2007-10-10[MAC80211]: move some rate control functions out of ieee80211.cJohannes Berg
I think these can go with rate control just as well and it makes ieee80211.c more readable. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2007-10-10[MAC80211]: split out some key functions from ieee80211.cJohannes Berg

2007-10-10[MAC80211]: fix bug for per-sta statsJohannes Berg

2007-10-10[MAC80211]: split up __ieee80211_rxJohannes Berg
The really indented part that does the huge switch on the interface type is a nuisance. Put it into an own function 'prepare_for_handlers'. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2007-10-10[MAC80211]: split ieee80211_rx_h_check handlerJohannes Berg
The ieee80211_rx_h_check handler really does two things, it's a lot easier to understand if it's split into ieee80211_rx_h_check and ieee80211_rx_h_load_key, and it may be possible in the future to optimise the key loading to not do it for each interface.

2007-10-09knfsd: Add source address to sunrpc svc errorsDr. David Alan Gilbert
This patch adds the address of the client that caused an error in sunrpc/svc.c so that you get errors that look like: svc: 192.168.66.28, port=709: unknown version (3 for prog 100003, nfsd) I've seen machines which get bunches of unknown version or similar errors from time to time, and while the recent patch to add the service helps to find which service has the wrong version it doesn't help find the potentially bad client. The patch is against a checkout of Linus's git tree made on 2007-08-24. One observation is that the svc_print_addr function prints to a buffer which in this case makes life a little more complex; it just feels as if there must be lots of places that print a connection address - is there a better function to use anywhere? I think actually there are a few places with semi duplicated code; e.g. one_sock_name switches on the address family but only currently has IPV4; I wonder how many other places are similar.

2007-10-09svcgss: move init code into separate functionJ. Bruce Fields
We've let svcauth_gss_accept() get much too long and hairy. The RPC_GSS_PROC_INIT and RPC_GSS_PROC_CONTINUE_INIT cases share very little with the other cases, so it's very natural to split them off into a separate function. This will also nicely isolate the piece of code we need to parametrize to authenticating gss-protected NFSv4 callbacks on behalf of the NFS client. Signed-off-by: J.

Use correct type signage in gss_krb5_remove_padding() when doing length calculations.

2007-10-09SUNRPC: Fix default hostname created in rpc_create()J. Bruce Fields
Since 43780b87fa7..., rpc_create() fills in a default hostname based on the ip address if the servername passed in is null. A small typo made that default incorrect. (But this information appears to be used only for debugging right now, so I don't believe the typo causes any bugs in the current kernel.) Thanks to Olga Kornievskaia for bug report and testing.

2007-10-09nfs: add server port to rpc_pipe info fileJ. Bruce Fields
On the client, when an alternate server port is specified on the mount commandline, we need to make sure gssd knows about it. Also, on the server side, when we're sending krb5 callbacks to the client, we'll use the same mechanism to let gssd know about the callback port.

2007-10-09SUNRPC: Finish API to load RPC transport implementations dynamically\"Talpey, Thomas\
Allow RPC client transport implementations to be loaded as needed, or as they become available from distributors or third-party vendors.

2007-10-09SUNRPC: RPC bind failures should be permanent for NULL requestsChuck Lever
The purpose of an RPC ping (a NULL request) is to determine whether the remote end is operating and supports the RPC program and version of the request. If we do an RPC bind and the remote's rpcbind service says "this program or service isn't supported" then we have our answer already, and we should give up immediately. This is good for the kernel mount client, as it will cause the request to fail, and then allow an immediate retry with different options.

2007-10-09SUNRPC: Split another new rpcbind retry error code from EACCESChuck Lever
Add more new error code processing to the kernel's rpcbind client and to call_bind_status() to distinguish two cases: Case 1: the remote has replied that the program/version tuple is not registered (returns EACCES) Case 2: retry with a lesser rpcbind version (rpcb now returns EPFNOSUPPORT) This change allows more specific error processing for each of these two cases. We now fail case 2 instead of retrying... it's a server configuration error not to support even rpcbind version 2. And don't expose this new error code to user land -- convert it to EIO before failing the RPC.

2007-10-09SUNRPC: Add a new error code for retry waiting for another binderChuck Lever
Add new error code processing to the kernel's rpcbind client and to call_bind_status() to distinguish two cases: Case 1: the remote has replied that the program/version tuple is not registered (returns -EACCES) Case 2: another process is already in the middle of binding on this transport (now returns -EAGAIN) This change allows more specific retry processing for each of these two cases.

2007-10-09SUNRPC: Make rpcb_decode_getaddr more picky about universal addressesChuck Lever

2007-10-09SUNRPC: Use correct argument type in memcpy()Chuck Lever
Noticed by Tom Talpey <tmt@netapp.com>: OBTW, there's a nit on that memcpy, too. The r_addr is an array, so memcpy(&map->r_addr is passing the address of the array as a char **.

2007-10-09SUNRPC: Fix generation of universal addresses forChuck Lever
Fix some problems with rpcbind v3 and v4 queries from the in-kernel rpcbind client: 1. The r_addr argument must be a full universal address, not just an IP address, and 2. The universal address in r_addr is the address of the remote rpcbind server, not the RPC service being requested This addresses bugzilla.kernel.org report 8891 for 2.6.23-rc and greater. In addition, if the rpcbind client is unable to start the rpcbind request, make sure not to leak the xprt. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
