* l2tp: Update documentationJames Chapman2010-04-03
| | | | | | | | This patch adds documentation about the L2TPv3 functionality. Signed-off-by: James Chapman <jchapman@katalix.com> Reviewed-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* l2tp: Add support for static unmanaged L2TPv3 tunnelsJames Chapman2010-04-03
| | | | | | | | | | | | | | | | This patch adds support for static (unmanaged) L2TPv3 tunnels, where the tunnel socket is created by the kernel rather than being created by userspace. This means L2TP tunnels and sessions can be created manually, without needing an L2TP control protocol implemented in userspace. This might be useful where the user wants a simple ethernet over IP tunnel. A patch to iproute2 adds a new command set under "ip l2tp" to make use of this feature. This will be submitted separately.

* l2tp: Add debugfs files for dumping l2tp debug infoJames Chapman2010-04-03
| | | | | | | | | | | | | | | | | | | | The existing pppol2tp driver exports debug info to /proc/net/pppol2tp. Rather than adding info to that file for the new functionality added in this patch series, we add new files in debugfs, leaving the old /proc file for backwards compatibility (L2TPv2 only). Currently only one file is provided: l2tp/tunnels, which lists internal debug info for all l2tp tunnels and sessions. More files may be added later. The info is for debug and problem analysis only - userspace apps should use netlink to obtain status about l2tp tunnels and sessions. Although debugfs does not support net namespaces, the tunnels and sessions dumped in l2tp/tunnels are only those in the net namespace of the process reading the file.

* l2tp: Add L2TP ethernet pseudowire supportJames Chapman2010-04-03
| | | | | | | | | | | | | | This driver presents a regular net_device for each L2TP ethernet pseudowire instance. These interfaces are named l2tpethN by default, though userspace can specify an alternative name when the L2TP session is created, if preferred. When the pseudowire is established, regular Linux networking utilities may be used to configure the interface, i.e. give it IP address info or add it to a bridge. Any data passed over the interface is carried over an L2TP tunnel. Signed-off-by: James Chapman <jchapman@katalix.com> Reviewed-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: David S.

* l2tp: Add netlink control API for L2TPJames Chapman2010-04-03
| | | | | | | | | | | | | | | | | | | In L2TPv3, we need to create/delete/modify/query L2TP tunnel and session contexts. The number of parameters is significant. So let's use netlink. Userspace uses this API to control L2TP tunnel/session contexts in the kernel. The previous pppol2tp driver was managed using [gs]etsockopt(). This API is retained for backwards compatibility. Unlike L2TPv2 which carries only PPP frames, L2TPv3 can carry raw ethernet frames or other frame types and these do not always have an associated socket family. Therefore, we need a way to use L2TP sessions that doesn't require a socket type for each supported frame type. Hence netlink is used.

* l2tp: Add L2TPv3 IP encapsulation (no UDP) supportJames Chapman2010-04-03
| | | | | | | | | | | | | | This patch adds a new L2TPIP socket family and modifies the core to handle the case where there is no UDP header in the L2TP packet. L2TP/IP uses IP protocol 115. Since L2TP/UDP and L2TP/IP packets differ in layout, the datapath packet handling code needs changes too. Userspace uses an L2TPIP socket instead of a UDP socket when IP encapsulation is required. We can't use raw sockets for this because the semantics of raw sockets don't lend themselves to the socket-per-tunnel model - we need to Signed-off-by: David S. Miller <davem@davemloft.net>
* l2tp: Update PPP-over-L2TP driver to work over L2TPv3James Chapman2010-04-03
| | | | | | | | | | | | | | | This patch makes changes to the L2TP PPP code for L2TPv3. The existing code has some assumptions about the L2TP header which are broken by L2TPv3. Also the sockaddr_pppol2tp structure of the original code is too small to support the increased size of the L2TPv3 tunnel and session id, so a new sockaddr_pppol2tpv3 structure is needed. In the socket calls, the size of this structure is used to tell if the operation is for L2TPv2 or L2TPv3.

* l2tp: Add L2TPv3 protocol supportJames Chapman2010-04-03
| | | | | | | | | | | | | | The L2TPv3 protocol changes the layout of the L2TP packet header. Tunnel and session ids change from 16-bit to 32-bit values, data sequence numbers change from 16-bit to 24-bit values and PPP-specific fields are moved into protocol-specific subheaders. Although this patch introduces L2TPv3 protocol support, there are no userspace interfaces to create L2TPv3 sessions yet.

* l2tp: Split pppol2tp patch into separate l2tp and ppp partsJames Chapman2010-04-03
| | | | | | | | | | | | | | | | | | | | This patch splits the pppol2tp driver into separate L2TP and PPP parts to prepare for L2TPv3 support. In L2TPv3, protocols other than PPP can be carried, so this split creates a common L2TP core that will handle the common L2TP bits which protocol support modules such as PPP will use. Note that the existing pppol2tp module is split into l2tp_core and l2tp_ppp by this change. There are no feature changes here. Internally, however, there are significant changes, mostly to handle the separation of PPP-specific data from the L2TP session and to provide hooks in the core for modules like PPP to access.

The existing CONFIG_PPPOL2TP config option is left in its current place to avoid "make oldconfig" issues when an existing pppol2tp user takes this change. (This is the same approach used for the pppoatm driver, which moved to net/atm.) There are no code changes. The existing drivers/net/pppol2tp.c is simply moved to net/l2tp.

* net: change illegal_highdma to use dma_maskFUJITA Tomonori2010-04-01
| | | | | | | | | | | | | | | | | | | | | | Robert Hancock pointed out two problems about NETIF_F_HIGHDMA: -Many drivers only set the flag when they detect they can use 64-bit DMA, since otherwise they could receive DMA addresses that they can't handle (which on platforms without IOMMU/SWIOTLB support is fatal). This means that if 64-bit support isn't available, even buffers located below 4GB will get copied unnecessarily. -Some drivers set the flag even though they can't actually handle 64-bit DMA, which would mean that on platforms without IOMMU/SWIOTLB they would get a DMA mapping error if the memory they received happened to be located above 4GB. http://lkml.org/lkml/2010/3/3/530 We can use the dma_mask if we need bouncing or not here.

* xfrm: remove policy lock when accessing policy->walk.deadTimo Teräs2010-04-01
| | | | | | | | | | | | | | | | | | | | | All of the code considers ->dead as a hint that the cached policy needs to get refreshed. The read side can just drop the read lock without any side effects. The write side needs to make sure that it's written only exactly once. Only possible race is at xfrm_policy_kill(). This is fixed by checking result of __xfrm_policy_unlink() when needed. It will always succeed if the policy object is looked up from the hash list (so some checks are removed), but it needs to be checked if we are trying to unlink policy via a reference (appropriate checks added). Since policy->walk.dead is written exactly once, it no longer needs to be protected with a write lock.

On 64bit, sizeof(struct Qdisc) is exactly 192 bytes. Adding 16 bytes to it (for struct rcu_head) is a problem because it might change performance, given QDISC_ALIGNTO is 32 bytes.
