The current code does not check sk->sk_shutdown & RCV_SHUTDOWN.
tls_sw_recvmsg may return a positive value in the case where bytes have
already been copied when the socket is shutdown. sk->sk_err has been
cleared, causing the tls_wait_data to hang forever on a subsequent
invocation. Checking sk->sk_shutdown & RCV_SHUTDOWN, as in tcp_recvmsg,
fixes this problem.

====================
fix DCTCP ECE Ack series
This patch set address that the existing DCTCP implementation does not
fully implement the ACK policy specified in the RFC. This improves
the responsiveness of CE status change particularly on flows with
small inflight.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Per DCTCP RFC8257 (Section 3.2) the ACK reflecting the CE status change
has to be sent immediately so the sender can respond quickly:
""" When receiving packets, the CE codepoint MUST be processed as follows:
1. If the CE codepoint is set and DCTCP.CE is false, set DCTCP.CE to
true and send an immediate ACK.
2. If the CE codepoint is not set and DCTCP.CE is true, set DCTCP.CE
to false and send an immediate ACK.
"""
Previously DCTCP implementation may continue to delay the ACK. This
patch fixes that to implement the RFC by forcing an immediate ACK.

Currently when a DCTCP receiver delays an ACK and receive a
data packet with a different CE mark from the previous one's, it
sends two immediate ACKs acking previous and latest sequences
respectly (for ECN accounting).
Previously sending the first ACK may mark off the delayed ACK timer
(tcp_event_ack_sent). This may subsequently prevent sending the
second ACK to acknowledge the latest sequence (tcp_ack_snd_check).
The culprit is that tcp_send_ack() assumes it always acknowleges
the latest sequence, which is not true for the first special ACK.
The fix is to not make the assumption in tcp_send_ack and check the
actual ack sequence before cancelling the delayed ACK. Further it's
safer to pass the ack sequence number as a local variable into
tcp_send_ack routine, instead of intercepting tp->rcv_nxt to avoid
future bugs like this.

The commit referred to below introduced an update of the link
capabilities field that is not safe. Given the recently added
feature to remove idle node and link items after 5 minutes, there
is a small risk that the update will happen at the very moment the
targeted link is being removed. To avoid this we have to perform
the update inside the node item's write lock protection.

VPID for the nested vcpu is allocated at vmx_create_vcpu whenever nested
vmx is turned on with the module parameter.
However, it's only freed if the L1 guest has executed VMXON which is not
a given.
As a result, on a system with nested==on every creation+deletion of an
L1 vcpu without running an L2 guest results in leaking one vpid. Since
the total number of vpids is limited to 64k, they can eventually get
exhausted, preventing L2 from starting.
Delay allocation of the L2 vpid until VMXON emulation, thus matching its
freeing.

There is a bug in the sink PDO search code when trying to select
a PPS APDO. The current code actually sets the starting index for
searching to whatever value 'i' is, rather than choosing index 1
to avoid the first PDO (always 5V fixed). As a result, for sources
which support PPS but whose PPS APDO index does not match with the
supporting sink PPS APDO index for the platform, no valid PPS APDO
will be found so this feature will not be permitted.
Sadly in testing, both Source and Sink capabilities matched up and
this was missed. Code is now updated to correctly set the start
index to 1, and testing with additional PPS capable sources show
this to work as expected.

Commit 1b9ba000 ("Allow function drivers to pause control
transfers") states that USB_GADGET_DELAYED_STATUS is only
supported if data phase is 0 bytes.
It seems that when the length is not 0 bytes, there is no
need to explicitly delay the data stage since the transfer
is not completed until the user responds. However, when the
length is 0, there is no data stage and the transfer is
finished once setup() returns, hence there is a need to
explicitly delay completion.
This manifests as the following bugs:
Prior to 946ef68ad4e4 ('Let setup() return
USB_GADGET_DELAYED_STATUS'), when setup is 0 bytes, ffs
would require user to queue a 0 byte request in order to
clear setup state. However, that 0 byte request was actually
not needed and would hang and cause errors in other setup
requests.
After the above commit, 0 byte setups work since the gadget
now accepts empty queues to ep0 to clear the delay, but all
other setups hang.

laptops anymore, but was present in older kernel versions.
The code that checks the return value is incorrect since the SMM

Which was changed to:

if (ret)
However, dell_send_request() will return 0 if buffer->output[0] == 0,
so we must change the check to:
if (ret == 0)

In order to remove performance impact of having the extra u32 in every
single flowi, this change removes the flowi_xfrm struct, prefering to
take the if_id as a method parameter where needed.
In the inbound direction, if_id is only needed during the
__xfrm_check_policy() function, and the if_id can be determined at that
point based on the skb. As such, xfrmi_decode_session() is only called
with the skb in __xfrm_check_policy().
In the outbound direction, the only place where if_id is needed is the
xfrm_lookup() call in xfrmi_xmit2(). With this change, the if_id is
directly passed into the xfrm_lookup_with_ifid() call. All existing
callers can still call xfrm_lookup(), which uses a default if_id of 0.
This change does not change any behavior of XFRMIs except for improving
overall system performance via flowi size reduction.

The calculation of "wqe_size" is not correct when the tx queue is busy in
hinic_xmit_frame().
When there are no free WQEs, the tx flow will unmap the skb buffer, then
ring the doobell for the pending packets. But the "wqe_size" which used
to calculate the doorbell address is not correct. The wqe size should be
cleared to 0, otherwise, it will cause a doorbell error.
This patch fixes the problem.

Or Gerlitz says
====================
set/match the tos/ttl fields of TC based IP tunnels
This series comes to address the case to set (encap) and match (decap)
also the tos and ttl fields of TC based IP tunnels.
Example encap (1st one) and decap (2nd) that use the new fields
tc filter add dev eth0_0 protocol ip parent ffff: prio 10 flower \
src_mac e4:11:22:33:44:50 dst_mac e4:11:22:33:44:70 \
action tunnel_key set src_ip 192.168.10.1 dst_ip 192.168.10.2 id 100 dst_port 4789 tos 0x30 \
action mirred egress redirect dev vxlan_sys_4789
tc filter add dev vxlan_sys_4789 protocol ip parent ffff: prio 10 flower \
enc_src_ip 192.168.10.2 enc_dst_ip 192.168.10.1 enc_key_id 100 enc_dst_port 4789 enc_tos 0x30 \
src_mac e4:11:22:33:44:70 dst_mac e4:11:22:33:44:50 \
action tunnel_key unset \

Fix the warning below by calling the ptr_ring_consume_bh,
