* mac80211: do not TX injected frames when not allowedLuis R. Rodriguez2009-02-09
| | | | | | | | | | | | | | | | | | Monitor mode is able to TX by using injected frames. We should not allow injected frames to be sent unless allowed by regulatory rules. Since AP mode uses a monitor interfaces to transmit management frames we have to take care to not break AP mode as well while resolving this. We can deal with this by allowing compliant APs solutions to inform mac80211 if their monitor interface is intended to be used for an AP by setting a cfg80211 flag for the monitor interface. hostapd, for example, currently does its own checks to ensure AP mode is not used on channels which require radar detection. Once such solutions are available it can can add this flag for monitor interfaces. Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Luis R.

* mac80211: remove HW_SIGNAL_DBJohannes Berg2009-02-09
| | | | | | | | | | | | | Giving the signal in dB isn't much more useful to userspace than giving the signal in unspecified units. This removes some radiotap information for zd1211 (the only driver using this flag), but it helps a lot for getting cfg80211-based scanning which won't support dB, and zd1211 being dB is a little fishy anyway.

* ath9k: Handle mac80211's RC flags for MCS ratesSujith2009-02-09
| | | | | | | | | | | mac80211 notifies the RC algorithm if RTS/CTS and short preamble are needed. The RC flags for MCS rates are currently not handled by mac80211, and ath9k's RC doesn't set the flags either. Fix this. Also, set the rts_cts_rate_idx inside the RC algorithm.

* mac80211: IBSS join reworkAlina Friedrichsen2009-02-09
| | | | | | | | | | | | | | | | | I hold back this patch for around a week to avoid confusion. This is the second step of "mac80211: Fixed BSSID handling revisited". With it, in the situation of a strange merge to the same BSSID (e.g. caused by a TSF overflow) only reset_tsf() is called. And sta_info_flush_delayed() is only called if you change the network manually, not on an automatic BSSID merge. Signed-off-by: Alina Friedrichsen <x-alina@gmx.net> Signed-off-by: John W.

| | | | | | | | | | | | | | | | This fixes a bug when creating a new IBSS network with a fixed BSSID. The fixed BSSID situation is now with one of my last patches handled in ieee80211_sta_find_ibss() function. It's more robust to test against (ifsta->flags & IEEE80211_STA_PREV_BSSID_SET), because ifsta->state is not seted right in every situation and so the creating of the new IBSS network sometimes hangs after the first try to scan for a network to merge.

* net: Increase default NET_SKB_PAD to 32.David S. Miller2009-02-08
| | | | | | | | | | | | | | | | | | Several devices need to insert some "pre headers" in front of the main packet data when they transmit a packet. Currently we allocate only 16 bytes of pad room and this ends up not being enough for some types of hardware (NIU, usb-net, s390 qeth, etc.) So increase this to 32. Note that drivers still need to check in their transmit routine whether enough headroom exists, and if not use skb_realloc_headroom(). Tunneling, IPSEC, and other encapsulation methods can cause the padding area to be used up. Signed-off-by: David S. Miller <davem@davemloft.net>

| * sunhme: Don't match PCI devices in SBUS probe.David S. Miller2009-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, the OF device tree nodes for SBUS and PCI hme devices have the same device node name on some systems. So if the name of the parent node isn't 'sbus', skip it. Based upon an excellent report and detective work by Meelis Roos and Eric Brower. Signed-off-by: David S.

| * 9p: fix endian issues [attempt 3]Eric Van Hensbergen2009-02-07
| | | | | | | | | | | | | | | | | | | | | | | | When the changes were done to the protocol last release, some endian bugs crept in. This patch fixes those endian problems and has been verified to run on 32/64 bit and x86/ppc architectures. This version of the patch incorporates the correct annotations for endian variables.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Based upon a patch from Atsushi Nemoto <anemo@mba.ocn.ne.jp> -------------------- The commit 649274d993212e7c23c0cb734572c2311c200872 ("net_dma: acquire/release dma channels on ifup/ifdown") added unconditional call of dmaengine_get() to net_dma. The API should be called only if NET_DMA was enabled. -------------------- Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Dan Williams <dan.j.williams@intel.com>
| * 3c509: Fix resume from hibernation for PnP mode.Ondrej Zary2009-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Ondrej Zary <linux@rainbow-software.org> last year, I posted a patch which fixed hibernation on 3c509 cards. That was back in 2.6.24. It worked fine in 2.6.25. But then I stopped using hibernation (as it did not work with my new IT8212 RAID controller). Now I fixed it and noticed that 3c509 does not wake up properly anymore (in 2.6.28) - neither in PnP nor in ISA modes. ifconfig down/up makes the card work again in PnP mode. However, in ISA mode, ifconfig up ends with "No such device" error. Comparing the 3c509 driver between 2.6.25 and 2.6.28, there's only some statistics-related change. So the cause of the problem must be somewhere else. This patch makes the resume work in PnP mode, but it's still not enough for ISA mode. Signed-off-by: David S. Miller <davem@davemloft.net>
