      module: remove module_text_address() · a6e6abd5
      Rusty Russell authored
      Impact: Replace and remove risky (non-EXPORTed) API
      
      module_text_address() returns a pointer to the module, which given locking
      improvements in module.c, is useless except to test for NULL:
      
      1) If the module can't go away, use __module_text_address.
      2) Otherwise, just use is_module_text_address().

      module: __module_address · e610499e
      Rusty Russell authored
      Impact: New API, cleanup
      
      ksplice wants to know the bounds of a module, not just the module text.
      
      It makes sense to have __module_address.  We then implement
      is_module_address and __module_text_address in terms of this (and
      change is_module_text_address() to bool while we're at it).
      
      Also, add proper kerneldoc for them all.

      module: Make find_symbol return a struct kernel_symbol · 414fd31b
      Tim Abbott authored
      Impact: Cleanup, internal API change
      
      Ksplice needs access to the kernel_symbol structure in order to support
      modifications to the exported symbol table.

      kernel/module.c: fix an unused goto label · b10153fe
      Américo Wang authored
      Impact: cleanup
      
      Label 'free_init' is only used when defined(CONFIG_MODULE_UNLOAD) &&
      defined(CONFIG_SMP), so move it inside to shut up gcc.

      param: fix charp parameters set via sysfs · e180a6b7
      Rusty Russell authored
      Impact: fix crash on reading from /sys/module/.../ieee80211_default_rc_algo
      
      The module_param type "charp" simply sets a char * pointer in the
      module to the parameter in the commandline string: this is why we keep
      the (mangled) module command line around.  But when set via sysfs (as
      about 11 charp parameters can be) this memory is freed on the way
      out of the write().  Future reads hit random mem.
      
      So we kstrdup instead: we have to check we're not in early commandline
      parsing, and we have to note when we've used it so we can reliably
      kfree the parameter when it's next overwritten, and also on module
      unload.
      
      (Thanks to Randy Dunlap for CONFIG_SYSFS=n fixes)
