Madalin reported crashes happening in tcp_tasklet_func() on powerpc64
Before TSQ_QUEUED bit is cleared, we must ensure the changes done
by list_del(&tp->tsq_node); are committed to memory, otherwise
corruption might happen, as an other cpu could catch TSQ_QUEUED
clearance too soon.
We can notice that old kernels were immune to this bug, because
TSQ_QUEUED was cleared after a bh_lock_sock(sk)/bh_unlock_sock(sk)
section, but they could have missed a kick to write additional bytes,
when NIC interrupts for a given flow are spread to multiple cpus.
Affected TCP flows would need an incoming ACK or RTO timer to add more
packets to the pipe. So overall situation should be better now.

Commit 8924feff66f3 ("splice: lift pipe_lock out of splice_to_pipe()")
caused a regression when there were no more readers left on a pipe that
was being spliced into: rather than the expected SIGPIPE and -EPIPE
return value, the writer would end up waiting forever for space to free
up (which obviously was not going to happen with no readers around).

Since commit 71ce391dfb784 ("net: mvpp2: enable proper per-CPU TX
buffers unmapping"), we are not correctly DMA unmapping TX buffers for
fragments.
Indeed, the mvpp2_txq_inc_put() function only stores in the
txq_cpu->tx_buffs[] array the physical address of the buffer to be
DMA-unmapped when skb != NULL. In addition, when DMA-unmapping, we use
skb_headlen(skb) to get the size to be unmapped. Both of this works fine
for TX descriptors that are associated directly to a SKB, but not the
ones that are used for fragments, with a NULL pointer as skb:
- We have a NULL physical address when calling DMA unmap
- skb_headlen(skb) crashes because skb is NULL
This causes random crashes when fragments are used.
To solve this problem, we need to:
- Store the physical address of the buffer to be unmapped
unconditionally, regardless of whether it is tied to a SKB or not.
- Store the length of the buffer to be unmapped, which requires a new
field.
Instead of adding a third array to store the length of the buffer to be
unmapped, and as suggested by David Miller, this commit refactors the
tx_buffs[] and tx_skb[] arrays of 'struct mvpp2_txq_pcpu' into a
separate structure 'mvpp2_txq_pcpu_buf', to which a 'size' field is
added. Therefore, instead of having three arrays to allocate/free, we
have a single one, which also improve data locality, reducing the
impact on the CPU cache.

Right now the dwmac-rk tries to set up the GRF-specific speed and link
options before enabling clocks, phys etc and on previous socs this works
because the GRF is supplied on the whole by one clock.
On the rk3399 however the GRF (General Register Files) clock-supply
has been split into multiple clocks and while there is no specific
grf-gmac clock like for other sub-blocks, it seems the mac-specific
portions are actually supplied by the general mac clock.
This results in hangs on rk3399 boards if the driver is build as module.
When built in te problem of course doesn't surface, as the clocks
are of course still on at the stage before clock_disable_unused.
To solve this, simply move the clock enablement to the first position
in the powerup callback. This is also a good idea in general to
enable clocks before everything else.
Tested on rk3288, rk3368 and rk3399 the dwmac still works on all of them.

This reverts commit 16200948d8353fe29a473a394d7d26790deae0e7.
The commit was intended to cover the race condition, but it introduced
yet another regression for devices with the implicit feedback, leading
to a kernel panic due to NULL-dereference in an irq context.
As the race condition that was addressed by the commit is very rare
and the regression is much worse, let's revert the commit for rc1, and
fix the issue properly in a later patch.

Commit 3322d0d64f4e ("selinux: keep SELinux in sync with new capability
definitions") added a check on the defined capabilities without
explicitly including the capability header file which caused problems
when building genheaders for users of clang/llvm. Resolve this by
using the kernel headers when building genheaders, which is arguably
the right thing to do regardless, and explicitly including the
kernel's capability.h header file in classmap.h. We also update the
mdp build, even though it wasn't causing an error we really should
be using the headers from the kernel we are building.

kfree_skb() was inside a spinlock. What was forgotten is that kfree_skb()
guards against a NULL value for the argument. Routine dev_kfree_skb_irq()
does not, and a test is needed to prevent kernel panics.

which has been passed to us through boot params. (That still gets used

The mmc_read_ssr() function results in DMA to the raw_ssr member of
struct mmc_card, which is not guaranteed to be cache line aligned & thus
might not meet the requirements set out in Documentation/DMA-API.txt:
Warnings: Memory coherency operates at a granularity called the cache
line width. In order for memory mapped by this API to operate
correctly, the mapped region must begin exactly on a cache line
boundary and end exactly on one (to prevent two separately mapped
regions from sharing a single cache line). Since the cache line size
may not be known at compile time, the API will not enforce this
requirement. Therefore, it is recommended that driver writers who
don't take special care to determine the cache line size at run time
only map virtual regions that begin and end on page boundaries (which
are guaranteed also to be cache line boundaries).
On some systems where DMA is non-coherent this can lead to us losing
data that shares cache lines with the raw_ssr array.
Fix this by kmalloc'ing a temporary buffer to perform DMA into. kmalloc
will ensure the buffer is suitably aligned, allowing the DMA to be
performed without any loss of data.

Since CPU hotplug callbacks are requested for CPUHP_AP_ONLINE_DYN state,
successful callback initialization will result in cpuhp_setup_state()
returning a positive value. Therefore acpi_cpufreq_online being zero
indicates that callbacks have not been installed.
This means that acpi_cpufreq_boost_exit() should only remove them if
acpi_cpufreq_online is positive. Trying to call
cpuhp_remove_state_nocalls(0) will cause a BUG().

This patch removes the users of the deprectated APIs:
acpi_get_table_with_size()
early_acpi_os_unmap_memory()
The following APIs should be used instead of:
acpi_get_table()
acpi_put_table()
The deprecated APIs are invented to be a replacement of acpi_get_table()
during the early stage so that the early mapped pointer will not be stored
in ACPICA core and thus the late stage acpi_get_table() won't return a
wrong pointer. The mapping size is returned just because it is required by
early_acpi_os_unmap_memory() to unmap the pointer during early stage.
But as the mapping size equals to the acpi_table_header.length
(see acpi_tb_init_table_descriptor() and acpi_tb_validate_table()), when
such a convenient result is returned, driver code will start to use it
instead of accessing acpi_table_header to obtain the length.
Thus this patch cleans up the drivers by replacing returned table size with
acpi_table_header.length, and should be a no-op.

ACPICA commit cac6790954d4d752a083e6122220b8a22febcd07
This patch back ports Linux acpi_get_table_with_size() and
early_acpi_os_unmap_memory() into ACPICA upstream to reduce divergences.
The 2 APIs are used by Linux as table management APIs for long time, it
contains a hidden logic that during the early stage, the mapped tables
should be unmapped before the early stage ends.
During the early stage, tables are handled by the following sequence:
acpi_get_table_with_size();
parse the table
early_acpi_os_unmap_memory();
During the late stage, tables are handled by the following sequence:
acpi_get_table();
parse the table
Linux uses acpi_gbl_permanent_mmap to distinguish the early stage and the
late stage.
The reasoning of introducing acpi_get_table_with_size() is: ACPICA will
remember the early mapped pointer in acpi_get_table() and Linux isn't able to
prevent ACPICA from using the wrong early mapped pointer during the late
stage as there is no API provided from ACPICA to be an inverse of
acpi_get_table() to forget the early mapped pointer.
But how ACPICA can work with the early/late stage requirement? Inside of
ACPICA, tables are ensured to be remained in "INSTALLED" state during the
early stage, and they are carefully not transitioned to "VALIDATED" state
until the late stage. So the same logic is in fact implemented inside of
ACPICA in a different way. The gap is only that the feature is not provided
to the OSPMs in an accessible external API style.
It then is possible to fix the gap by providing an inverse of
acpi_get_table() from ACPICA, so that the two Linux sequences can be
combined:
acpi_get_table();
parse the table
acpi_put_table();
In order to work easier with the current Linux code, acpi_get_table() and
acpi_put_table() is implemented in a usage counting based style:
1. When the usage count of the table is increased from 0 to 1, table is
mapped and .Pointer is set with the mapping address (VALIDATED);
2. When the usage count of the table is decreased from 1 to 0, .Pointer
is unset and the mapping address is unmapped (INVALIDATED).
So that we can deploy the new APIs to Linux with minimal effort by just
invoking acpi_get_table() in acpi_get_table_with_size() and invoking
acpi_put_table() in early_acpi_os_unmap_memory(). Lv Zheng.

sctp.local_addr_list is a global address list that is supposed to include
all the local addresses. sctp updates this list according to NETDEV_UP/
NETDEV_DOWN notifications.
However, if multiple NICs have the same address, the global list would
have duplicate addresses. Even if for one NIC, promote secondaries in
__inet_del_ifa can also lead to accumulating duplicate addresses.
When sctp binds address 'ANY' and creates a connection, it copies all
the addresses from global list into asoc's bind addr list, which makes
sctp pack the duplicate addresses into INIT/INIT_ACK packets.
This patch is to filter the duplicate addresses when copying the addrs
from global list in sctp_copy_local_addr_list and unpacking addr_param
from cookie in sctp_raw_to_bind_addrs to asoc's bind addr list.
Note that we can't filter the duplicate addrs when global address list
gets updated, As NETDEV_DOWN event may remove an addr that still exists
in another NIC.

Add a break statement to prevent fall-through from
OVS_KEY_ATTR_ETHERNET to OVS_KEY_ATTR_TUNNEL. Without the break
actions setting ethernet addresses fail to validate with log messages
complaining about invalid tunnel attributes.

In ethtool ops, it needs to retrieve the corresponding
ethss module (gbe or xgbe) from the net_device structure.
Prior to this patch, the retrieving procedure only
checks for the gbe module. This patch fixes the issue
by checking the xgbe module if the net_device structure
does not correspond to the gbe module.

The patches regarding eee-broken-modes was merged before all people
involved could find an agreement on the best way to move forward.
While we agreed on having a DT property to mark particular modes as broken,
the value used for eee-broken-modes mapped the phy register in very direct
way. Because of this, the concern is that it could be used to implement
configuration policies instead of describing a broken HW.
In the end, having a boolean property for each mode seems to be preferred
over one bit field value mapping the register (too) directly.

In genphy_config_eee_advert, the return value of phy_read_mmd_indirect is
checked to know if the register could be accessed but the result is
assigned to a 'u32'.
Changing to 'int' to correctly get errors from phy_read_mmd_indirect.
