* Revert "e1000: fix NAPI performance on 4-port adapters"Linus Torvalds2007-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 60cba200f11b6f90f35634c5cd608773ae3721b7. It's been linked to lockups of the e1000 hardware, see for example https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=229603 but it's likely that the commit itself is not really introducing the bug, but just allowing an unrelated problem to rear its ugly head (ie one current working theory is that the code exposes us to a hardware race condition by decreasing the amount of time we spend in each NAPI poll cycle). We'll revert it until root cause is known. Intel has a repeatable reproduction on two different machines and bus traces of the hardware doing something bad.

By setting these appropriately, normal performance goes from 750Mbytes/sec to 940Mbytes/sec (non-jumbo).

* | spidernet: Fix problem sending IP fragmentsLinas Vepstas2007-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The basic structure of "normal" UDP/IP/Ethernet frames (that actually work): - It starts with the Ethernet header (dest MAC, src MAC, etc.) - The next part is occupied by the IP header (version info, length of packet, id=0, fragment offset=0, checksum, from / to address, etc.) - Then comes the UDP header (src / dest port, length, checksum) - Actual payload - Ethernet checksum Now what's different for IP fragment: - The IP header has id set to some value (same for all fragments), offset is set appropriately (i.e. 0 for first fragment, following according to size of other fragments), size is the length of the frame. - UDP header is unchanged. I.e. length is according to full UDP datagram, not just the part within the actual frame! But this is only true within the first frame: all following frames don't have a valid UDP-header at all. The spidernet silicon seems to be quite intelligent: It's able to compute (IP / UDP / Ethernet) checksums on the fly and tests if frames are conforming to RFC -- at least conforming to RFC on complete frames. But IP fragments are different as explained above: I.e. for IP fragments containing part of a UDP datagram it sees incompatible length in the headers for IP and UDP in the first frame and, thus, skips this frame. But the content *is* correct for IP fragments. For all following frames it finds (most probably) no valid UDP header at all. But this *is* also correct for IP fragments. The Linux IP-stack seems to be clever in this point. It expects the spidernet to calculate the checksum (since the module claims to be able to do so) and marks the skb's for "normal" frames accordingly (ip_summed set to CHECKSUM_HW). But for the IP fragments it does not expect the driver to be capable to handle the frames appropriately. Thus all checksums are allready computed. This is also flaged within the skb (ip_summed set to CHECKSUM_NONE). Unfortunately the spidernet driver ignores that hints. It tries to send the IP fragments of UDP datagrams as normal UDP/IP frames. Since they have different structure the silicon detects them the be not "well-formed" and skips them. The following one-liner against 2.6.21-rc2 changes this behavior. If the IP-stack claims to have done the checksumming, the driver should not try to checksum (and analyze) the frame but send it as is.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nonpae guest pdes are shadowed by two pae ptes, so we double the offset twice: once to account for the pte size difference, and once because we need to shadow pdes for a single guest pde. But when writing to the upper guest pde we also need to truncate the lower bits, otherwise the multiply shifts these bits into the pde index and causes an access to the wrong shadow pde. If we're at the end of the page (accessing the very last guest pde) we can even overflow into the next host page and oops. Signed-off-by: Avi Kivity <avi@qumranet.com>

* | | [IrDA]: Correctly handling socket errorOlaf Kirch2007-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an oops first reported in mid 2006 - see http://lkml.org/lkml/2006/8/29/358 The cause of this bug report is that when an error is signalled on the socket, irda_recvmsg_stream returns without removing a local wait_queue variable from the socket's sk_sleep queue. This causes havoc further down the road. In response to this problem, a patch was made that invoked sock_orphan on the socket when receiving a disconnect indication. This is not a good fix, as this sets sk_sleep to NULL, causing applications sleeping in recvmsg (and other places) to oops. This is against the latest net-2.6 and should be considered for -stable inclusion.

* | | [SCTP]: Do not interleave non-fragments when in partial deliveryVlad Yasevich2007-04-18

The only way to this is for a message to not be a fragment and be 'in order' or unorderd for a given stream. This will result in bypassing the reassembly/ordering queues where things live duing partial delivery, and the message will be delivered to the socket in the middle of partial delivery. This is a two-fold problem, in that: 1. the app now must check the stream-id and flags which it may not be doing. 2. this clearing partial delivery state from the association and results in ulp hanging. This patch is a band-aid over a much bigger problem in that we don't do stream interleave. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S.

This gets rid of the effect of adjust_key(), which makes sure that bits 3 and 23 of the key are equal when the Sinai throughput optimization is enabled, and so it may happen that an FMR will end up with bits 3 and 23 in the key being different. This causes data corruption, because when enabling the throughput optimization, the driver promises the HCA firmware that bits 3 and 23 of all memory keys will always be equal.

* | | Provide dummy devm_ioport_* if !HAS_IOPORTRussell King2007-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide an dummy implementation of devm_ioport_map() and devm_ioport_unmap() to allow drivers (eg, pata_platform) to build for platforms where CONFIG_NO_IOPORT is selected.

* | | knfsd: use a spinlock to protect sk_info_authunixNeilBrown2007-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sk_info_authunix is not being protected properly so the object that it points to can be cache_put twice, leading to corruption. We borrow svsk->sk_defer_lock to provide the protection. We should probably rename that lock to have a more generic name - later. Thanks to Gabriel for reporting this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It got its lock and unlock backwards.

* | | ufs proper handling of zero link caseEvgeniy Dushistov2007-04-17
