2008-10-23[PATCH] hpfs: cleanup ->setattrChristoph Hellwig
Reformat hpfs_notify_change to standard kernel style to make it readable and rename it to hpfs_setattr as that's what the method is called. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2008-10-23[PATCH] get rid of path_lookup_create()Al Viro
... and don't pass bogus flags when we are just looking for parent. Fold __path_lookup_intent_open() into path_lookup_open() while we are at it; that's the only remaining caller. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2008-10-23net: Fix disjunct computation of netdev featuresHerbert Xu
My change commit e2a6b85247aacc52d6ba0d9b37a99b8d1a3e0d83 net: Enable TSO if supported by at least one device didn't do what was intended because the netdev_compute_features function was designed for conjunctions. So what happened was that it would simply take the TSO status of the last constituent device. This patch extends it to support both conjunctions and disjunctions under the new name of netdev_increment_features. It also adds a new function netdev_fix_features which does the sanity checking that usually occurs upon registration. This ensures that the computation doesn't result in an illegal combination since this checking is absent when the change is initiated via ethtool. The two users of netdev_compute_features have been converted. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-10-23sctp: Fix to handle SHUTDOWN in SHUTDOWN_RECEIVED stateWei Yongjun
Once an endpoint has reached the SHUTDOWN-RECEIVED state, it MUST NOT send a SHUTDOWN in response to a ULP request. The Cumulative TSN Ack of the received SHUTDOWN chunk MUST be processed. This patch fix to process Cumulative TSN Ack of the received SHUTDOWN chunk in SHUTDOWN_RECEIVED state.

2008-10-23sctp: Fix to handle SHUTDOWN in SHUTDOWN-PENDING stateWei Yongjun
If SHUTDOWN is received in SHUTDOWN-PENDING state, enpoint should enter the SHUTDOWN-RECEIVED state and check the Cumulative TSN Ack field of the SHUTDOWN chunk (RFC 4960 Section 9.2). If the SHUTDOWN chunk can acknowledge all of the send DATA chunks, SHUTDOWN-ACK should be sent. But now endpoint just silently discarded the SHUTDOWN chunk. SHUTDOWN received in SHUTDOWN-PENDING state can happend when the last SACK is lost by network, or the SHUTDOWN chunk can acknowledge all of the received DATA chunks. The packet sequence(SACK lost) is like this: Endpoint A Endpoint B ULP (ESTABLISHED) (ESTABLISHED) <----------- DATA <--- shutdown Enter SHUTDOWN-PENDING state SACK ----lost----> SHUTDOWN(*1) ------------> <----------- SHUTDOWN-ACK (*1) silently discarded now. This patch fix to handle SHUTDOWN in SHUTDOWN-PENDING state as the same as ESTABLISHED state.

2008-10-23sctp: Add check for the TSN field of the SHUTDOWN chunkWei Yongjun
If SHUTDOWN chunk is received Cumulative TSN Ack beyond the max tsn currently send, SHUTDOWN chunk be accepted and the association will be broken. New data is send, but after received SACK it will be drop because TSN in SACK is less than the Cumulative TSN, data will be retrans again and again even if correct SACK is received. The packet sequence is like this: Endpoint A Endpoint B ULP (ESTABLISHED) (ESTABLISHED) <----------- DATA (TSN=x-1) <----------- DATA (TSN=x) SHUTDOWN -----------> (Now Cumulative TSN=x+1000) (TSN=x+1000) <----------- DATA (TSN=x+1) SACK -----------> drop the SACK (TSN=x+1) <----------- DATA (TSN=x+1)(retrans) This patch fix this problem by terminating the association and respond to the sender with an ABORT.

2008-10-23sctp: Drop ICMP packet too big message with MTU larger than current PMTUWei Yongjun
If ICMP packet too big message is received with MTU larger than current PMTU, SCTP will still accept this ICMP message and sync the PMTU of assoc with the wrong MTU. Endpoing A Endpoint B (ESTABLISHED) (ESTABLISHED) ICMP ---------> (packet too big, MTU too larger) sync PMTU This patch fixed the problem by drop that ICMP message.

2008-10-23x86: drop double underscores from header guardsH. Peter Anvin
Drop double underscores from header guards in arch/x86/include. They are used inconsistently, and are not necessary. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2008-10-22x86: Fix ASM_X86__ header guardsH. Peter Anvin

a) the only difference between sigcontext and sysdep/sigcontext is that the former contains externs for two long-dead functions.

2008-10-22math-emu: Fix thinko in _FP_DIVDavid S. Miller
In commit 48d6c64311ddb6417b901639530ccbc47bdc7635 ("math-emu: Add support for reporting exact invalid exception") code was added to set the new FP_EX_INVALID_{IDI,ZDZ} exception flag bits. However there is a missing break statement for the _FP_CLS_COMBINE(FP_CLS_INF,FP_CLS_INF) switch case, the code just falls into _FP_CLS_COMBINE(FP_CLS_ZERO,FP_CLS_ZERO) which then proceeds to overwrite all of the settings. Fix by adding the missing break. Signed-off-by: David S. Miller <davem@davemloft.net>
