I suspect this is a duplicate of #36 and specific to arm regardless of word size. |

Not really duplicate, but very much related. After all, arm/arm64 have separate Kconfig/Makefiles, and |

I'm quite certain that $ clang -target arm-linux-gnueabifh hello.c -c
$ llvm-objdump -D hello.o | grep ELF
hello.o: file format ELF32-arm-little
$ clang -target arm-linux-gnueabifh hello.c -c -mbig-endian

Compiling with
$ arm-linux-gnueabi-objdump -D init/main.o | rg arm

I don't quite get it, so what you are saying it works for you without changes to Linux (e.g. vanilla v4.19-rc4?). At least |
|
What did you set See clang's list of toolchain target triples: https://github.com/llvm-mirror/clang/blob/c3b3b46612df8dd7c293a331c804ad58ead65765/lib/Driver/ToolChains/Linux.cpp#L70 |

Yeah I think you're right about the linker since that patch doesn't solve this issue, I now get this: |

Closing this as fixed. @agners please confirm and reopen if this is still an issue for armv7. |

====================
fix dev null pointer dereference when send packets larger than mtu in collect_md mode
When we send a packet larger than PMTU, we need to reply with
icmp_send(ICMP_FRAG_NEEDED) or icmpv6_send(ICMPV6_PKT_TOOBIG).
But with collect_md mode, kernel will crash while accessing the dst dev
as __metadata_dst_init() init dst->dev to NULL by default. Here is what
the code path looks like, for GRE:
- ip6gre_tunnel_xmit
- ip6gre_xmit_ipv4
- __gre6_xmit
- ip6_tnl_xmit
- if skb->len - t->tun_hlen - eth_hlen > mtu; return -EMSGSIZE
- icmp_send
- net = dev_net(rt->dst.dev); <-- here
- ip6gre_xmit_ipv6
- __gre6_xmit
- ip6_tnl_xmit
- if skb->len - t->tun_hlen - eth_hlen > mtu; return -EMSGSIZE
- icmpv6_send
...
- decode_session4
- oif = skb_dst(skb)->dev->ifindex; <-- here
- decode_session6
- oif = skb_dst(skb)->dev->ifindex; <-- here
We could not fix it in __metadata_dst_init() as there is no dev supplied.
Look in to the __icmp_send()/decode_session{4,6} code we could find the dst
dev is actually not needed. In __icmp_send(), we could get the net by skb->dev.
For decode_session{4,6}, as it was called by xfrm_decode_session_reverse()
in this scenario, the oif is not used by
fl4->flowi4_oif = reverse ? skb->skb_iif : oif;
The reproducer is easy:
ovs-vsctl add-br br0
ip link set br0 up
ovs-vsctl add-port br0 gre0 -- set interface gre0 type=gre options:remote_ip=$dst_addr
ip link set gre0 up
ip addr add ${local_gre6}/64 dev br0
ping6 $remote_gre6 -s 1500
The kernel will crash like

v4: Julian Anastasov remind skb->dev also could be NULL in icmp_send. We'd
better still use dst.dev and do a check to avoid crash.
v3: only replace pkg to packets in cover letter. So I didn't update the version
info in the follow up patches.
v2: fix it in __icmp_send() and decode_session{4,6} separately instead of
updating shared dst dev in {ip_md, ip6}_tunnel_xmit.

The sanity check ("does the policy match the node") uses the prefix value of the node before its updated to the smaller value. To fix this, update the prefix earlier.

The debug_pagealloc functionality is useful to catch buggy page allocator users that cause e.g. use after free or double free. When page inconsistency is detected, debugging is often simpler by knowing the call stack of process that last allocated and freed the page. When page_owner is also enabled, we record the allocation stack trace, but not freeing. This patch therefore adds recording of freeing process stack trace to page owner info, if both page_owner and debug_pagealloc are configured and enabled. With only page_owner enabled, this info is not useful for the memory leak debugging use case. dump_page() is adjusted to print the info. An example result of calling __free_pages() twice may look like this (note the page last free stack trace): BUG: Bad page state in process bash pfn:13d8f8 page:ffffc31984f63e00 refcount:-1 mapcount:0 mapping:0000000000000000 index:0x0 flags: 0x1affff800000000() raw: 01affff800000000 dead000000000100 dead000000000122 0000000000000000 raw: 0000000000000000 0000000000000000 ffffffffffffffff 0000000000000000 page dumped because: nonzero _refcount page_owner tracks the page as freed page last allocated via order 0, migratetype Unmovable, gfp_mask 0xcc0(GFP_KERNEL) prep_new_page+0x143/0x150 get_page_from_freelist+0x289/0x380 __alloc_pages_nodemask+0x13c/0x2d0 khugepaged+0x6e/0xc10 kthread+0xf9/0x130 ret_from_fork+0x3a/0x50 page last free stack trace: free_pcp_prepare+0x134/0x1e0 free_unref_page+0x18/0x90 khugepaged+0x7b/0xc10 kthread+0xf9/0x130 ret_from_fork+0x3a/0x50 Modules linked in: CPU: 3 PID: 271 Comm: bash Not tainted 5.3.0-rc4-2.g07a1a73-default+ #57 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.12.1-0-ga5cab58-prebuilt.qemu.org 04/01/2014 Call Trace: dump_stack+0x85/0xc0 bad_page.cold+0xba/0xbf rmqueue_pcplist.isra.0+0x6c5/0x6d0 rmqueue+0x2d/0x810 get_page_from_freelist+0x191/0x380 __alloc_pages_nodemask+0x13c/0x2d0 __get_free_pages+0xd/0x30 __pud_alloc+0x2c/0x110 copy_page_range+0x4f9/0x630 dup_mmap+0x362/0x480 dup_mm+0x68/0x110 copy_process+0x19e1/0x1b40 _do_fork+0x73/0x310 __x64_sys_clone+0x75/0x80 do_syscall_64+0x6e/0x1e0 entry_SYSCALL_64_after_hwframe+0x49/0xbe RIP: 0033:0x7f10af854a10 ...

This patch implements CONFIG_DEBUG_VIRTUAL to do additional checks on virt_to_phys and __pa_symbol calls. virt_to_phys used for linear mapping check, and __pa_symbol used for kernel symbol check. In current RISC-V, kernel image maps to linear mapping area. If CONFIG_DEBUG_VIRTUAL is disable, these two functions calculate the offset on the address feded directly without any checks.
