Igor Druzhinin b17075d5c1 xen-netback: fix race condition on XenBus disconnect
In some cases during XenBus disconnect event handling and subsequent
queue resource release there may be some TX handlers active on
other processors. Use RCU in order to synchronize with them.

David Ahern e37791ec1a mpls: Send route delete notifications when router module is unloaded
When the mpls_router module is unloaded, mpls routes are deleted but
notifications are not sent to userspace leaving userspace caches
out of sync. Add the call to mpls_notify_route in mpls_net_exit as
routes are freed.

Neil Jerram 88a7cddce2 Make IP 'forwarding' doc more precise
It wasn't clear if the 'forwarding' setting needs to be enabled on the
interface that packets are received from, or on the interface that
packets are forwarded to, or both.

In fact (according to my code reading) the setting is relevant on the
interface that packets are received from, so this change updates the doc
to say that.

Daniel Borkmann 2c4ea6e28d x86/tlb: Fix tlb flushing when lguest clears PGE
Fengguang reported random corruptions from various locations on x86-32
after commits d2852a2240 ("arch: add ARCH_HAS_SET_MEMORY config") and
9d876e79df ("bpf: fix unlocking of jited image when module ronx not set")
that uses the former. While x86-32 doesn't have a JIT like x86_64, the
bpf_prog_lock_ro() and bpf_prog_unlock_ro() got enabled due to
ARCH_HAS_SET_MEMORY, whereas Fengguang's test kernel doesn't have module
support built in and therefore never had the DEBUG_SET_MODULE_RONX setting
enabled.

After investigating the crashes further, it turned out that using
set_memory_ro() and set_memory_rw() didn't have the desired effect, for
example, setting the pages as read-only on x86-32 would still let
probe_kernel_write() succeed without error. This behavior would manifest
itself in situations where the vmalloc'ed buffer was accessed prior to
set_memory_*() such as in case of bpf_prog_alloc(). In cases where it
wasn't, the page attribute changes seemed to have taken effect, leading to
the conclusion that a TLB invalidate didn't happen. Moreover, it turned out
that this issue reproduced with qemu in "-cpu kvm64" mode, but not for
"-cpu host". When the issue occurs, change_page_attr_set_clr() did trigger
a TLB flush as expected via __flush_tlb_all() through cpa_flush_range(),
though.

There are 3 variants for issuing a TLB flush: invpcid_flush_all() (depends
on CPU feature bits X86_FEATURE_INVPCID, X86_FEATURE_PGE), cr4 based flush
(depends on X86_FEATURE_PGE), and cr3 based flush.  For "-cpu host" case in
my setup, the flush used invpcid_flush_all() variant, whereas for "-cpu
kvm64", the flush was cr4 based. Switching the kvm64 case to cr3 manually
worked fine, and further investigating the cr4 one turned out that
X86_CR4_PGE bit was not set in cr4 register, meaning the
__native_flush_tlb_global_irq_disabled() wrote cr4 twice with the same
value instead of clearing X86_CR4_PGE in the first write to trigger the
flush.

It turned out that X86_CR4_PGE was cleared from cr4 during init from
lguest_arch_host_init() via adjust_pge(). The X86_FEATURE_PGE bit is also
cleared from there due to concerns of using PGE in guest kernel that can
lead to hard to trace bugs (see bff672e630 ("lguest: documentation V:
Host") in init()). The CPU feature bits are cleared in dynamic
boot_cpu_data, but they never propagated to __flush_tlb_all() as it uses
static_cpu_has() instead of boot_cpu_has() for testing which variant of TLB
flushing to use, meaning they still used the old setting of the host
kernel.

Clearing via setup_clear_cpu_cap(X86_FEATURE_PGE) so this would propagate
to static_cpu_has() checks is too late at this point as sections have been
patched already, so for now, it seems reasonable to switch back to
boot_cpu_has(X86_FEATURE_PGE) as it was prior to commit c109bf9599
("x86/cpufeature: Remove cpu_has_pge"). This lets the TLB flush trigger via
cr3 as originally intended, properly makes the new page attributes visible
and thus fixes the crashes seen by Fengguang.

NeilBrown f5fe1b5190 blk: Ensure users for current->bio_list can see the full list.
Commit 79bd99596b ("blk: improve order of bio handling in generic_make_request()")
changed current->bio_list so that it did not contain *all* of the
queued bios, but only those submitted by the currently running
make_request_fn.

There are two places which walk the list and requeue selected bios,
and others that check if the list is empty.  These are no longer
correct.

So redefine current->bio_list to point to an array of two lists, which
contain all queued bios, and adjust various code to test or walk both
lists.

Thomas Gleixner 40c50c1fec kexec, x86/purgatory: Unbreak it and clean it up
The purgatory code defines global variables which are referenced via a
symbol lookup in the kexec code (core and arch).

A recent commit addressing sparse warnings made these static and thereby
broke kexec_file.

Why did this happen? Simply because the whole machinery is undocumented and
lacks any form of forward declarations. The variable names are unspecific
and lack a prefix, so adding forward declarations creates shadow variables
in the core code. Aside of that the code relies on magic constants and
duplicate struct definitions with no way to ensure that these things stay
in sync. The section placement of the purgatory variables happened by
chance and not by design.

Unbreak kexec and cleanup the mess:

 - Add proper forward declarations and document the usage
 - Use common struct definition
 - Use the proper common defines instead of magic constants
 - Add a purgatory_ prefix to have a proper name space
 - Use ARRAY_SIZE() instead of a homebrewn reimplementation
 - Add proper sections to the purgatory variables [ From Mike ]

Change packet type handler to ETH_P_IP instead of ETH_P_ALL
since we are already expecting an IP packet.

Also, using ETH_P_ALL will cause the loopback test packet type handler
to be called on all outgoing packets, especially our own self loopback
test SKB, which will be validated on xmit as well, and we don't want that.

ethtool -t ethX

Or Gerlitz 65ba8fb7d5 net/mlx5e: Avoid wrong identification of rules on deletion
When deleting offloaded TC flows, we must correctly identify E-switch
rules. The current check could get us wrong w.r.t to rules set on the
PF. Since it's possible to set NIC rules on the PF, switch to SRIOV
offloads mode and then attempt to delete a NIC rule.

To solve that, we add a flags field to offloaded rules, set it on
creation time and use that over the code where currently needed.

The autogroups list is a list of non overlapping group boundaries
sorted by their start index. If the autogroups list wasn't empty
and an empty group slot was found at the start of the list,
the new group was added to the end of the list instead of the
beginning, as the prev initializer was incorrect.
When this was repeated, it caused multiple groups to have
overlapping boundaries.

Fixed that by correctly initializing the prev pointer to the
start of the list.

David Howells 702f2ac87a rxrpc: Wake up the transmitter if Rx window size increases on the peer
The RxRPC ACK packet may contain an extension that includes the peer's
current Rx window size for this call.  We adjust the local Tx window size
to match.  However, the transmitter can stall if the receive window is
reduced to 0 by the peer and then reopened.

This is because the normal way that the transmitter is re-energised is by
dropping something out of our Tx queue and thus making space.  When a
single gap is made, the transmitter is woken up.  However, because there's
nothing in the Tx queue at this point, this doesn't happen.

To fix this, perform a wake_up() any time we see the peer's Rx window size
increasing.

The observable symptom is that calls start failing on ETIMEDOUT and the
following:

	kAFS: SERVER DEAD state=-62

appears in dmesg.

Matjaz Hegedic bba8376aea x86/reboot/quirks: Fix typo in ASUS EeeBook X205TA reboot quirk
The reboot quirk for ASUS EeeBook X205TA contains a typo in
DMI_PRODUCT_NAME, improperly referring to X205TAW instead of
X205TA, which prevents the quirk from being triggered. The
model X205TAW already has a reboot quirk of its own.

This fix simply removes the inappropriate final letter W.

Andrew Lunn 296739839f net: phy: marvell: Fix double free of hwmon device
The hwmon temperature sensor devices is registered using a devm_hwmon
API call.  The marvell_release() would then manually free the device,
not using a devm_hmon API, resulting in the device being removed
twice, leading to a crash in kernfs_find_ns() during the second
removal.

Remove the manual removal, which makes marvell_release() empty, so
remove it as well.

Nicholas Piggin 7b9f71f974 powerpc/64s: POWER9 machine check handler
Add POWER9 machine check handler. There are several new types of errors
added, so logging messages for those are also added.

This doesn't attempt to reuse any of the P7/8 defines or functions,
because that becomes too complex. The better option in future is to use
a table driven approach.

Nicholas Piggin 1363875bdb powerpc/64s: fix handling of non-synchronous machine checks
A synchronous machine check is an exception raised by the attempt to
execute the current instruction. If the error can't be corrected, it
can make sense to SIGBUS the currently running process.

In other cases, the error condition is not related to the current
instruction, so killing the current process is not the right thing to
do.

Today, all machine checks are MCE_SEV_ERROR_SYNC, so this has no
practical change. It will be used to handle POWER9 asynchronous
machine checks.

Commit 5657933dbb ("treewide: Move dma_ops from struct dev_archdata

backtrace being:

This was caused by the device having NULL dma_ops, triggering the
BUG_ON(). Previously the device inherited its dma_ops via the assignment
to dev->ofdev.dev.archdata. However after commit 5657933dbb the
dma_ops are moved into dev->ofdev.dev, and so they need to be explicitly
copied.

Doug Berger says:

====================
net: bcmgenet: minor bug fixes

v2: Accidentally sent the wrong set after rebasing.

This collection contains a number of fixes for minor issues with the
bcmgenet driver most of which were present in the initial submission
of the driver.

Some bugs were uncovered by inspection prior to the upcoming update for
GENETv5 support:
  net: bcmgenet: correct the RBUF_OVFL_CNT and RBUF_ERR_CNT MIB values
  net: bcmgenet: correct MIB access of UniMAC RUNT counters
  net: bcmgenet: reserved phy revisions must be checked first
  net: bcmgenet: synchronize irq0 status between the isr and task

Others bugs were found in power management testing:
  net: bcmgenet: power down internal phy if open or resume fails
  net: bcmgenet: Power up the internal PHY before probing the MII
  net: bcmgenet: decouple flow control from bcmgenet_tx_reclaim
  net: bcmgenet: add begin/complete ethtool ops

Doug Berger 6d22fe1400 net: bcmgenet: decouple flow control from bcmgenet_tx_reclaim
The bcmgenet_tx_reclaim() function is used to reclaim transmit
resources in different places within the driver.  Most of them
should not affect the state of the transmit flow control.

This commit relocates the logic for waking tx queues based on
freed resources to the napi polling function where it is more
appropriate.

Doug Berger 6be371b053 net: bcmgenet: Power up the internal PHY before probing the MII
When using the internal PHY it must be powered up when the MII is probed
or the PHY will not be detected.  Since the PHY is powered up at reset
this has not been a problem.  However, when the kernel is restarted with
kexec the PHY will likely be powered down when the kernel starts so it
will not be detected and the Ethernet link will not be established.

This commit explicitly powers up the internal PHY when the GENET driver
is probed to correct this behavior.
