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.

to ignore that field even if it is wrong. The recent changes to the read
record layer in PR #18132 made the record layer stricter and it was
checking that the legacy_record_version was the correct value. This

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

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

- Don't unpad records, check the outer record type, or extract the
inner record type from TLS 1.3 records handled by the kernel. KTLS
performs all of these steps and returns the inner record type in the
TLS header.
- When checking the length of a received TLS 1.3 record don't allow
for the extra byte for the nested record type when KTLS is used.
- Pass a pointer to the record type in the TLS header to the
SSL3_RT_INNER_CONTENT_TYPE message callback. For KTLS, the old
pointer pointed to the last byte of payload rather than the record
type. For the non-KTLS case, the TLS header has been updated with
the inner type before this callback is invoked.

When KTLS receive is enabled, pending data may still be present due to
read ahead. This data must still be processed the same as records
received without KTLS. To ease readability (especially in
consideration of additional checks which will be added for TLS 1.3),
add a helper variable 'using_ktls' that is true when the KTLS receive
path is being used to receive a record.

In some corner cases the check for packets

when KTLS is initially enabled, when some

Add at least some tests for KTLS, since we have

Sometimes this function gets called when the buffers have already been
set up. If there is already a partial packet in the read buffer then the
packet pointer will be set to an incorrect value. The packet pointer already
gets reset to the correct value when we first read a packet anyway, so we
don't also need to do it in ssl3_setup_read_buffer.

Add a "where did this EVP_{CIPHER,MD} come from" flag: global, via fetch,
or via EVP_{CIPHER,MD}_meth_new. Update EVP_{CIPHER,MD}_free to handle all
three origins. The flag is deliberately right before some function pointers,
so that compile-time failures (int/pointer) will occur, as opposed to
taking a bit in the existing "flags" field. The "global variable" flag
is non-zero, so the default case of using OPENSSL_zalloc (for provider
ciphers), will do the right thing. Ref-counting is a no-op for

DTLS by design ignores records/packets with bad MAC or failed AEAD tag
validation. However, recent changes to have provided cipher
implementations caused tls1_enc() to leave an entry on the error queue
for invalid GCM tags, e.g.:
800BEAEF487F0000:error::Provider routines:gcm_stream_update:cipher operation failed:providers/implementations/ciphers/ciphercommon_gcm.c:306
The BoringSSL tests check for entries on the error queue with
SSL_get_error() and so we were seeing spurious test failures
due to the additional item on the error queue. To avoid leaving
such spurious entries on the error queue, set a mark before calling
the ssl3_enc 'enc' method, and pop to that mark before ignoring
invalid packets.
