As requested by Ben, I'm forward-porting the changes from no_gmt_unix_time (pull request #23) to 1.0.2 and master. This branch merges cleanly to 1.0.2 and 1.0.2-aead, and its two commits cherry-pick cleanly to master. They include another fix that was not in the original branch; I'm opening a second pull request for that one.

@nmathewson
Do not include a timestamp in the Client/ServerHello Random field.
d757097 
Instead, send random bytes, unless SSL_SEND_{CLIENT,SERVER}RANDOM_MODE
is set.

This is a forward-port of commits:
  4af7930
  f4c93b4
  3da721d
  2583270

While the gmt_unix_time record was added in an ostensible attempt to
mitigate the dangers of a bad RNG, its presence leaks the host's view
of the current time in the clear.  This minor leak can help
fingerprint TLS instances across networks and protocols... and what's
worse, it's doubtful thet the gmt_unix_time record does any good at
all for its intended purpose, since:

    * It's quite possible to open two TLS connections in one second.

    * If the PRNG output is prone to repeat itself, ephemeral
      handshakes (and who knows what else besides) are broken.

If we lowercase them, the occasional registered mixed case ID will not

This can be reproduced with my error injection patch.

The test vector has been validated on the 1.1.1 branch
but the issue is of course identical in all branches.

    Fix documentation of BIO_FLAGS_BASE64_NO_NL

    Commit 8bfb750 updated
    `BIO_f_base64(3)` to improve the documentation of the
    `BIO_FLAGS_BASE64_NO_NL` flag.  In particular, the updated text
    states that when this flag is used, all newlines in the input are
    ignored.  This is incorrect, as the following program proves:

    ```c

    unsigned char *in_buf =
        "IlRoZSBxdWljayBicm93biBmb3gganVt\ncHMgb3ZlciBhIGxhenkgZG9nLiI=\n";

    int main(int argc, char **argv) {
        BIO *b64 = BIO_new(BIO_f_base64());
        if (b64 == NULL) return 1;
        BIO_set_flags(b64, BIO_get_flags(b64) | BIO_FLAGS_BASE64_NO_NL);
        int in_len = strlen(in_buf);
        BIO *in = BIO_new_mem_buf(in_buf, in_len);
        if (in == NULL) return 2;
        in = BIO_push(b64, in);
        unsigned char *out_buf = calloc(in_len, sizeof(unsigned char));
        if (out_buf == NULL) return 3;
        size_t out_len;
        int r = BIO_read_ex(in, out_buf, in_len, &out_len);
        printf("rv = %d\n", r);
        printf("decoded = %s\n", out_buf);
        return 0;
    }
    ```

    Update the text of `BIO_f_base64(3)` to clarify that when the flag
    is set, the data must be all on one line (with or without a trailing
    newline character).

Author: Tomas Mraz <tomas@openssl.org>
Date:   Thu Jun 9 12:34:55 2022 +0200

    Always end BN_mod_exp_mont_consttime with normal Montgomery reduction.

    This partially fixes a bug where, on x86_64, BN_mod_exp_mont_consttime
    would sometimes return m, the modulus, when it should have returned
    zero. Thanks to Guido Vranken for reporting it. It is only a partial fix
    because the same bug also exists in the "rsaz" codepath.

    The bug only affects zero outputs (with non-zero inputs), so we believe
    it has no security impact on our cryptographic functions.

    The fx is to delete lowercase bn_from_montgomery altogether, and have the
    mont5 path use the same BN_from_montgomery ending as the non-mont5 path.
    This only impacts the final step of the whole exponentiation and has no
    measurable perf impact.

    Fix a crash in ssl_security_cert_chain

    Prior to the crash there is an out of memory error
    in X509_verify_cert which makes the chain NULL or
    empty.  The error is ignored by ssl_add_cert_chain,
    and ssl_security_cert_chain crashes due to the
    unchecked null pointer.

    This is reproducible with my error injection patch.

    The test vector has been validated on the 1.1.1 branch
    but the issue is of course identical in all branches.

    Fix a crash in asn1_item_embed_new

    This happens usually if an template object is created
    and there is an out of memory error before the ASN1_OP_NEW_POST
    method is called, but asn1_item_embed_free calls now the
    ASN1_OP_FREE_POST which may crash because the object is not
    properly initialized.  Apparently that is only an issue with
    the ASN1_OP_FREE_POST handling of crypot/x509/x_crl.c, which
    ought to be tolerant to incomplete initialized objects.

    The error can be reproduced with the reproducible error injection patch:

    Fix leakage when the cacheline is 32-bytes in CBC_MAC_ROTATE_IN_PLACE

    rotated_mac is a 64-byte aligned buffer of size 64 and rotate_offset is secret.
    Consider a weaker leakage model(CL) where only cacheline base address is leaked,
    i.e address/32 for 32-byte cacheline(CL32).

    Previous code used to perform two loads
        1. rotated_mac[rotate_offset ^ 32] and
        2. rotated_mac[rotate_offset++]
    which would leak 2q + 1, 2q for 0 <= rotate_offset < 32
    and 2q, 2q + 1 for 32 <= rotate_offset < 64

    The proposed fix performs load operations which will always leak 2q, 2q + 1 and
    selects the appropriate value in constant-time.

    Fix AES OCB encrypt/decrypt for x86 AES-NI

    aesni_ocb_encrypt and aesni_ocb_decrypt operate by having a fast-path
    that performs operations on 6 16-byte blocks concurrently (the
    "grandloop") and then proceeds to handle the "short" tail (which can
    be anywhere from 0 to 5 blocks) that remain.

    As part of initialization, the assembly initializes $len to the true
    length, less 96 bytes and converts it to a pointer so that the $inp
    can be compared to it. Each iteration of "grandloop" checks to see if
    there's a full 96-byte chunk to process, and if so, continues. Once
    this has been exhausted, it falls through to "short", which handles
    the remaining zero to five blocks.

    Unfortunately, the jump at the end of "grandloop" had a fencepost
    error, doing a `jb` ("jump below") rather than `jbe` (jump below or
    equal). This should be `jbe`, as $inp is pointing to the *end* of the
    chunk currently being handled. If $inp == $len, that means that
    there's a whole 96-byte chunk waiting to be handled. If $inp > $len,
    then there's 5 or fewer 16-byte blocks left to be handled, and the
    fall-through is intended.

    The net effect of `jb` instead of `jbe` is that the last 16-byte block
    of the last 96-byte chunk was completely omitted. The contents of
    `out` in this position were never written to. Additionally, since
    those bytes were never processed, the authentication tag generated is
    also incorrect.

    The same fencepost error, and identical logic, exists in both
    aesni_ocb_encrypt and aesni_ocb_decrypt.

    This addresses CVE-2022-2097.

    Fix bn_gcd code to check return value when calling BN_one()

    BN_one() uses the expand function which calls malloc which may fail.
    All other places that reference BN_one() check the return value.

    The issue is triggered by a memory allocation failure.

    Fix range_should_be_prefix() to actually return the correct result

    range_should_be_prefix() was misidentifying whether an IP address range
    should in fact be represented as a prefix. This was due to a bug introduced
    in commit 42d7d7d which made this incorrect change:

    -    OPENSSL_assert(memcmp(min, max, length) <= 0);
    +    if (memcmp(min, max, length) <= 0)
    +        return -1;

    This error leads to incorrect DER being encoded/accepted.

    Fix documentation of BIO_FLAGS_BASE64_NO_NL

    Commit 8bfb750 updated
    `BIO_f_base64(3)` to improve the documentation of the
    `BIO_FLAGS_BASE64_NO_NL` flag.  In particular, the updated text
    states that when this flag is used, all newlines in the input are
    ignored.  This is incorrect, as the following program proves:

    ```c

    unsigned char *in_buf =
        "IlRoZSBxdWljayBicm93biBmb3gganVt\ncHMgb3ZlciBhIGxhenkgZG9nLiI=\n";

    int main(int argc, char **argv) {
        BIO *b64 = BIO_new(BIO_f_base64());
        if (b64 == NULL) return 1;
        BIO_set_flags(b64, BIO_get_flags(b64) | BIO_FLAGS_BASE64_NO_NL);
        int in_len = strlen(in_buf);
        BIO *in = BIO_new_mem_buf(in_buf, in_len);
        if (in == NULL) return 2;
        in = BIO_push(b64, in);
        unsigned char *out_buf = calloc(in_len, sizeof(unsigned char));
        if (out_buf == NULL) return 3;
        size_t out_len;
        int r = BIO_read_ex(in, out_buf, in_len, &out_len);
        printf("rv = %d\n", r);
        printf("decoded = %s\n", out_buf);
        return 0;
    }
    ```

    Update the text of `BIO_f_base64(3)` to clarify that when the flag
    is set, the data must be all on one line (with or without a trailing
    newline character).

    Always end BN_mod_exp_mont_consttime with normal Montgomery reduction.

    This partially fixes a bug where, on x86_64, BN_mod_exp_mont_consttime
    would sometimes return m, the modulus, when it should have returned
    zero. Thanks to Guido Vranken for reporting it. It is only a partial fix
    because the same bug also exists in the "rsaz" codepath.

    The bug only affects zero outputs (with non-zero inputs), so we believe
    it has no security impact on our cryptographic functions.

    The fx is to delete lowercase bn_from_montgomery altogether, and have the
    mont5 path use the same BN_from_montgomery ending as the non-mont5 path.
    This only impacts the final step of the whole exponentiation and has no
    measurable perf impact.

    Fix a memory leak in crl_set_issuers

    This can be reproduced with my error injection patch.

    The test vector has been validated on the 1.1.1 branch
    but the issue is of course identical in all branches.

    Fix a crash in ssl_security_cert_chain

    Prior to the crash there is an out of memory error
    in X509_verify_cert which makes the chain NULL or
    empty.  The error is ignored by ssl_add_cert_chain,
    and ssl_security_cert_chain crashes due to the
    unchecked null pointer.

    This is reproducible with my error injection patch.

    The test vector has been validated on the 1.1.1 branch
    but the issue is of course identical in all branches.

    Fix a crash in asn1_item_embed_new

    This happens usually if an template object is created
    and there is an out of memory error before the ASN1_OP_NEW_POST
    method is called, but asn1_item_embed_free calls now the
    ASN1_OP_FREE_POST which may crash because the object is not
    properly initialized.  Apparently that is only an issue with
    the ASN1_OP_FREE_POST handling of crypot/x509/x_crl.c, which
    ought to be tolerant to incomplete initialized objects.

    The error can be reproduced with the reproducible error injection patch:

    Fix leakage when the cacheline is 32-bytes in CBC_MAC_ROTATE_IN_PLACE

    rotated_mac is a 64-byte aligned buffer of size 64 and rotate_offset is secret.
    Consider a weaker leakage model(CL) where only cacheline base address is leaked,
    i.e address/32 for 32-byte cacheline(CL32).

    Previous code used to perform two loads
        1. rotated_mac[rotate_offset ^ 32] and
        2. rotated_mac[rotate_offset++]
    which would leak 2q + 1, 2q for 0 <= rotate_offset < 32
    and 2q, 2q + 1 for 32 <= rotate_offset < 64

    The proposed fix performs load operations which will always leak 2q, 2q + 1 and
    selects the appropriate value in constant-time.

Suppress leaky memory warning
5c4b034 
During my testing (*), I got below stack about leaked memory.

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_public)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

```

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_private)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

As a result, the fix is similar to earlier fix 5c4b034

```

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_private)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

As a result, the fix is similar to earlier fix 5c4b034

Suppress leaky memory warning
8a33202 
During my testing (*), I got below stack about leaked memory.

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_public)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

```

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_private)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

As a result, the fix is similar to earlier fix 5c4b034

Suppress leaky memory warning
e8bafdb 
During my testing (*), I got below stack about leaked memory.

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_public)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

```

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_private)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

As a result, the fix is similar to earlier fix 5c4b034

Suppress leaky memory warning
7a5396a 
During my testing (*), I got below stack about leaked memory.

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_public)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

```

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_private)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

As a result, the fix is similar to earlier fix 5c4b034

Suppress leaky memory warning
dfaa2c0 
During my testing (*), I got below stack about leaked memory.

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_public)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

```

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_private)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

As a result, the fix is similar to earlier fix 5c4b034

Suppress leaky memory warning
c041895 
During my testing (*), I got below stack about leaked memory.

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_public)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

```

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_private)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

As a result, the fix is similar to earlier fix 5c4b034

Suppress leaky memory warning
9d2c904 
During my testing (*), I got below stack about leaked memory.

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_public)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

```

- at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage)
- this calls into Azure, then into curl, and then into OpenSSL
- curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper)
- OpenSSL initializes the random number generator and stores it in some
  random number generator context object (--> *RAND_get0_private)
- this object is registered via pthread_key_create and
  pthread_setspecific registered in TLS
- if registerAzureObjectStorage was the only place which initializes the
  RNG, we could argue that the leaked memory does not matter anyways as
  it is released after shutdown
- RAND_get0_public also registers a free handler
  (rand_delete_thread_state) that runs in TLS, so the memory is released
  also if registration is called from arbitrary other threads.

In sum: this is a false positive.

As a result, the fix is similar to earlier fix 5c4b034
