...and fix up the callers. For do_file_open_root, just declare a struct filename on the stack and fill out the .name field. For do_filp_open, make it also take a struct filename pointer, and fix up its callers to call it appropriately. For filp_open, add a variant that takes a struct filename pointer and turn filp_open into a wrapper around it.

Currently, if we call getname() on a userland string more than once, we'll get multiple copies of the string and multiple audit_names records. Add a function that will allow the audit_names code to satisfy getname requests using info from the audit_names list, avoiding a new allocation and audit_names records.

getname() is intended to copy pathname strings from userspace into a kernel buffer. The result is just a string in kernel space. It would however be quite helpful to be able to attach some ancillary info to the string. For instance, we could attach some audit-related info to reduce the amount of audit-related processing needed. When auditing is enabled, we could also call getname() on the string more than once and not need to recopy it from userspace. This patchset converts the getname()/putname() interfaces to return a struct instead of a string. For now, the struct just tracks the string in kernel space and the original userland pointer for it. Later, we'll add other information to the struct as it becomes convenient. Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

First, it's incorrect to call putname() after __getname_gfp() since the bare __getname_gfp() call skips the auditing code, while putname() doesn't. mount_block_root allocates a PATH_MAX buffer via __getname_gfp, and then calls get_fs_names to fill the buffer. That function can call get_filesystem_list which assumes that that buffer is a full page in size. On arches where PAGE_SIZE != 4k, then this could potentially overrun. In practice, it's hard to imagine the list of filesystem names even approaching 4k, but it's best to be safe. Just allocate a page for this purpose instead. With this, we can also remove the __getname_gfp() definition since there are no more callers. Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

In order to accomodate retrying path-based syscalls, we need to add a new "type" argument to audit_inode_child. This will tell us whether we're looking for a child entry that represents a create or a delete. If we find a parent, don't automatically assume that we need to create a new entry. Instead, use the information we have to try to find an existing entry first. Update it if one is found and create a new one if not.

Currently, this gets set mostly by happenstance when we call into audit_inode_child. While that might be a little more efficient, it seems wrong. If the syscall ends up failing before audit_inode_child ever gets called, then you'll have an audit_names record that shows the full path but has the parent inode info attached. Fix this by passing in a parent flag when we call audit_inode that gets set to the value of LOOKUP_PARENT. We can then fix up the pathname for the audit entry correctly from the get-go. While we're at it, clean up the no-op macro for audit_inode in the !CONFIG_AUDITSYSCALL case. Signed-off-by: NJeff Layton <jlayton@redhat.com> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

Most of the callers get called with an inode and dentry in the reverse order. The compiler then has to reshuffle the arg registers and/or stack in order to pass them on to audit_inode_child.

The follow_link() function always initializes its *p argument, or returns an error, but when building with 'gcc -s', the compiler gets confused by the __always_inline attribute to the function and can no longer detect where the cookie was initialized. The solution is to always initialize the pointer from follow_link, even in the error path. When building with -O2, this has zero impact on generated code and adds a single instruction in the error path for a -Os build on ARM. Without this patch, building with gcc-4.6 through gcc-4.8 and CONFIG_CC_OPTIMIZE_FOR_SIZE results in: fs/namei.c: In function 'link_path_walk': fs/namei.c:649:24: warning: 'cookie' may be used uninitialized in this function [-Wuninitialized] fs/namei.c:1544:9: note: 'cookie' was declared here fs/namei.c: In function 'path_lookupat': fs/namei.c:649:24: warning: 'cookie' may be used uninitialized in this function [-Wuninitialized] fs/namei.c:1934:10: note: 'cookie' was declared here fs/namei.c: In function 'path_openat': fs/namei.c:649:24: warning: 'cookie' may be used uninitialized in this function [-Wuninitialized] fs/namei.c:2899:9: note: 'cookie' was declared here Signed-off-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>
