| * | | mac80211: add ieee80211_vif param to tsf functionsEliad Peller2011-09-271-3/+4
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TSF can be kept per vif. Add ieee80211_vif param to set/get/reset_tsf, and move the debugfs entries to the per-vif directory. Update all the drivers that implement these callbacks. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * | Bluetooth: Add mgmt events for blacklistingAntti Julku2011-09-212-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add management interface events for blocking/unblocking a device. Sender of the block device command gets cmd complete and other mgmt sockets get the event. Event is also sent to mgmt sockets when blocking is done with ioctl, e.g when blocking a device with hciconfig. This makes it possible for bluetoothd to track status of blocked devices when a third party block or unblocks a device. Event sending is handled in mgmt_device_blocked function which gets called from hci_blacklist_add in hci_core.c. A pending command is added in mgmt_block_device, so that it can found when sending the event - the event is not sent to the socket from which the pending command came. Locks were moved out from hci_core.c to hci_sock.c and mgmt.c, because locking is needed also for mgmt_pending_add in mgmt.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One piece of information that was lost when using the mgmt interface, was the type of the connection. Using HCI events we used to know the type of the connection based on the type of the event, e.g. HCI_LE_Connection_Complete for LE links.

| * | Bluetooth: Add a flag to indicate that SMP is going onVinicius Costa Gomes2011-09-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add HCI_CONN_LE_SMP_PEND flag to indicate that SMP is pending for that connection. This allows to have information that an SMP procedure is going on for that connection. We use the HCI_CONN_ENCRYPT_PEND to indicate that encryption (HCI_LE_Start_Encryption) is pending for that connection. While a SMP procedure is going on we hold an reference to the connection, to avoid disconnections. Signed-off-by: Vinicius Costa Gomes <vinicius.gomes@openbossa.org> Signed-off-by: Gustavo F.

This is because we now take a reference on pid and cred in each write(), and release them in read(), usually done from another process, eventually from another cpu.

This is because TCP_ECN_check_ce() considers that if no ECT is seen on a segment, this is because this segment was a retransmit. Refine this heuristic and apply it only if we seen ECT in a previous segment, to detect ECN blackhole at IP level.

To deal with the issue add new SCTP command which can be used to set association explictly.

| * | | nl80211/cfg80211: add match filtering for sched_scanLuciano Coelho2011-09-131-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce filtering for scheduled scans to reduce the number of unnecessary results (which cause useless wake-ups). Add a new nested attribute where sets of parameters to be matched can be passed when starting a scheduled scan. Only scan results that match any of the sets will be returned. At this point, the set consists of a single parameter, an SSID. This can be easily extended in the future to support more complex matches.

Since firmware based roaming is faster, inform wpa_supplicant to avoid roaming and let the firmware decide to roam if necessary. For fullmac drivers like ath6kl, it is just enough to provide the ESSID and the firmware will decide on the BSSID. Since it is not possible to do pre-auth during roaming for fullmac drivers, the wpa_supplicant needs to completely disconnect with the old AP and reconnect with the new AP. This consumes lot of time and it is better to leave the roaming decision to the firmware. Signed-off-by: Vivek Natarajan <nataraja@qca.qualcomm.com> Signed-off-by: John W.

* | | | tcp: md5: remove one indirection level in tcp_md5sig_poolEric Dumazet2011-09-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tcp_md5sig_pool is currently an 'array' (a percpu object) of pointers to struct tcp_md5sig_pool. Only the pointers are NUMA aware, but objects themselves are all allocated on a single node. Remove this extra indirection to get proper percpu memory (NUMA aware) and make code simpler.
