The timestamping API has separate bits for generating and reporting
timestamps. A software timestamp should only be reported for a packet
when the packet has the relevant generation flag (SKBTX_..) set
and the socket has reporting bit SOF_TIMESTAMPING_SOFTWARE set.
The second check was accidentally removed. Reinstitute the original
behavior.
Tested:
Without this patch, Documentation/networking/txtimestamp reports
timestamps regardless of whether SOF_TIMESTAMPING_SOFTWARE is set.
After the patch, it only reports them when the flag is set.

pull request: Netfilter/IPVS fixes for net
The following patchset contains seven Netfilter fixes for your net
tree, they are:
1) Make the NAT infrastructure independent of x_tables, some users are
already starting to test nf_tables with NAT without enabling x_tables.
Without this patch for Kconfig, there's a superfluous dependency
between NAT and x_tables.
2) Allow to use 0 in the cgroup match, the kernel rejects with -EINVAL
with no good reason. From Daniel Borkmann.
3) Select CONFIG_NF_NAT from the nf_tables NAT expression, this also
resolves another NAT dependency with x_tables.
4) Use HAVE_JUMP_LABEL instead of CONFIG_JUMP_LABEL in the Netfilter hook
code as elsewhere in the kernel to resolve toolchain problems, from
Zhouyi Zhou.
5) Use iptunnel_handle_offloads() to set up tunnel encapsulation
depending on the offload capabilities, reported by Alex Gartrell
patch from Julian Anastasov.
6) Fix wrong family when registering the ip_vs_local_reply6() hook,
also from Julian.
7) Select the NF_LOG_* symbols from NETFILTER_XT_TARGET_LOG. Rafał
Miłecki reported that when jumping from 3.16 to 3.17-rc, his log
target is not selected anymore due to changes in the previous
development cycle to accomodate the full logging support for

Some hosts can be both little and big endian.
In certain scenarios a big endian kernel can kexec a little endian kernel.
This patch fixes this case from both ends:
1) Return endianity to original values on shutdown (in case little endian kernel boots after we shutdown).
2) Do not rely on HW reset values when loading driver in little endian kernel
but configure them explicitly (in case previous kernel was big endian and did not reset the HW).

When qeth device is queried for ethtool data, hardware operation
is performed to extract the necessary information from the card.
If the card is not online at the moment (e.g. it is undergoing
recovery), this operation produces undesired effects like
temporarily freezing the system. This patch prevents execution
of the hardware query operation when the card is not online.
In such case, ioctl() operation returns error with errno ENODEV.

Second, if ifdown (tg3_close) is called between tg3_io_error_detected()

a tg3_napi_enable between. Once during tg3_io_error_detected() and again
during tg3_close(). The tg3_io_resume() then hangs on rtnl_lock().

Since SCTP day 1, that is, 19b55a2af145 ("Initial commit") from lksctp
tree, the official <netinet/sctp.h> header carries a copy of enum
sctp_sstat_state that looks like (compared to the current in-kernel
enumeration):
User definition: Kernel definition:
enum sctp_sstat_state { typedef enum {
SCTP_EMPTY = 0, <removed>
SCTP_CLOSED = 1, SCTP_STATE_CLOSED = 0,
SCTP_COOKIE_WAIT = 2, SCTP_STATE_COOKIE_WAIT = 1,
SCTP_COOKIE_ECHOED = 3, SCTP_STATE_COOKIE_ECHOED = 2,
SCTP_ESTABLISHED = 4, SCTP_STATE_ESTABLISHED = 3,
SCTP_SHUTDOWN_PENDING = 5, SCTP_STATE_SHUTDOWN_PENDING = 4,
SCTP_SHUTDOWN_SENT = 6, SCTP_STATE_SHUTDOWN_SENT = 5,
SCTP_SHUTDOWN_RECEIVED = 7, SCTP_STATE_SHUTDOWN_RECEIVED = 6,
SCTP_SHUTDOWN_ACK_SENT = 8, SCTP_STATE_SHUTDOWN_ACK_SENT = 7,
}; } sctp_state_t;
This header was later on also placed into the uapi, so that user space
programs can compile without having <netinet/sctp.h>, but the shipped
with <linux/sctp.h> instead.
While RFC6458 under 8.2.1.Association Status (SCTP_STATUS) says that
sstat_state can range from SCTP_CLOSED to SCTP_SHUTDOWN_ACK_SENT, we
nevertheless have a what it appears to be dummy SCTP_EMPTY state from
the very early days.
While it seems to do just nothing, commit 0b8f9e25b0 ("sctp: remove
completely unsed EMPTY state") did the right thing and removed this dead
code. That however, causes an off-by-one when the user asks the SCTP
stack via SCTP_STATUS API and checks for the current socket state thus
yielding possibly undefined behaviour in applications as they expect
the kernel to tell the right thing.
The enumeration had to be changed however as based on the current socket
state, we access a function pointer lookup-table through this. Therefore,
I think the best way to deal with this is just to add a helper function
sctp_assoc_to_state() to encapsulate the off-by-one quirk.

In commit ed98df3361 ("net: use __GFP_NORETRY for high order
allocations") we tried to address one issue caused by order-3
allocations.
We still observe high latencies and system overhead in situations where
compaction is not successful.
Instead of trying order-3, order-2, and order-1, do a single order-3
best effort and immediately fallback to plain order-0.
This mimics slub strategy to fallback to slab min order if the high
order allocation used for performance failed.
Order-3 allocations give a performance boost only if they can be done
without recurring and expensive memory scan.
Quoting David :
The page allocator relies on synchronous (sync light) memory compaction
after direct reclaim for allocations that don't retry and deferred
compaction doesn't work with this strategy because the allocation order
is always decreasing from the previous failed attempt.
This means sync light compaction will always be encountered if memory
cannot be defragmented or reclaimed several times during the
skb_page_frag_refill() iteration.

Register, was erroneously hard-coded (as reported in the databook just as

The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a

If not passed, the main driver clock will be used as default; note that
this can be fine on some platforms.

as side effect, the ptp clock can move faster/slower than the system clock.
