* mach: Fix passing -ffreestanding when checking for gnumach headersSamuel Thibault2022-12-192-12/+6
| | | | | | 8b8c768e3c70 ("Force use of -ffreestanding when checking for gnumach headers") was passing -ffreestanding to CFLAGS only, but headers checks are performed with the preprocessor, so we rather need to pass it to CPPFLAGS.

| | | | | | | Without this ./configure assumes that we are in a fully hosted environment, which might not be the case. After this patch, we can rely on the freestanding header files provided by GCC such as stdint.h. Message-Id: <Y5+0V9osFc/zXMq0@mars>

* 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. Tested with build-many-glibcs.py for sparc64-linux-gnu (GCC mainline), where it fixes the test failure.

* realloc: Return unchanged if request is within usable sizeSiddhesh Poyarekar2022-12-082-0/+33
| | | | | | | | | | | | | | | | | If there is enough space in the chunk to satisfy the new size, return the old pointer as is, thus avoiding any locks or reallocations. The only real place this has a benefit is in large chunks that tend to get satisfied with mmap, since there is a large enough spare size (up to a page) for it to matter. For allocations on heap, the extra size is typically barely a few bytes (up to 15) and it's unlikely that it would make much difference in performance. Also added a smoke test to ensure that the old pointer is returned unchanged if the new size to realloc is within usable size of the old pointer.

* 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>
