uncrypt can read a file on an encrypted filesystem and rewrite it to the same blocks on the underlying (unencrypted) block device. This destroys the contents of the file as far as the encrypted filesystem is concerned, but allows the data to be read without the encryption key if you know which blocks of the raw device to access. uncrypt produces a "block map" file which lists the blocks that contain the file. For unencrypted filesystem, uncrypt will produce the block map without touching the data. Bug: 12188746 Change-Id: Ib7259b9e14dac8af406796b429d58378a00c7c63
When going into recovery mode withoug recovery command file present, uncrypt crashes and the device gets stuck and eventually shuts down. Check that the command file is present before trying to read from it. Change-Id: If0192d597032be0067738e437188d92993ce56f7

If recovery is invoked with a package somewhere other than /data, leave it alone. Change-Id: Ief358b53df467ae24a65e30e7a631da59bf13683

Something is leaving behind wipe commands in the BCB area of the /misc partition. We don't know what is doing that. It should always be safe to zero out that area from uncrypt, though (because if uncrypt is running then it's got the command we want in the recovery command file rather than the BCB). Bug: 16715412 Change-Id: Iad01124287f13b80ff71d6371db6371f43c43211
Opening the misc block device in read-write mode runs afoul of SELinux, which keeps the wipe code from working. Fix. Also change various things to log to logcat so we can see them happening, for future debugging. Bug: 16715412 Change-Id: Ia14066f0a371cd605fcb544547b58a41acca70b9
Always create the block map for packages on /data; don't only look at the encryptable/encrypted flags. Bug: 17395453 Change-Id: Iaa7643a32898328277841e324305b9419a9e071c
