Inca o eroare ( de linking ... ??? ) la care ma dau cu capul de peretzi ...
compilez modulele pentru kernel 2.4.28 ... patch cu ipt_ACCOUNT ... si
imi da minunatzie :

Buuuuun .. ma uit in /usr/src/linux/net/ipv4/netfilter/ipt_ACCOUNT.c :

Ce naiba vrea ? Ma uit sa vad daca am heeaderul inclus, si in linia 29 am :
#include <linux/netfilter_ipv4/ipt_ACCOUNT.h>
daca ma uit in ipt_ACCOUNT.h ... totul e ok ! :
92: struct ipt_acc_mask_16 {
93: struct ipt_acc_mask_24 *mask_24[256];
94: };
Care e faza ? Am eu senzatia ca gccul nu face linkarea corecta cu
/usr/src/linux/include ?
De ce mai sus cand face :
struct ipt_acc_mask_8 *src_8 =
(struct ipt_acc_mask_8 *)ipt_acc_tables[table_nr].data;
struct ipt_acc_mask_8 *network_8 =
(struct ipt_acc_mask_8 *)ipt_acc_handles[handle].data;
u_int32_t a;
nu imi da eroare ? Sunt eu nebun ? Sa ma apuc de altceva ?
