* [IPSEC]: Move type and mode map into xfrm_state.cHerbert Xu2007-10-182-173/+170
| | | | | | | | | | | | | | The type and mode maps are only used by SAs, not policies. So it makes sense to move them from xfrm_policy.c into xfrm_state.c. This also allows us to mark xfrm_get_type/xfrm_put_type/xfrm_get_mode/xfrm_put_mode as static. The only other change I've made in the move is to get rid of the casts on the request_module call for types. They're unnecessary because C will promote them to ints anyway.

* [IPSEC]: Fix length check in xfrm_parse_spiHerbert Xu2007-10-181-1/+4
| | | | | | | | | | | Currently xfrm_parse_spi requires there to be 16 bytes for AH and ESP. In contrived cases there may not actually be 16 bytes there since the respective header sizes are less than that (8 and 12 currently). This patch changes the test to use the actual header length instead of 16. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPSEC]: Move ip_summed zapping out of xfrm6_rcv_spiHerbert Xu2007-10-182-1/+2
| | | | | | | | | | | | | | Not every transform needs to zap ip_summed. For example, a pure tunnel mode encapsulation does not affect the hardware checksum at all. In fact, every algorithm (that needs this) other than AH6 already does its own ip_summed zapping. This patch moves the zapping into AH6 which is in line with what IPv4 does. Possible future optimisation: Checksum the data as we copy them in IPComp. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPSEC]: Get nexthdr from caller in xfrm6_rcv_spiHerbert Xu2007-10-182-6/+5
| | | | | | | | | | Currently xfrm6_rcv_spi gets the nexthdr value itself from the packet. This means that we need to fix up the value in case we have a 4-on-6 tunnel. Moving this logic into the caller simplifies things and allows us to merge the code with IPv4. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* [IPSEC]: Fix pure tunnel modes involving IPv6Herbert Xu2007-10-182-2/+2
| | | | | | | | | | | | | I noticed that my recent patch broke 6-on-4 pure IPsec tunnels (the ones that are only used for incompressible IPsec packets). Subsequent reviews show that I broke 6-on-6 pure tunnels more than three years ago and nobody ever noticed. I suppose every must be testing 6-on-6 IPComp with large pings which are very compressible :) This patch fixes both cases.

* [NET]: Fix the race between sk_filter_(de|at)tach and sk_clone()Pavel Emelyanov2007-10-181-2/+21
| | | | | | | | | | | | | The proposed fix is to delay the reference counter decrement until the quiescent state pass. This will give sk_clone() a chance to get the reference on the cloned filter. Regular sk_filter_uncharge can happen from the sk_free() only and there's no need in delaying the put - the socket is dead anyway and is to be release itself.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here we need another callback ->match to check whether the entry found in hash matches the key passed. The key used is the same as the creation argument for inet_frag_create. Yet again, this ->match is the same for netfilter and ipv6. Running a frew steps forward - this callback will later replace the ->equal one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just perform the kzalloc() allocation and setup common fields in the inet_frag_queue(). Then return the result to the caller to initialize the rest. The inet_frag_alloc() may return NULL, so check the return value before doing the container_of(). This looks ugly, but the xxx_frag_alloc() will be removed soon. The xxx_expire() timer callbacks are patches, because the argument is now the inet_frag_queue, not the protocol specific queue.

The ->equal callback is used to compare two frag_queue-s together, but this one is temporary and will be removed later. The netfilter code and the ipv6 one use the same routine to compare frags. The inet_frag_intern() always returns non-NULL pointer, so convert the inet_frag_queue into protocol specific one (with the container_of) without any checks.

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>

* | 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.

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.

* [INET]: Small cleanup for xxx_put after evictor consolidationPavel Emelyanov2007-10-153-16/+16
| | | | | | | | | | | | | | | After the evictor code is consolidated there is no need in passing the extra pointer to the xxx_put() functions. 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.

* [INET]: Consolidate the xxx_evictorPavel Emelyanov2007-10-154-80/+41
| | | | | | | | | | | | | The evictors collect some statistics for ipv4 and ipv6, so make it return the number of evicted queues and account them all at once in the caller. The XXX_ADD_STATS_BH() macros are just for this case, but maybe there are places in code, that can make use of them as well. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

* [INET]: Consolidate the xxx_frag_destroyPavel Emelyanov2007-10-154-86/+69
| | | | | | | | | | | | | | To make in possible we need to know the exact frag queue size for inet_frags->mem management and two callbacks: * to destoy the skb (optional, used in conntracks only) * to free the queue itself (mandatory, but later I plan to move the allocation and the destruction of frag_queues into the common place, so this callback will most likely be optional too).

* [INET]: Consolidate xxx_the secret_rebuildPavel Emelyanov2007-10-154-90/+50
| | | | | | | | | | | | | | | This code works with the generic data types as well, so move this into inet_fragment.c This move makes it possible to hide the secret_timer management and the secret_rebuild routine completely in the inet_fragment.c Introduce the ->hashfn() callback in inet_frags() to get the hashfun for a given inet_frag_queue() object.

* [INET]: Consolidate the xxx_frag_killPavel Emelyanov2007-10-154-66/+26
| | | | | | | | | | | Since now all the xxx_frag_kill functions now work with the generic inet_frag_queue data type, this can be moved into a common place. The xxx_unlink() code is moved as well. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
