Nick Desaulniers	7c29fd8317	lib/string.c: implement stpcpy ... commit 1e1b6d63d6 upstream. LLVM implemented a recent "libcall optimization" that lowers calls to `sprintf(dest, "%s", str)` where the return value is used to `stpcpy(dest, str) - dest`. This generally avoids the machinery involved in parsing format strings. `stpcpy` is just like `strcpy` except it returns the pointer to the new tail of `dest`. This optimization was introduced into clang-12. Implement this so that we don't observe linkage failures due to missing symbol definitions for `stpcpy`. Similar to last year's fire drill with: commit 5f074f3e19 ("lib/string.c: implement a basic bcmp") The kernel is somewhere between a "freestanding" environment (no full libc) and "hosted" environment (many symbols from libc exist with the same type, function signature, and semantics). As Peter Anvin notes, there's not really a great way to inform the compiler that you're targeting a freestanding environment but would like to opt-in to some libcall optimizations (see pr/47280 below), rather than opt-out. Arvind notes, -fno-builtin-* behaves slightly differently between GCC and Clang, and Clang is missing many __builtin_* definitions, which I consider a bug in Clang and am working on fixing. Masahiro summarizes the subtle distinction between compilers justly: To prevent transformation from foo() into bar(), there are two ways in Clang to do that; -fno-builtin-foo, and -fno-builtin-bar. There is only one in GCC; -fno-buitin-foo. (Any difference in that behavior in Clang is likely a bug from a missing __builtin_* definition.) Masahiro also notes: We want to disable optimization from foo() to bar(), but we may still benefit from the optimization from foo() into something else. If GCC implements the same transform, we would run into a problem because it is not -fno-builtin-bar, but -fno-builtin-foo that disables that optimization. In this regard, -fno-builtin-foo would be more future-proof than -fno-built-bar, but -fno-builtin-foo is still potentially overkill. We may want to prevent calls from foo() being optimized into calls to bar(), but we still may want other optimization on calls to foo(). It seems that compilers today don't quite provide the fine grain control over which libcall optimizations pseudo-freestanding environments would prefer. Finally, Kees notes that this interface is unsafe, so we should not encourage its use. As such, I've removed the declaration from any header, but it still needs to be exported to avoid linkage errors in modules.

Jim Cromie	2661310337	dyndbg: fix a BUG_ON in ddebug_describe_flags ... [ Upstream commit f678ce8cc3 ] ddebug_describe_flags() currently fills a caller provided string buffer, after testing its size (also passed) in a BUG_ON. Fix this by replacing them with a known-big-enough string buffer wrapped in a struct, and passing that instead. Also simplify ddebug_describe_flags() flags parameter from a struct to a member in that struct, and hoist the member deref up to the caller. This makes the function reusable (soon) where flags are unpacked.

Linus Torvalds	e6b7c5f7a4	random32: remove net_rand_state from the latent entropy gcc plugin ... commit 83bdc7275e upstream. It turns out that the plugin right now ends up being really unhappy about the change from 'static' to 'extern' storage that happened in commit f227e3ec3b ("random32: update the net random state on interrupt and activity"). This is probably a trivial fix for the latent_entropy plugin, but for now, just remove net_rand_state from the list of things the plugin worries about.

Willy Tarreau	29204c8468	random32: update the net random state on interrupt and activity ... commit f227e3ec3b upstream. This modifies the first 32 bits out of the 128 bits of a random CPU's net_rand_state on interrupt or CPU activity to complicate remote observations that could lead to guessing the network RNG's internal state. Note that depending on some network devices' interrupt rate moderation or binding, this re-seeding might happen on every packet or even almost never. In addition, with NOHZ some CPUs might not even get timer interrupts, leaving their local state rarely updated, while they are running networked processes making use of the random state. For this reason, we also perform this update in update_process_times() in order to at least update the state when there is user or system activity, since it's the only case we care about.

Jann Horn	c1d9c6995d	lib/zlib: remove outdated and incorrect pre-increment optimization ... [ Upstream commit acaab7335b ] The zlib inflate code has an old micro-optimization based on the assumption that for pre-increment memory accesses, the compiler will generate code that fits better into the processor's pipeline than what would be generated for post-increment memory accesses. This optimization was already removed in upstream zlib in 2016: https://github.com/madler/zlib/commit/9aaec95e8211 This optimization causes UB according to C99, which says in section 6.5.6 "Additive operators": "If both the pointer operand and the result point to elements of the same array object, or one past the last element of the array object, the evaluation shall not produce an overflow; otherwise, the behavior is undefined". This UB is not only a theoretical concern, but can also cause trouble for future work on compiler-based sanitizers. According to the zlib commit, this optimization also is not optimal anymore with modern compilers. Replace uses of OFF, PUP and UP_UNALIGNED with their definitions in the POSTINC case, and remove the macro definitions, just like in the upstream patch.

This special case for umul_ppmm for MIPS64r6 was added in commit bbc25bee37 ("lib/mpi: Fix umul_ppmm() for MIPS64r6"), due to GCC being inefficient and emitting a __multi3 intrinsic. There is no such issue with clang; with this patch applied, I can build this configuration without any problems and there are no link errors like mentioned in the commit above (which I can still reproduce with GCC 9.3.0 when that commit is reverted). Only use this definition when GCC is being used. This really should have been caught by commit b0c091ae04 ("lib/mpi: Eliminate unused umul_ppmm definitions for MIPS") when I was messing around in this area but I was not testing 64-bit MIPS at the time.

Christophe Leroy	e18590b3e2	lib: Reduce user_access_begin() boundaries in strncpy_from_user() and strnlen_user() ... commit ab10ae1c3b upstream. The range passed to user_access_begin() by strncpy_from_user() and strnlen_user() starts at 'src' and goes up to the limit of userspace although reads will be limited by the 'count' param. On 32 bits powerpc (book3s/32) access has to be granted for each 256Mbytes segment and the cost increases with the number of segments to unlock. Limit the range with 'count' param.

Linus Torvalds	216284c4a1	make 'user_access_begin()' do 'access_ok()' ... commit 594cc251fd upstream. Originally, the rule used to be that you'd have to do access_ok() separately, and then user_access_begin() before actually doing the direct (optimized) user access. But experience has shown that people then decide not to do access_ok() at all, and instead rely on it being implied by other operations or similar. Which makes it very hard to verify that the access has actually been range-checked. If you use the unsafe direct user accesses, hardware features (either SMAP - Supervisor Mode Access Protection - on x86, or PAN - Privileged Access Never - on ARM) do force you to use user_access_begin(). But nothing really forces the range check. By putting the range check into user_access_begin(), we actually force people to do the right thing (tm), and the range check vill be visible near the actual accesses. We have way too long a history of people trying to avoid them.

For the stack protector, we already attempt to disable it, but this fails on clang because the check is mixed with the gcc specific -fno-conserve-stack option. According to Andrey Ryabinin, that option is not even needed, dropping it here fixes the stackprotector issue.

Thomas Gleixner	7deebec2f3	UPSTREAM: lib/vdso/32: Remove inconsistent NULL pointer checks ... The 32bit variants of vdso_clock_gettime()/getres() have a NULL pointer check for the timespec pointer. That's inconsistent vs. 64bit. But the vdso implementation will never be consistent versus the syscall because the only case which it can handle is NULL. Any other invalid pointer will cause a segfault. So special casing NULL is not really useful. Remove it along with the superflouos syscall fallback invocation as that will return -EFAULT anyway. That also gets rid of the dubious typecast which only works because the pointer is NULL.

Thomas Gleixner	941fb316b4	UPSTREAM: lib/vdso: Make delta calculation work correctly ... The x86 vdso implementation on which the generic vdso library is based on has subtle (unfortunately undocumented) twists: 1) The code assumes that the clocksource mask is U64_MAX which means that no bits are masked. Which is true for any valid x86 VDSO clocksource. Stupidly it still did the mask operation for no reason and at the wrong place right after reading the clocksource. 2) It contains a sanity check to catch the case where slightly unsynchronized TSC values can be observed which would cause the delta calculation to make a huge jump. It therefore checks whether the current TSC value is larger than the value on which the current conversion is based on. If it's not larger the base value is used to prevent time jumps. reason it is also completely wrong for clocksources with a smaller mask which can legitimately wrap around during a conversion period. The core timekeeping code does it correct by applying the mask after the delta calculation: (now - base) & mask around during a conversion period because there the now > base check is just wrong and causes stale time stamps and time going backwards issues. Unbreak it by: 1) Removing the mask operation from the clocksource read which makes the fallback detection work for all clocksources 2) Replacing the conditional delta calculation with a overrideable inline function. results in a significant performance hit for the x86 VSDO. The timekeeping core code must have the non optimized version as it has to operate correctly with clocksources which have smaller masks as well to handle the case where TSC is discarded as timekeeper clocksource and replaced by HPET or pmtimer. For the VDSO there is no replacement clocksource. If TSC is unusable the syscall is enforced which does the right thing. To accommodate to the needs of various architectures provide an override-able inline function which defaults to the regular delta calculation with masking: (now - base) & mask Override it for x86 with the non-masking and checking version. This unbreaks the ARM64 syscall fallback operation, allows to use clocksources with arbitrary width and preserves the performance optimization for x86.

ndesaulniers@google.com	00dd1df3c2	lib/raid6: use vdupq_n_u8 to avoid endianness warnings ... commit 1ad3935b39 upstream. Clang warns: vector initializers are not compatible with NEON intrinsics in big endian mode [-Wnonportable-vector-initialization] While this is usually the case, it's not an issue for this case since we're initializing the uint8x16_t (16x uint8_t's) with the same value. Instead, use vdupq_n_u8 which both compilers lower into a single movi instruction: https://godbolt.org/z/vBrgzt This avoids the static storage for a constant value.

Yury Norov	9af535dc01	uapi: rename ext2_swab() to swab() and share globally in swab.h ... [ Upstream commit d5767057c9 ] ext2_swab() is defined locally in lib/find_bit.c However it is not specific to ext2, neither to bitmaps. There are many potential users of it, so rename it to just swab() and move to include/uapi/linux/swab.h ABI guarantees that size of unsigned long corresponds to BITS_PER_LONG, therefore drop unneeded cast.

Kees Cook	4052265b8b	FROMLIST: lib: test_stackinit.c: XFAIL switch variable init tests ... The tests for initializing a variable defined between a switch statement's test and its first "case" statement are currently not initialized in Clang[1] nor the proposed auto-initialization feature in GCC. We should retain the test (so that we can evaluate compiler fixes), but mark it as an "expected fail". The rest of the kernel source will be adjusted to avoid this corner case. Also disable -Wswitch-unreachable for the test so that the intentionally broken code won't trigger warnings for GCC (nor future Clang) when initialization happens this unhandled place.
