* 9p: remove sysctlEric Van Hensbergen2007-10-173-92/+0
| | | | | | | | | | A sysctl method was added to enable and disable debugging levels. After further review, it was decided that there are better approaches to doing this and the sysctl methodology isn't really desirable. This patch removes the sysctl code from 9p.

* 9p: fix bad kconfig cross-dependencyEric Van Hensbergen2007-10-173-0/+64

* 9p: attach-per-userLatchesar Ionkov2007-10-172-8/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 9P2000 protocol requires the authentication and permission checks to be done in the file server. For that reason every user that accesses the file server tree has to authenticate and attach to the server separately. Multiple users can share the same connection to the server. Currently v9fs does a single attach and executes all I/O operations as a single user. This makes using v9fs in multiuser environment unsafe as it depends on the client doing the permission checking. This patch improves the 9P2000 support by allowing every user to attach separately. The patch defines three modes of access (new mount option 'access'): - attach-per-user (access=user) (default mode for 9P2000.u) If a user tries to access a file served by v9fs for the first time, v9fs sends an attach command to the server (Tattach) specifying the user. If the attach succeeds, the user can access the v9fs tree. As there is no uname->uid (string->integer) mapping yet, this mode works only with the 9P2000.u dialect. - allow only one user to access the tree (access=<uid>) Only the user with uid can access the v9fs tree. Other users that attempt to access it will get EPERM error. - do all operations as a single user (access=any) (default for 9P2000) V9fs does a single attach and all operations are done as a single user. If this mode is selected, the v9fs behavior is identical with the current one. Signed-off-by: Latchesar Ionkov <lucho@ionkov.net> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 9p: Make transports dynamicEric Van Hensbergen2007-10-175-159/+281

* r/o bind mounts: filesystem helpers for custom 'struct file'sDave Hansen2007-10-171-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Why do we need r/o bind mounts? This feature allows a read-only view into a read-write filesystem. In the process of doing that, it also provides infrastructure for keeping track of the number of writers to any given mount. This has a number of uses. It allows chroots to have parts of filesystems writable. It will be useful for containers in the future because users may have root inside a container, but should not be allowed to write to somefilesystems. This also replaces patches that vserver has had out of the tree for several years. It allows security enhancement by making sure that parts of your filesystem read-only (such as when you don't trust your FTP server), when you don't want to have entire new filesystems mounted, or when you want atime selectively updated. I've been using the following script to test that the feature is working as desired. It takes a directory and makes a regular bind and a r/o bind mount of it. It then performs some normal filesystem operations on the three directories, including ones that are expected to fail, like creating a file on the r/o mount. This patch: Some filesystems forego the vfs and may_open() and create their own 'struct file's. This patch creates a couple of helper functions which can be used by these filesystems, and will provide a unified place which the r/o bind mount code may patch. Also, rename an existing, static-scope init_file() to a less generic name.

* KEYS: Make request_key() and co fundamentally asynchronousDavid Howells2007-10-172-3/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make request_key() and co fundamentally asynchronous to make it easier for NFS to make use of them. There are now accessor functions that do asynchronous constructions, a wait function to wait for construction to complete, and a completion function for the key type to indicate completion of construction. Note that the construction queue is now gone. Instead, keys under construction are linked in to the appropriate keyring in advance, and that anyone encountering one must wait for it to be complete before they can use it. This is done automatically for userspace. The following auxiliary changes are also made: (1) Key type implementation stuff is split from linux/key.h into linux/key-type.h. (2) AF_RXRPC provides a way to allocate null rxrpc-type keys so that AFS does not need to call key_instantiate_and_link() directly. (3) Adjust the debugging macros so that they're -Wformat checked even if they are disabled, and make it so they can be enabled simply by defining __KDEBUG to be consistent with other code of mine.

* Remove "unsafe" from module structRusty Russell2007-10-171-1/+0
| | | | | | | | | | | | | | | | | | | | Adrian Bunk points out that "unsafe" was used to mark modules touched by the deprecated MOD_INC_USE_COUNT interface, which has long gone. It's time to remove the member from the module structure, as well. If you want a module which can't unload, don't register an exit function. (Vlad Yasevich says SCTP is now safe to unload, so just remove the __unsafe there).

However, the "creation" code does not perform the re-lookup after GFP_KERNEL allocation.

The only place when it made sense was the evictor code itself. Maybe this change must got with the previous (or with the next) patch, but I try to make them shorter as much as possible to simplify the review (but they are still large anyway), so this change goes in a separate patch.

Like with the previous patch this mostly consists of hunks like - write_lock(&ipfrag_lock); + write_lock(&ip4_frags.lock); To address the issue with exporting the number of queues and the amount of memory occupied by queues outside the .c file they are declared in, I introduce a couple of helpers.

* [NET]: Avoid copying TCP packets unnecessarilyHerbert Xu2007-10-151-11/+10
| | | | | | | | | | | | | | | TCP packets all have writable heads, that is, even though it's cloned, it is writable up to the end of the TCP header. This patch makes skb_checksum_help aware of this fact by using skb_clone_writable and avoiding a copy for TCP. I've also modified the BUG_ON tests to be unsigned. The only case where this makes a difference is if csum_start points to a location before skb->data. Since skb->data should always include the header where the checksum field is (and all currently callers adhere to that), this change is safe and may uncover bugs later.

| | | | | | | | | | | | | | It completely fouls up the RPC call statistics, and serves no useful purpose. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | Use correct type signage in gss_krb5_remove_padding() when doing length calculations. Both xdr_buf.len and iov.iov_len are size_t, which is unsigned; so use an unsigned type for our temporary length variable to ensure we don't overflow it..

| * SUNRPC: Fix default hostname created in rpc_create()J. Bruce Fields2007-10-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 43780b87fa7..., rpc_create() fills in a default hostname based on the ip address if the servername passed in is null. A small typo made that default incorrect. (But this information appears to be used only for debugging right now, so I don't believe the typo causes any bugs in the current kernel.)

| * nfs: add server port to rpc_pipe info fileJ. Bruce Fields2007-10-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the client, when an alternate server port is specified on the mount commandline, we need to make sure gssd knows about it. Also, on the server side, when we're sending krb5 callbacks to the client, we'll use the same mechanism to let gssd know about the callback port.
