https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D253335 --- Comment #17 from commit-hook@FreeBSD.org --- A commit references this bug: Author: kevans Date: Fri Feb 26 04:54:03 UTC 2021 New revision: 566579 URL: https://svnweb.freebsd.org/changeset/ports/566579 Log: MFH: r566578 emulators/qemu-user-static: update to f7fd10d7677c This features a number of fixes; highlights: - Handle aarch64 YIELD instructions - Bump ARG_MAX to match the FreeBSD default on LP64 platforms - Implement __specialfd(2) and copy_file_range(2) - Style fixes - Fix an issue with binary execution[0] - Fix page fault handling for self-modifying binaries[1] - Suppress noise from CIOGSESSION usage and restore CRIOGET handling - Patch _umtx_op(2) through to the kernel where possible[2] [0] Attempting to execute a binary by name was broken when there was an unrelated entry by the same name in PWD. The report below observed it in= the cluster while building games/dobutsu, which tried to execute `xz` in a directory that had an `xz` directory inside of it. [1] From the fixing commit, qemu mprotect()s pages contained translated c= ode to PROT_READ | PROT_EXEC and upgrades protections as needed upon page fau= lt. This was broken in a previous commit that misidentified by the trap # that should have been observed. The observed issue a broken JIT compiler in libpcre. [2] _umtx_op can now be handled by the kernel in cases where the target l= ong size is not longer than the host, and the target and host are the same endianness. This is much more reliable than our previous emulation of th= ese operations, and should reduce hangs sometimes observed in threaded applications. Note that this requires a recent stable/12 or 13.x/-CURRENT.
