4bac6b1807 netfilter: restore POST_ROUTING hook in NF_HOOK_COND
Commit 2249065 ("netfilter: get rid of the grossness in netfilter.h")
inverted the logic for conditional hook invocation, breaking the
POST_ROUTING hook invoked by ip_output().

Correct the logic and remove an unnecessary initialization.

37ee3d5b3e netfilter: nf_defrag_ipv4: fix compilation error with NF_CONNTRACK=n
As reported by Randy Dunlap <randy.dunlap@oracle.com>, compilation
of nf_defrag_ipv4 fails with:

include/net/netfilter/nf_conntrack.h:178: error: 'const struct sk_buff' has no member named 'nfct'

net/nf_conntrack.h must not be included with NF_CONNTRACK=n, add a
few #ifdefs. Long term the header file should be fixed to be usable
even with NF_CONNTRACK=n.

60b8675592 usbnet: Convert dev(dbg|err|warn|info) macros to netdev_<level>
These macros are too similar to the dev_<level> equivalents
but take a usbnet * argument.  Convert them to the recently
introduced netdev_<level> macros and remove the old macros.

The old macros had "\n" appended to the format string.
Add the "\n" to the converted uses.

Some existing uses of the dev<foo> macros in cdc_eem.c
probably mistakenly had trailing "\n".  No "\n" added there.

The macro and type tricks around snmp stats make things a bit

as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly.  All
snmp_mib_*() users which used to cast the argument to (void **) are

0ca3a017a7 CAPI: Rework locking of controller data structures
This patch applies the mutex so far only protecting the controller list
to (almost) all accesses of controller data structures. It also reworks
waiting on state changes in old_capi_manufacturer so that it no longer
poll and holds a module reference to the controller owner while waiting
(the latter was partly done already). Modification and checking of the
blocked state remains racy by design, the caller is responsible for
dealing with this.

ef69bb2ec6 CAPI: Rework controller state notifier
Another step towards proper locking: Rework the callback provided to
capidrv for controller state changes. This is so far attached to an
application, which would require us to hold the corresponding lock
across notification calls.

But there is no direct relation between a controller up/down event and
an application, so let's decouple them and provide a notifier call chain
for those events instead. This notifier chain is first of all used
internally. Here we request the highest priority to unsure that
housekeeping work is done before any other notifications. The chain is
exported via [un]register_capictr_notifier to our only user, capidrv, to
replace the racy and unfixable capi20_set_callback.

54716e3beb net neigh: Decouple per interface neighbour table controls from binary sysctls
Stop computing the number of neighbour table settings we have by
counting the number of binary sysctls.  This behaviour was silly
and meant that we could not add another neighbour table setting
without also adding another binary sysctl.

Don't pass the binary sysctl path for neighour table entries
into neigh_sysctl_register.  These parameters are no longer
used and so are just dead code.

3e5e524ffb netfilter: CONFIG_COMPAT: allow delta to exceed 32767
with 32 bit userland and 64 bit kernels, it is unlikely but possible
that insertion of new rules fails even tough there are only about 2000
iptables rules.

This happens because the compat delta is using a short int.
Easily reproducible via "iptables -m limit" ; after about 2050
rules inserting new ones fails with -ELOOP.

Note that compat_delta included 2 bytes of padding on x86_64, so
structure size remains the same.

a87897edba drm/vmwgfx: Drop scanout flag compat and add execbuf ioctl parameter members. Bumps major.
Even if this bumps the version to 1 it does not mean the driver is
out of staging. From what we know this is the last backwards
incompatible change to the driver.

f77cef3db3 drm/vmwgfx: Update the user-space interface.
When time-based throttling is implemented, we need to bump minor.
When the old way of detecting scanout is removed, we need to bump major.
In the meantime, this change should not break existing user-space.
