In MPTCP, the receive window is shared across all subflows, because it
refers to the mptcp-level sequence space.

MPTCP receivers already place incoming packets on the mptcp socket
receive queue and will charge it to the mptcp socket rcvbuf until
userspace consumes the data.

Update __tcp_select_window to use the occupancy of the parent/mptcp
socket instead of the subflow socket in case the tcp socket is part
of a logical mptcp connection.

This commit doesn't change choice of initial window for passive or active
connections.
While it would be possible to change those as well, this adds complexity
(especially when handling MP_JOIN requests).  Furthermore, the MPTCP RFC
specifically says that a MPTCP sender 'MUST NOT use the RCV.WND field
of a TCP segment at the connection level if it does not also carry a DSS
option with a Data ACK field.'

SYN/SYNACK packets do not carry a DSS option with a Data ACK field.

net: hns3: refactor for MAC table

This patchset refactors the MAC table management, configure
the MAC address asynchronously, instead of synchronously.
Base on this change, it also refines the handle of promisc
mode and filter table entries restoring after reset.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

Currently, the PF driver removes all (including its VFs') MAC/VLAN
flow director table entries when resetting, and restores them after
reset completed.

In fact, the hardware will clear all table entries only in IMP
reset and global reset. So driver only needs to restore the table
entries in these cases, and needs do nothing when PF reset, FLR
or other function level reset.

This patch optimizes it by removing unnecessary table entries clear
and restoring handling in the reset flow, and doing the restoring
after reset completed.

Currently, the driver use mutex umv_lock to protect the variable
vport->share_umv_size. And there is already a mutex vport_lock
being defined in the driver, which is designed to protect the
resource of vport. So we can use vport_lock instead of umv_lock.

Furthermore, there is a time window for protect share_umv_size
between checking UMV space and doing MAC configuration in the
lin function hclge_add_uc_addr_common(). It should be extended.

This patch uses mutex vport_lock intead of spin lock umv_lock to
protect share_umv_size, and adjusts the mutex's range.

Currently, the HNS3 driver sync and unsync MAC address in function
hns3_set_rx_mode(). For PF, it adds and deletes MAC address directly
in the path of dev_set_rx_mode(). If failed, it won't retry until
next calling of hns3_set_rx_mode(). On the other hand, if request
add and remove a same address many times at a short interval, each
request must be done one by one, can't be merged. For VF, it sends
mailbox messages to PF to request adding or deleting MAC address in
the path of function hns3_set_rx_mode(), no matter the address is
configured success.

This patch refines it by recording the MAC address in function
hns3_set_rx_mode(), and updating MAC address in the service task.
If failed, it will retry by the next calling of periodical service
task. It also uses some state to mark the state of each MAC address
in the MAC list, which can help merge configure request for a same
address. With these changes, when global reset or IMP reset occurs,
we can restore the MAC table with the MAC list.

vmlinux.h, generated by runqslower's own Makefile. When runqslower is built
from selftests/bpf, due to current -I$(BPF_INCLUDE) -I$(OUTPUT) ordering, it
might pick up not-yet-complete vmlinux.h, generated by selftests Makefile,
which could lead to compilation errors like [0]. So ensure that -I$(OUTPUT)
goes first and rely on runqslower's Makefile own dependency chain to ensure
vmlinux.h is properly completed before source code relying on it is compiled.

For some program types, the verifier relies on the expected_attach_type of
the program being verified in the verification process. However, for
freplace programs, the attach type was not propagated along with the
verifier ops, so the expected_attach_type would always be zero for freplace
programs.

This in turn caused the verifier to sometimes make the wrong call for
freplace programs. For all existing uses of expected_attach_type for this
purpose, the result of this was only false negatives (i.e., freplace
functions would be rejected by the verifier even though they were valid
programs for the target they were replacing). However, should a false
positive be introduced, this can lead to out-of-bounds accesses and/or
crashes.

The fix introduced in this patch is to propagate the expected_attach_type
to the freplace program during verification, and reset it after that is
done.

The current JIT clobbers the destination register for BPF_JSET BPF_X
and BPF_K by using "and" and "or" instructions. This is fine when the
destination register is a temporary loaded from a register stored on
the stack but not otherwise.

This patch fixes the problem (for both BPF_K and BPF_X) by always loading
the destination register into temporaries since BPF_JSET should not
modify the destination register.

This bug may not be currently triggerable as BPF_REG_AX is the only
register not stored on the stack and the verifier uses it in a limited
way.

The current JIT uses the following sequence to zero-extend into the
upper 32 bits of the destination register for BPF_LDX BPF_{B,H,W},
when the destination register is not on the stack:

  EMIT3(0xC7, add_1reg(0xC0, dst_hi), 0);

The problem is that C7 /0 encodes a MOV instruction that requires a 4-byte
immediate; the current code emits only 1 byte of the immediate. This
means that the first 3 bytes of the next instruction will be treated as
the rest of the immediate, breaking the stream of instructions.

This patch fixes the problem by instead emitting "xor dst_hi,dst_hi"
to clear the upper 32 bits. This fixes the problem and is more efficient
than using MOV to load a zero immediate.

This bug may not be currently triggerable as BPF_REG_AX is the only
register not stored on the stack and the verifier uses it in a limited
way, and the verifier implements a zero-extension optimization. But the
JIT should avoid emitting incorrect encodings regardless.
