3e18f2bf40 roots: Fix an issue with volume_for_path().
The earlier commit in 2dfc1a3898
unintentionally changed the behavior. It gives a different result when
looking up non-existent mount points (e.g. /cache on marlin).

The logic behind volume_for_path("/xyz") is unclear:
- It's fine to return non-null value if it's called by
  ensure_path_mounted() before accessing that file "/xyz". (Just based
  on the function name, we're not actually having this case.)
- It should return nullptr if the caller is interested in the existence
  of that particular mount point "/xyz".

This CL renames the function to volume_for_mount_point(), which does an
exact match by querying the given mount point from libfs_mgr. The former
volume_for_path() has been moved down to function scope for serving
ensure_path_mounted() only.

Test: Build and boot into recovery on bullhead and marlin respectively.
      'View recovery logs'.
Test: 'Mount /system'
Test: 'Apply update from ADB'

846f307c6f Merge "Integer overflow observed while formatting volume" 2017-09-29 05:09:23 +00:00

2dfc1a3898 roots: volume_for_path() parses and tries prefixes.
Commit cc323958f99e40fea06c511656c69c0b2e2d47f7 in system/core has
changed fs_mgr_get_entry_for_mount_point() to do an exact match only,
which breaks the behavior in volume_for_path().

This CL changes the volume_for_path() implementation to parse and pass
prefixes locally. For a given path like "/cache/recovery/last_log", it
will in turn attempt the prefixes of "/cache/recovery/last_log",
"/cache/recovery", "/cache", "/" and return the first hit.

4fec8e9e9a Integer overflow observed while formatting volume
While calculating volume size, get_block_device_size() returns
u64 value but the returned value is assigned in ssize_t variable.
This may cause integer overflow if the volume size is beyond
ssize_t limit.

Use int64_t instead of ssize_t in get_file_size() and explicitly check
for overflow to fix the issue.

338be53ed3 Remove the obsolete reference to /file_contexts.
This file no longer exists:
- /file_contexts has been split into plat_file_contexts and
  nonplat_file_contexts since commit
  b236eb6ca204cefcb926e19bd5682f9dcad4021d (system/sepolicy).
- It was named /file_contexts.bin prior to the split.

'-S file_contexts' is also no longer required by e2fsdroid, since commit
2fff6fb036cbbb6dedd7da3d208b312a9038a5ce (external/e2fsprogs). It will
load the file contexts via libselinux.

d13b6cf29c recovery: replacing fs_mgr_read_fstab() with new fs_mgr APIs
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()

abb8f7785e recovery: Allow "Mount /system" for system_root_image.
When system images contain the root directory, there is no entry of
"/system" in the fstab. Change it to look for "/" instead if
ro.build.system_root_image is true. We actually mount the partition
to /system_root instead, and create a symlink to /system_root/system
for /system. This allows "adb shell" to work properly.

e853e96b40 always use volume mount option when mounting a partition
From ROS, if enable adb using the vol.up and vol.down buttons, the
/system partition is mounted by the function ensure_path_mounted() but
with hardcoded mount options.  As a consequence, the blocks are
modified and the reboot in MOS is blocked by the dm_verity feature
that detects a corruption.

This patch forces the function ensure_path_mounted() to use the mount
options from the volume structure, that were previously read from the
fstab.

99916f0496 do verification and extraction on memory, not files
Changes minzip and recovery's file signature verification to work on
memory regions, rather than files.

For packages which are regular files, install.cpp now mmap()s them
into memory and then passes the mapped memory to the verifier and to
the minzip library.

Support for files which are raw block maps (which will be used when we
have packages written to encrypted data partitions) is present but
largely untested so far.
