Handle PPPIOCGL2TPSTATS in pppol2tp_ioctl() if the socket represents a
tunnel. This one is a bit special because the caller may use the tunnel
socket to retrieve statistics of one of its sessions. If the session_id
is set, the corresponding session's statistics are returned, instead of
those of
* Drop test on 'sk': sock->sk cannot be NULL, or pppox_ioctl() could
not have called us.
* Drop test on 'SOCK_DEAD' state: if this flag was set, the socket
would be in the process of being released and no ioctl could be
running anymore.
* Drop test on 'PPPOX_*' state: we depend
Return -ENOIOCTLCMD for unknown ioctl commands. This lets dev_ioctl()
handle generic socket ioctls like SIOCGIFNAME or SIOCGIFINDEX.
PF_PPPOX/PX_PROTO_OL2TP was one of the few socket types not honouring
this mechanism.

Use helper function to figure out if a tunnel is using ipsec.
Also, avoid accessing ->sk_policy directly since it's RCU protected.

The current ioctl() handling code can be simplified. It tests for
non-relevant conditions and uselessly holds sockets. Once useless
code is removed, it becomes even simpler to let pppol2tp_ioctl() handle
commands directly, rather than dispatch them to pppol2tp_tunnel_ioctl()
or
Integrate memset(0) in pppol2tp_copy_stats() to avoid calling it
manually every time.
While there, constify 'stats'.

l2tp_session_get() is used for two different purposes. If 'tunnel' is
NULL, the session is searched globally in the supplied network
namespace. Otherwise it is searched exclusively in the tunnel context.
Callers always know the context in which they need to search the
session. But some of them do
pppol2tp_ioctl() has everything in place for handling PPPIOCGL2TPSTATS
on session sockets. We just need to copy the stats and set ->session_id.
As a side effect of sharing session and tunnel code, ->using_ipsec is
properly set even when the request was made using a session socket.

Let pppol2tp_ioctl() handle ioctl commands directly. It still relies on
pppol2tp_{session,tunnel}_ioctl() for PPPIOCGL2TPSTATS.

Use modern kvzalloc()/kvfree() instead of custom allocations.
And remove order argument for free_pg_vec and alloc_pg_vec,
this argument is useless to kvfree, or can get from req.

For preparing decryption request, several memory chunks are required
(aead_req, sgin, sgout, iv, aad). For submitting the decrypt request to
an accelerator, it is required that the buffers which are read by the
accelerator must be dma-able and not come from stack. The buffers for
aad and iv can be
This patch does a combined memory allocation from heap for scatterlists,

This reverts commit 36e0f12bbfd3016f495904b35e41c5711707509f.
The reverted commit adds a WARN to check against NULL entries in the

MMIO reads for remaining packets in queue occur (at least)twice per
invocation of netsec_process_rx(). We can use the packet descriptor to
identify if it's owned by the hardware and break out, avoiding the more
expensive MMIO read operations. This has a ~2% increase on the pps of the
Rx path when
