This patch takes care of active/passive disconnect flows.
Disconnect flows can be initiated remotely, in which case a async event
will arrive from peer and indicated to qedr driver. These
are referred to as exceptions. When a QP is destroyed, it needs to check
that it's associated ep has been closed.

When a process runs out of stack the parisc kernel wrongly faults with SIGBUS
instead of the expected SIGSEGV signal.
This example shows how the kernel faults:

trap #15: Data TLB miss fault, vm_start = 0xfa2c2000, vm_end = 0xfaac2000
The vma->vm_end value is the first address which does not belong to the vma, so
adjust the check to include vma->vm_end to the range for which to send the
SIGSEGV signal.

====================
bpf: Add support for sock_ops
Created a new BPF program type, BPF_PROG_TYPE_SOCK_OPS, and a corresponding
struct that allows BPF programs of this type to access some of the
socket's fields (such as IP addresses, ports, etc.) and setting
connection parameters such as buffer sizes, initial window, SYN/SYN-ACK
RTOs, etc.
Unlike current BPF program types that expect to be called at a particular
place in the network stack code, SOCK_OPS program can be called at
different places and use an "op" field to indicate the context. There
are currently two types of operations, those whose effect is through
their return value and those whose effect is through the new
bpf_setsocketop BPF helper function.
Example operands of the first type are:
BPF_SOCK_OPS_TIMEOUT_INIT
BPF_SOCK_OPS_RWND_INIT
BPF_SOCK_OPS_NEEDS_ECN
Example operands of the secont type are:
BPF_SOCK_OPS_TCP_CONNECT_CB
BPF_SOCK_OPS_ACTIVE_ESTABLISHED_CB
BPF_SOCK_OPS_PASSIVE_ESTABLISHED_CB
Current operands are only called during connection establishment so
there should not be any BPF overheads after connection establishment. The
main idea is to use connection information form both hosts, such as IP
addresses and ports to allow setting of per connection parameters to
optimize the connection's peformance.
Alghough there are already 3 mechanisms to set parameters (sysctls,
route metrics and setsockopts), this new mechanism provides some
disticnt advantages. Unlike sysctls, it can set parameters per
connection. In contrast to route metrics, it can also use port numbers
and information provided by a user level program. In addition, it could
set parameters probabilistically for evaluation purposes (i.e. do
something different on 10% of the flows and compare results with the
other 90% of the flows). Also, in cases where IPv6 addresses contain
geographic information, the rules to make changes based on the distance
(or RTT) between the hosts are much easier than route metric rules and
can be global. Finally, unlike setsockopt, it does not require
application changes and it can be updated easily at any time.
It uses the existing bpf cgroups infrastructure so the programs can be
attached per cgroup with full inheritance support. Although the bpf cgroup
framework already contains a sock related program type (BPF_PROG_TYPE_CGROUP_SOCK),
I created the new type (BPF_PROG_TYPE_SOCK_OPS) beccause the existing type
expects to be called only once during the connections's lifetime. In contrast,
the new program type will be called multiple times from different places in the
network stack code. For example, before sending SYN and SYN-ACKs to set
an appropriate timeout, when the connection is established to set congestion
control, etc. As a result it has "op" field to specify the type of operation
requested.
This patch set also includes sample BPF programs to demostrate the differnet
features.
v2: Formatting changes, rebased to latest net-next
v3: Fixed build issues, changed socket_ops to sock_ops throught,
fixed formatting issues, removed the syscall to load sock_ops
program and added functionality to use existing bpf attach and
bpf detach system calls, removed reader/writer locks in
sock_bpfops.c (used when saving sock_ops global program)
and fixed missing module refcount increment.
v4: Removed global sock_ops program and instead used existing cgroup bpf
infrastructure to support a new BPF_CGROUP_ATTCH type.
v5: fixed kbuild warning happening in bpf-cgroup.h
removed automatic converstion to host byte order from some sock_ops
fields (ipv4 and ipv6 addresses, remote port)
Added conversion to host byte order in some of the sample programs
Added to sample BPF program comments about using load_sock_ops to load
Removed is_req_sock field from bpf_sock_ops_kern and related places,
using sk_fullsock() instead.
v6: fixes to BPF helper function setsockopt (possible NULL deferencing, etc.)

The purpose of this new program type is to simplify setting connection
parameters, such as buffer sizes, TCP's SYN RTO, etc. For example, it is
easy to use facebook's internal IPv6 addresses to determine if both hosts
of a connection are in the same datacenter. Therefore, it is easy to
write a BPF program to choose a small SYN RTO value when both hosts are
in the same datacenter.
This patch only contains the framework to support the new BPF program
type, following patches add the functionality to set various connection
parameters.
This patch defines a new BPF program type: BPF_PROG_TYPE_SOCKET_OPS
and a new bpf syscall command to load a new program of this type:
BPF_PROG_LOAD_SOCKET_OPS.
Two new corresponding structs (one for the kernel one for the user/BPF
program):
/* kernel version */
struct bpf_sock_ops_kern {
struct sock *sk;
__u32 op;
union {
__u32 reply;
__u32 replylong[4];
};
};
/* user version
* Some fields are in network byte order reflecting the sock struct
* Use the bpf_ntohl helper macro in samples/bpf/bpf_endian.h to
* convert them to host byte order.
*/
struct bpf_sock_ops {
__u32 op;
union {
__u32 reply;
__u32 replylong[4];
};
__u32 family;
__u32 remote_ip4; /* In network byte order */
__u32 local_ip4; /* In network byte order */
__u32 remote_ip6[4]; /* In network byte order */
__u32 local_ip6[4]; /* In network byte order */
__u32 remote_port; /* In network byte order */
__u32 local_port; /* In host byte horder */
};
Currently there are two types of ops. The first type expects the BPF
program to return a value which is then used by the caller (or a
negative value to indicate the operation is not supported). The second
type expects state changes to be done by the BPF program, for example
through a setsockopt BPF helper function, and they ignore the return
value.
The reply fields of the bpf_sockt_ops struct are there in case a bpf
program needs to return a value larger than an integer.

Based on a request raised on the sctp devel list, there is a need to
augment the sctp_peeloff operation while specifying the O_CLOEXEC and
O_NONBLOCK flags (simmilar to the socket syscall). Since modifying the
SCTP_SOCKOPT_PEELOFF socket option would break user space ABI for existing
programs, this patch creates a new socket option
SCTP_SOCKOPT_PEELOFF_FLAGS, which accepts a third flags parameter to
allow atomic assignment of the socket descriptor flags.

This patch fixes incorrect assignment for entry_type field for Continuation
Type iocb packet on BE system. This was caught by -Woverflow warning on BE
system compilation.
For Continuation Type iocb driver needs to write complete 32 bit value to
initialize other field members in structure to 0.
Following warning is seen on BE system compile:
drivers/scsi/qla2xxx/qla_nvme.c: In function 'qla2x00_start_nvme_mq':
include/uapi/linux/byteorder/big_endian.h:32:26: warning: large integer
implicitly truncated to unsigned type [-Woverflow]
#define __cpu_to_le32(x) ((__force __le32)__swab32((x)))
[mkp: fixed typo]

This reverts commits 2c0cba482e ("arm: sun8i: sunxi-h3-h5: Add dt node
for the syscon control module") to 2428fd0fe5 ("arm64: defconfig: Enable
dwmac-sun8i driver on defconfig") and 3432a86e64 ("arm: sun8i:
orangepipc: use internal phy-mode") to 5a79b4f2a5 ("arm: sun8i:
orangepi-2: use internal phy-mode") that should be merged
through the arm-soc tree, and end up in merge conflicts and build failures.

When NVMe support is disabled, we get a couple of harmless warnings:
drivers/scsi/qla2xxx/qla_nvme.c:667:13: error: 'qla_nvme_unregister_remote_port' defined but not used [-Werror=unused-function]
drivers/scsi/qla2xxx/qla_nvme.c:634:13: error: 'qla_nvme_abort_all' defined but not used [-Werror=unused-function]
drivers/scsi/qla2xxx/qla_nvme.c:604:12: error: 'qla_nvme_wait_on_rport_del' defined but not used [-Werror=unused-function]
This replaces the preprocessor checks in the code with equivalent
compiler conditionals, which lets gcc drop the unused functions without
warning, and is nicer to read.
