https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259071 --- Comment #16 from Alan Somers <asomers@FreeBSD.org> --- Update: I just reproduced the problem with sshfs, and the cause looks to be exactly the same as on NFS. It's a race between fuse_vnop_lookup and fuse_vnop_setattr. fuse_vnop_getattr, fuse_vnop_getpages, and fuse_vnop_bmap aren't vulnerable, because they have the vnode locked for the entire time. fuse_vfsop_vget, used by the NFS server, does look vulnerable. -- You are receiving this mail because: You are the assignee for the bug.help
