4fa112f6b5 net: bcmgenet: Use BUG_ON instead of if condition followed by BUG
Use BUG_ON instead of if condition followed by BUG.

Something to notice in this particular case is that unlikely()
is already being called inside BUG_ON macro.

This issue was detected with the help of Coccinelle.

8aec4959d8 ip6_gre: update dst pmtu if dev mtu has been updated by toobig in __gre6_xmit
When receiving a Toobig icmpv6 packet, ip6gre_err would just set
tunnel dev's mtu, that's not enough. For skb_dst(skb)'s pmtu may
still be using the old value, it has no chance to be updated with
tunnel dev's mtu.

Jianlin found this issue by reducing route's mtu while running
netperf, the performance went to 0.

ip6ip6 and ip4ip6 tunnel can work well with this, as they lookup
the upper dst and update_pmtu it's pmtu or icmpv6_send a Toobig
to upper socket after setting tunnel dev's mtu.

We couldn't do that for ip6_gre, as gre's inner packet could be
any protocol, it's difficult to handle them (like lookup upper
dst) in a good way.

So this patch is to fix it by updating skb_dst(skb)'s pmtu when
dev->mtu < skb_dst(skb)'s pmtu in tx path. It's safe to do this
update there, as usually dev->mtu <= skb_dst(skb)'s pmtu and no
performance regression can be caused by this.

The similar fix in patch 'ipip: only increase err_count for some
certain type icmp in ipip_err' is needed for ip6gre_err.

In Jianlin's case, udp netperf broke even when receiving a TooBig

f3594f0a7e ipip: only increase err_count for some certain type icmp in ipip_err
t->err_count is used to count the link failure on tunnel and an err
will be reported to user socket in tx path if t->err_count is not 0.
udp socket could even return EHOSTUNREACH to users.

Since commit fd58156e45 ("IPIP: Use ip-tunneling code.") removed
the 'switch check' for icmp type in ipip_err(), err_count would be
increased by the icmp packet with ICMP_EXC_FRAGTIME code. an link
failure would be reported out due to this.

In Jianlin's case, when receiving ICMP_EXC_FRAGTIME a icmp packet,
udp netperf failed with the err:
  send_data: data send error: No route to host (errno 113)

We expect this error reported from tunnel to socket when receiving
some certain type icmp, but not ICMP_EXC_FRAGTIME, ICMP_SR_FAILED
or ICMP_PARAMETERPROB ones.

This patch is to bring 'switch check' for icmp type back to ipip_err
so that it only reports link failure for the right type icmp, just as
in ipgre_err() and ipip6_err().

123196b693 Merge branch 'dsa-lan9303-Learn-addresses-on-CPU-port-when-bridged'
Egil Hjelmeland says:

====================
net: dsa: lan9303: Learn addresses on CPU port when bridged

When CPU transmit directly to port using tag, the LAN9303 does not
learn MAC addresses received on the CPU port into the ALR table.
ALR learning is performed only when transmitting using ALR lookup.

Solution:
If the two external ports are bridged and the packet is not STP BPDU,
then use ALR lookup to allow ALR learning on CPU port.
Otherwise transmit directly to port with STP state override.

The first patch moves struct lan9303 to include/linux/dsa/lan9303.h in
order to prepare for the second patch.

Changes v1 -> v2:
 - new file: include/linux/dsa/lan9303.h instead of include/linux/lan9303.h
 - include linux/if_ether.h in include/linux/dsa/lan9303.h
 - renamed lan9303_tx_use_arl to lan9303_xmit_use_arl for consistency.
 - removed inline keyword to lan9303_xmit_use_arl

035226b964 bpf: remove tail_call and get_stackid helper declarations from bpf.h
commit afdb09c720 ("security: bpf: Add LSM hooks for bpf object related
syscall") included linux/bpf.h in linux/security.h. As a result, bpf
programs including bpf_helpers.h and some other header that ends up
pulling in also security.h, such as several examples under samples/bpf,
fail to compile because bpf_tail_call and bpf_get_stackid are now
"redefined as different kind of symbol".

>From bpf.h:

u64 bpf_tail_call(u64 ctx, u64 r2, u64 index, u64 r4, u64 r5);
u64 bpf_get_stackid(u64 r1, u64 r2, u64 r3, u64 r4, u64 r5);

Whereas in bpf_helpers.h they are:

static void (*bpf_tail_call)(void *ctx, void *map, int index);
static int (*bpf_get_stackid)(void *ctx, void *map, int flags);

Fix this by removing the unused declaration of bpf_tail_call and moving
the declaration of bpf_get_stackid in bpf_trace.c, which is the only
place where it's needed.

indicates that the liquidio watchdog kernel thread is running for this NIC.
Reason is:  it is incompatible with the firmware's use for SLI_SCRATCH_1.

In lieu of checking that now-deprecated flag, check the value of
oct_dev->adapter_refcount to determine whether or not to create the
watchdog kernel thread.

90edaac627 Revert "x86/mm: Limit mmap() of /dev/mem to valid physical addresses"
This reverts commit ce56a86e2a.

There's unanticipated interaction with some boot parameters like 'mem=',
which now cause the new checks via valid_mmap_phys_addr_range() to be too
restrictive, crashing a Qemu bootup in fact, as reported by Fengguang Wu.

So while the motivation of the change is still entirely valid, we
need a few more rounds of testing to get it right - it's way too late
after -rc6, so revert it for now.

4dc12ffeae l2tp: cleanup l2tp_tunnel_delete calls
l2tp_tunnel_delete does not return anything since commit 62b982eeb4
("l2tp: fix race condition in l2tp_tunnel_delete").  But call sites of
l2tp_tunnel_delete still do casts to void to avoid unused return value
warnings.

Kill these now useless casts.

c58320de51 drivers/net: arcnet: Convert timers to use timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to
