5e19d3fa33 FROMLIST: fscrypt: add FS_IOC_GET_ENCRYPTION_NONCE ioctl
Add an ioctl FS_IOC_GET_ENCRYPTION_NONCE which retrieves the nonce from
an encrypted file or directory.  The nonce is the 16-byte random value
stored in the inode's encryption xattr.  It is normally used together
with the master key to derive the inode's actual encryption key.

The nonces are needed by automated tests that verify the correctness of
the ciphertext on-disk.  Except for the IV_INO_LBLK_64 case, there's no
way to replicate a file's ciphertext without knowing that file's nonce.

The nonces aren't secret, and the existing ciphertext verification tests
in xfstests retrieve them from disk using debugfs or dump.f2fs.  But in
environments that lack these debugging tools, getting the nonces by
manually parsing the filesystem structure would be very hard.

To make this important type of testing much easier, let's just add an
ioctl that retrieves the nonce.

c7d5d7d971 fscrypt: include <linux/ioctl.h> in UAPI header
<linux/fscrypt.h> defines ioctl numbers using the macros like _IOWR()
which are defined in <linux/ioctl.h>, so <linux/ioctl.h> should be
included as a prerequisite, like it is in many other kernel headers.

In practice this doesn't really matter since anyone referencing these
ioctl numbers will almost certainly include <sys/ioctl.h> too in order
to actually call ioctl().  But we might as well fix this.

2c2b751b6f fscrypt: support passing a keyring key to FS_IOC_ADD_ENCRYPTION_KEY
Extend the FS_IOC_ADD_ENCRYPTION_KEY ioctl to allow the raw key to be
specified by a Linux keyring key, rather than specified directly.

This is useful because fscrypt keys belong to a particular filesystem
instance, so they are destroyed when that filesystem is unmounted.
Usually this is desired.  But in some cases, userspace may need to
unmount and re-mount the filesystem while keeping the keys, e.g. during
a system update.  This requires keeping the keys somewhere else too.

The keys could be kept in memory in a userspace daemon.  But depending
on the security architecture and assumptions, it can be preferable to
keep them only in kernel memory, where they are unreadable by userspace.

We also can't solve this by going back to the original fscrypt API
(where for each file, the master key was looked up in the process's
keyring hierarchy) because that caused lots of problems of its own.

Therefore, add the ability for FS_IOC_ADD_ENCRYPTION_KEY to accept a
Linux keyring key.  This solves the problem by allowing userspace to (if
needed) save the keys securely in a Linux keyring for re-provisioning,
while still using the new fscrypt key management ioctls.

This is analogous to how dm-crypt accepts a Linux keyring key, but the
key is then stored internally in the dm-crypt data structures rather
than being looked up again each time the dm-crypt device is accessed.

Use a custom key type "fscrypt-provisioning" rather than one of the
existing key types such as "logon".  This is strongly desired because it
enforces that these keys are only usable for a particular purpose: for
fscrypt as input to a particular KDF.  Otherwise, the keys could also be
passed to any kernel API that accepts a "logon" key with any service
prefix, e.g. dm-crypt, UBIFS, or (recently proposed) AF_ALG.  This would
risk leaking information about the raw key despite it ostensibly being
unreadable.  Of course, this mistake has already been made for multiple
kernel APIs; but since this is a new API, let's do it right.

This patch has been tested using an xfstest which I wrote to test it.

8173487568 ANDROID: fscrypt: add support for hardware-wrapped keys
To prevent keys from being compromised if an attacker acquires read
access to kernel memory, some inline encryption hardware supports
protecting the keys in hardware without software having access to or the
ability to set the plaintext keys.  Instead, software only sees "wrapped
keys", which may differ on every boot.  The keys can be initially
generated either by software (in which case they need to be imported to
hardware to be wrapped), or directly by the hardware.

Add support for this type of hardware by allowing keys to be flagged as
hardware-wrapped and encryption policies to be flagged as needing a
hardware-wrapped key.  When used, fscrypt will pass the wrapped key
directly to the inline encryption hardware to encrypt file contents.
The hardware is responsible for internally unwrapping the key and
deriving the actual file contents encryption key.

fscrypt also asks the inline encryption hardware to derive a
cryptographically isolated software "secret", which fscrypt then uses as
the master key for all other purposes besides file contents encryption,
e.g. to derive filenames encryption keys and the key identifier.

d0a44e4829 UPSTREAM: kcov: fix struct layout for kcov_remote_arg
(Upstream commit a69b83e1ae7f6c5ff2cc310870c1708405d86be2.)

Make the layout of kcov_remote_arg the same for 32-bit and 64-bit code.
This makes it more convenient to write userspace apps that can be
compiled into 32-bit or 64-bit binaries and still work with the same
64-bit kernel.

Also use proper __u32 types in uapi headers instead of unsigned ints.

854ac5dee5 Input: input_event - fix struct padding on sparc64
commit f729a1b0f8 upstream.

Going through all uses of timeval, I noticed that we screwed up
input_event in the previous attempts to fix it:

The time fields now match between kernel and user space, but all following
fields are in the wrong place.

Add the required padding that is implied by the glibc timeval definition
to fix the layout, and use a struct initializer to avoid leaking kernel
stack data.

75579189e9 UPSTREAM: kcov: remote coverage support
(Upstream commit eec028c9386ed1a692aa01a85b55952202b41619.)

Patch series " kcov: collect coverage from usb and vhost", v3.

This patchset extends kcov to allow collecting coverage from backgound
kernel threads.  This extension requires custom annotations for each of
the places where coverage collection is desired.  This patchset
implements this for hub events in the USB subsystem and for vhost
workers.  See the first patch description for details about the kcov
extension.  The other two patches apply this kcov extension to USB and
vhost.

Examples of other subsystems that might potentially benefit from this
when custom annotations are added (the list is based on
process_one_work() callers for bugs recently reported by syzbot):

1. fs: writeback wb_workfn() worker,
2. net: addrconf_dad_work()/addrconf_verify_work() workers,
3. net: neigh_periodic_work() worker,
4. net/p9: p9_write_work()/p9_read_work() workers,
5. block: blk_mq_run_work_fn() worker.

These patches have been used to enable coverage-guided USB fuzzing with
syzkaller for the last few years, see the details here:

  https://github.com/google/syzkaller/blob/master/docs/linux/external_fuzzing_usb.md

This patchset has been pushed to the public Linux kernel Gerrit
instance:

  https://linux-review.googlesource.com/c/linux/kernel/git/torvalds/linux/+/1524

This patch (of 3):

Add background thread coverage collection ability to kcov.

With KCOV_ENABLE coverage is collected only for syscalls that are issued
from the current process.  With KCOV_REMOTE_ENABLE it's possible to
collect coverage for arbitrary parts of the kernel code, provided that
those parts are annotated with kcov_remote_start()/kcov_remote_stop().

This allows to collect coverage from two types of kernel background
threads: the global ones, that are spawned during kernel boot in a
limited number of instances (e.g.  one USB hub_event() worker thread is
spawned per USB HCD); and the local ones, that are spawned when a user
interacts with some kernel interface (e.g.  vhost workers).

To enable collecting coverage from a global background thread, a unique
global handle must be assigned and passed to the corresponding
kcov_remote_start() call.  Then a userspace process can pass a list of
such handles to the KCOV_REMOTE_ENABLE ioctl in the handles array field
of the kcov_remote_arg struct.  This will attach the used kcov device to
the code sections, that are referenced by those handles.

Since there might be many local background threads spawned from
different userspace processes, we can't use a single global handle per
annotation.  Instead, the userspace process passes a non-zero handle
through the common_handle field of the kcov_remote_arg struct.  This
common handle gets saved to the kcov_handle field in the current
task_struct and needs to be passed to the newly spawned threads via
custom annotations.  Those threads should in turn be annotated with
kcov_remote_start()/kcov_remote_stop().

Internally kcov stores handles as u64 integers.  The top byte of a
handle is used to denote the id of a subsystem that this handle belongs
to, and the lower 4 bytes are used to denote the id of a thread instance
within that subsystem.  A reserved value 0 is used as a subsystem id for
common handles as they don't belong to a particular subsystem.  The
bytes 4-7 are currently reserved and must be zero.  In the future the
number of bytes used for the subsystem or handle ids might be increased.

When a particular userspace process collects coverage by via a common
handle, kcov will collect coverage for each code section that is
annotated to use the common handle obtained as kcov_handle from the
current task_struct.  However non common handles allow to collect
coverage selectively from different subsystems.

17a7f9d865 netfilter: uapi: Avoid undefined left-shift in xt_sctp.h
[ Upstream commit 164166558a ]

With 'bytes(__u32)' being 32, a left-shift of 31 may happen which is
undefined for the signed 32-bit value 1. Avoid this by declaring 1 as
unsigned.

6f7bd451e3 statx: define STATX_ATTR_VERITY
Add a statx attribute bit STATX_ATTR_VERITY which will be set if the
file has fs-verity enabled.  This is the statx() equivalent of
FS_VERITY_FL which is returned by FS_IOC_GETFLAGS.

This is useful because it allows applications to check whether a file is
a verity file without opening it.  Opening a verity file can be
expensive because the fsverity_info is set up on open, which involves
parsing metadata and optionally verifying a cryptographic signature.

This is analogous to how various other bits are exposed through both
FS_IOC_GETFLAGS and statx(), e.g. the encrypt bit.

9ee51af526 fscrypt: add support for IV_INO_LBLK_64 policies
Inline encryption hardware compliant with the UFS v2.1 standard or with
the upcoming version of the eMMC standard has the following properties:

(1) Per I/O request, the encryption key is specified by a previously
    loaded keyslot.  There might be only a small number of keyslots.

(2) Per I/O request, the starting IV is specified by a 64-bit "data unit
    number" (DUN).  IV bits 64-127 are assumed to be 0.  The hardware
    automatically increments the DUN for each "data unit" of
    configurable size in the request, e.g. for each filesystem block.

Property (1) makes it inefficient to use the traditional fscrypt
per-file keys.  Property (2) precludes the use of the existing
DIRECT_KEY fscrypt policy flag, which needs at least 192 IV bits.

Therefore, add a new fscrypt policy flag IV_INO_LBLK_64 which causes the
encryption to modified as follows:

- The encryption keys are derived from the master key, encryption mode
  number, and filesystem UUID.

- The IVs are chosen as (inode_number << 32) | file_logical_block_num.
  For filenames encryption, file_logical_block_num is 0.

Since the file nonces aren't used in the key derivation, many files may
share the same encryption key.  This is much more efficient on the
target hardware.  Including the inode number in the IVs and mixing the
filesystem UUID into the keys ensures that data in different files is
nevertheless still encrypted differently.

Additionally, limiting the inode and block numbers to 32 bits and
placing the block number in the low bits maintains compatibility with
the 64-bit DUN convention (property (2) above).

Since this scheme assumes that inode numbers are stable (which may
preclude filesystem shrinking) and that inode and file logical block
numbers are at most 32-bit, IV_INO_LBLK_64 will only be allowed on
filesystems that meet these constraints.  These are acceptable
limitations for the cases where this format would actually be used.

Note that IV_INO_LBLK_64 is an on-disk format, not an implementation.
This patch just adds support for it using the existing filesystem layer
encryption.  A later patch will add support for inline encryption.

6db9b02e75 media: cec-funcs.h: add status_req checks
[ Upstream commit 9b211f9c5a ]

The CEC_MSG_GIVE_DECK_STATUS and CEC_MSG_GIVE_TUNER_DEVICE_STATUS commands
both have a status_req argument: ON, OFF, ONCE. If ON or ONCE, then the
follower will reply with a STATUS message. Either once or whenever the
status changes (status_req == ON).

If status_req == OFF, then it will stop sending continuous status updates,
but the follower will *not* send a STATUS message in that case.

This means that if status_req == OFF, then msg->reply should be 0 as well
since no reply is expected in that case.

6138e687c7 ptp: Introduce strict checking of external time stamp options.
User space may request time stamps on rising edges, falling edges, or
both.  However, the particular mode may or may not be supported in the
hardware or in the driver.  This patch adds a "strict" flag that tells
drivers to ensure that the requested mode will be honored.

When setting the dump's time-stamp, use ktime_get_real in addition to

3484eba91d FROMLIST: Add flags option to get xattr method paired to __vfs_getxattr
Add a flag option to get xattr method that could have a bit flag of
XATTR_NOSECURITY passed to it.  XATTR_NOSECURITY is generally then
set in the __vfs_getxattr path when called by security
infrastructure.

This handles the case of a union filesystem driver that is being
requested by the security layer to report back the xattr data.

For the use case where access is to be blocked by the security layer.

The path then could be security(dentry) ->
__vfs_getxattr(dentry...XATTR_NOSECURITY) ->
handler->get(dentry...XATTR_NOSECURITY) ->
__vfs_getxattr(lower_dentry...XATTR_NOSECURITY) ->
lower_handler->get(lower_dentry...XATTR_NOSECURITY)
which would report back through the chain data and success as
expected, the logging security layer at the top would have the
data to determine the access permissions and report back the target
context that was blocked.

Without the get handler flag, the path on a union filesystem would be
the errant security(dentry) -> __vfs_getxattr(dentry) ->
handler->get(dentry) -> vfs_getxattr(lower_dentry) -> nested ->
security(lower_dentry, log off) -> lower_handler->get(lower_dentry)
which would report back through the chain no data, and -EACCES.

For selinux for both cases, this would translate to a correctly
determined blocked access. In the first case with this change a correct avc
log would be reported, in the second legacy case an incorrect avc log
would be reported against an uninitialized u:object_r:unlabeled:s0
context making the logs cosmetically useless for audit2allow.

This patch series is inert and is the wide-spread addition of the
flags option for xattr functions, and a replacement of __vfs_getxattr
with __vfs_getxattr(...XATTR_NOSECURITY).

Pull clone3 stack argument update from Christian Brauner:
 "This changes clone3() to do basic stack validation and to set up the
  stack depending on whether or not it is growing up or down.

  With clone3() the expectation is now very simply that the .stack
  argument points to the lowest address of the stack and that
  .stack_size specifies the initial stack size. This is diferent from
  legacy clone() where the "stack" argument had to point to the lowest
  or highest address of the stack depending on the architecture.

  clone3() was released with 5.3. Currently, it is not documented and
  very unclear to userspace how the stack and stack_size argument have
  to be passed. After talking to glibc folks we concluded that changing
  clone3() to determine stack direction and doing basic validation is
  the right course of action.

  Note, this is a potentially user visible change. In the very unlikely
  case, that it breaks someone's use-case we will revert. (And then e.g.
  place the new behavior under an appropriate flag.)

  Note that passing an empty stack will continue working just as before.
  Breaking someone's use-case is very unlikely. Neither glibc nor musl
  currently expose a wrapper for clone3(). There is currently also no
  real motivation for anyone to use clone3() directly. First, because
  using clone{3}() with stacks requires some assembly (see glibc and
  musl). Second, because it does not provide features that legacy
  clone() doesn't. New features for clone3() will first happen in v5.5
  which is why v5.4 is still a good time to try and make that change now
  and backport it to v5.3.

  I did a codesearch on https://codesearch.debian.net, github, and
  gitlab and could not find any software currently relying directly on
  clone3(). I expect this to change once we land CLONE_CLEAR_SIGHAND
  which was a request coming from glibc at which point they'll likely
  start using it"

fa729c4df5 clone3: validate stack arguments
Validate the stack arguments and setup the stack depening on whether or not
it is growing down or up.

Legacy clone() required userspace to know in which direction the stack is
growing and pass down the stack pointer appropriately. To make things more
confusing microblaze uses a variant of the clone() syscall selected by
CONFIG_CLONE_BACKWARDS3 that takes an additional stack_size argument.
IA64 has a separate clone2() syscall which also takes an additional
stack_size argument. Finally, parisc has a stack that is growing upwards.
Userspace therefore has a lot nasty code like the following:

 #define __STACK_SIZE (8 * 1024 * 1024)
 pid_t sys_clone(int (*fn)(void *), void *arg, int flags, int *pidfd)
 {
         pid_t ret;
         void *stack;

         stack = malloc(__STACK_SIZE);
         if (!stack)
                 return -ENOMEM;

 #ifdef __ia64__
         ret = __clone2(fn, stack, __STACK_SIZE, flags | SIGCHLD, arg, pidfd);
 #elif defined(__parisc__) /* stack grows up */
         ret = clone(fn, stack, flags | SIGCHLD, arg, pidfd);
 #else
         ret = clone(fn, stack + __STACK_SIZE, flags | SIGCHLD, arg, pidfd);
 #endif
         return ret;
 }

or even crazier variants such as [3].

With clone3() we have the ability to validate the stack. We can check that
when stack_size is passed, the stack pointer is valid and the other way
around. We can also check that the memory area userspace gave us is fine to
use via access_ok(). Furthermore, we probably should not require
userspace to know in which direction the stack is growing. It is easy
for us to do this in the kernel and I couldn't find the original
reasoning behind exposing this detail to userspace.

/* Intentional user visible API change */
clone3() was released with 5.3. Currently, it is not documented and very
unclear to userspace how the stack and stack_size argument have to be
passed. After talking to glibc folks we concluded that trying to change
clone3() to setup the stack instead of requiring userspace to do this is
the right course of action.
Note, that this is an explicit change in user visible behavior we introduce
with this patch. If it breaks someone's use-case we will revert! (And then
e.g. place the new behavior under an appropriate flag.)
Breaking someone's use-case is very unlikely though. First, neither glibc
nor musl currently expose a wrapper for clone3(). Second, there is no real
motivation for anyone to use clone3() directly since it does not provide
features that legacy clone doesn't. New features for clone3() will first
happen in v5.5 which is why v5.4 is still a good time to try and make that
change now and backport it to v5.3. Searches on [4] did not reveal any
packages calling clone3().

(2) Per I/O request, the starting IV is specified by a 64-bit "data unit
    number" (DUN).  IV bits 64-127 are assumed to be 0.  The hardware
    automatically increments the DUN for each "data unit" of
    configurable size in the request, e.g. for each filesystem block.

Property (1) makes it inefficient to use the traditional fscrypt
per-file keys.  Property (2) precludes the use of the existing
DIRECT_KEY fscrypt policy flag, which needs at least 192 IV bits.

Therefore, add a new fscrypt policy flag IV_INO_LBLK_64 which causes the
encryption to modified as follows:

- The encryption keys are derived from the master key, encryption mode
  number, and filesystem UUID.

- The IVs are chosen as (inode_number << 32) | file_logical_block_num.
  For filenames encryption, file_logical_block_num is 0.

Since the file nonces aren't used in the key derivation, many files may
share the same encryption key.  This is much more efficient on the
target hardware.  Including the inode number in the IVs and mixing the
filesystem UUID into the keys ensures that data in different files is
nevertheless still encrypted differently.

Additionally, limiting the inode and block numbers to 32 bits and
placing the block number in the low bits maintains compatibility with
the 64-bit DUN convention (property (2) above).

Since this scheme assumes that inode numbers are stable (which may
preclude filesystem shrinking) and that inode and file logical block
numbers are at most 32-bit, IV_INO_LBLK_64 will only be allowed on
filesystems that meet these constraints.  These are acceptable
limitations for the cases where this format would actually be used.

Note that IV_INO_LBLK_64 is an on-disk format, not an implementation.
This patch just adds support for it using the existing filesystem layer
encryption.  A later patch will add support for inline encryption.

e81694723a ANDROID: media: increase video max frame number
Few userspace clients and drivers need more frames and
hence increase video max frame number from 32 to 64.
