Add value_barriers in constant time select functions

The barriers prevent the compiler from narrowing down the
possible value range of the mask and ~mask in the select

Adding Test.pm with workaround for Perl abs2rel bug

If SRCTOP != BLDTOP, and SRCTOP is given in relative form, e.g.
"./config ../openssl", then a bug in Perl's abs2rel may trigger that directory-
rewriting in __cwd results in wrong entries in %directories under certain

There should not be any need to go to a higher directory from BLDDIR or SRCDIR,
so it should be OK to use them in their absolute form, also resolving all

When abs2rel gets a path argument with ..s that are crossing over the ..s
trailing the base argument, the result is wrong.

Move 'shared_sigalgs' from cert_st to ssl_st

It was only ever in cert_st because ssl_st was a public structure
and could not be modified without breaking the API.  However, both
structures are now opaque, and thus we can freely change their layout
without breaking applications.  In this case, keeping the shared
sigalgs in the SSL object prevents complications wherein they would
inadvertently get cleared during SSL_set_SSL_CTX() (e.g., as run

Revert the DEVRANDOM_WAIT feature

The DEVRANDOM_WAIT feature added a select() call to wait for the
`/dev/random` device to become readable before reading from the
`/dev/urandom` device. It was introduced in commit 38023b87f037
in order to mitigate the fact that the `/dev/urandom` device
does not block until the initial seeding of the kernel CSPRNG
has completed, contrary to the behaviour of the `getrandom()`
system call.

It turned out that this change had negative side effects on
performance which were not acceptable. After some discussion it
was decided to revert this feature and leave it up to the OS
resp. the platform maintainer to ensure a proper initialization
during early boot time.

Fixes #9078

build_SYS_str_reasons: Fix a crash caused by overlong locales

The 4 kB SPACE_SYS_STR_REASONS in crypto/err/err.c isn't enough for some locales.
The Russian locales consume 6856 bytes, Ukrainian even 7000.

build_SYS_str_reasons() contains an overflow check:

if (cnt > sizeof(strerror_pool))
    cnt = sizeof(strerror_pool);

But since commit 9f15e5b911ba6053e09578f190354568e01c07d7 it no longer
works as cnt is incremented once more after the condition.

cnt greater than sizeof(strerror_pool) results in an unbounded
OPENSSL_strlcpy() in openssl_strerror_r(), eventually causing a crash.

When the first received error string was empty or contained only
spaces, cur would move in front of the start of the strerror_pool.

Also don't call openssl_strerror_r when the pool is full.

Defer sending a KeyUpdate until after pending writes are complete

If we receive a KeyUpdate message (update requested) from the peer while
we are in the middle of a write, we should defer sending the responding
KeyUpdate message until after the current write is complete. We do this
by waiting to send the KeyUpdate until the next time we write and there is
no pending write data.

This does imply a subtle change in behaviour. Firstly the responding
KeyUpdate message won't be sent straight away as it is now. Secondly if
the peer sends multiple KeyUpdates without us doing any writing then we
will only send one response, as opposed to previously where we sent a
response for each KeyUpdate received.

Allow specifying the tag after AAD in CCM mode

This change allows to pass the authentication tag after specifying
the AAD in CCM mode. This is already true for the other two supported
AEAD modes (GCM and OCB) and it seems appropriate to match the
behavior.

GCM and OCB also support to set the tag at any point before the call
to `EVP_*Final`, but this won't work for CCM due to a restriction
imposed by section 2.6 of RFC3610: The tag must be set before
actually decrypting data.

This commit also adds a test case for setting the tag after supplying
plaintext length and AAD.

openssl cms: add error message if operation option is missing

If the `openssl cms` command is called without specifying an
operation option, it replies with the following laconic error message:

    cms: Use -help for summary.

This commit adds a helpful error message:

    No operation option (-encrypt|-decrypt|-sign|-verify|...) specified.
