The failure of RAND_load_file was only noticed because of the heap corruption which was reported in #7499 and fixed in commit 5b4cb385 . To prevent this in the future, RAND_load_file() now explicitly checks RAND_status() and reports an error if it fails. Related-to: #7449 Reviewed-by:

When building shared libraries on Windows, we had a clash between 'libcrypto.lib' the static routine library and 'libcrypto.lib' the import library. We now change it so the static versions of our libraries get '_static' appended to their names. These will never get installed, but can still be used for our internal purposes, such as internal tests. When building non-shared, the renaming mechanism doesn't come into play. In that case, the static libraries 'libcrypto.lib' and 'libssl.lib' are installed, just as always. Fixes #7492 Reviewed-by:

This bug was introduced by #7382 which enhanced RAND_add() to accept large buffer sizes. As a consequence, RAND_add() now fails for buffer sizes less than 32 bytes (i.e. less than 256 bits). In addition, rand_drbg_get_entropy() forgets to reset the attached drbg->pool in the case of an error, which leads to the heap corruption. The problem occurred with RAND_load_file(), which reads the file in chunks of 1024 bytes each. If the size of the final chunk is less than 32 bytes, then RAND_add() fails, whence RAND_load_file() fails silently for buffer sizes n = k * 1024 + r with r = 1,...,31. This commit fixes the heap corruption only. The other issues will be addressed in a separate pull request. Thanks to Gisle Vanem for reporting this issue. Fixes #7449 Reviewed-by:

We only had targets for the "simple" shared library names (libfoo.so and not libfoo.so.x.y on Unix, import library libfoo.lib but not libfoo.dll on Windows). This has created some confusion why it wasn't possible to rebuild the less "simple" name directly (just as an example, someone who mistook the import library on Windows for a static library, removed the DLL and then found it was difficult to rebuild directly), so we change the target to include all possible names.

An unknown PSK identity could be because its actually a session resumption attempt. Sessions resumptions and external PSKs are indistinguishable so the callbacks need to fail gracefully if they don't recognise the identity. Fixes #7433 Reviewed-by:

Previously when a ClientHello arrives with a valid cookie using DTLSv1_listen() we only "peeked" at the message and left it on the underlying fd. This works fine for single threaded applications but for multi-threaded apps this does not work since the fd is typically reused for the server thread, while a new fd is created and connected for the client. By "peeking" we leave the message on the server fd, and consequently we think we've received another valid ClientHello and so we create yet another fd for the client, and so on until we run out of fds. In this new approach we remove the ClientHello and buffer it in the SSL object. Fixes #6934 Reviewed-by:

Also, some readers of the code find starting the count at 1 for EE cert confusing (since RFC5280 counts only non-self-issued intermediate CAs, but we also counted the leaf). Therefore, never count the EE cert, and adjust the path length comparison accordinly. This may be more clear to the reader. Reviewed-by:

At the bottom of https://tools.ietf.org/html/rfc5280#page-12 and top of https://tools.ietf.org/html/rfc5280#page-13 (last paragraph of above https://tools.ietf.org/html/rfc5280#section-3.3), we see: This specification covers two classes of certificates: CA certificates and end entity certificates. CA certificates may be further divided into three classes: cross-certificates, self-issued certificates, and self-signed certificates. Cross-certificates are CA certificates in which the issuer and subject are different entities. Cross-certificates describe a trust relationship between the two CAs. Self-issued certificates are CA certificates in which the issuer and subject are the same entity. Self-issued certificates are generated to support changes in policy or operations. Self- signed certificates are self-issued certificates where the digital signature may be verified by the public key bound into the certificate. Self-signed certificates are used to convey a public key for use to begin certification paths. End entity certificates are issued to subjects that are not authorized to issue certificates. that the term "self-issued" is only applicable to CAs, not end-entity certificates. In https://tools.ietf.org/html/rfc5280#section-4.2.1.9 the description of path length constraints says: The pathLenConstraint field is meaningful only if the cA boolean is asserted and the key usage extension, if present, asserts the keyCertSign bit (Section 4.2.1.3). In this case, it gives the maximum number of non-self-issued intermediate certificates that may follow this certificate in a valid certification path. (Note: The last certificate in the certification path is not an intermediate certificate, and is not included in this limit. Usually, the last certificate is an end entity certificate, but it can be a CA certificate.) This makes it clear that exclusion of self-issued certificates from the path length count applies only to some *intermediate* CA certificates. A leaf certificate whether it has identical issuer and subject or whether it is a CA or not is never part of the intermediate certificate count. The handling of all leaf certificates must be the same, in the case of our code to post-increment the path count by 1, so that we ultimately reach a non-self-issued intermediate it will be the first one (not zeroth) in the chain of intermediates.

Commit ffb46830 introduced the 'rand_serial' option. When it is used, the 'serialfile' does not get initialized, i.e. it remains a NULL pointer. This causes a crash when the NULL pointer is passed to the rotate_serial() call. This commit fixes the crash and unifies the pointer checking before calling the rotate_serial() and save_serial() commands. Fixes #7412 Reviewed-by:

In pull request #4328 the seeding of the DRBG via RAND_add()/RAND_seed() was implemented by buffering the data in a random pool where it is picked up later by the rand_drbg_get_entropy() callback. This buffer was limited to the size of 4096 bytes. When a larger input was added via RAND_add() or RAND_seed() to the DRBG, the reseeding failed, but the error returned by the DRBG was ignored by the two calling functions, which both don't return an error code. As a consequence, the data provided by the application was effectively ignored. This commit fixes the problem by a more efficient implementation which does not copy the data in memory and by raising the buffer the size limit to INT32_MAX (2 gigabytes). This is less than the NIST limit of 2^35 bits but it was chosen intentionally to avoid platform dependent problems like integer sizes and/or signed/unsigned conversion. Additionally, the DRBG is now less permissive on errors: In addition to pushing a message to the openssl error stack, it enters the error state, which forces a reinstantiation on next call. Thanks go to Dr. Falko Strenzke for reporting this issue to the openssl-security mailing list. After internal discussion the issue has been categorized as not being security relevant, because the DRBG reseeds automatically and is fully functional even without additional randomness provided by the application.

Historically (i.e., OpenSSL 1.0.x), the openssl applications would allow for empty subject attributes to be passed via the -subj argument, e.g., `opensl req -subj '/CN=joe/O=/OU=local' ...`. Commit db4c08f0 applied a badly needed rewrite to the parse_name() helper function that parses these strings, but in the process dropped a check that would skip attributes with no associated value. As a result, such strings are now treated as hard errors and the operation fails. Restore the check to skip empty attribute values and restore the historical behavior. Document the behavior for empty subject attribute values in the corresponding applications' manual pages. Reviewed-by:
