This series fixes the RCU stalls triggered by the x86 crypto
modules discussed in
https://lore.kernel.org/all/MW5PR84MB18426EBBA3303770A8BC0BDFAB759@MW5PR84MB1842.NAMPRD84.PROD.OUTLOOK.COM/
Two root causes were:
- too much data processed between kernel_fpu_begin and
kernel_fpu_end calls (which are heavily used by the x86
optimized drivers)
- tcrypt not calling cond_resched during speed test loops
These problems have always been lurking, but improving the
loading of the x86/sha512 module led to it happening a lot
during boot when using SHA-512 for module signature checking.
Fixing these problems makes it safer to improve loading
the rest of the x86 modules like the sha512 module.
This series only handles the x86 modules.
Testing
=======
The most effective testing was by enabling
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y
which creates random test vectors and compares the results
of the CPU-optimized function to the generic function,
and running two threads of repeated modprobe commands
to exercise those tests:
watch -n 0 modprobe tcrypt mode=200
watch -n 0 ./tcrypt_sweep
where tcrypt_sweep walks through all the test modes:
#!/usr/bin/perl
use strict;
my @modes;
open SOURCE, "<", "/home/me/linux/crypto/tcrypt.c" or die $!;
while (<SOURCE>) {
if (/^\s+case ([0-9]+):$/) {
push @modes, $1;
}
}
close SOURCE;
foreach (@modes) {
print "$_ ";
# don't run mode 300, which runs 301-399
# don't run mode 400, which runs 401-499
if (($_ eq "0") || ($_ eq "300") || ($_ eq "400")) {
system "echo \"===== Skipping special modprobe tcrypt mode=$_\" > /dev/kmsg";
} else {
system "echo \"Running modprobe tcrypt mode=$_\" > /dev/kmsg";
system "modprobe tcrypt mode=$_";
}
}

Fixing these problems makes it safer to improve loading the rest of the x86 modules like the sha512 module. This series only handles the x86 modules. Version 4 tackles lingering comments from version 2. 1. Unlike the hash functions, skcipher and aead functions accept pointers to scatter-gather lists, and the helper functions that walk through those lists limit processing to a page size at a time. The aegis module did everything inside one pair of kernel_fpu_begin() and kernel_fpu_end() calls including walking through the sglist, so it could preempt the CPU without constraint. The aesni aead functions for gcm process the additional data (data that is included in the authentication tag calculation but not encrypted) in one FPU context, so that can be a problem. This will require some asm changes to fix. However, I don't think that is a typical use case, so this series defers fixing that. The series adds device table matching for all the x86 crypto modules. 2. I replaced all the positive and negative prints with module parameters, including enough clues in modinfo descriptions that a user can determine what is working and not working.

Yes. With the v4 patch numbers:
[PATCH v4 01/24] crypto: tcrypt - test crc32
[PATCH v4 02/24] crypto: tcrypt - test nhpoly1305
Those ensure the changes to those hash modules are testable.
[PATCH v4 03/24] crypto: tcrypt - reschedule during cycles speed
That's only for tcrypt so not urgent for users, but pretty
simple.
[PATCH v4 04/24] crypto: x86/sha - limit FPU preemption
[PATCH v4 05/24] crypto: x86/crc - limit FPU preemption
[PATCH v4 06/24] crypto: x86/sm3 - limit FPU preemption
[PATCH v4 07/24] crypto: x86/ghash - use u8 rather than char
[PATCH v4 08/24] crypto: x86/ghash - restructure FPU context saving
[PATCH v4 09/24] crypto: x86/ghash - limit FPU preemption
[PATCH v4 10/24] crypto: x86/poly - limit FPU preemption
[PATCH v4 11/24] crypto: x86/aegis - limit FPU preemption
[PATCH v4 12/24] crypto: x86/sha - register all variations
[PATCH v4 13/24] crypto: x86/sha - minimize time in FPU context
That's the end of the fixes set.
[PATCH v4 14/24] crypto: x86/sha - load based on CPU features
[PATCH v4 15/24] crypto: x86/crc - load based on CPU features
[PATCH v4 16/24] crypto: x86/sm3 - load based on CPU features
[PATCH v4 17/24] crypto: x86/poly - load based on CPU features
[PATCH v4 18/24] crypto: x86/ghash - load based on CPU features
[PATCH v4 19/24] crypto: x86/aesni - avoid type conversions
[PATCH v4 20/24] crypto: x86/ciphers - load based on CPU features
[PATCH v4 21/24] crypto: x86 - report used CPU features via module
[PATCH v4 22/24] crypto: x86 - report missing CPU features via module
[PATCH v4 23/24] crypto: x86 - report suboptimal CPUs via module
[PATCH v4 24/24] crypto: x86 - standardize module descriptions
I'll put those in a new series.
For 6.1, I still suggest reverting aa031b8f702e ("crypto: x86/sha512 -
load based on CPU features) since that exposed the problem. Target
the fixes for 6.2 and module loading for 6.2 or 6.3.

2.38.1commit 2af632996b89 ("crypto: tcrypt - reschedule during speed tests")
added cond_resched() calls to "Avoid RCU stalls in the case of
non-preemptible kernel and lengthy speed tests by rescheduling when
advancing from one block size to another."
It only makes those calls if the sec module parameter is used
(run the speed test for a certain number of seconds), not the
default "cycles" mode.
Expand those to also run in "cycles" mode to reduce the rate
of rcu stall warnings:

2.38.1Limit the number of bytes processed between kernel_fpu_begin() and
kernel_fpu_end() calls.
Those functions call preempt_disable() and preempt_enable(), so
the CPU core is unavailable for scheduling while running.
This leads to "rcu_preempt detected expedited stalls" with stack dumps
pointing to the optimized hash function if the module is loaded and
used a lot:
rcu: INFO: rcu_preempt detected expedited stalls on CPUs/tasks: ...
For example, that can occur during boot with the stack track pointing
to the sha512-x86 function if the system set to use SHA-512 for
module signing. The call trace includes:
module_sig_check
mod_verify_sig
pkcs7_verify
pkcs7_digest
sha512_finup
sha512_base_do_update
Fixes: 66be89515888 ("crypto: sha1 - SSSE3 based SHA1 implementation for x86-64")
Fixes: 8275d1aa6422 ("crypto: sha256 - Create module providing optimized SHA256 routines using SSSE3, AVX or AVX2 instructions.")

v3 simplify to while loops rather than do..while loops, avoid
redundant checks for zero length, rename the limit macro and
change into a const, vary the limit for each algo

add algorithm-specific limits, use local stack variable in crc32 finup
rather than the context pointer like update uses

Use an enum for constants like this:
enum { BYTES_PER_FPU = ... };
You can even make it function-local, so it's near the code that uses it,
which will better justify its existence.
Also, where did you get this number? Seems kind of weird.

Does this add a needless additional check or does it generate better
code? Would be nice to have some explanation of the rationale.
Same comments as above apply for the rest of this patch ans series.

These numbers are highly dependent on hardware and I think having
them hard-coded is wrong.
Perhaps we should try a different approach. How about just limiting
the size to 4K, and then depending on need_resched we break out of
the loop? Something like:
if (!len)
return 0;
kernel_fpu_begin();
for (;;) {
unsigned int chunk = min(len, 4096);
sha1_base_do_update(desc, data, chunk, sha1_xform);
len -= chunk;
data += chunk;
if (!len)
break;
if (need_resched()) {
kernel_fpu_end();
cond_resched();
kernel_fpu_begin();
}
}
kernel_fpu_end();

I implemented that conditional approach in the sha algorithms.
The results of a boot (using sha512 for module signatures, with
crypto extra tests enabled, comparing to sha512 with a 20 KiB
fixed limit) are:
sha1 cond: 14479 calls; 784256 cycles doing begin/end; longest FPU context 35828 cycles
sha256 cond: 26763 calls; 1273570 cycles doing begin/end; longest FPU context 118612 cycles
sha512 cond: 26957 calls; 1680046 cycles doing begin/end; longest FPU context 169140982 cycles
sha512 20KiB: 161011 calls; 16232280 cycles doing begin/end; longest FPU context 4049644 cycles
NOTE: I didn't have a patch in place to isolate the counts for each variation
(ssse3 vs. avx vs. avx2) and
- for sha512: sha512 vs. sha384
- for sha256: sha256 vs. sha224
so the numbers include sha256 and sha512 running twice as many tests
as sha1.
This approach looks very good:
- 16% of the number of begin/end calls
- 10% of the CPU cycles spent making the calls
- the FPU context is held for a long time (77 ms) but only while
it's not needed.
That's much more efficient than releasing it every 30 us just in case.
I'll keep testing this to make sure RCU stalls stay away, and apply
the approach to the other algorithms.
In x86, need_resched() has to deal with a PER_CPU variable, so I'm
not sure it's worth the hassle to figure out how to do that from
assembly code.

How recently did you make this change? I implemented this conditional
approach for ecb_cbc_helpers.h, but saw no changes at all to performance
on serpent-avx2 and twofish-avx.
kernel_fpu_{begin,end} (after the first call to begin) don't do anything
more than enable/disable preemption and make a few writes to the mxcsr.
It's likely that the above approach has the tiniest bit less overhead,
and it will preempt on non CONFIG_PREEMPT kernels, but nothing suggests
a performance uplift.
This brings us back to this question: should crypto routines be
preempted under PREEMPT_VOLUNTARY or not?

I missed the earlier discussions. Have you seen issues with RCU
stalls/latency spikes because of crypto routines? If so, what preemption
model were you running?

Leave it in c. It'll be more maintainable that way.

The hash functions are the main problem; the skciphers receive
requests already broken into 4 KiB chunks by the SG list helpers.

While running Wireshark in Fedora, I noticed the top function consuming
CPU cycles (per "perf top") was sha512_generic.
Although Fedora and RHEL have the x86 optimized driver compiled as a
module, nothing in the distro or application space noticed it was there
and loaded it. The only x86 optimized drivers that do get used are the
ones built-in to the kernel.
After making changes to load the x86 sha512 module, I noticed several
boots over the next few weeks reported RCU stalls, all in the sha512_avx2
function. Because the stack traces take a long time to print to the
serial port, these can trigger soft lockups as well. Fedora and RHEL
default to "Voluntary Kernel Preemption (Desktop)":
# CONFIG_PREEMPT_NONE is not set
CONFIG_PREEMPT_VOLUNTARY=y
# CONFIG_PREEMPT is not set
The reason was that sha512 and all the other x86 crypto hash functions
process the entire data in one kernel_fpu_begin()/end() block, which
blocks preemption. Each boot checks module signatures for about 4000
files, totaling about 2.4 GB. Breaking the loops into smaller chunks
fixes the problem. However, since functions like crc32c are 20x faster
than sha1, one value like 4 KiB is not ideal.
A few non-hash functions have issues too. Although most skciphers are
broken up into 4 KiB chunks by the sg list walking functions, aegis
packs everything inside one kernel_fpu_begin()/end() block. All the
aead functions handle the main data with sg list walking functions,
but handle all the associated data inside one kernel_fpu_begin()/end()
block.

I'm testing a new kernel_fpu_yield() utility function that looks nice:
void __sha1_transform_avx2(struct sha1_state *state, const u8 *data, int blocks)
{
if (blocks <= 0)
return;
kernel_fpu_begin();
for (;;) {
const int chunks = min(blocks, 4096 / SHA1_BLOCK_SIZE);
sha1_transform_avx2(state->state, data, chunks);
blocks -= chunks;
if (blocks <= 0)
break;
data += chunks * SHA1_BLOCK_SIZE;
kernel_fpu_yield();
}
kernel_fpu_end();
}
This construction also makes it easy to add debug counters to
observe what is happening.
In a boot with preempt=none and the crypto extra self-tests
enabled, two modules benefitted from that new yield call:
/sys/module/sha256_ssse3/parameters/fpu_rescheds:3
/sys/module/sha512_ssse3/parameters/fpu_rescheds:515
10 passes of 1 MiB buffer tests on all the drivers
shows several others benefitting:

I'll keep experimenting with all the preempt modes, heavier
workloads, and shorter RCU timeouts to confirm this solution
is robust. It might even be appropriate for the generic
drivers, if they suffer from the problems that sm4 shows here.

I think so. The RCU stall and soft lockup detectors aren't disabled,
so there is still an expectation of sharing the CPUs even in
PREEMPT=none mode.
1 MiB tests under CONFIG_PREEMPT=none triggered soft lockups while
running CBC mode for SM4, Camellia, and Serpent:

SM4 falls back to the generic driver for encryption; it only has
optimized decryption functions. Therefore, it doesn't make any
kernel_fpu_end() calls and thus makes no rescheduling calls.
This shows the CPU cycles for 1 MiB of encrypt and decrypt for
each algorithm (no soft lockups this time). SM4, Serpent, Cast5,
and Cast6 encryption in CBC mode are the slowest by far.

I have a set of patches that's looking promising. It's no longer
generating RCU stall warnings or soft lockups with either x86
drivers or generic drivers (sm4 is particularly taxing).
Test case:
* added 28 clones of the tcrypt module so modprobe can run it
many times in parallel (1 thread per CPU core)
* added 1 MiB big buffer functional tests (compare to
generic results)
* added 1 MiB big buffer speed tests
* 3 windows running
* 28 threads running
* modprobe with each defined test mode in order 1, 2, 3, etc.
* RCU stall timeouts set to shortest supported values
* run in preempt=none, preempt=voluntary, preempt=full modes
Patches include:
* Ard's kmap_local() patch
* Suppress RCU stall warnings during speed tests. Change the
rcu_sysrq_start()/end() functions to be general purpose and
call them from tcrypt test functions that measure time of
a crypto operation
* add crypto_yield() unilaterally in skcipher_walk_done so
it is run even if data is aligned
* add crypto_yield() in aead_encrypt/decrypt so they always
call it like skcipher
* add crypto_yield() at the end each hash update(), digest(),
and finup() function so they always call it like skcipher
* add kernel_fpu_yield() calls every 4 KiB inside x86
kernel_fpu_begin()/end() blocks, so the x86 functions always
yield to the scheduler even when they're bypassing those
helper functions (that now call crypto_yield() more
consistently)
I'll keep trying to break it over the weekend. If it holds
up I'll post the patches next week.

That happens under CONFIG_PREEMPTION=y (from include/Linux/preempt.h and arch/x86/include/asm/preempt.h) Is calling cond_resched() still helpful if that is not the configuration?

Perhaps, but then again perhaps if preemption is off, maybe we shouldn't even bother with the 4K split. Were the initial warnings with or without preemption? Personally I don't really care since I always use preemption. The PREEMPT Kconfigs do provide a bit of nuance with the split between PREEMPT_NONE vs. PREEMPT_VOLUNTARY.

I was thinking about this a few days ago, and my 2¢ is that it's
probably best to not preempt the kernel in the middle of a crypto
operation under PREEMPT_VOLUNTARY. We're already not preempting during
these operations, and there haven't been complaints of excessive latency
because of these crypto operations.
If we skip the kernel_fpu_{begin,end} pair when not under
CONFIG_PREEMPT, we'll save a significant cycle count that is wasted
currently. See Elliot Robert's numbers on conditional begin/end in sha
to see the benefits of not saving/restoring unnecessarily: "10% of the
CPU cycles spent making the [kernel_fpu_{begin,end}] calls".
> I'll leave it to you to decide :)
One extra thought: commit 827ee47: "crypto: x86 - add some helper macros
for ECB and CBC modes" makes a mention of fpu save/restore being done
lazily. I don't know the details, so would that change this discussion?
Thanks for listening,

Probably because the people who have been suffering from (and looking for) latency issues aren't running crypto tests. I've found some terrible pre-emption latency issues trying to get RT processes scheduled in a sensible timeframe. I wouldn't worry about 100us - I'm doing audio processing every 10ms, but anything much longer causes problems when trying to use 90+% of the cpu time for lots of audio channels. I didn't try a CONFIG_RT kernel, the application needs to run on a standard 'distro' kernel. In any case I suspect all the extra processes switches (etc) the RT kernel adds will completely kill performance. I wonder how much it would cost to measure the time spent with pre-empt disabled (and not checked) and to trace long intervals.

On arm64, this is implemented in an assembler macro 'cond_yield' so we
don't need to preserve/restore the SIMD state state at all if the
yield is not going to result in a call to schedule(). For example, the
SHA3 code keeps 400 bytes of state in registers, which we don't want
to save and reload unless needed. (5f6cb2e617681 'crypto:
arm64/sha512-ce - simplify NEON yield')
So the asm routines will call cond_yield, and return early if a yield
is required, with the number of blocks or bytes left to process as the
return value. The C wrapper just calls the asm routine in a loop until
the return value becomes 0.
That way, we don't need magic values at all, and the yield will occur
as soon as the asm inner loop observes the yield condition so the
latency should be much lower as well.
Note that it is only used in shash implementations, given that they
are the only ones that may receive unbounded inputs.

(5f6cb2e617681 'crypto: > arm64/sha512-ce - simplify NEON yield') That sounds like the optimal approach. There is a cost to unnecessary kernel_fpu_begin()/end() calls - increasing their usage in the x86 sha512 driver added 929 us during one boot. The cond_yield check is just a few memory reads and conditional branches. I see that is built on the asm-offsets.c technique mentioned by Dave Hansen in the x86 aria driver thread. > Note that it is only used in shash implementations, given that they > are the only ones that may receive unbounded inputs. Although typical usage probably doesn't stress this, the length of the additional associated data presented to aead implementations is unconstrained as well. At least in x86, they can end up processing multiple megabytes in one chunk like the hash functions (if the associated data is a big buffer described by a sg list created with sg_init_one()).

Reviewing the two arm64 aead drivers, aes-ce-ccm-glue.c solves that by
including this in the do/while loop in ccm_calculate_auth_mac():
n = min_t(u32, n, SZ_4K); /* yield NEON at least every 4k */
That was added by 36a916af641 ("crypto: arm64/aes-ccm - yield NEON

Using crc32c-intel as an example, the gcc 12.2.1 assembly output is the
same for:
1. const variable per-module
static const unsigned int bytes_per_fpu = 868 * 1024;
2. enum per-module
enum { bytes_per_fpu = 868 * 1024 } ;
3. enum per function (_update and _finup)
enum { bytes_per_fpu = 868 * 1024 } ;
Each function gets a movl instruction with that constant, and has the
same compare, add, subtract, and jump instructions.
# ../arch/x86/crypto/crc32c-intel_glue.c:198: unsigned int chunk = min(len, bytes_per_fpu);
movl $888832, %eax #, tmp127
# ../arch/x86/crypto/crc32c-intel_glue.c:171: unsigned int chunk = min(len, bytes_per_fpu);
movl $888832, %r13d #, tmp128
Since enum doesn't guarantee any particular type, those variations
upset the min() macro. min_t() is necessary to eliminate the
compiler warning.
../arch/x86/crypto/crc32c-intel_glue.c: In function ‘crc32c_pcl_intel_update’:

> Also, where did you get this number? Seems kind of weird.
As described in replies on the v2 patches, I created a tcrypt test that
runs each algorithm on a 1 MiB buffer with no loop limits (and irqs
disabled), picks the best result out of 10 passes, and calculates the
number of bytes that nominally fit in 30 us (on a 2.2 GHz Cascade
Lake CPU).
Actual results with those values vary from 37 to 102 us; it is much
better than running unlimited, but still imperfect.
https://lore.kernel.org/lkml/MW5PR84MB184284FBED63E2D043C93A6FAB369@MW5PR84MB1842.NAMPRD84.PROD.OUTLOOK.COM/
The hash algorithms seem to congregate around three speeds:
- slow: 10 to 20 KiB for sha* and sm3
- medium: 200 to 400 KiB for poly*
- fast: 600 to 800 KiB for crc*
so it might be preferable to just go with three values (e.g., 16, 256, and
512 KiB). There's a lot of variability in CPU architecture, CPU speeds, and
other system activity that make this impossible to perfect.
It'd be ideal if the loops checked the CPU cycle count rather than
worked on a byte count, but the RDTSC instruction is notoriously slow and
would slow down overall performance.
The RAID6 library supports running a benchmark during each boot to pick
the best implementation to use (not always enabled):
[ 3.341372] raid6: skipped pq benchmark and selected avx512x4
The crypto subsystem does something similar with its self-tests, which could
be expanded to include speed tests to tune the loop values. However, that
slows down boot and could be misled by an NMI or SMI during the test, which
could lead to even worse results.
The selected values could be kept in each file or put in a shared .h file.
Both approaches seem difficult to maintain.
The powerpc modules have paragraph-sized comments explaining their MAX_BYTES
macros (e.g., in arch/powerpc/crypto/sha256-spe-glue.c) that might be a good
model for documenting the values:
* MAX_BYTES defines the number of bytes that are allowed to be processed
* between preempt_disable() and preempt_enable(). SHA256 takes ~2,000
* operations per 64 bytes. e500 cores can issue two arithmetic instructions
* per clock cycle using one 32/64 bit unit (SU1) and one 32 bit unit (SU2).
* Thus 1KB of input data will need an estimated maximum of 18,000 cycles.
* Headroom for cache misses included. Even with the low end model clocked
* at 667 MHz this equals to a critical time window of less than 27us.

That just makes sure someone editing the source code doesn't pick a value that
will cause the loops to hang; it's stronger than a comment saying "don't set
this to 0". It's only a compile-time check, and doesn't result in any
the assembly language output that I can see.

Each module's assembly function can have different handling of
- length 0
- length < block size
- length < some minimum length
- length < a performance switchover point
- length not a multiple of block size
- current buffer pointer not aligned to block size
Sometimes the C glue logic checks values upfront; sometimes
it doesn't.
The while loops help get them to follow one of two patterns:
while (length)
or
while (length >= BLOCK_SIZE)
and sidestep some of the special handling concerns.
Performance-wise, the patches are either
- adding lots of kernel_fpu_begin() and kernel_fpu_end() calls
(all the ones that were running unlimited)
- removing lots of kernel_fpu_begin() and kernel_fpu_end() calls
(e.g., polyval relaxed from 4 KiB to 383 KiB)
which is much more impactful than the common while loop entry.
I created tcrypt tests that try lengths around all the special
values like 0, 16, 4096, and the selected bytes per FPU size
(comparing results to the generic algorithms like the extended
self-tests), so I think these loops are functionally correct
(I've found that violating the undocumented assumptions of the
assembly functions is a good way to exercise RCU stall
reporting).
From: Elliott, Robert > Sent: 22 November 2022 05:06 ... > Since enum doesn't guarantee any particular type, those variations > upset the min() macro. min_t() is necessary to eliminate the > compiler warning. Yes, min() is fundamentally broken. min_t() isn't really a solution. I think min() needs to include something like: #define min(a, b) \ __builtin_constant(b) && (b) + 0u <= MAX_INT ? \ ((a) < (int)(b) ? (a) : (int)(b)) : \ ... So in the common case where 'b' is a small constant integer it doesn't matter whether the is it signed or unsigned. I might try compiling a kernel where min_t() does that instead of the casts - just to see how many of the casts are actually needed.

Make kernel_fpu_begin() and kernel_fpu_end() calls around each
assembly language function that uses FPU context, rather than
around the entire set (init, ad, crypt, final).
Limit the processing of bulk data based on a module parameter,
so multiple blocks are processed within one FPU context
(associated data is not limited).
Allow the skcipher_walk functions to sleep again, since they are
is no longer called inside FPU context.
Motivation: calling crypto_aead_encrypt() with a single scatter-gather
list entry pointing to a 1 MiB plaintext buffer caused the aesni_encrypt
function to receive a length of 1048576 bytes and consume 306348 cycles
within FPU context to process that data.

2.38.1Narrow the kernel_fpu_begin()/kernel_fpu_end() to just wrap the
assembly functions, not any extra C code around them (which includes
several memcpy() calls).
This reduces unnecessary time in FPU context, in which the scheduler
is prevented from preempting and the RCU subsystem is kept from
doing its work.
Example results measuring a boot, in which SHA-512 is used to check all
module signatures using finup() calls:
Before:
calls maxcycles bpf update finup algorithm module
======== ============ ======== ======== ======== =========== ==============
168390 1233188 19456 0 19456 sha512-avx2 sha512_ssse3
After:
182694 1007224 19456 0 19456 sha512-avx2 sha512_ssse3
That means it stayed in FPU context for 226k fewer clocks cycles (which
is 102 microseconds on this system, 18% less).

2.38.1Change the type of the GCM auth_tag_len argument and derivative
variables from unsigned long to unsigned int, so they preserve the
type returned by crypto_aead_authsize().
Continue to pass it to the asm functions as an unsigned long,
but let those function calls be the place where the conversion
to the possibly larger type occurs.
This avoids possible truncation for calculations like:
scatterwalk_map_and_copy(auth_tag_msg, req->src,
req->assoclen + req->cryptlen - auth_tag_len,
auth_tag_len, 0);
whose third argument is an unsigned int. If unsigned long were
bigger than unsigned int, that equation could wrap.
Use unsigned int rather than int for intermediate variables
containing byte counts and block counts, since all the functions
using them accept unsigned int arguments.

2.38.1Like commit aa031b8f702e ("crypto: x86/sha512 - load based on CPU
features"), add module aliases based on CPU feature bits for
modules not implementing hash algorithms:
aegis, aesni, aria
blake2s, blowfish
camellia, cast5, cast6, chacha, curve25519
des3_ede
serpent, sm4
twofish
Signed-off-by: Robert Elliott <elliott@hpe.com>
---
v4 Remove CPU feature checks that are unreachable because
x86_match_cpu already handles them. Make curve25519 match
on ADX and check BMI2.

Can the user still insmod this? If so, you can't remove the ADX check.
Ditto for rest of patch.
For modules that have multiple choices, add read-only module parameters
reporting which CPU features a module is using.
The parameters show up as follows for modules that modify the behavior
of their registered drivers or register additional drivers for
each choice:

/sys/module/aesni_intel/parameters/using_x86_avx2:1

Isn't chacha missing?
However, what's the point of any of this? Who benefits from this info?
If something seems slow, I'll generally look at perf top, which provides
this same thing.
Also, "using" isn't quite correct. Some AVX2 machines will never use any
ssse3 instructions, despite the code being executable.

This part I like.

And BMI2, not just ADX.
Don't refuse to load modules based on missing additional x86 features
(e.g., OSXSAVE) or x86 XSAVE features (e.g., YMM). Instead, load the module,
but don't register any crypto drivers. Report the fact that one or more
features are missing in a new missing_x86_features module parameter
(0 = no problems, 1 = something is missing; each module parameter
description lists all the features that it wants).
For the SHA functions that register up to four drivers based on CPU
features, report separate module parameters for each set:
missing_x86_features_avx2
missing_x86_features_avx

2.38.1Don't refuse to load modules on certain CPUs and print a message
to the console. Instead, load the module but don't register the
crypto functions, and report this condition via a new module
suboptimal_x86 module parameter with this description:
Crypto driver not registered because performance on this CPU would be suboptimal
Reword the descriptions of the existing force module parameter
to match this modified behavior:
force: Force crypto driver registration on suboptimal CPUs
Make the new module parameters readable via sysfs:
/sys/module/blowfish_x86_64/parameters/suboptimal_x86:0
/sys/module/camellia_x86_64/parameters/suboptimal_x86:0
/sys/module/des3_ede_x86_64/parameters/suboptimal_x86:1
/sys/module/twofish_x86_64_3way/parameters/suboptimal_x86:1
If the module has been loaded and is reporting suboptimal_x86=1,
remove it to try loading again:
modprobe -r blowfish_x86_64
modprobe blowfish_x86_64 force=1
or specify it on the kernel command line:
blowfish_x86_64.force=1

2.37.3commit 2af632996b89 ("crypto: tcrypt - reschedule during speed tests")
added cond_resched() calls to "Avoid RCU stalls in the case of
non-preemptible kernel and lengthy speed tests by rescheduling when
advancing from one block size to another."
It only makes those calls if the sec module parameter is used
(run the speed test for a certain number of seconds), not the
default "cycles" mode.
Expand those to also run in "cycles" mode to reduce the rate
of rcu stall warnings:

2.37.3Limit the number of bytes processed between kernel_fpu_begin() and
kernel_fpu_end() calls.
Those functions call preempt_disable() and preempt_enable(), so
the CPU core is unavailable for scheduling while running.
This leads to "rcu_preempt detected expedited stalls" with stack dumps
pointing to the optimized hash function if the module is loaded and
used a lot:
rcu: INFO: rcu_preempt detected expedited stalls on CPUs/tasks: ...
For example, that can occur during boot with the stack track pointing
to the sha512-x86 function if the system set to use SHA-512 for
module signing. The call trace includes:
module_sig_check
mod_verify_sig
pkcs7_verify
pkcs7_digest
sha512_finup
sha512_base_do_update
Fixes: 66be89515888 ("crypto: sha1 - SSSE3 based SHA1 implementation for x86-64")
Fixes: 8275d1aa6422 ("crypto: sha256 - Create module providing optimized SHA256 routines using SSSE3, AVX or AVX2 instructions.")

v3 simplify to while loops rather than do..while loops, avoid
redundant checks for zero length, rename the limit macro and
change into a const, vary the limit for each algo

v3 use while loops and static int, simplify one of the loop structures,
add algorithm-specific limits, use local stack variable in crc32 finup
rather than the context pointer like update uses

2.37.3Don't register and unregister each of the functions from least-
to most-optimized (e.g., SSSE3 then AVX then AVX2); register all
variations.
This enables selecting those other algorithms if needed,
such as for testing with:
modprobe tcrypt mode=300 alg=sha512-avx
modprobe tcrypt mode=400 alg=sha512-avx

v3 register all the variations, not just the best one, per
Herbert's feedback. return -ENODEV if none are successful, 0
if any are successful

Narrow the kernel_fpu_begin()/kernel_fpu_end() to just wrap the
assembly functions, not any extra C code around them (which includes
several memcpy() calls).
This reduces unnecessary time in FPU context, in which the scheduler
is prevented from preempting and the RCU subsystem is kept from
doing its work.
Example results measuring a boot, in which SHA-512 is used to check all
module signatures using finup() calls:
Before:
calls maxcycles bpf update finup algorithm module
======== ============ ======== ======== ======== =========== ==============
168390 1233188 19456 0 19456 sha512-avx2 sha512_ssse3
After:
182694 1007224 19456 0 19456 sha512-avx2 sha512_ssse3
That means it stayed in FPU context for 226k fewer clocks cycles (which
is 102 microseconds on this system, 18% less).

I've instrumented all the x86 crypto modules, including ways to
experiment with different loop sizes. Here are some results with
the hash functions.
Key:
calls = number of kernel_fpu_begin()/end() calls made by the module
cost = number of CPU cycles consumed by those calls (overhead)
maxcycles = number of CPU cycles between those calls in FPU context
bpf = bytes_per_fpu loop size
KiB = bpf expressed in KiB
maxlen = maximum number of bytes per loop via update()
maxlen2 = maximum number of bytes per loop via finup()
This is on a 2.2 GHz Cascade Lake CPU, where each cycle is nominally
0.45 ns. The CPU does not support SHA-NI instructions, so those
results are missing.
Here are the results from a boot with the avx2 bytes_per_fpu values set
to 0 (unlimited - original behavior).
Booting includes:
- processing 2.3 GB of SHA-512 kernel module hashes
- crypto self-tests
- crypto extra self-tests (CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y)
calls cost maxcycles bpf KiB maxlen maxlen2 algorithm module

The self-tests only test small data sets (even the extra tests
limit themselves to PAGE_SIZE * 2) so only the sha512_ssse3
module was stressed with large requests.
The cost of the kernel_fpu_begin()/end() calls (2044882 cycles) was
929 us, and the longest time in FPU context (164510724) was 75 ms.
I think the biggest file it encounters is:
-rw-r--r--. 1 root root 48186713 Nov 1 13:14 /lib/modules/6.0.0+/kernel/fs/xfs/xfs.ko
I added tcrypt tests to exercise each driver ten times with 1 MiB data,
and that exposes all the drivers to larger requests.

Setting bpf limits based on those results narrows the maxcycles in
FPU context. I've seen results vary from 81912 (37 us) to
(102 us) - not real tight, but much better than ranging up
to 75 ms.

If I reboot with sha512-avx2 set to 20 KiB, the sha512-avx2
maxlength can still take a long time (e.g., 2 ms). That's much
better than the original 75 ms, but still not in the 50 us range.
I set /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor to
"performance" in .bash_profile, but that's not effective during
boot, so maybe that is the source of variability.
Example boot with 20 KiB limit:
calls cost maxcycles bpf KiB maxlen maxlen2 algorithm module

161011 16232280 4049644 20480 20 0 20480 sha512-avx2 sha512_ssse3
Limiting it to 1 KiB does reduce maxcycles to the us range, but
the cost of all the extra calls soars.
So, for v3 of the series, I plan to propose values ranging from:
- 11 to 20 KiB for sha* amd sm3
- 200 to 400 Kib for *poly*
- 600 to 800 KiB for crc*
v3 will only cover the hash functions - skcipher and aead
have some unique challenges that we can tackle later.
