Like in commit 44713b67db10c774f14280c129b0d5fd13c70cf2 ("ipv4: Optimize flow initialization in output route lookup." we can optimize the on-stack flow setup to only initialize the members which are actually used.

2011-03-09tcp: ioctl type SIOCOUTQNSD returns amount of data not sentMario Schuknecht2-1/+12
In contrast to SIOCOUTQ which returns the amount of data sent but not yet acknowledged plus data not yet sent this patch only returns the data not sent. For various methods of live streaming bitrate control it may be helpful to know how much data are in the tcp outqueue are not sent yet.

2011-03-09Phonet: kill the ST-Ericsson pipe controller KconfigRémi Denis-Courmont4-52/+0
This is now a run-time choice so that a single kernel can support both old and new generation ISI modems. Support for manually enabling the pipe flow is removed as it did not work properly, does not fit well with the socket API, and I am not aware of any use at the moment.

2011-03-09Phonet: support active connection without pipe controller on modemRémi Denis-Courmont3-162/+165
This provides support for newer ISI modems with no need for the earlier experimental compile-time alternative choice. With this, we can now use the same kernel and userspace with both types of modems. This also avoids confusing two different and incompatible state machines, actively connected vs accepted sockets, and adds connection response error handling (processing "SYN/RST" of sorts).

2011-03-09Phonet: provide pipe socket option to retrieve the pipe identifierRémi Denis-Courmont3-12/+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.

2011-03-09Phonet: allocate sock from accept syscall rather than soft IRQRémi Denis-Courmont3-174/+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>
2011-03-09Phonet: factor common code to send control messagesRémi Denis-Courmont1-152/+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>
2011-03-09Phonet: correct pipe backlog callback return valuesRémi Denis-Courmont1-14/+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).

2011-03-09Phonet: return an error when packet TX failsRémi Denis-Courmont1-5/+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.

2011-03-09Phonet: fix NULL dereference on TX path with implicit sourceRémi Denis-Courmont1-3/+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. Miller <davem@davemloft.net>

2011-03-08ipv4: Fix scope value used in route src-address caching.David S. Miller2-2/+4

2011-03-07ipv4: Cache source address in nexthop entries.David S. Miller3-9/+31
When doing output route lookups, we have to select the source address if the user has not specified an explicit one. 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().

2011-03-07net: add ndo_fcoe_ddp_target() to support FCoE DDP in target modeYi Zou1-0/+4
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.
