engine.mk is supposed to be included by engine packages, but it will not
be present in the SDK in the same place as in the main repository.
Move it to include/openssl-engine.mk to avoid this.

This uses uci to configure engines, by generating a list of enabled
engines in /var/etc/ssl/engines.cnf from engines configured in
/etc/config/openssl:
config engine 'devcrypto'
option enabled '1'
Currently the only options implemented are 'enabled', which defaults to
true and enables the named engine, and the 'force' option, that enables
the engine even if the init script thinks the engine does not exist.
The existence test is to check for either a configuration file
/etc/ssl/engines.cnf.d/%ENGINE%.cnf, or a shared object file
/usr/lib/engines-1.1/%ENGINE%.so.
The engine list is generated by an init script which is set to run after
'log' because it informs the engines being enabled or skipped. It
should run before any service using OpenSSL as the crypto library,
otherwise the service will not use any engine.

This enables an engine during its package's installation, by adding it
to the engines list in /etc/ssl/engines.cnf.d/engines.cnf.
The engine build system was reworked, with the addition of an engine.mk
file that groups some of the engine packages' definitions, and could be
used by out of tree engines as well.

This changes the configuration of engines from the global openssl.cnf to
files in the /etc/ssl/engines.cnf.d directory. The engines.cnf file has
the list of enabled engines, while each engine has its own configuration
file installed under /etc/ssl/engines.cnf.d.

Backport an upstream patch that adds support for ELFv2 ABI on big endian
ppc64. As musl only supports ELFv2 ABI on ppc64 regardless of
endianness, this is required to be able to build OpenSSL for ppc64be.
Modify our targets patch to add linux-powerpc64-openwrt, which will use
the linux64v2 perlasm scheme. This will probably break the combination
ppc64 with glibc, but as we really only want to support musl, this
shouldn't be a problem.

Before this commit, it was assumed that mkhash is in the PATH. While
this was fine for the normal build workflow, this led to some issues if
make TOPDIR="$(pwd)" -C "$pkgdir" compile
was called manually. In most of the cases, I just saw warnings like this:
make: Entering directory '/home/.../package/gluon-status-page'
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
bash: line 1: mkhash: command not found
[...]
While these were only warnings and the package still compiled sucessfully,
I also observed that some package even fail to build because of this.
After applying this commit, the variable $(MKHASH) is introduced. This
variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the
correct path.

The packages feed has a proposed package for a GOST engine, which needs
support from the main openssl library. It is a default option in
OpenSSL. All that needs to be done here is to not disable it.
Package increases by a net 1-byte, so it is not really really worth
keeping this optional.
This commit also includes a commented-out example engine configuration
in openssl.cnf, as it is done for other available engines.

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.
