[ Upstream commit 69eb7765b9 ]
ocfs2_duplicate_clusters_by_page() may crash if one of the extent's pages
is dirty. When a page has not been written back, it is still in dirty
state. If ocfs2_duplicate_clusters_by_page() is called against the dirty
page, the crash happens.
To fix this bug, we can just unlock the page and wait until the page until
its not dirty.
The following is the backtrace:

[ Upstream commit 0781168e23 ]
In yam_ioctl(), the concrete ioctl command is firstly copied from the
user-space buffer 'ifr->ifr_data' to 'ioctl_cmd' and checked through the
following switch statement. If the command is not as expected, an error
code EINVAL is returned. In the following execution the buffer
'ifr->ifr_data' is copied again in the cases of the switch statement to
specific data structures according to what kind of ioctl command is
requested. However, after the second copy, no re-check is enforced on the
newly-copied command. Given that the buffer 'ifr->ifr_data' is in the user
space, a malicious user can race to change the command between the two
copies. This way, the attacker can inject inconsistent data and cause
undefined behavior.
This patch adds a re-check in each case of the switch statement if there is
a second copy in that case, to re-check whether the command obtained in the
second copy is the same as the one in the first copy. If not, an error code
EINVAL will be returned.

In cxgb_extension_ioctl(), the command of the ioctl is firstly copied from
the user-space buffer 'useraddr' to 'cmd' and checked through the
switch statement. If the command is not as expected, an error code
EOPNOTSUPP is returned. In the following execution, i.e., the cases of the
switch statement, the whole buffer of 'useraddr' is copied again to a
specific data structure, according to what kind of command is requested.
However, after the second copy, there is no re-check on the newly-copied
command. Given that the buffer 'useraddr' is in the user space, a malicious
user can race to change the command between the two copies. By doing so,
the attacker can supply malicious data to the kernel and cause undefined
behavior.
This patch adds a re-check in each case of the switch statement if there is

[ Upstream commit 2d52527e80 ]
the be2net implementation of .ndo_tunnel_{add,del}() changes the value of
NETIF_F_GSO_UDP_TUNNEL bit in 'features' and 'hw_features', but it forgets
to call netdev_features_change(). Moreover, ethtool setting for that bit
can potentially be reverted after a tunnel is added or removed.
GSO already does software segmentation when 'hw_enc_features' is 0, even
if VXLAN offload is turned on. In addition, commit 096de2f83e ("benet:
stricter vxlan offloading check in be_features_check") avoids hardware
segmentation of non-VXLAN tunneled packets, or VXLAN packets having wrong
destination port. So, it's safe to avoid flipping the above feature on
addition/deletion of VXLAN tunnels.

If CONFIG_WW_MUTEX_SELFTEST=y is enabled, booting an image

traceback if 8 CPUs are enabled:
DEBUG_LOCKS_WARN_ON(__owner_task(owner) != current)
WARNING: CPU: 2 PID: 537 at kernel/locking/mutex.c:1033 __mutex_unlock_slowpath+0x1a8/0x2e0

If requesting b_mutex fails with -EDEADLK, the error variable
is reassigned to the return value from calling ww_mutex_lock
on a_mutex again. If this call fails, a_mutex is not locked.
It is, however, unconditionally unlocked subsequently, causing
the reported warning. Fix the problem by using two error variables.
With this change, the selftest still fails as follows:
cyclic deadlock not resolved, ret[7/8] = -35

Fix a commit 4bcc595ccd ("printk: reinstate KERN_CONT for printing

the adapter identification message to be split between two lines, e.g.:

[ Upstream commit cd6fb677ce ]
Some of the scheduling tracepoints allow the perf_tp_event
code to write to ring buffer under different cpu than the
code is running on.
This results in corrupted ring buffer data demonstrated in
following perf commands:
# perf record -e 'sched:sched_switch,sched:sched_wakeup' perf bench sched messaging
# Running 'sched/messaging' benchmark:
# 20 sender and receiver processes per group
# 10 groups == 400 processes run
Total time: 0.383 [sec]
[ perf record: Woken up 8 times to write data ]
0x42b890 [0]: failed to process type: -1765585640
[ perf record: Captured and wrote 4.825 MB perf.data (29669 samples) ]
# perf report --stdio
0x42b890 [0]: failed to process type: -1765585640
The reason for the corruption are some of the scheduling tracepoints,
that have __perf_task dfined and thus allow to store data to another
cpu ring buffer:
sched_waking
sched_wakeup
sched_wakeup_new
sched_stat_wait
sched_stat_sleep
sched_stat_iowait
sched_stat_blocked
The perf_tp_event function first store samples for current cpu
related events defined for tracepoint:
hlist_for_each_entry_rcu(event, head, hlist_entry)
perf_swevent_event(event, count, &data, regs);
And then iterates events of the 'task' and store the sample
for any task's event that passes tracepoint checks:
ctx = rcu_dereference(task->perf_event_ctxp[perf_sw_context]);
list_for_each_entry_rcu(event, &ctx->event_list, event_entry) {
if (event->attr.type != PERF_TYPE_TRACEPOINT)
continue;
if (event->attr.config != entry->type)
continue;
perf_swevent_event(event, count, &data, regs);
}
Above code can race with same code running on another cpu,
ending up with 2 cpus trying to store under the same ring
buffer, which is specifically not allowed.
This patch prevents the problem, by allowing only events with the same
current cpu to receive the event.
NOTE: this requires the use of (per-task-)per-cpu buffers for this
feature to work; perf-record does this.

[ Upstream commit a173f066c7 ]
For starters, the bridge netfilter code registers operations that
are invoked any time nh_hook is called. Specifically, ip_sabotage_in
watches for nested calls for NF_INET_PRE_ROUTING when a bridge is in
the stack.
Packet wise, the bridge netfilter hook runs first. br_nf_pre_routing
allocates nf_bridge, sets in_prerouting to 1 and calls NF_HOOK for
NF_INET_PRE_ROUTING. It's finish function, br_nf_pre_routing_finish,
then resets in_prerouting flag to 0 and the packet continues up the
stack. The packet eventually makes it to the VRF driver and it invokes
nf_hook for NF_INET_PRE_ROUTING in case any rules have been added against
the vrf device.
Because of the registered operations the call to nf_hook causes
ip_sabotage_in to be invoked. That function sees the nf_bridge on the
skb and that in_prerouting is not set. Thinking it is an invalid nested
call it steals (drops) the packet.
Update ip_sabotage_in to recognize that the bridge or one of its upper
devices (e.g., vlan) can be enslaved to a VRF (L3 master device) and
allow the packet to go through the nf_hook a second time.

[ Upstream commit 3a58ac65e2 ]
IO_SPACE_LIMIT is the ending address of the PCI IO space, i.e
something like 0xfffff (and not 0x100000).
Therefore, when offset = 0xf0000 is passed as argument, this function
fails even though the offset + SZ_64K fits below the
IO_SPACE_LIMIT. This makes the last chunk of 64 KB of the I/O space
not usable as it cannot be mapped.
This patch fixes that by substracing 1 to offset + SZ_64K, so that we
compare the addrss of the last byte of the I/O space against
IO_SPACE_LIMIT instead of the address of the first byte of what is
after the I/O space.

Since commit 222d7dbd25 ("net: prevent dst uses after free")
skb_dst_force() might clear the dst_entry attached to the skb.
The xfrm code don't expect this to happen, so we crash with
a NULL pointer dereference in this case. Fix it by checking
skb_dst(skb) for NULL after skb_dst_force() and drop the packet
in cast the dst_entry was cleared.

[ Upstream commit c420551057 ]
TX status reporting to ieee80211s is through ieee80211s_update_metric.
There are two problems about ieee80211s_update_metric:
1. The purpose is to estimate the fail probability
to a specific link. No need to restrict to data frame.
2. Current implementation does not work if wireless driver does not
pass tx_status with skb.
Fix this by removing ieee80211_is_data condition, passing
ieee80211_tx_status directly to ieee80211s_update_metric, and
putting it in both __ieee80211_tx_status and ieee80211_tx_status_ext.

[ Upstream commit 119f94a6fe ]
cfg80211_get_bss_channel() is used to update the RX channel based on the
available frame payload information (channel number from DSSS Parameter
Set element or HT Operation element). This is needed on 2.4 GHz channels
where frames may be received on neighboring channels due to overlapping
frequency range.
This might of some use on the 5 GHz band in some corner cases, but
things are more complex there since there is no n:1 or 1:n mapping
between channel numbers and frequencies due to multiple different
starting frequencies in different operating classes. This could result
in ieee80211_channel_to_frequency() returning incorrect frequency and
ieee80211_get_channel() returning incorrect channel information (or
indication of no match). In the previous implementation, this could
result in some scan results being dropped completely, e.g., for the 4.9
GHz channels. That prevented connection to such BSSs.
Fix this by using the driver-provided channel pointer if
ieee80211_get_channel() does not find matching channel data for the
channel number in the frame payload and if the scan is done with 5 MHz
or 10 MHz channel bandwidth. While doing this, also add comments
describing what the function is trying to achieve to make it easier to
understand what happens here and why.

[ Upstream commit 6eae4a6c2b ]
In our environment running lots of mesh nodes, we are seeing the
pending queue hang periodically, with the debugfs queues file showing
lines such as:
00: 0x00000000/348
i.e. there are a large number of frames but no stop reason set.
One way this could happen is if queue processing from the pending
tasklet exited early without processing all frames, and without having
some future event (incoming frame, stop reason flag, ...) to reschedule
it.
Exactly this can occur today if ieee80211_tx() returns false due to
packet drops or power-save buffering in the tx handlers. In the
past, this function would return true in such cases, and the change
to false doesn't seem to be intentional. Fix this case by reverting
to the previous behavior.

As the user space may rely on the TX_STATUS to kick its state

iterates in xfrm_input() and applies each transform in turn,

This patch resets the transport header back to network header
only after the last transformation so that subsequent xfrms
can find the correct transport header.

__xfrm6_output, causing it to fail to transmit but not free the skb, causing a
leak of skb, and consequentially a leak of dst references.
After running pmtu.sh, that shows as failure to unregister devices in a namespace:
