The dynamic entries are right-aligned unlike other entries since it
usually has numeric value. But for the hierarchy mode, left alignment
is more appropriate IMHO. Also trim spaces on the left so that we can
easily identify the hierarchy.

When dynamic entries are used in the hierarchy mode with multiple
events, the output might not be aligned properly. In the hierarchy
mode, the each sort column is indented using total number of sort keys.
So it keeps track of number of sort keys when adding them. However
a dynamic sort key can be added more than once when multiple events have
same field names. This results in unnecessarily long indentation in the
output.
For example perf kmem records following events:
$ perf evlist --trace-fields -i perf.data.kmem
kmem:kmalloc: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags
kmem:kmalloc_node: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags,node
kmem:kfree: trace_fields: call_site,ptr
kmem:kmem_cache_alloc: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags
kmem:kmem_cache_alloc_node: trace_fields: call_site,ptr,bytes_req,bytes_alloc,gfp_flags,node
kmem:kmem_cache_free: trace_fields: call_site,ptr
kmem:mm_page_alloc: trace_fields: page,order,gfp_flags,migratetype
kmem:mm_page_free: trace_fields: page,order
As you can see, many field names shared between kmem events. So adding
'ptr' dynamic sort key alone will set nr_sort_keys to 6. And this adds
many unnecessary spaces between columns.

$ perf report -i perf.data.kmem --hierarchy -s ptr -g none --stdio

When hist_entry__cmp() and hist_entry__collapse() are called, they
should check if the dynamic entry is comparing matching hists only.
Otherwise it might access different hists resulting in incorrect output.

When the send skbuff reaches the end, nlmsg_put and friends returns
-EMSGSIZE but it is silently thrown away in ndo_fdb_dump. It is called
within a for_each_netdev loop and the first fdb entry of a following

of cb->args[0] and idx to keep track of the entries that are already

1GbE Intel Wired LAN Driver Updates 2016-02-24
This series contains updates to e1000e, igb and igbvf.
Raanan provides updates for e1000e, first increases the ULP timer since it
now takes longer for the ULP exit to complete on Skylake. Fixes the
configuration of the internal hardware PHY clock gating mechanism, which was
causing packet loss due to mis configuring. Fixed additional ULP
configuration settings which were not being properly cleared after cable
connect in V-Pro capable systems. Added support for more i219 devices.
Takuma Ueba provides a fix for I210 where IPv6 autoconf test sometimes
fails due to DAD NS for link-local is not transmitted. To avoid this
issue, we need to wait until 1000BASE-T status register "Remote receiver
status OK".
Todd provides a patch to override EEPROM WoL settings for specific OEM
devices. Then renamed igb defines to be more generic, since the define
E1000_MRQC_ENABLE_RSS_4Q enables 4 and 8 queues depending on the part.
Roland Hii fixes an issue where only the half cycle time of less than or
equal to 70 millisecond uses the I210 clock output function. His patch
adds additional conditions when half cycle time is equal to 125 or 250 or
500 millisecond to use the clock output function.
Alex Duyck adds support for generic transmit checksums for igb and igbvf.
Jon Maxwell fixes an issues where customer applications are registering
and un-registering multicast addresses every few seconds which is leading
to many "Link is up" messages in the logs as a result of the
netif_carrier_off(netdev) in igbvf_msix_other(). So remove the
link is up message when registering multicast addresses.
Corinna Vinschen provides a fix for when switching off VLAN offloading on
i350, the VLAN interface becomes unusable.
Stefan Assmann updates the driver to use ndo_stop() instead of
dev_close() when running ethtool offline self test. Since dev_close()
causes IFF_UP to be cleared which will remove the interfaces routes
and some addresses.
v2: Dropped patches 6-10 in the original series. Patch 6-7 added support
for character device for AVB and based on community feedback, we do not
want to do this. Patches 8-10 provided fixes to the problematic code
added in patches 6 & 7. So all of them must go!

For now, flow of GCing an encrypted data page:
1) try to grab meta page in meta inode's mapping with index of old block
address of that data page
2) load data of ciphertext into meta page
3) allocate new block address
4) write the meta page into new block address
5) update block address pointer in direct node page.
Other reader/writer will use f2fs_wait_on_encrypted_page_writeback to
check and wait on GCed encrypted data cached in meta page writebacked
in order to avoid inconsistence among data page cache, meta page cache
and data on-disk when updating.
However, we will use new block address updated in step 5) as an index to
lookup meta page in inner bio buffer. That would be wrong, and we will
never find the GCing meta page, since we use the old block address as
index of that page in step 1).
This patch fixes the issue by adjust the order of step 1) and step 3),
and in step 1) grab page with index generated in step 3).

On reviewing the code I realized that GRE and UDP tunnels could cause a
kernel panic if we used GSO to segment a large UDP frame that was sent
through the tunnel with an outer checksum and hardware offloads were not
available.
In order to correct this we need to update the feature flags that are
passed to the skb_segment function so that in the event of UDP
fragmentation being requested for the inner header the segmentation
function will correctly generate the checksum for the payload if we cannot
segment the outer header.

net: l3mdev: Fix source address for unnumbered deployments
David Lamparter noted a use case where the source address selection fails
to pick an address from a VRF interface - unnumbered interfaces. The use
case has the VRF device as the VRF local loopback with addresses and
interfaces enslaved without an address themselves. e.g,
ip addr add 9.9.9.9/32 dev lo
ip link set lo up
ip link add name vrf0 type vrf table 101
ip rule add oif vrf0 table 101
ip rule add iif vrf0 table 101
ip link set vrf0 up
ip addr add 10.0.0.3/32 dev vrf0
ip link add name dummy2 type dummy
ip link set dummy2 master vrf0 up
--> note dummy2 has no address - unnumbered device
ip route add 10.2.2.2/32 dev dummy2 table 101
ip neigh add 10.2.2.2 dev dummy2 lladdr 02:00:00:00:00:02
ping to the 10.2.2.2 through the L3 domain:
$ ping -I vrf0 -c1 10.2.2.2
ping: Warning: source address might be selected on device other than vrf0.
PING 10.2.2.2 (10.2.2.2) from 9.9.9.9 vrf0: 56(84) bytes of data.
picks up the wrong address -- the one from 'lo' not vrf0. And from tcpdump:
12:57:29.449128 IP 9.9.9.9 > 10.2.2.2: ICMP echo request, id 2491, seq 1, length 64
This patch series changes address selection to only consider devices in
the same L3 domain and to use the VRF device as the L3 domains loopback.
$ ping -I vrf0 -c1 10.2.2.2
PING 10.2.2.2 (10.2.2.2) from 10.0.0.3 vrf0: 56(84) bytes of data.
From tcpdump:
12:59:25.096426 IP 10.0.0.3 > 10.2.2.2: ICMP echo request, id 2113, seq 1, length 64
Now the source address comes from vrf0.

When selecting an address in context of a VRF, the vrf master should be
preferred for address selection. If it isn't, the user has a hard time
getting the system to select to their preference - the code will pick
the address off the first in-VRF interface it can find, which on a
router could well be a non-routable address.

David Lamparter noted a use case where the source address selection fails
to pick an address from a VRF interface - unnumbered interfaces.
Relevant commands from his script:
ip addr add 9.9.9.9/32 dev lo
ip link set lo up
ip link add name vrf0 type vrf table 101
ip rule add oif vrf0 table 101
ip rule add iif vrf0 table 101
ip link set vrf0 up
ip addr add 10.0.0.3/32 dev vrf0
ip link add name dummy2 type dummy
ip link set dummy2 master vrf0 up
--> note dummy2 has no address - unnumbered device
ip route add 10.2.2.2/32 dev dummy2 table 101
ip neigh add 10.2.2.2 dev dummy2 lladdr 02:00:00:00:00:02
tcpdump -ni dummy2 &
And using ping instead of his socat example:
$ ping -I vrf0 -c1 10.2.2.2
ping: Warning: source address might be selected on device other than vrf0.
PING 10.2.2.2 (10.2.2.2) from 9.9.9.9 vrf0: 56(84) bytes of data.
>From tcpdump:
12:57:29.449128 IP 9.9.9.9 > 10.2.2.2: ICMP echo request, id 2491, seq 1, length 64
Note the source address is from lo and is not a VRF local address. With
this patch:
$ ping -I vrf0 -c1 10.2.2.2
PING 10.2.2.2 (10.2.2.2) from 10.0.0.3 vrf0: 56(84) bytes of data.
>From tcpdump:
12:59:25.096426 IP 10.0.0.3 > 10.2.2.2: ICMP echo request, id 2113, seq 1, length 64
Now the source address comes from vrf0.
The ipv4 function for selecting source address takes a const argument.
Removing the const requires touching a lot of places, so instead
l3mdev_master_ifindex_rcu is changed to take a const argument and then
do the typecast to non-const as required by netdev_master_upper_dev_get_rcu.
This is similar to what l3mdev_fib_table_rcu does.
IPv6 for unnumbered interfaces appears to be selecting the addresses
properly.
