commit 9807b4d949 upstream.
Right now the Makefile for the mpt3sas driver does not even allow the
driver to be built into the kernel. So fix that up, as there doesn't
seem to be any obvious reason why this shouldn't be done.

Bug 60747 - 1286:2044 [Microsoft Surface Pro]
Marvell 88W8797 wifi show 3 interface under network
https://bugzilla.kernel.org/show_bug.cgi?id=60747
This issue was also reported previously by OLPC and some folks from
the community.
There are 3 network interfaces with different types being created
when mwifiex driver is loaded:
1. mlan0 (infra. STA)
2. uap0 (AP)
3. p2p0 (P2P_CLIENT)
The Network Manager attempts to use all 3 interfaces above without
filtering the managed interface type. As the result, 3 identical
interfaces are displayed under network manager. If user happens to
click on an entry under which its interface is uap0 or p2p0, the
association will fail.
Work around it by removing the creation of AP and P2P interfaces
at driver loading time. These interfaces can be added with 'iw' or
other applications manually when they are needed.

[ Upstream commit 7140860291 ]
This commit fixes a long-standing bug that has been reported by many
users: on some Armada 370 platforms, only the network interface that
has been used in U-Boot to tftp the kernel works properly in
Linux. The other network interfaces can see a 'link up', but are
unable to transmit data. The reports were generally made on the Armada
370-based Mirabox, but have also been given on the Armada 370-RD
board.
The network MAC in the Armada 370/XP (supported by the mvneta driver
in Linux) has a functionality that allows it to continuously poll the
PHY and directly update the MAC configuration accordingly (speed,
duplex, etc.). The very first versions of the driver submitted for
review were using this hardware mechanism, but due to this, the driver
was not integrated with the kernel phylib. Following reviews, the
driver was changed to use the phylib, and therefore a software based
polling. In software based polling, Linux regularly talks to the PHY
over the MDIO bus, and sees if the link status has changed. If it's
the case then the adjust_link() callback of the driver is called to
update the MAC configuration accordingly.
However, it turns out that the adjust_link() callback was not
configuring the hardware in a completely correct way: while it was
setting the speed and duplex bits correctly, it wasn't telling the
hardware to actually take into account those bits rather than what the
hardware-based PHY polling mechanism has concluded. So, in fact the
adjust_link() callback was basically a no-op.
However, the network happened to be working because on the network
interfaces used by U-Boot for tftp on Armada 370 platforms because the
hardware PHY polling was enabled by the bootloader, and left enabled
by Linux. However, the second network interface not used for tftp (or
both network interfaces if the kernel is loaded from USB, NAND or SD
card) didn't had the hardware PHY polling enabled.
This patch fixes this situation by:
(1) Making sure that the hardware PHY polling is disabled by clearing
the MVNETA_PHY_POLLING_ENABLE bit in the MVNETA_UNIT_CONTROL
register in the driver ->probe() function.
(2) Making sure that the duplex and speed selections made by the
adjust_link() callback are taken into account by clearing the
MVNETA_GMAC_AN_SPEED_EN and MVNETA_GMAC_AN_DUPLEX_EN bits in the
MVNETA_GMAC_AUTONEG_CONFIG register.
This patch has been tested on Armada 370 Mirabox, and now both network
interfaces are usable after boot.

In tcp_v6_do_rcv() code, when processing pkt options, we soley work
on our skb clone opt_skb that we've created earlier before entering
tcp_rcv_established() on our way. However, only in condition ...
if (np->rxopt.bits.rxtclass)
np->rcv_tclass = ipv6_get_dsfield(ipv6_hdr(skb));
... we work on skb itself. As we extract every other information out
of opt_skb in ipv6_pktoptions path, this seems wrong, since skb can
already be released by tcp_rcv_established() earlier on. When we try
to access it in ipv6_hdr(), we will dereference freed skb.

to EPROTO.

"Codes 5 and 6 are more informative subsets of code 1."

commit 8728c544a9 ("net: dev_pick_tx() fix") and commit
b6fe83e952 ("bonding: refine IFF_XMIT_DST_RELEASE capability")
are quite incompatible : Queue selection is disabled because skb
dst was dropped before entering bonding device.
This causes major performance regression, mainly because TCP packets
for a given flow can be sent to multiple queues.
This is particularly visible when using the new FQ packet scheduler
with MQ + FQ setup on the slaves.

Should a connect fail, if the publication/server is unavailable or
due to some other error, a positive value will be returned and errno
is never set. If the application code checks for an explicit zero
return from connect (success) or a negative return (failure), it
will not catch the error and subsequent send() calls will fail as
shown from the strace snippet below.
socket(0x1e /* PF_??? */, SOCK_SEQPACKET, 0) = 3
connect(3, {sa_family=0x1e /* AF_??? */, sa_data="\2\1\322\4\0\0\322\4\0\0\0\0\0\0"}, 16) = 111

[ Upstream commit 25a6e6b84f ]
Allocating skbs when sending out neighbour discovery messages
currently uses sock_alloc_send_skb() based on a per net namespace
socket and thus share a socket wmem buffer space.
If a netdevice is temporarily unable to transmit due to carrier
loss or for other reasons, the queued up ndisc messages will cosnume
all of the wmem space and will thus prevent from any more skbs to
be allocated even for netdevices that are able to transmit packets.
The number of neighbour discovery messages sent is very limited,
use of alloc_skb() bypasses the socket wmem buffer size enforcement
while the manual call to skb_set_owner_w() maintains the socket
reference needed for the IPv6 output path.
This patch has orginally been posted by Eric Dumazet in a modified

The zero value means that tsecr is not valid, so it's a special case.
tsoffset is used to customize tcp_time_stamp for one socket.
tsoffset is usually zero, it's used when a socket was moved from one
host to another host.
Currently this issue affects logic of tcp_rcv_rtt_measure_ts. Due to
incorrect value of rcv_tsecr, tcp_rcv_rtt_measure_ts sets rto to
TCP_RTO_MAX.

commit 56b765b79 ("htb: improved accuracy at high rates")
broke the "linklayer atm" handling.
tc class add ... htb rate X ceil Y linklayer atm
The linklayer setting is implemented by modifying the rate table
which is send to the kernel. No direct parameter were
transferred to the kernel indicating the linklayer setting.
The commit 56b765b79 ("htb: improved accuracy at high rates")
removed the use of the rate table system.
To keep compatible with older iproute2 utils, this patch detects
the linklayer by parsing the rate table. It also supports future
versions of iproute2 to send this linklayer parameter to the
kernel directly. This is done by using the __reserved field in
struct tc_ratespec, to convey the choosen linklayer option, but
only using the lower 4 bits of this field.
Linklayer detection is limited to speeds below 100Mbit/s, because
at high rates the rtab is gets too inaccurate, so bad that
several fields contain the same values, this resembling the ATM
detect. Fields even start to contain "0" time to send, e.g. at
1000Mbit/s sending a 96 bytes packet cost "0", thus the rtab have
been more broken than we first realized.
