prepare_reply_buffer() and its NFSv4 equivalents expose the details of the RPC header and the auth slack values to upper layer consumers, creating a layering violation, and duplicating code. Remedy these issues by adding a new RPC client API that hides those details from upper layers in a common helper function. Signed-off-by:

The key action of xdr_buf_trim() is that it shortens buf->len, the length of the xdr_buf's content. The other actions -- shortening the head, pages, and tail components -- are actually not necessary. In particular, changing the size of those components can corrupt the RPC message contained in the buffer. This is an accident waiting to happen rather than a current bug, as far as we know.

- Recover some instruction count because I'm about to introduce a few xdr_inline_decode call sites - Replace dprintk() call sites with trace points - Reduce the hot path so it fits in fewer cachelines I've also renamed it rpc_decode_header() to match everything else in the RPC client.

Enable distributions to enforce the rejection of ancient and insecure Kerberos enctypes in the kernel's RPCSEC_GSS implementation. These are the single-DES encryption types that were deprecated in 2012 by RFC 6649. Enctypes that were deprecated more recently (by RFC 8429) remain fully supported for now because they are still likely to be widely used. Signed-off-by:

tsh_size was added to accommodate transports that send a pre-amble before each RPC message. However, this assumes the pre-amble is fixed in size, which isn't true for some transports. That makes tsh_size not very generic. Also I'd like to make the estimation of RPC send and receive buffer sizes more precise. tsh_size doesn't currently appear to be accounted for at all by call_allocate. Therefore let's just remove the tsh_size concept, and make the only transports that have a non-zero tsh_size employ a direct approach. Signed-off-by:

We don't want READ payloads that are partially in the head iovec and in the page buffer because this requires pull-up, which can be expensive. The NFS/RPC client tries hard to predict the size of the head iovec so that the incoming READ data payload lands only in the page vector, but it doesn't always get it right. To help diagnose such problems, add a trace point in the logic that decodes READ-like operations that reports whether pull-up is being done. Signed-off-by:

In very rare cases, an NFS READ operation might predict that the non-payload part of the RPC Call is large. For instance, an NFSv4 COMPOUND with a large GETATTR result, in combination with a large Kerberos credential, could push the non-payload part to be several kilobytes. If the non-payload part is larger than the connection's inline threshold, the client is required to provision a Reply chunk. The current Linux client does not check for this case. There are two obvious ways to handle it: a. Provision a Write chunk for the payload and a Reply chunk for the non-payload part b. Provision a Reply chunk for the whole RPC Reply Some testing at a recent NFS bake-a-thon showed that servers can mostly handle a. but there are some corner cases that do not work yet. b. already works (it has to, to handle krb5i/p), but could be somewhat less efficient. However, I expect this scenario to be very rare -- no-one has reported a problem yet. So I'm going to implement b. Sometime later I will provide some patches to help make b. a little more efficient by more carefully choosing the Reply chunk's segment sizes to ensure the payload is optimally aligned.

set_pmd_at() calls native_set_pmd() unconditionally on x86. This was fine as long as only huge page entries were written via set_pmd_at(), as Xen pv guests don't support those. Commit 2c91bd4a ("mm: speed up mremap by 20x on large regions") introduced a usage of set_pmd_at() possible on pv guests, leading to failures like: BUG: unable to handle kernel paging request at ffff888023e26778 #PF error: [PROT] [WRITE] RIP: e030:move_page_tables+0x7c1/0xae0 move_vma.isra.3+0xd1/0x2d0 __se_sys_mremap+0x3c6/0x5b0 do_syscall_64+0x49/0x100 entry_SYSCALL_64_after_hwframe+0x44/0xa9 Make set_pmd_at() paravirt aware by just letting it use set_pmd().
