vmxnet3: Register shutdown handler for device (fwd) · e9ba47bf

Implement a handler for pci shutdown so that the driver has an

"screaming interrupt" is avoided.

netfilter: nf_qeueue: Drop queue entries on nf_unregister_hook · 8405a8ff

由 Eric W. Biederman 提交于 6月 19, 2015

Add code to nf_unregister_hook to flush the nf_queue when a hook is
unregistered.  This guarantees that the pointer that the nf_queue code
retains into the nf_hook list will remain valid while a packet is
queued.

I tested what would happen if we do not flush queued packets and was
trivially able to obtain the oops below.  All that was required was
to stop the nf_queue listening process, to delete all of the nf_tables,
and to awaken the nf_queue listening process.

macvtap: Increase limit of macvtap queues · dfe816c5

由 Pankaj Gupta 提交于 6月 19, 2015

Macvtap should be compatible with tuntap for
maximum number of queues.

commit 'baf71c5c (tuntap:
Increase the number of queues in tun.)' removes
the limitations and increases number of queues in tuntap.
Now, Its safe to increase number of queues in Macvtap as well.

This patch also modifies 'macvtap_del_queues' function
to avoid extra memory allocation in stack.

Changes from v1->v2 :
Michael S. Tsirkin, Jason Wang  :
                  Better way to use linked list to
avoid use of extra memory in stack.

bpf: BPF based latency tracing · 0fb1170e

由 Daniel Wagner 提交于 6月 19, 2015

BPF offers another way to generate latency histograms. We attach
kprobes at trace_preempt_off and trace_preempt_on and calculate the
time it takes to from seeing the off/on transition.

The first array is used to store the start time stamp. The key is the
CPU id. The second array stores the log2(time diff). We need to use
static allocation here (array and not hash tables). The kprobes
hooking into trace_preempt_on|off should not calling any dynamic
memory allocation or free path. We need to avoid recursivly
getting called. Besides that, it reduces jitter in the measurement.

bridge: multicast: start querier timer when running user-space stp · 7ce42de1

由 Nikolay Aleksandrov 提交于 6月 19, 2015

When STP is running in user-space and querier is configured, the
querier timer is not started when a port goes to a non-blocking state.
This patch unifies the user- and kernel-space stp multicast port enable
path and enables it in all states different from blocking. Note that when a
port goes in BR_STATE_DISABLED it's not enabled because that is handled
in the beginning of the port list loop.

Actor and Partner details can be accessed via proc-fs, sys-fs
entries or netlink interface. These interfaces are world readable
at this moment. The earlier patch-series made the LACP communication
secure to avoid nuisance attack from within the same L2 domain but
it did not prevent "someone unprivileged" looking at that information
on host and perform the same act.

This patch essentially avoids spitting those entries if the user
in question does not have enough privileges.

netlink: add API to retrieve all group memberships · b42be38b

由 David Herrmann 提交于 6月 17, 2015

This patch adds getsockopt(SOL_NETLINK, NETLINK_LIST_MEMBERSHIPS) to
retrieve all groups a socket is a member of. Currently, we have to use
getsockname() and look at the nl.nl_groups bitmask. However, this mask is
limited to 32 groups. Hence, similar to NETLINK_ADD_MEMBERSHIP and
NETLINK_DROP_MEMBERSHIP, this adds a separate sockopt to manager higher
groups IDs than 32.

This new NETLINK_LIST_MEMBERSHIPS option takes a pointer to __u32 and the
size of the array. The array is filled with the full membership-set of the
socket, and the required array size is returned in optlen. Hence,
user-space can retry with a properly sized array in case it was too small.

When an inet_sock is destroyed, its source port (sk_num) is set to
zero as part of the unhash procedure.  In order to supply a source
port as part of the NETLINK_SOCK_DIAG socket destruction broadcasts,
the source port number must be read from inet_sport instead.

Netfilter updates for net-next

The following patchset contains a final Netfilter pull request for net-next
4.2. This mostly addresses some fallout from the previous pull request, small
netns updates and a couple of new features for nfnetlink_log and the socket
match that didn't get in time for the previous pull request. More specifically
they are:

1) Add security context information to nfnetlink_queue, from Roman Kubiak.

2) Add support to restore the sk_mark into skb->mark through xt_socket,
   from Harout Hedeshian.

3) Force alignment of 16 bytes of per cpu xt_counters, from Eric Dumazet.

4) Rename br_netfilter.c to br_netfilter_hooks.c to prepare split of IPv6 code
   into a separated file.

5) Move the IPv6 code in br_netfilter into a separated file.

6) Remove unused RCV_SKB_FAIL() in nfnetlink_queue and nfetlink_log, from Eric
   Biederman.

7) Two liner to simplify netns logic in em_ipset_match().

8) Add missing includes to net/net_namespace.h to avoid compilation problems
   that result from not including linux/netfilter.h in netns headers.

9) Use a forward declaration instead of including linux/proc_fs.h from
   netns/netfilter.h

10) Add a new linux/netfilter_defs.h to replace the linux/netfilter.h inclusion
    in netns headers.

11) Remove spurious netfilter.h file included in the net tree, also from Eric
    Biederman.

12) Fix x_tables compilation warnings on 32 bits platforms that resulted from
    recent changes in x_tables counters, from Florian Westphal.
