2012-01-26netns: fix net_alloc_generic()Eric Dumazet1-15/+16
When a new net namespace is created, we should attach to it a "struct net_generic" with enough slots (even empty), or we can hit the following BUG_ON() : [ 200.752016] kernel BUG at include/net/netns/generic.h:40! ...

2012-01-26tcp: bind() fix autoselection to share portsFlavio Leitner1-0/+5
The current code checks for conflicts when the application requests a specific port. If there is no conflict, then the request is granted. On the other hand, the port autoselection done by the kernel fails when all ports are bound even when there is a port with no conflict available. The fix changes port autoselection to check if there is a conflict and use it if not.

2012-01-26l2tp: l2tp_ip - fix possible oops on packet receiveJames Chapman1-5/+0
When a packet is received on an L2TP IP socket (L2TPv3 IP link encapsulation), the l2tpip socket's backlog_rcv function calls xfrm4_policy_check(). This is not necessary, since it was called before the skb was added to the backlog. With CONFIG_NET_NS enabled, xfrm4_policy_check() will oops if skb->dev is null, so this trivial patch removes the call. This bug has always been present, but only when CONFIG_NET_NS is enabled does it cause problems. Most users are probably using UDP encapsulation for L2TP, hence the problem has only recently surfaced.

2012-01-25rds: Make rds_sock_lock BH rather than IRQ safe.David S. Miller1-12/+8
rds_sock_info() triggers locking warnings because we try to perform a local_bh_enable() (via sock_i_ino()) while hardware interrupts are disabled (via taking rds_sock_lock). There is no reason for rds_sock_lock to be a hardware IRQ disabling lock, none of these access paths run in hardware interrupt context. Therefore making it a BH disabling lock is safe and sufficient to fix this bug. Reported-by: Kumar Sanghvi <kumaras@chelsio.com> Reported-by: Josh Boyer <jwboyer@gmail.com> Signed-off-by: David S.

2012-01-24iwlwifi: fix PCI-E transport "inta" raceJohannes Berg1-2/+2
When an interrupt comes in, we read the reason bits and collect them into "trans_pcie->inta". This happens with the spinlock held. However, there's a bug resetting this variable -- that happens after the spinlock has been released. This means that it is possible for interrupts to be missed if the reset happens after some other interrupt reasons were already added to the variable. I found this by code inspection, looking for a reason that we sometimes see random commands time out. It seems possible that this causes such behaviour, but I can't say for sure right now since it happens extremely infrequently on my test systems.

__ieee80211_recalc_idle() iterates through the vifs, sets bss_conf.idle = true if they are disconnected, and increases "count" if they are not (which later gets evaluated in order to determine whether the device is idle). However, the loop doesn't set bss_conf.idle = false (along with increasing "count"), causing the device idle state and the vif idle state to get out of sync in some cases.

This is required in order to support multiple targets. Note that currently supported drivers (PN533 and NCI) don't use the target_idx in their implementation.

2012-01-24mac80211: remove useless DA checking in ieee80211_rx_mgmt_probe_resp()Antonio Quartulli1-3/+0
Actually the DA field has already been checked along the rx path (in prepare_for_handlers()) and this check is therefore useless at this point. Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-01-24mwifiex: derive priv from net_device instead of wiphyYogesh Ashok Powar1-11/+8
Currently mwifiex_private pointers are derived from wiphy structures. This will always work as long as there is only one net_device associated with one wiphy. In scenarios where there are multiple net_devices associated with single wiphy, one should use net_device to derive the priv.

2012-01-24mwifiex: use bss_type and bss_num to retrieve privYogesh Ashok Powar12-34/+31
Current implementation, for retrieving priv from adapter, uses bss_index. In multi interface environment supporting different types, bss_index may not be unique. Use bss_type along with bss_num to retrieve the priv. bss_index is removed with this change.

The SPROM location has been relocated again for some devices. This patch will log the offset when CONFIG_BCMA_DEBUG has been selected. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-01-24mac80211: Fix the maximum transmit power with power constraintHong Wu2-2/+3
The local maximum transmit power for a channel is defined as the maximum regulatory transmission power minus the local power constraint specified for the channel in the Power Constraint element.

2012-01-24wireless: Save original maximum regulatory transmission power for the ↵Hong Wu2-17/+4
calucation of the local maximum transmit power The local maximum transmit power is the maximum power a wireless device allowed to transmit. If Power Constraint is presented, the local maximum power equals to the maximum allowed power defined in regulatory domain minus power constraint. The maximum transmit power is maximum power a wireless device capable of transmitting, and should be used in Power Capability element (7.3.2.16 IEEE802.11 2007). The transmit power from a wireless device should not greater than the local maximum transmit power. The maximum transmit power was not calculated correctly in the current Linux wireless/mac80211 when Power Constraint is presented. Signed-off-by: Hong Wu <hong.wu@dspg.com> Signed-off-by: John W.

On carl9170, HW encryption is disabled on IBSS; the mac80211 software-based encryption is used instead. As mac80211 supports IBSS RSN (per-STA GTK), claim its support in the carl9170 PHY.
