platform/x86: ideapad-laptop: Stop sending KEY_TOUCHPAD_TOGGLE
Commit
5829f8a897e4 ("platform/x86: ideapad-laptop: Send
KEY_TOUCHPAD_TOGGLE on some models") made ideapad-laptop send
KEY_TOUCHPAD_TOGGLE when we receive an ACPI notify with VPC event bit 5 set
and the touchpad-state has not been changed by the EC itself already.
This was done under the assumption that this would be good to do to make
the touchpad-toggle hotkey work on newer models where the EC does not
toggle the touchpad on/off itself (because it is not routed through
the PS/2 controller, but uses I2C).
But it turns out that at least some models, e.g. the Yoga 7-15ITL5 the EC
triggers an ACPI notify with VPC event bit 5 set on resume, which would
now cause a spurious KEY_TOUCHPAD_TOGGLE on resume to which the desktop
environment responds by disabling the touchpad in software, breaking
the touchpad (until manually re-enabled) on resume.
It was never confirmed that sending KEY_TOUCHPAD_TOGGLE actually improves
things on new models and at least some new models like the Yoga 7-15ITL5
don't have a touchpad on/off toggle hotkey at all, while still sending
ACPI notify events with VPC event bit 5 set.
So it seems best to revert the change to send KEY_TOUCHPAD_TOGGLE when
receiving an ACPI notify events with VPC event bit 5 and the touchpad
state as reported by the EC has not changed.
Note this is not a full revert the code to cache the last EC touchpad
state is kept to avoid sending spurious KEY_TOUCHPAD_ON / _OFF events
on resume.

dm: fix __send_duplicate_bios() to always allow for splitting IO
Commit
7dd76d1feec70 ("dm: improve bio splitting and associated IO
accounting") only called setup_split_accounting() from
__send_duplicate_bios() if a single bio were being issued. But the case
where duplicate bios are issued must call it too.
Otherwise the bio won't be split and resubmitted (via recursion through
block core back to DM) to submit the later portions of a bio (which may
map to an entirely different target).
For example, when discarding an entire DM striped device with the
following DM table:
vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048
vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048
Before (broken, discards the first striped target's devices twice):
device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872
device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872
device-mapper: striped: target_stripe=0, bdev=7:0, start=2049 len=22528
device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=22528
After (works as expected):

dm: fix improper splitting for abnormal bios
"Abnormal" bios include discards, write zeroes and secure erase. By no
longer passing the calculated 'len' pointer, commit
7dd06a2548b2 ("dm:
allow dm_accept_partial_bio() for dm_io without duplicate bios") took a
senseless approach to disallowing dm_accept_partial_bio() from working
for duplicate bios processed using __send_duplicate_bios().
It inadvertently and incorrectly stopped the use of 'len' when
initializing a target's io (in alloc_tio). As such the resulting tio
could address more area of a device than it should.
For example, when discarding an entire DM striped device with the
following DM table:
vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048

Then on mvneta_open(), we call mvneta_setup_txqs(), which starts
allocating memory. On memory allocation failure, mvneta_cleanup_txqs()
will walk all the queues freeing any non-NULL pointers - which includes
pointers that were previously freed in mvneta_stop().
Fix this by setting these pointers to NULL to prevent double-freeing
of the same memory.

net: dsa: sync unicast and multicast addresses for VLAN filters too
If certain conditions are met, DSA can install all necessary MAC
addresses on the CPU ports as FDB entries and disable flooding towards
the CPU (we call this RX filtering).
There is one corner case where this does not work.
ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up
ip link set swp0 master br0 && ip link set swp0 up
ip link add link swp0 name swp0.100 type vlan id 100
ip link set swp0.100 up && ip addr add 192.168.100.1/24 dev swp0.100
Traffic through swp0.100 is broken, because the bridge turns on VLAN
filtering in the swp0 port (causing RX packets to be classified to the
FDB database corresponding to the VID from their 802.1Q header), and
although the 8021q module does call dev_uc_add() towards the real
device, that API is VLAN-unaware, so it only contains the MAC address,
not the VID; and DSA's current implementation of ndo_set_rx_mode() is
only for VID 0 (corresponding to FDB entries which are installed in an
FDB database which is only hit when the port is VLAN-unaware).
It's interesting to understand why the bridge does not turn on
IFF_PROMISC for its swp0 bridge port, and it may appear at first glance
that this is a regression caused by the logic in commit
2796d0c648c9
("bridge: Automatically manage port promiscuous mode."). After all,
a bridge port needs to have IFF_PROMISC by its very nature - it needs to
receive and forward frames with a MAC DA different from the bridge
ports' MAC addresses.
While that may be true, when the bridge is VLAN-aware *and* it has a
single port, there is no real reason to enable promiscuity even if that
is an automatic port, with flooding and learning (there is nowhere for
packets to go except to the BR_FDB_LOCAL entries), and this is how the
corner case appears. Adding a second automatic interface to the bridge
would make swp0 promisc as well, and would mask the corner case.
Given the dev_uc_add() / ndo_set_rx_mode() API is what it is (it doesn't
pass a VLAN ID), the only way to address that problem is to install host
FDB entries for the cartesian product of RX filtering MAC addresses and
VLAN RX filters.

====================
fix header length on skb merging
this patchset fixes appending newly arrived skbuff to the last skbuff of
the socket's queue during rx path. Problem fires when we are trying to
append data to skbuff which was already processed in dequeue callback
at least once. Dequeue callback calls function 'skb_pull()' which changes
'skb->len'. In current implementation 'skb->len' is used to update length
in header of last skbuff after new data was copied to it. This is bug,
because value in header is used to calculate 'rx_bytes'/'fwd_cnt' and
thus must be constant during skbuff lifetime. Here is example, we have
two skbuffs: skb0 with length 10 and skb1 with length 4.
1) skb0 arrives, hdr->len == skb->len == 10, rx_bytes == 10
2) Read 3 bytes from skb0, skb->len == 7, hdr->len == 10, rx_bytes == 10
3) skb1 arrives, hdr->len == skb->len == 4, rx_bytes == 14
4) Append skb1 to skb0, skb0 now has skb->len == 11, hdr->len == 11.
But value of 11 in header is invalid.
5) Read whole skb0, update rx_bytes by 11 from skb0's header.
6) At this moment rx_bytes == 3, but socket's queue is empty.
This bug starts to fire since:
commit
077706165717 ("virtio/vsock: don't use skbuff state to account credit")

2) Patch with WARN_ONCE() to catch such problems in future.
3) Patch with test which triggers skb appending logic. It looks like
simple test with several 'send()' and 'recv()', but it checks, that
skbuff appending works ok.

bnx2x: use the right build_skb() helper
build_skb() no longer accepts slab buffers. Since slab use is fairly
uncommon we prefer the drivers to call a separate slab_build_skb()
function appropriately.
bnx2x uses the old semantics where size of 0 meant buffer from slab.
It sets the fp->rx_frag_size to 0 for MTUs which don't fit in a page.
It needs to call slab_build_skb().
This fixes the WARN_ONCE() of incorrect API use seen with bnx2x.

net: ipa: compute DMA pool size properly
In gsi_trans_pool_init_dma(), the total size of a pool of memory
used for DMA transactions is calculated. However the calculation is
done incorrectly.
For 4KB pages, this total size is currently always more than one
page, and as a result, the calculation produces a positive (though
incorrect) total size. The code still works in this case; we just
end up with fewer DMA pool entries than we intended.
Bjorn Andersson tested booting a kernel with 16KB pages, and hit a
null pointer derereference in sg_alloc_append_table_from_pages(),
descending from gsi_trans_pool_init_dma(). The cause of this was
that a 16KB total size was going to be allocated, and with 16KB
pages the order of that allocation is 0. The total_size calculation
yielded 0, which eventually led to the crash.
Correcting the total_size calculation fixes the problem.

nvme-tcp: fix a possible UAF when failing to allocate an io queue
When we allocate a nvme-tcp queue, we set the data_ready callback before
we actually need to use it. This creates the potential that if a stray
controller sends us data on the socket before we connect, we can trigger
the io_work and start consuming the socket.
In this case reported: we failed to allocate one of the io queues, and
as we start releasing the queues that we already allocated, we get
a UAF [1] from the io_work which is running before it should really.
Fix this by setting the socket ops callbacks only before we start the
queue, so that we can't accidentally schedule the io_work in the
initialization phase before the queue started. While we are at it,
rename nvme_tcp_restore_sock_calls to pair with nvme_tcp_setup_sock_ops.

Merge patch series "RISC-V: Fixes for riscv_has_extension[un]likely()'s alternative dependency"
Conor Dooley <conor.dooley@microchip.com> says:
Here's my attempt at fixing both the use of an FPU on XIP kernels and
the issue that Jason ran into where CONFIG_FPU, which needs the
alternatives frame work for has_fpu() checks, could be enabled without
the alternatives actually being present.
For the former, a "slow" fallback that does not use alternatives is
added to riscv_has_extension_[un]likely() that can be used with XIP.
Obviously, we want to make use of Jisheng's alternatives based approach
where possible, so any users of riscv_has_extension_[un]likely() will
want to make sure that they select RISCV_ALTERNATIVE.
If they don't however, they'll hit the fallback path which (should,
sparing a silly mistake from me!) behave in the same way, thus
succeeding silently. Sounds like a
To prevent "depends on !XIP_KERNEL; select RISCV_ALTERNATIVE" spreading
like the plague through the various places that want to check for the
presence of extensions, and sidestep the potential silent "success"
mentioned above, all users RISCV_ALTERNATIVE are converted from selects
to dependencies, with the option being selected for all !XIP_KERNEL
builds.
I know that the VDSO was a key place that Jisheng wanted to use the new
helper rather than static branches, and I think the fallback path
should not cause issues there.

RISC-V: always select RISCV_ALTERNATIVE for non-xip kernels
When moving switch_to's has_fpu() over to using
riscv_has_extension_likely() rather than static branches, the FPU code
gained a dependency on the alternatives framework.
That dependency has now been removed, as riscv_has_extension_ikely() now
contains a fallback path, using __riscv_isa_extension_available(), but
if CONFIG_RISCV_ALTERNATIVE isn't selected when CONFIG_FPU is, has_fpu()
checks will not benefit from the "fast path" that the alternatives
framework provides.
We want to ensure that alternatives are available whenever
riscv_has_extension_[un]likely() is used, rather than silently falling
back to the slow path, but rather than rely on selecting
RISCV_ALTERNATIVE in the myriad of locations that may use
riscv_has_extension_[un]likely(), select it (almost) always instead by
adding it to the main RISCV config entry.
xip kernels cannot make use of the alternatives framework, so it is not
enabled for those configurations, although this is the status quo.
All current sites that select RISCV_ALTERNATIVE are converted to
dependencies on the option instead. The explicit dependencies on
!XIP_KERNEL can be dropped, as RISCV_ALTERNATIVE is not user selectable.

The has_fpu() check, which in turn calls riscv_has_extension_likely(),

As a result, it will malfunction on XIP kernels, as they do not support
the alternatives mechanism.
When alternatives support is not present, fall back to using
__riscv_isa_extension_available() in riscv_has_extension_[un]likely()

After commit

the fbdev emulation code, which now is a drm-client, can only run after
drm_dev_register(). So during backlight registration the connectors are
not probed yet and the drm_connector->status == connected check in
nv50_backlight_init() would now always fail.

Based on a number of tests, it seems that this throttling can be safely
dropped without re-introducing the issues on switch ports that the
tx scheduling changes resolved.

ice: fix invalid check for empty list in ice_sched_assoc_vsi_to_agg()
The code implicitly assumes that the list iterator finds a correct
handle. If 'vsi_handle' is not found the 'old_agg_vsi_info' was
pointing to an bogus memory location. For safety a separate list
iterator variable should be used to make the != NULL check on
'old_agg_vsi_info' correct under any circumstances.
Additionally Linus proposed to avoid any use of the list iterator
variable after the loop, in the attempt to move the list iterator
variable declaration into the macro to avoid any potential misuse after
the loop. Using it in a pointer comparison after the loop is undefined
behavior and should be omitted if possible [1].

ice: add profile conflict check for AVF FDIR
Add profile conflict check while adding some FDIR rules to avoid
unexpected flow behavior, rules may have conflict including:
IPv4 <---> {IPv4_UDP, IPv4_TCP, IPv4_SCTP}
IPv6 <---> {IPv6_UDP, IPv6_TCP, IPv6_SCTP}
For example, when we create an FDIR rule for IPv4, this rule will work
on packets including IPv4, IPv4_UDP, IPv4_TCP and IPv4_SCTP. But if we
then create an FDIR rule for IPv4_UDP and then destroy it, the first
FDIR rule for IPv4 cannot work on pkt IPv4_UDP then.
To prevent this unexpected behavior, we add restriction in software
when creating FDIR rules by adding necessary profile conflict check.

The current implementation causes ice_vsi_update() to update all VSI
fields based on the cached VSI context. This also assumes that the
ICE_AQ_VSI_PROP_Q_OPT_VALID bit is set. This can cause problems if the
VSI context is not correctly synced by the driver. Fix this by only

Also, make sure to save the updated result in the cached VSI context

io_uring/poll: clear single/double poll flags on poll arming
Unless we have at least one entry queued, then don't call into
io_poll_remove_entries(). Normally this isn't possible, but if we
retry poll then we can have ->nr_entries cleared again as we're
setting it up. If this happens for a poll retry, then we'll still have
at least REQ_F_SINGLE_POLL set. io_poll_remove_entries() then thinks
it has entries to remove.
Clear REQ_F_SINGLE_POLL and REQ_F_DOUBLE_POLL unconditionally when
arming a poll request.

loop: LOOP_CONFIGURE: send uevents for partitions
LOOP_CONFIGURE is, as far as I understand it, supposed to be a way to
combine LOOP_SET_FD and LOOP_SET_STATUS64 into a single syscall. When
using LOOP_SET_FD+LOOP_SET_STATUS64, a single uevent would be sent for
each partition found on the loop device after the second ioctl(), but
when using LOOP_CONFIGURE, no such uevent was being sent.
In the old setup, uevents are disabled for LOOP_SET_FD, but not for
LOOP_SET_STATUS64. This makes sense, as it prevents uevents being
sent for a partially configured device during LOOP_SET_FD - they're
only sent at the end of LOOP_SET_STATUS64. But for LOOP_CONFIGURE,
uevents were disabled for the entire operation, so that final
notification was never issued. To fix this, reduce the critical
section to exclude the loop_reread_partitions() call, which causes
the uevents to be issued, to after uevents are re-enabled, matching
the behaviour of the LOOP_SET_FD+LOOP_SET_STATUS64 combination.
I noticed this because Busybox's losetup program recently changed from
using LOOP_SET_FD+LOOP_SET_STATUS64 to LOOP_CONFIGURE, and this broke
my setup, for which I want a notification from the kernel any time a
new partition becomes available.

ACPI: bus: Rework system-level device notification handling
For ACPI drivers that provide a ->notify() callback and set
ACPI_DRIVER_ALL_NOTIFY_EVENTS in their flags, that callback can be
invoked while either the ->add() or the ->remove() callback is running
without any synchronization at the bus type level which is counter to
the common-sense expectation that notification handling should only be
enabled when the driver is actually bound to the device. As a result,
if the driver is not careful enough, it's ->notify() callback may crash
when it is invoked too early or too late [1].
This issue has been amplified by commit
d6fb6ee1820c ("ACPI: bus: Drop
driver member of struct acpi_device") that made acpi_bus_notify() check
for the presence of the driver and its ->notify() callback directly
instead of using an extra driver pointer that was only set and cleared
by the bus type code, but it was present before that commit although
it was harder to reproduce then.
It can be addressed by using the observation that
acpi_device_install_notify_handler() can be modified to install the
handler for all types of events when ACPI_DRIVER_ALL_NOTIFY_EVENTS is
set in the driver flags, in which case acpi_bus_notify() will not need
to invoke the driver's ->notify() callback any more and that callback
will only be invoked after acpi_device_install_notify_handler() has run
and before acpi_device_remove_notify_handler() runs, which implies the
correct ordering with respect to the other ACPI driver callbacks.
Modify the code accordingly and while at it, drop two redundant local
variables from acpi_bus_notify() and turn its description comment into
a proper kerneldoc one.
