This commit eliminates the use of the link 'stale_limit' & 'prev_from'
(besides the already removed - 'stale_cnt') variables in the detection
of repeated retransmit failures as there is no proper way to initialize
them to avoid a false detection, i.e. it is not really a retransmission
failure but due to a garbage values in the variables.
Instead, a jiffies variable will be added to individual skbs (like the
way we restrict the skb retransmissions) in order to mark the first skb
retransmit time. Later on, at the next retransmissions, the timestamp
will be checked to see if the skb in the link transmq is "too stale",
that is, the link tolerance time has passed, so that a link reset will
be ordered. Note, just checking on the first skb in the queue is fine
enough since it must be the oldest one.
A counter is also added to keep track the actual skb retransmissions'
number for later checking when the failure happens.
The downside of this approach is that the skb->cb[] buffer is about to
be exhausted, however it is always able to allocate another memory area
and keep a reference to it when needed.

====================
rxrpc: Fix local endpoint handling
Here's a pair of patches that fix two issues in the handling of local
endpoints (rxrpc_local structs):
(1) Use list_replace_init() rather than list_replace() if we're going to
unconditionally delete the replaced item later, lest the list get
corrupted.
(2) Don't access the rxrpc_local object after passing our ref to the
workqueue, not even to illuminate tracepoints, as the work function
may cause the object to be freed. We have to cache the information
beforehand.

packet_sendmsg() checks tx_ring.pg_vec to decide
if it must call tpacket_snd().
Problem is that the check is lockless, meaning another thread
can issue a concurrent setsockopt(PACKET_TX_RING ) to flip
tx_ring.pg_vec back to NULL.
Given that tpacket_snd() grabs pg_vec_lock mutex, we can
perform the check again to solve the race.

====================
pull-request: can-next 2019-08-14
this is a pull request for net-next/master consisting of 41 patches.
The first two patches are for the kvaser_pciefd driver: Christer Beskow
removes unnecessary code in the kvaser_pciefd_pwm_stop() function,
YueHaibing removes the unused including of <linux/version.h>.
In the next patch YueHaibing also removes the unused including of
<linux/version.h> in the f81601 driver.
In the ti_hecc driver the next 6 patches are by me and fix checkpatch
warnings. YueHaibing's patch removes an unused variable in the
ti_hecc_mailbox_read() function.
The next 6 patches all target the xilinx_can driver. Anssi Hannula's
patch fixes a chip start failure with an invalid bus. The patch by
Venkatesh Yadav Abbarapu skips an error message in case of a deferred
probe. The 3 patches by Appana Durga Kedareswara rao fix the RX and TX
path for CAN-FD frames. Srinivas Neeli's patch fixes the bit timing
calculations for CAN-FD.
The next 12 patches are by me and several checkpatch warnings in the
af_can, raw and bcm components.
Thomas Gleixner provides a patch for the bcm, which switches the timer
to HRTIMER_MODE_SOFT and removes the hrtimer_tasklet.
Then 6 more patches by me for the gw component, which fix checkpatch
warnings, followed by 2 patches by Oliver Hartkopp to add CAN-FD
support.
The vcan driver gets 3 patches by me, fixing checkpatch warnings.
And finally a patch by Andre Hartmann to fix typos in CAN's netlink
header.

rxrpc_queue_local() attempts to queue the local endpoint it is given and
then, if successful, prints a trace line. The trace line includes the
current usage count - but we're not allowed to look at the local endpoint
at this point as we passed our ref on it to the workqueue.
Fix this by reading the usage count before queuing the work item.
Also fix the reading of local->debug_id for trace lines, which must be done
with the same consideration as reading the usage count.

When a local endpoint (struct rxrpc_local) ceases to be in use by any
AF_RXRPC sockets, it starts the process of being destroyed, but this
doesn't cause it to be removed from the namespace endpoint list immediately
as tearing it down isn't trivial and can't be done in softirq context, so
it gets deferred.
If a new socket comes along that wants to bind to the same endpoint, a new
rxrpc_local object will be allocated and rxrpc_lookup_local() will use
list_replace() to substitute the new one for the old.
Then, when the dying object gets to rxrpc_local_destroyer(), it is removed
unconditionally from whatever list it is on by calling list_del_init().
However, list_replace() doesn't reset the pointers in the replaced
list_head and so the list_del_init() will likely corrupt the local
endpoints list.
Fix this by using list_replace_init() instead.

TCP rst and fin packets do not qualify to place a flow into the
flowtable. Most likely there will be no more packets after connection
closure. Without this patch, this flow entry expires and connection
tracking picks up the entry in ESTABLISHED state using the fixup
timeout, which makes this look inconsistent to the user for a connection
that is actually already closed.

The following pull-request contains BPF updates for your *net-next* tree.
There is a small merge conflict in libbpf (Cc Andrii so he's in the loop

t = (struct btf_type *)btf__type_by_id(btf, i);

>>>>>>> 72ef80b5ee131e96172f19e74b4f98fa3404efe8
/* replace DATASEC with STRUCT */
Conflict is between the two commits 1d4126c4e119 ("libbpf: sanitize VAR to
conservative 1-byte INT") and b03bc6853c0e ("libbpf: convert libbpf code to
use new btf helpers"), so we need to pick the sanitation fixup as well as
use the new btf_is_datasec() helper and the whitespace cleanup. Looks like
the following:
[...]
if (!has_datasec && btf_is_var(t)) {
/* replace VAR with INT */
t->info = BTF_INFO_ENC(BTF_KIND_INT, 0, 0);
/*
* using size = 1 is the safest choice, 4 will be too
* big and cause kernel BTF validation failure if
* original variable took less than 4 bytes
*/
t->size = 1;
*(int *)(t + 1) = BTF_INT_ENC(0, 0, 8);
} else if (!has_datasec && btf_is_datasec(t)) {
/* replace DATASEC with STRUCT */
[...]
The main changes are:
1) Addition of core parts of compile once - run everywhere (co-re) effort,
that is, relocation of fields offsets in libbpf as well as exposure of
kernel's own BTF via sysfs and loading through libbpf, from Andrii.
More info on co-re: http://vger.kernel.org/bpfconf2019.html#session-2
and http://vger.kernel.org/lpc-bpf2018.html#session-2
2) Enable passing input flags to the BPF flow dissector to customize parsing
and allowing it to stop early similar to the C based one, from Stanislav.
3) Add a BPF helper function that allows generating SYN cookies from XDP and
tc BPF, from Petar.
4) Add devmap hash-based map type for more flexibility in device lookup for

5) Improvements to XDP forwarding sample code now utilizing recently enabled

6) Add support for reporting the effective cgroup progs in bpftool, from Jakub

7) Fix reading kernel config from bpftool via /proc/config.gz, from Peter.
8) Fix AF_XDP umem pages mapping for 32 bit architectures, from Ivan.
9) Follow-up to add two more BPF loop tests for the selftest suite, from Alexei.
10) Add perf event output helper also for other skb-based program types, from Allan.
11) Fix a co-re related compilation error in selftests, from Yonghong.

Change ct id hash calculation to only use invariants.
Currently the ct id hash calculation is based on some fields that can
change in the lifetime on a conntrack entry in some corner cases. The
current hash uses the whole tuple which contains an hlist pointer which
will change when the conntrack is placed on the dying list resulting in
a ct id change.
This patch also removes the reply-side tuple and extension pointer from
the hash calculation so that the ct id will will not change from
initialization until confirmation.

Introduce CAN FD support which needs an extension of the netlink API to
pass CAN FD type content to the kernel which has a different size to
Classic CAN. Additionally the struct canfd_frame has a new 'flags' element
that can now be modified with can-gw.
The new CGW_FLAGS_CAN_FD option flag defines whether the routing job
handles Classic CAN or CAN FD frames. This setting is very strict at
reception time and enables the new possibilities, e.g. CGW_FDMOD_* and
modifying the flags element of struct canfd_frame, only when
CGW_FLAGS_CAN_FD is set.

BUG: spinlock bad magic on CPU#2, swapper/0/1
lock: nf_connlabels_lock+0x0/0x60, .magic: 00000000, .owner: <none>/-1, .owner_cpu: 0
Call Trace:

Problem is that ct action init function can run before
connlabels_init(). Lock has not been initialised yet.
Fix it by using a static initialiser.
