LoveSy	af01a36296	Refactor magic mount to support overlayfs ... Previously, magic mount creates its own mirror devices and mount mirror mount points. With these mirror mount points, magic mount can get the original files and directory trees. However, some devices use overlayfs to modify some mount points, and thus after magic mount, the overlayed files are missing because the mirror mount points do not contain the overlayed files. To address this issue and make magic mount more compatible, this patch refactors how magic mount works. The new workflows are as follows: 1. make MAGISKTMP a private mount point so that we can create the private mount points there 2. for mirror mount points, we instead of creating our own mirror devices and mount the mirror mount points, we "copy" the original mount points by recursively mounting / 3. to prevent magic mount affecting the mirror mount points, we recursively set the mirror mount points private 4. to trace the mount points we created for reverting mounts, we again make the mirror mount points shared, and by this way we create a new peer group for each mirror mount points 5. as for tracing the newly created tmpfs mount point by magic mount, we create a dedicated tmpfs mount point for them, namely worker mount point, and obviously, it is shared as in a newly created peer group for tracing 6. when reverting mount points by magic mount, we can then trace the peer group id and unmount the mount points whose peer group ids are created by us The advantages are as follows: 1. it is more compatible, (e.g., with overlayfs, fix #2359) 2. it can mount more partitions for which previous implementation cannot create mirror mount points (fix #3338)	2023-02-25 18:19:46 -08:00

GaryOderNichts	e3c8d723e3	Add linebrake notice for module.prop ... This made some trouble when creating a module.prop on Windows. The file could not be read properly by magisk manager and my module folder had an \r at the end which made it unremovable through Magisk Manager.	2020-03-12 00:34:56 -07:00
