If adding a nexthop of an IPv6 multipath route fails, comment in
ip6_route_multipath() says we are going to delete all nexthops already
added. However, current implementation deletes even the routes it
hasn't even tried to add yet. For example, running
ip route add 1234:5678::/64 \
nexthop via fe80::aa dev dummy1 \
nexthop via fe80::bb dev dummy1 \
nexthop via fe80::cc dev dummy1
twice results in removing all routes first command added.
Limit the second (delete) run to nexthops that succeeded in the first
(add) run.

After sending the new data packets to probe (step 2), F-RTO may
incorrectly send more probes if the next ACK advances SND_UNA and
does not sack new packet. However F-RTO RFC 5682 probes at most
once. This bug may cause sender to always send new data instead of
repairing holes, inducing longer HoL blocking on the receiver for
the application.

Undo based on TCP timestamps should only happen on ACKs that advance
SND_UNA, according to the Eifel algorithm in RFC 3522:
Section 3.2:
(4) If the value of the Timestamp Echo Reply field of the
acceptable ACK's Timestamps option is smaller than the
value of RetransmitTS, then proceed to step (5),
Section Terminology:
We use the term 'acceptable ACK' as defined in [RFC793]. That is an
ACK that acknowledges previously unacknowledged data.
This is because upon receiving an out-of-order packet, the receiver
returns the last timestamp that advances RCV_NXT, not the current
timestamp of the packet in the DUPACK. Without checking the flag,
the DUPACK will cause tcp_packet_delayed() to return true and
tcp_try_undo_loss() will revert cwnd reduction.
Note that we check the condition in CA_Recovery already by only
calling tcp_try_undo_partial() if FLAG_SND_UNA_ADVANCED is set or
tcp_try_undo_recovery() if snd_una crosses high_seq.

Commit <5cf3d46192fc> ("udp: Simplify__udp*_lib_mcast_deliver")
simplified the filter for incoming IPv6 multicast but removed
the check of the local socket address and the UDP destination
address.
This patch restores the filter to prevent sockets bound to a IPv6
multicast IP to receive other UDP traffic link unicast.

By inspection, this appears to be a typo. The gating comparison
involves vxlan->dev rather than dev. In fact, dev is the iterator in
the preceding loop above but it is actually constant in the 2nd loop.
Use of dev seems to be a bad cut-n-paste from the prior call to
unregister_netdevice_queue. Change dev to vxlan->dev, since that is
what is actually being checked.

Before the patch, the command 'ip link add bond2 type bond mode 802.3ad'
causes the kernel to send a rtnl message for the bond2 interface, with an
ifindex 0.
'ip monitor' shows:
0: bond2: <BROADCAST,MULTICAST,MASTER> mtu 1500 state DOWN group default
link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
9: bond2@NONE: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN group default
link/ether ea:3e:1f:53:92:7b brd ff:ff:ff:ff:ff:ff
[snip]
The patch fixes the spotted bug by checking in bond driver if the interface
is registered before calling the notifier chain.
It also adds a check in rtmsg_ifinfo() to prevent this kind of bug in the
future.

We currently have no limit on the number of elements in a hash table.
This is a problem because some users (tipc) set a ceiling on the
maximum table size and when that is reached the hash table may
degenerate. Others may encounter OOM when growing and if we allow
insertions when that happens the hash table perofrmance may also
suffer.
This patch adds a new paramater insecure_max_entries which becomes
the cap on the table. If unset it defaults to max_size * 2. If
it is also zero it means that there is no cap on the number of
elements in the table. However, the table will grow whenever the
utilisation hits 100% and if that growth fails, you will get ENOMEM
on insertion.
As allowing oversubscription is potentially dangerous, the name
contains the word insecure.
Note that the cap is not a hard limit. This is done for performance
reasons as enforcing a hard limit will result in use of atomic ops
that are heavier than the ones we currently use.
The reasoning is that we're only guarding against a gross over-
subscription of the table, rather than a small breach of the limit.

If phy_start_aneg() was called while the phydev is in the PHY_RESUMING
state, then its state would immediately transition to PHY_AN (or
PHY_FORCING). This meant the phy_state_machine() never processed the
PHY_RESUMING state change, which meant interrupts weren't enabled for the
PHY. If the PHY used low-power mode (i.e. using BMCR_PDOWN), then the
physical link wouldn't get powered up again.
There seems no point for phy_start_aneg() to make the PHY_RESUMING -->
PHY_AN transition, as the state machine will do this anyway. I'm not sure
about the case where autoneg is disabled, as my patch will change
behaviour so that the PHY goes to PHY_NOLINK instead of PHY_FORCING. An
alternative solution would be to move the phy_config_interrupt() and
phy_resume() work out of the state machine and into phy_start().
The background behind this: we're running linux v3.16.7 and from user-space
we want to enable the eth port (i.e. do a SIOCSIFFLAGS ioctl with the
IFF_UP flag) and immediately afterward set the interface's speed/duplex.
Enabling the interface calls .ndo_open() then phy_start() and the PHY
transitions PHY_HALTED --> PHY_RESUMING. Setting the speed/duplex ends up
calling phy_ethtool_sset(), which calls phy_start_aneg() (meanwhile the
phy_state_machine() hasn't processed the PHY_RESUMING state change yet).

The commit c5adde9468b0714a051eac7f9666f23eb10b61f7 ("netlink:
eliminate nl_sk_hash_lock") breaks the autobind retry mechanism
because it doesn't reset portid after a failed netlink_insert.
This means that should autobind fail the first time around, then
the socket will be stuck in limbo as it can never be bound again
since it already has a non-zero portid.

RGMII interfaces come in multiple flavors: RGMII with transmit or
receive internal delay, no delays at all, or delays in both direction.
This change extends the initial check for PHY_INTERFACE_MODE_RGMII to
cover all of these variants since EEE should be allowed for any of these
modes, since it is a property of the RGMII, hence Gigabit PHY capability
more than the RGMII electrical interface and its delays.

Once we get a neighbour through looking up arp cache or creating a

already taken. But as we don't put the refcount again after it's

In compliance with RFC5961, the network stack send challenge ACK in
response to spurious SYN packets, since commit 0c228e833c88 ("tcp:
Restore RFC5961-compliant behavior for SYN packets").
This pose a problem for netfilter conntrack in state LAST_ACK, because
this challenge ACK is (falsely) seen as ACKing last FIN, causing a
false state transition (into TIME_WAIT).
The challenge ACK is hard to distinguish from real last ACK. Thus,
solution introduce a flag that tracks the potential for seeing a
challenge ACK, in case a SYN packet is let through and current state
is LAST_ACK.
When conntrack transition LAST_ACK to TIME_WAIT happens, this flag is
used for determining if we are expecting a challenge ACK.

With a cross-compiler based on gcc-4.9, I see warnings like the following:
drivers/net/ethernet/mellanox/mlx4/resource_tracker.c: In function 'mlx4_SW2HW_CQ_wrapper':
drivers/net/ethernet/mellanox/mlx4/resource_tracker.c:3048:10: error: 'cq' may be used uninitialized in this function [-Werror=maybe-uninitialized]
cq->mtt = mtt;
I think the warning is spurious because we only use cq when
cq_res_start_move_to() returns zero, and it always initializes *cq in that
case. The srq case is similar. But maybe gcc isn't smart enough to figure
that out.
Initialize cq and srq explicitly to avoid the warnings.

It was reported that trancerout6 would cause
a kernel to crash when trying to compute checksums
on raw UDP packets. The cause was the check in
__ip6_append_data that would attempt to use
partial checksums on the packet. However,
raw sockets do not initialize partial checksum
fields so partial checksums can't be used.
Solve this the same way IPv4 does it. raw sockets
pass transhdrlen value of 0 to ip_append_data which
causes the checksum to be computed in software. Use
the same check in ip6_append_data (check transhdrlen).

If nl_table is sharing one cache line with one of them, netlink
performance is really bad on SMP.

Currently vlan notifier handler will try to update all vlans
for a device when that device comes up. A problem occurs,
however, when the vlan device was set to promiscuous, but not
by the user (ex: a bridge). In that case, dev->gflags are
not updated. What results is that the lower device ends
up with an extra promiscuity count. Here are the
backtraces that prove this:
[62852.052179] [<ffffffff814fe248>] __dev_set_promiscuity+0x38/0x1e0
[62852.052186] [<ffffffff8160bcbb>] ? _raw_spin_unlock_bh+0x1b/0x40

[62852.052190] [<ffffffff814fe694>] dev_set_promiscuity+0x24/0x50
[62852.052194] [<ffffffffa0324795>] vlan_dev_open+0xd5/0x1f0 [8021q]
[62852.052196] [<ffffffff814fe58f>] __dev_open+0xbf/0x140
[62852.052198] [<ffffffff814fe88d>] __dev_change_flags+0x9d/0x170
[62852.052200] [<ffffffff814fe989>] dev_change_flags+0x29/0x60
The above comes from the setting the vlan device to IFF_UP state.
[62852.053569] [<ffffffff814fe248>] __dev_set_promiscuity+0x38/0x1e0
[62852.053571] [<ffffffffa032459b>] ? vlan_dev_set_rx_mode+0x2b/0x30
[8021q]
[62852.053573] [<ffffffff814fe8d5>] __dev_change_flags+0xe5/0x170
[62852.053645] [<ffffffff814fe989>] dev_change_flags+0x29/0x60
[62852.053647] [<ffffffffa032334a>] vlan_device_event+0x18a/0x690
[8021q]
[62852.053649] [<ffffffff8161036c>] notifier_call_chain+0x4c/0x70
[62852.053651] [<ffffffff8109d456>] raw_notifier_call_chain+0x16/0x20
[62852.053653] [<ffffffff814f744d>] call_netdevice_notifiers+0x2d/0x60
[62852.053654] [<ffffffff814fe1a3>] __dev_notify_flags+0x33/0xa0
[62852.053656] [<ffffffff814fe9b2>] dev_change_flags+0x52/0x60
[62852.053657] [<ffffffff8150cd57>] do_setlink+0x397/0xa40
And this one comes from the notification code. What we end
up with is a vlan with promiscuity count of 1 and and a physical
device with a promiscuity count of 2. They should both have
a count 1.
To resolve this issue, vlan code can use dev_get_flags() api
which correctly masks promiscuity and allmulti flags.

Don't do clock-mode-select if clk == NULL,
since when building without CONFIG_HAVE_CLK,
clk_get returns NULL and clk_get_rate returns 0.
Doing clock-mode-select in this cause causes kszphy_probe to
return -EINVAL and thus prevents the device from being probed.
The original code (before regression) would return 0
when building without CONFIG_HAVE_CLK.

Commit d4988623cc60 ("IB/qib: use arch_phys_wc_add()")
adjusted mtrr inititialization to use the new interface.
Unfortunately, the new interface returns a signed
value and the patch tested the unsigned wc_cookie.
Fix the issue by changing the type of wc_cookie to int. For
the success case the ret left at zero to avoid
a warning from the caller. For failure wc_cookie
is used as the ret.

Commit 46490b572544 ("MIPS: kernel: elf: Improve the overall ABI and FPU
mode checks") reworked the ELF FP ABI mode selection logic, but when
CONFIG_MIPS_O32_FP64_SUPPORT is enabled it breaks the use of binaries
which have no PT_MIPS_ABIFLAGS program header & associated
.MIPS.abiflags section.
A default mode is selected based upon whether the ELF contains MIPS32 or
MIPS64 code, but that selection is made in arch_elf_pt_proc.
arch_elf_pt_proc only executes when a PT_MIPS_ABIFLAGS program header is
found. If one is not found then arch_elf_pt_proc is never called, and no
default overall_fp_mode value is selected. When arch_check_elf is
called, both abi0 & abi1 are MIPS_ABI_FP_UNKNOWN which leads to both
prog_req & interp_req being set to none_req. none_req matches none of
the conditions for mode selection at the end of arch_check_elf, so
overall_fp_mode is left untouched. Finally once mips_set_personality_fp
is called the BUG() in the default case is then hit & the kernel likely
panics.
Fix this by moving the selection of a default overall mode to the start
of arch_check_elf, which runs once per ELF executed regardless of
whether it has a PT_MIPS_ABIFLAGS program header.

For listening endpoints bound to the wildcard address, we need to pass
the wildcard address mapping to iwpm_get_remote_info() instead of the
mapped address of the new child connection.
Without this fix, and with iwarp port mapping enabled, each iw_cxgb4
connection that is spawned from a listening endpoint bound to the wildcard
address, will generate an annoying dmesg entry about failing to find
the remote address mapping info, and the connection state displayed in
debugfs under /sys/kernel/debug/iw_cxgb4/<pci-slot-no>/eps will not have
the peer's address/port mapping info. The connection still works though.
