commit 4617f564c06117c7d1b611be49521a4430042287 upstream.
When calling a dm ioctl that doesn't process any data
(IOCTL_FLAGS_NO_PARAMS), the contents of the data field in struct
dm_ioctl are left initialized. Current code is incorrectly extending
the size of data copied back to user, causing the contents of kernel
stack to be leaked to user. Fix by only copying contents before data
and allow the functions processing the ioctl to override.

commit 816b0acf3deb6d6be5d0519b286fdd4bafade905 upstream.
If first_bad == this_sector when we get the WriteMostly disk
in read_balance(), valid disk will be returned with zero
max_sectors. It'll lead to a dead loop in make_request(), and
OOM will happen because of endless allocation of struct bio.
Since we can't get data from this disk in this case, so
continue for another disk.

If androidboot.vbmeta.device is set and points to a device with vbmeta
magic, this header will be overwritten upon an irrecoverable dm-verity
error. The side-effect of this is that the slot will fail to verify on
next reboot, effectively triggering the boot loader to fallback to
another slot. This work both if the vbmeta struct is at the start of a
partition or if there's an AVB footer at the end.
This code is based on drivers/md/dm-verity-chromeos.c from ChromiumOS.

commit f5fe1b51905df7cfe4fdfd85c5fb7bc5b71a094f upstream.
Commit 79bd99596b73 ("blk: improve order of bio handling in generic_make_request()")
changed current->bio_list so that it did not contain *all* of the
queued bios, but only those submitted by the currently running
make_request_fn.
There are two places which walk the list and requeue selected bios,
and others that check if the list is empty. These are no longer
correct.
So redefine current->bio_list to point to an array of two lists, which
contain all queued bios, and adjust various code to test or walk both
lists.

If androidboot.vbmeta.device is set and points to a device with vbmeta
magic, this header will be overwritten upon an irrecoverable dm-verity
error. The side-effect of this is that the slot will fail to verify on
next reboot, effectively triggering the boot loader to fallback to
another slot. This work both if the vbmeta struct is at the start of a
partition or if there's an AVB footer at the end.
This code is based on drivers/md/dm-verity-chromeos.c from ChromiumOS.

commit 9b622e2bbcf049c82e2550d35fb54ac205965f50 upstream.
md pending write counter must be incremented after bio is split,
otherwise it gets decremented too many times in end bio callback and
becomes negative.

commit 61eb2b43b99ebdc9bc6bc83d9792257b243e7cb3 upstream.
Neil Brown pointed out a potential deadlock in raid 10 code with
bio_split/chain. The raid1 code could have the same issue, but recent
barrier rework makes it less likely to happen. The deadlock happens in
below sequence:
1. generic_make_request(bio), this will set current->bio_list
2. raid10_make_request will split bio to bio1 and bio2
3. __make_request(bio1), wait_barrer, add underlayer disk bio to
current->bio_list
4. __make_request(bio2), wait_barrer
If raise_barrier happens between 3 & 4, since wait_barrier runs at 3,
raise_barrier waits for IO completion from 3. And since raise_barrier
sets barrier, 4 waits for raise_barrier. But IO from 3 can't be
dispatched because raid10_make_request() doesn't finished yet.
The solution is to adjust the IO ordering. Quotes from Neil:
"
It is much safer to:
if (need to split) {
split = bio_split(bio, ...)
bio_chain(...)
make_request_fn(split);
generic_make_request(bio);
} else
make_request_fn(mddev, bio);
This way we first process the initial section of the bio (in 'split')
which will queue some requests to the underlying devices. These
requests will be queued in generic_make_request.
Then we queue the remainder of the bio, which will be added to the end
of the generic_make_request queue.
Then we return.
generic_make_request() will pop the lower-level device requests off the
queue and handle them first. Then it will process the remainder
of the original bio once the first section has been fully processed.
"
Note, this only happens in read path. In write path, the bio is flushed to
underlaying disks either by blk flush (from schedule) or offladed to raid1/10d.
It's queued in current->bio_list.

dm-android-verity depends on optional kernel command line parameters.
When compiled as module the __setup macro ends up being a no-op
resulting in the following warnings:

To start Treble VTS test, a single AOSP system.img will be flashed onto
the device. The size of AOSP system.img might be different than the
system partition size on device, making locating verity metadata fail
(at the last fixed size of the partition).
This change allows disabling dm-verity on system partition when the
device is unlocked (orange device state) with invalid metadata.
BUG: 35603549
Test: boot device with a different-sized system.img, checks verity is
not enabled via:
"adb shell getprop | grep partition.system.verified"

The fec_header structure is generated build time and stored on disk.
The fec_header might be build on a 64 bits machine while it is read
per a 32 bits device or the other way around. In such situations, the
fec_header fields are not aligned as expected by the device and it
fails to read the fec_header structure.
This patch makes the fec_header packed.
