Commit 13a56b44 ("at803x: Add support for hardware reset") added a
work-around for a hardware bug on the AT8030. However, the work-around
was being called for all 803x PHYs, even those that don't need it.
Function at803x_link_change_notify() checks to make sure that it only
resets the PHY on the 8030, but it makes more sense to not call that
function at all if it isn't needed.

Fix casting in net_gso_ok. Otherwise the shift on
gso_type << NETIF_F_GSO_SHIFT may hit the 32th bit and make it look like
a INT_MIN, which is then promoted from signed to uint64 which is
0xffffffff80000000, resulting in wrong behavior when it is and'ed with
the feature itself, as in:
This test app:
#include <stdio.h>
#include <stdint.h>
int main(int argc, char **argv)
{
uint64_t feature1;
uint64_t feature2;
int gso_type = 1 << 15;
feature1 = gso_type << 16;
feature2 = (uint64_t)gso_type << 16;
printf("%lx %lx\n", feature1, feature2);
return 0;
}
Gives:
ffffffff80000000 80000000
So that this:
return (features & feature) == feature;
Actually works on more bits than expected and invalid ones.
Fix is to promote it earlier.

When certain firmware variants are selected (via the sfboot utility) the
SFC7000 and SFC8000 series NICs don't support RSS. The driver still
tries (and fails) to insert filters with the RSS flag, and the NIC fails
to pass traffic.
When the firmware reports RSS_LIMITED suppress allocating a default RSS
context. The absence of an RSS context is picked up in filter insertion
and RSS flags are discarded.

If PAGE_SIZE is bigger than BNXT_RX_PAGE_SIZE, that means the native CPU
page is bigger than the maximum length of the RX BD. Divide the page
into multiple 32K buffers for the aggregation ring.
Add an offset field in the bnxt_sw_rx_agg_bd struct to keep track of the
page offset of each buffer. Since each page can be referenced by multiple
buffer entries, call get_page() as needed to get the proper reference
count.

The RX BD length field of this device is 16-bit, so the largest buffer
size is 65535. For LRO and GRO, we allocate native CPU pages for the
aggregation ring buffers. It won't work if the native CPU page size is
64K or bigger.
We fix this by defining BNXT_RX_PAGE_SIZE to be native CPU page size
up to 32K. Replace PAGE_SIZE with BNXT_RX_PAGE_SIZE in all appropriate
places related to the rx aggregation ring logic.
The next patch will add additional logic to divide the page into 32K
chunks for aggrgation ring buffers if PAGE_SIZE is bigger than
BNXT_RX_PAGE_SIZE.

This is more prep-work for the upcoming pty changes. Still just code
cleanup with no actual semantic changes.
This removes a bunch pointless complexity by just having the slave pty
side remember the dentry associated with the devpts slave rather than
the inode. That allows us to remove all the "look up the dentry" code
for when we want to remove it again.
Together with moving the tty pointer from "inode->i_private" to
"dentry->d_fsdata" and getting rid of pointless inode locking, this
removes about 30 lines of code. Not only is the end result smaller,
it's simpler and easier to understand.
The old code, for example, depended on the d_find_alias() to not just
find the dentry, but also to check that it is still hashed, which in
turn validated the tty pointer in the inode.
That is a _very_ roundabout way to say "invalidate the cached tty
pointer when the dentry is removed".
The new code just does
dentry->d_fsdata = NULL;
in devpts_pty_kill() instead, invalidating the tty pointer rather more
directly and obviously. Don't do something complex and subtle when the
obvious straightforward approach will do.
The rest of the patch (ie apart from code deletion and the above tty
pointer clearing) is just switching the calling convention to pass the
dentry or file pointer around instead of the inode.

When bpf(BPF_PROG_LOAD, ...) was invoked with a BPF program whose bytecode
references a non-map file descriptor as a map file descriptor, the error
handling code called fdput() twice instead of once (in __bpf_map_get() and
in replace_map_fd_with_map_ptr()). If the file descriptor table of the
current task is shared, this causes f_count to be decremented too much,
allowing the struct file to be freed while it is still in use
(use-after-free). This can be exploited to gain root privileges by an
unprivileged user.
This bug was introduced in
commit 0246e64d9a5f ("bpf: handle pseudo BPF_LD_IMM64 insn"), but is only
exploitable since
commit 1be7f75d1668 ("bpf: enable non-root eBPF programs") because
previously, CAP_SYS_ADMIN was required to reach the vulnerable code.

It was a simple idea -- save IPv6 configured addresses on a link down
so that IPv6 behaves similar to IPv4. As always the devil is in the
details and the IPv6 stack as too many behavioral differences from IPv4
making the simple idea more complicated than it needs to be.
The current implementation for keeping IPv6 addresses can panic or spit
out a warning in one of many paths:
1. IPv6 route gets an IPv4 route as its 'next' which causes a panic in
rt6_fill_node while handling a route dump request.
2. rt->dst.obsolete is set to DST_OBSOLETE_DEAD hitting the WARN_ON in
fib6_del
3. Panic in fib6_purge_rt because rt6i_ref count is not 1.
The root cause of all these is references related to the host route for
an address that is retained.
So, this patch deletes the host route every time the ifdown loop runs.
Since the host route is deleted and will be re-generated an up there is
no longer a need for the l3mdev fix up. On the 'admin up' side move
addrconf_permanent_addr into the NETDEV_UP event handling so that it
runs only once versus on UP and CHANGE events.
All of the current panics and warnings appear to be related to
addresses on the loopback device, but given the catastrophic nature when
a bug is triggered this patch takes the conservative approach and evicts
all host routes rather than trying to determine when it can be re-used
and when it can not. That can be a later optimizaton if desired.

Currently ARM CPUs DT bindings allows different enable-method value for
PSCI based systems. On ARM 64-bit this property is required and must be
"psci" while on ARM 32-bit systems this property is optional and must
be "arm,psci" if present.
However, "arm,psci" has always been the compatible string for the PSCI
node, and was never intended to be the enable-method. So this is a bug
in the binding and not a deliberate attempt at specifying 32-bit
differently.
This is problematic if 32-bit OS is run on 64-bit system which has
"psci" as enable-method rather than the expected "arm,psci".
So let's unify the value into "psci" and remove support for "arm,psci"
before it finds any users.

Set and report vport MTU rather than physical MTU,
Driver will set both vport and physical port mtu and will
rely on the query of vport mtu.
SRIOV VFs have to report their MTU to their vport manager (PF),
and this will allow them to work with any MTU they need
without failing the request.
Also for some cases where the PF is not a port owner, PF can
work with MTU less than the physical port mtu if set physical
port mtu didn't take effect.

Both socfpga_dwmac_parse_data() in dwmac-socfpga.c and stmmac_dvr_probe()
in stmmac_main.c functions call devm_reset_control_get() to register an
reset controller for the stmmac. This results in an attempt to register
two reset controllers for the same non-shared reset line.
The first attempt to register the reset controller works fine. The second
attempt fails with warning from the reset controller core, see below.
The warning is produced because the reset line is non-shared and thus
it is allowed to have only up-to one reset controller associated with
that reset line, not two or more.
The solution has multiple parts. First, the original socfpga_dwmac_init()
is tweaked to use reset controller pointer from the stmmac_priv (private
data of the stmmac core) instead of the local instance, which was used
before. The local re-registration of the reset controller is removed.
Next, the socfpga_dwmac_init() is moved after stmmac_dvr_probe() in the
probe function. This order is legal according to Altera and it makes the
code much easier, since there is no need to temporarily register and
unregister the reset controller ; the reset controller is already registered
by the stmmac_dvr_probe().
Finally, plat_dat->exit and socfpga_dwmac_exit() is no longer necessary,
since the functionality is already performed by the stmmac core.

The decrypt callback macsec_decrypt_done needs a reference on the rx_sa
and releases it before returning, but macsec_handle_frame already
put that reference after macsec_decrypt returned NULL.
Set rx_sa to NULL when the decrypt callback runs so that
macsec_handle_frame knows it must not release the reference.

The "deliver:" path of macsec_handle_frame can be called with
rx_sa == NULL. Check rx_sa != NULL before calling macsec_rxsa_put().

There is a race-condition when updating the mdb offload flag without using
the mulicast_lock. This reverts commit 9e8430f8d60d98 ("bridge: mdb:
Passing the port-group pointer to br_mdb module").
This patch marks offloaded MDB entry as "offload" by changing the port-
group flags and marks it as MDB_PG_FLAGS_OFFLOAD.
When switchdev PORT_MDB succeeded and adds a multicast group, a completion
callback is been invoked "br_mdb_complete". The completion function
locks the multicast_lock and finds the right net_bridge_port_group and
marks it as offloaded.

When using switchdev deferred operation (SWITCHDEV_F_DEFER), the operation
is executed in different context and the application doesn't have any way
to get the operation real status.
Adding a completion callback fixes that. This patch adds fields to
switchdev_attr and switchdev_obj "complete_priv" field which is used by
the "complete" callback.
Application can set a complete function which will be called once the
operation executed.
