2007-11-08[CIFS] Fix stale mode after readdir when cifsacl specifiedSteve French
When mounted with cifsacl mount option, readdir can not instantiate the inode with the estimated mode based on the ACL for each file since we have not queried for the ACL for each of these files yet. So set the refresh time to zero for these inodes so that the next stat will cause the client to go to the server for the ACL info so we can build the estimated mode (this means we also will issue an extra QueryPathInfo if the stat happens within 1 second, but this is trivial compared to the time required to open/getacl/close for each). ls -l is slower when cifsacl mount option is specified, but displays correct mode information.

2007-11-08[CIFS] Fix incorrect mode when ACL had deny access control entriesSteve French
When mounted with the cifsacl mount option, we were treating any deny ACEs found like allow ACEs and it turns out for SFU and SUA Windows set these type of access control entries often. The order of ACEs is important too. The canonical order that most ACL tools and Windows explorer consruct ACLs with is to begin with DENY entries then follow with ALLOW, otherwise an allow entry could be encountered first, making the subsequent deny entry like "dead code which would be superflous since Windows stops when a match is made for the operation you are trying to perform for your user We start with no permissions in the mode and build up as we find permissions (ie allow ACEs). This fixes deny ACEs so they affect the mask used to set the subsequent allow ACEs.

2007-11-01[CIFS] when mount helper missing fix slash wrong direction in shareSteve French
Kernel bugzilla bug #9228 If mount helper (mount.cifs) missing, mounts with form like //10.11.12.13/c$ would not work (only mounts with slash e.g. //10.11.12.13\\c$ would work) due to problem with slash supposed to be converted to backslash by the mount helper (which is not there). If we fail on converting an IPv4 address in in4_pton then try to canonicalize the first slash (ie between sharename and host ip address) if necessary. If we have to retry to check for IPv6 address the slash is already converted if necessary. Signed-off-by: Steve French <sfrench@us.ibm.com>

2007-10-21[PATCH] audit: watching subtreesAl Viro
New kind of audit rule predicates: "object is visible in given subtree". The part that can be sanely implemented, that is. Limitations: * if you have hardlink from outside of tree, you'd better watch it too (or just watch the object itself, obviously) * if you mount something under a watched tree, tell audit that new chunk should be added to watched subtrees * if you umount something in a watched tree and it's still mounted elsewhere, you will get matches on events happening there. New command tells audit to recalculate the trees, trimming such sources of false positives. Note that it's _not_ about path - if something mounted in several places (multiple mount, bindings, different namespaces, etc.), the match does _not_ depend on which one we are using for access.

2007-10-19NFS: Fix a race in sillyrenameTrond Myklebust
lookup() and sillyrename() can race one another because the sillyrename() completion cannot take the parent directory's inode->i_mutex since the latter may be held by whoever is calling dput(). We therefore have little option but to add extra locking to ensure that nfs_lookup() and nfs_atomic_open() do not race with the sillyrename completion. If somebody has looked up the sillyrenamed file in the meantime, we just transfer the sillydelete information to the new dentry.

This patch fixes a regression that was introduced by commit 44dd151d5c21234cc534c47d7382f5c28c3143cd We cannot zero the user page in nfs_mark_uptodate() any more, since a) We'd be modifying the page without holding the page lock b) We can race with other updates of the page, most notably because of the call to nfs_wb_page() in nfs_writepage_setup(). Instead, we do the zeroing in nfs_update_request() if we see that we're creating a request that might potentially be marked as up to date.
