Otherwise, in case the actual output size would be smaller than the expected output size, the subsequent buffer compare test would still succeed, and no error would be reported.

This warning:

  crypto/testmgr.c: In function ‘test_comp’:
  crypto/testmgr.c:829: warning: ‘ret’ may be used uninitialized in this function

triggers because GCC correctly notices that in the ctcount == 0 &&
dtcount != 0 input condition case this function can return an undefined
value, if the second loop fails.

Remove the shadowed 'ret' variable from the second loop that was probably
unintended.

crypto: testmgr - Trigger a panic when self test fails in FIPS mode 2008-12-25T00:01:14+00:00 Neil Horman nhorman@tuxdriver.com 2008-10-12T12:36:51+00:00 d12d6b6d37cad766b390467e770eb0ab81345d78 The FIPS specification requires that should self test for any supported crypto algorithm fail during operation in fips mode, we need to prevent the use of any crypto functionality until such time as the system can be re-initialized. Seems like the best way to handle that would be to panic the system if we were in fips mode and failed a self test. This patch implements that functionality. I've built and run it successfully.

That means users that do not invoke a mode of operations may get an untested cipher. This patch tests all ciphers using the ECB mode so that simple cipher users such as ansi-cprng are also protected.
