openssl-1_1/openssl-1.1.1-evp-kdf.patch
Pedro Monreal Gonzalez 32ced036f1 Accepting request 786956 from home:vitezslav_cizek:branches:security:tls 
- Update to 1.1.1e
  * Properly detect EOF while reading in libssl. Previously if we hit an EOF
    while reading in libssl then we would report an error back to the
    application (SSL_ERROR_SYSCALL) but errno would be 0. We now add
    an error to the stack (which means we instead return SSL_ERROR_SSL) and
    therefore give a hint as to what went wrong.
  * Check that ed25519 and ed448 are allowed by the security level. Previously
    signature algorithms not using an MD were not being checked that they were
    allowed by the security level.
  * Fixed SSL_get_servername() behaviour. The behaviour of SSL_get_servername()
    was not quite right. The behaviour was not consistent between resumption
    and normal handshakes, and also not quite consistent with historical
    behaviour. The behaviour in various scenarios has been clarified and
    it has been updated to make it match historical behaviour as closely as
    possible.
  * Corrected the documentation of the return values from the EVP_DigestSign*
    set of functions.  The documentation mentioned negative values for some
    errors, but this was never the case, so the mention of negative values
    was removed.
  * Added a new method to gather entropy on VMS, based on SYS$GET_ENTROPY.
    The presence of this system service is determined at run-time.
  * Added newline escaping functionality to a filename when using openssl dgst.
    This output format is to replicate the output format found in the '*sum'
    checksum programs. This aims to preserve backward compatibility.
  * Print all values for a PKCS#12 attribute with 'openssl pkcs12', not just
    the first value.
- Update bunch of patches as the internal crypto headers got reorganized
- drop openssl-1_1-CVE-2019-1551.patch (upstream)

- openssl dgst: default to SHA256 only when called without a digest,

+After creating a C<EVP_KDF_CTX> for the required algorithm using
+EVP_KDF_CTX_new_id(), inputs to the algorithm are supplied using calls to
+EVP_KDF_ctrl(), EVP_KDF_vctrl() or EVP_KDF_ctrl_str() before calling
+EVP_KDF_derive() to derive the key.
+
+=head2 Types
+
+B<EVP_KDF_CTX> is a context type that holds the algorithm inputs.
+
+=head2 Context manipulation functions
+
+EVP_KDF_CTX_new_id() creates a KDF context for the algorithm identified by the
+specified NID.
+
+EVP_KDF_CTX_free() frees up the context C<ctx>. If C<ctx> is C<NULL>, nothing
+is done.
+
+=head2 Computing functions
+
+EVP_KDF_reset() resets the context to the default state as if the context
+had just been created.
+
+EVP_KDF_ctrl() is used to provide inputs to the KDF algorithm prior to
+EVP_KDF_derive() being called. The inputs that may be provided will vary
+depending on the KDF algorithm or its implementation. This functions takes
+variable arguments, the exact expected arguments depend on C<cmd>.
+See L</CONTROLS> below for a description of standard controls.
+
+EVP_KDF_vctrl() is the variant of EVP_KDF_ctrl() that takes a C<va_list>
+argument instead of variadic arguments.
+
+EVP_KDF_ctrl_str() allows an application to send an algorithm specific control
+operation to a context C<ctx> in string form. This is intended to be used for
+options specified on the command line or in text files.
+
+EVP_KDF_size() returns the output size if the algorithm produces a fixed amount
+of output and C<SIZE_MAX> otherwise. If an error occurs then 0 is returned.
+For some algorithms an error may result if input parameters necessary to
+calculate a fixed output size have not yet been supplied.
+
+EVP_KDF_derive() derives C<keylen> bytes of key material and places it in the
+C<key> buffer. If the algorithm produces a fixed amount of output then an
+error will occur unless the C<keylen> parameter is equal to that output size,
+as returned by EVP_KDF_size().
+
+=head1 CONTROLS
+
+The standard controls are:
+
+=over 4
+
+=item B<EVP_KDF_CTRL_SET_PASS>
+
+This control expects two arguments: C<unsigned char *pass>, C<size_t passlen>
+
+Some KDF implementations require a password. For those KDF implementations
+that support it, this control sets the password.
+
+EVP_KDF_ctrl_str() takes two type strings for this control:
+
+=over 4
+
+=item "pass"
+
+The value string is used as is.
+
+=item "hexpass"
+
+The value string is expected to be a hexadecimal number, which will be

+
+=item B<EVP_KDF_CTRL_SET_SALT>
+
+This control expects two arguments: C<unsigned char *salt>, C<size_t saltlen>
+
+Some KDF implementations can take a salt. For those KDF implementations that
+support it, this control sets the salt.
+
+The default value, if any, is implementation dependent.

+=item B<EVP_KDF_CTRL_SET_ITER>
+
+This control expects one argument: C<int iter>
+

+The default value, if any, is implementation dependent.
+
+EVP_KDF_ctrl_str() type string: "iter"
+
+The value string is expected to be a decimal number.
+
+=item B<EVP_KDF_CTRL_SET_MD>
+
+This control expects one argument: C<EVP_MD *md>
+
+For MAC implementations that use a message digest as an underlying computation
+algorithm, this control set what the digest algorithm should be.
+
+EVP_KDF_ctrl_str() type string: "md"
+
+The value string is expected to be the name of a digest.
+
+=item B<EVP_KDF_CTRL_SET_KEY>
+
+This control expects two arguments: C<unsigned char *key>, C<size_t keylen>
+
+Some KDF implementations require a key. For those KDF implementations that
+support it, this control sets the key.
+
+EVP_KDF_ctrl_str() takes two type strings for this control:

+
+=item "key"
+
+The value string is used as is.

+
+=back
+
+=item B<EVP_KDF_CTRL_SET_MAXMEM_BYTES>
+
+This control expects one argument: C<uint64_t maxmem_bytes>
+
+Memory-hard password-based KDF algorithms, such as scrypt, use an amount of
+memory that depends on the load factors provided as input. For those KDF
+implementations that support it, this control sets an upper limit on the amount
+of memory that may be consumed while performing a key derivation. If this
+memory usage limit is exceeded because the load factors are chosen too high,
+the key derivation will fail.
+
+The default value is implementation dependent.
+
+EVP_KDF_ctrl_str() type string: "maxmem_bytes"
+
+The value string is expected to be a decimal number.
+
+=back
+
+=head1 RETURN VALUES
+
+EVP_KDF_CTX_new_id() returns either the newly allocated C<EVP_KDF_CTX>
+structure or C<NULL> if an error occurred.
+
+EVP_KDF_CTX_free() and EVP_KDF_reset() do not return a value.
+
+EVP_KDF_size() returns the output size. C<SIZE_MAX> is returned to indicate
+that the algorithm produces a variable amount of output; 0 to indicate failure.
+
+The remaining functions return 1 for success and 0 or a negative value for
+failure. In particular, a return value of -2 indicates the operation is not
+supported by the KDF algorithm.

+=head1 NAME
+
+EVP_KDF_HKDF - The HKDF EVP_KDF implementation
+
+=head1 DESCRIPTION
+
+Support for computing the B<HKDF> KDF through the B<EVP_KDF> API.
+
+The EVP_KDF_HKDF algorithm implements the HKDF key derivation function.
+HKDF follows the "extract-then-expand" paradigm, where the KDF logically
+consists of two modules. The first stage takes the input keying material
+and "extracts" from it a fixed-length pseudorandom key K. The second stage
+"expands" the key K into several additional pseudorandom keys (the output
+of the KDF).
+
+=head2 Numeric identity
+
+B<EVP_KDF_HKDF> is the numeric identity for this implementation; it
+can be used with the EVP_KDF_CTX_new_id() function.
+
+=head2 Supported controls
+
+The supported controls are:
+
+=over 4
+
+=item B<EVP_KDF_CTRL_SET_SALT>
+
+=item B<EVP_KDF_CTRL_SET_MD>
+
+=item B<EVP_KDF_CTRL_SET_KEY>
+
+These controls work as described in L<EVP_KDF_CTX(3)/CONTROLS>.
+
+=item B<EVP_KDF_CTRL_RESET_HKDF_INFO>
+
+This control does not expect any arguments.
+
+Resets the context info buffer to zero length.
+
+=item B<EVP_KDF_CTRL_ADD_HKDF_INFO>
+
+This control expects two arguments: C<unsigned char *info>, C<size_t infolen>
+
+Sets the info value to the first B<infolen> bytes of the buffer B<info>. If a
+value is already set, the contents of the buffer are appended to the existing
+value.
+
+The total length of the context info buffer cannot exceed 1024 bytes;
+this should be more than enough for any normal use of HKDF.
+
+EVP_KDF_ctrl_str() takes two type strings for this control:
+
+=over 4
+
+=item "info"
+
+The value string is used as is.
+
+=item "hexinfo"
+
+The value string is expected to be a hexadecimal number, which will be
+decoded before being passed on as the control value.
+
+=back
+
+=item B<EVP_KDF_CTRL_SET_HKDF_MODE>
+
+This control expects one argument: C<int mode>
+
+Sets the mode for the HKDF operation. There are three modes that are currently
+defined:
+
+=over 4
+
+=item EVP_KDF_HKDF_MODE_EXTRACT_AND_EXPAND
+
+This is the default mode. Calling L<EVP_KDF_derive(3)> on an EVP_KDF_CTX set
+up for HKDF will perform an extract followed by an expand operation in one go.
+The derived key returned will be the result after the expand operation. The
+intermediate fixed-length pseudorandom key K is not returned.
+
+In this mode the digest, key, salt and info values must be set before a key is
+derived otherwise an error will occur.
+
+=item EVP_KDF_HKDF_MODE_EXTRACT_ONLY
+
+In this mode calling L<EVP_KDF_derive(3)> will just perform the extract
+operation. The value returned will be the intermediate fixed-length pseudorandom
+key K. The C<keylen> parameter must match the size of K, which can be looked
+up by calling EVP_KDF_size() after setting the mode and digest.
+
+The digest, key and salt values must be set before a key is derived otherwise
+an error will occur.
+
+=item EVP_KDF_HKDF_MODE_EXPAND_ONLY
+
+In this mode calling L<EVP_KDF_derive(3)> will just perform the expand
+operation. The input key should be set to the intermediate fixed-length
+pseudorandom key K returned from a previous extract operation.
+
+The digest, key and info values must be set before a key is derived otherwise
+an error will occur.
+
+=back
+
+EVP_KDF_ctrl_str() type string: "mode"
+
+The value string is expected to be one of: "EXTRACT_AND_EXPAND", "EXTRACT_ONLY"
+or "EXPAND_ONLY".
+
+=back
+
+=head1 NOTES
+
+A context for HKDF can be obtained by calling:
+
+ EVP_KDF_CTX *kctx = EVP_KDF_CTX_new_id(EVP_KDF_HKDF);
+
+The output length of an HKDF expand operation is specified via the C<keylen>
+parameter to the L<EVP_KDF_derive(3)> function. When using
+EVP_KDF_HKDF_MODE_EXTRACT_ONLY the C<keylen> parameter must equal the size of
+the intermediate fixed-length pseudorandom key otherwise an error will occur.
+For that mode, the fixed output size can be looked up by calling EVP_KDF_size()
+after setting the mode and digest on the C<EVP_KDF_CTX>.
+
+=head1 EXAMPLE
+
+This example derives 10 bytes using SHA-256 with the secret key "secret",
+salt value "salt" and info value "label":
+
+ EVP_KDF_CTX *kctx;
+ unsigned char out[10];
+
+ kctx = EVP_KDF_CTX_new_id(EVP_KDF_HKDF);

+These controls work as described in L<EVP_KDF_CTX(3)/CONTROLS>.
+
+B<iter> is the iteration count and its value should be greater than or equal to

+
+=head1 NOTES
+
+A typical application of this algorithm is to derive keying material for an
+encryption algorithm from a password in the B<pass>, a salt in B<salt>,
+and an iteration count.
+
+Increasing the B<iter> parameter slows down the algorithm which makes it
+harder for an attacker to perform a brute force attack using a large number
+of candidate passwords.
+
+No assumption is made regarding the given password; it is simply treated as a
+byte sequence.

+=head1 NAME
+
+EVP_KDF_SCRYPT - The scrypt EVP_KDF implementation
+
+=head1 DESCRIPTION
+
+Support for computing the B<scrypt> password-based KDF through the B<EVP_KDF>
+API.
+
+The EVP_KDF_SCRYPT algorithm implements the scrypt password-based key
+derivation function, as described in RFC 7914. It is memory-hard in the sense
+that it deliberately requires a significant amount of RAM for efficient
+computation. The intention of this is to render brute forcing of passwords on
+systems that lack large amounts of main memory (such as GPUs or ASICs)
+computationally infeasible.
+
+scrypt provides three work factors that can be customized: N, r and p. N, which
+has to be a positive power of two, is the general work factor and scales CPU
+time in an approximately linear fashion. r is the block size of the internally
+used hash function and p is the parallelization factor. Both r and p need to be
+greater than zero. The amount of RAM that scrypt requires for its computation
+is roughly (128 * N * r * p) bytes.
+
+In the original paper of Colin Percival ("Stronger Key Derivation via
+Sequential Memory-Hard Functions", 2009), the suggested values that give a
+computation time of less than 5 seconds on a 2.5 GHz Intel Core 2 Duo are N =
+2^20 = 1048576, r = 8, p = 1. Consequently, the required amount of memory for
+this computation is roughly 1 GiB. On a more recent CPU (Intel i7-5930K at 3.5
+GHz), this computation takes about 3 seconds. When N, r or p are not specified,
+they default to 1048576, 8, and 1, respectively. The maximum amount of RAM that
+may be used by scrypt defaults to 1025 MiB.

+=item B<EVP_KDF_CTRL_RESET_TLS_SEED>
+
+This control does not expect any arguments.
+
+Resets the context seed buffer to zero length.
+
+=item B<EVP_KDF_CTRL_ADD_TLS_SEED>
+
+This control expects two arguments: C<unsigned char *seed>, C<size_t seedlen>
+
+Sets the seed to B<seedlen> bytes of B<seed>. If a seed is already set it is
+appended to the existing value.
+
+The total length of the context seed buffer cannot exceed 1024 bytes;
+this should be more than enough for any normal use of the TLS PRF.
+
+EVP_KDF_ctrl_str() takes two type strings for this control:

+
+=head1 NOTES
+
+A context for the TLS PRF can be obtained by calling:
+
+ EVP_KDF_CTX *kctx = EVP_KDF_CTX_new_id(EVP_KDF_TLS1_PRF, NULL);
+
+The digest, secret value and seed must be set before a key is derived otherwise
+an error will occur.
+
+The output length of the PRF is specified by the C<keylen> parameter to the
+EVP_KDF_derive() function.
+
+=head1 EXAMPLE
+
+This example derives 10 bytes using SHA-256 with the secret key "secret"
+and seed value "seed":
+
+ EVP_KDF_CTX *kctx;
+ unsigned char out[10];
+
+ kctx = EVP_KDF_CTX_new_id(EVP_KDF_TLS1_PRF);
+ if (EVP_KDF_ctrl(kctx, EVP_KDF_CTRL_SET_MD, EVP_sha256()) <= 0) {
+ error("EVP_KDF_CTRL_SET_MD");
+ }
+ if (EVP_KDF_ctrl(kctx, EVP_KDF_CTRL_SET_TLS_SECRET,
+ "secret", (size_t)6) <= 0) {
+ error("EVP_KDF_CTRL_SET_TLS_SECRET");
