https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D283965 --- Comment #1 from Alan Somers <asomers@FreeBSD.org> --- I've determined that the cause of the failure in nfscl_invalidfname is beca= use my test fuse file system includes the NUL character in its readdir entries.= =20 That is, it replies something like this: ents[0].d_namlen =3D 3; ents[0].d_name =3D ".."; ents[1].d_namlen =3D 2; ents[1].d_name =3D "."; I can and will fix that in the tests. But I can't guarantee that other fuse file systems won't do the same. Even if I have fusefs sanitize these strin= gs in-kernel, other file systems might do the same. For example, I see that e= xt2 trusts the on-disk data, and copies it into a dirent without sanitizing it.= So NFS must be able to handle that. --=20 You are receiving this mail because: You are the assignee for the bug.=
