The main part is the patch 2 that converts the driver to GPIO descriptor APIs,
the first one is just an ad-hoc fix WRT sparse complains on the bitwise

Similar to syscall_set_arguments() that complements
syscall_get_arguments(), introduce syscall_set_nr()
that complements syscall_get_nr().
syscall_set_nr() is going to be needed along with

Not true, see below.
This series is built on top of the v3 write syscall support [1].
With James's KVM userfault [2], it is possible to handle stage-2 faults
in guest_memfd in userspace. However, KVM itself also triggers faults
in guest_memfd in some cases, for example: PV interfaces like kvmclock,

In a multi-peer scenario there are a number of situations when a
specific peer needs to be looked up.
We may want to lookup a peer by:
1. its ID
2. its VPN destination IP
3. its transport IP/port couple
For each of the above, there is a specific routing table referencing all
peers for fast look u
The ovpn-cli tool can be compiled and used as selftest for the ovpn
kernel module.
[NOTE: it depends on libmedtls for decoding base64-encoded keys]
ovpn-cli implements the netlink and RTNL APIs and can thus be integrated
in any script for more automated testing.
Along with the tool, a bunch of s
A peer connected via UDP may change its IP address without reconnecting
(float).
Add support for detecting and updating the new peer IP/port in case of
floating.

Implement support for basic ethtool functionality.
Note that ovpn is a virtual device driver, therefore
various ethtool APIs are just not meaningful and thus
not implemented.

This change introduces the netlink commands needed to add, get, delete
and swap keys for a specific peer.
Userspace is expected to use these commands to create, inspect (non
sensitive data only), destroy and rotate session keys for a specific
peer.

This specific structure is used in the ovpn kernel module
to wrap and carry around a standard kernel socket.

Userspace has two ways of deciding when the key has to be renewed before

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
way to learn about it.

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
Byte/packet counters for in-tunnel and transport streams
are now initialized and updated as needed.

This series adds a fix for KVM PMU code and improves the pmu selftest
by allowing generating precise number of interrupts. It also provided
another additional option to the overflow test that allows user to

Changes in v2:
There is no need to start the counter in the overflow handler as we
intend to trigger precise number of LCOFI interrupts through these
tests. The overflow irq handler has already stopped the counter. As
a result, the stop call from the test function may return already

This commit introduces basic netlink support with family
registration/unregistration functionalities and stub pre/post-doit.
More importantly it introduces the YAML uAPI description along
with its auto-generated files:
- include/uapi/linux/ovpn.h
- drivers/net/ovpn/netlink-gen.c
- drivers/net/ovpn
Add basic infrastructure for handling ovpn interfaces.

An ovpn interface configured in MP mode will keep carrier always
on and let the user decide when to bring it administratively up and
down.
This way a MP node (i.e. a server) will keep its interface always
up and running, even when no peer is connected.

Notable changes since v20:
* removed newline at the end of message in NL_SET_ERR_MSG_FMT_MOD
* dropped udp_init() and related build_protos() and directly use
.encap_destroy [instead of overriding sk->close()]

OpenVPN is a userspace software existing since around 2005 that allows
users to create secure tunnels.

An ovpn_peer object holds the whole status of a remote peer

This includes status for crypto, tx/rx buffers, napi, etc.

Multi peer support is introduced with a later patch.
