From b531ca5e3ac7e3810e9331ff437ca8912978e2a7 Mon Sep 17 00:00:00 2001 From: Wang Mingyu Date: Mon, 13 Feb 2023 10:37:52 +0800 Subject: [PATCH] libjpeg-turbo: upgrade 2.1.5 -> 2.1.5.1 Changelog: ========== 1. The SIMD dispatchers in libjpeg-turbo 2.1.4 and prior stored the list of supported SIMD instruction sets in a global variable, which caused an innocuous race condition whereby the variable could have been initialized multiple times if 'jpeg_start_*compress()' was called simultaneously in multiple threads. libjpeg-turbo 2.1.5 included an undocumented attempt to fix this race condition by making the SIMD support variable thread-local. However, that caused another issue whereby, if 'jpeg_start_*compress()' was called in one thread and 'jpeg_read_*()' or 'jpeg_write_*()' was called in a second thread, the SIMD support variable was never initialized in the second thread. On x86 systems, this led the second thread to incorrectly assume that AVX2 instructions were always available, and when it attempted to use those instructions on older x86 CPUs that do not support them, an illegal instruction error occurred. The SIMD dispatchers now ensure that the SIMD support variable is initialized before dispatching based on its value.
