Tero Kristo 462519fc26 crypto: omap-sham - split up data to multiple sg elements with huge data
When using huge data amount, allocating free pages fails as the kernel
isn't able to process get_free_page requests larger than MAX_ORDER.
Also, the DMA subsystem has an inherent limitation that data size
larger than some 2MB can't be handled properly. In these cases,
split up the data instead to smaller requests so that the kernel
can allocate the data, and also so that the DMA driver can handle
the separate SG elements.

Eric Biggers c288178954 crypto: shash - allow essiv and hmac to use OPTIONAL_KEY algorithms
The essiv and hmac templates refuse to use any hash algorithm that has a
->setkey() function, which includes not just algorithms that always need
a key, but also algorithms that optionally take a key.

Previously the only optionally-keyed hash algorithms in the crypto API
were non-cryptographic algorithms like crc32, so this didn't really
matter.  But that's changed with BLAKE2 support being added.  BLAKE2
should work with essiv and hmac, just like any other cryptographic hash.

Fix this by allowing the use of both algorithms without a ->setkey()
function and algorithms that have the OPTIONAL_KEY flag set.

accelerator, and this version was left behind when the maximum
RSA modulus size was parameterized in order to support v5 hardware

Fix this by setting the .rsamax property to the appropriate value
for v3 platform hardware.

Herbert Xu bbefa1dd6a crypto: pcrypt - Avoid deadlock by using per-instance padata queues
If the pcrypt template is used multiple times in an algorithm, then a
deadlock occurs because all pcrypt instances share the same
padata_instance, which completes requests in the order submitted.  That
is, the inner pcrypt request waits for the outer pcrypt request while
the outer request is already waiting for the inner.

This patch fixes this by allocating a set of queues for each pcrypt
instance instead of using two global queues.  In order to maintain
the existing user-space interface, the pinst structure remains global
so any sysfs modifications will apply to every pcrypt instance.

Note that when an update occurs we have to allocate memory for
every pcrypt instance.  Should one of the allocations fail we
will abort the update without rolling back changes already made.

The new per-instance data structure is called padata_shell and is
essentially a wrapper around parallel_data.

Reproducer:

	#include <linux/if_alg.h>
	#include <sys/socket.h>
	#include <unistd.h>

	int main()
	{
		struct sockaddr_alg addr = {
			.salg_type = "aead",
			.salg_name = "pcrypt(pcrypt(rfc4106-gcm-aesni))"
		};
		int algfd, reqfd;
		char buf[32] = { 0 };

		algfd = socket(AF_ALG, SOCK_SEQPACKET, 0);
		bind(algfd, (void *)&addr, sizeof(addr));
		setsockopt(algfd, SOL_ALG, ALG_SET_KEY, buf, 20);
		reqfd = accept(algfd, 0, 0);
		write(reqfd, buf, 32);
		read(reqfd, buf, 16);
	}

Herbert Xu 07928d9bfc padata: Remove broken queue flushing
The function padata_flush_queues is fundamentally broken because
it cannot force padata users to complete the request that is
underway.  IOW padata has to passively wait for the completion
of any outstanding work.

As it stands flushing is used in two places.  Its use in padata_stop
is simply unnecessary because nothing depends on the queues to
be flushed afterwards.

The other use in padata_replace is more substantial as we depend
on it to free the old pd structure.  This patch instead uses the
pd->refcnt to dynamically free the pd structure once all requests
are complete.

Linus Torvalds 316933cf74 orangefs: posix open permission checking...
Orangefs has no open, and orangefs checks file permissions
 on each file access. Posix requires that file permissions
 be checked on open and nowhere else. Orangefs-through-the-kernel
 needs to seem posix compliant.
 
 The VFS opens files, even if the filesystem provides no
 method. We can see if a file was successfully opened for
 read and or for write by looking at file->f_mode.
 
 When writes are flowing from the page cache, file is no
 longer available. We can trust the VFS to have checked
 file->f_mode before writing to the page cache.
 
 The mode of a file might change between when it is opened
 and IO commences, or it might be created with an arbitrary mode.
 
 We'll make sure we don't hit EACCES during the IO stage by
 using UID 0.

Linus Torvalds 911d137ab0 This is a relatively quiet cycle for nfsd, mainly various bugfixes.
Possibly most interesting is Trond's fixes for some callback races that
 were due to my incomplete understanding of rpc client shutdown.
 Unfortunately at the last minute I've started noticing a new
 intermittent failure to send callbacks.  As the logic seems basically
 correct, I'm leaving Trond's patches in for now, and hope to find a fix
 in the next week so I don't have to revert those patches.

Steve French 231e2a0ba5 smb3: improve check for when we send the security descriptor context on create
We had cases in the previous patch where we were sending the security
descriptor context on SMB3 open (file create) in cases when we hadn't
mounted with with "modefromsid" mount option.

Add check for that mount flag before calling ad_sd_context in
open init.
