[CRYPTO] api: Flush the current page right than the next

2007-03-31T02:58:20+00:00

On platforms where flush_dcache_page is needed we're currently flushing
the next page right than the one we've just processed.  This patch fixes
the off-by-one error.

[CRYPTO] api: Use the right value when advancing scatterwalk_copychunks

2007-03-31T02:16:20+00:00

In the scatterwalk_copychunks loop, We should be advancing by
len_this_page and not nbytes.  The latter is the total length.

[CRYPTO] api: scatterwalk_copychunks() fails to advance through scatterlist

2007-03-20T21:50:12+00:00

In the loop in scatterwalk_copychunks(), if walk->offset is zero,
then scatterwalk_pagedone rounds that up to the nearest page boundary:

		walk->offset += PAGE_SIZE - 1;
		walk->offset &= PAGE_MASK;

which is a no-op in this case, so we don't advance to the next element
of the scatterlist array:

		if (walk->offset >= walk->sg->offset + walk->sg->length)
			scatterwalk_start(walk, sg_next(walk->sg));

and we end up copying the same data twice.

It appears that other callers of scatterwalk_{page}done first advance
walk->offset, so I believe that's the correct thing to do here.

This caused a bug in NFS when run with krb5p security, which would
cause some writes to fail with permissions errors--for example, writes
of less than 8 bytes (the des blocksize) at the start of a file.

A git-bisect shows the bug was originally introduced by
5c64097aa0f6dc4f27718ef47ca9a12538d62860, first in 2.6.19-rc1.

[PATCH] mark struct file_operations const 3

2007-02-12T17:48:45+00:00

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.
