2017-02-05Reorder modutils config options & fix yet more dependencyKang-Che Sung
- modprobe can indirectly benefit from FEATURE_2_4_MODULES and FEATURE_INSMOD_TRY_MAP options. - The position of config FEATURE_INSMOD_TRY_MMAP prevented some other config options from indenting under FEATURE_2_4_MODULES. Reorder to fix this. - FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED is now moved to Config.src under "Common options" section. (I wished to edit this config so that it also work with "big" modutils, but it's not done at the moment. Sorry.)

2017-02-05modutils: fix config options dependency (2)Kang-Che Sung
- The modprobe-small implementation of rmmod no longer chdir's to "/lib/modules/`uname -r`" as it was not necessary for rmmod's operation. (And it no longer need to die if such modules directory doesn't exist.) - Configs DEFAULT_MODULES_DIR and DEFAULT_DEPMOD_FILE no longer depend on MODPROBE_SMALL as the latter may not enable depmod or modprobe that requires these configs. - Clarify DEFAULT_DEPMOD_FILE's description regarding the ".bb" name suffix.

2017-02-01cmdline module options can be disabled on "big" modutilsKang-Che Sung
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.)

module.aliases and module.symbols files have no use in modprobe-small implementation. So FEATURE_MODUTILS_ALIAS and FEATURE_MODUTILS_SYMBOLS will depend on !MODPROBE_SMALL. The try_to_mmap_module() function is not called in modprobe-small.c, so I will let FEATURE_INSMOD_TRY_MMAP depend on !MODPROBE_SMALL for now.

2017-01-09modprobe-small: optimizations for single applet buildExplorer09
(I'm requesting for a review first because I fear such an aggressive change could lead to bugs. While I observe the sizes have reduced, I haven't test the functionality of each applet after that. So please test before merging.) Aggressively cut off unneeded code when the relevant applets are not built. Correct dependencies of FEATURE_MODPROBE_SMALL_OPTIONS_ON_CMDLINE and FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED. Don't bother with the '-r' option check if only rmmod is built (assume true then), or when neither rmmod or mobprobe is built (assume false then).

2017-01-04modutils: remove special handling of uClibcWaldemar Brodkorb
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.

2016-09-15modutils: support finit_module syscallMike Frysinger
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.

usecase: two sd cards are being mounted in parallel at same time on dual core. example modules which are getting loaded is nls_cp437. While one module is being loaded , it makes state in /proc/modules as 'coming' and then starts doing its module init function (in our case - registering nls). meanwhile on other core, if modprobe returns that is has already been loaded, then it will continue and search for the nls list which is not yet finished from first module init.
