sound updates for 4.8
Majority of this update is about ASoC, including a few new drivers,
and the rest are mostly minor changes. The only substantial change in
ALSA core is about the additional error handling in the
compress-offload API. Below are highlights:
- Add the error propagating support in compress-offload API
- HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the
default mixer setup change ot turn off the loopback
- Lots of updates for ASoC Intel drivers, mostly board support and bug
fixing, and to the NAU8825 driver
- Work on generalizing bits of simple-card to allow more code sharing
with the Renesas rsrc-card (which can't use simple-card due to DPCM)
- Removal of the Odroid X2 driver due to replacement with simple-card
- Support for several new Mediatek platforms and associated boards
- New ASoC drivers for Allwinner A10, Analog Devices ADAU7002, Broadcom
Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960 and MAX98504,
Realtek RT5514 and Wolfson WM8758

Pull sound updates from Takashi Iwai:
"The majority of this update is about ASoC, including a few new
drivers, and the rest are mostly minor changes. The only substantial
change in ALSA core is about the additional error handling in the
compress-offload API. Below are highlights:
- Add the error propagating support in compress-offload API
- HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the
default mixer setup change ot turn off the loopback
- Lots of updates for ASoC Intel drivers, mostly board support and
bug fixing, and to the NAU8825 driver
- Work on generalizing bits of simple-card to allow more code sharing
with the Renesas rsrc-card (which can't use simple-card due to DPCM)
- Removal of the Odroid X2 driver due to replacement with simple-card
- Support for several new Mediatek platforms and associated boards
- New ASoC drivers for Allwinner A10, Analog Devices ADAU7002,
Broadcom Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960
and MAX98504, Realtek RT5514 and Wolfson WM8758"

random: Fix crashes with sparse node ids
On a system with sparse node ids, eg. a powerpc system with 4 nodes
numbered like so:
node 0: [mem 0x0000000000000000-0x00000007ffffffff]
node 1: [mem 0x0000000800000000-0x0000000fffffffff]
node 16: [mem 0x0000001000000000-0x00000017ffffffff]
node 17: [mem 0x0000001800000000-0x0000001fffffffff]
The code in rand_initialize() will allocate 4 pointers for the pool
array, and initialise them correctly.
However when go to use the pool, in eg. extract_crng(), we use the
numa_node_id() to index into the array. For the higher numbered node ids
this leads to random memory corruption, depending on what was kmalloc'ed
adjacent to the pool array.
Fix it by using nr_node_ids to size the pool array.

NFS client updates for Linux 4.8
Highlights include:
Stable bugfixes:
- nfs: don't create zero-length requests
- Several LAYOUTGET bugfixes
Features:
- Several performance related features
- More aggressive caching when we can rely on close-to-open cache
consistency
- Remove serialisation of O_DIRECT reads and writes
- Optimise several code paths to not flush to disk unnecessarily. However
allow for the idiosyncracies of pNFS for those layout types that need
to issue a LAYOUTCOMMIT before the metadata can be updated on the server.
- SUNRPC updates to the client data receive path
- pNFS/SCSI support RH/Fedora dm-mpath device nodes
- pNFS files/flexfiles can now use unprivileged ports when the generic NFS
mount options allow it.
Bugfixes:
- Don't use RDMA direct data placement together with data integrity or
privacy security flavours
- Remove the RDMA ALLPHYSICAL memory registration mode as it has potential
security holes.
- Several layout recall fixes to improve NFSv4.1 protocol compliance.
- Fix an Oops in the pNFS files and flexfiles connection setup to the DS
- Allow retry of operations that used a returned delegation stateid
- Don't mark the inode as revalidated if a LAYOUTCOMMIT is outstanding
- Fix writeback races in nfs4_copy_range() and nfs42_proc_deallocate()

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull userns vfs updates from Eric Biederman:
"This tree contains some very long awaited work on generalizing the
user namespace support for mounting filesystems to include filesystems
with a backing store. The real world target is fuse but the goal is
to update the vfs to allow any filesystem to be supported. This
patchset is based on a lot of code review and testing to approach that
goal.
While looking at what is needed to support the fuse filesystem it
became clear that there were things like xattrs for security modules
that needed special treatment. That the resolution of those concerns
would not be fuse specific. That sorting out these general issues
made most sense at the generic level, where the right people could be
drawn into the conversation, and the issues could be solved for
everyone.
At a high level what this patchset does a couple of simple things:
- Add a user namespace owner (s_user_ns) to struct super_block.
- Teach the vfs to handle filesystem uids and gids not mapping into
to kuids and kgids and being reported as INVALID_UID and
INVALID_GID in vfs data structures.
By assigning a user namespace owner filesystems that are mounted with
only user namespace privilege can be detected. This allows security
modules and the like to know which mounts may not be trusted. This
also allows the set of uids and gids that are communicated to the
filesystem to be capped at the set of kuids and kgids that are in the
owning user namespace of the filesystem.
One of the crazier corner casees this handles is the case of inodes
whose i_uid or i_gid are not mapped into the vfs. Most of the code
simply doesn't care but it is easy to confuse the inode writeback path
so no operation that could cause an inode write-back is permitted for
such inodes (aka only reads are allowed).
This set of changes starts out by cleaning up the code paths involved
in user namespace permirted mounts. Then when things are clean enough
adds code that cleanly sets s_user_ns. Then additional restrictions
are added that are possible now that the filesystem superblock
contains owner information.
These changes should not affect anyone in practice, but there are some
parts of these restrictions that are changes in behavior.
- Andy's restriction on suid executables that does not honor the
suid bit when the path is from another mount namespace (think
/proc/[pid]/fd/) or when the filesystem was mounted by a less
privileged user.
- The replacement of the user namespace implicit setting of MNT_NODEV
with implicitly setting SB_I_NODEV on the filesystem superblock
instead.
Using SB_I_NODEV is a stronger form that happens to make this state
user invisible. The user visibility can be managed but it caused
problems when it was introduced from applications reasonably
expecting mount flags to be what they were set to.
There is a little bit of work remaining before it is safe to support
mounting filesystems with backing store in user namespaces, beyond
what is in this set of changes.
- Verifying the mounter has permission to read/write the block device
during mount.
- Teaching the integrity modules IMA and EVM to handle filesystems
mounted with only user namespace root and to reduce trust in their
security xattrs accordingly.
- Capturing the mounters credentials and using that for permission
checks in d_automount and the like. (Given that overlayfs already
does this, and we need the work in d_automount it make sense to
generalize this case).
Furthermore there are a few changes that are on the wishlist:
- Get all filesystems supporting posix acls using the generic posix
acls so that posix_acl_fix_xattr_from_user and
posix_acl_fix_xattr_to_user may be removed. [Maintainability]
- Reducing the permission checks in places such as remount to allow
the superblock owner to perform them.
- Allowing the superblock owner to chown files with unmapped uids and
gids to something that is mapped so the files may be treated
normally.
I am not considering even obvious relaxations of permission checks
until it is clear there are no more corner cases that need to be
locked down and handled generically.
Many thanks to Seth Forshee who kept this code alive, and putting up
with me rewriting substantial portions of what he did to handle more
corner cases, and for his diligent testing and reviewing of my
changes"

documentation: da9052: Update regulator bindings names to match DA9052/53 DTS expectations
Buck and LDO binding name changes.
The binding names for the regulators have been changed to match the current
expectation from existing device tree source files.
This fix rectifies the disparity between what currently exists in some
.dts[i] board files and what is listed in this binding document. This
change re-aligns those differences and also brings the binding document
in-line with the expectations of the product datasheet from Dialog
Semiconductor.
Bucks and LDOs now follow the expected notation:
{ buck1, buck2, buck3, buck4 }
{ ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10 }

objtool: Resync x86 instruction decoder with the kernel's
This fixes the following warning:
Warning: objtool: x86 instruction decoder differs from kernel
Unfortunately we have three identical copies of the x86 instruction
decoder in the kernel tree that have to be manually kept in sync.
It's on my TODO list to at least library-ize the ones in the tools
subdir so we'd only have two of them instead of three. In the meantime,
here's another manual sync.

objtool: Support new GCC 6 switch jump table pattern
This fixes some false positive objtool warnings seen with gcc 6.1.1: kernel/trace/ring_buffer.o: warning: objtool: ring_buffer_read_page()+0x36c: sibling call from callable instruction with changed frame pointer arch/x86/kernel/reboot.o: warning: objtool: native_machine_emergency_restart()+0x139: sibling call from callable instruction with changed frame pointer lib/xz/xz_dec_stream.o: warning: objtool: xz_dec_run()+0xc2: sibling call from callable instruction with changed frame pointer With GCC 6, a new code pattern is sometimes used to access a switch statement jump table in .rodata, which objtool doesn't yet recognize: mov [rodata addr],%reg1 ... some instructions ... jmpq *(%reg1,%reg2,8) Add support for detecting that pattern. The detection code is rather crude, but it's still effective at weeding out false positives and catching real warnings. It can be refined later once objtool starts reading DWARF CFI.

perf/urgent fix:
- Fix the tools/vm/ build by making libapi provide the str_error_c function, that libapi uses but wasn't part of the list of objects linked with tools/vm/ programs.

fuse: fuse_flush must check mapping->flags for errors
fuse_flush() calls write_inode_now() that triggers writeback, but actual
writeback will happen later, on fuse_sync_writes(). If an error happens,
fuse_writepage_end() will set error bit in mapping->flags. So, we have to
check mapping->flags after fuse_sync_writes().

Due to implementation of fuse writeback filemap_write_and_wait_range() does
not catch errors. We have to do this directly after fuse_sync_writes()

x86/power/64: Fix hibernation return address corruption
In kernel bug 150021, a kernel panic was reported when restoring a hibernate image. Only a picture of the oops was reported, so I can't paste the whole thing here. But here are the most interesting parts: kernel tried to execute NX-protected page - exploit attempt? (uid: 0) BUG: unable to handle kernel paging request at ffff8804615cfd78 ... RIP: ffff8804615cfd78 RSP: ffff8804615f0000 RBP: ffff8804615cfdc0 ... Call Trace: do_signal+0x23 exit_to_usermode_loop+0x64 ... The RIP is on the same page as RBP, so it apparently started executing on the stack. The bug was bisected to commit |
