In jfs_dmap.c at line 381, BLKTODMAP is used to get a logical block
number inside dbFree(). db_l2nbperpage, which is the log2 number of
blocks per page, is passed as an argument to BLKTODMAP which uses it
for shifting.
Syzbot reported a shift out-of-bounds crash because db_l2nbperpage is
too big. This happens because the large value is set without any
validation in dbMount() at line 181.
Thus, make sure that db_l2nbperpage is correct while mounting.
Max number of blocks per page = Page size / Min block size
=> log2(Max num_block per page) = log2(Page size / Min block size)
= log2(Page size) - log2(Min block size)
=> Max db_l2nbperpage = L2PSIZE - L2MINBLOCKSIZE

[BUG]
David reported an ASSERT() get triggered during fio load on 8 devices
with data/raid6 and metadata/raid1c3:
fio --rw=randrw --randrepeat=1 --size=3000m \
--bsrange=512b-64k --bs_unaligned \
--ioengine=libaio --fsync=1024 \
--name=job0 --name=job1 \
The ASSERT() is from rbio_add_bio() of raid56.c:
ASSERT(orig_logical >= full_stripe_start &&
orig_logical + orig_len <= full_stripe_start +
rbio->nr_data * BTRFS_STRIPE_LEN);
Which is checking if the target rbio is crossing the full stripe
boundary.

[CAUSE]
Commit a97699d1d610 ("btrfs: replace map_lookup->stripe_len by
BTRFS_STRIPE_LEN") changes how we calculate the map length, to reduce
u64 division.
Function btrfs_max_io_len() is to get the length to the stripe boundary.
It calculates the full stripe start offset (inside the chunk) by the
following code:
*full_stripe_start =
rounddown(*stripe_nr, nr_data_stripes(map)) <<
BTRFS_STRIPE_LEN_SHIFT;
The calculation itself is fine, but the value returned by rounddown() is
dependent on both @stripe_nr (which is u32) and nr_data_stripes() (which
returned int).
Thus the result is also u32, then we do the left shift, which can
overflow u32.
If such overflow happens, @full_stripe_start will be a value way smaller
than @offset, causing later "full_stripe_len - (offset -
*full_stripe_start)" to underflow, thus make later length calculation to
have no stripe boundary limit, resulting a write bio to exceed stripe
boundary.
There are some other locations like this, with a u32 @stripe_nr got left
shift, which can lead to a similar overflow.
[FIX]
Fix all @stripe_nr with left shift with a type cast to u64 before the
left shift.
Those involved @stripe_nr or similar variables are recording the stripe
number inside the chunk, which is small enough to be contained by u32,
but their offset inside the chunk can not fit into u32.
Thus for those specific left shifts, a type cast to u64 is necessary so
this patch does not touch them and the code will be cleaned up in the
future to keep the fix minimal.

Attempt to handle cases such as with a downstream port of the ASMedia
ASM2824 PCIe switch where link training never completes and the link
continues switching between speeds indefinitely with the data link layer
never reaching the active state.
It has been observed with a downstream port of the ASMedia ASM2824 Gen 3
switch wired to the upstream port of the Pericom PI7C9X2G304 Gen 2 switch,
using a Delock Riser Card PCI Express x1 > 2 x PCIe x1 device, P/N 41433,
wired to a SiFive HiFive Unmatched board. In this setup the switches
should negotiate a link speed of 5.0GT/s, falling back to 2.5GT/s if
necessary.
Instead the link continues oscillating between the two speeds, at the rate
of 34-35 times per second, with link training reported repeatedly active
~84% of the time. Limiting the target link speed to 2.5GT/s with the
upstream ASM2824 device makes the two switches communicate correctly.
Removing the speed restriction afterwards makes the two devices switch to
5.0GT/s then.
Make use of these observations and detect the inability to train the link
by checking for the Data Link Layer Link Active status bit being off while
the Link Bandwidth Management Status indicating that hardware has changed
the link speed or width in an attempt to correct unreliable link operation.
Restrict the speed to 2.5GT/s then with the Target Link Speed field,
request a retrain and wait 200ms for the data link to go up. If this is
successful, lift the restriction, letting the devices negotiate a higher
speed.
Also check for a 2.5GT/s speed restriction the firmware may have already
arranged and lift it too with ports of devices known to continue working
afterwards (currently only ASM2824), that already report their data link
being up.

call almost identical code in pcie_wait_for_link_status() instead. This
reduces the lower bound on the polling interval from 10ms to 1ms, possibly

sort() in Linux is based on heapsort which is not a stable sort
algorithm - equal elements are being reordered. For reserved memory in
the device tree this happens mainly for dynamic allocations: They do not
have an address to sort with, so they are reordered somewhat randomly
when adding/removing other unrelated reserved memory nodes.
Functionally this is not a big problem, but it's confusing during
development when all the addresses change after adding unrelated
reserved memory nodes.
Make the order stable by sorting dynamic allocations according to
the node order in the device tree. Static allocations are not affected
by this because they are still sorted by their (fixed) address.

Right now dynamic reserved memory regions are allocated either
bottom-up or top-down, depending on the memblock setting of the
architecture. This is fine when the address is arbitrary. However,
when using "alloc-ranges" the regions are often placed somewhere
in the middle of (free) RAM, even if the range starts or ends next
to another (static) reservation.
Try to detect this situation, and choose explicitly between bottom-up
or top-down to allocate the memory close to the other reservations:
1. If the "alloc-range" starts at the end or inside an existing
reservation, use bottom-up.
2. If the "alloc-range" ends at the start or inside an existing
reservation, use top-down.
3. If both or none is the case, keep the current
(architecture-specific) behavior.
There are plenty of edge cases where only a more complex algorithm
would help, but even this simple approach helps in many cases to keep
the reserved memory (and therefore also the free memory) contiguous.

Using the old mount api to remount an overlayfs superblock via
mount(MS_REMOUNT) all mount options will be silently ignored. For
example, if you create an overlayfs mount:
mount -t overlay overlay -o lowerdir=/mnt/a:/mnt/b,upperdir=/mnt/upper,workdir=/mnt/work /mnt/merged
and then issue a remount via:
# force mount(8) to use mount(2)
export LIBMOUNT_FORCE_MOUNT2=always
mount -t overlay overlay -o remount,WOOTWOOT,lowerdir=/DOESNT-EXIST /mnt/merged
with completely nonsensical mount options whatsoever it will succeed
nonetheless. This prevents us from every changing any mount options we
might introduce in the future that could reasonably be changed during a
remount.
We don't need to carry this issue into the new mount api port. Similar
to FUSE we can use the fs_context::oldapi member to figure out that this
is a request coming through the legacy mount api. If we detect it we
continue silently ignoring all mount options.
But for the new mount api we simply report that mount options cannot
currently be changed. This will allow us to potentially alter mount
properties for new or even old properties. It any case, silently
ignoring everything is not something new apis should do.

in arch_uprobe_{post,abort}_xol() accordingly, otherwise the save operation
is meaningless, this change is similar with x86 and powerpc.

Attempt VMA lock-based page fault handling first, and fall back to the
existing mmap_lock-based handling if that fails.
A simple running the ebizzy benchmark on Lichee Pi 4A shows that
PER_VMA_LOCK can improve the ebizzy benchmark by about 32.68%. In
theory, the more CPUs, the bigger improvement, but I don't have any
HW platform which has more than 4 CPUs.
This is the riscv variant of "x86/mm: try VMA lock-based page fault
handling first".

A recent patch incorrectly did not include IB_ACCESS_RELAXED_ORDERING in
the list of supported access flags for the rxe driver. The driver actually
does nothing related to relaxed ordering but it causes no problems to
include it as supported but with no effect. This change caused ib_send_bw
and friends to not run correctly.
The correct approach is for the driver to allow any of the optional access
flags and otherwise ignore them. This patch adds IB_ACCESS_OPTIONAL to the
list of rxe supported flags.

The current way how lowcomms is configured is due configfs entries. Each
comms configfs entry will create a lowcomms connection. Even the local
connection itself will be stored as a lowcomms connection, although most
functionality for a local lowcomms connection struct is not necessary.
Now in some scenarios we will see that dlm_controld reports a -EEXIST
when configure a node via configfs:
... /sys/kernel/config/dlm/cluster/comms/1/addr: write failed: 17 -1
Doing a:
cat /sys/kernel/config/dlm/cluster/comms/1/addr_list
reported nothing. This was being seen on cluster with nodeid 1 and it's
local configuration. To be sure the configfs entries are in sync with
lowcomms connection structures we always call dlm_midcomms_close() to be
sure the lowcomms connection gets removed when the configfs entry gets
dropped.
Before commit 07ee38674a0b ("fs: dlm: filter ourself midcomms calls") it
was just doing this by accident and the filter by doing:
if (nodeid == dlm_our_nodeid())
return 0;
inside dlm_midcomms_close() was never been hit because drop_comm() sets
local_comm to NULL and cause that dlm_our_nodeid() returns always the
invalid nodeid 0.

interrupt
The hibernation feature enabled for Xilinx Versal NET SoC in DWC3 IP.
As the DWC3 IP supports the hibernation feature, to handle the wakeup
or hibernation interrupt, add host mode "wakeup" interrupt-names
optional property in the binding schema to capture remote-wakeup and
connect/ disconnect event in the hibernation state and increased maxItems
to 4 for the interrupts and interrupt-names property.
We have a dedicated IRQ line specifically for the hibernation feature.
When the "wakeup" IRQ line is triggered, it initiates a hibernation
interrupt, causing the system to wake up from the hibernation state.
