Pull keys fixes from James Morris:
- Handle quotas better, allowing full quota to be reached.
- Fix the creation of shortcuts in the assoc_array internal
representation when the index key needs to be an exact multiple of
the machine word size.
- Fix a dependency loop between the request_key contruction record and
the request_key authentication key. The construction record isn't
really necessary and can be dispensed with.
- Set the timestamp on a new key rather than leaving it as 0. This
would ordinarily be fine - provided the system clock is never set to
a time before 1970

to truncate arguments as well, which broke userspace, and it was
reverted. This attempts the protection again, but allows arguments to
remain truncated. In an effort to improve readability, helper functions

====================
Address recent issues found in netdev page_frag_alloc usage
This patch set addresses a couple of issues that I had pointed out to Jann
Horn in response to a recent patch submission.
The first issue is that I wanted to avoid the need to read/modify/write the
size value in order to generate the value for pagecnt_bias. Instead we can
just use a fixed constant which reduces the need for memory read operations
and the overall number of instructions to update the pagecnt bias values.
The other, and more important issue is, that apparently we were letting tun
access the napi_alloc_cache indirectly through netdev_alloc_frag and as a
result letting it create unaligned accesses via unaligned allocations. In
order to prevent this I have added a call to SKB_DATA_ALIGN for the fragsz
field so that we will keep the offset in the napi_alloc_cache
SMP_CACHE_BYTES aligned.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
This patch addresses the fact that there are drivers, specifically tun,
that will call into the network page fragment allocators with buffer sizes
that are not cache aligned. Doing this could result in data alignment
and DMA performance issues as these fragment pools are also shared with the
skb allocator and any other devices that will use napi_alloc_frags or
netdev_alloc_frags.

This patch replaces the size + 1 value introduced with the recent fix for 1
byte allocs with a constant value.
The idea here is to reduce code overhead as the previous logic would have
to read size into a register, then increment it, and write it back to
whatever field was being used. By using a constant we can avoid those
memory reads and arithmetic operations in favor of just encoding the
maximum value into the operation itself.

The function-local variable "delay" enters the loop interpreted as delay
in bits. However, inside the loop it gets overwritten by the result of
mlxsw_sp_pg_buf_delay_get(), and thus leaves the loop as quantity in
cells. Thus on second and further loop iterations, the headroom for a
given priority is configured with a wrong size.
Fix by introducing a loop-local variable, delay_cells. Rename thres to

Now that LEDs core allows "blocking" flavor of "set brightness" method we
can use it and get rid of private work item. As a bonus, we are no longer
forgetting to cancel it when we unbind the driver.

In v4.20 we changed our pgd/pud_present() to check for _PAGE_PRESENT
rather than just checking that the value is non-zero, e.g.:
static inline int pgd_present(pgd_t pgd)
{
- return !pgd_none(pgd);
+ return (pgd_raw(pgd) & cpu_to_be64(_PAGE_PRESENT));
}
Unfortunately this is broken on big endian, as the result of the
bitwise & is truncated to int, which is always zero because
_PAGE_PRESENT is 0x8000000000000000ul. This means pgd_present() and
pud_present() are always false at compile time, and the compiler
elides the subsequent code.
Remarkably with that bug present we are still able to boot and run
with few noticeable effects. However under some work loads we are able
to trigger a warning in the ext4 code:
WARNING: CPU: 11 PID: 29593 at fs/ext4/inode.c:3927 .ext4_set_page_dirty+0x70/0xb0
CPU: 11 PID: 29593 Comm: debugedit Not tainted 4.20.0-rc1 #1
...
NIP .ext4_set_page_dirty+0x70/0xb0

.__vm_munmap+0x80/0x110
.__se_sys_munmap+0x14/0x30
system_call+0x5c/0x70
The fix is simple, we need to convert the result of the bitwise & to
an int before returning it.
Thanks to Erhard, Jan Kara and Aneesh for help with debugging.
