2011-02-28netlink: handle errors from netlink_dump()Andrey Vagin
netlink_dump() may failed, but nobody handle its error. It generates output data, when a previous portion has been returned to user space. This mechanism works when all data isn't go in skb. If we enter in netlink_recvmsg() and skb is absent in the recv queue, the netlink_dump() will not been executed. So if netlink_dump() is failed one time, the new data never appear and the reader will sleep forever. netlink_dump() is called from two places: 1. from netlink_sendmsg->...->netlink_dump_start(). In this place we can report error directly and it will be returned by sendmsg(). 2. from netlink_recvmsg There we can't report error directly, because we have a portion of valid output data and call netlink_dump() for prepare the next portion. If netlink_dump() is failed, the socket will be mark as error and the next recvmsg will be failed. Signed-off-by: Andrey Vagin <avagin@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-02-25mac80211: support direct offchannel TX offloadJohannes Berg
For devices supported by iwlwifi sometimes off-channel transmissions need to be handled by the device completely. To support this mac80211 needs to pass the frame directly to the driver and not through the TX path as the driver needs the frame and channel information at the same time.

2011-02-25mac80211: make tx() operation return voidJohannes Berg
The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.

2011-02-25[net/9p] Small non-IO PDUs for zero-copy supporting transports.Venkateswararao Jujjuri (JV)
If a transport prefers payload to be sent separate from the PDU (P9_TRANS_PREF_PAYLOAD_SEP), there is no need to allocate msize PDU buffers(struct p9_fcall). This patch allocates only upto 4k buffers for this kind of transports and there won't be any change to the legacy transports. Hence, this patch on top of zero copy changes allows user to specify higher msizes through the mount option without hogging the kernel heap.

2011-02-25[net/9p] Handle Zero Copy TREAD/RERROR case in !dotl case.Venkateswararao Jujjuri (JV)
This takes care of copying out error buffers from user buffer payloads when we are using zero copy. This happens because the only payload buffer the server has to respond to the request is the user buffer given for the zero copy read. Because we only use zerocopy when the amount of data to transfer is greater than a certain size (currently 4K) and error strings are limited to ERRMAX (currently 128) we don't need to worry about there being sufficient space for the error to fit in the payload.

This patch adds preferences field to the p9_trans_module.

2011-02-25[net/9p] Preparation and helper functions for zero copyVenkateswararao Jujjuri (JV)
This patch prepares p9_fcall structure for zero copy. Added fields send the payload buffer information to the transport layer. In addition it adds a 'private' field for the transport layer to store mapped/pinned page information so that it can be freed/unpinned during req_done. This patch also creates trans_common.[ch] to house helper functions. It adds the following helper functions. p9_release_req_pages - Release pages after the transaction. p9_nr_pages - Return number of pages needed to accomodate the payload. payload_gup - Translates user buffer into kernel pages.
