2006-12-13[PATCH] knfsd: nfsd: don't drop silently on upcall deferralJ.Bruce Fields
To avoid tying up server threads when nfsd makes an upcall (to mountd, to get export options, to idmapd, for nfsv4 name<->id mapping, etc.), we temporarily "drop" the request and save enough information so that we can revisit it later. Certain failures during the deferral process can cause us to really drop the request and never revisit it. This is often less than ideal, and is unacceptable in the NFSv4 case--rfc 3530 forbids the server from dropping a request without also closing the connection. As a first step, we modify the deferral code to return -ETIMEDOUT (which is translated to nfserr_jukebox in the v3 and v4 cases, and remains a drop in the v2 case). Signed-off-by: J.

2006-12-06rpcgss: krb5: sanity check sealalg value in the downcallJ. Bruce Fields
The sealalg is checked in several places, giving the impression it could be either SEAL_ALG_NONE or SEAL_ALG_DES. But in fact SEAL_ALG_NONE seems to be sufficient only for making mic's, and all the contexts we get must be capable of wrapping as well. So the sealalg must be SEAL_ALG_DES. As with signalg, just check for the right value on the downcall and ignore it otherwise. Similarly, tighten expectations for the sealalg on incoming tokens, in case we do support other values eventually. Signed-off-by: J.

2006-12-06gss: krb5: remove signalg and sealalgJ. Bruce Fields
We designed the krb5 context import without completely understanding the context. Now it's clear that there are a number of fields that we ignore, or that we depend on having one single value. In particular, we only support one value of signalg currently; so let's check the signalg field in the downcall (in case we decide there's something else we could support here eventually), but ignore it otherwise.

2006-12-06rpc: spkm3 updateOlga Kornievskaia
This updates the spkm3 code to bring it up to date with our current understanding of the spkm3 spec. In doing so, we're changing the downcall format used by gssd in the spkm3 case, which will cause an incompatilibity with old userland spkm3 support. Since the old code a) didn't implement the protocol correctly, and b) was never distributed except in the form of some experimental patches from the citi web site, we're assuming this is OK. We do detect the old downcall format and print warning (and fail). We also include a version number in the new downcall format, to be used in the future in case any further change is required. In some more detail: - fix integrity support - removed dependency on NIDs. instead OIDs are used - known OID values for algorithms added. - fixed some context fields and types Signed-off-by: J.

This code is never called from interrupt context; it's always run by either a user thread or rpciod. So KM_SKB_SUNRPC_DATA is inappropriate here. Thanks to Aimé Le Rouzic for capturing an oops which showed the kernel taking an interrupt while we were in this piece of code, resulting in a nested kmap_atomic(.,KM_SKB_SUNRPC_DATA) call from xdr_partial_copy_from_skb().

2006-10-04[PATCH] knfsd: Replace two page lists in struct svc_rqst with oneNeilBrown
We are planning to increase RPCSVC_MAXPAGES from about 8 to about 256. This means we need to be a bit careful about arrays of size RPCSVC_MAXPAGES. struct svc_rqst contains two such arrays. However the there are never more that RPCSVC_MAXPAGES pages in the two arrays together, so only one array is needed. The two arrays are for the pages holding the request, and the pages holding the reply. Instead of two arrays, we can simply keep an index into where the first reply page is. This patch also removes a number of small inline functions that probably server to obscure what is going on rather than clarify it, and opencode the needed functionality. Also remove the 'rq_restailpage' variable as it is *always* 0. i.e. if the response 'xdr' structure has a non-empty tail it is always in the same pages as the head. check counters are initilised and incr properly check for consistant usage of ++ etc maybe extra some inlines for common approach general review Signed-off-by: Neil Brown <neilb@suse.de> Cc: Magnus Maatta <novell@kiruna.se> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
