commit c6cdd51404b7ac12dd95173ddfc548c59ecf037f upstream.
Marios Titas running a Haskell program noticed a problem with fuse's
readdirplus: when it is interrupted by a signal, it skips one directory
entry.
The reason is that fuse erronously updates ctx->pos after a failed
dir_emit().
The issue originates from the patch adding readdirplus support.

commit b3207c65dfafae27e7c492cb9188c0dc0eeaf3fd upstream.
xhci_stop_device() calls xhci_queue_stop_endpoint() multiple times
without checking the return value. xhci_queue_stop_endpoint() can
return error if the HC is already halted or unable to queue commands.
This can cause a deadlock condition as xhci_stop_device() would
end up waiting indefinitely for a completion for the command that
didn't get queued. Fix this by checking the return value and bailing
out of xhci_stop_device() in case of error. This patch happens to fix
potential memory leaks of the allocated command structures as well.

, which will cause a irq inversion deadlock if the above lock scenario
happens.
The root cause of this safe -> unsafe lock order is the
mutex_unlock(pool->manager_arb) in manage_workers() with pool->lock
held.
Unlocking mutex while holding an irq spinlock was never safe and this
problem has been around forever but it never got noticed because the
only time the mutex is usually trylocked while holding irqlock making
actual failures very unlikely and lockdep annotation missed the
condition until the recent b9c16a0e1f73 ("locking/mutex: Fix
lockdep_assert_held() fail").
Using mutex for pool->manager_arb has always been a bit of stretch.
It primarily is an mechanism to arbitrate managership between workers
which can easily be done with a pool flag. The only reason it became
a mutex is that pool destruction path wants to exclude parallel
managing operations.
This patch replaces the mutex with a new pool flag POOL_MANAGER_ACTIVE
and make the destruction path wait for the current manager on a wait
queue.
v2: Drop unnecessary flag clearing before pool destruction as
suggested by Boqun.

When the file /proc/fs/fscache/objects (available with
CONFIG_FSCACHE_OBJECT_LIST=y) is opened, we request a user key with
description "fscache:objlist", then access its payload. However, a
revoked key has a NULL payload, and we failed to check for this.
request_key() *does* skip revoked keys, but there is still a window
where the key can be revoked before we access its payload.
Fix it by checking for a NULL payload, treating it like a key which was
already revoked at the time it was requested.

[Please apply to 4.4-stable. Note: this was already backported, but
only to ext4; it was missed that it should go to f2fs as well. This is
needed to make xfstest generic/395 pass on f2fs.]
Since setting an encryption policy requires writing metadata to the
filesystem, it should be guarded by mnt_want_write/mnt_drop_write.
Otherwise, a user could cause a write to a frozen or readonly
filesystem. This was handled correctly by f2fs but not by ext4. Make
fscrypt_process_policy() handle it rather than relying on the filesystem
to get it right.

commit 363b02dab09b3226f3bd1420dad9c72b79a42a76 upstream.
Consolidate KEY_FLAG_INSTANTIATED, KEY_FLAG_NEGATIVE and the rejection
error into one field such that:
(1) The instantiation state can be modified/read atomically.
(2) The error can be accessed atomically with the state.
(3) The error isn't stored unioned with the payload pointers.
This deals with the problem that the state is spread over three different
objects (two bits and a separate variable) and reading or updating them
atomically isn't practical, given that not only can uninstantiated keys
change into instantiated or rejected keys, but rejected keys can also turn
into instantiated keys - and someone accessing the key might not be using
any locking.
The main side effect of this problem is that what was held in the payload
may change, depending on the state. For instance, you might observe the
key to be in the rejected state. You then read the cached error, but if
the key semaphore wasn't locked, the key might've become instantiated
between the two reads - and you might now have something in hand that isn't
actually an error code.
The state is now KEY_IS_UNINSTANTIATED, KEY_IS_POSITIVE or a negative error
code if the key is negatively instantiated. The key_is_instantiated()
function is replaced with key_is_positive() to avoid confusion as negative
keys are also 'instantiated'.
Additionally, barriering is included:
(1) Order payload-set before state-set during instantiation.
(2) Order state-read before payload-read when using the key.
Further separate barriering is necessary if RCU is being used to access the
payload content after reading the payload pointers.

commit 18f649ef344127ef6de23a5a4272dbe2fdb73dde upstream.
The PF_EXITING check in task_wants_autogroup() is no longer needed. Remove
it, but see the next patch.
However the comment is correct in that autogroup_move_group() must always
change task_group() for every thread so the sysctl_ check is very wrong;
we can race with cgroups and even sys_setsid() is not safe because a task
running with task_group() == ag->tg must participate in refcounting:
int main(void)
{
int sctl = open("/proc/sys/kernel/sched_autogroup_enabled", O_WRONLY);
assert(sctl > 0);
if (fork()) {
wait(NULL); // destroy the child's ag/tg
pause();
}
assert(pwrite(sctl, "1\n", 2, 0) == 2);
assert(setsid() > 0);
if (fork())
pause();
kill(getppid(), SIGKILL);
sleep(1);
// The child has gone, the grandchild runs with kref == 1
assert(pwrite(sctl, "0\n", 2, 0) == 2);
assert(setsid() > 0);
// runs with the freed ag/tg
for (;;)
sleep(1);
return 0;
}
crashes the kernel. It doesn't really need sleep(1), it doesn't matter if
autogroup_move_group() actually frees the task_group or this happens later.

As discussed on the debian-hppa list, double-wordcompare and exchange
operations fail on 32-bit kernels. Looking at the code, I realized that
the ",ma" completer does the wrong thing in the "ldw,ma 4(%r26), %r29"
instruction. This increments %r26 and causes the following store to
write to the wrong location.

commit 60ff5b2f547af3828aebafd54daded44cfb0807a upstream.
Currently, when passed a key that already exists, add_key() will call the
key's ->update() method if such exists. But this is heavily broken in the
case where the key is uninstantiated because it doesn't call
__key_instantiate_and_link(). Consequently, it doesn't do most of the
things that are supposed to happen when the key is instantiated, such as
setting the instantiation state, clearing KEY_FLAG_USER_CONSTRUCT and
awakening tasks waiting on it, and incrementing key->user->nikeys.
It also never takes key_construction_mutex, which means that
->instantiate() can run concurrently with ->update() on the same key. In
the case of the "user" and "logon" key types this causes a memory leak, at
best. Maybe even worse, the ->update() methods of the "encrypted" and
"trusted" key types actually just dereference a NULL pointer when passed an
uninstantiated key.
Change key_create_or_update() to wait interruptibly for the key to finish
construction before continuing.
This patch only affects *uninstantiated* keys. For now we still allow a
negatively instantiated key to be updated (thereby positively
instantiating it), although that's broken too (the next patch fixes it)
and I'm not sure that anyone actually uses that functionality either.
Here is a simple reproducer for the bug using the "encrypted" key type
(requires CONFIG_ENCRYPTED_KEYS=y), though as noted above the bug
pertained to more than just the "encrypted" key type:
#include <stdlib.h>
#include <unistd.h>
#include <keyutils.h>
int main(void)
{
int ringid = keyctl_join_session_keyring(NULL);
if (fork()) {
for (;;) {
const char payload[] = "update user:foo 32";
usleep(rand() % 10000);
add_key("encrypted", "desc", payload, sizeof(payload), ringid);
keyctl_clear(ringid);
}
} else {
for (;;)
request_key("encrypted", "desc", "callout_info", ringid);
}
}
It causes:

commit eb39a7c0355393c5a8d930f342ad7a6231b552c4 upstream.
The interrupt handler mfgpt_tick() is not robust versus spurious interrupts
which happen before the clock event device is registered and fully
initialized.
The reason is that the safe guard against spurious interrupts solely checks
for the clockevents shutdown state, but lacks a check for detached
state. If the interrupt hits while the device is in detached state it
passes the safe guard and dereferences the event handler call back which is
NULL.
Add the missing state check.

commit 2bbbd96357ce76cc45ec722c00f654aa7b189112 upstream.
At least the Armada XP SoC supports 4GB on a single DRAM window. Because
the size register values contain the actual size - 1, the MSB is set in
that case. For example, the SDRAM window's control register's value is
0xffffffe1 for 4GB (bits 31 to 24 contain the size).
The MBUS driver reads back each window's size from registers and
calculates the actual size as (control_reg | ~DDR_SIZE_MASK) + 1, which
overflows for 32 bit values, resulting in other miscalculations further
on (a bad RAM window for the CESA crypto engine calculated by
mvebu_mbus_setup_cpu_target_nooverlap() in my case).
This patch changes the type in 'struct mbus_dram_window' from u32 to
u64, which allows us to keep using the same register calculation code in
most MBUS-using drivers (which calculate ->size - 1 again).

commit c503dd38f850be28867ef7a42d9abe5ade81a9bd upstream.
With KASAN and a couple of other patches applied, this driver is one
of the few remaining ones that actually use more than 2048 bytes of
kernel stack:
broadcom/brcm80211/brcmsmac/phy/phy_n.c: In function 'wlc_phy_workarounds_nphy_gainctrl':
broadcom/brcm80211/brcmsmac/phy/phy_n.c:16065:1: warning: the frame size of 3264 bytes is larger than 2048 bytes [-Wframe-larger-than=]

broadcom/brcm80211/brcmsmac/phy/phy_n.c:17138:1: warning: the frame size of 2864 bytes is larger than 2048 bytes [-Wframe-larger-than=]
Here, I'm reducing the stack size by marking as many local variables as
'static const' as I can without changing the actual code.
This is the first of three patches to improve the stack usage in this
driver. It would be good to have this backported to stabl kernels
to get all drivers in 'allmodconfig' below the 2048 byte limit so
we can turn on the frame warning again globally, but I realize that
the patch is larger than the normal limit for stable backports.
The other two patches do not need to be backported.

Commit b6c159a9cb69 ("i2c: ismt: Don't duplicate the receive length for
block reads") broke I2C block reads. It aimed to fix normal SMBus block
read, but changed the correct behavior of I2C block read in the process.
According to Documentation/i2c/smbus-protocol, one vital difference
between normal SMBus block read and I2C block read is that there is no
byte count prefixed in the data sent on the wire:
SMBus Block Read: i2c_smbus_read_block_data()
S Addr Wr [A] Comm [A]
S Addr Rd [A] [Count] A [Data] A [Data] A ... A [Data] NA P
I2C Block Read: i2c_smbus_read_i2c_block_data()
S Addr Wr [A] Comm [A]
S Addr Rd [A] [Data] A [Data] A ... A [Data] NA P
Therefore the two transaction types need to be processed differently in
the driver by copying of the dma_buffer as done previously for the
I2C_SMBUS_I2C_BLOCK_DATA case.

commit 445ef61543da3db5b699f87fb0aa4f227165f6ed upstream.
The sunxi musb has a bug where sometimes it will generate a babble
error on device disconnect instead of a disconnect IRQ. When this
happens the musb controller switches from host mode to device mode
(it clears MUSB_DEVCTL_HM/MUSB_DEVCTL_SESSION and sets
MUSB_DEVCTL_BDEVICE) and gets stuck in this state.
The babble error is misdetected as a bus reset because MUSB_DEVCTL_HM
was cleared.
To fix this, use is_host_active() rather than (devctl & MUSB_DEVCTL_HM)
to detect babble error so that sunxi musb babble recovery can handle it
by restoring the mode. This information is provided by the driver logic
and does not rely on register contents.

If sending messages with no cable connected, it quickly happens that

returns with "NETDEV_TX_BUSY" and the upper layer does retry
immediately keeping the CPU busy. To fix that issue, I moved
"atomic_dec(&dev->active_tx_urbs)" from "gs_usb_xmit_callback()" to
the TX done handling in "gs_usb_receive_bulk_callback()". Renaming
"active_tx_urbs" to "active_tx_contexts" and moving it into
"gs_[alloc|free]_tx_context()" would also make sense.

If the connect status change is set during reset signaling, but
the status remains connected just retry port reset.
This solves an issue with connecting a 90W HP Thunderbolt 3 dock
with a Lenovo Carbon x1 (5th generation) which causes a 30min loop
of a high speed device being re-discovererd before usb ports starts
working.
[...]

[ 389.959928] usb 3-1: new high-speed USB device number 57 using xhci_hcd
[...]
This is caused by a high speed device that doesn't successfully go to the
enabled state after the second port reset. Instead the connection bounces
(connected, with connect status change), bailing out completely from
enumeration just to restart from scratch.

commit 845d584f41eac3475c21e4a7d5e88d0f6e410cf7 upstream.
Taking the uurb->buffer_length userspace passes in as a maximum for the
actual urbs transfer_buffer_length causes 2 serious issues:
1) It breaks isochronous support for all userspace apps using libusb,
as existing libusb versions pass in 0 for uurb->buffer_length,
relying on the kernel using the lenghts of the usbdevfs_iso_packet_desc
descriptors passed in added together as buffer length.
This for example causes redirection of USB audio and Webcam's into
virtual machines using qemu-kvm to no longer work. This is a userspace
ABI break and as such must be reverted.
Note that the original commit does not protect other users / the
kernels memory, it only stops the userspace process making the call
from shooting itself in the foot.
2) It may cause the kernel to program host controllers to DMA over random
memory. Just as the devio code used to only look at the iso_packet_desc
lenghts, the host drivers do the same, relying on the submitter of the
urbs to make sure the entire buffer is large enough and not checking
transfer_buffer_length.
But the "USB: devio: Don't corrupt user memory" commit now takes the
userspace provided uurb->buffer_length for the buffer-size while copying
over the user-provided iso_packet_desc lengths 1:1, allowing the user
to specify a small buffer size while programming the host controller to
dma a lot more data.
(Atleast the ohci, uhci, xhci and fhci drivers do not check
transfer_buffer_length for isoc transfers.)
This reverts commit fa1ed74eb1c2 ("USB: devio: Don't corrupt user memory")
fixing both these issues.

[ Upstream commit c6b0b656ca24ede6657abb4a2cd910fa9c1879ba ]
While we hold a reference to the dentry when build_dentry_path is
called, we could end up racing with a rename that changes d_parent.
Handle that situation correctly, by using the rcu_read_lock to
ensure that the parent dentry and inode stick around long enough
to safely check ceph_snap and ceph_ino.

When going to suspend, the I2C registers may be lost because the power to
VDDcore is cut. Restore them when resuming.
