Improve handling of low entropy at start up from /dev/urandom by waiting for a read(2) call on /dev/random to succeed. Once one such call has succeeded, a shared memory segment is created and persisted as an indicator to other processes that /dev/urandom is properly seeded. This does not fully prevent against attacks weakening the entropy source. An attacker who has control of the machine early in its boot sequence could create the shared memory segment preventing detection of low entropy conditions. However, this is no worse than the current situation. An attacker would also be capable of removing the shared memory segment and causing seeding to reoccur resulting in a denial of service attack. This is partially mitigated by keeping the shared memory alive for the duration of the process's existence. Thus, an attacker would not only need to have called call shmctl(2) with the IPC_RMID command but the system must subsequently enter a state where no instances of libcrypto exist in any process. Even one long running process will prevent this attack. The System V shared memory calls used here go back at least as far as Linux kernel 2.0. Linux kernels 4.8 and later, don't have a reliable way to detect that /dev/urandom has been properly seeded, so a failure is raised for this case (i.e. the getentropy(2) call has already failed).

Actually supply a chain and then test: 1) A successful check of both the ee and chain certs 2) A failure to check the ee cert 3) A failure to check a chain cert Reviewed-by:

The function SSL_check_chain() can be used by applications to check that a cert and chain is compatible with the negotiated parameters. This could be useful (for example) from the certificate callback. Unfortunately this function was applying TLSv1.2 sig algs rules and did not work correctly if TLSv1.3 was negotiated. We refactor tls_choose_sigalg to split it up and create a new function find_sig_alg which can (optionally) take a certificate and key as parameters and find an appropriate sig alg if one exists. If the cert and key are not supplied then we try to find a cert and key from the ones we have available that matches the shared sig algs. Reviewed-by:

A local 'make clean' did some sweeping removals of files execpt for the .git directory. This is a little too sweeping, as other dotted files might be cleaned away if they happen to match the pattern that's searched for. An example is a symlink .dir-locals.el that would keep disappearing if you build in the source tree and do a make clean... So we change this to leave all dotted files alone. Our builds do not produce such files anyway, so this is a harmless (or rather, less harmful) change. Reviewed-by:

A default digest of SHA256 was being returned for RSA PSS even if the PSS parameters indicated a different digest must be used. We change this so that the correct default digest is returned and additionally mark this as mandatory for PSS. This bug had an impact on sig alg selection in libssl. Due to this issue an incorrect sig alg might be selected in the event that a server is configured with an RSA-PSS cert with parameter restrictions. Fixes #9545 Reviewed-by:

At some point in the past do_ssl3_write() used to return the number of bytes written, or a value <= 0 on error. It now just returns a success/ error code and writes the number of bytes written to |tmpwrit|. The SSL_MODE_RELEASE_BUFFERS code was still looking at the return code for the number of bytes written rather than |tmpwrit|. This has the effect that the buffers are not released when they are supposed to be. Fixes #9490 Reviewed-by:

tls_parse_stoc_key_share was generating a new EVP_PKEY public/private keypair and then overrides it with the server public key, so the generation was a waste anyway. Instead, it should create a parameters-only EVP_PKEY. (This is a consequence of OpenSSL using the same type for empty key, empty key with key type, empty key with key type + parameters, public key, and private key. As a result, it's easy to mistakenly mix such things up, as happened here.) Reviewed-by:
