Subject: module: don't modify argument of module_kallsyms_lookup_name()
X-Git-Tag: v3.11-rc1~44^2~5
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4f6de4d51f4a3ab06a85e91e708cc89a513ef30c;p=pandora-kernel.git

module: don't modify argument of module_kallsyms_lookup_name()

If we pass a pointer to a const string in the form "module:symbol"
module_kallsyms_lookup_name() will try to split the string at the colon,
i.e., will try to modify r/o data. That will, in fact, fail on a kernel
with enabled CONFIG_DEBUG_RODATA.

Avoid modifying the passed string in module_kallsyms_lookup_name(),
modify find_module_all() instead to pass it the module name length.
