Chuck Lever 081d53fe0b NFSD: Change the way the expected length of a fattr4 is checked
Because the fattr4 is now managed in an xdr_stream, all that is
needed is to store the initial position of the stream before
decoding the attribute list. Then the actual length of the list
is computed using the final stream position, after decoding is
complete.

No behavior change is expected.

Chuck Lever c1346a1216 NFSD: Replace the internals of the READ_BUF() macro
Convert the READ_BUF macro in nfs4xdr.c from open code to instead
use the new xdr_stream-style decoders already in use by the encode
side (and by the in-kernel NFS client implementation). Once this
conversion is done, each individual NFSv4 argument decoder can be
independently cleaned up to replace these macros with C code.

Chuck Lever 5191955d6f SUNRPC: Prepare for xdr_stream-style decoding on the server-side
A "permanent" struct xdr_stream is allocated in struct svc_rqst so
that it is usable by all server-side decoders. A per-rqst scratch
buffer is also allocated to handle decoding XDR data items that
cross page boundaries.

To demonstrate how it will be used, add the first call site for the
new svcxdr_init_decode() API.

As an additional part of the overall conversion, add symbolic
constants for successful and failed XDR operations. Returning "0" is
overloaded. Sometimes it means something failed, but sometimes it
means success. To make it more clear when XDR decoding functions
succeed or fail, introduce symbolic constants.

Chuck Lever d7cc739726 svcrdma: support multiple Read chunks per RPC
An efficient way to handle multiple Read chunks is to post them all
together and then take a single completion. This is also how the
code is already structured: when the Read completion fires, all
portions of the incoming RPC message are available to be assembled.

The difficult problem is setting up the Read sink buffers so that
the server pulls the client's data into place, making subsequent
pull-up unnecessary. There are several cases:

* No Read chunks. No-op.

* One data item Read chunk. This is the fast case, where the inline
  part of the RPC-over-RDMA message becomes the head and tail, and
  the data item chunk is placed in buf->pages.

* A Position-zero Read chunk. Treated like TCP: the Read chunk is
  pulled into contiguous pages.

+ A Position-zero Read chunk with data item chunks. Treated like
  TCP: all of the Read chunks are pulled into contiguous pages.

+ Multiple data item chunks. Treated like TCP: the inline part is
  copied and the data item chunks are pulled into contiguous pages.

The "*" cases are already supported. This patch adds support for the
"+" cases.

Chuck Lever 78147ca8b4 svcrdma: Add a "parsed chunk list" data structure
This simple data structure binds the location of each data payload
inside of an RPC message to the chunk that will be used to push it
to or pull it from the client.

There are several benefits to this small additional overhead:

 * It enables support for more than one chunk in incoming Read and
   Write lists.

 * It translates the version-specific on-the-wire format into a
   generic in-memory structure, enabling support for multiple
   versions of the RPC/RDMA transport protocol.

 * It enables the server to re-organize a chunk list if it needs to
   adjust where Read chunk data lands in server memory without
   altering the contents of the XDR-encoded Receive buffer.

Construction of these lists is done while sanity checking each
incoming RPC/RDMA header. Subsequent patches will make use of the
generated data structures.

Chuck Lever f6ad77590a svcrdma: Post RDMA Writes while XDR encoding replies
The only RPC/RDMA ordering requirement between RDMA Writes and RDMA
Sends is that the responder must post the Writes on the Send queue
before posting the Send that conveys the RPC Reply for that Write
payload.

The Linux NFS server implementation now has a transport method that
can post result Payload Writes earlier than svc_rdma_sendto:

   ->xpo_result_payload()

This gets RDMA Writes going earlier so they are more likely to be
complete at the remote end before the Send completes.

Some care must be taken with pulled-up Replies. We don't want to
push the Write chunk and then send the same payload data via Send.

Linus Torvalds aae5ab854e RISC-V Fixes for 5.10-rc6
I've collected a handful of fixes over the past few weeks:
 
 * A fix to un-break the build-id argument to the vDSO build, which is necessary
   for the LLVM linker.
 * A fix to initialize the jump label subsystem, without which it (and all the
   stuff that uses it) doesn't actually function.
 * A fix to include <asm/barrier.h> from <vdso/processor.h>, without which some
   drivers won't compile.
 
 I know it's the holidays, but I had some hiccups getting this tested earlier
 this week so it's just going out now.  None of these are tremendously urgent,
 so if they don't make rc6 it's not a big deal.  I'll have some more fixes
 coming next week either way.

Linus Torvalds ca579827c9 perf tools for v5.10: 4th batch
- Fix die_entrypc() when DW_AT_ranges DWARF attribute not available.
 
 - Cope with broken DWARF (missing DW_AT_declaration) generated by some recent
   gcc versions.
 
 - Do not generate CGROUP metadata events when not asked to in 'perf record'.
 
 - Use proper CPU for shadow stats in 'perf stat'.
 
 - Update copy of libbpf's hashmap.c, silencing tools/perf build warning.
 
 - Fix return value in 'perf diff'.
 
 Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
 
 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.
