The hid descriptor identifies the length and type of subordinate
descriptors for a device. If the received hid descriptor is smaller than
the size of the struct hid_descriptor, it is possible to cause
out-of-bounds.

In addition, if bNumDescriptors of the hid descriptor have an incorrect
value, this can also cause out-of-bounds while approaching hdesc->desc[n].

So check the size of hid descriptor and bNumDescriptors.

When an incoming module is considered for livepatching by
klp_module_coming(), it iterates over multiple patches and multiple
kernel objects in this order:

	list_for_each_entry(patch, &klp_patches, list) {
		klp_for_each_object(patch, obj) {

which means that if one of the kernel objects fails to patch,
klp_module_coming()'s error path needs to unpatch and cleanup any kernel
objects that were already patched by a previous patch.

There is a potential race window opened at creating and deleting a
port via ioctl, as spotted by fuzzing.  snd_seq_create_port() creates
a port object and returns its pointer, but it doesn't take the
refcount, thus it can be deleted immediately by another thread.
Meanwhile, snd_seq_ioctl_create_port() still calls the function
snd_seq_system_client_ev_port_start() with the created port object
that is being deleted, and this triggers use-after-free like:

We may fix this in a few different ways, and in this patch, it's fixed
simply by taking the refcount properly at snd_seq_create_port() and
letting the caller unref the object after use.  Also, there is another
potential use-after-free by sprintf() call in snd_seq_create_port(),
and this is moved inside the lock.

This fix covers CVE-2017-15265.

sdio->bio can currently be NULL when calling dio_bio_submit.  This then
leads to a NULL pointer access in dio_bio_submit, so check for a NULL
bio in submit_page_section before trying to submit it instead.

Actually such a URB is killed properly at disconnection when the
device gets probed successfully, and what we need is to apply it for
the error-path, too.

In this patch, we apply snd_usb_mixer_disconnect() at releasing.
Also introduce a new flag, disconnected, to struct usb_mixer_interface
for not performing the disconnection procedure twice.

The u-blox TOBY-L2 is a LTE Cat 4 module with HSPA+ and 2G fallback.
This module allows switching to different USB profiles with the
'AT+UUSBCONF' command, and provides a ECM network interface when the
'AT+UUSBCONF=2' profile is selected.

The u-blox SARA-U2 is a HSPA module with 2G fallback. The default USB
configuration includes a ECM network interface.

Both these modules are controlled via AT commands through one of the
TTYs exposed. Connecting these modules may be done just by activating
the desired PDP context with 'AT+CGACT=1,<cid>' and then running DHCP
on the ECM interface.

Netfilter/IPVS fixes for net

The following patchset contains Netfilter/IPVS fixes for your net tree,
they are:

1) Fix packet drops due to incorrect ECN handling in IPVS, from Vadim
   Fedorenko.

2) Fix splat with mark restoration in xt_socket with non-full-sock,
   patch from Subash Abhinov Kasiviswanathan.

3) ipset bogusly bails out when adding IPv4 range containing more than
   2^31 addresses, from Jozsef Kadlecsik.

4) Incorrect pernet unregistration order in ipset, from Florian Westphal.

5) Races between dump and swap in ipset results in BUG_ON splats, from
   Ross Lagerwall.

6) Fix chain renames in nf_tables, from JingPiao Chen.

7) Fix race in pernet codepath with ebtables table registration, from
   Artem Savkov.

8) Memory leak in error path in set name allocation in nf_tables, patch
   from Arvind Yadav.

9) Don't dump chain counters if they are not available, this fixes a
   crash when listing the ruleset.

10) Fix out of bound memory read in strlcpy() in x_tables compat code,
    from Eric Dumazet.

11) Make sure we only process TCP packets in SYNPROXY hooks, patch from
    Lin Zhang.

12) Cannot load rules incrementally anymore after xt_bpf with pinned
    objects, added in revision 1. From Shmulik Ladkani.

Intel Wired LAN Driver Updates 2017-10-09

This series contains updates to ixgbe and arch/Kconfig.

Mark fixes a case where PHY register access is not supported and we were
returning a PHY address, when we should have been returning -EOPNOTSUPP.

Sabrina Dubroca fixes the use of a logical "and" when it should have been
the bitwise "and" operator.

Ding Tianhong reverts the commit that added the Kconfig bool option
ARCH_WANT_RELAX_ORDER, since there is now a new flag
PCI_DEV_FLAGS_NO_RELAXED_ORDERING that has been added to indicate that
Relaxed Ordering Attributes should not be used for Transaction Layer
Packets.  Then follows up with making the needed changes to ixgbe to
use the new PCI_DEV_FLAGS_NO_RELAXED_ORDERING flag.

John Fastabend fixes an issue in the ring accounting when the transmit
ring parameters are changed via ethtool when an XDP program is attached.
