netfilter: nf_conntrack: make sequence number adjustments usuable without NAT

Split out sequence number adjustments from NAT and move them to the conntrack
core to make them usable for SYN proxying. The sequence number adjustment
information is moved to a seperate extend. The extend is added to new
conntracks when a NAT mapping is set up for a connection using a helper.

As a side effect, this saves 24 bytes per connection with NAT in the common
case that a connection does not have a helper assigned.

with the tcp-reset option sends out reset packets with the src MAC address
of the local bridge interface, instead of the MAC address of the intended

11 years agonet: tcp_probe: allow more advanced ingress filtering by mark
Daniel Borkmann [Fri, 23 Aug 2013 14:16:33 +0000 (16:16 +0200)]
net: tcp_probe: allow more advanced ingress filtering by mark

Currently, the tcp_probe snooper can either filter packets by a given
port (handed to the module via module parameter e.g. port=80) or lets
all TCP traffic pass (port=0, default). When a port is specified, the
port number is tested against the sk's source/destination port. Thus,
if one of them matches, the information will be further processed for
the log.

As this is quite limited, allow for more advanced filtering possibilities
which can facilitate debugging/analysis with the help of the tcp_probe
snooper. Therefore, similarly as added to BPF machine in commit 7e75f93e
("pkt_sched: ingress socket filter by mark"), add the possibility to
use skb->mark as a filter.

If the mark is not being used otherwise, this allows ingress filtering
by flow (e.g. in order to track updates from only a single flow, or a
subset of all flows for a given port) and other things such as dynamic
logging and reconfiguration without removing/re-inserting the tcp_probe
module, etc. Simple example:

  insmod net/ipv4/tcp_probe.ko fwmark=8888 full=1
  ...
  iptables -A INPUT -i eth4 -t mangle -p tcp --dport 22 \
           --sport 60952 -j MARK --set-mark 8888
  [... sampling interval ...]
  iptables -D INPUT -i eth4 -t mangle -p tcp --dport 22 \
           --sport 60952 -j MARK --set-mark 8888

The current option to filter by a given port is still being preserved. A
similar approach could be done for the sctp_probe module as a follow-up.

drivers/platform/olpc/olpc-ec.c: initialise earlier

Being a low-level component, various drivers (e.g.  olpc-battery) assume
that it is ok to communicate with the OLPC Embedded Controller during
probe.  Therefore the OLPC EC driver must be initialised before other
drivers try to use it.  This was the case until it was recently moved
out of arch/x86 and restructured around commits ac2504151f5a ("Platform:
OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86:
OLPC: switch over to using new EC driver on x86").

Use arch_initcall so that olpc-ec is readied earlier, matching the
previous behaviour.

Fixes a regression introduced in Linux-3.6 where various drivers such as
olpc-battery and olpc-xo1-sci failed to load due to an inability to
communicate with the EC.  The user-visible effect was a lack of battery
monitoring, missing ebook/lid switch input devices, etc.

11 years agotcp: increase throughput when reordering is high
Yuchung Cheng [Thu, 22 Aug 2013 00:29:23 +0000 (17:29 -0700)]
tcp: increase throughput when reordering is high

The stack currently detects reordering and avoid spurious
retransmission very well. However the throughput is sub-optimal under
high reordering because cwnd is increased only if the data is deliverd
in order. I.e., FLAG_DATA_ACKED check in tcp_ack().  The more packet
are reordered the worse the throughput is.

Therefore when reordering is proven high, cwnd should advance whenever
the data is delivered regardless of its ordering. If reordering is low,
conservatively advance cwnd only on ordered deliveries in Open state,
and retain cwnd in Disordered state (RFC5681).

Using netperf on a qdisc setup of 20Mbps BW and random RTT from 45ms
to 55ms (for reordering effect). This change increases TCP throughput
by 20 - 25% to near bottleneck BW.

A special case is the stretched ACK with new SACK and/or ECE mark.
For example, a receiver may receive an out of order or ECN packet with
unacked data buffered because of LRO or delayed ACK. The principle on
such an ACK is to advance cwnd on the cummulative acked part first,
then reduce cwnd in tcp_fastretrans_alert().

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates

This series contains updates to igb and e1000e.

Akeem provides 3 igb patches, the first resets the link when EEE is enabled
or disabled if the link is up.  His second patch changes a register read
which normally stores of the read value to "just-read" so that hardware
can accurately latch the register read.  Lastly, he adds rcu_lock to avoid
a possible race condition with igb_update_stats function.

Mitch provides a fix for SR-IOV, where MSI-X interrupts are required, so
make sure that MSI-X is enabled before allowing the user to turn on SR-IOV.

Alex's igb patch make it so that we limit the lower bound for max_frame_size
to the size of a standard Ethernet frame.  This allows for feature parity
with other Intel based drivers such as ixgbe.

Carolyn adds a SKU for a flashless i210 device and a fix for get_fw_version()
so that it works for all parts for igb.  In addition, she has 2 igb patches
to refactor NVM code to accommodate devices with no flash.  Lastly, she
adds code to check for the failure of pci_disable_link_state() to attempt
to work around a problem found with some systems.

Laura provides the remaining 2 igb patches.  One removing the hard-coded
value for the size of the RETA indirection table, and creates a macro instead
for the RETA indirection table.  The second adds the ethtool callbacks
necessary to change the RETA indirection table from userspace.

Bruce fixes a whitespace issue in a recent commit and resolves a jiffies
comparison warning by using time_after().

Li provides a fix for e1000e to avoid a kernel crash on shutdown by adding
one more check in e1000e_shutdown().  This is due to e1000e_shutdown()
trying to clear correctable errors on the upstream P2P bridge, when under
some cases we do not have the upstream P2P bridge.

v2:
 - fixed patch 11 conditional statement from < to <= based on feedback
   from Ben Hutchings
 - fixed patch 12 patch description (adding the commit summary) based

This reverts commit df54d6fa54275ce59660453e29d1228c2b45a826.

The commit isn't necessarily wrong, but because it recalculates the
random mmap_base every time, it seems to confuse user memory allocators
that expect contiguous mmap allocations even when the mmap address isn't
specified.

In particular, the MATLAB Java runtime seems to be unhappy. See

for that.  Revert this older commit in order to apply the other one.

Stephen Warren [Tue, 20 Aug 2013 20:00:13 +0000 (14:00 -0600)]
ARM: tegra: always enable USB VBUS regulators

This fixes a regression exposed during the merge window by commit
9f310de "ARM: tegra: fix VBUS regulator GPIO polarity in DT"; namely that
USB VBUS doesn't get turned on, so USB devices are not detected. This
affects the internal USB port on TrimSlice (i.e. the USB->SATA bridge, to
which the SSD is connected) and the external port(s) on Seaboard/
Springbank and Whistler.

The Tegra DT as written in v3.11 allows two paths to enable USB VBUS:

1) Via the legacy DT binding for the USB controller; it can directly
   acquire a VBUS GPIO and activate it.

2) Via a regulator for VBUS, which is referenced by the new DT binding
   for the USB controller.

Those two methods both use the same GPIO, and hence whichever of the
USB controller and regulator gets probed first ends up owning the GPIO.
In practice, the USB driver only supports path (1) above, since the
patches to support the new USB binding are not present until v3.12:-(

In practice, the regulator ends up being probed first and owning the
GPIO. Since nothing enables the regulator (the USB driver code is not
yet present), the regulator ends up being turned off. This originally
caused no problem, because the polarity in the regulator definition was
incorrect, so attempting to turn off the regulator actually turned it
on, and everything worked:-(

However, when testing the new USB driver code in v3.12, I noticed the
incorrect polarity and fixed it in commit 9f310de "ARM: tegra: fix VBUS
regulator GPIO polarity in DT". In the context of v3.11, this patch then
caused the USB VBUS to actually turn off, which broke USB ports with VBUS
control. I got this patch included in v3.11-rc1 since it fixed a bug in
device tree (incorrect polarity specification), and hence was suitable to
be included early in the rc series. I evidently did not test the patch at
all, or correctly, in the context of v3.11, and hence did not notice the
issue that I have explained above:-(

Fix this by making the USB VBUS regulators always enabled. This way, if
the regulator owns the GPIO, it will always be turned on, even if there
is no USB driver code to request the regulator be turned on. Even
ignoring this bug, this is a reasonable way to configure the HW anyway.

If this patch is applied to v3.11, it will cause a couple pretty trivial
conflicts in tegra20-{trimslice,seaboard}.dts when creating v3.12, since
the context right above the added lines changed in patches destined for
v3.12.

of: fdt: fix memory initialization for expanded DT

Already existing property flags are filled wrong for properties created from
initial FDT. This could cause problems if this DYNAMIC device-tree functions
are used later, i.e. properties are attached/detached/replaced. Simply dumping
flags from the running system show, that some initial static (not allocated via
kzmalloc()) nodes are marked as dynamic.

I putted some debug extensions to property_proc_show(..) :
..
+       if (OF_IS_DYNAMIC(pp))
+               pr_err("DEBUG: xxx : OF_IS_DYNAMIC\n");
+       if (OF_IS_DETACHED(pp))
+               pr_err("DEBUG: xxx : OF_IS_DETACHED\n");

when you operate on the nodes (e.g.: ~$ cat /proc/device-tree/*some_node*) you
will see that those flags are filled wrong, basically in most cases it will dump
a DYNAMIC or DETACHED status, which is in not true.
(BTW. this OF_IS_DETACHED is a own define for debug purposes which which just
make a test_bit(OF_DETACHED, &x->_flags)

If nodes are dynamic kernel is allowed to kfree() them. But it will crash
attempting to do so on the nodes from FDT -- they are not allocated via
kzmalloc().
