bonding: Display LACP info only to CAP_NET_ADMIN capable user
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.

limited to 32 groups. Hence, similar to NETLINK_ADD_MEMBERSHIP and

This new NETLINK_LIST_MEMBERSHIPS option takes a pointer to __u32 and 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.

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.

The remove_advertising() and remove_advertising_complete() functions

remove_advertising() is refactored to use the new dynamic advertising

Merge branch 'master' of git://git./linux/kernel/git/jkirsher/next-queue

====================
This series contains updates to fm10k only.
Alex provides two fixes for the fm10k, first folds the fm10k_pull_tail()
call into fm10k_add_rx_frag(), this way the fragment does not have to be
modified after it is added to the skb. The second fixes missing braces
to an if statement.
The remaining patches are from Jacob which contain improvements and fixes
for fm10k. First fix makes it so that invalid address will simply be
skipped and allows synchronizing the full list to proceed with using
iproute2 tool. Fixed a possible kernel panic by using the correct
transmit timestamp function. Simplified the code flow for setting the
IN_PROGRESS bit of the shinfo for an skb that we will be timestamping.
Fix a bug in the timestamping transmit enqueue code responsible for a
NULL pointer dereference and invalid access of the skb list by freeing
the clone in the cases where we did not add it to the queue. Update the
PF code so that it resets the empty TQMAP/RQMAP regirsters post-VFLR to
prevent innocent VF drivers from triggering malicious driver events.
The SYSTIME_CFG.Adjust direction bit is actually supposed to indicate
that the adjustment is positive, so fix the code to align correctly with
the hardware and documentation. Cleanup local variable that is no longer
used after a previous refactor of the code. Fix the code flow so that we
actually clear the enabled flag as part of our removal of the LPORT.

fm10k: remove extraneous NULL check on l2_accel
l2_accel was checked for NULL at the top of fm10k_dfwd_del_station, and
we return if it is not defined. Due to this, we already know it can't be
null here so a separate check is meaningless. Discovered via cppcheck.

fm10k: add call to fm10k_clean_all_rx_rings in fm10k_down
This prevents a memory leak in fm10k_set_ringparams. The leak occurs
because we go down, change ring parameters, and then come up. However,
fm10k_down on its own is not clearing the Rx rings. Since fm10k_up
assumes the rings are clean we basically drop the buffers and leak a
bunch of memory. Eventually we hit dirty page faults and reboot the
system. This issue does not occur elsewhere because other flows that
involve fm10k_down go through fm10k_close which immediately called
fm10k_free_all_rx_resources which properly cleans the rings.

fm10k: fix incorrect free on skb in ts_tx_enqueue
This patch resolves a bug in the ts_tx_enqueue code responsible for a
NULL pointer dereference and invalid access of the skb list. We
incorrectly freed the actual skb we found instead of our copy. Thus the
skb queue is essentially invalidated. Resolve this by freeing our clone
in the cases where we did not add it to the queue. This also avoids the
skb memory leak caused by failure to free the clone.

fm10k: use correct ethernet driver Tx timestamp function
skb_complete_tx_timestamp is intended for use by PHY drivers which
implement a different method of returning timestamps. This method is
intended to be used after a PHY driver accepts a cloned packet via its

ethernet driver such as fm10k. This patch fixes the following possible

fm10k: ignore invalid multicast address entries
This change fixes an issue with adding an invalid multicast address
using the iproute2 tool (ip maddr add <MADDR> dev <dev>). The iproute2
tool and the kernel do not validate or filter the multicast addresses
when adding them to the multicast list. Thus, when synchronizing this
list with an invalid entry, the action will be aborted with an error
since the fm10k driver currently validates the list. Consequently,
multicast entries beyond the invalid one will not be processed and
communicated with the switch via the mailbox. This change makes it so
that invalid addresses will simply be skipped and allows synchronizing
the full list to proceed.
