* Phonet: provide pipe socket option to retrieve the pipe identifierRémi Denis-Courmont2011-03-093-12/+12
| | | | | | | | | | | | | | User-space sometimes needs this information. In particular, the GPRS context or the AT commands pipe setups may use the pipe handle as a reference. This removes the settable pipe handle with CONFIG_PHONET_PIPECTRLR. It did not handle error cases correctly. Furthermore, the kernel *could* implement a smart scheme for allocating handles (if ever needed), but userspace really cannot.

* Phonet: allocate sock from accept syscall rather than soft IRQRémi Denis-Courmont2011-03-093-174/+121
| | | | | | | | | This moves most of the accept logic to process context like other socket stacks do. Then we can use a few more common socket helpers and simplify a bit. Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* Phonet: factor common code to send control messagesRémi Denis-Courmont2011-03-091-152/+73
| | | | | | | | With the addition of the pipe controller, there is now quite a bit of repetitive code for small signaling messages. Lets factor it. Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* Phonet: correct pipe backlog callback return valuesRémi Denis-Courmont2011-03-091-14/+11
| | | | | | | | | | | | In some cases, the Phonet pipe backlog callbacks returned negative errno instead of NET_RX_* values. In other cases, NET_RX_DROP was returned for invalid packets, even though it seems only intended for buffering problems (not for deliberately discarded packets).

* Phonet: return an error when packet TX failsRémi Denis-Courmont2011-03-091-5/+3
| | | | | | | | | Phonet assumes that packets are never dropped. We try our best to avoid this situation. But lets return ENOBUFS if queueing to the network device fails so that the caller knows things went wrong. Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S.

* Phonet: fix NULL dereference on TX path with implicit sourceRémi Denis-Courmont2011-03-091-3/+2
| | | | | | | | | | | | | | The previous Phonet patch series introduced per-socket implicit destination (i.e. connect()). In that case, the destination socket address is NULL in the transmit function. However commit a8059512b120362b15424f152b2548fe8b11bd0c ("Phonet: implement per-socket destination/peer address") is incomplete and would trigger a NULL dereference. (Fortunately, the code is not in released kernel, and in fact currently not reachable.) Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S.

| * sfc: Use write-combining to reduce TX latencyBen Hutchings2011-03-043-10/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on work by Neil Turton <nturton@solarflare.com> and Kieran Mansley <kmansley@solarflare.com>. The BIU has now been verified to handle 3- and 4-dword writes within a single 128-bit register correctly. This means we can enable write- combining and only insert write barriers between writes to distinct registers. This has been observed to save about 0.5 us when pushing a TX descriptor to an empty TX queue. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Fiber Channel over Ethernet (FCoE) Direct Data Placement (DDP) can also be used for FCoE target, where the DDP used for read I/O on an initiator can be used on an FCoE target to speed up the write I/O to the target from the initiator. The added ndo_fcoe_ddp_target() works in the similar way as the existing ndo_fcoe_ddp_setup() to allow the underlying hardware set up the DDP context accordingly when it gets called from the FCoE target implementation on top the existing Open-FCoE fcoe/libfc protocol stack so without losing the ability to provide DDP for read I/O as an initiator, it can also provide DDP offload to the write I/O coming from the initiator as a target.

First, if the route has an explicit preferred source address specified, then we use that. Otherwise we search the route's outgoing interface for a suitable address. This search can be precomputed and cached at route insertion time. The only missing part is that we have to refresh this precomputed value any time addresses are added or removed from the interface, and this is accomplished by fib_update_nh_saddrs().

Checking this every route lookup is pointless work. Instead validate it during route insertion, via fib_create_info(). Also, there was nothing making sure the type value was less than RTN_MAX, so add that missing check while we're here. Signed-off-by: David S. Miller <davem@davemloft.net>
