commit dfd8645ea1bd9127 wrongly assumes that VXLAN_VDI_MASK includes
eight lower order reserved bits of VNI field that are using for remote
checksum offload.
Right now, when VNI number greater then 0xffff, vxlan_udp_encap_recv()
will always return with 'bad_flag' error, reducing the usable vni range
from 0..16777215 to 0..65535. Also, it doesn't really check whether RCO
bits processed or not.
Fix it by adding new VNI mask which has all 32 bits of VNI field:
24 bits for id and 8 bits for other usage.

drop_fpu() does clear_used_math() and usually this is correct
because tsk == current.
However switch_fpu_finish()->restore_fpu_checking() is called before
__switch_to() updates the "current_task" variable. If it fails,
we will wrongly clear the PF_USED_MATH flag of the previous task.
So use clear_stopped_child_used_math() instead.

__restore_xstate_sig()
math_state_restore() assumes it is called with irqs disabled,
but this is not true if the caller is __restore_xstate_sig().
This means that if ia32_fxstate == T and __copy_from_user()
fails, __restore_xstate_sig() returns with irqs disabled too.
This triggers:
BUG: sleeping function called from invalid context at kernel/locking/rwsem.c:41
dump_stack
___might_sleep
? _raw_spin_unlock_irqrestore
__might_sleep
down_read
? _raw_spin_unlock_irqrestore
print_vma_addr
signal_fault
sys32_rt_sigreturn
Change __restore_xstate_sig() to call set_used_math()
unconditionally. This avoids enabling and disabling interrupts
in math_state_restore(). If copy_from_user() fails, we can
simply do fpu_finit() by hand.
[ Note: this is only the first step. math_state_restore() should
not check used_math(), it should set this flag. While
init_fpu() should simply die. ]

devm_phy_create() stores the pointer to the new PHY at the address
returned by devres_alloc(). The res parameter passed to devm_phy_match()
is therefore the location where the pointer to the PHY is stored, hence
it needs to be dereferenced before comparing to the match data in order
to find the correct match.

The kernel crypto API logic requires the caller to provide the
length of (ciphertext || authentication tag) as cryptlen for the
AEAD decryption operation. Thus, the cipher implementation must
calculate the size of the plaintext output itself and cannot simply use
cryptlen.
The RFC4106 GCM decryption operation tries to overwrite cryptlen memory
in req->dst. As the destination buffer for decryption only needs to hold
the plaintext memory but cryptlen references the input buffer holding
(ciphertext || authentication tag), the assumption of the destination
buffer length in RFC4106 GCM operation leads to a too large size. This
patch simply uses the already calculated plaintext size.
In addition, this patch fixes the offset calculation of the AAD buffer
pointer: as mentioned before, cryptlen already includes the size of the
tag. Thus, the tag does not need to be added. With the addition, the AAD
will be written beyond the already allocated buffer.
Note, this fixes a kernel crash that can be triggered from user space
via AF_ALG(aead) -- simply use the libkcapi test application
from [1] and update it to use rfc4106-gcm-aes.
Using [1], the changes were tested using CAVS vectors to demonstrate
that the crypto operation still delivers the right results.

This patch fixes the following issues regarding to the calculation of the
residue:
1. The residue is always calculated for the current transfer even if the
cookie is associated to a pending transfer.
2. For scatter/gather DMA the calculation of the residue for the current
transfer doesn't include the bytes of the child descriptors that are already
transferred.
It only calculates the difference between the transfer's total length minus
the number of bytes that are already transferred for the current child
descriptor.
For example: There is a scatter/gather DMA transfer with a total length of
1 MByte. Getting the residue several times while the transfer is running shows
something like that:
1: residue = 975584
2: residue = 1002766
3: residue = 992627
4: residue = 983767
5: residue = 985694
6: residue = 1008094
7: residue = 1009741
8: residue = 1011195
3. The driver stores the residue but never resets it when starting a new
transfer.
For example: If there are two subsequent DMA transfers. The first one with
a total length of 1 MByte and the second one with a total length of 1 kByte.
Getting the residue for both transfers shows something like that:
transfer 1: residue = 975584
transfer 2: residue = 1048380
Changes from V1:
* Fixed coding style of the multi-line comments.
* Improved accuracy of the residue calculation when the transfer for the
first descriptor is active.
Changes from V2:
* Member 'tx_width' of 'struct at_desc' restored, because the transfer width
can't be derived from the source width when using "slave_sg".
The transfer width is needed for the calculation of the residue if either
the transfer of the first or the last descriptor is in progress.
In the case of a "memory_to_memory_sg" transfer (part of this patch
series) the transfer width of both descriptors may differ. Thus it is
required to additionally set 'tx_width' of the last descriptor.
* Added functions for multiply used calculations.

The current HDA generic parser initializes / modifies the amp values
always in stereo, but this seems causing the problem on ALC3229 codec
that has a few mono channel widgets: namely, these mono widgets react
to actions for both channels equally.
In the driver code, we do care the mono channel and create a control
only for the left channel (as defined in HD-audio spec) for such a
node. When the control is updated, only the left channel value is
changed. However, in the resume, the right channel value is also
restored from the initial value we took as stereo, and this overwrites
the left channel value. This ends up being the silent output as the
right channel has been never touched and remains muted.
This patch covers the places where unconditional stereo amp accesses
are done and converts to the conditional accesses.

Eric W. Biederman says:
====================
tcp_metrics: Network namespace bloat reduction v3
This is a small pile of patches that convert tcp_metrics from using a
hash table per network namespace to using a single hash table for all
network namespaces.
This is broken up into several patches so that each small step along
the way could be carefully scrutinized as I wrote it, and equally so
that each small step can be reviewed.
There are several cleanups included in this series. The addition of
panic calls during boot where we can not handle failure, and not trying
simplifies the code. The removal of the return code from
tcp_metrics_flush_all.
The motivation for this change is that the tcp_metrics hash table at
128KiB is one of the largest components of a freshly allocated network
namespace.
I am resending the the previous version I sent has suffered bitrot, so I
have respun the patches so that they apply. I believe I have addressed
all of the review concerns except optimal behavior on little machines
with 32-byte cache lines, which is beyond me as even the current code
has bad behavior in that case.

virtio spec requires that all drivers set DRIVER_OK
before using devices. While rpmsg isn't yet
included in the virtio 1 spec, previous spec versions
also required this.
virtio rpmsg violates this rule: is calls kick
before setting DRIVER_OK.
The fix isn't trivial since simply calling virtio_device_ready earlier
would mean we might get an interrupt in parallel with adding buffers.
Instead, split kick out to prepare+notify calls. prepare before
virtio_device_ready - when we know we won't get interrupts. notify right
afterwards.

The PHY state machine (in drivers/net/phy/phy.c) will unconditionally
call phydev->adjust_link (macb_handle_link_change) when polling in the
PHY_CHANGELINK state. As currently written, macb always ends up
requesting a new tx_clk frequency in macb_handle_link_change. It is a
waste of time to request a new tx_clk frequency if the link state hasn't
changed, as the tx_clk will already be configured properly.
Let's only request a new tx_clk clock frequency when necessary.

Commit c0c09bfdc415 ("rhashtable: avoid unnecessary wakeup for worker
queue") changed ht->shift to be atomic, which is actually unnecessary.
Instead of leaving the current shift in the core rhashtable structure,
it can be cached inside the individual bucket tables.
There, it will only be initialized once during a new table allocation
in the shrink/expansion slow path, and from then onward it stays immutable
for the rest of the bucket table liftime.
That allows shift to be non-atomic. The patch also moves hash_rnd
management into the table setup. The rhashtable structure now consumes
3 instead of 4 cachelines.
