmounts a storage partition, we will not know about the change in storage status anyway. Regular Android does not have these troubles because partitions rarely get unmounted like in recovery. At some point, we have to hold the user accountable for performing actions that may remove a storage partition while they are using MTP anyway. Ideally we do not want to toggle the USB IDs and thus toggle adb off and on during early boot, but I am not sure what the best way to handle that at this time.

2014-12-04Reduce libs needed for decrypt and clean up old decypt filesEthan Yonker1-3/+2
Trim cryptfs.c to remove functions that TWRP does not use for decrypt and remove the need for libfs_mgr from cryptfs.c by passing some items to cryptfs.c from the partition manager. Add support for new fstab flags: encryptable and forceencrypt=/path/to/cryptokey For example: flags=forceencrypt=/dev/block/platform/sdhci-tegra.3/by-name/MD1 Note that "footer" is the default, so you do not need to set this flag on devices that use the footer for the crypto key. Also add mounttodecrypt if you need to mount a partition during the decrypt cycle for firmware of proprietary libs. Clean up decrypt and only support one version Android 5.0 lollipop decrypt should be backwards compatible with older versions so we will only support one version, 1.3 that came with 5.0 lollipop. Remove support for Samsung TouchWiz decrypt. It does not work with the latest versions of Samsung encryption anyway and it has not been updated to work with any AOSP decryption higher than 1.1 Change-Id: I2d9c6e31df50268c91ee642c2fa090f901d9d5c9

2014-04-16Support alternative .android_secure locationMatt Mower1-1/+2
Some devices (jewel, m8) have .android_secure at a non-standard location. Allow a different partition to be specified as the home of .android_secure using the fstab flag 'andsec'. Using the /data/media variant of jewel as an example, recovery.fstab or twrp.fstab could be edited like follows: /external_sd vfat /dev/block/mmcblk1p1 flags=display="MicroSD";andsec Note, this is NOT a method to move .android_secure in your ROM. Your ROM must already write to this alternative location. Change-Id: I3a6e4e63aaddb35870b79e80938b0f9c2c902443
