b24b8a247f [NET]: Convert init_timer into setup_timer
Many-many code in the kernel initialized the timer->function
and  timer->data together with calling init_timer(timer). There
is already a helper for this. Use it for networking code.

The patch is HUGE, but makes the code 130 lines shorter
(98 insertions(+), 228 deletions(-)).

50e1092b3a SUNRPC xprtrdma: fix XDR tail buf marshalling for all ops
rpcrdma_convert_iovs is passed an xdr_buf representing either an RPC
request or an RPC reply. In the case of a request, several
calculations and tests involving pos are unnecessary. In the case of a
reply, several calculations and tests involving pos are incorrect (the
code tests pos against the reply xdr buf's len field, which is always
0 at the time rpcrdma_convert_iovs is executed). This change removes
the incorrect/unnecessary calculations and tests involving pos.

This fixes an observed problem when reading certain file sizes over
NFS/RDMA.

ffc40f5692 sunrpc: gss_pipe_downcall(), don't assume all errors are transient
Instead of mapping all errors except EACCES to EAGAIN, map all errors
except EAGAIN to EACCES.

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.

c46f2334c8 [SG] Get rid of __sg_mark_end()
sg_mark_end() overwrites the page_link information, but all users want
__sg_mark_end() behaviour where we just set the end bit. That is the most
natural way to use the sg list, since you'll fill it in and then mark the
end point.

So change sg_mark_end() to only set the termination bit. Add a sg_magic
debug check as well, and clear a chain pointer if it is set.

51c739d1f4 [NET]: Fix incorrect sg_mark_end() calls.
This fixes scatterlist corruptions added by

	commit 68e3f5dd4d
	[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

457c4cbc5a [NET]: Make /proc/net per network namespace
This patch makes /proc/net per network namespace.  It modifies the global
variables proc_net and proc_net_stat to be per network namespace.
The proc_net file helpers are modified to take a network namespace argument,
and all of their callers are fixed to pass &init_net for that argument.
This ensures that all of the /proc/net files are only visible and
usable in the initial network namespace until the code behind them
has been updated to be handle multiple network namespaces.

Making /proc/net per namespace is necessary as at least some files
in /proc/net depend upon the set of network devices which is per
network namespace, and even more files in /proc/net have contents
that are relevant to a single network namespace.

354ecbb9dd knfsd: Add source address to sunrpc svc errors
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.

calculations.  Both xdr_buf.len and iov.iov_len are size_t, which is
unsigned; so use an unsigned type for our temporary length variable to
ensure we don't overflow it..

afde94f398 SUNRPC: Fix default hostname created in rpc_create()
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.

bf19aacecb nfs: add server port to rpc_pipe info file
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.

Thanks to Olga Kornievskaia for testing and for an earlier
implementation.

1321d8d971 SUNRPC: Fix bytes-per-op accounting for RPC over UDP
NFS performance metrics reported zero bytes sent per op when mounting with
UDP.  The UDP socket transport wasn't properly counting the number of bytes
sent.
