The variations we have so far were intended to showcase the Rust
support in several major architectures, rather than cover everything.
But as long as LLVM (& the kernel, i.e. ClangBuiltLinux) supports the
target (and as long there are no compiler/toolchain issues), you
should be able to try it.

Mostly -- there is also `rust/kernel/c_types.rs` and you may need to
tweak `rust/compiler_builtins.rs`, but not much more.

Note that for the target spec files, the short-term plan is to
generate dynamically the target spec file according to what the
architecture requests, instead of using these static files. Longer
term, we need a Rust-stable way to setup custom targets from upstream
`rustc` (though it is not clear yet how it will look, e.g. it could be
via command-line flags).

Cheers,
Miguel

Rust support

This is the patch series (v4) to add support for Rust as a second
language to the Linux kernel.

If you are interested in following this effort, please join us in
the mailing list at:

    rust-for-linux@vger.kernel.org

and take a look at the project itself at:

    https://github.com/Rust-for-Linux

As usual, special thanks go to ISRG (Internet Security Research
Group) and Google for their financial support on this endeavor.

Cheers,
Miguel

# Rust support

This cover letter explains the major changes and updates done since
the previous ones. For those, please see:

    RFC: https://lore.kernel.org/lkml/20210414184604.23473-1-ojeda@kernel.org/
    v1:  https://lore.kernel.org/lkml/20210704202756.29107-1-ojeda@kernel.org/
    v2:  https://lore.kernel.org/lkml/20211206140313.5653-1-ojeda@kernel.org/
    v3:  https://lore.kernel.org/lkml/20220117053349.6804-1-ojeda@kernel.org/


## Infrastructure updates

There have been several improvements to the overall Rust support:

  - The Intel 0DAY/LKP kernel test robot is setting up Rust in their
    CI -- we already got the first reports from the bot which we
    could act upon, very useful!

  - KernelCI is also looking forward to enabling Rust in their runs.

  - The GitHub CI we use for quick pre-merge testing has been moved
    to use containers.

  - Kernel modules do not need to write the crate attributes
    `#![no_std]` and `#![feature(...)]` anymore, removing boilerplate.

  - Added single target support, including `.o`, `.s`, `.ll` and `.i`
    (i.e. macro expanded, similar to C preprocessed sources).

  - Explanation of the `helpers.c` file and licensing for helpers
    and exports.

  - The documentation logo is now vector based (SVG). In addition,
    a vector version of Tux has been proposed for upstream, and an
    RFC for improved custom logo support has been submitted to
    upstream Rust.

  - Added coding guidelines on comments (`//`) and code documentation
    (`///`).

  - `is_rust_module.sh` rework.

  - Generation of `.rmeta` for leaf modules is skipped now.

  - Other cleanups, fixes and improvements.


## Abstractions and driver updates

Some of the improvements to the abstractions and example drivers are:

  - Added support for static (global shared variables) synchronization
    primitives. `CONFIG_CONSTRUCTORS` are used for the implementation.

  - Simplification of the lock guards by using marker types, i.e.
    `Guard` and `GuardMut` are unified into a single parametrized
    type. If the marker is `WriteLock`, then `Guard` implements
    `DerefMut` (only implemented by `GuardMut` previously).

  - Optional parameters added to the registration of misc devices,
    following the builder pattern., e.g.

        miscdev::Options::new()
            .mode(0o600)
            .minor(10)
            .parent(parent)
            .register(reg, c_str!("sample"), ())

  - Added `RwSemaphore` abstraction that wraps the C side
    `struct rw_semaphore`.

  - New `mm` module and VMA abstraction (wrapping the C side
    `struct vm_area_struct`) for use with `mmap`.

  - GPIO PL061 now uses the recently added `dev_*!` Rust macros.

  - Support the `!CONFIG_PRINTK` case.

  - Other cleanups, fixes and improvements.


## Patch series status

The Rust support is still to be considered experimental. However,
support is good enough that kernel developers can start working on the
Rust abstractions for subsystems and write drivers and other modules.

The current series has just arrived in `linux-next`, as usual.
Similarly, the preview docs for this series can be seen at:

    https://rust-for-linux.github.io/docs/kernel/

As usual, please see the following link for the
live list of unstable Rust features we are using:

## Acknowledgements

The signatures in the main commits correspond to the people that
wrote code that has ended up in them at the present time. For details
on contributions to code and discussions, please see our repository:

    https://github.com/Rust-for-Linux/linux

However, we would like to give credit to everyone that has contributed
in one way or another to the Rust for Linux project. Since the
previous cover letter:

  - Philip Li, Yujie Liu et. al. for setting the Intel 0DAY/LKP kernel
    test robot with Rust support.

  - Garrett LeSage and IFo Hancroft for agreeing to the usage of
    their vector version of Tux within the kernel tree with the same
    license as the existing one from Larry Ewing.

  - Nathan Chancellor for noticing a case where a C module was being
    identified as a Rust one for purposes of skipping BTF generation
    and suggesting a few improvements around `is_rust_module.sh`.

  - Wei Liu for exporting the remaining helpers and triggering a
    useful discussion around it.

  - Miguel Cano for fixing an issue with compilers containing a full,
    3-part version in the suffix part (e.g. Ubuntu Clang).

    `# Safety` sections to the code generated by the `module!` macro.

  - Jiapeng Chong and the Abaci Robot for reporting and fixing
    an unneeded header `#include`.

  - Finn Behrens for resuming his work on building Rust for Linux
    on Nix and spotting and fixing usability issues.

  - As usual, Gary Guo and bjorn3 for all the input on Rust compiler
    details and all the reviews and suggestions.

  - John Ericson, TennyZhuang and Xuanwo for their ongoing work on
    adding more fallible allocation methods (`try_*`) to the Rust
    standard library.

* [PATCH v4 16/20] Kbuild: add Rust support
From: Miguel Ojeda @ 2022-02-12 13:03 UTC (permalink / raw)

In-Reply-To: <20220212130410.6901-1-ojeda@kernel.org>

Having all the new files in place, we now enable Rust support
in the build system, including `Kconfig` entries related to Rust,
the Rust configuration printer, the target definition files,
the version detection script and a few other bits.

In the future, we will likely want to generate the target files
on the fly via a script.

+# This prepares a custom sysroot with our custom `alloc` instead of
+# the standard one.
+#
+# This requires several hacks:
+#   - Unlike `core` and `alloc`, `std` depends on more than a dozen crates,
+#     including third-party crates that need to be downloaded, plus custom
+#     `build.rs` steps. Thus hardcoding things here is not maintainable.
+#   - `cargo` knows how to build the standard library, but it is an unstable
+#     feature so far (`-Zbuild-std`).
+#   - `cargo` only considers the use case of building the standard library
+#     to use it in a given package. Thus we need to create a dummy package
+#     and pick the generated libraries from there.
+#   - Since we only keep a subset of upstream `alloc` in-tree, we need
+#     to recreate it on the fly by putting our sources on top.
+#   - The usual ways of modifying the dependency graph in `cargo` do not seem
+#     to apply for the `-Zbuild-std` steps, thus we have to mislead it
+#     by modifying the sources in the sysroot.
+#   - To avoid messing with the user's Rust installation, we create a clone
+#     of the sysroot. However, `cargo` ignores `RUSTFLAGS` in the `-Zbuild-std`
+#     steps, thus we use a wrapper binary passed via `RUSTC` to pass the flag.
+#
+# In the future, we hope to avoid the whole ordeal by either:
+#   - Making the `test` crate not depend on `std` (either improving upstream
+#     or having our own custom crate).
+#   - Making the tests run in kernel space (requires the previous point).
+#   - Making `std` and friends be more like a "normal" crate, so that

Dear Linux folks,


Running rcutorture on the POWER8 system IBM S822LC with Ubuntu 20.10, it 
found the bug below. I more or less used rcu/dev (0ba8896d2fd7 
(lib/irq_poll: Declare IRQ_POLL softirq vector as ksoftirqd-parking 
safe)) [1]. The bug manifested for the four configurations below.

1.  results-rcutorture-kasan/SRCU-T
2.  results-rcutorture-kasan/TINY02
3.  results-rcutorture/SRCU-T
4.  results-rcutorture/TINY02

For example, the attached

 
/dev/shm/linux/tools/testing/selftests/rcutorture/res/2022.02.11-22.00.51-torture/results-rcutorture-kasan/SRCU-T/console.log

contains:

d338d22b9d338 tick/rcu: Remove obsolete rcu_needs_cpu() parameters

Though it might be that these are victims of circumstance, in other
words, that the original bug that Paul Menzel reported was caused by
something else.

That is ppc64.
What happens on x86-64?

Trying to do the same in the x86 ipcsum code tended to make the code worse.
(Although that test is for an odd length fragment and can just be removed.)

They are not always equivalent.
In particular in the UDP checksum field one of them is (0?) 'checksum not calculated'.

I think all the Linux functions have to return a non-zero value (for non-zero input).

If the csum is going to be converted to 16 bit, inverted, and put into a packet
the code usually has to have a check that changes 0 to 0xffff.
However if the csum functions guarantee never to return zero they can feed
an extra 1 into the first csum_partial() then just invert and add 1 at the end.
Because (~csum_partion(buffer, 1) + 1) is the same as ~csum_partial(buffer, 0)
except when the buffer's csum is 0xffffffff.

I did do some experiments and the 64bit value can be reduced directly to
16bits using '% 0xffff'.
This is different because it returns 0 not 0xffff.
However gcc 'randomly' picks between the fast 'multiply by reciprocal'
and slow divide instruction paths.
The former is (probably) faster than reducing using shifts and adc.
The latter definitely slower.

Dear Paul

I think the key to the problem lies in your attached console.log
(pasted below), at times 0.014987 and 0.015995, I see there are two
locks (cpu_hotplug_lock and jump_label_mutex)  holded while
kmem_cache_alloc calls __might_resched (0.023356).

I guess PowerPC's map_patch_area should  temporary release above two
locks before invoking map_kernel_page (which will call
kmem_cache_alloc):

static int map_patch_area(void *addr, unsigned long text_poke_addr)
{
        unsigned long pfn;
        int err;

        if (is_vmalloc_or_module_addr(addr))
                pfn = vmalloc_to_pfn(addr);
        else
                pfn = __pa_symbol(addr) >> PAGE_SHIFT;

        err = map_kernel_page(text_poke_addr, (pfn << PAGE_SHIFT), PAGE_KERNEL);

        pr_devel("Mapped addr %lx with pfn %lx:%d\n", text_poke_addr, pfn, err);
        if (err)
                return -1;

        return 0;
}

I will try to think it over in the coming days.

Those are both sleeping locks (a percpu_rwsem and mutex, respectively).
There is no problem with sleeping while holding a mutex or rwsem.

From console.log, I see
[    0.012154][    T1] BUG: sleeping function called from invalid
context at include/linux/sched/mm.h:256
[    0.013128][    T1] in_atomic(): 0, irqs_disabled(): 1, non_block:
0, pid: 1, name: swapper/0
From ___might_sleep, I see

9506         if ((preempt_count_equals(preempt_offset) && !irqs_disabled() &&
9507              !is_idle_task(current) && !current->non_block_count) ||
9508             system_state == SYSTEM_BOOTING || system_state >
SYSTEM_RUNNING ||
9509             oops_in_progress)
9510                 return;

I guess it is irq_disable which cause the bug.

Thanks

Even without these three patches, the issue is reproducible. I tested 
commit 7a935b7ac61b (tools/nolibc/stdlib: implement abort()).


Kind regards,

* [PATCH] powerpc: Don't allow the use of EMIT_BUG_ENTRY with BUGFLAG_WARNING
From: Christophe Leroy @ 2022-02-13  9:02 UTC (permalink / raw)
  To: Benjamin Herrenschmidt, Paul Mackerras, Michael Ellerman
  Cc: linuxppc-dev, linux-kernel

Warnings in assembly must use EMIT_WARN_ENTRY in order to generate
the necessary entry in exception table.

Check in EMIT_BUG_ENTRY that flags don't include BUGFLAG_WARNING.

This change avoids problems like the one fixed by
commit fd1eaaaaa686 ("powerpc/64s: Use EMIT_WARN_ENTRY for SRR debug
warnings").

That is 32-bit powerpc.

In an ideal world the compiler could choose the optimal code sequences
everywhere.  But that won't ever happen, the search space is way too
big.  So compilers just use heuristics, not exhaustive search like
superopt does.  There is a middle way of course, something with directed
searches, and maybe in a few decades systems will be fast enough.  Until
then we will very often see code that is 10% slower and 30% bigger than
necessary.  A single insn more than needed isn't so bad :-)

Making things branch-free is very much worth it here though!

Ah, I thought you were saying that the issue was caused by them.

I will put them back.  And apologies to Frederic for kicking his
patches out!

Are you able to bisect to see what commit introduced the problem?

Hi Ahmad-san,

Thanks for your confirmations. Sorry for late to reply.

Could you please try the patch attached to disable the chip_good() 
change as before?
I think this should work for S29GL964N since the chip_ready() is used 
and works as mentioned.

I see and check the data sheet as described.

Sorry I am not sure about this.
I thought the chip_ready() itself is correct as implemented as the data 
sheet in the past.
But it did not work correctly so changed to use chip_good() instead as 
it is also correct.

The change attached checks the device ID 0x0c01 and use chip_ready() 
instead on chip_good().

Sorry my understanding was not correct about the data sheet description 
device ID and cycle.

Subject: [PATCH] mtd: cfi_cmdset_0002: Use chip_ready() for write on S29GL064N

The regression issue has been caused on S29GL064N and reported it.
Also the change mentioned is to use chip_good() for buffered write.
So disable the change on S29GL064N and use chip_ready() as before.

Sorry for being unclear.

I have not checked yet, if it’s a regression. I am going to test it next 
week.

I tried to find out where 'here' is.

I can't get godbolt to generate anything like that object code
for a call to csum_shift().

I can't actually get it to issue a rotate (x86 of ppc).

I think it is only a single instruction because the compiler
has saved 'offset & 1' much earlier instead of doing testing
'offset & 1' just prior to the conditional.
It certainly has a nasty habit of doing that pessimisation.

So while it helps a specific call site it may be much
worse in general.

I also suspect that the addc/addze pair could be removed
by passing the old checksum into csum_partial.

FYI, a soft boot doesn't clear the TPM PCRs.  To be able to verify the
IMA measurement list after a kexec against a TPM quote, requires
carrying the measurement list across kexec.

The "IMA_KEXEC" config enables carrying the IMA measurement list across
kexec.  It has nothing to do with verifying the appended signature. 
That is based on kernel module appended signature code.

Measuring the kexec kernel image and extending the TPM with the
measurement is required for trusted boot.  Boot loaders extend the
TPM's BIOS measurements. Similarly, IMA does not require a TPM, but if
one is available the kexec kernel image measurement is extended into
the IMA measurement list.  Otherwise, IMA goes into "TPM by-pass" mode.

True.  However, a kernel image with an appended signature may be
kexec'ed, regardless of the architecture.  Because some boot loaders
don't support appended signatures, from my point of view does not make
IMA kexec support not portable.

This Kconfig carries the IMA measurement list across kexec.  This has
nothing to do with appended signatures.

config IMA_KEXEC
        bool "Enable carrying the IMA measurement list across a soft
boot"
        depends on IMA && TCG_TPM && HAVE_IMA_KEXEC

In addition to powerpc, arm64 sets HAVE_IMA_KEXEC.

Even prior to the kexec appended signature support, like all other
files, the kexec kernel image signature could be stored in
security.ima.

The kexec kernel image measurement will not be included in the BIOS
event log.  Even if the measurement is included in the IMA measurement
list, without the IMA_KEXEC Kconfig the measurement list will not be
carried across kexec.  For those not interested in "trusted boot" or
those who do not need it for compliance, the simplification should be
fine.

tools/testing/selftests/kexec/test_kexec_file_load.sh probably needs to
be updated to reflect the new Kconfig support.

FYI, commit 65e38e32a959 ("selftests/kexec: Enable secureboot tests for
PowerPC") recently was upstreamed.

Sounds good to me! Since a lot of the architecture is the same as the 
Wii and GameCube, maybe once things are working well for Wii U we can 
look at refactoring those out too - a "nintendo" platform? Not a concern 
for now though.

 From the devicetree:

memory {
     device_type = "memory";
     reg = <0x00000000 0x02000000        /* MEM1 - 32MiB */
            0x08000000 0x00300000        /* MEM0 - 3MiB  */
            0x10000000 0x80000000>;      /* MEM2 - 2GiB  */
};

We could probably drop MEM0 without anybody missing it, so let's say a 
256MiB gap between MEM1 and MEM2.
sparsemem does look like a good option, though I note it depends on 
ppc64, so yeah, might be a lot of trouble for the benefit of two 
platforms (Wii and Wii U).
I'm currently attempting to get something baseline running on 5.15, will 
see if the memblock thing still works so I can have a patch for RFC.

Maybe? Looking through head_book3s_32.S that appears to be the case. 
Will probably stick with physaddr 0 for now then.

No problem, will make sure everything is signed off by the people involved.

Emmanuel told me about this during their work on 5.13 which I wasn't 
involved in, and now can't remember any of the details, so I guess I 
don't actually have any more information.
I'm working on getting a baseline setup for 5.15 (just udbg and the 
like), so if there is an issue I should soon find out about it and will 
get back to you.

But not in this series? This is just to save you having to do more
renaming later?
