* Add android::fs_mgr namespace for new Fstab codeTom Cherry2019-01-311-4/+5
| | | | | | | | | | | | | | | Also add libfstab dependencies where needed. Previously the `typedef struct FstabEntry Volume;` line served to both define a `struct FstabEntry` as well as alias Volume to it. With the new namespace for android::fs_mgr::FstabEntry, `struct FstabEntry` isn't compatible anymore, so we need to alias Volume to the real android::fs_mgr::FstabEntry. In doing so, we need to include <fstab/fstab.h> and this requires libfstab as a library, which a few modules did not have before. Test: treehugger Change-Id: I655209a0efb304b3e0568db0748bd5cf7cecbdb7

* recovery: Fix mounting /system with dynamic partitions.David Anderson2018-10-301-0/+25
| | | | | | | | | | | | | | | When using dynamic partitions, the blk_device field in fstab_rec must be translated to a /dev/block/dm-N node with fs_mgr_update_logical_partition. However, init will not have created these nodes to begin with since CreateLogicalPartitions is not called in recovery. This patch addresses both issues. Note that flashing system through fastbootd will not work while /system is mounted. Bug: 118634720 Test: manual test Change-Id: I06c83309d09eab6b65245b1ed10c51d05398f23e

* roots: Fix an issue with volume_for_path().Tao Bao2017-10-021-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | The earlier commit in 2dfc1a38982c4052bb32bc7fc06edeadf3908fb9 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | roots: volume_for_path() parses and tries prefixes.Tao Bao2017-09-271-1/+20
|/ | | | | | | | | | | | | | | | 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.

* | do verification and extraction on memory, not filesDoug Zongker2014-01-161-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | recovery: wipe encryption metadata along with data partitionDoug Zongker2013-12-131-1/+26
|/ | | | | | | | | This assumes that the metadata is correctly defined in fstab. Which apparently some devices don't do. Bug: 8766487 Bug: 12112624 Change-Id: I1b14b9d4c888e9348527984be3dce04bdd9f4de0
* recovery: install packages in a known mount environmentDoug Zongker2013-08-211-0/+19
| | | | | | | | | | | When installing a package, we should have /tmp and /cache mounted and nothing else. Ensure this is true by explicitly mounting them and unmounting everything else as the first step of every install. Also fix an error in the progress bar that crops up when you do multiple package installs in one instance of recovery. Change-Id: I4837ed707cb419ddd3d9f6188b6355ba1bcfe2b2
* Move to using the new unified fstab in recovery.Ken Sumrall2013-02-201-110/+30
| | | | | | | Instead of reading it's own fstab, have recovery invoke fs_mgr to read the unified fstab. Change-Id: I80c75d2c53b809ac60a4a69f0ef7ebfa707c39e9
