Declare get_kernel_config(), load_module_symbols_helper()
for crash outside extension users.
CRASH_MODULE_PATH valiable can apply to search non-standard module path
from load_module_symbols_helper() and "mod" command.
- get_kernel_config("config name", &val)
Return one of target kernel configurations.
If val == NULL, return value is poinited whether config is valid or not.
IKCONFIG_N: kernel config is not set (not valid).
IKCONFIG_Y: kernel config is set y (valid).
IKCONFIG_M: kernel config is set m (valid).
IKCONFIG_STR: kernel config is values or strings, etc (valid).
"help -k" can display ikconfig setup state,
number of valid ikconfig entries, function calls.
Notes:
1. How to activate get_kernel_config().
read_in_kernel_config(IKCFG_SETUP)
-> get_kernel_config() become active.
read_in_kernel_config(IKCFG_FREE)
-> get_kernel_config() become iniactive.
2. This function require CONFIG_IKCONFIG=y. Otherwise user is warned.
Functional change from previous one.
"config name" can be allowed both with or without CONFIG_ prefix strings.
[ Dave's recommendation ]
- load_module_symbols_helper("module name")
Load specified kernel module symbols with argument.
This is simplified usage from original load_module_symbols().
Add "CRASH_MODULE_PATH" valiable which can use to resolve
non-standard module path.
Functional change from previous one.
"CRASH_MODULE_PATH" could be used by the "mod -s" command as well.
[ Dave's recommendation ]
Example usage:
< in .crashrc >
mod -s ext3
mod -s jbd
:
:
export CRASH_MODULE_PATH="your module's root directory"
/usr/sbin/crash
Even if target kernel is changed,
crash will load appropriate ext3 or jbd modules by this valiable.
