VRF devices use an optimized direct path on output if a default qdisc
is involved, calling Netfilter hooks directly. This path, however, does
not consider Netfilter rules completing asynchronously, such as with
NFQUEUE. The Netfilter okfn() is called for asynchronously accepted
packets, but the VRF never passes that packet down the stack to send
it out over the slave device. Using the slower redirect path for this
seems not feasible, as we do not know beforehand if a Netfilter hook
has asynchronously completing rules.
Fix the use of asynchronously completing Netfilter rules in OUTPUT and
POSTROUTING by using a special completion function that additionally
calls dst_output() to pass the packet down the stack. Also, slightly
adjust the use of nf_reset_ct() so that is called in the asynchronous
case, too.

====================
cxgb4/ch_ktls: Fixes in nic tls code
This series helps in fixing multiple nic ktls issues. Series is broken
into 12 patches.
Patch 1 avoids deciding tls packet based on decrypted bit. If its a
retransmit packet which has tls handshake and finish (for encryption),
decrypted bit won't be set there, and so we can't rely on decrypted
bit.
Patch 2 helps supporting linear skb. SKBs were assumed non-linear.
Corrected the length extraction.
Patch 3 fixes the checksum offload update in WR.
Patch 4 fixes kernel panic happening due to creating new skb for each
record. As part of fix driver will use same skb to send out one tls
record (partial data) of the same SKB.
Patch 5 fixes the problem of skb data length smaller than remaining data
of the record.
Patch 6 fixes the handling of SKBs which has tls header alone pkt, but
not starting from beginning.
Patch 7 avoids sending extra data which is used to make a record 16 byte
aligned. We don't need to retransmit those extra few bytes.
Patch 8 handles the cases where retransmit packet has tls starting
exchanges which are prior to tls start marker.
Patch 9 fixes the problem os skb free before HW knows about tcp FIN.
Patch 10 handles the small packet case which has partial TAG bytes only.
HW can't handle those, hence using sw crypto for such pkts.
Patch 11 corrects the potential tcb update problem.
Patch 12 stops the queue if queue reaches threshold value.
v1->v2:
- Corrected fixes tag issue.
- Marked chcr_ktls_sw_fallback() static.

Creating SKB per tls record and freeing the original one causes
panic. There will be race if connection reset is requested. By
freeing original skb, refcnt will be decremented and that means,
there is no pending record to send, and so tls_dev_del will be
requested in control path while SKB of related connection is in
queue.
Better approach is to use same SKB to send one record (partial
data) at a time. We still have to create a new SKB when partial
last part of a record is requested.
This fix introduces new API cxgb4_write_partial_sgl() to send
partial part of skb. Present cxgb4_write_sgl can only provide
feasibility to start from an offset which limits to header only
and it can write sgls for the whole skb len. But this new API
will help in both. It can start from any offset and can end
writing in middle of the skb.

lan743x_dp_write(), which acquires a mutex. Mutex acquisition
may sleep, and this is not allowed when holding a spinlock.
Fix by removing the dp_lock mutex entirely. Its purpose is to

Commit 6f197fb638 ("lan743x: Added fixed link and RGMII support")
assumes that chips with an internal PHY will never have a devicetree
entry. This is incorrect: even for these chips, a devicetree entry
can be useful e.g. to pass the mac address from bootloader to chip:
&pcie {
status = "okay";
host@0 {
reg = <0 0 0 0 0>;
#address-cells = <3>;
#size-cells = <2>;
lan7430: ethernet@0 {
/* LAN7430 with internal PHY */
compatible = "microchip,lan743x";
status = "okay";
reg = <0 0 0 0 0>;
/* filled in by bootloader */
local-mac-address = [00 00 00 00 00 00];
};
};
};
If a devicetree entry is present, the driver will not attach the chip
to its internal phy, and the chip will be non-operational.
Fix by tweaking the phy connection algorithm:
- first try to connect to a phy specified in the devicetree
(could be 'real' phy, or just a 'fixed-link')
- if that doesn't succeed, try to connect to an internal phy, even
if the chip has a devnode
Tested on a LAN7430 with internal PHY. I cannot test a device using
fixed-link, as I do not have access to one.

After updating userspace Ethtool from 5.7 to 5.9, I noticed that
NETDEV_FEAT_CHANGE is no more raised when changing netdev features
through Ethtool.
That's because the old Ethtool ioctl interface always calls
netdev_features_change() at the end of user request processing to
inform the kernel that our netdevice has some features changed, but
the new Netlink interface does not. Instead, it just notifies itself
with ETHTOOL_MSG_FEATURES_NTF.
Replace this ethtool_notify() call with netdev_features_change(), so
the kernel will be aware of any features changes, just like in case
with the ioctl interface. This does not omit Ethtool notifications,
as Ethtool itself listens to NETDEV_FEAT_CHANGE and drops
ETHTOOL_MSG_FEATURES_NTF on it
(net/ethtool/netlink.c:ethnl_netdev_event()).
From v1 [1]:
- dropped extra new line as advised by Jakub;

Jianlin reports that a bridged IPv6 VXLAN endpoint, carrying IPv6
packets over a link with a PMTU estimation of exactly 1350 bytes,
won't trigger ICMPv6 Packet Too Big replies when the encapsulated
datagrams exceed said PMTU value. VXLAN over IPv6 adds 70 bytes of
overhead, so an ICMPv6 reply indicating 1280 bytes as inner MTU
would be legitimate and expected.
This comes from an off-by-one error I introduced in checks added
as part of commit 4cb47a8644 ("tunnels: PMTU discovery support
for directly bridged IP packets"), whose purpose was to prevent
sending ICMPv6 Packet Too Big messages with an MTU lower than the
smallest permissible IPv6 link MTU, i.e. 1280 bytes.
In iptunnel_pmtud_check_icmpv6(), avoid triggering a reply only if
the advertised MTU would be less than, and not equal to, 1280 bytes.
Also fix the analogous comparison for IPv4, that is, skip the ICMP
reply only if the resulting MTU is strictly less than 576 bytes.
This becomes apparent while running the net/pmtu.sh bridged VXLAN
or GENEVE selftests with adjusted lower-link MTU values. Using
e.g. GENEVE, setting ll_mtu to the values reported below, in the
test_pmtu_ipvX_over_bridged_vxlanY_or_geneveY_exception() test
function, we can see failures on the following tests:
test | ll_mtu

pmtu_ipv4_br_geneve4_exception | 626
pmtu_ipv6_br_geneve4_exception | 1330
pmtu_ipv6_br_geneve6_exception | 1350

Due to the legacy usage of hard_header_len for SIT tunnels while
already using infrastructure from net/ipv4/ip_tunnel.c the
calculation of the path MTU in tnl_update_pmtu is incorrect.
This leads to unnecessary creation of MTU exceptions for any
flow going over a SIT tunnel.
As SIT tunnels do not have a header themsevles other than their
transport (L3, L2) headers we're leaving hard_header_len set to zero
as tnl_update_pmtu is already taking care of the transport headers
sizes.
This will also help avoiding unnecessary IPv6 GC runs and spinlock
contention seen when using SIT tunnels and for more than
net.ipv6.route.gc_thresh flows.

RTL8125B has same or similar short packet hw padding bug as RTL8168evl.
The main workaround has been extended accordingly, however we have to
disable also hw checksumming for short packets on affected new chip
versions. Instead of checking for an affected chip version let's
simply disable hw checksumming for short packets in general.
v2:
- remove the version checks and disable short packet hw csum in general
- reflect this in commit title and message

The caller of rtl8169_tso_csum_v2() frees the skb if false is returned.
eth_skb_pad() internally frees the skb on error what would result in a
double free. Therefore use __skb_put_padto() directly and instruct it
to not free the skb on error.

The current logic checks if the name of the BTF type passed in
attach_btf_id starts with "bpf_lsm_", this is not sufficient as it also
allows attachment to non-LSM hooks like the very function that performs
this check, i.e. bpf_lsm_verify_prog.
In order to ensure that this verification logic allows attachment to
only LSM hooks, the LSM_HOOK definitions in lsm_hook_defs.h are used to
generate a BTF_ID set. Upon verification, the attach_btf_id of the
program being attached is checked for presence in this set.

"It's Friday here so that means another installment of drm fixes to
distract you from the counting process.
Changes all over the place, the amdgpu changes contain support for a
new GPU that is close to current one already in the tree (Green
Sardine) so it shouldn't have much side effects.
Otherwise imx has a few cleanup patches and fixes, amdgpu and i915
have around the usual smattering of fixes, fonts got constified, and
vc4/panfrost has some minor fixes. All in all a fairly regular rc3.
We have an outstanding nouveau regression, but the author is looking
into the fix, so should be here next week.
