there is a tiny bug in Documentation/crypto/api-intro.txt.
The file has the following example code:
struct scatterlist sg[2];
[...]
if (crypto_hash_digest(&desc, &sg, 2, result))
which does not match the declaration of crypto_hash_digest() in
include/linux/crypto.h.
(static inline int crypto_hash_digest(struct hash_desc *desc,
struct scatterlist *sg, unsigned int nbytes, u8 *out)
The code in the example passes the address of a pointer (an array actually) as
the second argument, while the function expects the pointer itself.
I have attached a patch to fix this.

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
5c64097aa0, first in 2.6.19-rc1.

In sn_io_slot_fixup(), the parent is re-set from the bus to
io(port|mem)_resource because the address is changed in a way that it's not
child of the bus any more.
However, only the root is set but not the parent/child/sibling relationship in
the resource tree which causes 'cat /proc/iomem' to stop after this memory
area. Depding on the poition in the tree the iomem may be nearly completely
empty.

When booting an SN system without specifing a console
(i.e., no "console=" on boot line), the system will hang during
boot at the point where /sbin/init is run.
The problem is that vga_console_iobase is not converted to a
virtual address before storing in io_space[0].mmio_base.
The conversion was happening in sn_scan_pcdp(), but not in
setup_vga_console().

If a system consists of mixed processor types, kmalloc()
can be called before the per-cpu data page is initialized.
If the slab contains sufficient memory, then kmalloc() works
ok. However, if the slabs are empty, slab calls the memory

cpu dies.

We have seen bad_pte_print when testing crashdump on an SN machine in
recent 2.6.20 kernel. There are tons of bad pte print (pfn < max_low_pfn)
reports when the crash kernel boots up, all those reported bad pages
are inside initmem range; That is because if the crash kernel code and
data happens to be at the beginning of the 1st node. build_node_maps in
discontig.c will bypass reserved regions with filter_rsvd_memory. Since
min_low_pfn is calculated in build_node_map, so in this case, min_low_pfn
will be greater than kernel code and data.
Because pages inside initmem are freed and reused later, we saw
pfn_valid check fail on those pages.
I think this theoretically happen on a normal kernel. When I check
min_low_pfn and max_low_pfn calculation in contig.c and discontig.c.
I found more issues than this.
1. min_low_pfn and max_low_pfn calculation is inconsistent between
contig.c and discontig.c,
min_low_pfn is calculated as the first page number of boot memmap in
contig.c (Why? Though this may work at the most of the time, I don't
think it is the right logic). It is calculated as the lowest physical
memory page number bypass reserved regions in discontig.c.
max_low_pfn is calculated include reserved regions in contig.c. It is
calculated exclude reserved regions in discontig.c.
2. If kernel code and data region is happen to be at the begin or the
end of physical memory, when min_low_pfn and max_low_pfn calculation is
bypassed kernel code and data, pages in initmem will report bad.
3. initrd is also in reserved regions, if it is at the begin or at the
end of physical memory, kernel will refuse to reuse the memory. Because
the virt_addr_valid check in free_initrd_mem.
So it is better to fix and clean up those issues.
Calculate min_low_pfn and max_low_pfn in a consistent way.

The manual says that it is required and we actually have crash reports
where loads see stale data due to not having membars here.
In one case the networking does:
memset(skb, 0, offsetof(struct sk_buff, truesize));
and then some code later checks skb->nohdr for zero, but it's still
the value that was there before the memset().

Add an ID to recognise the Novatel EV620 wireless adapter.

It looks like a mini PCI-Express adapter. The mPCIE connector includes USB
pins... the card shows up to the system as a USB device, and powers itself
from the PCI bus.
The card I have isn't activated yet, so I can't get a PPP session up yet, but
I have tested basic serial communication successfully in both 2.6.18 and
2.6.20 kernels, once the product ID was added. (the driver changed quite a

these devices have a shared interrupt endpoint. For serialcore to pass
an interrupt endpoint to a subdriver, the subdriver must define and
_export_ a fitting callback. The mos7720 driver failed to do so. This led
invariably to an oops upon open. This patch fixes it. The driver is useless
without it. Please try to get this into 2.6.21 and the stable kernels that

These leaks were reported by: Catalin Marinas <catalin.marians@gmail.com>
and I have been able to very by inspection they are possible.
When converting tty_io.c to store pids as struct pid pointers instead
of pid_t values it appears I overlooked two places where we stop using
the pid value. The very obvious one is in do_tty_hangup, and the one
the less obvious one in __proc_set_tty.
When looking into the code __proc_set_tty only has pids that need to
be put because of failures of other parts of the code to properly
perform hangup processing. Fixing the leak here in __proc_set_tty
is easy and obviously correct so I am doing that first.
Fixing the places that should be performing hangup processing is much
less obviously correct. So those I'm aiming those patches at -mm.
for now, so the can age a while before they are merged.
