* userns: Disassociate user_struct from the user_namespace.Eric W. Biederman2012-04-071-4/+14
| | | | | | | | | | | Modify alloc_uid to take a kuid and make the user hash table global. Stop holding a reference to the user namespace in struct user_struct. This simplifies the code and makes the per user accounting not care about which user namespace a uid happens to appear in. Acked-by: Serge Hallyn <serge.hallyn@canonical.com> Signed-off-by: Eric W.

* userns: Replace the hard to write inode_userns with inode_capable.Eric W. Biederman2012-04-072-17/+7
| | | | | | | | | | | | | | | | | | | | | This represents a change in strategy of how to handle user namespaces. Instead of tagging everything explicitly with a user namespace and bulking up all of the comparisons of uids and gids in the kernel, all uids and gids in use will have a mapping to a flat kuid and kgid spaces respectively. This allows much more of the existing logic to be preserved and in general allows for faster code. In this new and improved world we allow someone to utiliize capabilities over an inode if the inodes owner mapps into the capabilities holders user namespace and the user has capabilities in their user namespace. Which is simple and efficient. Moving the fs uid comparisons to be comparisons in a flat kuid space follows in later patches, something that is only significant if you are using user namespaces.

* userns: Use cred->user_ns instead of cred->user->user_nsEric W. Biederman2012-04-071-1/+1
| | | | | | | | | Optimize performance and prepare for the removal of the user_ns reference from user_struct. Remove the slow long walk through cred->user->user_ns and instead go straight to cred->user_ns. Acked-by: Serge Hallyn <serge.hallyn@canonical.com> Signed-off-by: Eric W.

This is not normal behavior for a filesystem however. Usually, it should only do this if you mount with '-s', and autofs generally passes -s to the mount command to allow this behavior. This patch makes cifs handle the option "sloppy" appropriately. If it's present in the options string, then the client will tolerate options that it doesn't recognize. If it's not present then the client will error out in the presence of options that it does not recognize and throw an error message explaining why. There is also a companion patch being proposed for mount.cifs to make it append "sloppy" to the mount options when passed the '-s' flag. This also should (obviously) be applied on top of Sachin's conversion to the standard option parser. Signed-off-by: Jeff Layton <jlayton@redhat.com> Acked-By: Sachin Prabhu <sprabhu@redhat.com>

Aliases for username, password, domain and credentials have been added. The password parser has been modified to make it easier to read. Since the patch was first proposed, the following bugs have been fixed 1) Allow blank 'pass' option to be passed by the cifs mount helper when using sec=none. 2) Do not explicitly set vol->nullauth to 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cifs_update_eof has the potential to be racy if multiple threads are trying to modify it at the same time. Protect modifications of the server_eof value with the inode->i_lock. Signed-off-by: Jeff Layton <jlayton@redhat.com>
| | * | | cifs: abstract out function to marshal up the iovec array for async writesJeff Layton2012-03-233-10/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We'll need to do something a bit different depending on the caller. Abstract the code that marshals the page array into an iovec. Signed-off-by: Jeff Layton <jlayton@redhat.com> Reviewed-by: Pavel Shilovsky <piastry@etersoft.ru>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use DIV_ROUND_UP. Also, PAGE_SIZE is more appropriate here since these aren't pagecache pages. Signed-off-by: Jeff Layton <jlayton@redhat.com> Reviewed-by: Pavel Shilovsky <piastry@etersoft.ru>
