H A D | patch.h | diff 19514910d021c93c7823ec32067e6b7dea224f0f Wed Jan 09 13:43:19 CET 2019 Petr Mladek <pmladek@suse.com> livepatch: Change unsigned long old_addr -> void *old_func in struct klp_func
The address of the to be patched function and new function is stored in struct klp_func as:
void *new_func; unsigned long old_addr;
The different naming scheme and type are derived from the way the addresses are set. @old_addr is assigned at runtime using kallsyms-based search. @new_func is statically initialized, for example:
static struct klp_func funcs[] = { { .old_name = "cmdline_proc_show", .new_func = livepatch_cmdline_proc_show, }, { } };
This patch changes unsigned long old_addr -> void *old_func. It removes some confusion when these address are later used in the code. It is motivated by a followup patch that adds special NOP struct klp_func where we want to assign func->new_func = func->old_addr respectively func->new_func = func->old_func.
This patch does not modify the existing behavior.
