| * gss_krb5: create a define for token header size and clean up ptr locationKevin Coffman2008-06-233-46/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cleanup: Document token header size with a #define instead of open-coding it. Don't needlessly increment "ptr" past the beginning of the header which makes the values passed to functions more understandable and eliminates the need for extra "krb5_hdr" pointer. Clean up some intersecting white-space issues flagged by checkpatch.pl. This leaves the checksum length hard-coded at 8 for DES. A later patch cleans that up.

| | * SUNRPC: Don't change the RPCSEC_GSS context on a credential that is in useTrond Myklebust2008-04-191-27/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a server rejects our credential with an AUTH_REJECTEDCRED or similar, we need to refresh the credential and then retry the request. However, we do want to allow any requests that are in flight to finish executing, so that we can at least attempt to process the replies that depend on this instance of the credential. The solution is to ensure that gss_refresh() looks up an entirely new RPCSEC_GSS credential instead of attempting to create a context for the existing invalid credential.

| | | | | | | | | | | | | | | | | | | | | | | | | | | We need to try to ensure that we always use the same credentials whenever we re-establish the clientid on the server.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ..and always destroy using a 'soft' RPC call. Destroying GSS credentials isn't mandatory; the server can always cope with a few credentials not getting destroyed in a timely fashion. This actually fixes a hang situation. Basically, some servers will decide that the client is crazy if it tries to destroy an RPC context for which they have sent an RPCSEC_GSS_CREDPROBLEM, and so will refuse to talk to it for a while. The regression therefor probably was introduced by commit 0df7fb74fbb709591301871a38aac7735a1d6583. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | * SUNRPC: Run rpc timeout functions as callbacks instead of in softirqsTrond Myklebust2008-02-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An audit of the current RPC timeout functions shows that they don't really ever need to run in the softirq context. As long as the softirq is able to signal that the wakeup is due to a timeout (which it can do by setting task->tk_status to -ETIMEDOUT) then the callback functions can just run as standard task->tk_callback functions (in the rpciod/process context). The only possible border-line case would be xprt_timer() for the case of UDP, when the callback is used to reduce the size of the transport congestion window. In testing, however, the effect of moving that update to a callback would appear to be minor. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | g_make_token_header() and g_token_size() add two too many, and therefore their callers pass in "(logical_value - 2)" rather than "logical_value" as hard-coded values which causes confusion. This dates back to the original g_make_token_header which took an optional token type (token_id) value and added it to the token. This was removed, but the routine always adds room for the token_id rather than not. Signed-off-by: Kevin Coffman <kwc@citi.umich.edu> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>

An example is user-land negotiating a Kerberos context with an encryption type that is not supported by the kernel code. (This can happen due to mis-configuration or a bug in the Kerberos code that does not honor our request to limit the encryption types negotiated.) This failure is not transient, and returning EAGAIN causes mount to continuously retry rather than giving up.

| | | | | | | | | | | | sg_mark_end() overwrites the page_link information, but all users want __sg_mark_end() behaviour where we just set the end bit.

* [NET]: Fix incorrect sg_mark_end() calls.David S. Miller2007-10-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes scatterlist corruptions added by commit 68e3f5dd4db62619fdbe520d36c9ebf62e672256 [CRYPTO] users: Fix up scatterlist conversion errors The issue is that the code calls sg_mark_end() which clobbers the sg_page() pointer of the final scatterlist entry. The first part fo the fix makes skb_to_sgvec() do __sg_mark_end(). After considering all skb_to_sgvec() call sites the most correct solution is to call __sg_mark_end() in skb_to_sgvec() since that is what all of the callers would end up doing anyways. I suspect this might have fixed some problems in virtio_net which is the sole non-crypto user of skb_to_sgvec(). Other similar sg_mark_end() cases were converted over to __sg_mark_end() as well. Arguably sg_mark_end() is a poorly named function because it doesn't just "mark", it clears out the page pointer as a side effect, which is what led to these bugs in the first place. The one remaining plain sg_mark_end() call is in scsi_alloc_sgtable() and arguably it could be converted to __sg_mark_end() if only so that we can delete this confusing interface from linux/scatterlist.h Signed-off-by: David S.

* nfsd: fix possible oops on re-insertion of rpcsec_gss modulesJ. Bruce Fields2007-07-241-4/+5
| | | | | | | | | | | | | | | | | The handling of the re-registration case is wrong here; the "test" that was returned from auth_domain_lookup will not be used again, so that reference should be put. And auth_domain_lookup never did anything with "new" in this case, so we should just clean it up ourself. Thanks to Akinobu Mita for bug report, analysis, and testing.
