Merge tag 'random-6.12-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator updates from Jason Donenfeld: "Originally I'd planned on sending each of the vDSO getrandom() architecture ports to their respective arch trees. But as we started to work on this, we found lots of interesting issues in the shared code and infrastructure, the fixes for which the various archs needed to base their work.
So in the end, this turned into a nice collaborative effort fixing up issues and porting to 5 new architectures -- arm64, powerpc64, powerpc32, s390x, and loongarch64 -- with everybody pitching in and commenting on each other's code. It was a fun development cycle.
This contains:
- Numerous fixups to the vDSO selftest infrastructure, getting it running successfully on more platforms, and fixing bugs in it.
- Additions to the vDSO getrandom & chacha selftests. Basically every time manual review unearthed a bug in a revision of an arch patch, or an ambiguity, the tests were augmented.
By the time the last arch was submitted for review, s390x, v1 of the series was essentially fine right out of the gate.
- Fixes to the the generic C implementation of vDSO getrandom, to build and run successfully on all archs, decoupling it from assumptions we had (unintentionally) made on x86_64 that didn't carry through to the other architectures.
- Port of vDSO getrandom to LoongArch64, from Xi Ruoyao and acked by Huacai Chen.
- Port of vDSO getrandom to ARM64, from Adhemerval Zanella and acked by Will Deacon.
- Port of vDSO getrandom to PowerPC, in both 32-bit and 64-bit varieties, from Christophe Leroy and acked by Michael Ellerman.
- Port of vDSO getrandom to S390X from Heiko Carstens, the arch maintainer.
While it'd be natural for there to be things to fix up over the course of the development cycle, these patches got a decent amount of review from a fairly diverse crew of folks on the mailing lists, and, for the most part, they've been cooking in linux-next, which has been helpful for ironing out build issues.
In terms of architectures, I think that mostly takes care of the important 64-bit archs with hardware still being produced and running production loads in settings where vDSO getrandom is likely to help.
Arguably there's still RISC-V left, and we'll see for 6.13 whether they find it useful and submit a port"

selftests: vDSO: fix vdso_config for s390

selftests: vDSO: fix vdso_config for s390
Running vdso_test_correctness on s390x (aka s390 64 bit) emits a warning:
Warning: failed to find clock_gettime64 in vDSO
This is caused by the "#elif defined (__s390__)" check in vdso_config.h which the defines VDSO_32BIT.
If __s390x__ is defined also __s390__ is defined. Therefore the correct check must make sure that only __s390__ is defined.
Therefore add the missing !defined(__s390x__). Also use common __s390x__ define instead of __s390X__.

Running vdso_test_correctness on powerpc64 gives the following warning:

Running vdso_test_correctness on powerpc64 gives the following warning:
~ # ./vdso_test_correctness Warning: failed to find clock_gettime64 in vDSO
This is because vdso_test_correctness was built with VDSO_32BIT defined.
__powerpc__ macro is defined on both powerpc32 and powerpc64 so __powerpc64__ needs to be checked first in vdso_config.h

Don't hard-code x86 specific names. Rather, use vdso_config definitions to find the correct function matching the architecture.
Add random VDSO function names in names[][]. Remove the #ifdef CONFIG_VDSO32, as having the name there all the time is harmless and guaranties a steady index for following strings.

selftests/vDSO: fix building errors on LoongArch
Patch series "selftests/vDSO: Fix errors on LoongArch", v4.
This patch (of 2):
There exist the following errors when build vDSO selftests on LoongArch:
# make headers && cd tools/testing/selftests/vDSO && make ... error: 'VDSO_VERSION' undeclared (first use in this function) ... error: 'VDSO_NAMES' undeclared (first use in this function)
We can see the following code in arch/loongarch/vdso/vdso.lds.S:
VERSION { LINUX_5.10 { global: __vdso_getcpu; __vdso_clock_getres; __vdso_clock_gettime; __vdso_gettimeofday; __vdso_rt_sigreturn; local: *; }; }
so VDSO_VERSION should be 6 and VDSO_NAMES should be 1 for LoongArch, add them to fix the building errors on LoongArch.
