The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

In case of error, the function pci_create_slot() returns ERR_PTR() and
never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR().

The backend handling for /proc/net/if_inet6 in addrconf.c doesn't properly
handle starting/stopping the iteration. The problem is that at some point
during the iteration, an overflow is detected and the process is
subsequently stopped. The item being shown via seq_printf() when the
overflow occurs is not actually shown, though. When start() is
subsequently called to resume iterating, it returns the next item, and
thus the item that was being processed when the overflow occurred never
gets printed.
Alter the meaning of the private data member "offset". Currently, when it
is not 0 (which only happens at the very beginning), "offset" represents
the next hlist item to be printed. After this change, "offset" always
represents the current item.
This is also consistent with the private data member "bucket", which
represents the current bucket, and also the use of "pos" as defined in
seq_file.txt:
The pos passed to start() will always be either zero, or the most
recent pos used in the previous session.

netlbl_unlabel_addrinfo_get() assumes that if it finds the
NLBL_UNLABEL_A_IPV4ADDR attribute, it must also have the
NLBL_UNLABEL_A_IPV4MASK attribute as well. However, this is
not necessarily the case as the current checks in
netlbl_unlabel_staticadd() and friends are not sufficent to
enforce this.
If passed a netlink message with NLBL_UNLABEL_A_IPV4ADDR,
NLBL_UNLABEL_A_IPV6ADDR, and NLBL_UNLABEL_A_IPV6MASK attributes,
these functions will all call netlbl_unlabel_addrinfo_get() which
will then attempt dereference NULL when fetching the non-existent
NLBL_UNLABEL_A_IPV4MASK attribute:

When extracting frames from the Ocelot switch, the frame check sequence
(FCS) is present at the end of the data extracted. The FCS was put into
the sk buffer which introduced some issues (as length related ones), as
the FCS shouldn't be part of an Rx sk buffer.
This patch fixes the Ocelot switch extraction behaviour by discarding
the FCS.

It was reported that chip version 33 (RTL8168E) ends up with
10MBit/Half on a 1GBit link after resuming from S3 (with different
link partners). For whatever reason the PHY on this chip doesn't
properly start a renegotiation when soft-reset.
Explicitly requesting a renegotiation fixes this.

When processing pmtu update from an icmp packet, it calls .update_pmtu
with sk instead of skb in sctp_transport_update_pmtu.
However for sctp, the daddr in the transport might be different from
inet_sock->inet_daddr or sk->sk_v6_daddr, which is used to update or
create the route cache. The incorrect daddr will cause a different
route cache created for the path.
So before calling .update_pmtu, inet_sock->inet_daddr/sk->sk_v6_daddr
should be updated with the daddr in the transport, and update it back
after it's done.
The issue has existed since route exceptions introduction.

MC-aware mode was introduced to mlxsw in commit 7b8195306694 ("mlxsw: spectrum:
Configure MC-aware mode on mlxsw ports") and fixed up later in commit
3a3539cd3632 ("mlxsw: spectrum_buffers: Set up a dedicated pool for BUM
traffic"). As the final piece of puzzle, a firmware issue whereby a wrong
priority was assigned to BUM traffic was corrected in FW version 13.1703.4.
Therefore require this FW version in the driver.

In certain multi-function switch dependent modes, firmware adds vlan tag 0
to the untagged frames. This leads to double tagging for the traffic
if the dcbx is enabled, which is not the desired behavior. To avoid this,

In multi-function mode, driver receives the stag value (outer vlan)
for a PF from management FW (MFW). If the stag value is negotiated prior to
the driver load, then the stag is not notified to the driver and hence
driver will have the invalid stag value.
The fix is to request the MFW for STAG value during the driver load time.

here are some bugfixes which we would like to see integrated into net.
We forgot to bump the version number in the last round for net-next, so
the belated patch to do that is included - we hope you can adopt it.
This will most likely create a merge conflict later when merging into
net-next with this rounds net-next patchset, but net-next should keep

When dst->_metrics and f6i->fib6_metrics share the same memory, both
take reference count on the dst_metrics structure. However, when dst is
destroyed, ip6_dst_destroy() only invokes dst_destroy_metrics_generic()
which does not take care of READONLY metrics and does not release refcnt.
This causes memory leak.
Similar to ipv4 logic, the fix is to properly release refcnt and free
the memory space pointed by dst->_metrics if refcnt becomes 0.

In state SMC_INIT smc_poll() delegates polling to the internal
CLC socket. This means, once the connect worker has finished
its kernel_connect() step, the poll wake-up may occur. This is not
intended. The wake-up should occur from the wake up call in
smc_connect_work() after __smc_connect() has finished.
Thus in state SMC_INIT this patch now calls sock_poll_wait() on the
main SMC socket.

EtherAVB hardware requires 0 to be written to status register bits in
order to clear them, however, care must be taken not to:
1. Clear other bits, by writing zero to them
2. Write one to reserved bits
This patch corrects the ravb driver with respect to the second point above.
This is done by defining reserved bit masks for the affected registers and,
after auditing the code, ensure all sites that may write a one to a
reserved bit use are suitably masked.

On the Netgear WNDAP620, the emac ethernet isn't receiving nor
xmitting any frames from/to the RTL8363SB (identifies itself
as a RTL8367RB).
This is caused by the emac hardware not knowing the forced link
parameters for speed, duplex, pause, etc.
This begs the question, how this was working on the original
driver code, when it was necessary to set the phy_address and
phy_map to 0xffffffff. But I guess without access to the old
PPC405/440/460 hardware, it's not possible to know.

According to ETSI TS 102 622 specification chapter 4.4 pipe identifier
is 7 bits long which allows for 128 unique pipe IDs. Because
NFC_HCI_MAX_PIPES is used as the number of pipes supported and not
as the max pipe ID, its value should be 128 instead of 127.
nfc_hci_recv_from_llc extracts pipe ID from packet header using
NFC_HCI_FRAGMENT(0x7F) mask which allows for pipe ID value of 127.
Same happens when NCI_HCP_MSG_GET_PIPE() is being used. With
pipes array having only 127 elements and pipe ID of 127 the OOB memory
access will result.

When handling SHDLC I-Frame commands "pipe" field used for indexing
into an array should be checked before usage. If left unchecked it
might access memory outside of the array of size NFC_HCI_MAX_PIPES(127).
Malformed NFC HCI frames could be injected by a malicious NFC device
communicating with the device being attacked (remote attack vector),
or even by an attacker with physical access to the I2C bus such that
they could influence the data transfers on that bus (local attack vector).
skb->data is controlled by the attacker and has only been sanitized in
the most trivial ways (CRC check), therefore we can consider the
create_info struct and all of its members to tainted. 'create_info->pipe'
with max value of 255 (uint8) is used to take an offset of the
hdev->pipes array of 127 elements which can lead to OOB write.

Currently we are always setting the tail address of descriptor list to
the end of the pre-allocated list.
According to databook this is not correct. Tail address should point to
the last available descriptor + 1, which means we have to update the
tail address everytime we call the xmit function.
This should make no impact in older versions of MAC but in newer
versions there are some DMA features which allows the IP to fetch
descriptors in advance and in a non sequential order so its critical
that we set the tail address correctly.

DST_NOCOUNT in dst_entry::flags tracks whether the entry counts
toward route cache size (net->ipv6.sysctl.ip6_rt_max_size).
If the flag is NOT set, dst_ops::pcpuc_entries counter is incremented
in dist_init() and decremented in dst_destroy().
This flag is tied to allocation/deallocation of dst_entry and
should not be copied from another dst/route. Otherwise it can happen
that dst_ops::pcpuc_entries counter grows until no new routes can
be allocated because the counter reached ip6_rt_max_size due to
DST_NOCOUNT not set and thus no counter decrements on gc-ed routes.

Recent firmware revisions have added the ability to force
these modems to USB2 mode, hiding their SuperSpeed
capabilities from the host. The driver has been using the
SuperSpeed capability, as shown by the bcdUSB field of the
device descriptor, to detect the need to enable the DTR
quirk. This method fails when the modems are forced to
USB2 mode by the modem firmware.
Fix by unconditionally enabling the DTR quirk for the
affected device IDs.

r8169 (x86) clk fixes to fix S0ix not being reached
This series adds code to the r8169 ethernet driver to get and enable an
external clock if present, avoiding the need for a hack in the
clk-pmc-atom driver where that clock was left on continuesly causing x86
some devices to not reach deep power saving states (S0ix) when suspended
causing to them to quickly drain their battery while suspended.
The 3 commits in this series need to be merged in order to avoid
regressions while bisecting. The clk-pmc-atom driver does not see much
changes (it was last touched over a year ago). So the clk maintainers
have agreed with merging all 3 patches through the net tree.
All 3 patches have Stephen Boyd's Acked-by for this purpose.

Commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the
firmware"), which added the code to mark clocks as CLK_IS_CRITICAL, causes
all unclaimed PMC clocks on Cherry Trail devices to be on all the time,
resulting on the device not being able to reach S0i3 when suspended.
The reason for this commit is that on some Bay Trail / Cherry Trail devices
the r8169 ethernet controller uses pmc_plt_clk_4. Now that the clk-pmc-atom
driver exports an "ether_clk" alias for pmc_plt_clk_4 and the r8169 driver
has been modified to get and enable this clock (if present) the marking of
the clocks as CLK_IS_CRITICAL is no longer necessary.
This commit removes the CLK_IS_CRITICAL marking, fixing Cherry Trail
devices not being able to reach S0i3 greatly decreasing their battery
drain when suspended.

On some boards a platform clock is used as clock for the r8169 chip,
this commit adds support for getting and enabling this clock (assuming

x86 boards, but this causes all Cherry Trail SoC using boards to not reach
there lowest power states when suspending.
This commit (together with an atom-pmc-clk driver commit adding the alias)
fixes things properly by making the r8169 get the clock and enable it when
it needs it.

Commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the
firmware") causes all unclaimed PMC clocks on Cherry Trail devices to be on
all the time, resulting on the device not being able to reach S0i2 or S0i3
when suspended.
The reason for this commit is that on some Bay Trail / Cherry Trail devices
the ethernet controller uses pmc_plt_clk_4. This commit adds an "ether_clk"
alias, so that the relevant ethernet drivers can try to (optionally) use
this, without needing X86 specific code / hacks, thus fixing ethernet on
these devices without breaking S0i3 support.
This commit uses clkdev_hw_create() to create the alias, mirroring the code
for the already existing "mclk" alias for pmc_plt_clk_3.

The Intel SoC was prevented from entering lower idle state because
of RTL8106E's ASPM was not enabled.
So enable ASPM on RTL8106E (chip version 39).
Now the Intel SoC can enter lower idle state, power consumption and
temperature are much lower.

There's a small delay after setting ASPM in vendor drivers, r8101 and
r8168.
In addition, those drivers enable ASPM before ClkReq, also change that
to align with vendor driver.
I haven't seen anything bad becasue of this, but I think it's better to
keep in sync with vendor driver.

The current code assumes kcm users know they need to look for the
strparser offset within their bpf program, which is not documented
anywhere and examples laying around do not do.
The actual recv function does handle the offset well, so we can create a
temporary clone of the skb and pull that one up as required for parsing.
The pull itself has a cost if we are pulling beyond the head data,
measured to 2-3% latency in a noisy VM with a local client stressing
that path. The clone's impact seemed too small to measure.
This bug can be exhibited easily by implementing a "trivial" kcm parser
taking the first bytes as size, and on the client sending at least two
such packets in a single write().
Note that bpf sockmap has the same problem, both for parse and for recv,
so it would pulling twice or a real pull within the strparser logic if
anyone cares about that.

Read TLS caps from the core driver only when TLS is supported, i.e
mlx5_accel_is_tls_device returns true.
