Hello,
I am doing some investigation regarding an error I am experiencing using my

Hello everyone,
what is the meaning of the number 578 (in this case) in the output of
/proc/slab_allocatos
root@drgos:~# cat /proc/slab_allocators | grep skb
skbuff_head_cache: 578 __alloc_skb+0x38/0x114

Are those bytes, Kbytes, or am I completely wrong ?

would remark that I don't have a fully
understanding of the linux kernel networking stack implementation.
Where should the IPv6 fragmentation be done ?

return ip_finish_output2(skb);
Does not care about it, it just fragments if the MTU does not match.
Is there any options to disable the fragmentation on IPV4 ? I am
misconfiguring something ? Why does the ipip6 has this wrong behavior ?
Thanks in advance,
Pietro.

Hello at all,
I am started with kallsyms in order to debug my kernel deadlock and I don't
understand at all the output, that are some lines of the calltrace:
[ 462.125000] Call Trace:
[ 462.128000] [80019440] show_stack+0x48/0x78
[ 462.132000] [8014e680] showacpu+0xc4/0xf4
[ 462.137000]
Lines like :
ip_finish_output+0x0/0x360
Sounds a bit ambiguous for me, they are just parameters ?
Thanks,

Hello,
I am struggling with the byte order question on a x86_32 arch, I am doing some
modifications on a program which actually works fine on a MIPS arch.
I do a reading from a RAW socket in this way:
/* Configure socket */
if ((fd = socket(AF_INET, SOCK_RAW, IPPROTO_IGMP)) 0)
Hello,
I am using the getifaddrs() function and when I do some computation with the IP
Addresses contained in the ifaddrs struct seems these IP are in network byte

Am I wrong ?
