the NULL dereference is here:

 (gdb) list *0xffffffff804a9504
 0xffffffff804a9504 is in natsemi_poll (drivers/net/natsemi.c:717).
 712             return count;
 713     }
 714
 715     static inline void __iomem *ns_ioaddr(struct net_device *dev)
 716     {
 717             return (void __iomem *) dev->base_addr;
 718     }
 719

which is this code from natsemi.c:

 2227            struct net_device *dev = np->dev;
 2228            void __iomem * ioaddr = ns_ioaddr(dev);
 2229            int work_done = 0;

seems like the NAPI changes in -rc1 added an np->dev field but forgot to
initialize it ...

does the patch below fix the oops for you?

added np->dev to drivers/net/natsemi.c's struct netdev_private, but
forgot to initialize that new field upon driver init. The result was
a predictable NULL dereference oops the first time the hardware

ahci: ahci: implement workaround for ASUS P5W-DH Deluxe ahci_broken_hardreset(), take #2

P5W-DH Deluxe has ICH9 which doesn't have PMP support but SIMG 4726
hardwired to the second port of AHCI controller at PCI device 1f.2.
The 4726 doesn't work as PMP but as a storage processor which can do
hardware RAID on downstream ports.

When no device is attached to the downstream port of the 4726, pseudo
ATA device for configuration appears.  Unfortunately, ATA emulation on
the device is very lousy and causes long hang during boot.

This patch implements workaround for the board.  If the mainboard is
P5W-DH Deluxe (matched using DMI), only hardreset is used on the
second port of AHCI controller @ 1f.2 and the hardreset doesn't depend
on receiving the first FIS and just proceed to IDENTIFY.

Milton Miller [Wed, 24 Oct 2007 16:23:48 +0000 (18:23 +0200)] 
sched: fix sched_domain sysctl registration again

commit  029190c515f15f512ac85de8fc686d4dbd0ae731 (cpuset
sched_load_balance flag) was not tested SCHED_DEBUG enabled as
committed as it dereferences NULL when used and it reordered
the sysctl registration to cause it to never show any domains
or their tunables.

Fixes:

1) restore arch_init_sched_domains ordering
we can't walk the domains before we build them

presently we register cpus with empty directories (no domain
directories or files).

2) make unregister_sched_domain_sysctl do nothing when already unregistered
detach_destroy_domains is now called one set of cpus at a time
unregister_syctl dereferences NULL if called with a null.

While the the function would always dereference null if called
twice, in the previous code it was always called once and then
was followed a register.  So only the hidden bug of the
sysctl_root_table not being allocated followed by an attempt to
free it would have shown the error.

3) always call unregister and register in partition_sched_domains
The code is "smart" about unregistering only needed domains.
Since we aren't guaranteed any calls to unregister, always
unregister.   Without calling register on the way out we
will not have a table or any sysctl tree.

4) warn if register is called without unregistering
The previous table memory is lost, leaving pointers to the
later freed memory in sysctl and leaking the memory of the
tables.

Before this patch on a 2-core 4-thread box compiled for SMT and NUMA,
the domains appear empty (there are actually 3 levels per cpu).  And as
soon as two domains a null pointer is dereferenced (unreliable in this

17 years ago[CCID2/3]: Initialisation assignments of 0 are redundant
Gerrit Renker [Wed, 24 Oct 2007 12:53:01 +0000 (10:53 -0200)] 
[CCID2/3]: Initialisation assignments of 0 are redundant

Assigning initial values of `0' is redundant when loading a new CCID structure,
since in net/dccp/ccid.c the entire CCID structure is zeroed out prior to
initialisation in ccid_new():

     struct ccid {
     struct ccid_operations *ccid_ops;
     char        ccid_priv[0];
     };

     // ...
     if (rx) {
     memset(ccid + 1, 0, ccid_ops->ccid_hc_rx_obj_size);
     if (ccid->ccid_ops->ccid_hc_rx_init != NULL &&
         ccid->ccid_ops->ccid_hc_rx_init(ccid, sk) != 0)
     goto out_free_ccid;
     } else {
     memset(ccid + 1, 0, ccid_ops->ccid_hc_tx_obj_size);
     /* analogous to the rx case */

This patch therefore removes the redundant assignments. Thanks to Arnaldo for

[DCCP]: Convert Reset code into socket error number

This adds support for converting the 11 currently defined Reset codes into system
error numbers, which are stored in sk_err for further interpretation.

This makes the externally visible API behaviour similar to TCP, since a client
connecting to a non-existing port will experience ECONNREFUSED.

* Code 0, Unspecified, is interpreted as non-error (0);
* Code 1, Closed (normal termination), also maps into 0;
* Code 2, Aborted, maps into "Connection reset by peer" (ECONNRESET);
* Code 3, No Connection and
  Code 7, Connection Refused, map into "Connection refused" (ECONNREFUSED);
* Code 4, Packet Error, maps into "No message of desired type" (ENOMSG);
* Code 5, Option Error, maps into "Illegal byte sequence" (EILSEQ);
* Code 6, Mandatory Error, maps into "Operation not supported on transport endpoint" (EOPNOTSUPP);

* Code 11, Aggression Penalty, maps into "Quota exceeded" (EDQUOT)

17 years ago[DCCP]: One more exemption from full sequence number checks
Gerrit Renker [Wed, 24 Oct 2007 12:18:06 +0000 (10:18 -0200)] 
[DCCP]: One more exemption from full sequence number checks

This fixes the following problem: client connects to peer which has no DCCP
enabled or loaded; ICMP error messages ("Protocol Unavailable") can be seen
on the wire, but the application hangs. Reason: ICMP packets don't get through
to dccp_v4_err.

When reporting errors, a sequence number check is made for the DCCP packet
that had caused an ICMP error to arrive.
Such checks can not be made if the socket is in state LISTEN, RESPOND (which
in the implementation is the same as LISTEN), or REQUEST, since update_gsr()
has not been called in these states, hence the sequence window is 0..0.

This patch fixes the problem by adding the REQUEST state as another exemption
to the window check. The error reporting now works as expected on connecting.

[IPV4] ip_gre: sendto/recvfrom NBMA address

When GRE tunnel is in NBMA mode, this patch allows an application to use
a PF_PACKET socket to:
- send a packet to specific NBMA address with sendto()
- use recvfrom() to receive packet and check which NBMA address it came from

This is required to implement properly NHRP over GRE tunnel.

Convert mii (link state) monitor to acquire correct locks for
failover events.  In particular, failovers generally require RTNL at a low
level (when manipulating device MAC addresses, for example) and no other
locks.  The high level monitor is responsible for acquiring a known set
of locks, RTNL, the bond->lock for read and the slave_lock for write, and
the low level failover processing can then release appropriate locks as
needed.  This patch provides the high level portion.

As it is undesirable to acquire RTNL for every monitor pass (which
may occur as often as every 10 ms), the miimon has been converted to
do conditional locking.  A first pass inspects all slaves to determine
if any action is required, and if so, a second pass (after acquring RTNL)
is done to perform any actions (doing a complete rescan, as the situation
