2019-03-28	Transfer /dev/mtp_usb fd ownership when instancing MtpDevHandle	dianlujitao	1	-1/+1
	/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
2019-03-20	MTP FFS updates:	bigbiff bigbiff	1	-556/+636
	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.

2015-02-02	MTP: make MTP work even if unplugged and replugged	Ethan Yonker	1	-6/+8
	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
2014-12-29	Improve MTPServer logging of read errors	Ethan Yonker	1	-4/+8
	Unless MTP debug logging is enabled, you will miss the error and will not know that something went wrong in the log. Change-Id: I51f4758b415eb38e808ec8b1c9788b505bf88c65

2014-12-19	MTP add/remove storage instead of disabling MTP	Ethan Yonker	1	-2/+27
	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.

2014-12-12	Attempt to set the proper uid/gid/contexts on new files and dirs	Ethan Yonker	1	-0/+3
	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

2014-09-04	MTP: Better handling of stat	Ethan Yonker	1	-1/+6
	Do some error checking of lstat calls and better handle those errors. Use lstat instead of dirent to check if an item is a directory because dirent does not return the correct item type when using exfat-fuse. Change-Id: I0d008aff55a0e0b4fbeae24cf8d0c04453b7b77e
