Some architectures like arm64 and s390 require USER_DS to be set for
kernel threads to access user address space, which is the whole purpose of
kthread_use_mm, but other like x86 don't. That has lead to a huge mess
where some callers are fixed up once they are tested on said
architectures, while others linger around and yet other like io_uring try
to do "clever" optimizations for what usually is just a trivial asignment
to a member in the thread_struct for most architectures.
Make kthread_use_mm set USER_DS, and kthread_unuse_mm restore to the
previous value instead.

Switch the function documentation to kerneldoc comments, and add
WARN_ON_ONCE asserts that the calling thread is a kernel thread and does
not have ->mm set (or has ->mm set in the case of unuse_mm).
Also give the functions a kthread_ prefix to better document the use case.

Patch series "improve use_mm / unuse_mm", v2.
This series improves the use_mm / unuse_mm interface by better documenting
the assumptions, and my taking the set_fs manipulations spread over the
callers into the core API.
This patch (of 3):
Use the proper API instead.
Link: http://lkml.kernel.org/r/[email protected]
These helpers are only for use with kernel threads, and I will tie them
more into the kthread infrastructure going forward. Also move the
prototypes to kthread.h - mmu_context.h was a little weird to start with
as it otherwise contains very low-level MM bits.

Modify the variable type of 'skip' member of struct stack_trace.
In theory, the 'skip' variable type should be unsigned int.
There are two reasons:
- The 'skip' only has two situation, 1)Positive value, 2)Zero
- The 'skip' of struct stack_trace has inconsistent type with struct
stack_trace_data, it makes a bit confusion in the relationship between
struct stack_trace and stack_trace_data.

While making other modifications it was easy to confuse the two struct
members node_zones and node_zonelists. For those already familiar with
the code, this might seem to be a silly patch, but it's quite helpful to
disambiguate the similar-sounding fields
While here, add a small comment on why nr_zones isn't simply MAX_NR_ZONES

After commit c3aab9a0bd91 ("mm/filemap.c: don't initiate writeback if

This crash turned out to be caused by set_page_writeback() call for
segment summary buffers at nilfs_segctor_prepare_write().
set_page_writeback() can call inc_wb_stat(inode_to_wb(inode),
WB_WRITEBACK) where inode_to_wb(inode) is NULL if the inode of
underlying block device does not have an associated wb.
This fixes the issue by calling inode_attach_wb() in advance to ensure
to associate the bdev inode with its wb.

kcov_remote_stop() should check that the corresponding kcov_remote_start()
actually found the specified remote handle and started collecting
coverage. This is done by checking the per thread kcov_softirq flag.
A particular failure scenario where this was observed involved a softirq
with a remote coverage collection section coming between check_kcov_mode()
and the access to t->kcov_area in __sanitizer_cov_trace_pc(). In that
softirq kcov_remote_start() bailed out after kcov_remote_find() check, but
the matching kcov_remote_stop() didn't check if kcov_remote_start()
succeeded, and overwrote per thread kcov parameters with invalid (zero)
values.

If a listening MPTCP socket has unaccepted sockets at close
time, the related msks are freed via mptcp_sock_destruct(),
which in turn does not invoke the proto->destroy() method
nor the mptcp_token_destroy() function.
Due to the above, the child msk socket is not removed from
the token container, leading to later UaF.
Address the issue explicitly removing the token even in the
above error path.

depend on very complex macros with 'sizeof' or __builtin_choose_expr()

The msk sk_shutdown flag is set by a workqueue, possibly
introducing some delay in user-space notification. If the last
subflow carries some data with the fin packet, the user space
can wake-up before RCV_SHUTDOWN is set. If it executes unblocking
recvmsg(), it may return with an error instead of eof.
Address the issue explicitly checking for eof in recvmsg(), when
no data is found.

fdb nexthops are marked with a flag. For standalone nexthops, a flag was
added to the nh_info struct. For groups that flag was added to struct
nexthop when it should have been added to the group information. Fix
by removing the flag from the nexthop struct and adding a flag to nh_group
that mirrors nh_info and is really only a caching of the individual types.
Add a helper, nexthop_is_fdb, for use by the vxlan code and fixup the
internal code to use the flag from either nh_info or nh_group.

Pull clk updates from Stephen Boyd:
"This time around we have four lines of diff in the core framework,
removing a function that isn't used anymore. Otherwise the main new
thing for the common clk framework is that it is selectable in the
Kconfig language now. Hopefully this will let clk drivers and clk
consumers be testable on more than the architectures that support the
clk framework. The goal is to introduce some Kunit tests for the
framework.
Outside of the core framework we have the usual set of various driver
updates and non-critical fixes. The dirstat shows that the new
Baikal-T1 driver is the largest addition this time around in terms of
lines of code. After that the x86 (Intel), Qualcomm, and Mediatek
drivers introduce many lines to support new or upcoming SoCs. After
that the dirstat shows the usual suspects working on their SoC support
by fixing minor bugs, correcting data and converting some of their DT
bindings to YAML.
Core:
- Allow the COMMON_CLK config to be selectable
New Drivers:
- Clk driver for Baikal-T1 SoCs
- Mediatek MT6765 clock support
- Support for Intel Agilex clks
- Add support for X1830 and X1000 Ingenic SoC clk controllers
- Add support for the new Renesas RZ/G1H (R8A7742) SoC
- Add support for Qualcomm's MSM8939 Generic Clock Controller
Updates:
- Support IDT VersaClock 5P49V5925
- Bunch of updates for HSDK clock generation unit (CGU) driver
- Start making audio and GPU clks work on Marvell MMP2/MMP3 SoCs
- Add some GPU, NPU, and UFS clks to Qualcomm SM8150 driver
- Enable supply regulators for GPU gdscs on Qualcomm SoCs
- Add support for Si5342, Si5344 and Si5345 chips
- Support custom flags in Xilinx zynq firmware
- Various small fixes to the Xilinx clk driver
- A single minor rounding fix for the legacy Allwinner clock support
- A few patches from Abel Vesa as preparation of adding audiomix
clock support on i.MX
- A couple of cleanups from Anson Huang for i.MX clk-sscg-pll and
clk-pllv3 drivers
- Drop dependency on ARM64 for i.MX8M clock driver, to support
aarch32 mode on aarch64 hardware
- A series from Peng Fan to improve i.MX8M clock drivers, using
composite clock for core and bus clk slice
- Set a better parent clock for flexcan on i.MX6UL to support CiA102
defined bit rates
- A couple changes for EMC frequency scaling on Tegra210
- Support for CPU frequency scaling on Tegra20/Tegra30
- New clk gate for CSI test pattern generator on Tegra210
- Regression fixes for Samsung exynos542x and exynos5433 SoCs
- Use of fallthrough; attribute for Samsung s3c24xx
- Updates and fixup HDMI and video clocks on Meson8b
- Fixup reset polarity on Meson8b
- Fix GPU glitch free mux switch on Meson gx and g12
- A minor fix for the currently unused suspend/resume handling on
Renesas RZ/A1 and RZ/A2
- Two more conversions of Renesas DT bindings to json-schema
- Add support for the USB 2.0 clock selector on Renesas R-Car M3-W+"
