Default Bug#585770: a collection of NULL pointer dereference

Package: linux-2.6
Version: 2.6.32-15
Severity: normal

Hi,

cimarosa.d.o runs linux-image-2.6.32-bpo.3-amd64 (from 2.6.32-9) just
fine.

However, it does not boot with linux-image-2.6.32-bpo.5-amd64
(2.6.32-15):

During boot up, when init brings up the network we get various different
kernel NULL pointer dereferences. Cimarosa has a lo, an eth0 and an
eth0.221 vlan device. If the eth0.221 is not configured to be brought
up on boot then the system boots correctly, and bringing up the
interface later also appears to work without any ill effects. So
there might be some racy thing going on.

It'd be pretty sweet if cimarosa could be made to work with a recent
debian kernel.


[I can re-run these tests with the real debian.org 2.6.32-5 instead of
the bpo one, but given that the serial console on this monster is very
unreliably and only works once every 10 to 20 tries for grub purposes
I'd rather not unless you feel it's important.]


Longish serial console logs to follow:

Version where the vlan is brought up later:

| 0xffffffff812b7581 <+44>: cmpb $0xff,0x18(%rcx)

%rdi is the skb argument, %rcx seems to be not initialized (but as this
function is static, the compiler can use that knowledge).

It is initialised; a destination of %ecx really means %rcx with
zero-extension.

Matching this up with the source:

struct dst_entry *dst = skb_dst(skb);
0xffffffff812b7562 <+13>: mov 0x28(%rdi),%rax

struct net_device *dev = dst->dev;
0xffffffff812b7573 <+30>: mov 0x18(%rax),%r13

skb->protocol = htons(ETH_P_IPV6);
0xffffffff812b7577 <+34>: movw $0xdd86,0x7e(%rdi)

skb->dev = dev;
0xffffffff812b757d <+40>: mov %r13,0x20(%rdi)

if (ipv6_addr_is_multicast(&ipv6_hdr(skb)->daddr)) {
[ipv6_hdr(skb) defined as (struct ipv6hdr *)(skb->head + skb->network_header)]
[ipv6_addr_is_multicast(addr) defined as (addr->s6_addr32[0] & htonl(0xFF000000)) == htonl(0xFF000000)]
0xffffffff812b7566 <+17>: mov 0xc0(%rdi),%ecx
0xffffffff812b756c <+23>: add 0xd0(%rdi),%rcx
0xffffffff812b7581 <+44>: cmpb $0xff,0x18(%rcx)

So skb->head (or possibly skb->network_header) was invalid here.

Looking at the other oops:

__be16 type = hh->hh_type;
ffe7: 8b 56 40 mov 0x40(%rsi),%edx

struct ethhdr *eth;
const struct net_device *dev = neigh->dev;
ffed: 4c 8b 47 18 mov 0x18(%rdi),%r8

eth = (struct ethhdr *)
(((u8 *) hh->hh_data) + (HH_DATA_OFF(sizeof(*eth))));
fff8: 48 8d 4e 5a lea 0x5a(%rsi),%rcx

if (type == htons(ETH_P_802_3))
return -1;
ffea: 83 c8 ff or $0xffffffffffffffff,%eax
fff1: 66 81 fa 00 01 cmp $0x100,%dx
fff6: 74 31 je 0x10029

eth->h_proto = type;
fffc: 66 89 51 0c mov %dx,0xc(%rcx)

memcpy(eth->h_source, dev->dev_addr, ETH_ALEN);
10000: 49 8b 90 20 02 00 00 mov 0x220(%r8),%rdx
10007: 8b 02 mov (%rdx),%eax
10009: 89 46 60 mov %eax,0x60(%rsi)
1000c: 66 8b 42 04 mov 0x4(%rdx),%ax
10010: 66 89 46 64 mov %ax,0x64(%rsi)

So neigh->dev was NULL here.

Could you try reverting the patch
bugfix/all/vlan-macvlan-propagate-transmission-state-to-upper-layer.patch ?

Instructions for rebuilding the official kernel packages are at
<http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official>.

That appears to have helped.

Was the crash reliably reproducible, so you can be confident that this
change fixed it?

It always crashed in what was probably 10 attempts to boot the machine,
and did not die in 2 reboots after reverting that patch.
