[PF_KEY]: Fix ipsec not working in 2.6.23-rc1-git10
Although an ipsec SA was established, kernel couldn't seem to find it.
I think since we are now using "x->sel.family" instead of "family" in
the xfrm_selector_match() called in xfrm_state_find(), af_key needs to
set this field too, just as xfrm_user.
In af_key.c, x->sel.family only gets set when there's an
ext_hdrs[SADB_EXT_ADDRESS_PROXY-1] which I think is for tunnel.
I think pfkey needs to also set the x->sel.family field when it is 0.

[TCP]: Invoke tcp_sendmsg() directly, do not use inet_sendmsg().
As discovered by Evegniy Polyakov, if we try to sendmsg after
a connection reset, we can do incredibly stupid things.
The core issue is that inet_sendmsg() tries to autobind the
socket, but we should never do that for TCP. Instead we should
just go straight into TCP's sendmsg() code which will do all
of the necessary state and pending socket error checks.
TCP's sendpage already directly vectors to tcp_sendpage(), so this
merely brings sendmsg() in line with that.

USB HID: fix a possible NULL pointer dereference when we fail to allocate memory
If, in usb_hid_configure(), we fail to allocate storage for 'usbhid',
"if (!(usbhid = kzalloc(sizeof(struct usbhid_device), GFP_KERNEL)))",
then we'll jump to the 'fail:' label where we have this code:
usb_free_urb(usbhid->urbin);
usb_free_urb(usbhid->urbout);
usb_free_urb(usbhid->urbctrl);
Since we got here because we couldn't allocate storage for 'usbhid',
what we have here is a NULL pointer dereference - ouch...
This patch solves that little problem by adding a new
'fail_no_usbhid:' label after the problematic calls to
usb_free_urb() and jumps to that one instead, in the problem case.
Some of ASUS' notebooks (e.g G Series) include a tiny oled display, which is
attached to an internal USB bus. Unfortunatly the device reports a wrong

genirq: temporary fix for level-triggered IRQ resend
Marcin Slusarz reported a ne2k-pci "hung network interface" regression.
delayed disable relies on the ability to re-trigger the interrupt in the
case that a real interrupt happens after the software disable was set.
In this case we actually disable the interrupt on the hardware level
_after_ it occurred.
On enable_irq, we need to re-trigger the interrupt. On i386 this relies
on a hardware resend mechanism (send_IPI_self()).
Actually we only need the resend for edge type interrupts. Level type
interrupts come back once enable_irq() re-enables the interrupt line.
I assume that the interrupt in question is level triggered because it is
shared and above the legacy irqs 0-15:
17: 12 IO-APIC-fasteoi eth1, eth0
Looking into the IO_APIC code, the resend via send_IPI_self() happens
unconditionally. So the resend is done for level and edge interrupts.
This makes the problem more mysterious.

Make sure to reduce the rating of the ITC clock if ITCs are drifty. If they

the jitter compensation (useless since drift may increase the differentials
arbitrarily).
Without this patch it is possible that the ITC clock becomes selected as
the system clock on systems with drifty ITCs which will result in
nanosleep hanging.
One can still select the itc clock manually on such systems via
clocksource=itc

systems currently do not boot because the ITC clocksource is broken. It
seems to assume that ITCs are synchronized and as a result nanosleep
hangs (may be fixed in a different patch).
