| * xfrm: do not leak ESRCH to user spacefernando@oss.ntt.co2008-10-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed that, under certain conditions, ESRCH can be leaked from the xfrm layer to user space through sys_connect. In particular, this seems to happen reliably when the kernel fails to resolve a template either because the AF_KEY receive buffer being used by racoon is full or because the SA entry we are trying to use is in XFRM_STATE_EXPIRED state. However, since this could be a transient issue it could be argued that EAGAIN would be more appropriate. Besides this error code is not even documented in the man page for sys_connect (as of man-pages 3.07). Signed-off-by: Fernando Luis Vazquez Cao <fernando@oss.ntt.co.jp> Signed-off-by: David S.

* | | saner FASYNC handling on file closeAl Viro2008-11-01
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

| * tcp: Restore ordering of TCP options for the sake of inter-operabilityIlpo Järvinen2008-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is not our bug! Sadly some devices cannot cope with the change of TCP option ordering which was a result of the recent rewrite of the option code (not that there was some particular reason steming from the rewrite for the reordering) though any ordering of TCP options is perfectly legal. Thus we restore the original ordering to allow interoperability with/through such broken devices and add some warning about this trap. Since the reordering just happened without any particular reason, this change shouldn't cost us anything. There are already couple of known failure reports (within close proximity of the last release), so the problem might be more wide-spread than a single device. And other reports which may be due to the same problem though the symptoms were less obvious. Analysis of one of the case revealed (with very high probability) that sack capability cannot be negotiated as the first option (SYN never got a response).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.

| * tcp: should use number of sack blocks instead of -1Ilpo Järvinen2008-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While looking for the recent "sack issue" I also read all eff_sacks usage that was played around by some relevant commit. I found out that there's another thing that is asking for a fix (unrelated to the "sack issue" though). This feature has probably very little significance in practice. Opposite direction timeout with bidirectional tcp comes to me as the most likely scenario though there might be other cases as well related to non-data segments we send (e.g., response to the opposite direction segment). Also some ACK losses or option space wasted for other purposes is necessary to prevent the earlier SACK feedback getting to the sender.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the reorganization some of the multi-theaded locking assumptions were accidently relaxed. This patch moves us back towards a more conservative locking strategy. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we get an error on parsing a stat due to a protocol bug, we can generate an oops during cleanup because we didn't initialize the string pointers in the stat structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the current debug options allows users to get a verbose dump of fcalls. This isn't really necessary as correctly parsed protocol frames can be printed as part of the code in the client functions. The consolidated printfcalls structure would require new entries to be added for every extension. This patch removes the debug print methods and their use.

| * | | 9p: add new protocol support codeEric Van Hensbergen2008-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new protocol processing support code based on Anthony Liguori's 9p library code. This code performs protocol marshalling/unmarshalling using printf like strings to represent protocol elements. It is my intent to use them to replace the current functions in conv.c as well as the p9_create_* functions. This should make the client implementation much more clear, and also make it much easier to add new protocol extensions by limiting the number of places in which changes need to be made.

Tversion is an exception as its encapsulated into the client_create code. This patch moves the protocol specifics of this to a function to match the rest of the code.
