[ Upstream commit b74cd55aa9a9d0aca760028a51343ec79812e410 ]
First, function gfs2_ail_flush_reqd checks the SDF_FORCE_AIL_FLUSH flag
to determine if an AIL flush should be forced in low-memory situations.
However, it also immediately clears the flag, and when called repeatedly
as in function gfs2_logd, the flag will be lost. Fix that by pulling
the SDF_FORCE_AIL_FLUSH flag check out of gfs2_ail_flush_reqd.
Second, function gfs2_writepages sets the SDF_FORCE_AIL_FLUSH flag
whether or not enough pages were written. If enough pages could be
written, flushing the AIL is unnecessary, though.
Third, gfs2_writepages doesn't wake up logd after setting the
SDF_FORCE_AIL_FLUSH flag, so it can take a long time for logd to react.
It would be preferable to wake up logd, but that hurts the performance
of some workloads and we don't quite understand why so far, so don't
wake up logd so far.

commit 915d975b2ffa58a14bfcf16fafe00c41315949ff upstream.
Blamed commit changed:
ptr = kmalloc(size);
if (ptr)
size = ksize(ptr);
to:
size = kmalloc_size_roundup(size);
ptr = kmalloc(size);
This allowed various crash as reported by syzbot [1]
and Kyle Zeng.
Problem is that if @size is bigger than 0x80000001,
kmalloc_size_roundup(size) returns 2^32.
kmalloc_reserve() uses a 32bit variable (obj_size),
so 2^32 is truncated to 0.
kmalloc(0) returns ZERO_SIZE_PTR which is not handled by
skb allocations.
Following trace can be triggered if a netdev->mtu is set
close to 0x7fffffff
We might in the future limit netdev->mtu to more sensible
limit (like KMALLOC_MAX_SIZE).
This patch is based on a syzbot report, and also a report
and tentative fix from Kyle Zeng.

commit 72d00e560d10665e6139c9431956a87ded6e9880 upstream.
Since commit b09c68dc57 ("clk: imx: pll14xx: Support dynamic rates"),
the driver has the ability to dynamically compute PLL parameters to
approximate the requested rates. This is not always used, because the
logic is as follows:
- Check if the target rate is hardcoded in the frequency table
- Check if varying only kdiv is possible, so switch over is glitch free
- Compute rate dynamically by iterating over pdiv range
If we skip the frequency table for the 1443x PLL, we find that the
computed values differ to the hardcoded ones. This can be valid if the
hardcoded values guarantee for example an earlier lock-in or if the
divisors are chosen, so that other important rates are more likely to
be reached glitch-free.
For rates (393216000 and 361267200, this doesn't seem to be the case:
They are only approximated by existing parameters (393215995 and
361267196 Hz, respectively) and they aren't reachable glitch-free from
other hardcoded frequencies. Dropping them from the table allows us
to lock-in to these frequencies exactly.
This is immediately noticeable because they are the assigned-clock-rates
for IMX8MN_AUDIO_PLL1 and IMX8MN_AUDIO_PLL2, respectively and a look
into clk_summary so far showed that they were a few Hz short of the target:
imx8mn-board:~# grep audio_pll[12]_out /sys/kernel/debug/clk/clk_summary
audio_pll2_out 0 0 0 361267196 0 0 50000 N
audio_pll1_out 1 1 0 393215995 0 0 50000 Y
and afterwards:
imx8mn-board:~# grep audio_pll[12]_out /sys/kernel/debug/clk/clk_summary
audio_pll2_out 0 0 0 361267200 0 0 50000 N
audio_pll1_out 1 1 0 393216000 0 0 50000 Y
This change is equivalent to adding following hardcoded values:
/* rate mdiv pdiv sdiv kdiv */
PLL_1443X_RATE(393216000, 655, 5, 3, 23593),
PLL_1443X_RATE(361267200, 497, 33, 0, -16882),

test_pages() tests the page allocator by calling alloc_pages() with
different orders up to order 10.
However, different architectures and platforms support different maximum
contiguous allocation sizes. The default maximum allocation order
(MAX_ORDER) is 10, but architectures can use CONFIG_ARCH_FORCE_MAX_ORDER
to override this. On platforms where this is less than 10, test_meminit()
will blow up with a WARN(). This is expected, so let's not do that.
Replace the hardcoded "10" with the MAX_ORDER macro so that we test
allocations up to the expected platform limit.

CONFIG_PAGE_TABLE_CHECK is enabled), it may crash the kernel.
So fix it. And inline __split_vmemmap_huge_pmd() since it only has one

commit 86327e8eb94c52eca4f93cfece2e29d1bf52acbf upstream.
kmem.limit_in_bytes (v1 way to limit kernel memory usage) has been
deprecated since 58056f7750 ("memcg, kmem: further deprecate
kmem.limit_in_bytes") merged in 5.16. We haven't heard about any serious
users since then but it seems that the mere presence of the file is
causing more harm thatn good. We (SUSE) have had several bug reports from
customers where Docker based containers started to fail because a write to
kmem.limit_in_bytes has failed.
This was unexpected because runc code only expects ENOENT (kmem disabled)
or EBUSY (tasks already running within cgroup). So a new error code was
unexpected and the whole container startup failed. This has been later
addressed by
52390d6804
so current Docker runtimes do not suffer from the problem anymore. There
are still older version of Docker in use and likely hard to get rid of
completely.
Address this by wiping out the file completely and effectively get back to
pre 4.5 era and CONFIG_MEMCG_KMEM=n configuration.
I would recommend backporting to stable trees which have picked up
58056f7750 ("memcg, kmem: further deprecate kmem.limit_in_bytes").

The ChannelSequence field in the SMB3 header is supposed to be
increased after reconnect to allow the server to distinguish
requests from before and after the reconnect. We had always
been setting it to zero. There are cases where incrementing
ChannelSequence on requests after network reconnects can reduce
the chance of data corruptions.

It looks like txdv-skew-psec is a typo from a copy+paste. txdv-skew-psec
is not present in the PHY bindings nor is it in the driver.
Correct to txen-skew-psec which is clearly what it was meant to be.
Given that the default for txen-skew-psec is 0, and the device tree is
only trying to set it to 0 anyway, there should not be any functional

commit d900d9a435ca95a386f49424f3689cd17ec201da upstream.
Sample rate conversions for rates greater than 48kHz are found to be
failing. It means x->y conversions fail when either x or y is greater
than 48kHz.
This happens because, tegra210_sfc_rate_to_idx() returns incorrect
index for rates greater than 48kHz. This actually depends on the
tegra210_sfc_rates[] array and it is not in sync with frequency
values of SFC TX/RX register. To be precise, 64kHz entry is missing
in above array defined in the driver. Due to this wrong index is
returned and this results in incorrect programming of coefficients.
To fix this, align the tegra210_sfc_rates[] array with SFC register
specification and thus add 64kHz entry to it. Also, the coefficient
table is updated to reflect that none of the conversions are supported
for 64kHz.

// req->rq_next = NULL

// rq->queuelist->next == NULL

Fix these problems by setting requests state to MQ_RQ_COMPLETE under
nq->poll_lock protection, in which null_timeout_rq() can safely detect
this race and early return.
Note this patch just fix the kernel panic when request timeout happen.

Link up failure occurred where driver failed to see certain events from FW
indicating link up (AEN 8011) and fabric login completion (AEN 8014).
Without these 2 events, driver would not proceed forward to scan the
fabric. The cause of this is due to delay in the receive of interrupt for
Mailbox 60 that causes qla to set the fw_started flag late. The late
setting of this flag causes other interrupts to be dropped. These dropped
interrupts happen to be the link up (AEN 8011) and fabric login completion
(AEN 8014).

commands associated to the TMF. At the end of the qpair flush, a Marker is

confusion for FW.
Instead, 1 flush is sent to FW. Driver would wait for FW to go through all
the I/Os on each qpair to be read then return. Driver then closes out the
