e5c60f1c28 NULL safety in public places, allows disable logging. 2011-12-08 14:07:13 -02:00
Gustavo Sverzut Barbieri
1bdd951ee2 log: give log function its data instead of kmod_ctx. 
This will be the most common use case for logging, also changed
log_stderr() to log_filep() with data being stderr to test it.

e1a6b30dc4 modname_normalize: fix const and buffer overflow. 
"buf[NAME_MAX] = value" is invalid since it would access the byte
right after the array.

Also fix the const of modname, do not mess with it to avoid mistakes.

f1fb6f8525 kmod_module: Remove const from path 
It's an ugly hack. This is an internal variable, we know we shouldn't
change it everywhere.

1487a64ffa add kmod_module_get_filtered_blacklist() 
This function will filter the given list against the known blacklist,
returning a new list with remaining modules with the reference
incremented.

e005facdb9 Only search path in moddep if it's not already set 
rmmod/insmod should be able to operate directly on files, not relying on
indexes and configuration.

The following test was not working and now it is:

$ # go to a dir != mod->dirname
$ cd /lib/modules/$(uname -r)/kernel
$ # try to insert module giving a relative path
$ insmod drivers/acpi/ac.ko

If a module with the same name already exists, try to reference it if
paths are the same. Otherwise fail.

b7b7ac298f kmod_config: optimize config files handling 
1) Allocate less by not sorting the result with qsort. Instead,
    insert the nodes in the correct order;
 2) Do not maintain the whole path in memory, but rely on openat()

c5b5ea9c7c test: add test to convert name to path 
If we create a kmod_module from a name, the path returned is relative to
the module dirname, as passed during kmod_ctx creation. Note that if
kmod_ctx is created with kmod_new(NULL), the dir used is the one
returned by uname.

f1cd799fb0 kmod_module: return a new list and increase ref of dependencies 
kmod_module_get_dependency is renamed to kmod_module_get_dependencies
since it's returning a list. To match other APIs, now it returns a new
list that user must free with kmod_module_unref_list().

cf91579b8d Inline foreach macro for internal usage 
Avoid calling _next() function because it's an exported function and
linker can not optimize it.

suggestion.

69f9dd4369 no more kmod_loaded and kmod_loaded_module. 
kmod_loaded_get_list() now returns a regular list of kmod_modules, use
kmod_module_get_module(), kmod_module_unref() and
kmod_module_unref_list() to operate on it.

f12ae3c438 kmod_module: extended information gathering. 
provide means to get:
 * refcount
 * initstate
 * holders
 * sections

this can be used to individually query properties from modules,
similar to /proc/modules (kmod_loaded / kmod_loaded_module).
