Add a generic sk_msg layer, and convert current sockmap and later
kTLS over to make use of it. While sk_buff handles network packet
representation from netdevice up to socket, sk_msg handles data
representation from application to socket layer.
This means that sk_msg framework spans across ULP users in the
kernel, and enables features such as introspection or filtering
of data with the help of BPF programs that operate on this data
structure.
Latter becomes in particular useful for kTLS where data encryption
is deferred into the kernel, and as such enabling the kernel to
perform L7 introspection and policy based on BPF for TLS connections
where the record is being encrypted after BPF has run and came to
a verdict. In order to get there, first step is to transform open
coding of scatter-gather list handling into a common core framework
that subsystems can use.
The code itself has been split and refactored into three bigger
pieces: i) the generic sk_msg API which deals with managing the
scatter gather ring, providing helpers for walking and mangling,
transferring application data from user space into it, and preparing
it for BPF pre/post-processing, ii) the plain sock map itself
where sockets can be attached to or detached from; these bits
are independent of i) which can now be used also without sock
map, and iii) the integration with plain TCP as one protocol
to be used for processing L7 application data (later this could
e.g. also be extended to other protocols like UDP). The semantics
are the same with the old sock map code and therefore no change
of user facing behavior or APIs. While pursuing this work it
also helped finding a number of bugs in the old sockmap code
that we've fixed already in earlier commits. The test_sockmap
kselftest suite passes through fine as well.
Joint work with John.

In order to prepare sockmap logic to be used in combination with kTLS
we need to detangle it from ULP, and further split it in later commits
into a generic API.

Whenever the ULP data on the socket is mangled, enforce that the
caller has the socket lock held as otherwise things may race with
initialization and cleanup callbacks from ulp ops as both would
mangle internal socket state.

The recent patch to fix the afs_server struct leak didn't actually fix the
bug, but rather fixed some of the symptoms. The problem is that an
asynchronous call that holds a resource pointed to by call->reply[0] will
find the pointer cleared in the call destructor, thereby preventing the
resource from being cleaned up.
In the case of the server record leak, the afs_fs_get_capabilities()
function in devel code sets up a call with reply[0] pointing at the server
record that should be altered when the result is obtained, but this was
being cleared before the destructor was called, so the put in the
destructor does nothing and the record is leaked.
Commit f014ffb025c1 removed the additional ref obtained by
afs_install_server(), but the removal of this ref is actually used by the
garbage collector to mark a server record as being defunct after the record
has expired through lack of use.
The offending clearance of call->reply[0] upon completion in
afs_process_async_call() has been there from the origin of the code, but
none of the asynchronous calls actually use that pointer currently, so it
should be safe to remove (note that synchronous calls don't involve this
function).
Fix this by the following means:
(1) Revert commit f014ffb025c1.
(2) Remove the clearance of reply[0] from afs_process_async_call().
Without this, afs_manage_servers() will suffer an assertion failure if it
sees a server record that didn't get used because the usage count is not 1.

In some environments it is common that many hosts share the same lower half
of their IPv6 addresses (in particular ::1). As __xfrm6_addr_hash() and
__xfrm6_daddr_saddr_hash() calculate the hash only from the lower halves,
as much as 1/3 of the hosts ends up in one hashtable chain which harms the
performance.
Use complete IPv6 addresses when calculating the hashes. Rather than just
adding two more words to the xor, use jhash2() for consistency with
__xfrm6_pref_hash() and __xfrm6_dpref_spref_hash().

If we did some signal processing, we have to reload the pt_regs
tstate register because it's value may have changed.
In doing so we also have to extract the %pil value contained in there
anre load that into %l4.
This value is at bit 20 and thus needs to be shifted down before we
later write it into the %pil register.
Most of the time this is harmless as we are returning to userspace
and the %pil is zero for that case.

ath10k_pci_diag_write_mem may allocate big size of the dma memory
based on the parameter nbytes. Take firmware diag download as
example, the biggest size is about 500K. In some systems, the
allocation is likely to fail because it can't acquire such a large
contiguous dma memory.
The fix is to allocate a small size dma memory. In the loop,
driver copies the data to the allocated dma memory and writes to
the destination until all the data is written.

cause unexpected behavior since the firmware is
already down and the wmi has been detached.
Send the wmi command for setting probe request
oui during the driver start. This will make sure
that the firmware is started and wmi is initialized
before we send this command.

While using 'ath10k_mac_get_rate_hw_value()' to obtain the hw value
from the passed bitrate, there is a chance of out of bound array access
when wrong bitrate is passed. This is fixed by comparing the bitrates
within the correct size of the ath10k_rates array.
Fixes commit f279294e9ee2 ("ath10k: add support for configuring management
packet rate"). Also correction made to some indents used in the above commit.

This makes the error handling somewhat cleaner -- lbs_add_card() does no
logner throw away the errno and lets its callers propagate it.

The variables il->staging.filter_flags, rxon1->filter_flags and
rxon2->filter_flags need to be protected by the mutex lock il->mutex.
This patch adds a lock assertion of il->mutex to check whether
this lock is held.

Beacons are not updated to reflect TIM changes. This is not compliant with
power-saving client stations as the beacons do not have valid TIM and can
cause the network to stall at random occasions and to have highly variable
latencies.
Fix it by updating beacon templates on mac80211 set_tim callback.
