Subsequent patches will add an offload / trap indication to routes which
will signal if the route is present in hardware or not.
After programming the route to the hardware, drivers will have to ask
the IPv4 code to set the flags by passing the route's key.
In the case of route replace, the new route is notified before it is
actually inserted into the FIB alias list. This can prevent simple
drivers (e.g., netdevsim) that program the route to the hardware in the
same context it is notified in from being able to set the flag.
Solve this by first inserting the new route to the list and rollback the
operation in case the route was vetoed.

QRTR flow control improvements
In order to prevent overconsumption of resources on the remote side QRTR
implements a flow control mechanism.
Move the handling of the incoming confirm_rx to the receiving process to
ensure incoming flow is controlled. Then implement outgoing flow
control, using the recommended algorithm of counting outstanding
non-confirmed messages and blocking when hitting a limit. The last three
patches refactors the node assignment and port lookup, in order to
remove the worker in the receive path.

Rather than enqueuing messages and scheduling a worker to deliver them
to the individual sockets we can now, thanks to the previous work, move
this directly into the endpoint callback.
This saves us a context switch per incoming message and removes the
possibility of an opportunistic suspend to happen between the message is
coming from the endpoint until it ends up in the socket's receive
buffer.

The important part of qrtr_port_lookup() wrt synchronization is that the
function returns a reference counted struct qrtr_sock, or fail.
As such we need only to ensure that an decrement of the object's
refcount happens inbetween the finding of the object in the idr and
qrtr_port_lookup()'s own increment of the object.
By using RCU and putting a synchronization point after we remove the
mapping from the idr, but before it can be released we achieve this -
with the benefit of not having to hold the mutex in qrtr_port_lookup().

In order to prevent overconsumption of resources on the remote side QRTR
implements a flow control mechanism.
The mechanism works by the sender keeping track of the number of
outstanding unconfirmed messages that has been transmitted to a
particular node/port pair.
Upon count reaching a low watermark (L) the confirm_rx bit is set in the
outgoing message and when the count reaching a high watermark (H)
transmission will be blocked upon the reception of a resume_tx message
from the remote, that resets the counter to 0.
This guarantees that there will be at most 2H - L messages in flight.
Values chosen for L and H are 5 and 10 respectively.

This is a conversion case for the new function, keeping the flow of the

skb_mark_not_on_list instead of a null write to skb->next.
Finally, this code appeared to have a memory leak in the case where
header building fails before the last gso segment. In that case, the
remaining segments are not freed. So this commit also adds the proper
kfree_skb_list call for the remainder of the skbs.

====================
net: macsec: initial support for hardware offloading
This series intends to add support for offloading MACsec transformations
to hardware enabled devices. The series adds the necessary
infrastructure for offloading MACsec configurations to hardware drivers,
in patches 1 to 5; then introduces MACsec offloading support in the
Microsemi MSCC PHY driver, in patches 6 to 10.
The series can also be found at:
https://github.com/atenart/linux/tree/net-next/macsec
IProute2 modifications can be found at:
https://github.com/atenart/iproute2/tree/macsec
MACsec hardware offloading infrastructure
-----------------------------------------
Linux has a software implementation of the MACsec standard. There are
hardware engines supporting MACsec operations, such as the Intel ixgbe
NIC and some Microsemi PHYs (the one we use in this series). This means
the MACsec offloading infrastructure should support networking PHY and
MAC drivers. Note that MAC driver preliminary support is part of this
series, but should not be merged before we actually have a provider for
this.
We do intend in this series to re-use the logic, netlink API and data
structures of the existing MACsec software implementation. This allows
not to duplicate definitions and structure storing the same information;
as well as using the same userspace tools to configure both software or
hardware offloaded MACsec flows (with `ip macsec`).
When adding a new MACsec virtual interface the existing logic is kept:
offloading is disabled by default. A user driven configuration choice is
needed to switch to offloading mode (a patch in iproute2 is needed for
this). A single MACsec interface can be offloaded for now, and some
limitations are there: no flow can be moved from one implementation to
the other so the decision needs to be done before configuring the
interface.
MACsec offloading ops are called in 2 steps: a preparation one, and a
commit one. The first step is allowed to fail and should be used to
check if a provided configuration is compatible with a given MACsec
capable hardware. The second step is not allowed to fail and should
only be used to enable a given MACsec configuration.
A limitation as of now is the counters and statistics are not reported
back from the hardware to the software MACsec implementation. This
isn't an issue when using offloaded MACsec transformations, but it
should be added in the future so that the MACsec state can be reported
to the user (which would also improve the debug).
Microsemi PHY MACsec support
----------------------------
In order to add support for the MACsec offloading feature in the
Microsemi MSCC PHY driver, the __phy_read_page and __phy_write_page
helpers had to be exported. This is because the initialization of the
PHY is done while holding the MDIO bus lock, and we need to change the
page to configure the MACsec block.
The support itself is then added in three patches. The first one adds
support for configuring the MACsec block within the PHY, so that it is
up, running and available for future configuration, but is not doing any
modification on the traffic passing through the PHY. The second patch
implements the phy_device MACsec ops in the Microsemi MSCC PHY driver,
and introduce helpers to configure MACsec transformations and flows to
match specific packets. The last one adds support for PN rollover.
Thanks!
Antoine
Since v5:
- Fixed a compilation issue due to an inclusion from an UAPI header.
- Added an EXPORT_SYMBOL_GPL for the PN rollover helper, to fix module
compilation issues.
- Added a dependency for the MSCC driver on MACSEC || MACSEC=n.
- Removed the patches including the MAC offloading support as they are
not to be applied for now.
Since v4:
- Reworked the MACsec read and write functions in the MSCC PHY driver
to remove the conditional locking.
Since v3:
- Fixed a check when enabling offloading that was too restrictive.
- Fixed the propagation of the changelink event to the underlying
device drivers.
Since v2:
- Allow selection the offloading from userspace, defaulting to the
software implementation when adding a new MACsec interface. The
offloading mode is now also reported through netlink.
- Added support for letting MKA packets in and out when using MACsec
(there are rules to let them bypass the MACsec h/w engine within the
PHY).
- Added support for PN rollover (following what's currently done in
the software implementation: the flow is disabled).
- Split patches to remove MAC offloading support for now, as there are
no current provider for this (patches are still included).
- Improved a few parts of the MACsec support within the MSCC PHY
driver (e.g. default rules now block non-MACsec traffic, depending
on the configuration).
- Many cosmetic fixes & small improvements.
Since v1:
- Reworked the MACsec offloading API, moving from a single helper
called for all MACsec configuration operations, to a per-operation
function that is provided by the underlying hardware drivers.
- Those functions now contain a verb to describe the configuration
action they're offloading.
- Improved the error handling in the MACsec genl helpers to revert
the configuration to its previous state when the offloading call
failed.
- Reworked the file inclusions.

This patch adds support for initializing the MACsec engine found within
some Microsemi PHYs. The engine is initialized in a passthrough mode and
does not modify any incoming or outgoing packet. But thanks to this it
now can be configured to perform MACsec transformations on packets,
which will be supported by a future patch.
The MACsec read and write functions are wrapped into two versions: one
called during the init phase, and the other one later on. This is
because the init functions in the Microsemi PHY driver are called while
the MDIO bus lock is taken.

MACsec offloading to underlying hardware devices is disabled by default
(the software implementation is used). This patch adds support for
changing this setting through the MACsec netlink interface. Many checks
are done when enabling offloading on a given MACsec interface as there
are limitations (it must be supported by the hardware, only a single
interface can be offloaded on a given physical device at a time, rules
can't be moved for now).

This patch introduces the MACsec hardware offloading infrastructure.
The main idea here is to re-use the logic and data structures of the
software MACsec implementation. This allows not to duplicate definitions
and structure storing the same kind of information. It also allows to
use a unified genlink interface for both MACsec implementations (so that
the same userspace tool, `ip macsec`, is used with the same arguments).
The MACsec offloading support cannot be disabled if an interface
supports it at the moment.
The MACsec configuration is passed to device drivers supporting it
through macsec_ops which are called from the MACsec genl helpers. Those
functions call the macsec ops of PHY and Ethernet drivers in two steps:
a preparation one, and a commit one. The first step is allowed to fail
and should be used to check if a provided configuration is compatible
with the features provided by a MACsec engine, while the second step is
not allowed to fail and should only be used to enable a given MACsec
configuration. Two extra calls are made: when a virtual MACsec interface
is created and when it is deleted, so that the hardware driver can stay
in sync.
The Rx and TX handlers are modified to take in account the special case
were the MACsec transformation happens in the hardware, whether in a PHY
or in a MAC, as the packets seen by the networking stack on both the
physical and MACsec virtual interface are exactly the same. This leads
to some limitations: the hardware and software implementations can't be
used on the same physical interface, as the policies would be impossible
to fulfill (such as strict validation of the frames). Also only a single
virtual MACsec interface can be offloaded to a physical port supporting
hardware offloading as it would be impossible to guess onto which
interface a given packet should go (for ingress traffic).
Another limitation as of now is that the counters and statistics are not
reported back from the hardware to the software MACsec implementation.
This isn't an issue when using offloaded MACsec transformations, but it
should be added in the future so that the MACsec state can be reported
to the user (which would also improve the debug).

When peernet2id() had to lock "nsid_lock" before iterating through the
nsid table, we had to disable BHs, because VXLAN can call peernet2id()
from the xmit path:
vxlan_xmit() -> vxlan_fdb_miss() -> vxlan_fdb_notify()
-> __vxlan_fdb_notify() -> vxlan_fdb_info() -> peernet2id().
Now that peernet2id() uses RCU protection, "nsid_lock" isn't used in BH
context anymore. Therefore, we can safely use plain
spin_lock()/spin_unlock() and let BHs run when holding "nsid_lock".

__peernet2id() can be protected by RCU as it only calls idr_for_each(),
which is RCU-safe, and never modifies the nsid table.
rtnl_net_dumpid() can also do lockless lookups. It does two nested
idr_for_each() calls on nsid tables (one direct call and one indirect
call because of rtnl_net_dumpid_one() calling __peernet2id()). The
netnsid tables are never updated. Therefore it is safe to not take the
nsid_lock and run within an RCU-critical section instead.

__peernet2id_alloc() was used for both plain lookups and for netns ID
allocations (depending the value of '*alloc'). Let's separate lookups
from allocations instead. That is, integrate the lookup code into
__peernet2id() and make peernet2id_alloc() responsible for allocating
new netns IDs when necessary.
This makes it clear that __peernet2id() doesn't modify the idr and
prepares the code for lockless lookups.
Also, mark the 'net' argument of __peernet2id() as 'const', since we're
modifying this line.
