8 years agoaf_unix: Avoid socket->sk NULL OOPS in stream connect security hooks.
David S. Miller [Wed, 5 Jan 2011 23:38:53 +0000]
af_unix: Avoid socket->sk NULL OOPS in stream connect security hooks.

unix_release() can asynchornously set socket->sk to NULL, and
it does so without holding the unix_state_lock() on "other"
during stream connects.

However, the reverse mapping, sk->sk_socket, is only transitioned
to NULL under the unix_state_lock().

Therefore make the security hooks follow the reverse mapping instead
of the forward mapping.

8 years agonet_sched: pfifo_head_drop problem
Eric Dumazet [Wed, 5 Jan 2011 10:35:02 +0000]
net_sched: pfifo_head_drop problem

commit 57dbb2d83d100ea (sched: add head drop fifo queue)
introduced pfifo_head_drop, and broke the invariant that
sch->bstats.bytes and sch->bstats.packets are COUNTER (increasing
counters only)

This can break estimators because est_timer() handles unsigned deltas
only. A decreasing counter can then give a huge unsigned delta.

My mid term suggestion would be to change things so that
sch->bstats.bytes and sch->bstats.packets are incremented in dequeue()
only, not at enqueue() time. We also could add drop_bytes/drop_packets
and provide estimations of drop rates.

It would be more sensible anyway for very low speeds, and big bursts.
Right now, if we drop packets, they still are accounted in byte/packets
abolute counters and rate estimators.

Before this mid term change, this patch makes pfifo_head_drop behavior
similar to other qdiscs in case of drops :
Dont decrement sch->bstats.bytes and sch->bstats.packets

ipv4/route.c: respect prefsrc for local routes

The preferred source address is currently ignored for local routes,
which results in all local connections having a src address that is the
same as the local dst address. Fix this by respecting the preferred source
address when it is provided for local routes.

This bug can be demonstrated as follows:

 # ifconfig dummy0 192.168.0.1
 # ip route show table local | grep local.*dummy0
 local 192.168.0.1 dev dummy0  proto kernel  scope host  src 192.168.0.1
 # ip route change table local local 192.168.0.1 dev dummy0 \
     proto kernel scope host src 127.0.0.1
 # ip route show table local | grep local.*dummy0
 local 192.168.0.1 dev dummy0  proto kernel  scope host  src 127.0.0.1

We now establish a local connection and verify the source IP
address selection:

 # nc -l 192.168.0.1 3128 &
 # nc 192.168.0.1 3128 &
 # netstat -ant | grep 192.168.0.1:3128.*EST
 tcp        0      0 192.168.0.1:3128        192.168.0.1:33228 ESTABLISHED

Yes, why not, I am only wondering why loopback / dummy (and others ?)
only set NETIF_F_TSO :)

Since I want to play with ECN, I might also add NETIF_F_TSO_ECN ;)

For other flags, I really doubt it can matter on ifb ?

IFB can use the full set of features flags (NETIF_F_SG |
NETIF_F_FRAGLIST | NETIF_F_TSO | NETIF_F_NO_CSUM | NETIF_F_HIGHDMA) to
avoid unnecessary split of some packets (GRO for example)

Changli suggested to also set vlan_features, NETIF_F_TSO6,
NETIF_F_TSO_ECN.

8 years agonetdev: Update status of 8390 based drivers in MAINTAINERS
Paul Gortmaker [Sat, 1 Jan 2011 13:28:30 +0000]
netdev: Update status of 8390 based drivers in MAINTAINERS

With the original 8 bit ISA ne1000 card being over 20 years old, it
only makes sense to consider ne.c and all the other toplevel 8390
based driver files as legacy for obsolete hardware.  The most
recent thing made in large quantities that was 8390 based were
those crazy PCI ne2k clones - and even they are now 10+ years old.

Also remove myself as maintainer, since the only changes to these
drivers going forward will be the generic API type changes that
touch all drivers.

J. K. Cliburn [Sat, 1 Jan 2011 05:02:12 +0000]
atl1: fix oops when changing tx/rx ring params

Commit 3f5a2a713aad28480d86b0add00c68484b54febc zeroes out the statistics
message block (SMB) and coalescing message block (CMB) when adapter ring
resources are freed.  This is desirable behavior, but, as a side effect,
the commit leads to an oops when atl1_set_ringparam() attempts to alter
the number of rx or tx elements in the ring buffer (by using ethtool
-G, for example).  We don't want SMB or CMB to change during this
operation.

Modify atl1_set_ringparam() to preserve SMB and CMB when changing ring
parameters.

so they are subject to carry races.

NB:
  * TX/RX counters are maintained in software because the the hardware packet count
    is only a 32 bit value.

Hi,

In drivers/isdn/gigaset/capi.c::do_disconnect_req() we will leak the
memory allocated (with kmalloc) to 'b3cmsg' if the call to alloc_skb()
fails.

...
b3cmsg = kmalloc(sizeof(*b3cmsg), GFP_KERNEL);
allocation here ------^
if (!b3cmsg) {
dev_err(cs->dev, "%s: out of memory\n", __func__);
send_conf(iif, ap, skb, CAPI_MSGOSRESOURCEERR);
return;
}
capi_cmsg_header(b3cmsg, ap->id, CAPI_DISCONNECT_B3, CAPI_IND,
 ap->nextMessageNumber++,
 cmsg->adr.adrPLCI | (1 << 16));
b3cmsg->Reason_B3 = CapiProtocolErrorLayer1;
b3skb = alloc_skb(CAPI_DISCONNECT_B3_IND_BASELEN, GFP_KERNEL);

send_conf(iif, ap, skb, CAPI_MSGOSRESOURCEERR);
return;

This leak is easily fixed by just kfree()'ing the memory allocated to
'b3cmsg' right before we return. The following patch does that.

dcbnl: add appliction tlv handlers

This patch adds application tlv handlers. Networking stacks
may use the application priority to set the skb priority of
their stack using the negoatiated dcbx priority.

This patch provides the dcb_{get|set}app() routines for the
stack to query these parameters. Notice lower layer drivers
can use the dcbnl_ops routines if additional handling is
needed. Perhaps in the firmware case for example

8 years agodcbnl: add support for ieee8021Qaz attributes
John Fastabend [Thu, 30 Dec 2010 09:25:46 +0000]
dcbnl: add support for ieee8021Qaz attributes

The IEEE8021Qaz is the IEEE standard version of CEE. The
standard has had enough significant changes from the CEE
version that many of the CEE attributes have no meaning
in the new spec or do not easily map to IEEE standards.

Rather then attempt to create a complicated mapping
between CEE and IEEE standards this patch adds a nested
IEEE attribute to the list of DCB attributes. The policy
is,

[DCB_ATTR_IFNAME]
[DCB_ATTR_STATE]
...
[DCB_ATTR_IEEE]
[DCB_ATTR_IEEE_ETS]
[DCB_ATTR_IEEE_PFC]
[DCB_ATTR_IEEE_APP_TABLE]
[DCB_ATTR_IEEE_APP]
...

The following dcbnl_rtnl_ops routines were added to handle
the IEEE standard,

int (*ieee_getets) (struct net_device *, struct ieee_ets *);
int (*ieee_setets) (struct net_device *, struct ieee_ets *);
int (*ieee_getpfc) (struct net_device *, struct ieee_pfc *);
int (*ieee_setpfc) (struct net_device *, struct ieee_pfc *);

8 years agoppp: allow disabling multilink protocol ID compression
stephen hemminger [Mon, 20 Dec 2010 17:58:33 +0000]
ppp: allow disabling multilink protocol ID compression

Linux would not connect to other router running old version Cisco IOS (12.0).
This is most likely a bug in that version of IOS, since it is fixed
in later versions. As a workaround this patch allows a module parameter
to be set to disable compressing the protocol ID.

See: https://bugzilla.vyatta.com/show_bug.cgi?id=3979

RFC 1990 allows an implementation to formulate MP fragments as if protocol
compression had been negotiated.  This allows us to always send compressed
protocol IDs.  But some implementations don't accept MP fragments with
compressed protocol IDs.  This parameter allows us to interoperate with
them.  The default value of the configurable parameter is the same as the
current behavior:  protocol compression is enabled.  If protocol compression
is disabled we will not send compressed protocol IDs.

This is based on an earlier patch by Bob Gilligan (using a sysctl).
Module parameter is writable to allow for enabling even if ppp
is already loaded for other uses.

8 years agoueagle-atm: fix PHY signal initialization race
Dan Williams [Sun, 19 Dec 2010 08:17:50 +0000]
ueagle-atm: fix PHY signal initialization race

A race exists when initializing ueagle-atm devices where the generic atm
device may not yet be created before the driver attempts to initialize
it's PHY signal state, which checks whether the atm device has been
created or not.  This often causes the sysfs 'carrier' attribute to be
'1' even though no signal has actually been found.

uea_probe
   usbatm_usb_probe
      driver->bind (uea_bind)
         uea_boot
            kthread_run(uea_kthread)     uea_kthread
      usbatm_atm_init                       uea_start_reset
         atm_dev_register                      UPDATE_ATM_SIGNAL

UPDATE_ATM_SIGNAL checks whether the ATM device has been created and if
not, will not update the PHY signal state.  Because of the race that
does not always happen in time, and the PHY signal state remains
ATM_PHY_SIG_FOUND even though no signal exists.

To fix the race, just create the kthread during initialization, and only
after initialization is complete, start the thread that reboots the
device and initializes PHY state.
