[PATCH 0/3] net: use strnstr() for lwip_strnstr()

[Heinrich Schuchardt]

Using strstr() instead of strnstr() creates a security concern.

* Implement missing library function strnstr() and add unit tests.
* Use it for lwIP.

Heinrich Schuchardt (3):
  lib: implement strnstr()
  test: unit tests for strstr() and strnstr()
  net: use strnstr() for lwip_strnstr()
