Since a pseudo-random starting point is used in finding a port in
the default case, that 'else if' branch above is no longer a necessity.
So remove it to simplify code.

To make overflows as obvious as possible and to prevent code from blithely
proceeding with a truncated string. This also has a side-effect to fix a

This is a leftover from days where single-cpu systems were common:
Store last port used to resolve a clash to use it as a starting point when
the next conflict needs to be resolved.
When we have parallel attempt to connect to same address:port pair,
its likely that both cores end up computing the same "available" port,
as both use same starting port, and newly used ports won't become
visible to other cores until the conntrack gets confirmed later.
One of the cores then has to drop the packet at insertion time because
the chosen new tuple turns out to be in use after all.
Lets simplify this: remove port rover and use a pseudo-random starting
point.
Note that this doesn't make netfilter default to 'fully random' mode;
the 'rover' was only used if NAT could not reuse source port as-is.

Now that call_rcu()'s callback is not invoked until after bh-disable
regions of code have completed (in addition to explicitly marked
RCU read-side critical sections), call_rcu() can be used in place
of call_rcu_bh(). Similarly, rcu_barrier() can be used in place of
rcu_barrier_bh() and synchronize_rcu() in place of synchronize_rcu_bh().
This commit therefore makes these changes.

nf_flow_offload_gc_step() and nf_flow_table_iterate() are very similar.
so that many duplicate code can be removed.
After this patch, nf_flow_offload_gc_step() is simple callback function of
nf_flow_table_iterate() like nf_flow_table_do_cleanup().

Useful to only set a particular range of the conntrack mark while
leaving existing parts of the value alone, e.g. when updating
conntrack marks via netlink from userspace.
For NFQUEUE it was already implemented in commit 534473c6080e
("netfilter: ctnetlink: honor CTA_MARK_MASK when setting ctmark").
This now adds the same functionality also for the other netlink
conntrack mark changes.

Jozsef Kadlecsik says:
====================
- Introduction of new commands and thus protocol version 7. The
new commands makes possible to eliminate the getsockopt interface
of ipset and use solely netlink to communicate with the kernel.
Due to the strict attribute checking both in user/kernel space,
a new protocol number was introduced. Both the kernel/userspace is
fully backward compatible.
- Make invalid MAC address checks consisten, from Stefano Brivio.
The patch depends on the next one.
- Allow matching on destination MAC address for mac and ipmac sets,
also from Stefano Brivio.

Two new commands (IPSET_CMD_GET_BYNAME, IPSET_CMD_GET_BYINDEX) are
introduced. The new commands makes possible to eliminate the getsockopt
operation (in iptables set/SET match/target) and thus use only netlink
communication between userspace and kernel for ipset. With the new
protocol version, userspace can exactly know which functionality is
supported by the running kernel.
Both the kernel and userspace is fully backward compatible.

Set types bitmap:ipmac and hash:ipmac check that MAC addresses
are not all zeroes.
Introduce one missing check, and make the remaining ones
consistent, using is_zero_ether_addr() instead of comparing
against an array containing zeroes.
This was already done for hash:mac sets in commit 26c97c5d8dac
("netfilter: ipset: Use is_zero_ether_addr instead of static and
memcmp").

ipmac sets
There doesn't seem to be any reason to restrict MAC address
matching to source MAC addresses in set types bitmap:ipmac,
hash:ipmac and hash:mac. With this patch, and this setup:
ip netns add A
ip link add veth1 type veth peer name veth2 netns A
ip addr add 192.0.2.1/24 dev veth1
ip -net A addr add 192.0.2.2/24 dev veth2
ip link set veth1 up
ip -net A link set veth2 up
ip netns exec A ipset create test hash:mac
dst=$(ip netns exec A cat /sys/class/net/veth2/address)
ip netns exec A ipset add test ${dst}
ip netns exec A iptables -P INPUT DROP
ip netns exec A iptables -I INPUT -m set --match-set test dst -j ACCEPT
ipset will match packets based on destination MAC address:
# ping -c1 192.0.2.2 >/dev/null
# echo $?
0

The mv88e6161 would sometime fail to probe with a timeout waiting for
the switch to complete an operation. This operation is supposed to
clear the statistics counters. However, due to a read/modify/write,
without the needed mask, the operation actually carried out was more
random, with invalid parameters, resulting in the switch not
responding. We need to preserve the histogram mode bits, so apply a
mask to keep them.

When a link failure is detected locally, the link is reset, the flag
link->in_session is set to false, and a RESET_MSG with the 'stopping'
bit set is sent to the peer.
The purpose of this bit is to inform the peer that this endpoint just
is going down, and that the peer should handle the reception of this
particular RESET message as a local failure. This forces the peer to
accept another RESET or ACTIVATE message from this endpoint before it
can re-establish the link. This again is necessary to ensure that
link session numbers are properly exchanged before the link comes up
again.
If a failure is detected locally at the same time at the peer endpoint
this will do the same, which is also a correct behavior.
However, when receiving such messages, the endpoints will not
distinguish between 'stopping' RESETs and ordinary ones when it comes
to updating session numbers. Both endpoints will copy the received
session number and set their 'in_session' flags to true at the
reception, while they are still expecting another RESET from the
peer before they can go ahead and re-establish. This is contradictory,
since, after applying the validation check referred to below, the
'in_session' flag will cause rejection of all such messages, and the
link will never come up again.
We now fix this by not only handling received RESET/STOPPING messages
as a local failure, but also by omitting to set a new session number
and the 'in_session' flag in such cases.

Only first fragment has the sport/dport information,
not the following ones.
If we want consistent hash for all fragments, we need to
ignore ports even for first fragment.
This bug is visible for IPv6 traffic, if incoming fragments
do not have a flow label, since skb_get_hash() will give
different results for first fragment and following ones.
It is also visible if any routing rule wants dissection
and sport or dport.
See commit 5e5d6fed3741 ("ipv6: route: dissect flow
in input path if fib rules need it") for details.
[edumazet] rewrote the changelog completely.

IOMMU fault may occurr on unbind/bind or if_down/if_up sequence.
Although driver disables the rings on down, this is not enough.
Due to internal HW design, during subsequent initialization
NIC sometimes may reuse RX descriptors cache and write to the
host memory from the descriptor cache.
That's get catched by IOMMU on host.
This patch invalidates the descriptor cache in NIC on interface down
to prevent writing to the cached descriptors and to the memory pointed
in those descriptors.

Flow control statuses were not synchronized between blocks,
that caused packets/link drop on some corner cases, when
MAC sent PFC although Phy was not expecting these to come.
Driver should readout the negotiated FC from phy and
configure RX block accordigly.
This is done on each link change event with information from FW.

The commit f77f0aee4da4 ("net: use core MTU range checking in USB NIC
drivers") introduce a common MTU handling for usbnet. But it's missing
the necessary changes for smsc95xx. So set the MTU range accordingly.
This patch has been tested on a Raspberry Pi 3.

When there are no SPQ entries left in the free_pool, new entries are
allocated and are added to the unlimited list. When an entry in the pool
is available, the content is copied from the original entry, and the new
entry is sent to the device. qed_spq_post() is not aware of that, so the
additional entry is stored in the original entry as p_post_ent, which can
later be returned to the pool.

Intel Wired LAN Driver Updates 2018-11-07
This series contains fixes to igb, i40e and ice drivers.
Anirudh fixes an issue during rebuild of the ice driver, where we need
to set the carrier state, as well as start or stop the queues all based
on the link status. Removed functions that were duplicating current
functionality in the VSI rebuild/replay framework.
Dave fixes a potential resource collision during the remove path, so add
a check to see if we are in the middle of a reset. Fixed the remove
path to ensure we call netif_napi_del() to free vectors before we set
vsi->netdev to NULL.
Akeem fixes an issue when the receive or transmit pause parameter is
set, results in link loss on the interface. Fixed the spelling of
"Enabling" in error message.
Victor fixes potential memory leak by also freeing the related VSI
contexts in the unload path.
Md Fahad fixes a flag during port VLAN insertion, which was not being
set properly.
Brett fixes a transmit timeout during stress due to the hardware tail
and software tail were incorrectly out of sync.
Miroslav Lichvar fixes the igb PHC timecounter update interval to be
sure the timecounter is updated in time.
Chinh fixes the req_speeds variable to be u16 instead of u8 so that it
can handle all the link speeds.
Jake fixes i40e to add back the missing feature flags, which was causing
IP-in-IP offloads to be reported as not supported.

The assignment of the feature flag NETIF_F_NTUPLE and NETIF_F_HW_TC
occurs prior to the initial setup of the local hw_features variable.
This means the features are set as user-changeable, but are not set in
the currently active feature list. This results in the features being
disabled at the driver's initial load.
Move the assignment after the initial assignment of hw_features, and
assign to the local variable. This ensures that NETIF_F_NTUPLE and
NETIF_F_HW_TC are marked as user-changeable, and also enables them by
default when the driver loads.

Since commit bacd75cfac8a ("i40e/i40evf: Add capability exchange for
outer checksum", 2017-04-06) the i40e driver has not reported support
for IP-in-IP offloads. This likely occurred due to a bad rebase, as the
commit extracts hw_enc_features into its own variable. As part of this
change, it dropped the NETIF_F_FSO_IPXIP flags from the
netdev->hw_enc_features. This was unfortunately not caught during code
review.
Fix this by adding back the missing feature flags.
For reference, NETIF_F_GSO_IPXIP4 was added in commit 7e13318daa4a
("net: define gso types for IPx over IPv4 and IPv6", 2016-05-20),
replacing NETIF_F_GSO_IPIP and NETIF_F_GSO_SIT.
NETIF_F_GSO_IPXIP6 was added in commit bf2d1df39502 ("intel: Add support
