With 11.2 listxattr returns -ENODATA in the second case. On linux output of strace of listxattr of directory ./nano without extended attributes: listxattr(".nano/", NULL, 0) =3D 0 On FreeBSD output of ktrace of listxattr of directory without extended attributes: 54332 dsmc RET linux_llistxattr -1 errno -61 Attribute not found Following change in code between 11.1 and 11.2 led to the emergence of the = bug. In 11.1 EOPNOTSUPP was returned instead of ENODATA. This change may seem correct for other linux xattr calls, but not for listxattr. *** linux32_sysvec.c Mon Jan 7 18:30:21 2019 --- linux32_sysvec.c-11.2 Fri Jun 22 01:02:23 2018 *************** *** 146,152 **** -100,-101,-102,-103,-104,-105,-106,-107,-108,-109, -110,-111, -40, -36,-112,-113, -39, -11, -87,-122, -116, -66, -6, -6, -6, -6, -6, -37, -38, -9, ! -6, -6, -43, -42, -75,-125, -84, -95, -16, -74, -72, -67, -71 }; --- 146,152 ---- -100,-101,-102,-103,-104,-105,-106,-107,-108,-109, -110,-111, -40, -36,-112,-113, -39, -11, -87,-122, -116, -66, -6, -6, -6, -6, -6, -37, -38, -9, ! -6, -6, -43, -42, -75,-125, -84, -61, -16, -74, -72, -67, -71 }; --=20 You are receiving this mail because: You are the assignee for the bug.=
