Package: attr Version: 1:2.5.1-4 Severity: normal Dear Maintainer,
I would like to inspect the value of the system.posix_acl_access xattr.
However, no matter which parameter I pass, I always get a forced prefix:
-- >8 --
# strace attr -g system.posix_acl_access install 2>&1 | grep xattr
lgetxattr("install", "user.system.posix_acl_access", 0x56c02c00, 65536) = -1
EOPNOTSUPP (Operation not supported)
lgetxattr("install", "user.system.posix_acl_access", 0x56c02c00, 65536) = -1
EOPNOTSUPP (Operation not supported)
# strace attr -Sg system.posix_acl_access install 2>&1 | grep xattr
lgetxattr("install", "security.system.posix_acl_access", 0x574f8c00, 65536) =
-1 ENODATA (No data available)
lgetxattr("install", "security.system.posix_acl_access", 0x574f8c00, 65536) =
-1 ENODATA (No data available)
# strace attr -Rg system.posix_acl_access install 2>&1 | grep xattr
lgetxattr("install", "trusted.system.posix_acl_access", 0x5832ac00, 65536) = -1
ENODATA (No data available)
lgetxattr("install", "xfsroot.system.posix_acl_access", 0x5832ac00, 65536) = -1
EOPNOTSUPP (Operation not supported)
-- >8 --
Whereas attr(1) says:
-- >8 --
When the -R option is given and the process has appropriate privileges,
operate in the root attribute namespace rather that the USER attribute
namespace.
The -S option is similar, except it specifies use of the security
attribute namespace.
-- >8 --
Which appears to be wrong, since -R makes attr
"operate in the 'trusted' and 'xfsroot'" namespaces,
not the root one.
Best,
