The only caller (svc_send) has already checked XPT_DEAD.

If any xprt marked DEAD is also left BUSY for the rest of its life, then
the XPT_DEAD check here is superfluous--we'll get the same result from
the XPT_BUSY check just after.

As long as DEAD exports are left BUSY, and svc_delete_xprt is called
only with BUSY held, then svc_delete_xprt() will never be called on an
xprt that is already DEAD.

Once an xprt has been deleted, there's no reason to allow it to be
enqueued--at worst, that might cause the xprt to be re-added to some
global list, resulting in later corruption.
Also, note this leaves us with no need for the reference-count
manipulation here.

This appears to be caused by the function rpc_verify_header() first
calling xprt_release(), then doing a call_refresh. If we release the
transport slot, we should _always_ jump back to call_reserve before
calling anything else.

The REDIRECT target and the older TProxy versions used the primary address
of the incoming interface as the default value of the --on-ip parameter.
This was unintentionally changed during the initial TProxy submission and
caused confusion among users.
Since IPv6 has no notion of primary address, we just select the first address
on the list: this way the socket lookup finds wildcard bound sockets
properly and we cannot really do better without the user telling us the
IPv6 address of the proxy.
This is implemented for both IPv4 and IPv6.

The source address field in the transport's sock_xprt is initialized
ONLY IF the RPC application passed a pointer to a source address
during the call to rpc_create(). However, xs_bind() subsequently uses
the value of this field without regard to whether the source address
was initialized during transport creation or not.
So far we've been lucky: the uninitialized value of this field is
zeroes. xs_bind(), until recently, used only the sin[6]_addr field in
this sockaddr, and all zeroes is a valid value for this: it means
ANYADDR. This is a happy coincidence.
However, xs_bind() now wants to use the sa_family field as well, and
expects it to be initialized to something other than zero.
Therefore, the source address sockaddr field should be fully
initialized at transport create time in _every_ case, not just when
the RPC application wants to use a specific bind address.
Bruce added a workaround for this missing initialization by adjusting
commit 6bc9638a, but the "right" way to do this is to ensure that the
source address sockaddr is always correctly initialized from the
get-go.
This patch doesn't introduce a behavior change. It's simply a
clean-up of Bruce's fix, to prevent future problems of this kind. It
may look like overkill, but
a) it clearly documents the default initial value of this field,
b) it doesn't assume that the sockaddr_storage memory is first
initialized to any particular value, and
c) it will fail verbosely if some unknown address family is passed
in

* Create and use svc_rdma_wq instead of using the system workqueue and
flush_scheduled_work(). This workqueue is necessary to serve as
flushing domain for rdma->sc_work which is used to destroy itself
and thus can't be flushed explicitly.
* Replace cancel_delayed_work() + flush_scheduled_work() with
cancel_delayed_work_sync().
* Implement synchronous connect in xprt_rdma_connect() using
flush_delayed_work() on the rdma_connect work instead of using
flush_scheduled_work().
This is to prepare for the deprecation and removal of
flush_scheduled_work().

Just like with IPv4, we need access to the UDP hash table to look up local
sockets, but instead of exporting the global udp_table, export a lookup
function.

The parameters for various UDP lookup functions were non-const, even though
they could be const. TProxy has some const references and instead of
downcasting it, I added const specifiers along the path.

Like with IPv4, TProxy needs IPv6 defragmentation but does not
require connection tracking. Since defragmentation was coupled
with conntrack, I split off the two, creating an nf_defrag_ipv6 module,
similar to the already existing nf_defrag_ipv4.

With all the patches we have queued in the BKL removal tree, only a
few dozen modules are left that actually rely on the BKL, and even
there are lots of low-hanging fruit. We need to decide what to do
about them, this patch illustrates one of the options:
Every user of the BKL is marked as 'depends on BKL' in Kconfig,
and the CONFIG_BKL becomes a user-visible option. If it gets
disabled, no BKL using module can be built any more and the BKL
code itself is compiled out.
The one exception is file locking, which is practically always
enabled and does a 'select BKL' instead. This effectively forces
CONFIG_BKL to be enabled until we have solved the fs/lockd
mess and can apply the patch that removes the BKL from fs/locks.c.

Skip ICMP translation of embedded protocol header
if NAT bits are not set. Needed for IPVS to see the original
embedded addresses because for IPVS traffic the IPS_SRC_NAT_BIT
and IPS_DST_NAT_BIT bits are not set. It happens when IPVS performs
DNAT for client packets after using nf_conntrack_alter_reply
to expect replies from real server.

CAN has no addressing scheme. It is currently impossible for userspace
to tell is a received CAN frame comes from another process on the local
host, or from a remote CAN device.
This patch add support for userspace applications to distinguish between
'own', 'local' and 'remote' CAN traffic. The distinction is made by returning
flags in msg->msg_flags in the call to recvmsg().
The added documentation explains the introduced flags.

TIPC needs to have its endianess issues fixed. Unfortunately, the format of a
subscriber message is passed in directly from user space, so requiring this
message to be in network byte order breaks user space ABI. Revert this change
until such time as we can determine how to do this in a backwards compatible
manner.

Backout the tipc changes to the flags int he subscription message. These
changees, while reasonable on the surface, interefere with user space ABI
compatibility which is a no-no. This was part of the changes to fix the
endianess issues in the TIPC protocol, which would be really nice to do but we
need to do so in a way that is backwards compatible with user space.

__inet_inherit_port()
When __inet_inherit_port() is called on a tproxy connection the wrong locks are
held for the inet_bind_bucket it is added to. __inet_inherit_port() made an
implicit assumption that the listener's port number (and thus its bind bucket).
Unfortunately, if you're using the TPROXY target to redirect skbs to a
transparent proxy that assumption is not true anymore and things break.
This patch adds code to __inet_inherit_port() so that it can handle this case
by looking up or creating a new bind bucket for the child socket and updates
callers of __inet_inherit_port() to gracefully handle __inet_inherit_port()
failing.
Reported by and original patch from Stephen Buck <stephen.buck@exinda.com>.
