The current ring buffer logic checks to see if the updating of the event
buffer was interrupted, and if it is, it will try to fix up the before stamp
with the write stamp to make them equal again. This logic is flawed, because
if it is not interrupted, the two are guaranteed to be different, as the
current event just updated the before stamp before allocation. This
guarantees that the next event (this one or another interrupting one) will
think it interrupted the time updates of a previous event and inject an
absolute time stamp to compensate.The correct logic is to always update the timestamps when traversing to a
new sub buffer.Cc: stable@vger.kernel.org

On powerpc, kprobe-direct.tc triggered FTRACE_WARN_ON() in
ftrace_get_addr_new() followed by the below message:

With 5.9 kernel on ARM64, I found ftrace_dump output was broken but
it had no problem with normal output "cat /sys/kernel/debug/tracing/trace".With investigation, it seems coping the data into temporal buffer seems to
break the align binary printf expects if the static buffer is not aligned
with 4-byte. IIUC, get_arg in bstr_printf expects that args has already
right align to be decoded and seq_buf_bprintf says ``the arguments are saved
in a 32bit word array that is defined by the format string constraints``.
So if we don't keep the align under copy to temporal buffer, the output
will be broken by shifting some bytes.This patch fixes it.

In the slow path of __rb_reserve_next() a nested event(s) can happen
between evaluating the timestamp delta of the current event and updating
write_stamp via local_cmpxchg(); in this case the delta is not valid
anymore and it should be set to 0 (same timestamp as the interrupting
event), since the event that we are currently processing is not the last
event in the buffer.Link: https://lkml.kernel.org/r/X8IVJcp1gRE+FJCJ@xps-13-7390

The write stamp, used to calculate deltas between events, was updated with
the stale "ts" value in the "info" structure, and not with the updated "ts"
variable. This caused the deltas between events to be inaccurate, and when
crossing into a new sub buffer, had time go backwards.Link: https://lkml.kernel.org/r/20201124223917.795844-1-elavila@google.com

Pull drm fixes from Dave Airlie:
"Unfortunately this has a bit of thanksgiving stuffing in it, as it a
bit larger (at least the vc4 patches) than I like at this point in
time.The main thing is it has a bunch of regressions fixes for reports in
the last couple of weeks, ast, nouveau and the amdgpu ttm init fix,
along with the usual selection of amdgpu and i915 fixes.The vc4 fixes are a few but they are fixes and the nastiest one is a
fix for when you have a 2.4Ghz Wifi and a HDMI signal with a clock in
that range and there isn't enough shielding and interference happen
between the two, the fix adjusts the mode clock to try and avoid the
wifi channels in that case.Hopefully you can merge this between turkey slices, and next week
should be quieter.ast:

====================
pull-request: can 2020-11-27The first patch is by me and target the gs_usb driver and fixes the endianess
problem with candleLight firmware.Another patch by me for the mcp251xfd driver add sanity checking to bail out if
no IRQ is configured.The next three patches target the m_can driver. A patch by me removes the
hardcoded IRQF_TRIGGER_FALLING from the request_threaded_irq() as this clashes
with the trigger level specified in the DT. Further a patch by me fixes the
nominal bitiming tseg2 min value for modern m_can cores. Pankaj Sharma's patch
add support for cores version 3.3.x.The last patch by Oliver Hartkopp is for af_can and converts a WARN() into a
pr_warn(), which is triggered by the syzkaller. It was able to create a
situation where the closing of a socket runs simultaneously to the notifier
call chain for removing the CAN network device in use.* tag 'linux-can-fixes-for-5.10-20201127' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can:

When setting sk_err, set it to ee_errno, not ee_origin.
Commit f5f99309fa74 ("sock: do not set sk_err in
sock_dequeue_err_skb") disabled updating sk_err on errq dequeue,
which is correct for most error types (origins):- sk->sk_err = err;
Commit 38b257938ac6 ("sock: reset sk_err when the error queue is
empty") reenabled the behavior for IMCP origins, which do require it:+ if (icmp_next)
+ sk->sk_err = SKB_EXT_ERR(skb_next)->ee.ee_origin;But read from ee_errno.

If an msk listener receives an MPJ carrying an invalid token, it
will zero the request socket msk entry. That should later
cause fallback and subflow reset - as per RFC - at
subflow_syn_recv_sock() time due to failing hmac validation.Since commit 4cf8b7e48a09 ("subflow: introduce and use
mptcp_can_accept_new_subflow()"), we unconditionally dereference
- in mptcp_can_accept_new_subflow - the subflow request msk
before performing hmac validation. In the above scenario we
hit a NULL ptr dereference.Address the issue doing the hmac validation earlier.

Currently, the openvswitch module is not accepting the correctly formated
netlink message for the TTL decrement action. For both setting and getting
the dec_ttl action, the actions should be nested in the
OVS_DEC_TTL_ATTR_ACTION attribute as mentioned in the openvswitch.h uapi.When the original patch was sent, it was tested with a private OVS userspace
implementation. This implementation was unfortunately not upstreamed and
reviewed, hence an erroneous version of this patch was sent out.Leaving the patch as-is would cause problems as the kernel module could
interpret additional attributes as actions and vice-versa, due to the
actions not being encapsulated/nested within the actual attribute, but
being concatinated after it.Fixes: 744676e77720 ("openvswitch: add TTL decrement action")

Pull arm64 fixes from Will Deacon:
"The main changes are relating to our handling of access/dirty bits,
where our low-level page-table helpers could lead to stale young
mappings and loss of the dirty bit in some cases (the latter has not
been observed in practice, but could happen when clearing "soft-dirty"
if we enabled that). These were posted as part of a larger series, but
the rest of that is less urgent and needs a v2 which I'll get to
shortly.In other news, we've now got a set of fixes to resolve the
lockdep/tracing problems that have been plaguing us for a while, but
they're still a bit "fresh" and I plan to send them to you next week
after we've got some more confidence in them (although initial CI
results look good).Summary:

- Fix pte_accessible() so that access flag is ignored
- Fix missing header #include
