* mac80211: validate TIM IE length (redux)Johannes Berg2009-04-22
| | | | | | | | | | | | | | | | | | | The TIM IE must not be shorter than 4 bytes, so verify that when parsing it and use the proper type. To ease that adjust struct ieee80211_tim_ie to have a virtual bitmap of size at least 1. Also check that the TIM IE is actually present before trying to parse it! Because other people may need the function, make it a static inline in ieee80211.h. (The original "mac80211: validate TIM IE length" was a minimal fix for 2.6.30. This purports to be the full, correct fix. -- JWL) Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* nl80211: Add set/get for frag/rts threshold and retry limitsJouni Malinen2009-04-22
| | | | | | | | | | | | | | | | Add new nl80211 attributes that can be used with NL80211_CMD_SET_WIPHY and NL80211_CMD_GET_WIPHY to manage fragmentation/RTS threshold and retry limits. Since these values are stored in struct wiphy, remove the local copy from mac80211 where feasible (frag & rts threshold). The retry limits are currently needed in struct ieee80211_conf, but these could be eventually removed since the driver should have access to the values in struct wiphy.

* cfg80211: clean up includesJohannes Berg2009-04-22
| | | | | | | | | | | | | | | | | | | | | | | Trying to separate header files into net/wireless.h and net/cfg80211.h has been a source of confusion. Remove net/wireless.h (because there also is the linux/wireless.h) and subsume everything into net/cfg80211.h -- except the definitions for regulatory structures which get moved to a new header net/regulatory.h. The "new" net/cfg80211.h is now divided into sections. There are no real changes in this patch but code shuffling and some very minor documentation fixes. I have also, to make things reflect reality, put in a copyright line for Luis to net/regulatory.h since that is probably exclusively written by him but was formerly in a file that only had my copyright line.

* cfg80211/nl80211: add IBSS APIJohannes Berg2009-04-22
| | | | | | | | | | | | | | | | | | | | | | | This adds IBSS API along with (preliminary) wext handlers. The wext handlers can only do IBSS so you need to call them from your own wext handlers if the mode is IBSS. The nl80211 API requires * an SSID * a channel (frequency) for the case that a new IBSS has to be created It optionally supports * a flag to fix the channel * a fixed BSSID The cfg80211 code also takes care to leave the IBSS before the netdev is set down. If wireless extensions are used, it also caches values when the interface is down and instructs the driver to join when the interface is set up.

* mac80211: disable powersave if pm_qos asks for low latencyJohannes Berg2009-04-22
| | | | | | | | | | When an application asks for a latency lower than the beacon interval there's nothing we can do -- we need to stay awake and not have the AP buffer frames for us.

* mac80211: add hardware restart functionJohannes Berg2009-04-22
| | | | | | | | | | | | | | | Some hardware defects may require the hardware to be re-initialised completely from scratch. Drivers would need much information (for instance the current MAC address, crypto keys, beaconing information, etc.) stored duplicated from mac80211 to be able to do this, so let mac80211 help them. The new ieee80211_restart_hw() function requires the same code as resuming, so move that code into a new ieee80211_reconfig() function in util.c and leave only the suspend code in pm.c.

* libertas: add support for Marvell SD8688 chipBing Zhao2009-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | libertas: add support for Marvell SD8688 chip Use RxPD->pkt_ptr to locate eth803 header in the packet received since SD8688/v10 firmware allows a gap between RxPD and eth803 header. Set SDIO block size to 256 for CMD53. The maximum block size for SD8688 WLAN function is set to 512 in TPLFE_MAX_BLK_SIZE. But using 512 as block size results upto 2K bytes data (4 blocks) being transferred and causes buffer overflow in firmware. Both changes above are backward compatible with earlier firmware versions for SD8385/SD8686.

| | | | | | | | | | | | | | | | Define a new nl80211 event, NL80211_CMD_MICHAEL_MIC_FAILURE, to be used to notify user space about locally detected Michael MIC failures. This matches with the MLME-MICHAELMICFAILURE.indication() primitive. Since we do not actually have TSC in the skb anymore when mac80211_ev_michael_mic_failure() is called, that function is changed to take in the TSC as an optional parameter instead of as a requirement to include the TSC after the hdr field (which we did not really follow). For now, TSC is not included in the events from mac80211, but it could be added at some point. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | aio_write gets const struct iovec * but tun_chr_aio_write casts this to struct iovec * and modifies the iovec. As a result, attempts to use io_submit to send packets to a tun device fail with weird errors such as EINVAL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The removal of the SAME target accidentally removed one feature that is not available from the normal NAT targets so far, having multi-range mappings that use the same mapping for each connection from a single client. The current behaviour is to choose the address from the range based on source and destination IP, which breaks when communicating with sites having multiple addresses that require all connections to originate from the same IP address. Introduce a IP_NAT_RANGE_PERSISTENT option that controls whether the destination address is taken into account for selecting addresses. http://bugzilla.kernel.org/show_bug.cgi?id=12954 Signed-off-by: Patrick McHardy <kaber@trash.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Marvell 88E1121R Dual PHY device can be hardware-configured to use shared interrupt pin for both PHY ports. For such PHY configurations using shared PHY interrupt phy_interrupt() handler will also schedule a work for PHY port which didn't cause an interrupt. This patch adds a possibility for PHY drivers to provide did_interrupt() function which reports if the PHY (or a PHY port in a multi-PHY device) generated an interrupt. This function is called in phy_change() as phy_change() shouldn't proceed if it is invoked for a PHY which didn't cause an interrupt. So check for interrupt originator in phy_change() to allow early-out. Signed-off-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: David S. Miller <davem@davemloft.net>

But when such taint happens, a developer might still be working on the kernel, expecting that lockdep is still enabled. But a taint disables lockdep without ever warning about it. Such a kernel behaviour doesn't really help for kernel development. This patch adds this missing warning. Since the taint is done most of the time after the main message that explain the real source issue, it seems safe to warn about it inside add_taint() so that it appears at last, without hurting the main information. v2: Use a generic helper to disable lockdep instead of an open coded xchg().

However, before capabilities the privilege to call these did in fact depend upon fsuid==0. This patch introduces those capabilities into the fsmask, restoring the old behavior. See the thread starting at http://lkml.org/lkml/2009/3/11/157 for reference. Note that if this fix is deemed valid, then earlier kernel versions (2.4 and 2.2) ought to be fixed too.
