* Transfer /dev/mtp_usb fd ownership when instancing MtpDevHandledianlujitao2019-03-283-4/+5
| | | | | | | | /dev/mtp_usb was opened before instancing MtpDevHandle, the existing fd should be passed in otherwise MtpDevHandle::start would be blocked as it attempted to open the device twice. Change-Id: I6afc5b6926930dad77aceac2f6a00e1c6759a883
* MTP FFS updates:bigbiff bigbiff2019-03-20111-1107/+13161
| | | | | | | | | | | | | | | | | This update splits old MTP code and new MTP code from Google into two trees, legacy and ffs. Depending on the SDK level, the build system will select the correct version. The reason for separating the versions out are due to older android trees not supporting the updated MTP code from Google. Most MTP code is from Google, with additions needed from implementing the Java functions in C++ for TWRP and FFS. We assume if you are in android-9.0 or above, your kernel has support for FFS over MTP. Verify that your init.rc is mounting the MTP FFS driver to the proper location.

* Decrypt FBE on 9.0 (backwards compatible)Ethan Yonker2018-08-311-1/+1
| | | | | | | | | | Building in 9.0 may require you to add a flag to your twrp fstab with the fileencryption details like: fileencryption=ice:aes-256-heh Verify this against your device's stock fstab of course. Change-Id: If9286f5d5787280814daca9fbc8f5191ff26a839
* Support v2 fstab formatEthan Yonker2017-11-282-3/+3
| | | | | | | | | | | | | | | | | | | | | | Auto detect and support both the v1 and v2 fstab formats Support putting TWRP style flags in a separate /etc/twrp.flags file twrp.flags format is the same as twrp.fstab (v1 with TWRP flags) Support using a wildcard in a block device and find all partitions: /usb-otg vfat /dev/block/sda* Support using sysfs entries (voldmanaged) and read uevents and scan for wildcard partitions from uevent data. (twvold?) May not be complete for some of the newer flags found in fstabs in newer build trees and there is a slim chance of a crash if the user removes a removable device while TWRP is performing actions. May need to add some kind of mutex to prevent the 2 threads from causing this crash. We need to start somewhere though and this change is pretty innocuous when not using a v2 fstab.

* Merge up to AOSP marshmallow-releaseEthan Yonker2015-10-091-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to maintain compatibility with older trees, we now have minadbd.old and minui.old. I had to use a TARGET_GLOBAL_CFLAG to handle ifdef issues in minui/minui.d because healthd includes minui/minui.h and there was no other alternative to make minui.h compatible with older trees without having to modify healthd rules which is outside of TWRP. Note that the new minui does not currently have support for qcom overlay graphics. Support for this graphics mode will likely be added in a later patch set. If you are building in a 6.0 tree and have a device that needs qcom overlay graphics, be warned, as off mode charging may not work properly. A dead battery in this case could potentially brick your device if it is unable to charge as healthd handles charging duties. Update rules for building toolbox and add rules for making toybox Use permissive.sh in init.rc which will follow symlinks so we do not have to worry about what binary is supplying the setenforce functionality (toolbox, toybox, or busybox). Fix a few warnings in the main recovery binary source code. Fix a few includes that were missing that prevented compiling in 6.0 Change-Id: Ia67aa2107d260883da5e365475a19bea538e8b97

* Move sleep during MTP startup to MTP threadEthan Yonker2014-12-291-0/+5
| | | | | | | | | | Some devices are very slow to respond to the sysfs requests. To prevent delaying the main GUI from booting during TWRP startup, we move the sleep delay to just before we open the MTP device and into the MTP thread so that it does not hold up the main TWRP thread.

* MTP add/remove storage instead of disabling MTPEthan Yonker2014-12-1913-17/+248
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Attempt to set the proper uid/gid/contexts on new files and dirsEthan Yonker2014-12-122-2/+5
| | | | | | | | | | Files and folders that we create during backups, copy log, or MTP operations often do not have the proper uid/gid/contexts assigned. We will attempt to read the proper contexts from the settings storage path and assign those same contexts to any files or dirs that we create. Change-Id: I769f9479854122b49b499de2175e6e2d026f8afd

* TWRP MTP: make sure inotify_fd is setEthan Yonker2014-11-251-9/+14
| | | | | | | | | | | Originally the inotify_init() call was part of a separate thread which would occasionally allow the readDirs function to run and start trying to add watches before inotify_fd was init'ed properly and result in the add watch failing. This patch set relocates the inotify_init call to happen outside and before starting the separate thread to ensure that inotify_fd is set properly.
