modprobe: call finit_module with MODULE_INIT_COMPRESSED_FILE if module name doesn't end with .ko

2023-03-31T11:15:58+00:00

IOW: if name doesn't end with .ko, assume it's .gz/.xz or similar, and ask kernel to uncompress it. If finit_module(MODULE_INIT_COMPRESSED_FILE) fails, retry with finit_module(0). function old new delta bb_init_module 151 197 +46 Signed-off-by: Denys Vlasenko

cmdline module options can be disabled on "big" modutils

2017-02-01T09:14:05+00:00

Allow module options on command line to be disabled on "big" modutils. Config FEATURE_MODPROBE_SMALL_OPTIONS_ON_CMDLINE is renamed to FEATURE_CMDLINE_MODULE_OPTIONS and no longer depends on !MODPROBE_SMALL (I'm not sure if disabling this is useful on "big" modutils, but at least the macro can serve as a marker and ensure both implementations of same feature have consistent behavior.)

modutils: remove special handling of uClibc

2017-01-04T12:32:09+00:00

Commit 3a45b87ac36f (modutils: support finit_module syscall) introduced macro finit_module. But it is not defined for uClibc. The compilation for busybox fails for MIPS with: With uClibc, we get following build errors: modutils/lib.a(modutils.o): In function `bb_init_module': modutils.c:(.text.bb_init_module+0x94): undefined reference to `finit_module' modutils.c:(.text.bb_init_module+0xa0): undefined reference to `finit_module' We can just use syscall() without any need for the uClibc wrappers. Newer versions of uClibc-ng (>1.0.20) will remove the module syscall wrappers.

modutils: support finit_module syscall

2016-09-15T10:16:33+00:00

On some systems like Chromium OS, loading modules from non-verified filesystems is denied. Only finit_module is allowed because an open fd is passed which can be checked against a verified location. Change the module loading code to first attempt finit_module and if that fails for whatever reason, fall back to the existing logic. On x86_64, this adds ~80 bytes to modutils/modutils.o and ~68 bytes to modutils/modprobe-small.o. Signed-off-by: Mike Frysinger Signed-off-by: Denys Vlasenko

modutils: merge module_entry and module_info to common

2015-11-05T17:54:55+00:00

This merges the in-memory module info structures of modprobe and depmod. This allows sharing hashing by modulename code improving depmod runtime with almost factor of 2x. function old new delta get_or_add_modentry - 17 +17 do_modprobe 590 601 +11 moddb_get_or_create - 10 +10 load_modules_dep 195 205 +10 moddb_get - 7 +7 add_probe 81 78 -3 modprobe_main 721 714 -7 depmod_main 553 543 -10 config_file_action 434 421 -13 helper_get_module 160 144 -16 parse_module 343 320 -23 order_dep_list 105 82 -23 ------------------------------------------------------------------------------ (add/remove: 3/0 grow/shrink: 2/7 up/down: 55/-95) Total: -40 bytes Signed-off-by: Timo Teräs Signed-off-by: Denys Vlasenko
