xen-netback: support frontends without feature-rx-notify again
Commit
bc96f648df1bbc2729abbb84513cf4f64273a1f1 (xen-netback: make
feature-rx-notify mandatory) incorrectly assumed that there were no
frontends in use that did not support this feature. But the frontend
driver in MiniOS does not and since this is used by (qemu) stubdoms,
these stopped working.
Netback sort of works as-is in this mode except:
- If there are no Rx requests and the internal Rx queue fills, only
the drain timeout will wake the thread. The default drain timeout
of 10 s would give unacceptable pauses.
- If an Rx stall was detected and the internal Rx queue is drained,
then the Rx thread would never wake.
Handle these two cases (when feature-rx-notify is disabled) by:
- Reducing the drain timeout to 30 ms.
- Disabling Rx stall detection.

Bluetooth: Fix bug with filter in service discovery optimization
The optimization for filtering out extended inquiry results, advertising
reports or scan response data based on provided UUID list has a logic
bug. In case no match is found in the advertising data, the scan
response is ignored and not checked against the filter. This will lead
to events being filtered wrongly.
Change the code to actually only drop the events when the scan response
data is not present. If it is present, it needs to be checked against
the provided filter.
The patch is a bit more complex than it needs to be. That is because
it also fixes this compiler warning that some gcc versions produce.

xen-netfront: use napi_complete() correctly to prevent Rx stalling
After
d75b1ade567ffab085e8adbbdacf0092d10cd09c (net: less interrupt
masking in NAPI) the napi instance is removed from the per-cpu list
prior to calling the n->poll(), and is only requeued if all of the
budget was used. This inadvertently broke netfront because netfront
does not use NAPI correctly.
If netfront had not used all of its budget it would do a final check
for any Rx responses and avoid calling napi_complete() if there were
more responses. It would still return under budget so it would never
be rescheduled. The final check would also not re-enable the Rx
interrupt.
Additionally, xenvif_poll() would also call napi_complete() /after/
enabling the interrupt. This resulted in a race between the
napi_complete() and the napi_schedule() in the interrupt handler. The
use of local_irq_save/restore() avoided by race iff the handler is
running on the same CPU but not if it was running on a different CPU.
Fix both of these by always calling napi_compete() if the budget was
not all used, and then calling napi_schedule() if the final checks

tun/macvtap: TUNSETIFF fixes
Dan Carpenter reported the following:
static checker warning:
drivers/net/tun.c:1694 tun_set_iff()
warn: 0x17100 is larger than 16 bits
drivers/net/tun.c
1692
1693 tun->flags = (tun->flags & ~TUN_FEATURES) |
1694 (ifr->ifr_flags & TUN_FEATURES);
1695
It's complaining because the "ifr->ifr_flags" variable is a short
(should it be unsigned?). The new define:
#define IFF_VNET_LE 0x10000
doesn't fit in two bytes. Other suspect looking code could be:
return __virtio16_to_cpu(q->flags & IFF_VNET_LE, val);
And that's true: we have run out of IFF flags in tun.
So let's not try to add more: add simple GET/SET ioctls
instead. Easy to test, leads to clear semantics.
Alternatively we'll have to revert the whole thing for 3.19,
but that seems more work as this has dependencies
in other places.
While here, I noticed that macvtap was actually reading
ifreq flags as a 32 bit field.
Fix that up as well.

uses zero-length arrays in the non-debug case, and so it doesn't

The inner mac was thus set differently in nbma case: the GRE header

Now that the offloads expect mac header to point to the gre payload,

Pull take two of the GPIO updates:
"Same stuff as last time, now with a fixup patch for the previous
compile error plus I ran a few extra rounds of compile-testing.
This is the bulk of GPIO changes for the v3.19 series:
- A new API that allows setting more than one GPIO at the time. This
is implemented for the new descriptor-based API only and makes it
possible to e.g. toggle a clock and data line at the same time, if
the hardware can do this with a single register write. Both
consumers and drivers need new calls, and the core will fall back
to driving individual lines where needed. Implemented for the
MPC8xxx driver initially
- Patched the mdio-mux-gpio and the serial mctrl driver that drives
modems to use the new multiple-setting API to set several signals
simultaneously
- Get rid of the global GPIO descriptor array, and instead allocate
descriptors dynamically for each GPIO on a certain GPIO chip. This
moves us closer to getting rid of the limitation of using the
global, static GPIO numberspace
- New driver and device tree bindings for 74xx ICs
- New driver and device tree bindings for the VF610 Vybrid
- Support the RCAR r8a7793 and r8a7794
- Guidelines for GPIO device tree bindings trying to get things a bit

x86/tls: Disallow unusual TLS segments
Users have no business installing custom code segments into the
GDT, and segments that are not present but are otherwise valid
are a historical source of interesting attacks.
For completeness, block attempts to set the L bit. (Prior to
this patch, the L bit would have been silently dropped.)
This is an ABI break. I've checked glibc, musl, and Wine, and
none of them look like they'll have any trouble.
Note to stable maintainers: this is a hardening patch that fixes
no known bugs. Given the possibility of ABI issues, this
probably shouldn't be backported quickly.

aio: Make it possible to remap aio ring
There are actually two issues this patch addresses. Let me start with
the one I tried to solve in the beginning.
So, in the checkpoint-restore project (criu) we try to dump tasks'
state and restore one back exactly as it was. One of the tasks' state
bits is rings set up with io_setup() call. There's (almost) no problems
in dumping them, there's a problem restoring them -- if I dump a task
with aio ring originally mapped at address A, I want to restore one
back at exactly the same address A. Unfortunately, the io_setup() does
not allow for that -- it mmaps the ring at whatever place mm finds
appropriate (it calls do_mmap_pgoff() with zero address and without
the MAP_FIXED flag).
To make restore possible I'm going to mremap() the freshly created ring
into the address A (under which it was seen before dump). The problem is
that the ring's virtual address is passed back to the user-space as the
context ID and this ID is then used as search key by all the other io_foo()
calls. Reworking this ID to be just some integer doesn't seem to work, as
this value is already used by libaio as a pointer using which this library
accesses memory for aio meta-data.
So, to make restore work we need to make sure that
a) ring is mapped at desired virtual address
b) kioctx->user_id matches this value
Having said that, the patch makes mremap() on aio region update the
kioctx's user_id and mmap_base values.
Here appears the 2nd issue I mentioned in the beginning of this mail.
If (regardless of the C/R dances I do) someone creates an io context
with io_setup(), then mremap()-s the ring and then destroys the context,
the kill_ioctx() routine will call munmap() on wrong (old) address.
This will result in a) aio ring remaining in memory and b) some other
vma get unexpectedly unmapped.
What do you think?

percpu: remove __get_cpu_var and __raw_get_cpu_var macros
No user is left in the kernel source tree. Therefore we can drop the
definitions.
This is the final merge of the transition away from __get_cpu_var. After
this patch the kernel will not build if anyone uses __get_cpu_var.

fsnotify: remove destroy_list from fsnotify_mark
destroy_list is used to track marks which still need waiting for srcu
period end before they can be freed. However by the time mark is added to
destroy_list it isn't in group's list of marks anymore and thus we can
reuse fsnotify_mark->g_list for queueing into destroy_list. This saves
two pointers for each fsnotify_mark.

fallocate: create FAN_MODIFY and IN_MODIFY events
The fanotify and the inotify API can be used to monitor changes of the
file system. System call fallocate() modifies files. Hence it should
trigger the corresponding fanotify (FAN_MODIFY) and inotify (IN_MODIFY)
events. The most interesting case is FALLOC_FL_COLLAPSE_RANGE because
this value allows to create arbitrary file content from random data.
This patch adds the missing call to fsnotify_modify().
The FAN_MODIFY and IN_MODIFY event will be created when fallocate()
succeeds. It will even be created if the file length remains unchanged,
e.g. when calling fanotify with flag FALLOC_FL_KEEP_SIZE.
This logic was primarily chosen to keep the coding simple.
It resembles the logic of the write() system call.
When we call write() we always create a FAN_MODIFY event, even in the case
of overwriting with identical data.
Events FAN_MODIFY and IN_MODIFY do not provide any guarantee that data was
actually changed.
Furthermore even if if the filesize remains unchanged, fallocate() may
influence whether a subsequent write() will succeed and hence the
fallocate() call may be considered a modification.
The fallocate(2) man page teaches: After a successful call, subsequent
writes into the range specified by offset and len are guaranteed not to
fail because of lack of disk space.
So calling fallocate(fd, FALLOC_FL_KEEP_SIZE, offset, len) may result in
different outcomes of a subsequent write depending on the values of offset
and len.

mm/cma: make kmemleak ignore CMA regions
kmemleak will add allocations as objects to a pool. The memory allocated
for each object in this pool is periodically searched for pointers to
other allocated objects. This only works for memory that is mapped into
the kernel's virtual address space, which happens not to be the case for
most CMA regions.
Furthermore, CMA regions are typically used to store data transferred to
or from a device and therefore don't contain pointers to other objects.
Without this, the kernel crashes on the first execution of the
scan_gray_list() because it tries to access highmem. Perhaps a more
appropriate fix would be to reject any object that can't map to a kernel
virtual address?

slub: fix cpuset check in get_any_partial
If we fail to allocate from the current node's stock, we look for free
objects on other nodes before calling the page allocator (see
get_any_partial). While checking other nodes we respect cpuset
constraints by calling cpuset_zone_allowed. We enforce hardwall check.
As a result, we will fallback to the page allocator even if there are some
pages cached on other nodes, but the current cpuset doesn't have them set.
However, the page allocator uses softwall check for kernel allocations,
so it may allocate from one of the other nodes in this case.
Therefore we should use softwall cpuset check in get_any_partial to
conform with the cpuset check in the page allocator.
