* Linux: Pass size argument of epoll_create to the kernelFlorian Weimer2022-12-221-1/+1
| | | | | | | | | | | The kernel actually verifies it, and a garbage value in the register causes improper system call failures. Fixes commit c1c0dea38833751f36a145c32 ("Linux: Remove epoll_create, inotify_init from syscalls.list") and commit d1d23b134244d59c4d6ef2295 ("Lninux: consolidate epoll_create implementation").

* stdio-common: Convert vfprintf and related functions to buffersFlorian Weimer2022-12-195-101/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vfprintf is entangled with vfwprintf (of course), __printf_fp, __printf_fphex, __vstrfmon_l_internal, and the strfrom family of functions. The latter use the internal snprintf functionality, so vsnprintf is converted as well. The simples conversion is __printf_fphex, followed by __vstrfmon_l_internal and __printf_fp, and finally __vfprintf_internal and __vfwprintf_internal. __vsnprintf_internal and strfrom* are mostly consuming the new interfaces, so they are comparatively simple. __printf_fp is a public symbol, so the FILE *-based interface had to preserved. The __printf_fp rewrite does not change the actual binary-to-decimal conversion algorithm, and digits are still not emitted directly to the target buffer. However, the staging buffer now uses bytes instead of wide characters, and one buffer copy is eliminated. The changes are at least performance-neutral in my testing. Floating point printing and snprintf improved measurably, so that this Lua script for i=1,5000000 do print(i, i * math.pi) end runs about 5% faster for me. To preserve fprintf performance for a simple "%d" format, this commit has some logic changes under LABEL (unsigned_number) to avoid additional function calls. There are certainly some very easy performance improvements here: binary, octal and hexadecimal formatting can easily avoid the temporary work buffer (the number of digits can be computed ahead-of-time using one of the __builtin_clz* built-ins). Decimal formatting can use a specialized version of _itoa_word for base 10. The existing (inconsistent) width handling between strfmon and printf is preserved here. __print_fp_buffer_1 would have to use __translated_number_width to achieve ISO conformance for printf. Test expectations in libio/tst-vtables-common.c are adjusted because the internal staging buffer merges all virtual function calls into one. In general, stack buffer usage is greatly reduced, particularly for unbuffered input streams. __printf_fp can still use a large buffer in binary128 mode for %g, though.

* x86: Prevent SIGSEGV in memcmp-sse2 when data is concurrently modified [BZ ↵Noah Goldstein2022-12-151-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | #29863] In the case of INCORRECT usage of `memcmp(a, b, N)` where `a` and `b` are concurrently modified as `memcmp` runs, there can be a SIGSEGV in `L(ret_nonzero_vec_end_0)` because the sequential logic assumes that `(rdx - 32 + rax)` is a positive 32-bit integer. To be clear, this change does not mean the usage of `memcmp` is supported. The program behaviour is undefined (UB) in the presence of data races, and `memcmp` is incorrect when the values of `a` and/or `b` are modified concurrently (data race). This UB may manifest itself as a SIGSEGV. That being said, if we can allow the idiomatic use cases, like those in yottadb with opportunistic concurrency control (OCC), to execute without a SIGSEGV, at no cost to regular use cases, then we can aim to minimize harm to those existing users. The fix replaces a 32-bit `addl %edx, %eax` with the 64-bit variant `addq %rdx, %rax`. The 1-extra byte of code size from using the 64-bit instruction doesn't contribute to overall code size as the next target is aligned and has multiple bytes of `nop` padding before it. As well all the logic between the add and `ret` still fits in the same fetch block, so the cost of this change is basically zero. The relevant sequential logic can be seen in the following pseudo-code: ``` /* * rsi = a * rdi = b * rdx = len - 32 */ /* cmp a[0:15] and b[0:15]. Since length is known to be [17, 32] in this case, this check is also assumed to cover a[0:(31 - len)] and b[0:(31 - len)]. */ movups (%rsi), %xmm0 movups (%rdi), %xmm1 PCMPEQ %xmm0, %xmm1 pmovmskb %xmm1, %eax subl %ecx, %eax jnz L(END_NEQ) /* cmp a[len-16:len-1] and b[len-16:len-1]. */ movups 16(%rsi, %rdx), %xmm0 movups 16(%rdi, %rdx), %xmm1 PCMPEQ %xmm0, %xmm1 pmovmskb %xmm1, %eax subl %ecx, %eax jnz L(END_NEQ2) ret L(END2): /* Position first mismatch. */ bsfl %eax, %eax /* The sequential version is able to assume this value is a positive 32-bit value because the first check included bytes in range a[0:(31 - len)] and b[0:(31 - len)] so `eax` must be greater than `31 - len` so the minimum value of `edx` + `eax` is `(len - 32) + (32 - len) >= 0`. In the concurrent case, however, `a` or `b` could have been changed so a mismatch in `eax` less or equal than `(31 - len)` is possible (the new low bound is `(16 - len)`. This can result in a negative 32-bit signed integer, which when zero extended to 64-bits is a random large value this out out of bounds. */ addl %edx, %eax /* Crash here because 32-bit negative number in `eax` zero extends to out of bounds 64-bit offset. */ movzbl 16(%rdi, %rax), %ecx movzbl 16(%rsi, %rax), %eax ``` This fix is quite simple, just make the `addl %edx, %eax` 64 bit (i.e `addq %rdx, %rax`). This prevents the 32-bit zero extension and since `eax` is still a low bound of `16 - len` the `rdx + rax` is bound by `(len - 32) - (16 - len) >= -16`. Since we have a fixed offset of `16` in the memory access this must be in bounds.
* Allow _Qp_fgt in sparc64 localplt.dataJoseph Myers2022-12-131-0/+1
| | | | | | | | | | A recent GCC change resulted in localplt test failures on sparc64 because of references to _Qp_fgt. This is analogous to all the other floating-point symbols allowed in localplt.data, so it seems appropriate to allow this one as well.

* hurd: Make getrandom cache the server portSergey Bugaev2022-12-021-15/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, getrandom would, each time it's called, traverse the file system to find /dev/urandom, fetch some random data from it, then throw away that port. This is quite slow, while calls to getrandom are genrally expected to be fast. Additionally, this means that getrandom can not work when /dev/urandom is unavailable, such as inside a chroot that lacks one. User programs expect calls to getrandom to work inside a chroot if they first call getrandom outside of the chroot. In particular, this is known to break the OpenSSH server, and in that case the issue is exacerbated by the API of arc4random, which prevents it from properly reporting errors, forcing glibc to abort on failure. This causes sshd to just die once it tries to generate a random number. Caching the random server port, in a manner similar to how socket server ports are cached, both improves the performance and works around the chroot issue. Tested on i686-gnu with the following program: pthread_barrier_t barrier; void *worker(void*) { pthread_barrier_wait(&barrier); uint32_t sum = 0; for (int i = 0; i < 10000; i++) { sum += arc4random(); } return (void *)(uintptr_t) sum; } int main() { pthread_t threads[THREAD_COUNT]; pthread_barrier_init(&barrier, NULL, THREAD_COUNT); for (int i = 0; i < THREAD_COUNT; i++) { pthread_create(&threads[i], NULL, worker, NULL); } for (int i = 0; i < THREAD_COUNT; i++) { void *retval; pthread_join(threads[i], &retval); printf("Thread %i: %lu\n", i, (unsigned long)(uintptr_t) retval); } In my totally unscientific benchmark, with this patch, this completes in about 7 seconds, whereas previously it took about 50 seconds. This program was also used to test that getrandom () doesn't explode if the random server dies, but instead reopens the /dev/urandom anew. I have also verified that with this patch, OpenSSH can once again accept connections properly. Signed-off-by: Sergey Bugaev <bugaevc@gmail.com> Message-Id: <20221202135558.23781-1-bugaevc@gmail.com>

* LoongArch: Add support for scalbn[f]Xiaolin Tang2022-11-292-0/+58
| | | | | | | | Add inline assembler for the scalbn functions. Passes GLIBC regression. GCC 13, LoongArch support ___builtin_scalbn{,f} with -fno-math-errno, but only "libm" can use -fno-math-errno in GLIBC, and scalbn is in libc instead of libm because __printf_fp calls it.
