* xattr handlers: Pass handler to operations instead of flagsAndreas Gruenbacher2015-11-131-15/+13
| | | | | | | | | | | | | The xattr_handler operations are currently all passed a file system specific flags value which the operations can use to disambiguate between different handlers; some file systems use that to distinguish the xattr namespace, for example. In some oprations, it would be useful to also have access to the handler prefix. To allow that, pass a pointer to the handler to operations instead of the flags value alone.

* vfs: Fix the posix_acl_xattr_list return valueAndreas Gruenbacher2015-11-131-3/+1
| | | | | | | | | | | | | | When a filesystem that contains POSIX ACLs is mounted without ACL support (-o noacl), the appropriate behavior is not to list any existing POSIX ACL xattrs. The return value for list xattr handlers in this case is 0, not an error code: several filesystems that use the POSIX ACL xattr handlers do not expect the list operation to fail. Symlinks cannot have ACLs, so posix_acl_xattr_list will never be called for symlinks in the first place.

| | | | | | | | | | The get and set operations of the POSIX ACL xattr handlers failed to check the attribute names, so all names with "system.posix_acl_access" or "system.posix_acl_default" as a prefix were accepted.

* fs/posix_acl.c: make posix_acl_create() safer and cleanerDan Carpenter2015-06-231-26/+20
| | | | | | | | | | | | | | | | | | | | | If posix_acl_create() returns an error code then "*acl" and "*default_acl" can be uninitialized or point to freed memory. This is a dangerous thing to do. For example, it causes a problem in ocfs2_reflink(): fs/ocfs2/refcounttree.c:4327 ocfs2_reflink() error: potentially using uninitialized 'default_acl'. I've re-written this so we set the pointers to NULL at the start. I've added a temporary "clone" variable to hold the value of "*acl" until end. Setting them to NULL means means we don't need the "no_acl" label. We may as well remove the "apply_umask" stuff forward and remove that label as well.

* VFS: (Scripted) Convert S_ISLNK/DIR/REG(dentry->d_inode) to d_is_*(dentry)David Howells2015-02-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert the following where appropriate: (1) S_ISLNK(dentry->d_inode) to d_is_symlink(dentry). (2) S_ISREG(dentry->d_inode) to d_is_reg(dentry). (3) S_ISDIR(dentry->d_inode) to d_is_dir(dentry). This is actually more complicated than it appears as some calls should be converted to d_can_lookup() instead. The difference is whether the directory in question is a real dir with a ->lookup op or whether it's a fake dir with a ->d_automount op. In some circumstances, we can subsume checks for dentry->d_inode not being NULL into this, provided we the code isn't in a filesystem that expects d_inode to be NULL if the dirent really *is* negative (ie. if we're going to use d_inode() rather than d_backing_inode() to get the inode pointer). Note that the dentry type field may be set to something other than DCACHE_MISS_TYPE when d_inode is NULL in the case of unionmount, where the VFS manages the fall-through from a negative dentry to a lower layer. In such a case, the dentry type of the negative union dentry is set to the same as the type of the lower dentry. However, if you know d_inode is not NULL at the call site, then you can use the d_is_xxx() functions even in a filesystem. There is one further complication: a 0,0 chardev dentry may be labelled DCACHE_WHITEOUT_TYPE rather than DCACHE_SPECIAL_TYPE. Strictly, this was intended for special directory entry types that don't have attached inodes. The following perl+coccinelle script was used: use strict; my @callers; open($fd, 'git grep -l \'S_IS[A-Z].*->d_inode\' |') || die "Can't grep for S_ISDIR and co. callers"; @callers = <$fd>; close($fd); unless (@callers) { print "No matches\n"; exit(0); } my @cocci = ( '@@', 'expression E;', '@@', '', '- S_ISLNK(E->d_inode->i_mode)', '+ d_is_symlink(E)', '', '@@', 'expression E;', '@@', '', '- S_ISDIR(E->d_inode->i_mode)', '+ d_is_dir(E)', '', '@@', 'expression E;', '@@', '', '- S_ISREG(E->d_inode->i_mode)', '+ d_is_reg(E)' ); my $coccifile = "tmp.sp.cocci"; open($fd, ">$coccifile") || die $coccifile; print($fd "$_\n") || die $coccifile foreach (@cocci); close($fd); foreach my $file (@callers) { chomp $file; print "Processing ", $file, "\n"; system("spatch", "--sp-file", $coccifile, $file, "--in-place", "--no-show-diff") == 0 || die "spatch failed"; } [AV: overlayfs parts skipped] Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* posix_acl: handle NULL ACL in posix_acl_equiv_modeChristoph Hellwig2014-05-061-0/+6
| | | | | | | | | | | | | | | | | | Various filesystems don't bother checking for a NULL ACL in posix_acl_equiv_mode, and thus can dereference a NULL pointer when it gets passed one. This usually happens from the NFS server, as the ACL tools never pass a NULL ACL, but instead of one representing the mode bits. Instead of adding boilerplat to all filesystems put this check into one place, which will allow us to remove the check from other filesystems as well later on.

It is good to see that interest is increasing in GFS2, and I'd like to thank all the contributors to this patch set. In addition to the usual set of bug fixes and clean ups, there are patches to improve inode creation performance when xattrs are required and some improvements to the transaction code which is intended to help improve scalability after further changes in due course. Journal extent mapping is also updated to make it more efficient and again, this is a foundation for future work in this area. The maximum number of ACLs has been increased to 300 (for a 4k block size) which means that even with a few additional xattrs from selinux, everything should fit within a single fs block. There is also a patch to bring GFS2's own copy of the writepages code up to the same level as the core VFS. Eventually we may be able to merge some of this code, since it is fairly similar.

* | userns: relax the posix_acl_valid() checksAndreas Gruenbacher2014-01-231-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, POSIX ACLs are using a canonical representation that keeps all ACL entries in a strict order; the ACL_USER and ACL_GROUP entries for specific users and groups are ordered by user and group identifier, respectively. The user-space code provides ACL entries in this order; the kernel verifies that the ACL entry order is correct in posix_acl_valid(). User namespaces allow to arbitrary map user and group identifiers which can cause the ACL_USER and ACL_GROUP entry order to differ between user space and the kernel; posix_acl_valid() would then fail. Work around this by allowing ACL_USER and ACL_GROUP entries to be in any order in the kernel. The effect is only minor: file permission checks will pick the first matching ACL_USER entry, and check all matching ACL_GROUP entries. (The libacl user-space library and getfacl / setfacl tools will not create ACLs with duplicate user or group idenfifiers; they will handle ACLs with entries in an arbitrary order correctly.)

* userns: Convert vfs posix_acl support to use kuids and kgidsEric W. Biederman2012-09-181-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - In setxattr if we are setting a posix acl convert uids and gids from the current user namespace into the initial user namespace, before the xattrs are passed to the underlying filesystem. Untranslatable uids and gids are represented as -1 which posix_acl_from_xattr will represent as INVALID_UID or INVALID_GID. posix_acl_valid will fail if an acl from userspace has any INVALID_UID or INVALID_GID values. In net this guarantees that untranslatable posix acls will not be stored by filesystems. - In getxattr if we are reading a posix acl convert uids and gids from the initial user namespace into the current user namespace. Uids and gids that can not be tranlsated into the current user namespace will be represented as -1. - Replace e_id in struct posix_acl_entry with an anymouns union of e_uid and e_gid. For the short term retain the e_id field until all of the users are converted. - Don't set struct posix_acl.e_id in the cases where the acl type does not use e_id. Greatly reducing the use of ACL_UNDEFINED_ID. - Rework the ordering checks in posix_acl_valid so that I use kuid_t and kgid_t types throughout the code, and so that I don't need arithmetic on uid and gid types.

Since commit 9f06c719 "SUNRPC: New xdr_streams XDR encoder API", the kernel's XDR encoders can't return a result indicating possibly a failure, so a memory allocation failure in nfsacl_encode() has become fatal (ie, the XDR code Oopses) in some cases. However, the allocated memory is a tiny fixed amount, on the order of 40-50 bytes. We can easily use a stack-allocated buffer for this, with only a wee bit of nose-holding.
