netdev_alloc_skb can fail and return a NULL pointer which is
dereferenced without a check. The patch avoids such a scenario.

When sending non-linear skbs with jumbo frames, we set up the non-paged
data and mark that as a last segment, although the paged fragments are
also prepared. This will stall the TX queue and trigger a watchdog warning
(a simple reproducer is to run an iperf client mode TCP test with a large
MTU - networking fails instantly).
Fix by checking if the skb is non-linear.

Commit 0e80bdc9a7 ("stmmac: first frame prep at the end of xmit
routine") overlooked jumbo frames when re-ordering the code, and as a
result the own bit was not getting set anymore for the first jumbo frame
descriptor. Commit 487e2e22ab ("net: stmmac: Set OWN bit for jumbo
frames") tried to fix this, but now the bit is getting set too early and
the DMA may start while we are still setting up the remaining descriptors.
And with the chain mode the own bit remains still unset.
Fix by setting the own bit at the end of xmit also with jumbo frames.

register_snap_client may return NULL, all the callers
check it, but only print a warning. This will result in
NULL pointer dereference in unregister_snap_client and other
places.
It has always been used like this since v2.6

Merge misc patches from Andrew Morton:
- a little bit more MM
- a few fixups
[ The "little bit more MM" is actually just one of the three patches
Andrew sent for mm/filemap.c, I'm still mulling over two more of them
from Josef Bacik - Linus ]
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
include/linux/swap.h: use offsetof() instead of custom __swapoffset macro
tools/testing/selftests/proc/proc-pid-vm.c: test with vsyscall in mind
zram: default to lzo-rle instead of lzo
filemap: pass vm_fault to the mmap ra helpers
Use offsetof() to calculate offset of a field to take advantage of
compiler built-in version when possible, and avoid UBSAN warning when
compiling with Clang:
UBSAN: Undefined behaviour in mm/swapfile.c:3010:38

updates this time around. It's the usual pile of new drivers for new
hardware out there and the normal small fixes and updates, but then we
have some core framework changes too.
In the core framework, we introduce support for a clk_get_optional() API
to get clks that may not always be populated and a way to devm manage clkdev
lookups registered by provider drivers. We also do some refactoring to simplify
the interface between clkdev and the common clk framework so we can reuse the DT
parsing and clk_get() path in provider drivers in the future. This work will
continue in the next few cycles while we convert how providers specify clk
parents.
On the driver side, the biggest part of the dirstat is the Amlogic clk driver
that got support for the G12A SoC. It dominates with almost half the overall
diff, while the second largest part of the diff is in the i.MX clk driver
that gained support for imx8mm SoCs. After that, we have the Actions Semiconductor
and Qualcomm drivers rounding out the big part of the dirstat because they both
got new hardware support for SoCs. The rest is just various updates and non-critical
fixes for existing drivers.
Core:
- Convert a few clk bindings to JSON schema format
- Add a {devm_}clk_get_optional() API
- Add devm_clk_hw_register_clkdev() API to manage clkdev lookups
- Start rewriting clk parent registration and supporting device links
by moving around code that supports clk_get() and DT parsing of the
'clocks' property
New Drivers:
- Add Qualcomm MSM8998 RPM managed clks
- IPA clk support on Qualcomm RPMh clk controllers
- Actions Semi S500 SoC clk support
- Support for fixed rate clks populated from an MMIO register

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk subsystem updates from Stephen Boyd:
"We have a fairly balanced mix of clk driver updates and clk framework
updates this time around. It's the usual pile of new drivers for new
hardware out there and the normal small fixes and updates, but then we
have some core framework changes too.
In the core framework, we introduce support for a clk_get_optional()
API to get clks that may not always be populated and a way to devm
manage clkdev lookups registered by provider drivers. We also do some
refactoring to simplify the interface between clkdev and the common
clk framework so we can reuse the DT parsing and clk_get() path in
provider drivers in the future. This work will continue in the next
few cycles while we convert how providers specify clk parents.
On the driver side, the biggest part of the dirstat is the Amlogic clk
driver that got support for the G12A SoC. It dominates with almost
half the overall diff, while the second largest part of the diff is in
the i.MX clk driver that gained support for imx8mm SoCs. After that,
we have the Actions Semiconductor and Qualcomm drivers rounding out
the big part of the dirstat because they both got new hardware support
for SoCs. The rest is just various updates and non-critical fixes for
existing drivers.
Core:
- Convert a few clk bindings to JSON schema format
- Add a {devm_}clk_get_optional() API
- Add devm_clk_hw_register_clkdev() API to manage clkdev lookups
- Start rewriting clk parent registration and supporting device links
by moving around code that supports clk_get() and DT parsing of the
'clocks' property
New Drivers:
- Add Qualcomm MSM8998 RPM managed clks
- IPA clk support on Qualcomm RPMh clk controllers
- Actions Semi S500 SoC clk support
- Support for fixed rate clks populated from an MMIO register
- Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H
- Add TMU (timer) clocks on Renesas RZ/G2E
- Add Amlogic G12A Always-On Clock Controller
- Add 32k clock generation for Amlogic AXG
- Add support for the Mali GPU clocks on Amlogic Meson8
- Add Amlogic G12A EE clock controller driver
- Add missing CANFD clocks on Renesas RZ/G2M and RZ/G2E

sk_setup_caps() is called to set sk->sk_dst_cache in pptp_connect,
so we have to dst_release(sk->sk_dst_cache) in pptp_sock_destruct,
otherwise, the dst refcnt will leak.
It can be reproduced by this syz log:
r1 = socket$pptp(0x18, 0x1, 0x2)
bind$pptp(r1, &(0x7f0000000100)={0x18, 0x2, {0x0, @local}}, 0x1e)
connect$pptp(r1, &(0x7f0000000000)={0x18, 0x2, {0x3, @remote}}, 0x1e)
Consecutive dmesg warnings will occur:

A previous fix ("tls: Fix write space handling") assumed that
user space application gets informed about the socket send buffer
availability when tls_push_sg() gets called. Inside tls_push_sg(), in
case do_tcp_sendpages() returns 0, the function returns without calling
ctx->sk_write_space. Further, the new function tls_sw_write_space()
did not invoke ctx->sk_write_space. This leads to situation that user
space application encounters a lockup always waiting for socket send
buffer to become available.
Rather than call ctx->sk_write_space from tls_push_sg(), it should be
called from tls_write_space. So whenever tcp stack invokes
sk->sk_write_space after freeing socket send buffer, we always declare
the same to user space by the way of invoking ctx->sk_write_space.

It is confusing to directly use return value of netlink_send()/
netlink_unicast() as the return value of *notify*, as it may be not
error at all.
Example: in tc_del_tfilter(), after calling tfilter_del_notify(), it will
goto errout if (err). However, the netlink_send()/netlink_unicast() will
return positive value even for successful case. So it may not call
tcf_chain_tp_remove() and so on to clean up the resource, as a result,
resource is leaked.
It may be easier to only check the return value of tfilter_del_nofiy(),
but it is more clean to correct all related functions.

It has been observed that tx queue may stall while downloading
from certain web sites (example www.speedtest.net)
The cause has been tracked down to a corner case where
the tx interrupt vector was disabled automatically, but
was not re enabled later.
The lan743x has two mechanisms to enable/disable individual
interrupts. Interrupts can be enabled/disabled by individual
source, and they can also be enabled/disabled by individual
vector which has been mapped to the source. Both must be
enabled for interrupts to work properly.
The TX code path, primarily uses the interrupt enable/disable of
the TX source bit, while leaving the vector enabled all the time.
However, while investigating this issue it was noticed that
the driver requested the use of the vector auto clear feature.
The test above revealed a case where the vector enable was
cleared unintentionally.
This patch fixes the issue by deleting the lines that request
the vector auto clear feature to be used.

Calculation of qp mtt size (in function mlx4_RST2INIT_wrapper)
ultimately depends on function roundup_pow_of_two.
If the amount of memory required by the QP is less than one page,
roundup_pow_of_two is called with argument zero. In this case, the
roundup_pow_of_two result is undefined.
Calling roundup_pow_of_two with a zero argument resulted in the
following stack trace:

In procedures mlx4_cmd_use_events() and mlx4_cmd_use_polling(), we need to
guarantee that there are no FW commands in progress on the comm channel
(for VFs) or wrapped FW commands (on the PF) when SRIOV is active.
We do this by also taking the slave_cmd_mutex when SRIOV is active.
This is especially important when switching from event to polling, since we
free the command-context array during the switch. If there are FW commands
in progress (e.g., waiting for a completion event), the completion event
handler will access freed memory.
Since the decision to use comm_wait or comm_poll is taken before grabbing
the event_sem/poll_sem in mlx4_comm_cmd_wait/poll, we must take the
slave_cmd_mutex as well (to guarantee that the decision to use events or
polling and the call to the appropriate cmd function are atomic).

As part of unloading a device, the driver switches from
FW command event mode to FW command polling mode.
Part of switching over to polling mode is freeing the command context array
memory (unfortunately, currently, without NULLing the command context array
pointer).
The reset flow calls "complete" to complete all outstanding fw commands
(if we are in event mode). The check for event vs. polling mode here
is to test if the command context array pointer is NULL.
If the reset flow is activated after the switch to polling mode, it will
attempt (incorrectly) to complete all the commands in the context array --
because the pointer was not NULLed when the driver switched over to polling
mode.
As a result, we have a use-after-free situation, which results in a
kernel crash.

mlxsw: Various fixes
Patch #1 fixes the recently introduced QSFP thermal zones to correctly
work with split ports, where several ports are mapped to the same
module.
Patch #2 initializes the base MAC in the minimal driver. The driver is
using the base MAC as its parent ID and without initializing it, it is
reported as all zeroes to user space.

Verify during thermal initialization if QSFP module's entry is already
configured in order to prevent duplication.
Such scenario could happen in case two switch drivers (PCI and I2C
based) coexist and if after boot, splitting configuration is applied
for some ports and then I2C based driver is re-probed.
In such case after reboot same QSFP module, associated with split will
be discovered by I2C based driver few times, and it will cause a crash.
It could happen for example on system equipped with BMC (Baseboard
Management Controller), running I2C based driver, when the next steps
are performed:
- System boot
- Host side configures port spilt.
- BMC side is rebooted.
