* cfg80211: introduce scan IE limit attributeJohannes Berg2009-04-221-0/+4
| | | | | | | | | | | This patch introduces a new attribute for a wiphy that tells userspace how long the information elements added to a probe request frame can be at most. It also updates the at76 to advertise that it cannot support that, and, for now until I can fix that, iwlwifi too. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* nl80211: Add Michael MIC failure eventJouni Malinen2009-04-221-0/+28
| | | | | | | | | | | | | | | | 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>
* rfkill: remove user_claim stuffJohannes Berg2009-04-221-6/+0
| | | | | | | | | | | Almost all drivers do not support user_claim, so remove it completely and always report -EOPNOTSUPP to userspace. Since userspace cannot really drive rfkill _anyway_ (due to the odd restrictions imposed by the documentation) having this code is just pointless.

* tun: fix tun_chr_aio_write so that aio worksMichael S. Tsirkin2009-04-212-3/+4
| | | | | | | | | | | | | 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. Since tun is the only user of skb_copy_datagram_from_iovec, we can fix this simply by changing the later so that it does not touch the iovec passed to it. Signed-off-by: Michael S.

* net: skb_copy_datagram_const_iovec()Michael S. Tsirkin2009-04-212-0/+7
| | | | | | | | | | | | | There's an skb_copy_datagram_iovec() to copy out of a paged skb, but it modifies the iovec, and does not support starting at an offset in the destination. We want both in tun.c, so let's add the function. It's a carbon copy of skb_copy_datagram_iovec() with enough changes to be annoying. Signed-off-by: Michael S.

* syncookies: remove last_synq_overflow from struct tcp_sockFlorian Westphal2009-04-201-3/+1
| | | | | | | | | | | | | | | last_synq_overflow eats 4 or 8 bytes in struct tcp_sock, even though it is only used when a listening sockets syn queue is full. We can (ab)use rx_opt.ts_recent_stamp to store the same information; it is not used otherwise as long as a socket is in listen state. Move linger2 around to avoid splitting struct mtu_probe across cacheline boundary on 32 bit arches. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>

| * phylib: Allow early-out in phy_changeAnatolij Gustschin2009-04-131-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

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.

Some applications which perform job-scheduling functions consult the load average when making decisions. If a cgroup is frozen, the load average does not provide a useful measure of the system's utilization to such applications. This is especially inconvenient if the job scheduler employs the cgroup freezer as a mechanism for preempting low priority jobs. Contrast this with using SIGSTOP for the same purpose: the stopped tasks do not count toward system load. Change task_contributes_to_load() to return false if the task is frozen. This results in /proc/loadavg behavior that better meets users' expectations.

Also, in the case that the OTG transceiver handles charger control when connected to USB, a regulator named "ac_draw" can be supplied instead of the custom set_charge callback to control the charger when connected to AC. The check for (transceiver->state == OTG_STATE_B_PERIPHERAL) in otg_is_usb_online is probably too simple, I'm just using this with a peripheral only device and gpio_vbus + bq24022. I'm not sure which other OTG states can supply power. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>

But the voltage drop in Li-ion batteries is marginal(1~2 %) till about 80% of its capacity - which means, after a BATFULL, charging won't be restarted until 80%. This work_struct function restarts charging at regular intervals to make sure the battery doesn't discharge too much.
