Nayna Jain d696e7d91e programs/ssl: Fix incorrect EOF check in ssl_context_info.c
In `read_next_b64_code()`, the result of fgetc() is stored into a char,
but later compared against EOF, which is generally -1.  On platforms
where char is unsigned, this generates a compiler warning/error that the
comparison will never be true (causing a build failure).  The value will
never match, with the function ultimately bailing with a "Too many bad
symbols are detected" error.

On platforms with signed char, EOF is detected, but a file containing a
0xFF character will causes a premature end of file exit of the loop.

Fix this by changing the result to an int.

Fixes #3794.

The calculation of the expected key size when not using the test_size_function
was not correct. The function has now been updated to handle all cases
properly to ensure the expected key size is correct for key pairs, public
keys, and symmetric keys.

Fredrik Strupe 5e940c6068 Fix additional data length field check for CCM
The CCM specification (NIST SP 800-38C) mandates that the formatting of
the additional data length l(a) changes when it is greater _or equal_ to
2^16 - 2^8 (>= 0xFF00). Since such lengths are not supported in mbed TLS,
the operation should fail in such cases.

This commit fixes an off-by-one error which allowed encryption/decryption
to be executed when l(a) was equal to 0xFF00, resulting in an
incorrect/non-standard length format being used.

Fixes #3719.

Gilles Peskine c6468ee247 Revert "Use glibc's getrandom() instead of syscall when glibc > 2.25."
This reverts commit 9c46a60e6c.

When the library is dynamically linked against Glibc (as is usually
the case with Glibc), it now requires a recent Glibc at runtime if it
was compiled with a recent Glibc. This is a loss of functionality for
no demonstrated benefit.

Gilles Peskine 2acbed387d psa_generate_key: remove the bit-size sanity check
In psa_generate_key_internal() for ECC keys, remove the check that the
bit-size according to Mbed TLS is equal to the requested bit-size.
This check was necessary back when the PSA API encoded curves and key
sizes independently, in order to reject combinations such as SECP256R1
with a 512-bit size. Since the curve encoding changed to specifying a
curve family and a size separately, the Mbed TLS curve id (grp_id) and
the curve data (curve_info) are now determined from the size, and
checking that (curve_info->bit_size == bits) is now only a redundant
sanity check.

This check is actually buggy, because PSA Crypto and Mbed TLS don't
have exactly the same notion of key size. PSA thinks Curve25519 is
255-bit and secp224k1 is 225-bit, but Mbed TLS thinks they're 256-bit
and 224-bit respectively. Removing the check allows key generation to
work for these curves.

mbedtls_ecp_curve_list() now lists Curve25519 and Curve448 under the names
"x25519" and "x448". These curves support ECDH but not ECDSA.

This was meant ever since the introduction of mbedtls_ecdsa_can_do()
in 0082f9df6f, but
2c69d10bac had removed the claim
that Montgomery curves support ECDH except through Everest.

Use glibc's getrandom when glibc > 2.25
2020-09-30 13:55:04 +02:00
Fredrik Strupe f90e3019dd Use PSA_ERROR_INVALID_ARGUMENT for invalid cipher input sizes
... as opposed to PSA_ERROR_BAD_STATE.

The spec on psa_cipher_finish() states that PSA_ERROR_INVALID_ARGUMENT
should be returned when:

"The total input size passed to this operation is not valid for this
particular algorithm. For example, the algorithm is a based on block
cipher and requires a whole number of blocks, but the total input size
is not a multiple of the block size."

Currently, there is a distinction between encryption and decryption
on whether INVALID_ARGUMENT or BAD_STATE is returned, but this is not
a part of the spec.

This fix ensures that PSA_ERROR_INVALID_ARGUMENT is returned
consistently on invalid cipher input sizes.
