David Fries f28c4e1f31 w1: ds2490 reduce magic numbers
Use a #define for the usb vendor request type, clear the status
byte and use that instead of a magic offset in checking if idle.

David Fries 5dbf5671c7 w1: reply only to the requester portid
Unicast one wire replies back to the sender portid to avoid multiple
programs getting each other's messages, especially as the response
can't be uniquely identified with the sequence coming from the
requesting program when both programs generate the same id.  Continue
to broadcast events such as add/remove master/slave devices.

David Fries 9fcbbac5de w1: process w1 netlink commands in w1_process thread
Netlink is a socket interface and is expected to be asynchronous.
Clients can now make w1 requests without blocking by making use of the
w1_master thread to process netlink commands which was previously only
used for doing an automatic bus search.

David Fries 70b34d2ed8 w1: new netlink commands, add/remove/list slaves
Introduce new commands to add, remove, and list slave devices through
the netlink interface.  This can be useful to skip the search on a
static network.  They could previously only be added or removed
through automatic search or sysfs, and this allows a program to only
use netlink.

Only allocate memory when needed, so move kzalloc into w1_get_slaves
where it was used.

David Fries a16130569a w1: increase w1_max_slave_count, allow write access
w1_max_slave_count is only used to abort the search early
or take a fast search (when 1), so there isn't any reason to not allow
it to be updated through sysfs.  Memory is not allocated based on
the current value and 10 is a rather low base number, increasing to
64, and printing a message the first time the count is reached and
there were more devices to discover to let the user know why not
all the devices were found.

David Fries 4210569876 w1: fixup search to support abort from netlink
Before 63706172f3 "rework kthread_stop()" kthread_should_stop()
always returned false when called from a non-kthread task, after it
would oops as a non-kthread didn't have that structure and netlink was
calling search from a thread which wasn't a kthread.  9d1817cab2
"w1: fix oops when w1_search is called from netlink connector",
modified the code to avoid calling kthread_stop from a netlink thread.

Introduce a w1_master flag and bit W1_ABORT_SEARCH to identify abort
to cleanly support both kthread and netlink search abort.  A search
can take seconds to run, so it is important to abort early if the
hardware is removed in the middle of a search.

David Fries 6b355b33a6 w1: fix w1_send_slave dropping a slave id
Previous logic,
if (avail > 8) {
	store slave;
	return;
}
send data; clear;

The logic error is, if there isn't space send the buffer and clear,
but the slave wasn't added to the now empty buffer loosing that slave
id.  It also should have been "if (avail >= 8)" because when it is 8,
there is space.

Instead, if there isn't space send and clear the buffer, then there is
always space for the slave id.

Sudeep Dutt 3b1cc9b962 misc: mic: fix possible signed underflow (undefined behavior) in userspace API
iovcnt is declared as a signed integer in both the userspace API and
as a local variable in mic_virtio.c. The while() loop in mic_virtio.c
iterates until the local variable iovcnt reaches the value 0. If
userspace passes e.g. INT_MIN as iovcnt field, this loop then appears
to depend on an undefined behavior (signed underflow) to complete.
The fix is to use unsigned integers in both the userspace API and
the local variable.

Sarah Sharp 247bf55727 xhci 1.0: Limit arbitrarily-aligned scatter gather.
xHCI 1.0 hosts have a set of requirements on how to align transfer
buffers on the endpoint rings called "TD fragment" rules.  When the
ax88179_178a driver added support for scatter gather in 3.12, with
commit 804fad45411b48233b48003e33a78f290d227c8 "USBNET: ax88179_178a:
enable tso if usb host supports sg dma", it broke the device under xHCI
1.0 hosts.  Under certain network loads, the device would see an
unexpected short packet from the host, which would cause the device to
stop sending ethernet packets, even through USB packets would still be
sent.

Commit 35773dac5f "usb: xhci: Link TRB must not occur within a USB
payload burst" attempted to fix this.  It was a quick hack to partially
implement the TD fragment rules.  However, it caused regressions in the
usb-storage layer and userspace USB drivers using libusb.  The patches
to attempt to fix this are too far reaching into the USB core, and we
really need to implement the TD fragment rules correctly in the xHCI
driver, instead of continuing to wallpaper over the issues.

Disable arbitrarily-aligned scatter-gather in the xHCI driver for 1.0
hosts.  Only the ax88179_178a driver checks the no_sg_constraint flag,
so don't set it for 1.0 hosts.  This should not impact usb-storage or
usbfs behavior, since they pass down max packet sized aligned sg-list
entries (512 for USB 2.0 and 1024 for USB 3.0).

Shlomo Pongratz d7790b928d block/null_blk: Fix completion processing from LIFO to FIFO
The completion queue is implemented using lockless list.

The llist_add is adds the events to the list head which is a push operation.
The processing of the completion elements is done by disconnecting all the
pushed elements and iterating over the disconnected list. The problem is
that the processing is done in reverse order w.r.t order of the insertion
i.e. LIFO processing. By reversing the disconnected list which is done in
linear time the desired FIFO processing is achieved.

Kent Overstreet 5cb8850c9c block: Explicitly handle discard/write same segments
Immutable biovecs changed the way biovecs are interpreted - drivers no
longer use bi_vcnt, they have to go by bi_iter.bi_size (to allow for
using part of an existing segment without modifying it).

This breaks with discards and write_same bios, since for those bi_size
has nothing to do with segments in the biovec. So for now, we need a
fairly gross hack - we fortunately know that there will never be more
than one segment for the entire request, so we can special case
discard/write_same.

Jan Moskyto Matejka 03b56329f9 Modpost: fixed USB alias generation for ranges including 0x9 and 0xA
Commit afe2dab4f6 ("USB: add hex/bcd detection to usb modalias generation")
changed the routine that generates alias ranges. Before that change, only
digits 0-9 were supported; the commit tried to fix the case when the range
includes higher values than 0x9.

Unfortunately, the commit didn't fix the case when the range includes both
0x9 and 0xA, meaning that the final range must look like [x-9A-y] where
x <= 0x9 and y >= 0xA -- instead the [x-9A-x] range was produced.

Modprobe doesn't complain as it sees no difference between no-match and
bad-pattern results of fnmatch().

Fixing this simple bug to fix the aliases.
Also changing the hardcoded beginning of the range to uppercase as all the
other letters are also uppercase in the device version numbers.

Fortunately, this affects only the dvb-usb-dib0700 module, AFAIK.
