Linus Torvalds 58ccab9134 Leonidas Spyropoulos found that modules like nouveau were being unselected
by make localmodconfig even though their configs were set and the module
 was loaded and visible by lsmod. The reason for this was because
 streamline-config.pl only looks at Makefiles, and not Kbuild files. As
 these modules use Kbuild for their names, they too need to be checked
 by localmodconfig. This was fixed by Richard Weinberger.

In kbuild it is allowed to define objects in files named "Makefile"
and "Kbuild".
Currently localmodconfig reads objects only from "Makefile"s and misses
modules like nouveau.

====================
pull request: bluetooth 2015-08-11

Here's an important regression fix for the 4.2-rc series that ensures
user space isn't given invalid LTK values. The bug essentially prevents
the encryption of subsequent LE connections, i.e. makes it impossible to
pair devices over LE.

Let me know if there are any issues pulling. Thanks.

This patch moves module_init of 6lowpan module into core functionality
of 6lowpan module. To load the ipv6 module at probing of the 6lowpan
module should be core functionality. Loading next header compression
modules is iphc specific. Nevertheless we only support IPHC for the
generic 6LoWPAN branch right now so we can put it into the core
functionality. If possible new compression formats are introduced nhc
should load only when iphc is build.

Vivien Didelot says:

====================
net: dsa: mv88e6xxx: support switchdev FDB objects

This patchset refactors the FDB management in the mv88e6xxx code and adds the
glue in DSA to use the switchdev FDB objects.

Below is an usage example (ports 0-2 belongs to br0, ports 3-4 belongs to br1):

    # bridge fdb add 3c:97:0e:11:30:6e dev swp2
    # bridge fdb add 3c:97:0e:11:40:78 dev swp3
    # bridge fdb add 3c:97:0e:11:50:86 dev swp4
    # bridge fdb del 3c:97:0e:11:40:78 dev swp3
    # bridge fdb
    01:00:5e:00:00:01 dev eth0 self permanent
    01:00:5e:00:00:01 dev eth1 self permanent
    00:50:d2:10:78:15 dev swp0 master br0 permanent
    3c:97:0e:11:30:6e dev swp2 self static
    00:50:d2:10:78:15 dev swp3 master br1 permanent
    3c:97:0e:11:50:86 dev swp4 self static
    # cat /sys/kernel/debug/dsa0/atu
    # DB   T/P  Vec State Addr
    # 001  Port 004   e   3c:97:0e:11:30:6e
    # 004  Port 010   e   3c:97:0e:11:50:86

For the 88E6xxx switches, FIDs 1 to num_ports will be reserved for non-bridged
ports and bridge groups, and the remaining will be later used by VLANs.

This change is necessary to welcome the support for hardware VLANs (which will
follow soon).

Changes in v3:

 - reorder commits to improve bisectability and minimize diffs

 - add an ndm_state member in switchdev_fdb_obj instead of an is_static boolean

 - drop the need to convert unsigned char *addr to u8 addr[ETH_ALEN]
   (it is casted to char pointer anyway)

Changes in v2:

 - remove ndo_bridge_{get,set,del}link from switchdev/DSA glue code

 - use ether_addr_copy instead of memcpy for MAC addresses

 - constify MAC address in port_fdb_{add,del}

 - split the mv88e6xxx code refactoring into several patches

Vivien Didelot 194fea7bd8 net: dsa: mv88e6xxx: extend fid mask
The driver currently manages one FID per port (or bridge group), with a
mask of DSA_MAX_PORTS bits, where 0 means that the FID is in use.

The Marvell 88E6xxx switches support up to 4094 FIDs (from 1 to 0xfff;
FID 0 means that multiple address databases are not being used).

This patch changes the fid_mask for an fid_bitmap of 4096 bits.

>From now on, FIDs 1 to num_ports are reserved for non-bridged ports and
bridge groups (a bridge group gets the FID of its first member). The
remaining bits will be reserved for VLAN entries.

Ruben Wisniewski 571a963768 batman-adv: Avoid u32 overflow during gateway select
The gateway selection based on fast connections is using a single value
calculated from the average tq (0-255) and the download bandwidth (in
100Kibit). The formula for the first step (tq ** 2 * 10000 * bandwidth)
tends to overflow a u32 with low bandwidth settings like 50 [100KiBit]
and a tq value of over 92.

Changing this to a 64 bit unsigned integer allows to support a
bandwidth_down with up to ~2.8e10 [100KiBit] and a perfect tq of 255. This
is ~6.6 times higher than the maximum possible value of the gateway
announcement TVLV.

This problem only affects the non-default gw_sel_class 1.

The gw_factor is divided by BATADV_TQ_LOCAL_WINDOW_SIZE ** 2 * 64. But the
rest of the calculation has nothing to do with the tq window size and
therefore the calculation is just (tmp_gw_factor / (64 ** 3)).

Replace it with a simple shift to avoid a costly 64-bit divide when the
max_gw_factor is changed from u32 to u64. This type change is necessary
to avoid an overflow bug.

Thomas Egerer eae8dee992 xfrm6: Fix IPv6 ECN decapsulation
Using ipv6_get_dsfield on the outer IP header implies that inner and
outer header are of the the same address family. For interfamily
tunnels, particularly 646, the code reading the DSCP field obtains the
wrong values (IHL and the upper four bits of the DSCP field).
This can cause the code to detect a congestion encoutered state in the
outer header and enable the corresponding bits in the inner header, too.

Since the DSCP field is stored in the xfrm mode common buffer
independently from the IP version of the outer header, it's safe (and
correct) to take this value from there.

free_xenballooned_pages() in xenbus_unmap_ring_vfree_hvm(), leaking a
page for every shared ring.

Only with backends running in HVM domains were affected.

Eric Dumazet 3257d8b12f inet: fix possible request socket leak
In commit b357a364c5 ("inet: fix possible panic in
reqsk_queue_unlink()"), I missed fact that tcp_check_req()
can return the listener socket in one case, and that we must
release the request socket refcount or we leak it.

Tested:

 Following packetdrill test template shows the issue

0     socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
+0    setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
+0    bind(3, ..., ...) = 0
+0    listen(3, 1) = 0

+0    < S 0:0(0) win 2920 <mss 1460,sackOK,nop,nop>
+0    > S. 0:0(0) ack 1 <mss 1460,nop,nop,sackOK>
+.002 < . 1:1(0) ack 21 win 2920

Eric Dumazet 2235f2ac75 inet: fix races with reqsk timers
reqsk_queue_destroy() and reqsk_queue_unlink() should use
del_timer_sync() instead of del_timer() before calling reqsk_put(),
otherwise we could free a req still used by another cpu.

But before doing so, reqsk_queue_destroy() must release syn_wait_lock
spinlock or risk a dead lock, as reqsk_timer_handler() might
need to take this same spinlock from reqsk_queue_unlink() (called from
inet_csk_reqsk_queue_drop())

====================
Netfilter fixes for net

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

1) Silence a warning on falling back to vmalloc(). Since 88eab472ec, we can
   easily hit this warning message, that gets users confused. So let's get rid
   of it.

2) Recently when porting the template object allocation on top of kmalloc to
   fix the netns dependencies between x_tables and conntrack, the error
   checks where left unchanged. Remove IS_ERR() and check for NULL instead.
   Patch from Dan Carpenter.

3) Don't ignore gfp_flags in the new nf_ct_tmpl_alloc() function, from
   Joe Stringer.

4) Fix a crash due to NULL pointer dereference in ip6t_SYNPROXY, patch from
   Phil Sutter.

5) The sequence number of the Syn+ack that is sent from SYNPROXY to clients is
   not adjusted through our NAT infrastructure, as a result the client may
   ignore this TCP packet and TCP flow hangs until the client probes us.  Also
   from Phil Sutter.

Jason Gerecke 0be017120b HID: wacom: Report correct device resolution when using the wireless adapater
The 'wacom_wireless_work' function does not recalculate the tablet's
resolution, causing the value contained in the 'features' struct to
always be reported to userspace. This value is valid only for the pen
interface, meaning that the value will be incorrect for the touchpad (if
present). This in particular causes problems for libinput which relies
on the reported resolution being correct.

This patch adds the necessary calls to recalculate the resolution for
each interface. This requires a little bit of code shuffling since both
the 'wacom_set_default_phy' and 'wacom_calculate_res' are declared below
their new first point of use in 'wacom_wireless_work'.

Yuval Mintz 0ea853dfa9 bnx2x: Free NVRAM lock at end of each page
Writing each 4Kb page into flash might take up-to ~100 miliseconds,
during which time management firmware cannot acces the nvram for its
own uses.

Firmware upgrade utility use the ethtool API to burn new flash images
for the device via the ethtool API, doing so by writing several page-worth
of data on each command. Such action might create problems for the
management firmware, as the nvram might not be accessible for a long time.

This patch changes the write implementation, releasing the nvram lock on
the completion of each page, allowing the management firmware time to
claim it and perform its own required actions.
