The various variable-to-sample converters allow to turn a variable to a sample of type string, sint or binary, but both the string one used by strcmp() and the binary one used by secure_memcmp() are missing a pointer check on the ability to the cast, making them crash if a variable of type addr is used with strcmp(), or if an addr or bool is used with secure_memcmp(). Let's rely on the new sample_conv_var2smp() function to run the proper checks. This will need to be backported to all supported version. It relies on previous commits: CLEANUP: server: always include the storage for SSL settings CLEANUP: sample: rename sample_conv_var2smp() to *_sint CLEANUP: sample: uninline sample_conv_var2smp_str() MINOR: sample: provide a generic var-to-sample conversion function For backports it's probably easier to check the sample_casts[] pointer before calling it in sample_conv_strcmp() and sample_conv_secure_memcmp().
