bridge: only provide proxy ARP when CONFIG_INET is enabled
When IPV4 support is disabled, we cannot call arp_send from

neighbour: fix base_reachable_time(_ms) not effective immediatly when changed
When setting base_reachable_time or base_reachable_time_ms on a
specific interface through sysctl or netlink, the reachable_time
value is not updated.
This means that neighbour entries will continue to be updated using the
old value until it is recomputed in neigh_period_work (which
recomputes the value every 300*HZ).
On systems with HZ equal to 1000 for instance, it means 5mins before
the change is effective.
This patch changes this behavior by recomputing reachable_time after
each set on base_reachable_time or base_reachable_time_ms.
The new value will become effective the next time the neighbour's timer
is triggered.
Changes are made in two places: the netlink code for set and the sysctl
handling code. For sysctl, I use a proc_handler. The ipv6 network
code does provide its own handler but it already refreshes
reachable_time correctly so it's not an issue.
Any other user of neighbour which provide its own handlers must
refresh reachable_time.

net: fec: fix MDIO bus assignement for dual fec SoC's
On i.MX28, the MDIO bus is shared between the two FEC instances.
The driver makes sure that the second FEC uses the MDIO bus of the
first FEC. This is done conditionally if FEC_QUIRK_ENET_MAC is set.
However, in newer designs, such as Vybrid or i.MX6SX, each FEC MAC
has its own MDIO bus. Simply removing the quirk FEC_QUIRK_ENET_MAC
is not an option since other logic, triggered by this quirk, is
still needed.
Furthermore, there are board designs which use the same MDIO bus
for both PHY's even though the second bus would be available on the
SoC side. Such layout are popular since it saves pins on SoC side.
Due to the above quirk, those boards currently do work fine. The
boards in the mainline tree with such a layout are:
- Freescale Vybrid Tower with TWR-SER2 (vf610-twr.dts)
- Freescale i.MX6 SoloX SDB Board (imx6sx-sdb.dts)
This patch adds a new quirk FEC_QUIRK_SINGLE_MDIO for i.MX28, which
makes sure that the MDIO bus of the first FEC is used in any case.
However, the boards above do have a SoC with a MDIO bus for each FEC
instance. But the PHY's are not connected in a 1:1 configuration. A
proper device tree description is needed to allow the driver to
figure out where to find its PHY. This patch fixes that shortcoming
by adding a MDIO bus child node to the first FEC instance, along
with the two PHY's on that bus, and making use of the phy-handle
property to add a reference to the PHY's.

tipc: fix bug in broadcast retransmit code
In commit
58dc55f25631178ee74cd27185956a8f7dcb3e32 ("tipc: use generic
SKB list APIs to manage link transmission queue") we replace all list
traversal loops with the macros skb_queue_walk() or
skb_queue_walk_safe(). While the previous loops were based on the
assumption that the list was NULL-terminated, the standard macros
stop when the iterator reaches the list head, which is non-NULL.
In the function bclink_retransmit_pkt() this macro replacement has
lead to a bug. When we receive a BCAST STATE_MSG we unconditionally
call the function bclink_retransmit_pkt(), whether there really is
anything to retransmit or not, assuming that the sequence number
comparisons will lead to the correct behavior. However, if the
transmission queue is empty, or if there are no eligible buffers in
the transmission queue, we will by mistake pass the list head pointer
to the function tipc_link_retransmit(). Since the list head is not a
valid sk_buff, this leads to a crash.
In this commit we fix this by only calling tipc_link_retransmit()
if we actually found eligible buffers in the transmission queue.

netfilter: conntrack: fix race between confirmation and flush
Commit
5195c14c8b27c ("netfilter: conntrack: fix race in
__nf_conntrack_confirm against get_next_corpse") aimed to resolve the
race condition between the confirmation (packet path) and the flush
command (from control plane). However, it introduced a crash when
several packets race to add a new conntrack, which seems easier to
reproduce when nf_queue is in place.
Fix this race, in __nf_conntrack_confirm(), by removing the CT
from unconfirmed list before checking the DYING bit. In case
race occured, re-add the CT to the dying list
This patch also changes the verdict from NF_ACCEPT to NF_DROP when
we lose race. Basically, the confirmation happens for the first packet
that we see in a flow. If you just invoked conntrack -F once (which
should be the common case), then this is likely to be the first packet
of the flow (unless you already called flush anytime soon in the past).
This should be hard to trigger, but better drop this packet, otherwise
we leave things in inconsistent state since the destination will likely
reply to this packet, but it will find no conntrack, unless the origin
retransmits.

mm: propagate error from stack expansion even for guard page
Jay Foad reports that the address sanitizer test (asan) sometimes gets
confused by a stack pointer that ends up being outside the stack vma
that is reported by /proc/maps.
This happens due to an interaction between RLIMIT_STACK and the guard
page: when we do the guard page check, we ignore the potential error
from the stack expansion, which effectively results in a missing guard
page, since the expected stack expansion won't have been done.
And since /proc/maps explicitly ignores the guard page (commit
d7824370e263: "mm: fix up some user-visible effects of the stack guard
page"), the stack pointer ends up being outside the reported stack area.
This is the minimal patch: it just propagates the error. It also
effectively makes the guard page part of the stack limit, which in turn
measn that the actual real stack is one page less than the stack limit.
Let's see if anybody notices. We could teach acct_stack_growth() to
allow an extra page for a grow-up/grow-down stack in the rlimit test,
but I don't want to add more complexity if it isn't needed.

batman-adv: fix potential TT client + orig-node memory leak
This patch fixes a potential memory leak which can occur once an
originator times out. On timeout the according global translation table
entry might not get purged correctly. Furthermore, the non purged TT
entry will cause its orig-node to leak, too. Which additionally can lead
to the new multicast optimization feature not kicking in because of a
therefore bogus counter.
In detail: The batadv_tt_global_entry->orig_list holds the reference to
the orig-node. Usually this reference is released after
BATADV_PURGE_TIMEOUT through: _batadv_purge_orig()->
batadv_purge_orig_node()->batadv_update_route()->_batadv_update_route()->
batadv_tt_global_del_orig() which purges this global tt entry and
releases the reference to the orig-node.
However, if between two batadv_purge_orig_node() calls the orig-node
timeout grew to 2*BATADV_PURGE_TIMEOUT then this call path isn't
reached. Instead the according orig-node is removed from the
originator hash in _batadv_purge_orig(), the batadv_update_route()
part is skipped and won't be reached anymore.
Fixing the issue by moving batadv_tt_global_del_orig() out of the rcu
callback.

batman-adv: fix delayed foreign originator recognition
Currently it can happen that the reception of an OGM from a new
originator is not being accepted. More precisely it can happen that
an originator struct gets allocated and initialized
(batadv_orig_node_new()), even the TQ gets calculated and set correctly
(batadv_iv_ogm_calc_tq()) but still the periodic orig_node purging
thread will decide to delete it if it has a chance to jump between
these two function calls.
This is because batadv_orig_node_new() initializes the last_seen value
to zero and its caller (batadv_iv_ogm_orig_get()) makes it visible to
other threads by adding it to the hash table already.
batadv_iv_ogm_calc_tq() will set the last_seen variable to the correct,
current time a few lines later but if the purging thread jumps in between
that it will think that the orig_node timed out and will wrongly
schedule it for deletion already.
If the purging interval is the same as the originator interval (which is
the default: 1 second), then this game can continue for several rounds
until the random OGM jitter added enough difference between these
two (in tests, two to about four rounds seemed common).
Fixing this by initializing the last_seen variable of an orig_node

net: ethernet: cpsw: fix hangs with interrupts
The CPSW IP implements pulse-signaled interrupts. Due to
that we must write a correct, pre-defined value to the
CPDMA_MACEOIVECTOR register so the controller generates
a pulse on the correct IRQ line to signal the End Of
Interrupt.
The way the driver is written today, all four IRQ lines
are requested using the same IRQ handler and, because of
that, we could fall into situations where a TX IRQ fires
but we tell the controller that we ended an RX IRQ (or
vice-versa). This situation triggers an IRQ storm on the
reserved IRQ 127 of INTC which will in turn call ack_bad_irq()
which will, then, print a ton of:
unexpected IRQ trap at vector 00
In order to fix the problem, we are moving all calls to
cpdma_ctlr_eoi() inside the IRQ handler and making sure
we *always* write the correct value to the CPDMA_MACEOIVECTOR
register. Note that the algorithm assumes that IRQ numbers and
value-to-be-written-to-EOI are proportional, meaning that a
write of value 0 would trigger an EOI pulse for the RX_THRESHOLD
Interrupt and that's the IRQ number sitting in the 0-th index
of our irqs_table array.
This, however, is safe at least for current implementations of
CPSW so we will refrain from making the check smarter (and, as
a side-effect, slower) until we actually have a platform where
IRQ lines are swapped.
This patch has been tested for several days with AM335x- and
AM437x-based platforms. AM57x was left out because there are
still pending patches to enable ethernet in mainline for that
platform. A read of the TRM confirms the statement on previous
paragraph.

x86, um: actually mark system call tables readonly
Commit
a074335a370e ("x86, um: Mark system call tables readonly") was
supposed to mark the sys_call_table in UML as RO by adding the const,
but it doesn't have the desired effect as it's nevertheless being placed
into the data section since __cacheline_aligned enforces sys_call_table
being placed into .data..cacheline_aligned instead. We need to use
the ____cacheline_aligned version instead to fix this issue.
Before:
$ nm -v arch/x86/um/sys_call_table_64.o | grep -1 "sys_call_table"
U sys_writev
0000000000000000 D sys_call_table
0000000000000000 D syscall_table_size
After:
$ nm -v arch/x86/um/sys_call_table_64.o | grep -1 "sys_call_table"
U sys_writev
0000000000000000 R sys_call_table

futex_atomic_cmpxchg_inatomic() does not work on UML because
it triggers a copy_from_user() in kernel context.
On UML copy_from_user() can only be used if the kernel was called
by a real user space process such that UML can use ptrace()

qmi_wwan: Set random MAC on devices with buggy fw
Some buggy firmwares export an incorrect MAC address (00:a0:c6:00:00:00). This
makes for example checking devices for random MAC addresses tricky, and you
might end up with multiple network interfaces with the same address.
This patch tries to fix, or at least improve, the situation by setting the MAC
address of devices with this firmware bug to a random address. I tested the
patch with two devices that has this firmware bug (Huawei E398 and E392), and
network traffic worked fine after changing the address.

tcp: Do not apply TSO segment limit to non-TSO packets
Thomas Jarosch reported IPsec TCP stalls when a PMTU event occurs.
In fact the problem was completely unrelated to IPsec. The bug is
also reproducible if you just disable TSO/GSO.
The problem is that when the MSS goes down, existing queued packet
on the TX queue that have not been transmitted yet all look like
TSO packets and get treated as such.
This then triggers a bug where tcp_mss_split_point tells us to
generate a zero-sized packet on the TX queue. Once that happens
we're screwed because the zero-sized packet can never be removed
by ACKs.

It's causing severe userspace breakage. Namely, all the utilities from
wireless-utils which are relying on CONFIG_WEXT (which means tools like
'iwconfig', 'iwlist', etc) are not working anymore. There is a 'iw'
utility in newer wireless-tools, which is supposed to be a replacement
for all the "deprecated" binaries, but it's far away from being
massively adopted.
Please see [1] for example of the userspace breakage this is causing.
In addition to that, Larry Finger reports [2] that this patch is also
causing ipw2200 driver being impossible to build.
To me this clearly shows that CONFIG_WEXT is far, far away from being
"deprecated enough" to be removed.

SCSI: fix regression in scsi_send_eh_cmnd()
Commit
ac61d1955934 (scsi: set correct completion code in
scsi_send_eh_cmnd()) introduced a bug. It changed the stored return
value from a queuecommand call, but it didn't take into account that
the return value was used again later on. This patch fixes the bug by
changing the later usage.
There is a big comment in the middle of scsi_send_eh_cmnd() which
does a good job of explaining how the routine works. But it mentions
a "rtn = FAILURE" value that doesn't exist in the code. This patch
adjusts the code to match the comment (I assume the comment is right
and the code is wrong).
This fixes Bugzilla #88341.
