A broken device may give an extreme offset like 0xFFF0
and a reasonable length for a fragment. In the sanity
check as formulated now, this will create an integer
overflow, defeating the sanity check. Both offset
and offset + len need to be checked in such a manner
that no overflow can occur.
And those quantities should be unsigned.

ocelot_vlan_member_del() will free the struct ocelot_bridge_vlan, so if
this is the same as the port's pvid_vlan which we access afterwards,
what we're accessing is freed memory.
Fix the bug by determining whether to clear ocelot_port->pvid_vlan prior
to calling ocelot_vlan_member_del().

When multiple containers are running in the environment and multiple
macvlan network port are configured in each container, a lot of martian
source prints will appear after martian_log is enabled. they are almost
the same, and printed by net_warn_ratelimited. Each arp message will
trigger this print on each network port.

alg_memory_allocated does not seem to be really used.
alg_proto does have a .memory_allocated field, but no
corresponding .sysctl_mem.
This means sk_has_account() returns true, but all sk_prot_mem_limits()
users will trigger a NULL dereference [1].
THis was not a problem until SO_RESERVE_MEM addition.

When a link comes up we add its presence to the name table to make it
possible for users to subscribe for link up/down events. However, after
a previous call signature change the binding is wrongly published with
the peer node as publishing node, instead of the own node as it should
be. This has the effect that the command 'tipc name table show' will
list the link binding (service type 2) with node scope and a peer node
as originator, something that obviously is impossible.
We correct this bug here.

On newer AMD platforms with SFH, it is observed that random interrupts
get generated on the SFH hardware and until this is cleared the firmware
sensor processing is stalled, resulting in no data been received to
driver side.

not stalled.

scheduling a delayed work adds no value.

Fixes return value documentation of kernel_getsockname()
and kernel_getpeername() functions.
The previous documentation wrongly specified that the return
value is 0 in case of success, however sock->ops->getname returns
the length of the address in bytes in case of success.

mv88e6xxx is special among DSA drivers in that it requires the VTU to
contain the VID of the FDB entry it modifies in
mv88e6xxx_port_db_load_purge(), otherwise it will return -EOPNOTSUPP.
Sometimes due to races this is not always satisfied even if external
code does everything right (first deletes the FDB entries, then the
VLAN), because DSA commits to hardware FDB entries asynchronously since
commit c9eb3e0f8701 ("net: dsa: Add support for learning FDB through
notification").
Therefore, the mv88e6xxx driver must close this race condition by
itself, by asking DSA to flush the switchdev workqueue of any FDB
deletions in progress, prior to exiting a VLAN.

Some time ago 8965779d2c0e ("ipv6,mcast: always hold idev->lock before mca_lock")
switched ipv6_get_lladdr() to __ipv6_get_lladdr(), which is rcu-unsafe
version. That was OK, because idev->lock was held for these codepaths.
In 88e2ca308094 ("mld: convert ifmcaddr6 to RCU") these external locks were
removed, so we probably need to restore the original rcu-safe call.
Otherwise, we occasionally get a machine crashed/stalled with the following

After commit 4b9d2a731c3d ("parisc: Switch user access functions
to signal errors in r29 instead of r8") bash suddenly started
to report those warnings after login:
-bash: cannot set terminal process group (-1): Bad file descriptor
-bash: no job control in this shell
It turned out, that a function call inside a put_user(), e.g.:
put_user(vt_do_kdgkbmode(console), (int __user *)arg);
clobbered the error register (r29) and thus the put_user() call itself
seem to have failed.
Rearrange the C-code to pre-calculate the intermediate value
and then do the put_user().
Additionally prefer the "+" constraint on pu_err and gu_err registers
to tell the compiler that those operands are both read and written by
the assembly instruction.

The COMMS package can enable the hardware parser to recognize IPSEC
frames with ESP header and SPI identifier. If this package is available
and configured for loading in /lib/firmware, then the driver will
succeed in enabling this protocol type for RSS.
This in turn allows the hardware to hash over the SPI and use it to pick
a consistent receive queue for the same secure flow. Without this all
traffic is steered to the same queue for multiple traffic threads from
the same IP address. For that reason this is marked as a fix, as the
driver supports the model, but it wasn't enabled.
If the package is not available, adding this type will fail, but the
failure is ignored on purpose as it has no negative affect.

use the correct ARCH= option.
