* [libc] Fix memcmp() to return proper valuesMichael J. Bazzinotti2020-07-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Fix memcmp() to return proper standard positive/negative values for unequal comparisons. Current implementation is backwards (i.e. the functions are returning negative when should be positive and vice-versa). Currently most consumers of these functions only check the return value for ==0 or !=0 and so we can safely change the implementation without breaking things. However, there is one call that checks the polarity of this function, and that is prf_sha1() for wireless WPA 4-way handshake. Due to the incorrect memcmp() polarity, the WPA handshake creates an incorrect PTK, and the handshake would fail after step 2. Undoubtedly, the AP noticed the supplicant failed the mic check. This commit fixes that issue. Similar to commit 3946aa9 ("[libc] Fix strcmp()/strncmp() to return proper values").

* [libc] Rewrite strtoul()Michael Brown2015-02-191-0/+48
| | | | | | | | | | The implementation of strtoul() has a partially unknown provenance. Rewrite this code to avoid potential licensing uncertainty. Since we now use -ffunction-sections, there is no need to place strtoull() in a separate file from strtoul(). Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [libc] Prevent strndup() from reading beyond the end of the stringMichael Brown2014-05-181-0/+20
| | | | | | | | | | | | strndup() may be called on a string which is not NUL-terminated. Use strnlen() instead of strlen() to ensure that we do not read beyond the end of such a string. Add self-tests for strndup(), including a test case with an unterminated string. Originally-fixed-by: Marin Hannache <git@mareo.fr> Signed-off-by: Michael Brown <mcb30@ipxe.org>
