Assert and deassert functionality of the DSP found on i.MX8MP is

OpenVPN is a userspace software existing since around 2005 that allows
users to create secure tunnels.
So far OpenVPN has implemented all operations in userspace, which
implies several back and forth between kernel and user land in order to
process packets (encapsulate/decapsulate, encrypt/decrypt
Notable changes since v21:
* accessed crypto_slot->primary_idx via READ/WRITE_ONCE
* made ovpn_aead_init() static
* converted link tx/rx packet counters from u32 to to uint
* ensured all u32 NL attributes are read by nla_get_u32()
* ensured all u32 NL attrivutes are written by nla_put_u32()
* reset
This specific structure is used in the ovpn kernel module
to wrap and carry around a standard kernel socket.
ovpn takes ownership of passed sockets and therefore an ovpn

purposes.

With this change ovpn is allowed to communicate to peers also via TCP.
Parsing of incoming messages is implemented through the strparser API.
Note that ovpn redefines sk_prot and sk_socket->ops for the TCP socket
used to communicate with the peer.
For this reason it needs to access inet6_stream_op
When sending an skb over a socket using skb_send_sock_locked(),
it is currently not possible to specify any flag to be set in

Whenever a peer is deleted, send a notification to userspace so that it
can react accordingly.
This is most important when a peer is deleted due to ping timeout,
because it all happens in kernelspace and thus userspace has no direct

Set the MMC_CAP_NEED_RSP_BUSY capability for the sdhci-pxav3 host to
prevent conversion of R1B responses to R1. Without this, the eMMC card
in the samsung,coreprimevelte smartphone using the Marvell PXA1908 SoC
with this mmc host doesn't probe with the ETIMEDOUT error originating in
__mmc_poll_for_
Minor cleanup, this is a non-functional change.

Adding the aligned(1024) attribute to the definition of __rseq_abi did
not increase its size to 1024, for this attribute to impact the size of
__rseq_abi it would need to be added to the declaration of 'struct
rseq_abi'. We only want to increase the size of the TLS allocation to
ensure registration

Move the logic to mark special sections as read-only after module
initialization into a separate function, along other related code in
strict_rwx.c. Use a table with names of such sections to make it easier to
add more.
