This patch fixes double pairing issues with Secure Simple Paring support. It was observed that when pairing with SSP enabled, that the confirmation will be asked twice. http://www.spinics.net/lists/linux-bluetooth/msg02473.html This also causes bug when initiating SSP connection from Windows Vista. The reason is because bluetoothd does not store link keys since HCIGETAUTHINFO returns 0. Setting default to general bonding fixes these issues. Signed-off-by:

When 802.11g was introduced, we had RTS/CTS and CTS-to-Self protection mechanisms. In an HT Beacon, HT stations use the "Operating Mode" field in the HT Information Element to determine whether or not to use protection. The Operating Mode field has 4 possible settings: 0-3: Mode 0: If all stations in the BSS are 20/40 MHz HT capable, or if the BSS is 20/40 MHz capable, or if all stations in the BSS are 20 MHz HT stations in a 20 MHz BSS Mode 1: used if there are non-HT stations or APs using the primary or secondary channels Mode 2: if only HT stations are associated in the BSS and at least one 20 MHz HT station is associated. Mode 3: used if one or more non-HT stations are associated in the BSS. When in operating modes 1 or 3, and the Use_Protection field is 1 in the Beacon's ERP IE, all HT transmissions must be protected using RTS/CTS or CTS-to-Self. By default, CTS-to-self is the preferred protection mechanism for less overhead and higher throughput; but using the full RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment. For 6000 series WIFI NIC, RTS/CTS protection mechanism is the recommended choice for HT traffic based on the HW design. Signed-off-by:

ops->set_tim() must be atomic, so b43 trying to acquire a mutex leads to a kernel crash. This patch trades an easy to trigger crash in AP mode for an unlikely race condition. According to Michael, the real fix would be to allow set_tim() to sleep, since b43 is not the only driver that needs to sleep in all callbacks. Signed-off-by:

On older kernels, e.g. 2.6.27, a WARN_ON dump in rtmsg_ifinfo() is thrown when the CAN device is registered due to insufficient skb space, as reported by various users. This patch adds the rtnl_link_ops "get_size" to fix the problem. I think this patch is required for more recent kernels as well, even if no WARN_ON dumps are triggered. Maybe we also need "get_xstats_size" for the CAN xstats. Signed-off-by:

RFC 2003 requires the outer header to have DF set if DF is set on the inner header, even when PMTU discovery is off for the tunnel. Our implementation does exactly that. For this to work properly the IPIP gateway also needs to engate in PMTU when the inner DF bit is set. As otherwise the original host would not be able to carry out its PMTU successfully since part of the path is only visible to the gateway. Unfortunately when the tunnel PMTU discovery setting is off, we do not collect the necessary soft state, resulting in blackholes when the original host tries to perform PMTU discovery. This problem is not reproducible on the IPIP gateway itself as the inner packet usually has skb->local_df set. This is not correctly cleared (an unrelated bug) when the packet passes through the tunnel, which allows fragmentation to occur. For hosts behind the IPIP gateway it is readily visible with a simple ping. This patch fixes the problem by performing PMTU discovery for all packets with the inner DF bit set, regardless of the PMTU discovery setting on the tunnel itself. Signed-off-by:

Vitezslav Samel discovered that since 2.6.30.4+ active FTP can not work over NAT. The "cause" of the problem was a fix of unacknowledged data detection with NAT (commit a3a9f79e). However, actually, that fix uncovered a long standing bug in TCP conntrack: when NAT was enabled, we simply updated the max of the right edge of the segments we have seen (td_end), by the offset NAT produced with changing IP/port in the data. However, we did not update the other parameter (td_maxend) which is affected by the NAT offset. Thus that could drift away from the correct value and thus resulted breaking active FTP. The patch below fixes the issue by *not* updating the conntrack parameters from NAT, but instead taking into account the NAT offsets in conntrack in a consistent way. (Updating from NAT would be more harder and expensive because it'd need to re-calculate parameters we already calculated in conntrack.) Signed-off-by:

As reported by Rick Farina (sidhayn@gmail.com), removing the RTL8187 USB stick, or unloading the driver rtl8187 using rmmod will cause a kernel oops. There are at least two forms of the failure, (1) BUG: Scheduling while atomic, and (2) a fatal kernel page fault. This problem is reported in Bugzilla #14539. This problem does not occur for kernel 2.6.31, but does for 2.6.32-rc2, thus it is technically a regression; however, bisection did not locate any faulty patch. The fix was found by comparing the faulty code in rtl8187 with p54usb. My interpretation is that the handling of work queues in mac80211 changed enough to the LEDs to be unregistered before tasks on the work queues are cancelled. Previously, these actions could be done in either order. (Herton Ronaldo Krzesinski <herton@mandriva.com.br> reports that the code is the same in 2.6.31, so this may be a candidate for 2.6.31.x. -- JWL) Signed-off-by:
