Re: [B.A.T.M.A.N.] [PATCH 4/6] batctl: Return success only with valid line_ptr in read_file

On Saturday 24 May 2014 14:16:42 Sven Eckelmann wrote:

The read_file function is rather complex and cluttered with different functionality. One of it is to provide a line_ptr of a single line to the caller. The caller trusts the return code for a SUCCESS of this function and tries to access the line_ptr. But a failed getline may lead to an NULL-line_ptr. The caller tries to dereference this NULL pointer and causes an segfault.
