Some Gnucoreutils binaries uses posix acls, eg, install, ls, cp. And fails ifwe unexpectedly return EPERM error from xattr system calls.In the other hands, in Linux read and write access to the systemnamespace depend on the policy implemented for each filesystem, so we'llmimics we're a filesystem that prohibits this for unpriveleged accounts.Reported by: ziriasTested by: ziriasMFC after: 1 week(cherry picked from commit 11e37048db35d7fcfc285b867965de1aeefec2c8) List of files: /freebsd-14.2/sys/compat/linux/linux_xattr.c Tue, 05 Sep 2023 08:52:27 +0000 Dmitry Chagin <dchagin@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/sys/compat/linux/linux_xattr.c#53b3e15d linux(4): Fix listxattr for the case when the size is 0If size is specified as zero, these calls return the current sizeof the list of extended attribute names (and leave list unchanged).Tested by: ziriasMFC after: 1 week(cherry picked from commit 18d1c86788f66f42c4e096142f4f8d168f68732c) List of files: /freebsd-14.2/sys/compat/linux/linux_xattr.c Tue, 05 Sep 2023 08:51:46 +0000 Dmitry Chagin <dchagin@FreeBSD.org> http://172.16.0.5:8080/history/freebsd-14.2/sys/compat/linux/linux_xattr.c#bce9c2e3 linux(4): Return ENOTSUP from xattr syscalls instead of EPERMFreeBSD does not permits manipulating extended attributes in the systemnamespace by unprivileged accounts, even if account has appropriateprivileges to access filesystem object.In Linux the system namespace is used to preserve posix acls.
