This fixes 4 security vulnerabilities/bugs:
- CVE-2021-2839 - SSLv2 vulnerability. Openssl 1.1.1 does not support
SSLv2, but the affected functions still exist. Considered just a bug.
- CVE-2021-2840 - calls EVP_CipherUpdate, EVP_EncryptUpdate and
EVP_DecryptUpdate may overflow the output length argument in some
cases where the input length is close to the maximum permissable
length for an integer on the platform. In such cases the return value
from the function call will be 1 (indicating success), but the output
length value will be negative.
- CVE-2021-2841 - The X509_issuer_and_serial_hash() function attempts to
create a unique hash value based on the issuer and serial number data
contained within an X509 certificate. However it was failing to
correctly handle any errors that may occur while parsing the issuer
field (which might occur if the issuer field is maliciously
constructed). This may subsequently result in a NULL pointer deref and
a crash leading to a potential denial of service attack.
- Fixed SRP_Calc_client_key so that it runs in constant time. This could
be exploited in a side channel attack to recover the password.
The 3 CVEs above are currently awaiting analysis.

There were two changes between 1.1.1e and 1.1.1f:
- a change in BN prime generation to avoid possible fingerprinting of
newly generated RSA modules
- the patch reversing EOF detection we had already applied.
Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com>
This adds patches to avoid possible application breakage caused by a
change in behavior introduced in 1.1.1e. It affects at least nginx,
which logs error messages such as:
nginx[16652]: [crit] 16675#0: *358 SSL_read() failed (SSL: error:
4095126:SSL routines:ssl3_read_n:unexpected eof while reading) while
keepalive, client: xxxx, server: [::]:443
Openssl commits db943f4 (Detect EOF while reading in libssl), and
22623e0 (Teach more BIOs how to handle BIO_CTRL_EOF) changed the
behavior when encountering an EOF in SSL_read(). Previous behavior was
to return SSL_ERROR_SYSCALL, but errno would still be 0. The commits
being reverted changed it to SSL_ERRO_SSL, and add an error to the
stack, which is correct. Unfortunately this affects a number of
applications that counted on the old behavior, including nginx.
The reversion was discussed in openssl/openssl#11378, and implemented as
PR openssl/openssl#11400.

The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.
To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
Enable engine support by default. Right now, some packages require
this, so it is always enabled by the bots. Many packages will compile
differently when engine support is detected, needing engine symbols from
the libraries.
However, being off by default, a user compiling its own image will fail
to run some popular packages from the official repo.
Note that disabling engines did not work in 1.0.2, so this problem never
showed up before.
NPN support has been removed in major browsers & servers, and has become

Openssh uses digest contexts across forks, which is not supported by the
/dev/crypto engine. The speed of digests is usually not worth enabling
them anyway. This changes the default of the DIGESTS option to NONE, so
the user still has the option to enable them.
Added another patch related to the use of encryption contexts across
forks, that ignores a failure to close a previous open session when
reinitializing a context, instead of failing the reinitialization.
Added a link to the Cryptographic Hardware Accelerators document to the
engine pacakges description, to provide more detailed instructions to
configure the engines.

Add a patch to enable the option to change the default ciphersuite list
ordering to prefer ChaCha20 over AES-GCM. This is used by default for
all platforms, except for x86_64 and aarch64. The assumption is that
only the latter have AES-specific CPU instructions and asm code that
uses them in openssl. Chacha20Poly1305 is 3x faster than AES-256 in
systems without AES instructions, with an equivalent strength.
Disable error messages by default except for devices with small flash or
RAM, to aid debugging.
Disable ASM by default on arm platform with small flash. Size
difference on mips and powerpc, the other platforms with small flash
devices, are not really relevant (using 100K as a threshold). All of

In the case of upstream libraries, set the ABI_VERSION variable to the
soname value of the first version version after the last backwards
incompatible change.
For custom OpenWrt libraries, set the ABI_VERSION to the date of the
last Git commit doing backwards incompatible changes to the source,
such as changing function singatures or dropping exported symbols.
The soname values have been determined by either checking
https://abi-laboratory.pro/index.php?view=tracker or - in the case
of OpenWrt libraries - by carefully reviewing the changes made to
header files thorough the corresponding Git history.
In the future, the ABI_VERSION values must be bumped whenever the
library is updated to an incpompatible version but not with every
package update, in order to reduce the dependency churn in the
binary package repository.

Some package (e.g. libunbound) depend on OPENSSL_WITH_DEPRECATED. In some
situations it may happen that libunbound and openssl are only pulled in as
build dependencies, but are not enabled in .config.
In such cases, the defaults of symbols like OPENSSL_WITH_DEPRECATED are
ignored (as the whole symbol depends on PACKAGE_libopenssl), and config
symbol dependencies of libunbound aren't effective either (as libunbound
is not actually enabled).
This commit works around the issue by introducing a hidden negated symbol
OPENSSL_NO_DEPRECATED, which is always disabled when PACKAGE_libopenssl is
disabled, and ensures that OpenSSL is built with deprecated APIs in this
case. A user can still manage to break the build by explicitly enabling
libopenssl and disabling OPENSSL_WITH_DEPRECATED; the interaction between
build dependencies and config symbols will require further discussion.

OpenSSL is built with the generic linux settings for most targets,
including aarch64. These generic settings are designed for 32-bit CPU and
provide no assembler optmization: this is widely suboptimal for aarch64.
This patch simply switches to the aarch64 settings that are already
available in OpenSSL.
Here is the output of "openssl speed" before the optimization, with
"(...)" representing build flags that didn't change:
OpenSSL 1.0.2l 25 May 2017
options:bn(64,32) rc4(ptr,char) des(idx,cisc,2,int) aes(partial) blowfish(ptr)
compiler: aarch64-openwrt-linux-musl-gcc (...)
And after this patch, OpenSSL uses 64 bit mode and assembler optimizations:
OpenSSL 1.0.2l 25 May 2017
options:bn(64,64) rc4(ptr,char) des(idx,cisc,2,int) aes(partial) blowfish(ptr)
compiler: aarch64-openwrt-linux-musl-gcc (...) -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM

For some reason AES and blowfish do not benefit, but SHA performance
improves between 1.7x and 15x. SHA256 clearly benefits the most from the
optimization (4.5x on small blocks, 15x on large blocks!).

Blowfish does not seem to have assembler optimization at all, and SHA
still benefits (between 1.6x and 14.5x) but is generally slower than in
non-EVP mode.
However, AES performance is improved between 5.5x and 27.5x, which is
really impressive! For aes-128-cbc on large blocks, a core i7-6600U
@2.60GHz is only twice as fast...
