https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=295957 Alan Somers <asomers@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|New |Open Assignee|bugs@FreeBSD.org |asomers@FreeBSD.org --- Comment #1 from Alan Somers <asomers@FreeBSD.org> --- I just encountered this myself. And I can provide easier steps to reproduce. The bug was probably introduced by 7e68af7ce2c1b892954df415774fe59fd2f1b62f , which means that it does not affect 15.0-RELEASE, but will affect 15.1-RELEASE. However, it only affects INVARIANTS kernels, so the regular GENERIC 15.1-RELEASE kernel is unaffected. Steps to Reproduce ================== Attempt to execute any file stored on a fusefs file system, with INVARIANTS enabled in the kernel:. For example: $ sudo pkg install -y e2fsprogs-core fusefs-ext2 $ truncate -s 256m /tmp/ext2.img $ mkfs.ext2 /tmp/ext2.img $ sudo fuse-ext2 -o rw+ /tmp/ext2.img /mnt $ sudo mkdir /mnt/tmp $ chmod 1777 /mnt/tmp $ cp /usr/bin/true /mnt/tmp /usr/bin/true -- You are receiving this mail because: You are the assignee for the bug.home | help
