* AOSP: android/perms.c: clean up error handlingNick Kralevich2018-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a number of error conditions which, due to the way ext2fs_dir_iterate2 operates, would not be propagated to the upper layers of the call stack. As a result, certain error conditions, such as not having enough room to allocate blocks for SELinux labels, would fail silently, instead of causing a compile failure. As suggested in https://android-review.googlesource.com/c/platform/external/e2fsprogs/+/324363 , add a error field to the caller's private data structure, and use the bit in the field to indicate an error condition. Now, certain errors which were silently ignored will cause a compile failure when compiling Android. Test: Artifically modify selabel_lookup() to return a failure, and verify Android doesn't compile. Test: Verify Android compiles under normal circumstances. Test: Artifically modify ino_add_xattr() to return a failure, and verify Android doesn't compile.

* AOSP: e2fsdroid and mke2fs are dynamic executable in recovery partitionJiyong Park2018-06-27
| | | | | | | | | | | | | | | | | The two utilities are now converted to dynamic executables as shared libraries are supported in recovery mode. As part of the conversion, shared libraries that are depended from them are also marked as recovery_available: true. Bug: 79146551 Test: adb reboot recovery, and select 'Wipe data/factory reset'.

* AOSP: Standarize on VFS_CAP_REVISION_2Nick Kralevich2018-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In https://github.com/torvalds/linux/commit/8db6c34f1dbc8 , namespaced file capabilities were introduced. That change updated VFS_CAP_REVISION from VFS_CAP_REVISION_2 to VFS_CAP_REVISION_3. Android code is written assuming v2 capabilities, and the code will break if we naively try to treat a v2 structure as a v3 structure. So don't even try. Android kernels prior to v4.14 will not support this extended capability structure, so attempting to set such capabilities will ultimately fail. With 8db6c34f1dbc8, it appears that attempting to read a v3 capabilities xattr will always downgrade the capability to a v2 capability, so it really doesn't make sense to look for a v3 capability. Android capabilities are only created at /system and /vendor filesystem creation time by host tools. Android processes, within or outside a namespace, are not permitted CAP_SETFCAP (https://android-review.googlesource.com/c/platform/system/sepolicy/+/547801/1/public/domain.te line 1101). So we should never have to deal with a v3 capability other than those that might appear on the /system / /vendor partition at a future date by a future author.

* | libext2fs: add ea_inode support to set xattrTahsin Erdogan2017-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a major update to how we decide where to put extended attributes. The main motivation is to enable creating values in extended attribute inodes. While doing this, we want to implement a behavior that is as close to kernel as possible. Existing set ea code deviates from kernel behavior which makes it harder to implement ea_inode feature: - kernel only sorts ea entries in xattr block, e2fsprogs implementation sorts all entries on every update. - e2fsprogs implementation shuffled things on every update so the order of updates does not matter. Kernel does not reshuffle things. - e2fsprogs could evacuate entries from inode body to xattr block and vice versa. This behavior does not exist in kernel. Such differences could lead to inconsistent behavior between fuse2fs and a kernel mount. With ea_inode feature, we also need to decide whether to put a value in an inode or keep it 'inline'. In kernel implementation this depends on current placement of entries. To close the behavioral gap, ext2fs_xattr_set() now takes over the decision about where to place ea values. This also allows it to raise errors early instead of delaying them to a separate ext2fs_xattrs_write() call later.

* | AOSP: HACK: android: exit(1) if selabel_lookup failsNick Kralevich2017-05-23

There's a bunch of things wrong: 1) -1 does not appear to be a legal errcode_t value. The appropriate return value appears to be DIRENT_ABORT. 2) A return value of DIRENT_ABORT is ignored by the upper layers of the code. 3) Attempting to fix the upper layers of the code to not ignore DIRENT_ABORT results in complaints about not being able to create /lost+found. Call stack: - main - android_configure_fs - __android_configure_fs - ext2fs_dir_iterate2 - ext2fs_block_iterate3 - ext2fs_process_dir_block - walk_dir - ext2fs_dir_iterate2 - ext2fs_block_iterate3 - ext2fs_process_dir_block - walk_dir - ext2fs_dir_iterate2 - ext2fs_block_iterate3 - ext2fs_process_dir_block - androidify_inode - set_selinux_xattr I'm honestly not sure how to fix this, so just throw an exit(1) in there, to make sure the program dies a horrible death if selabel_lookup() fails. This is much better than the alternative of e2fsdroid returning success with an improperly labeled file.

* contrib: script to create minified ext4 image from a directoryDarrick J. Wong2015-05-05
| | | | | | | | | | | The dir2fs script converts a directory into a minimized ext4 filesystem. FS creation parameters are tweaked to reduce as much FS overhead as possible, and to leave as few unused blocks and inodes as possible. Given that mke2fs -d lays out files linearly from the beginning of the FS, using resize2fs -M is not as horrible as it usually is. Signed-off-by: Darrick J.
