2011-01-19Bluetooth: Create a unified auth_type evaluation functionJohan Hedberg1-49/+28
The logic for determining the needed auth_type for an L2CAP socket is rather complicated and has so far been duplicated in l2cap_check_security as well as l2cap_do_connect. Additionally the l2cap_check_security code was completely missing the handling of SOCK_RAW type sockets. This patch creates a unified function for the evaluation and makes l2cap_do_connect and l2cap_check_security use that function.

2011-01-19Revert "Bluetooth: Update sec_level/auth_type for already existing connections"Johan Hedberg1-5/+0
This reverts commit 045309820afe047920a50de25634dab46a1e851d. That commit is wrong for two reasons: - The conn->sec_level shouldn't be updated without performing authentication first (as it's supposed to represent the level of security that the existing connection has) - A higher auth_type value doesn't mean "more secure" like the commit seems to assume. E.g. dedicated bonding with MITM protection is 0x03 whereas general bonding without MITM protection is 0x04. hci_conn_auth already takes care of updating conn->auth_type so hci_connect doesn't need to do it.

2011-01-17ath9k_hw: do PA offset calibration only on longcal intervalRajkumar Manoharan1-5/+5
The power detector adc offset calibration has to be done on 4 minutes interval (longcal * pa_skip_count). But the commit "ath9k_hw: fix a noise floor calibration related race condition" makes the PA calibration executed more frequently beased on nfcal_pending value. Running PAOffset calibration lesser than longcal interval doesn't help anything and the worse part is that it causes NF load timeouts and RX deaf conditions. In a very noisy environment, where the distance b/w AP & station is ~10 meter and running a downlink udp traffic with frequent background scan causes "Timeout while waiting for nf to load: AR_PHY_AGC_CONTROL=0x40d1a" and moves the chip into deaf state. This issue was originaly reported in Android platform where the network-manager application does bgscan more frequently on AR9271 chips. (AR9285 family usb device).

Since the introduction of the fixes for the reorder timer, mac80211 will cause lockdep warnings because lockdep confuses local->skb_queue and local->rx_skb_queue and treats their lock as the same.

This is an attempt to fix a long standing open bug: http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1334 The interrupt handler checks for INTA being -1, apparently that means that the hardware is gone. But the interrupt handler defers actual interrupt processing to a tasklet. By the time the tasklet is run and checks INTA again, the hardware might be gone and INTA be -1, which confuses the driver because all event bits are set. The patch applies to 2.6.37.

2011-01-09net offloading: Accept NETIF_F_HW_CSUM for all protocols.Jesse Gross1-1/+1
We currently only have software fallback for one type of checksum: the TCP/UDP one's complement. This means that a protocol that uses hardware offloading for a different type of checksum (FCoE, SCTP) must directly check the device's features and do the right thing ahead of time. By the time we get to dev_can_checksum(), we're only deciding whether to apply the one algorithm in software or hardware. NETIF_F_HW_CSUM has the same capabilities as the software version, so we should always use it if present. The primary advantage of this is multiply tagged vlans can use hardware checksumming.
