* caif-hsi: Fix merge issues.Sjur Brændeland2012-06-29
| | | | | | | | | | | | | | Fix the failing merge in net-next by reverting the last net-next merge for caif_hsi.c and then merge in the commit: "caif-hsi: Bugfix - Piggyback'ed embedded CAIF frame lost" from the net repository. The commit:"caif-hsi: Add missing return in error path" from net repository was dropped, as it changed code previously removed in the net-next repository.

* ipv4: Adjust in_dev handling in fib_validate_source()David S. Miller2012-06-28
| | | | | | | | | Checking for in_dev being NULL is pointless. In fact, all of our callers have in_dev precomputed already, so just pass it in and remove the NULL checking. Signed-off-by: David S. Miller <davem@davemloft.net>
* ipv4: Fix bugs in fib_compute_spec_dst().David S. Miller2012-06-28
| | | | | | | | | | | | | | | | Based upon feedback from Julian Anastasov. 1) Use route flags to determine multicast/broadcast, not the packet flags. 2) Leave saddr unspecified in flow key. 3) Adjust how we invoke inet_select_addr(). Pass ip_hdr(skb)->saddr as second arg, and if it was zeronet use link scope. 4) Use loopback as input interface in flow key. Signed-off-by: David S. Miller <davem@davemloft.net>
* net: Use NLMSG_DEFAULT_SIZE in combination with nlmsg_new()Thomas Graf2012-06-28
| | | | | | | | | | | | | | | | | | | Using NLMSG_GOODSIZE results in multiple pages being used as nlmsg_new() will automatically add the size of the netlink header to the payload thus exceeding the page limit. NLMSG_DEFAULT_SIZE takes this into account.

* tcp: plug dst leak in tcp_v6_conn_request()Neal Cardwell2012-06-28
| | | | | | | | | | | | | | | The code in tcp_v6_conn_request() was implicitly assuming that tcp_v6_send_synack() would take care of dst_release(), much as tcp_v4_send_synack() already does. This resulted in tcp_v6_conn_request() leaking a dst if sysctl_tw_recycle is enabled. This commit restructures tcp_v6_send_synack() so that it accepts a dst pointer and takes care of releasing the dst that is passed in, to plug the leak and avoid future surprises by bringing the IPv6 behavior in line with the IPv4 side.

* tcp: use inet6_csk_route_req() in tcp_v6_send_synack()Neal Cardwell2012-06-28
| | | | | | | | | | | With the recent change (earlier in this patch series) to set flowi6_oif to treq->iif in inet6_csk_route_req(), the dst lookup in these two functions is now identical, so tcp_v6_send_synack() can now just call inet6_csk_route_req(), to reduce code duplication and keep things closer to the IPv4 side, which is structured this way.

* tcp: pass fl6 to inet6_csk_route_req()Neal Cardwell2012-06-28
| | | | | | | | | | This commit changes inet_csk_route_req() so that it uses a pointer to a struct flowi6, rather than allocating its own on the stack. This brings its behavior in line with its IPv4 cousin, inet_csk_route_req(), and allows a follow-on patch to fix a dst leak.

* tcp: fix inet6_csk_route_req() for link-local addressesNeal Cardwell2012-06-28
| | | | | | | | | | | Fix inet6_csk_route_req() to use as the flowi6_oif the treq->iif, which is correctly fixed up in tcp_v6_conn_request() to handle the case of link-local addresses. This brings it in line with the tcp_v6_send_synack() code, which is already correctly using the treq->iif in this way. Signed-off-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.

Eliad Peller provides a mac80211 fix to prevent some frames from being built with an invalid BSSID. Eric Dumazet sends an NFC fix to prevent a BUG caused by a NULL pointer dereference. Felix Fietkau has an ath9k fix for a regression causing LEAP-authenticated connection failures. Johannes Berg provides an iwlwifi fix that eliminates some log SPAM after an authentication/association timeout. He also provides a mac80211 fix to prevent incorrectly addressing certain action frames (and in so doing, to comply with the 802.11 specs). Larry Finger provides a few USB IDs for the rtl8192cu driver -- should be harmless. Panayiotis Karabassis provices a one-liner to fix kernel bug 42903 (a system freeze). Randy Dunlap provides a one-line Kconfig change to prevent build failures with some configurations. Stone Piao provides an mwifiex sequence numbering fix and a fix to prevent mwifiex from attempting to include eapol frames in an aggregation frame.

The cause turns out to be that when the AP station is added but we don't associate, the IWL_STA_UCODE_INPROGRESS is set but never cleared. This then causes iwl_restore_stations() to attempt to resend it because it uses the flag internally and uploads even if it didn't set it itself. To fix this issue and not upload the station again when it has already been removed by mac80211, clear the flag after adding it in case we add it only for association.

This caused a regression when using WEP-LEAP. This patch fixes the regression by keeping track of which key indexes refer to CCMP keys and only using the key miss indication for those.

While handling events, we perform skb_pull(skb, 4) to remove event header. Corresponding skb_push() call is missing while submitting the buffer. 2) For PCIe interface, event skb is passed with event header. Recently added uAP events EVENT_UAP_STA_ASSOC, EVENT_UAP_STA_DEAUTH will not work for PCIe, as they assume event skb points to event body.

It's observed that WPS handshake fails with some 11n AP. The reason for the failure is that the eapol packet is sent via 11n frame aggregation. The eapol packet should be sent directly without 11n aggregation. This patch fixes the problem by adding WPS session control while dequeuing Tx packets for transmission.

If a sequence hole is detected, start_win is updated to next sequence number. Since the rx sequence number is initialized to 0, a corner case exists when BA setup happens immediately after association. As 0 is a valid sequence number, start_win gets increased to 1 incorrectly. This causes the first packet with sequence number 0 being dropped. Initialize rx sequence number as 0xffff and skip adjusting start_win if the sequence number remains 0xffff. The sequence number will be updated once the first packet is received.

That is, if the coalescing flag is 0 for a given Rx/Tx queue then the corresponding coalescing register should be cleared. This behavior is correctly implemented for the single-queue mode (SQ_SG_MODE), but not for the multi-queue mode (MQ_MG_MODE). This fixes the later case.

The only place this matters is in qmi_wwan_cdc_wdm_manage_power which is called from cdc_wdm. Simply testing for NULL intfdata there is sufficient to allow it to continue working at all times.
