Netfilter updates for net-next
The following batch contains netfilter updates for net-next. Basically,
enhancements for xt_recent, skip zeroing of timer in conntrack, fix
linking problem with recent redirect support for nf_tables, ipset
updates and a couple of cleanups. More specifically, they are:
1) Rise maximum number per IP address to be remembered in xt_recent
while retaining backward compatibility, from Florian Westphal.
2) Skip zeroing timer area in nf_conn objects, also from Florian.
3) Inspect IPv4 and IPv6 traffic from the bridge to allow filtering using
using meta l4proto and transport layer header, from Alvaro Neira.
4) Fix linking problems in the new redirect support when CONFIG_IPV6=n
and IP6_NF_IPTABLES=n.
And ipset updates from Jozsef Kadlecsik:
5) Support updating element extensions when the set is full (fixes
netfilter bugzilla id 880).
6) Fix set match with 32-bits userspace / 64-bits kernel.
7) Indicate explicitly when /0 networks are supported in ipset.
8) Simplify cidr handling for hash:*net* types.
9) Allocate the proper size of memory when /0 networks are supported.
10) Explicitly add padding elements to hash:net,net and hash:net,port,
because the elements must be u32 sized for the used hash function.
Jozsef is also cooking ipset RCU conversion which should land soon if
they reach the merge window in time.

The new Extended Scanner Filter Policies feature has to be enabled by

When the controller sends a LE Direct Advertising Report event, the host
must confirm that the resolvable random address provided matches with
its own identity resolving key. If it does, then that advertising report
needs to be processed. If it does not match, the report needs to be
ignored.
This patch adds full support for handling these new reports and using
them for device discovery and connection handling. This means when a
Bluetooth controller supports the Extended Scanner Filter Policies, it
is possible to use directed advertising with LE privacy.

We've got a couple of generic scenarios where all pending mgmt commands
are processed and responses are sent to them. These scenarios are
powering off the adapter and removing the adapter. So far the code has
been generating cmd_status responses with NOT_POWERED and INVALID_INDEX
resposes respectively, but this violates the mgmt specification for
commands that should always generate a cmd_complete.
This patch adds support for specifying a callback for the pending_cmd
context that each command handler can use for command-specific
cmd_complete event generation. The actual per-command event generators
will come in subsequent patches.

Sending the required cmd_complete for the management commands should be
done in one place and not in multiple places. Especially for Start and
Stop Discovery commands this is split into to sending it in case of
failure from the complete handler, but in case of success from the
event state update function triggering mgmt_discovering. This is way
too convoluted and since hci_request serializes the HCI command
processing, send the cmd_complete response from the complete handler
for all cases.
