This patch allows LSM modules to determine based on original mount flags passed to mount(). A LSM module can get masked mount flags (if needed) by flags &= ~(MS_NOSUID | MS_NOEXEC | MS_NODEV | MS_ACTIVE | MS_NOATIME | MS_NODIRATIME | MS_RELATIME| MS_KERNMOUNT | MS_STRICTATIME); Signed-off-by: Tetsuo Handa --- fs/namespace.c | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) --- security-testing-2.6.orig/fs/namespace.c +++ security-testing-2.6/fs/namespace.c @@ -1921,6 +1921,16 @@ long do_mount(char *dev_name, char *dir_ if (data_page) ((char *)data_page)[PAGE_SIZE - 1] = 0; + /* ... and get the mountpoint */ + retval = kern_path(dir_name, LOOKUP_FOLLOW, &path); + if (retval) + return retval; + + retval = security_sb_mount(dev_name, &path, + type_page, flags, data_page); + if (retval) + goto dput_out; + /* Default to relatime unless overriden */ if (!(flags & MS_NOATIME)) mnt_flags |= MNT_RELATIME; @@ -1945,16 +1955,6 @@ long do_mount(char *dev_name, char *dir_ MS_NOATIME | MS_NODIRATIME | MS_RELATIME| MS_KERNMOUNT | MS_STRICTATIME); - /* ... and get the mountpoint */ - retval = kern_path(dir_name, LOOKUP_FOLLOW, &path); - if (retval) - return retval; - - retval = security_sb_mount(dev_name, &path, - type_page, flags, data_page); - if (retval) - goto dput_out; - if (flags & MS_REMOUNT) retval = do_remount(&path, flags & ~MS_REMOUNT, mnt_flags, data_page); -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
