MrRurikov 8ae4b23634 bio_print.c: Delete unreachable code at lines 710 and 711
CLA: trivial

The purpose of adding the conditional operator on line 710 is to check
if the value of the variable 'fplace' exceeds the size of the array
'fconvert', and to reduce the value of 'fplace' by 1, so that later on
we can set the value to zero of the array element with the index 'fplace'
and not make any calls beyond the array edges.

However, the condition on line 710 will always be false, because
the size of 'fconvert' is strictly specified at the beginning of
the 'fmtfp()' function (line 571), so it is reasonable to remove
this conditional operator, as well as the unreachable decrementation
code of the variable 'fplace'.

Richard Levitte a8681703d4 bss_dgram.c: Use BIO_ADDR_sockaddr() and BIO_ADDR_sockaddr_size()
Especially, it's important to use BIO_ADDR_sockaddr_size() instead of
taking sizeof(addr), as BIO_ADDR is a union of several sockaddr variants
with different sizes, and some sendto() implementations are very picky
that the size is correct for the indicated sockaddr family.

Maxim Mikityanskiy cd715b7e7f Add support for KTLS zerocopy sendfile on Linux
TLS device offload allows to perform zerocopy sendfile transmissions.
FreeBSD provides this feature by default, and Linux 5.19 introduced it
as an opt-in. Zerocopy improves the TX rate significantly, but has a
side effect: if the underlying file is changed while being transmitted,
and a TCP retransmission happens, the receiver may get a TLS record
containing both new and old data, which leads to an authentication
failure and termination of connection. This effect is the reason Linux
makes a copy on sendfile by default.

This commit adds support for TLS zerocopy sendfile on Linux disabled by
default to avoid any unlikely backward compatibility issues on Linux,
although sacrificing consistency in OpenSSL's behavior on Linux and
FreeBSD. A new option called KTLSTxZerocopySendfile is added to enable
the new zerocopy behavior on Linux. This option should be used when the
the application guarantees that the file is not modified during
transmission, or it doesn't care about breaking the connection.

The related documentation is also added in this commit. The unit test
added doesn't test the actual functionality (it would require specific
hardware and a non-local peer), but solely checks that it's possible to
set the new option flag.

Richard Levitte e077455e9e Stop raising ERR_R_MALLOC_FAILURE in most places
Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and
at least handle the file name and line number they are called from,
there's no need to report ERR_R_MALLOC_FAILURE where they are called
directly, or when SSLfatal() and RLAYERfatal() is used, the reason
`ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`.

There were a number of places where `ERR_R_MALLOC_FAILURE` was reported
even though it was a function from a different sub-system that was
called.  Those places are changed to report ERR_R_{lib}_LIB, where
{lib} is the name of that sub-system.
Some of them are tricky to get right, as we have a lot of functions
that belong in the ASN1 sub-system, and all the `sk_` calls or from
the CRYPTO sub-system.

Some extra adaptation was necessary where there were custom OPENSSL_malloc()
wrappers, and some bugs are fixed alongside these changes.

Bernd Edlinger 598bd77415 Fix KTLS with BIO_new_connect
When a socket connection is done using BIO_new_connect,
the ktls_enable is done too early, and fails with ENOTCONN.
Therefore the KLTS ioctl will fail later with ENOPROTOOPT.
Fix that by doing the ktls_enable after the connection
succeeded, not when the socket is created as that will
always fail.

One example where this happens is doit_localhost in
test/ssl_old_test.c, and therefore, contrary to the expectation
the -client_ktls option did never enable the client KTLS
connection, but this was not noticed, because there was no
diagnostic output, and it was only visible with strace output.

Also enhanced the ssl_old_test -client_ktls/-server_ktls
options together with -v option to print a summary line
if and how KTLS was negotiated in server and client.

While I am already there adjusted the usage info of
the -s_cert, -s_key commands, and allow -time to print the
timings of ktls connections.

Therefore, just checking the member of 'bcgbl' is not enough.
We need to check 'bcgbl' itself too in order to avoid the dereference of
the NULL pointer.
And the caller of ossl_bio_init_core(), OSSL_LIB_CTX_new_from_dispatch()
in `crypto/context.c`, has already checked return value and dealed with
the situation if it returns 0.
