Jana Iyengar found an interesting issue on CUBIC :
The epoch is only updated/reset initially and when experiencing losses.
The delta "t" of now - epoch_start can be arbitrary large after app idle
as well as the bic_target. Consequentially the slope (inverse of
ca->cnt) would be really large, and eventually ca->cnt would be
lower-bounded in the end to 2 to have delayed-ACK slow-start behavior.
This particularly shows up when slow_start_after_idle is disabled
as a dangerous cwnd inflation (1.5 x RTT) after few seconds of idle
time.
Jana initial fix was to reset epoch_start if app limited,
but Neal pointed out it would ask the CUBIC algorithm to recalculate the
curve so that we again start growing steeply upward from where cwnd is
now (as CUBIC does just after a loss). Ideally we'd want the cwnd growth
curve to be the same shape, just shifted later in time by the amount of
the idle period.

Issuing a CC TX_START event on control frames like pure ACK
is a waste of time, as a CC should not care.
Following patch needs this change, as we want CUBIC to properly track
idle time at a low cost, with a single TX_START being generated.
Yuchung might slightly refine the condition triggering TX_START
on a followup patch.

Originally that parameter was always reset to num_online_cpus during

The fix is to only set max_queues to num_online_cpus when user has not

Just like single link MIPI panels, similarly for dual link panels, pipe

If one disables DDR DVFS in the BIOS, Punit will apparently ignores
all DDR DVFS request. Currently we assume that DDR DVFS is always
operational, which leads to errors in dmesg when the DDR DVFS requests
time out.
Fix the problem by gently prodding Punit during driver load to find out
whether it will respond to DDR DVFS requests. If the request times out,
we assume that DDR DVFS has been permanenly disabled in the BIOS and
no longer perster the Punit about it.

AUDIT_ARCH_MICROBLAZE, but it's only available in the microblaze
asm headers. Move it to the common elf-em.h header so that the
define can be used on non-microblaze systems. Otherwise we get
build errors that EM_MICROBLAZE isn't defined when we try to use
the AUDIT_ARCH_MICROBLAZE symbol.

When netlink mmap on receive side is the consumer of nf queue data,
it can happen that in some edge cases, we write skb shared info into
the user space mmap buffer:
Assume a possible rx ring frame size of only 4096, and the network skb,
which is being zero-copied into the netlink skb, contains page frags
with an overall skb->len larger than the linear part of the netlink
skb.
skb_zerocopy(), which is generic and thus not aware of the fact that
shared info cannot be accessed for such skbs then tries to write and
fill frags, thus leaking kernel data/pointers and in some corner cases
possibly writing out of bounds of the mmap area (when filling the
last slot in the ring buffer this way).
I.e. the ring buffer slot is then of status NL_MMAP_STATUS_VALID, has
an advertised length larger than 4096, where the linear part is visible
at the slot beginning, and the leaked sizeof(struct skb_shared_info)
has been written to the beginning of the next slot (also corrupting
the struct nl_mmap_hdr slot header incl. status etc), since skb->end
points to skb->data + ring->frame_size - NL_MMAP_HDRLEN.
The fix adds and lets __netlink_alloc_skb() take the actual needed
linear room for the network skb + meta data into account. It's completely
irrelevant for non-mmaped netlink sockets, but in case mmap sockets
are used, it can be decided whether the available skb_tailroom() is
really large enough for the buffer, or whether it needs to internally
fallback to a normal alloc_skb().
>From nf queue side, the information whether the destination port is
an mmap RX ring is not really available without extra port-to-socket
lookup, thus it can only be determined in lower layers i.e. when
__netlink_alloc_skb() is called that checks internally for this. I
chose to add the extra ldiff parameter as mmap will then still work:
We have data_len and hlen in nfqnl_build_packet_message(), data_len
is the full length (capped at queue->copy_range) for skb_zerocopy()
and hlen some possible part of data_len that needs to be copied; the
rem_len variable indicates the needed remaining linear mmap space.
The only other workaround in nf queue internally would be after
allocation time by f.e. cap'ing the data_len to the skb_tailroom()
iff we deal with an mmap skb, but that would 1) expose the fact that
we use a mmap skb to upper layers, and 2) trim the skb where we
otherwise could just have moved the full skb into the normal receive
queue.
After the patch, in my test case the ring slot doesn't fit and therefore
shows NL_MMAP_STATUS_COPY, where a full skb carries all the data and
thus needs to be picked up via recv().

In case of netlink mmap, there can be situations where received frames
have to be placed into the normal receive queue. The ring buffer indicates
this through NL_MMAP_STATUS_COPY, so the user is asked to pick them up
via recvmsg(2) syscall, and to put the slot back to NL_MMAP_STATUS_UNUSED.
Commit 0ef707700f1c ("netlink: rx mmap: fix POLLIN condition") changed
polling, so that we walk in the worst case the whole ring through the
new netlink_has_valid_frame(), for example, when the ring would have no
NL_MMAP_STATUS_VALID, but at least one NL_MMAP_STATUS_COPY frame.
Since we do a datagram_poll() already earlier to pick up a mask that could
possibly contain POLLIN | POLLRDNORM already (due to NL_MMAP_STATUS_COPY),
we can skip checking the rx ring entirely.
In case the kernel is compiled with !CONFIG_NETLINK_MMAP, then all this is
irrelevant anyway as netlink_poll() is just defined as datagram_poll().

There exist one issue by below case that case system hang:
ifconfig eth0 down
ifconfig eth0 hw ether 00:10:19:19:81:19
After eth0 down, all fec clocks are gated off. In the .fec_set_mac_address()
function, it will set new MAC address to registers, which causes system hang.
So it needs to add netif status check to avoid registers access when clocks are
gated off. Until eth0 up the new MAC address are wrote into related registers.

Current check of phydev with IS_ERR(phydev) may make not much sense
because of_phy_connect() returns NULL on failure instead of error value.
Still for checking result of phy_connect() IS_ERR() makes perfect sense.
So let's use combined check IS_ERR_OR_NULL() that covers both cases.

This switches IPv6 policy routing to use the shared
fib_default_rule_pref() function of IPv4 and DECnet. It is also used in
multicast routing for IPv4 as well as IPv6.
The motivation for this patch is a complaint about iproute2 behaving
inconsistent between IPv4 and IPv6 when adding policy rules: Formerly,
IPv6 rules were assigned a fixed priority of 0x3FFF whereas for IPv4 the
assigned priority value was decreased with each rule added.
Since then all users of the default_pref field have been converted to
assign the generic function fib_default_rule_pref(), fib_nl_newrule()
may just use it directly instead. Therefore get rid of the function
pointer altogether and make fib_default_rule_pref() static, as it's not
used outside fib_rules.c anymore.

Problem:
The ecmp route replace support for ipv6 in the kernel, deletes the
existing ecmp route too early, ie when it installs the first nexthop.
If there is an error in installing the subsequent nexthops, its too late
to recover the already deleted existing route leaving the fib
in an inconsistent state.
This patch reduces the possibility of this by doing the following:
a) Changes the existing multipath route add code to a two stage process:
build rt6_infos + insert them
ip6_route_add rt6_info creation code is moved into
ip6_route_info_create.
b) This ensures that most errors are caught during building rt6_infos
and we fail early
c) Separates multipath add and del code. Because add needs the special
two stage mode in a) and delete essentially does not care.
d) In any event if the code fails during inserting a route again, a
warning is printed (This should be unlikely)
Before the patch:

return the results of the private lookup.
