Subject: kmalloc_node returns unaligned memory
Date: Mon, 13 Mar 2006 15:45:13 +0100 [thread overview]
Message-ID: <20060313144513.GA9542@suse.de> (raw)
kmalloc_node returns unaligned pointers on powerpc, when CONFIG_DEBUG_SLAB
is enabled. This makes iptables very unhappy. It checks the alignment in
net/ipv6/netfilter/ip6_tables.c:check_entry_size_and_hooks().
__alignof__(struct ip6t_entry) returns 8. But returned pointers from
xt_alloc_table_info() are unaligned:
Linux version 2.6.16-rc6-git1-default-iptables-slab (olaf@pomegranate) (gcc version 4.1.0 (SUSE Linux)) #2 Mon Mar 13 15:19:45 CET 2006
...
xt_alloc_table_info(250) modprobe(1687):c0,j4294904016 newinfo/size cfc82498/0x278
xt_alloc_table_info(265) modprobe(1687):c0,j4294904038 entries[0] c449611c
ip_nat_init: can't setup rules.
sys_init_module(1960) modprobe(1687):c0,j4294904071 iptable_nat returned -22
...
Any ideas how to fix that?
