* [TCP]: continued: reno sacked_out count fixAki M Nyrhinen2006-06-111-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Aki M Nyrhinen <anyrhine@cs.helsinki.fi> IMHO the current fix to the problem (in_flight underflow in reno) is incorrect. it treats the symptons but ignores the problem. the problem is timing out packets other than the head packet when we don't have sack. i try to explain (sorry if explaining the obvious). with sack, scanning the retransmit queue for timed out packets is fine because we know which packets in our retransmit queue have been acked by the receiver. without sack, we know only how many packets in our retransmit queue the receiver has acknowledged, but no idea which packets. think of a "typical" slow-start overshoot case, where for example every third packet in a window get lost because a router buffer gets full. with sack, we check for timeouts on those every third packet (as the rest have been sacked). the packet counting works out and if there is no reordering, we'll retransmit exactly the packets that were lost. without sack, however, we check for timeout on every packet and end up retransmitting consecutive packets in the retransmit queue. in our slow-start example, 2/3 of those retransmissions are unnecessary. these unnecessary retransmissions eat the congestion window and evetually prevent fast recovery from continuing, if enough packets were lost.

* [PATCH] Fix for the PPTP hangs that have been reportedPaul Mackerras2006-06-111-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | People have been reporting that PPP connections over ptys, such as used with PPTP, will hang randomly when transferring large amounts of data, for instance in http://bugzilla.kernel.org/show_bug.cgi?id=6530. I have managed to reproduce the problem, and the patch below fixes the actual cause. The problem is not in fact in ppp_async.c but in n_tty.c. What happens is that when pptp reads from the pty, we call read_chan() in drivers/char/n_tty.c on the master side of the pty. That copies all the characters out of its buffer to userspace and then calls check_unthrottle(), which calls the pty unthrottle routine, which calls tty_wakeup on the slave side, which calls ppp_asynctty_wakeup, which calls tasklet_schedule. So far so good. Since we are in process context, the tasklet runs immediately and calls ppp_async_process(), which calls ppp_async_push, which calls the tty->driver->write function to send some more output. However, tty->driver->write() returns zero, because the master tty->receive_room is still zero. We haven't returned from check_unthrottle() yet, and read_chan() only updates tty->receive_room _after_ calling check_unthrottle. That means that the driver->write call in ppp_async_process() returns 0. That would be fine if we were going to get a subsequent wakeup call, but we aren't (we just had it, and the buffer is now empty). The solution is for n_tty.c to update tty->receive_room _before_ calling the driver unthrottle routine. The patch below does this. With this patch I was able to transfer a 900MB file over a PPTP connection (taking about 25 minutes), whereas without the patch the connection would always stall in under a minute.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to Intel ICH spec, there are several rules that Base Address should be programmed before IOSE (PCICMD register ) enabled. For example ICH7: 12.1.3 SATA : the base address register for the bus master register should be programmed before this bit is set. 11.1.3: PCICMD (USB): The base address register for USB should be programmed before this bit is set. .... To make sure kernel code follow this rule , and prevent unnecessary confusion. I proposal this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently don't handle errors properly when resuming a PCI device: * In pci_default_resume() we capture the error code returned by pci_enable_device() but don't pass it up to the caller.

* | [PATCH] Further alterations for memory barrier documentDavid Howells2006-06-101-78/+270

The following changes were made: (*) One of the examples given for what can happen with overlapping memory barriers was wrong. (*) The description of general memory barriers said that a general barrier is a combination of a read barrier and a write barrier. This isn't entirely true: it implies both, but is more than a combination of both. (*) The first example in the "SMP Barrier Pairing" section was wrong: the loads around the read barrier need to touch the memory locations in the opposite order to the stores around the write barrier. (*) Added a note to make explicit that the loads should be in reverse order to the stores. (*) Adjusted the diagrams in the "Examples Of Memory Barrier Sequences" section to make them clearer. Added a couple of diagrams to make it more clear as to how it could go wrong without the barrier. (*) Added a section on memory speculation. (*) Dropped any references to memory allocation routines doing memory barriers. They may do sometimes, but it can't be relied on. This may be worthy of further documentation later. (*) Made the fact that a LOCK followed by an UNLOCK should not be considered a full memory barrier more explicit and gave an example.

To fix this, we need to maintain the queue lock for a bit longer. Unfortunately we cannot do that, since the elevator init requires to be run without the lock held. This isn't easily fixable, without also changing the mempool API. So split the initialization into two parts, and alloc-init operation and an attach operation. Then we can preallocate the io scheduler and related structures, and run the attach inside the lock after we detach the old one.

|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: "Andy Currid" <ACurrid@nvidia.com> This patch fixes a kernel panic during boot that occurs on NVIDIA platforms that have HPET enabled. When HPET is enabled, the standard timer IRQ is routed to IOAPIC pin 2 and is advertised as such in the ACPI APIC table - but an earlier workaround in the kernel was ignoring this override. The fix is to honor timer IRQ overrides from ACPI when HPET is detected on an NVIDIA platform.

Since the length is entirely arbitrary for a FIN packet carrying data, this is actually quite common. Unaligned data is not the end of the world, but we should avoid it if it's easily done. In this case it is trivial. Since we're discarding all of the head data it doesn't matter whether we move skb->data forward or back. However, it is still possible to have unaligned skb->data in general. So network drivers should be prepared to handle it instead of crashing. This patch also adds an unlikely marking on len < headlen since partial ACKs on head data are extremely rare in the wild. As the return value of __pskb_trim_head is no longer ever NULL that has been removed. Signed-off-by: Herbert Xu ~{PmV>HI~} <herbert@gondor.apana.org.au> Signed-off-by: David S.
