x86/smpboot: Don't use mwait_play_dead() on AMD systems
commit da6fa7ef67f07108a1b0cb9fd9e7fcaabd39c051 upstream.
Recent AMD systems support using MWAIT for C1 state. However, MWAIT will
not allow deeper cstates than C1 on current systems.
play_dead() expects to use the deepest state available. The deepest state
available on AMD systems is reached through SystemIO or HALT. If MWAIT is
available, it is preferred over the other methods, so the CPU never reaches
the deepest possible state.
Don't try to use MWAIT to play_dead() on AMD systems. Instead, use CPUIDLE
to enter the deepest state advertised by firmware. If CPUIDLE is not
available then fallback to HALT.

x86/ipc: Fix x32 version of shmid64_ds and msqid64_ds
commit 1a512c0882bd311c5b5561840fcfbe4c25b8f319 upstream.
A bugfix broke the x32 shmid64_ds and msqid64_ds data structure layout
(as seen from user space) a few years ago: Originally, __BITS_PER_LONG
was defined as 64 on x32, so we did not have padding after the 64-bit
__kernel_time_t fields, After __BITS_PER_LONG got changed to 32,
applications would observe extra padding.
In other parts of the uapi headers we seem to have a mix of those
expecting either 32 or 64 on x32 applications, so we can't easily revert
the path that broke these two structures.
Instead, this patch decouples x32 from the other architectures and moves
it back into arch specific headers, partially reverting the even older
commit 73a2d096fdf2 ("x86: remove all now-duplicate header files").
It's not clear whether this ever made any difference, since at least
glibc carries its own (correct) copy of both of these header files,
so possibly no application has ever observed the definitions here.
Based on a suggestion from H.J. Lu, I tried out the tool from
https://github.com/hjl-tools/linux-header to find other such
bugs, which pointed out the same bug in statfs(), which also has
a separate (correct) copy in glibc.

builds")

libceph: validate con->state at the top of try_write()
commit 9c55ad1c214d9f8c4594ac2c3fa392c1c32431a7 upstream.
ceph_con_workfn() validates con->state before calling try_read() and
then try_write(). However, try_read() temporarily releases con->mutex,
notably in process_message() and ceph_con_in_msg_alloc(), opening the
window for ceph_con_close() to sneak in, close the connection and
release con->sock. When try_write() is called on the assumption that
con->state is still valid (i.e. not STANDBY or CLOSED), a NULL sock
gets passed to the networking stack:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000020
IP: selinux_socket_sendmsg+0x5/0x20
Make sure con->state is valid at the top of try_write() and add an
explicit BUG_ON for this, similar to try_read().

ASoC: fsl_esai: Fix divisor calculation failure at lower ratio
commit c656941df9bc80f7ec65b92ca73c42f8b0b62628 upstream.
When the desired ratio is less than 256, the savesub (tolerance)
in the calculation would become 0. This will then fail the loop-
search immediately without reporting any errors.
But if the ratio is smaller enough, there is no need to calculate
the tolerance because PM divisor alone is enough to get the ratio.
So a simple fix could be just to set PM directly instead of going
into the loop-search.

For AMBA devices with unconfigured driver override, the
"driver_override" sysfs virtual file is empty, while it contains
"(null)" for platform and PCI devices.
Make AMBA consistent with other buses by dropping the test for a NULL
pointer.
Note that contrary to popular belief, sprintf() handles NULL pointers
fine; they are printed as "(null)".

commit 46a16a2283f9e678a4e26829175e0c37a5191860 upstream.
Some Micron chips does not work well wrt Erase suspend for
boot blocks. This avoids the issue by not allowing Erase suspend
for the boot blocks for the 28F00AP30(1GBit) chip.

Assigned codec type.
This is an additional fix over 92f974df3460 ("ALSA: hda/realtek - New
vendor ID for ALC233").
[ More notes:
according to Kailang, the chip is 10ec:0235 bonding for ALC233b,
which is equivalent with ALC255. It's only used for Lenovo.
The chip needs no alc_process_coef_fw() for headset unlike ALC255. ]

ALSA: hda: Hardening for potential Spectre v1
commit 69fa6f19b95597618ab30438a27b67ad93daa7c7 upstream.
As recently Smatch suggested, one place in HD-audio hwdep ioctl codes
may expand the array directly from the user-space value with
speculation:
sound/pci/hda/hda_local.h:467 get_wcaps() warn: potential spectre issue
'codec->wcaps'
As get_wcaps() itself is a fairly frequently called inline function,
and there is only one single call with a user-space value, we replace
only the latter one to open-code locally with array_index_nospec()
hardening in this patch.

ALSA: seq: oss: Hardening for potential Spectre v1
commit 8d218dd8116695ecda7164f97631c069938aa22e upstream.
As Smatch recently suggested, a few places in OSS sequencer codes may
expand the array directly from the user-space value with speculation,
namely there are a significant amount of references to either
info->ch[] or dp->synths[] array:
sound/core/seq/oss/seq_oss_event.c:315 note_on_event() warn: potential
spectre issue 'info->ch' (local cap)
sound/core/seq/oss/seq_oss_event.c:362 note_off_event() warn: potential
spectre issue 'info->ch' (local cap)
sound/core/seq/oss/seq_oss_synth.c:470 snd_seq_oss_synth_load_patch()
warn: potential spectre issue 'dp->synths' (local cap)
sound/core/seq/oss/seq_oss_event.c:293 note_on_event() warn: potential
spectre issue 'dp->synths'
sound/core/seq/oss/seq_oss_event.c:353 note_off_event() warn: potential
spectre issue 'dp->synths'
sound/core/seq/oss/seq_oss_synth.c:506 snd_seq_oss_synth_sysex() warn:
potential spectre issue 'dp->synths'
sound/core/seq/oss/seq_oss_synth.c:580 snd_seq_oss_synth_ioctl() warn:
potential spectre issue 'dp->synths'
Although all these seem doing only the first load without further
reference, we may want to stay in a safer side, so hardening with
array_index_nospec() would still make sense.
We may put array_index_nospec() at each place, but here we take a
different approach:
- For dp->synths[], change the helpers to retrieve seq_oss_synthinfo
pointer directly instead of the array expansion at each place
- For info->ch[], harden in a normal way, as there are only a couple
of places
As a result, the existing helper, snd_seq_oss_synth_is_valid() is
replaced with snd_seq_oss_synth_info(). Also, we cover MIDI device
where a similar array expansion is done, too, although it wasn't
reported by Smatch.

ALSA: seq: oss: Fix unbalanced use lock for synth MIDI device
commit f5e94b4c6ebdabe0f602d796e0430180927521a0 upstream.
When get_synthdev() is called for a MIDI device, it returns the fixed
midi_synth_dev without the use refcounting. OTOH, the caller is
supposed to unreference unconditionally after the usage, so this would
lead to unbalanced refcount.
This patch corrects the behavior and keep up the refcount balance also
for the MIDI synth device.

In this patch, we put array_index_nospec() to the common
snd_ctl_get_ioff*() helpers instead of each caller. These helpers are
also referred from some drivers, too, and basically all usages are to
calculate the array index from the user-space value, hence it's better
to cover there.

syzbot is reporting crashes triggered by memory allocation fault injection
at tty_ldisc_get() [1]. As an attempt to handle OOM in a graceful way, we
have tried commit 5362544bebe85071 ("tty: don't panic on OOM in
tty_set_ldisc()"). But we reverted that attempt by commit a8983d01f9b7d600
("Revert "tty: don't panic on OOM in tty_set_ldisc()"") due to reproducible
crash. We should spend resource for finding and fixing race condition bugs
rather than complicate error paths for 2 * sizeof(void *) bytes allocation
failure.

tty: n_gsm: Fix DLCI handling for ADM mode if debug & 2 is not set
commit b2d89ad9c9682e795ed6eeb9ed455789ad6cedf1 upstream.
At least on droid 4 with control channel in ADM mode, there is no response
to Modem Status Command (MSC). Currently gsmtty_modem_update() expects to
have data in dlci->modem_rx unless debug & 2 is set. This means that on
droid 4, things only work if debug & 2 is set.
Let's fix the issue by ignoring empty dlci->modem_rx for ADM mode. In
the AMD mode, CMD_MSC will never respond and gsm_process_modem() won't
get called to set dlci->modem_rx.
And according to ts_127010v140000p.pdf, MSC is only relevant if basic
option is chosen, so let's test for that too.

tty: n_gsm: Fix long delays with control frame timeouts in ADM mode
commit e9ec22547986dd32c5c70da78107ce35dbff1344 upstream.
Commit ea3d8465ab9b ("tty: n_gsm: Allow ADM response in addition to UA for
control dlci") added support for DLCI to stay in Asynchronous Disconnected
Mode (ADM). But we still get long delays waiting for commands to other
DLCI to complete:
--> 5) C: SABM(P)
Q> 0) C: UIH(F)
Q> 0) C: UIH(F)
Q> 0) C: UIH(F)
...
This happens because gsm_control_send() sets cretries timer to T2 that is
by default set to 34. This will cause resend for T2 times for the control
frame. In ADM mode, we will never get a response so the control frame, so
retries are just delaying all the commands.
Let's fix the issue by setting DLCI_MODE_ADM flag after detecting the ADM
mode for the control DLCI. Then we can use that in gsm_control_send() to
set retries to 1. This means the control frame will be sent once allowing
the other end at an opportunity to switch from ADM to ABM mode.
Note that retries will be decremented in gsm_control_retransmit() so
we don't want to set it to 0 here.

virtio_console: free buffers after reset
commit a7a69ec0d8e4a58be7db88d33cbfa2912807bb2b upstream.
Console driver is out of spec. The spec says:
A driver MUST NOT decrement the available idx on a live
virtqueue (ie. there is no way to âunexposeâ buffers).
and it does exactly that by trying to detach unused buffers
without doing a device reset first.
Defer detaching the buffers until device unplug.
Of course this means we might get an interrupt for
a vq without an attached port now. Handle that by
discarding the consumed buffer.

For cleanup it's helpful to be able to simply scan all vqs and discard
all data. Add an iterator to do that.

ALSA: usb-audio: Skip broken EU on Dell dock USB-audio
commit 1d8d6428d1da642ddd75b0be2d1bb1123ff8e017 upstream.
The Dell Dock USB-audio device with 0bda:4014 is behaving notoriously
bad, and we have already applied some workaround to avoid the firmware
hiccup. Yet we still need to skip one thing, the Extension Unit at ID
4, which doesn't react correctly to the mixer ctl access.

USB: Increment wakeup count on remote wakeup.
commit 83a62c51ba7b3c0bf45150c4eac7aefc6c785e94 upstream.
On chromebooks we depend on wakeup count to identify the wakeup source.
But currently USB devices do not increment the wakeup count when they
trigger the remote wake. This patch addresses the same.
Resume condition is reported differently on USB 2.0 and USB 3.0 devices.
On USB 2.0 devices, a wake capable device, if wake enabled, drives
resume signal to indicate a remote wake (USB 2.0 spec section 7.1.7.7).
The upstream facing port then sets C_PORT_SUSPEND bit and reports a
port change event (USB 2.0 spec section 11.24.2.7.2.3). Thus if a port
has resumed before driving the resume signal from the host and
C_PORT_SUSPEND is set, then the device attached to the given port might
be the reason for the last system wakeup. Increment the wakeup count for
the same.
On USB 3.0 devices, a function may signal that it wants to exit from device
suspend by sending a Function Wake Device Notification to the host (USB3.0
spec section 8.5.6.4) Thus on receiving the Function Wake, increment the
wakeup count.

Arrow USB Blaster integrated on MAX1000 board uses the same vendor ID
(0x0403) and product ID (0x6010) as the "original" FTDI device.
This patch avoids picking up by ftdi_sio of the first interface of this

ext4: fix bitmap position validation
commit 22be37acce25d66ecf6403fc8f44df9c5ded2372 upstream.
Currently in ext4_valid_block_bitmap() we expect the bitmap to be
positioned anywhere between 0 and s_blocksize clusters, but that's
wrong because the bitmap can be placed anywhere in the block group. This
causes false positives when validating bitmaps on perfectly valid file
system layouts. Fix it by checking whether the bitmap is within the group
boundary.
The problem can be reproduced using the following
mkfs -t ext3 -E stride=256 /dev/vdb1
mount /dev/vdb1 /mnt/test
cd /mnt/test
wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.16.3.tar.xz
tar xf linux-4.16.3.tar.xz
This will result in the warnings in the logs
EXT4-fs error (device vdb1): ext4_validate_block_bitmap:399: comm tar: bg

The kernel configures the translation tables so that translations made
via TTBR0 (i.e. userspace mappings) have the top byte (bits 63:56) of
the virtual address ignored by the translation hardware. This frees up
-this byte for application use, with the following caveats:
+this byte for application use.
- (1) The kernel requires that all user addresses passed to EL1
- are tagged with tag 0x00. This means that any syscall
- parameters containing user virtual addresses *must* have
- their top byte cleared before trapping to the kernel.
- (2) Non-zero tags are not preserved when delivering signals.
- This means that signal handlers in applications making use
- of tags cannot rely on the tag information for user virtual
- addresses being maintained for fields inside siginfo_t.
- One exception to this rule is for signals raised in response
- to watchpoint debug exceptions, where the tag information
- will be preserved.
+Passing tagged addresses to the kernel
+--------------------------------------
- (3) Special care should be taken when using tagged pointers,
- since it is likely that C compilers will not hazard two
- virtual addresses differing only in the upper byte.
+All interpretation of userspace memory addresses by the kernel assumes
+an address tag of 0x00.
+
+This includes, but is not limited to, addresses found in:
+
+ - pointer arguments to system calls, including pointers in structures
+ passed to system calls,
+
+ - the stack pointer (sp), e.g. when interpreting it to deliver a
+ signal,
+
+ - the frame pointer (x29) and frame records, e.g. when interpreting
+ them to generate a backtrace or call graph.
+
+Using non-zero address tags in any of these locations may result in an
+error code being returned, a (fatal) signal being raised, or other modes
+of failure.
+
+For these reasons, passing non-zero address tags to the kernel via
+system calls is forbidden, and using a non-zero address tag for sp is
+strongly discouraged.
+
+Programs maintaining a frame pointer and frame records that use non-zero
+address tags may suffer impaired or inaccurate debug and profiling
+visibility.
+
+
+Preserving tags
+---------------
+
+Non-zero tags are not preserved when delivering signals. This means that
+signal handlers in applications making use of tags cannot rely on the
+tag information for user virtual addresses being maintained for fields
+inside siginfo_t. One exception to this rule is for signals raised in
+response to watchpoint debug exceptions, where the tag information will
+be preserved.
The architecture prevents the use of a tagged PC, so the upper byte will
be set to a sign-extension of bit 55 on exception return.
+
+
+Other considerations
+--------------------
+
+Special care should be taken when using tagged pointers, since it is
+likely that C compilers will not hazard two virtual addresses differing
+only in the upper byte.
