For the working insmod under 2.4.20-8, it has NULL pointer for buffer amd /* 8 entries */ for module, like following: query_module(NULL, 0, NULL, 0) = 0 query_module(NULL, QM_MODULES, { /* 8 entries */ }, 8) = 0 query_module("autofs", QM_INFO, {address=0xd08d8000, size=13684, flags=MOD_RUNNING|MOD_AUTOCLEAN, usecount=0}, 16) = 0 brk(0) = 0x807d000 brk(0x807e000) = 0x807e000 query_module("autofs", QM_SYMBOLS, { /* 21 entries */ }, 21) = 0 query_module("e100", QM_INFO, {address=0xd08c5000, size=62340, flags=MOD_RUNNING|MOD_VISITED|MOD_USED_ONCE, usecount=0}, 16) = 0 query_module("e100", QM_SYMBOLS, 0x807d178, 1024, 1919) = -1 ENOSPC (No space left on device) query_module("e100", QM_SYMBOLS, { /* 67 entries */ }, 67) = 0 However, on same system but booted with 2.5.72 bzImage, it has the following, query_module(NULL, 0, 0, 0, 134725736) = -1 ENOSYS (Function not implemented) query_module(NULL, QM_MODULES, 0x807cd38, 256, 1108208563) = -1 ENOSYS (Function not implemented) write(2, "insmod: ", 8insmod: ) = 8 write(2, "QM_MODULES: Function not impleme"..., 37QM_MODULES: Function not implemented) = 37 write(2, "\n", 1) = 1 flock(3, LOCK_UN) = 0 close(3) = 0 chdir("/var/log/ksymoops") = -1 ENOENT (No such file or directory) exit_group(1) = ?
