Some drivers use IEEE80211_KEY_FLAG_SW_MGMT_TX to indicate that management
frames need to be software encrypted. Since normal data packets are still
encrypted by the hardware, crypto_tx_tailroom_needed_cnt gets decremented
after key upload to hw. This can lead to passing skbs to ccmp_encrypt_skb,
which don't have the necessary tailroom for software encryption.
Change the code to add tailroom for encrypted management packets, even if
crypto_tx_tailroom_needed_cnt is 0.

In typical cases, there's no need to pass both the maxattr
and the policy array pointer, as the maxattr should just be
ARRAY_SIZE(policy) - 1. Therefore, to be less error prone,
just remove the maxattr argument from the default macros
and deduce the size accordingly.
Leave the original macros with a leading underscore to use
here and in case somebody needs to pass a policy pointer
where the policy isn't declared in the same place and thus
ARRAY_SIZE() cannot be used.

Al Viro pointed out that since there is only one pipe buffer type to which
new data can be appended, it isn't necessary to have a ->can_merge field in
struct pipe_buf_operations, we can just check for a magic type.

syzbot was able to catch a bug in rds [1]
The issue here is that the socket might be found in a hash table
but that its refcount has already be set to 0 by another cpu.
We need to use refcount_inc_not_zero() to be safe here.

The size of L2TPv2 header with all optional fields is 14 bytes.
l2tp_udp_recv_core only moves 10 bytes to the linear part of a
skb. This may lead to l2tp_recv_common read data outside of a skb.
This patch make sure that there is at least 14 bytes in the linear
part of a skb to meet the maximum need of l2tp_udp_recv_core and
l2tp_recv_common. The minimum size of both PPP HDLC-like frame and
Ethernet frame is larger than 14 bytes, so we are safe to do so.
Also remove L2TP_HDR_SIZE_NOSEQ, it is unused now.

Use pskb_may_pull() to make sure the optional fields are in skb linear
parts, so we can safely read them later.
It's easy to reproduce the issue with a net driver that supports paged
skb data. Just create a L2TPv3 over IP tunnel and then generates some
network traffic.
Once reproduced, rx err in /sys/kernel/debug/l2tp/tunnels will increase.
Changes in v4:
1. s/l2tp_v3_pull_opt/l2tp_v3_ensure_opt_in_linear/
2. s/tunnel->version != L2TP_HDR_VER_2/tunnel->version == L2TP_HDR_VER_3/
3. Add 'Fixes' in commit messages.
Changes in v3:
1. To keep consistency, move the code out of l2tp_recv_common.
2. Use "net" instead of "net-next", since this is a bug fix.
Changes in v2:
1. Only fix L2TPv3 to make code simple.
To fix both L2TPv3 and L2TPv2, we'd better refactor l2tp_recv_common.
It's complicated to do so.
2. Reloading pointers after pskb_may_pull

skb->cb may contain data from previous layers (in an observed case
IPv4 with L3 Master Device). In the observed scenario, the data in
IPCB(skb)->frags was misinterpreted as IP6CB(skb)->frag_max_size,
eventually caused an unexpected IPv6 fragmentation in ip6_fragment()
through ip6_finish_output().
This patch clears IP6CB(skb), which potentially contains garbage data,
on the SRH ip4ip6 encapsulation.

As Erspan_v4, Erspan_v6 protocol relies on o_key to configure
session id header field. However TUNNEL_KEY bit is cleared in
ip6erspan_tunnel_xmit since ERSPAN protocol does not set the key field
of the external GRE header and so the configured o_key is not reported
to userspace. The issue can be triggered with the following reproducer:
$ip link add ip6erspan1 type ip6erspan local 2000::1 remote 2000::2 \

As reported by Robert O'Callahan in
https://bugzilla.kernel.org/show_bug.cgi?id=202273
reverting the previous changes in this area broke
the SIOCGIFNAME ioctl in compat again (I'd previously
fixed it after his previous report of breakage in
https://bugzilla.kernel.org/show_bug.cgi?id=199469).
This is obviously because I fixed SIOCGIFNAME more or
less by accident.
Fix it explicitly now by making it pass through the
restored compat translation code.

This reverts commit bf4405737f9f ("kill dev_ifsioc()").
This wasn't really unused as implied by the original commit,
it still handles the copy to/from user differently, and the
commit thus caused issues such as
https://bugzilla.kernel.org/show_bug.cgi?id=199469
and
https://bugzilla.kernel.org/show_bug.cgi?id=202273
However, deviating from a strict revert, rename dev_ifsioc()
to compat_ifreq_ioctl() to be clearer as to its purpose and
add a comment.

inserting in sctp_id2assoc and sctp_assoc_set_id.

wake_on_lan - Enables Wake on Lan for this port. If enabled,
the controller asserts a wake pin based on the WOL type.
v2->v3:
- Define only WOL types used now and define them as bitfield, so that
mutliple WOL types can be enabled upon power on.
- Modify "wake-on-lan" name to "wake_on_lan" to be symmetric with
previous definitions.
- Rename DEVLINK_PARAM_WOL_XXX to DEVLINK_PARAM_WAKE_XXX to be
symmetrical with ethtool WOL definitions.

Add notification call for devlink port param set, register and unregister
functions.
Add devlink_port_param_value_changed() function to enable the driver notify
devlink on value change. Driver should use this function after value was
changed on any configuration mode part to driverinit.
v7->v8:
Order devlink_port_param_value_changed() definitions followed by
devlink_param_value_changed()

Add support for "driverinit" configuration mode value for devlink_port
configuration parameters. Add devlink_port_param_driverinit_value_set()
function to help the driver set the value to devlink_port.
Also, move the common code to __devlink_param_driverinit_value_set()
to be used by both device and port params.
v7->v8:
Re-order the definitions as follows:
__devlink_param_driverinit_value_get
__devlink_param_driverinit_value_set
devlink_param_driverinit_value_get
devlink_param_driverinit_value_set
devlink_port_param_driverinit_value_get
devlink_port_param_driverinit_value_set

Add support for "driverinit" configuration mode value for devlink_port
configuration parameters. Add devlink_port_param_driverinit_value_get()
function to help the driver get the value from devlink_port.
Also, move the common code to __devlink_param_driverinit_value_get()
to be used by both device and port params.
v7->v8:
-Add the missing devlink_port_param_driverinit_value_get() declaration.
-Also, order devlink_port_param_driverinit_value_get() after
devlink_param_driverinit_value_get/set() calls

Add functions to register and unregister for the driver supported
configuration parameters table per port.
v7->v8:
- Order the definitions following way as suggested by Jiri.
__devlink_params_register
__devlink_params_unregister
devlink_params_register
devlink_params_unregister
devlink_port_params_register
devlink_port_params_unregister
- Append with Acked-by: Jiri Pirko <jiri@mellanox.com>.
v2->v3:
- Add a helper __devlink_params_register() with common code used by
both devlink_params_register() and devlink_port_params_register().

Assign a default net namespace to netdevs created by init_dummy_netdev().
Fixes a NULL pointer dereference caused by busy-polling a socket bound to
an iwlwifi wireless device, which bumps the per-net BUSYPOLLRXPACKETS stat
if napi_poll() received packets:

If there are outstanding async tx requests (when crypto returns EINPROGRESS),
there is a potential deadlock: the tx work acquires the lock, while we
cancel_delayed_work_sync() while holding the lock. Drop the lock while waiting
for the work to complete.
