Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for your
net-next tree:
1) Free hooks via call_rcu to speed up netns release path, from
Florian Westphal.
2) Reduce memory footprint of hook arrays, skip allocation if family is
not present - useful in case decnet support is not compiled built-in.
Patches from Florian Westphal.
3) Remove defensive check for malformed IPv4 - including ihl field - and
IPv6 headers in x_tables and nf_tables.
4) Add generic flow table offload infrastructure for nf_tables, this
includes the netlink control plane and support for IPv4, IPv6 and
mixed IPv4/IPv6 dataplanes. This comes with NAT support too. This
patchset adds the IPS_OFFLOAD conntrack status bit to indicate that
this flow has been offloaded.
5) Add secpath matching support for nf_tables, from Florian.
6) Save some code bytes in the fast path for the nf_tables netdev,
bridge and inet families.
7) Allow one single NAT hook per point and do not allow to register NAT
hooks in nf_tables before the conntrack hook, patches from Florian.
8) Seven patches to remove the struct nf_af_info abstraction, instead
we perform direct calls for IPv4 which is faster. IPv6 indirections
are still needed to avoid dependencies with the 'ipv6' module, but
these now reside in struct nf_ipv6_ops.
9) Seven patches to handle NFPROTO_INET from the Netfilter core,
hence we can remove specific code in nf_tables to handle this
pseudofamily.
10) No need for synchronize_net() call for nf_queue after conversion
to hook arrays. Also from Florian.
11) Call cond_resched_rcu() when dumping large sets in ipset to avoid
softlockup. Again from Florian.
12) Pass lockdep_nfnl_is_held() to rcu_dereference_protected(), patch
from Florian Westphal.
13) Fix matching of counters in ipset, from Jozsef Kadlecsik.
14) Missing nfnl lock protection in the ip_set_net_exit path, also
from Jozsef.
15) Move connlimit code that we can reuse from nf_tables into
nf_conncount, from Florian Westhal.
And asorted cleanups:
16) Get rid of nft_dereference(), it only has one single caller.
17) Add nft_set_is_anonymous() helper function.
18) Remove NF_ARP_FORWARD leftover chain definition in nf_tables_arp.
19) Remove unnecessary comments in nf_conntrack_h323_asn1.c
From Varsha Rao.
20) Remove useless parameters in frag_safe_skb_hp(), from Gao Feng.
21) Constify layer 4 conntrack protocol definitions, function
parameters to register/unregister these protocol trackers, and
timeouts. Patches from Florian Westphal.
22) Remove nlattr_size indirection, from Florian Westphal.
23) Add fall-through comments as -Wimplicit-fallthrough needs this,
from Gustavo A. R. Silva.
24) Use swap() macro to exchange values in ipset, patch from
Gustavo A. R. Silva.

Under speculation, CPUs may mis-predict branches in bounds checks. Thus,
memory accesses under a bounds check may be speculated even if the
bounds check fails, providing a primitive for building a side channel.
To avoid leaking kernel data round up array-based maps and mask the index
after bounds check, so speculated load with out of bounds index will load
either valid value from the array or zero from the padded area.
Unconditionally mask index for all array types even when max_entries
are not rounded to power of 2 for root user.
When map is created by unpriv user generate a sequence of bpf insns
that includes AND operation to make sure that JITed code includes
the same 'index & index_mask' operation.
If prog_array map is created by unpriv user replace
bpf_tail_call(ctx, map, index);
with
if (index >= max_entries) {
index &= map->index_mask;
bpf_tail_call(ctx, map, index);
}
(along with roundup to power 2) to prevent out-of-bounds speculation.
There is secondary redundant 'if (index >= max_entries)' in the interpreter
and in all JITs, but they can be optimized later if necessary.
Other array-like maps (cpumap, devmap, sockmap, perf_event_array, cgroup_array)
cannot be used by unpriv, so no changes there.
That fixes bpf side of "Variant 1: bounds check bypass (CVE-2017-5753)" on
all architectures with and without JIT.

Commit 7d06d5895c ("Revert "Bluetooth: btusb: fix QCA...suspend/resume"")
removed the setting of the BTUSB_RESET_RESUME quirk for QCA Rome devices,
instead favoring adding USB_QUIRK_RESET_RESUME quirks in usb/core/quirks.c.
This was done because the DIY BTUSB_RESET_RESUME reset-resume handling
has several issues (see the original commit message). An added advantage
of moving over to the USB-core reset-resume handling is that it also
disables autosuspend for these devices, which is similarly broken on these.
But there are 2 issues with this approach:
1) It leaves the broken DIY BTUSB_RESET_RESUME code in place for Realtek
devices.
2) Sofar only 2 of the 10 QCA devices known to the btusb code have been
added to usb/core/quirks.c and if we fix the Realtek case the same way
we need to add an additional 14 entries. So in essence we need to
duplicate a large part of the usb_device_id table in btusb.c in
usb/core/quirks.c and manually keep them in sync.
This commit instead restores setting a reset-resume quirk for QCA devices
in the btusb.c code, avoiding the duplicate usb_device_id table problem.
This commit avoids the problems with the original DIY BTUSB_RESET_RESUME
code by simply setting the USB_QUIRK_RESET_RESUME quirk directly on the
usb_device.
This commit also moves the BTUSB_REALTEK case over to directly setting the
USB_QUIRK_RESET_RESUME on the usb_device and removes the now unused
BTUSB_RESET_RESUME code.

SCTP PMTU discovery fixes

syzbot reported a hang involving SCTP, on which it kept flooding dmesg
with the message:
[ 246.742374] sctp: sctp_transport_update_pmtu: Reported pmtu 508 too
low, using default minimum of 512
That happened because whenever SCTP hits an ICMP Frag Needed, it tries
to adjust to the new MTU and triggers an immediate retransmission. But
it didn't consider the fact that MTUs smaller than the SCTP minimum MTU
allowed (512) would not cause the PMTU to change, and issued the
retransmission anyway (thus leading to another ICMP Frag Needed, and so
on).
As IPv4 (ip_rt_min_pmtu=556) and IPv6 (IPV6_MIN_MTU=1280) minimum MTU
are higher than that, sctp_transport_update_pmtu() is changed to
re-fetch the PMTU that got set after our request, and with that, detect
if there was an actual change or not.
The fix, thus, skips the immediate retransmission if the received ICMP
resulted in no change, in the hope that SCTP will select another path.
Note: The value being used for the minimum MTU (512,
SCTP_DEFAULT_MINSEGMENT) is not right and instead it should be (576,
SCTP_MIN_PMTU), but such change belongs to another patch.
Changes from v1:
- do not disable PMTU discovery, in the light of commit
06ad391919 ("[SCTP] Don't disable PMTU discovery when mtu is small")
and as suggested by Xin Long.
- changed the way to break the rtx loop by detecting if the icmp
resulted in a change or not

Currently, if PMTU discovery is disabled on a given transport, but the
configured value is higher than the actual PMTU, it is likely that we
will get some icmp Frag Needed. The issue is, if PMTU discovery is
disabled, we won't update the information and will issue a
retransmission immediately, which may very well trigger another ICMP,
and another retransmission, leading to a loop.
The fix is to simply not trigger immediate retransmissions if PMTU
discovery is disabled on the given transport.

However, the user doesn't always create max_vfs. So, the check should be
against the created number of VFs. The number of bnxt_vf_info structures
that are allocated in bnxt_alloc_vf_resources routine is the "number of
requested VFs". So, if an "invalid VF id" falls between the requested
number of VFs and the max_vfs, the driver will be dereferencing an invalid

Update the HNS3_NIC_STATE_DOWN bit when NIC state changes.
When NIC is down, mask the packet statistics for querying
with ifconfig command. It's a common practice.

It takes more than 200 query response messages between
driver and IMP, while updating the packet statistics.
It's too heavy for IMP to update it per second.
Extend the update period of packet statistics data from
1 second to 300 seconds(if too long, the statistics may
overflow).
As a result, we need to update it while querying with
ifconfig tool to keep the statistics data fresh.

The igu_rx_err_pkt indicates the same error with
mac_rx_fcs_err_pkt_num, so remove it.

Some members of packet statistics are named in different styles.
This patch unifies them with new internal name rules, the main
modification are below:
trans --> tx
rcv --> rx
rcb_q%d_tx --> txq#%d
rcb_q%d_rx --> rxq#%d
sw_err_cnt(tx side) --> tx_dropped
sw_err_cnt(rx side) --> rx_dropped
pkts --> packets
tx_err_cnt --> errors
rx_err_cnt --> errors

Rxvlan offload status can only be changed by PF. Initialize
the value of NETIF_F_HW_VLAN_CTAG_RX bit of hw_features for
VFS to false, make sure user can't be able to change it.
