2011-01-25TCP: fix a bug that triggers large number of TCP RST by mistakeJerry Chu
This patch fixes a bug that causes TCP RST packets to be generated on otherwise correctly behaved applications, e.g., no unread data on close,..., etc. To trigger the bug, at least two conditions must be met: 1. The FIN flag is set on the last data packet, i.e., it's not on a separate, FIN only packet. 2. The size of the last data chunk on the receive side matches exactly with the size of buffer posted by the receiver, and the receiver closes the socket without any further read attempt. This bug was first noticed on our netperf based testbed for our IW10 proposal to IETF where a large number of RST packets were observed. netperf's read side code meets the condition 2 above 100%. Before the fix, tcp_data_queue() will queue the last skb that meets condition 1 to sk_receive_queue even though it has fully copied out (skb_copy_datagram_iovec()) the data. Then if condition 2 is also met, tcp_recvmsg() often returns all the copied out data successfully without actually consuming the skb, due to a check "if ((chunk = len - tp->ucopy.len) != 0) {" and "len -= chunk;" after tcp_prequeue_process() that causes "len" to become 0 and an early exit from the big while loop. I don't see any reason not to free the skb whose data have been fully consumed in tcp_data_queue(), regardless of the FIN flag. We won't get there if MSG_PEEK is on. Am I missing some arcane cases related to urgent data? Signed-off-by: H.K. Jerry Chu <hkchu@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-01-25mac80211: fix a crash in ieee80211_beacon_get_tim on change_interfaceFelix Fietkau
Some drivers (e.g. ath9k) do not always disable beacons when they're supposed to. When an interface is changed using the change_interface op, the mode specific sdata part is in an undefined state and trying to get a beacon at this point can produce weird crashes. To fix this, add a check for ieee80211_sdata_running before using anything from the sdata. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Signed-off-by: John W.

2011-01-25ALSA: AACI: fix timeout durationRussell King
Relying on the access time of peripherals is unreliable - it depends on the speed of the CPU and the bus. On Versatile Express, these timeouts were expiring, causing the driver to fail. Add udelay(1) to ensure that they don't expire early, and adjust timeouts to give a reasonable margin over the response times. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-01-25ARM: 6636/1: ep93xx: default multiplexed gpio ports to gpio modeHartley Sweeten
The EP93xx C and D GPIO ports are multiplexed with the Keypad Interface peripheral.  At power-up they default into non-GPIO mode with the Key Matrix controller enabled so these ports are unusable for GPIO.  Note that the Keypad Interface peripheral is only available in the EP9307, EP9312, and EP9315 processor variants. The keypad support will clear the DeviceConfig bits appropriately to enable the Keypad Interface when the driver is loaded.  And, when the driver is unloaded it will set the bits to return the ports to GPIO mode. To make these ports available for GPIO after power-up on all EP93xx processor variants, set the KEYS and GONK bits in the DeviceConfig register. Similarly, the E, G, and H ports are multiplexed with the IDE Interface peripheral.  At power-up these also default into non-GPIO mode.  Note that the IDE peripheral is only available in the EP9312 and EP9315 processor variants. Since an IDE driver is not even available in mainline, set the EONIDE, GONIDE, and HONIDE bits in the DeviceConfig register so that these ports will be available for GPIO use after power-up.

2011-01-25PM / Runtime: Don't enable interrupts while running in_interruptAlan Stern
This patch (as1445) fixes a bug in the runtime PM core left over from the addition of the no_callbacks flag. If this flag is set then it is possible for rpm_suspend() to be called in_interrupt, so when releasing spinlocks it's important not to re-enable interrupts. To avoid an unnecessary save-and-restore of the interrupt flag, the patch also inlines a pm_request_idle() call. This fixes Bugzilla #27482. (The offending code was added in 2.6.37, so it's not necessary to apply this to any earlier stable kernels.)

2011-01-25ARM: 6635/2: Configure reference clock for Versatile Express timersPawel Moll
Timers on Versatile Express mainboard are used as system clock/event sources. Driver assumes that they are clocked with 1MHz signal. Old V2M firmware apparently configured it by default, but on newer boards one can observe that "sleep 1" command takes over 30 seconds to finish, as the timers are fed with 32kHz instead... This patch performs required magic and also removes code clearing timer's control registers, as exactly the same operations are performed by the timer driver few jiffies later.

I haven't significantly updated the descriptions for the tiles as that is even less clear - as far as I can see on ARMs website, there is no Cortex-A9 tile for Realview EB - only ARM11MPCore, ARM1156T2F-S, ARM1176TZF-S and Cortex-R4F.

2011-01-24GRO: fix merging a paged skb after non-paged skbsMichal Schmidt
Suppose that several linear skbs of the same flow were received by GRO. They were thus merged into one skb with a frag_list. Then a new skb of the same flow arrives, but it is a paged skb with data starting in its frags[]. Before adding the skb to the frag_list skb_gro_receive() will of course adjust the skb to throw away the headers. It correctly modifies the page_offset and size of the frag, but it leaves incorrect information in the skb: ->data_len is not decreased at all. ->len is decreased only by headlen, as if no change were done to the frag. Later in a receiving process this causes skb_copy_datagram_iovec() to return -EFAULT and this is seen in userspace as the result of the recv() syscall. In practice the bug can be reproduced with the sfc driver. By default the driver uses an adaptive scheme when it switches between using napi_gro_receive() (with skbs) and napi_gro_frags() (with pages). The bug is reproduced when under rx load with enough successful GRO merging the driver decides to switch from the former to the latter. Manual control is also possible, so reproducing this is easy with netcat: - on machine1 (with sfc): nc -l 12345 > /dev/null - on machine2: nc machine1 12345 < /dev/zero - on machine1: echo 1 > /sys/module/sfc/parameters/rx_alloc_method # use skbs echo 2 > /sys/module/sfc/parameters/rx_alloc_method # use pages - See that nc has quit suddenly.

2011-01-24x86-64: Don't use pointer to out-of-scope variable in dump_trace()Jesper Juhl
In arch/x86/kernel/dumpstack_64.c::dump_trace() we have this code: ... if (!stack) { unsigned long dummy; stack = &dummy; if (task && task != current) stack = (unsigned long *)task->thread.sp; } bp = stack_frame(task, regs); /* * Print function call entries in all stacks, starting at the * current stack address. If the stacks consist of nested * exceptions */ tinfo = task_thread_info(task); for (;;) { char *id; unsigned long *estack_end; estack_end = in_exception_stack(cpu, (unsigned long)stack, &used, &id); ... You'll notice that we assign to 'stack' the address of the variable 'dummy' which is only in-scope inside the 'if (!stack)'. So when we later access stack (at the end of the above, and assuming we did not take the 'if (task && task != current)' branch) we'll be using the address of a variable that is no longer in scope. I believe this patch is the proper fix, but I freely admit that I'm not 100% certain.

Fix a shutdown regression caused by 2a2d31c8dc6f ("intel_idle: open broadcast clock event"). The clockevent framework can automatically shutdown broadcast timers for hotremove CPUs. And we get a shutdown regression when we shutdown broadcast timer for hot remove CPU, so just delete some code. Also fix some section mismatch.
