The RISC-V port has grown significantly over the past year. Paul's been
helping out for a while ago. We agreed in person that he'd take over
collecting the patches and submitting the PRs, but it looks like I
forgot to make it official.

Enable the sys_clone3 syscall for RV64. We simply include the generic

Tested by running the program from

the unnecessary DMZ_ACTIVE state.
- A couple fixes for issues the DM snapshot target's optional discard
support added during first week of the 5.3 merge.
- Increase default size of outstanding IO that is allowed for a each
dm-kcopyd client and introduce tunable to allow user adjust.
- Update DM core to use printk ratelimiting functions rather than
duplicate them and in doing so fix an issue where DMDEBUG_LIMIT() rate
limited KERN_DEBUG messages had excessive "callbacks suppressed"
messages.

- Fix zone state management race in DM zoned target by eliminating the
unnecessary DMZ_ACTIVE state.

support added during first week of the 5.3 merge.
- Increase default size of outstanding IO that is allowed for a each
dm-kcopyd client and introduce tunable to allow user adjust.

Merge floppy ioctl verification fixes from Denis Efremov.
This also marks the floppy driver as orphaned - it turns out that Jiri
no longer has working hardware.
Actual working physical floppy hardware is getting hard to find, and
while Willy was able to test this, I think the driver can be considered
pretty much dead from an actual hardware standpoint. The hardware that
is still sold seems to be mainly USB-based, which doesn't use this
legacy driver at all.
The old floppy disk controller is still emulated in various VM
environments, so the driver isn't going away, but let's see if anybody
is interested to step up to maintain it.
The lack of hardware also likely means that the ioctl range verification
fixes are probably mostly relevant to anybody using floppies in a
virtual environment. Which is probably also going away in favor of USB
storage emulation, but who knows.
Will Decon reviewed the patches but I'm not rebasing them just for that,
so I'll add a

I volunteered myself to maintain it quite some time ago back when I
fixed the concurrency issues which exhibited itself only with
VM-emulated devices, and at the same time I still had the physical 3.5"
reader to test all the changes.
The reader doesn't work any more though, so I guess it's time to step
down from this super-prestigious role :p and mark floppy.c as Orphaned.

Commit c296d4dc13 ("asm-generic: fix a compilation warning")
converted the various flush_*cache_* macros in
asm-generic/cacheflush.h to static inline functions. This breaks
RISC-V builds, since RISC-V's cacheflush.h includes the generic
cacheflush.h and then undefines the macros to be overridden.
Fix by copying the subset of the no-op functions that are reused from
the generic cacheflush.h into the RISC-V cacheflush.h, and dropping
the include of the generic cacheflush.h.

The FDDEFPRM ioctl allows one to set the geometry of a disk. The sect
and head fields (unsigned int) of the floppy_drive structure are used to
compute the max_sector (int) in the make_raw_rw_request function. It is
possible to overflow the max_sector. Next, max_sector is passed to the
copy_buffer function and used in one of the memcpy calls.
An unprivileged user could trigger the bug if the device is accessible,
but requires a floppy disk to be inserted.
The patch adds the check for the .sect * .head multiplication for not
overflowing in the set_geometry function.
The bug was found by syzkaller.

This fixes the invalid pointer dereference in the drive_name function of
the floppy driver.
The native_format field of the struct floppy_drive_params is used as
floppy_type array index in the drive_name function. Thus, the field
should be checked the same way as the autodetect field.
To trigger the bug, one could use a value out of range and set the drive
parameters with the FDSETDRVPRM ioctl. Next, FDGETDRVTYP ioctl should
be used to call the drive_name. A floppy disk is not required to be
inserted.
CAP_SYS_ADMIN is required to call FDSETDRVPRM.
The patch adds the check for a value of the native_format field to be in
the '0 <= x < ARRAY_SIZE(floppy_type)' range of the floppy_type array
indices.

This fixes a divide by zero error in the setup_format_params function of
the floppy driver.
Two consecutive ioctls can trigger the bug: The first one should set the
drive geometry with such .sect and .rate values for the F_SECT_PER_TRACK
to become zero. Next, the floppy format operation should be called.
A floppy disk is not required to be inserted. An unprivileged user
could trigger the bug if the device is accessible.
The patch checks F_SECT_PER_TRACK for a non-zero value in the
set_geometry function. The proper check should involve a reasonable
upper limit for the .sect and .rate fields, but it could change the
UAPI.
The patch also checks F_SECT_PER_TRACK in the setup_format_params, and
cancels the formatting operation in case of zero.

On parisc the privilege level of a process is stored in the lowest two bits of
the instruction pointers (IAOQ0 and IAOQ1). On Linux we use privilege level 0
for the kernel and privilege level 3 for user-space. So userspace should not be
allowed to modify IAOQ0 or IAOQ1 of a ptraced process to change it's privilege
level to e.g. 0 to try to gain kernel privileges.
This patch prevents such modifications in the regset support functions by
always setting the two lowest bits to one (which relates to privilege level 3
for user-space) if IAOQ0 or IAOQ1 are modified via ptrace regset calls.

side. The two main highlights in the core framework are the addition of an bulk
clk_get API that handles optional clks and an extra debugfs file that tells the
developer about the current parent of a clk.
The driver updates are dominated by i.MX in the diffstat, but that is mostly
because that SoC has started converting to the clk_hw style of clk
registration. The next big update is in the Amlogic meson clk driver that
gained some support for audio, cpu, and temperature clks while fixing some PLL
issues. Finally, the biggest thing that stands out is the conversion of a large
part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses
less strings and more pointer comparisons to match clk parents and children up.
In general, it looks like we have a lot of little fixes and tweaks here and
there to clk data along with the normal addition of a handful of new drivers
and a couple new core framework features.
Core:
- Add a 'clk_parent' file in clk debugfs
- Add a clk_bulk_get_optional() API (with devm too)
New Drivers:
- Support gated clk controller on MIPS based BCM63XX SoCs
- Support SiLabs Si5341 and Si5340 chips

Pull clk updates from Stephen Boyd:
"This round of clk driver and framework updates is heavy on the driver
update side. The two main highlights in the core framework are the
addition of an bulk clk_get API that handles optional clks and an
extra debugfs file that tells the developer about the current parent
of a clk.
The driver updates are dominated by i.MX in the diffstat, but that is
mostly because that SoC has started converting to the clk_hw style of
clk registration. The next big update is in the Amlogic meson clk
driver that gained some support for audio, cpu, and temperature clks
while fixing some PLL issues. Finally, the biggest thing that stands
out is the conversion of a large part of the Allwinner sunxi-ng driver
to the new clk parent scheme that uses less strings and more pointer
comparisons to match clk parents and children up.
In general, it looks like we have a lot of little fixes and tweaks
here and there to clk data along with the normal addition of a handful
of new drivers and a couple new core framework features.
Core:
- Add a 'clk_parent' file in clk debugfs
- Add a clk_bulk_get_optional() API (with devm too)
New Drivers:
- Support gated clk controller on MIPS based BCM63XX SoCs
- Support SiLabs Si5341 and Si5340 chips
- Support for CPU clks on Raspberry Pi devices
- Audsys clock driver for MediaTek MT8516 SoCs
