ac8673ff85 openssl: add ppc64 support
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.

12a80e44b9 openssl: always build with GOST engine support
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.

2e8a4db9b6 openssl: revert EOF detection change in 1.1.1
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.

2407b1edcc openssl: disable digests by default, misc fixes
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.

Revert the removal of the OPENSSL_ENGINE_CRYPTO symbol, currently used
by openssh.  There is an open PR to update openssh; when merged, this
symbol can be safely removed.

d971ae51a5 openssl: backport devcrypto changes from master
The patches to the /dev/crypto engine were commited to openssl master,
and will be in the next major version (3.0).

Changes:
- Optimization in computing a digest in one operation, saving an ioctl
- Runtime configuration options for the choice of algorithms to use
- Command to dump useful information about the algorithms supported by
  the engine and the system.
- Build the devcrypto engine as a dynamic module, like other engines.

The devcrypto engine is built as a separate package by default, but
options were added to allow building the engines into the main library.

2eeb2853ed openssl: optimizations based on ARCH/small flash
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
the affected platforms are source-only anyway.

098afa1e1b openssl: Enable assembler optimizations for aarch64
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...

CVE-2016-0704

s2_srvr.c overwrite the wrong bytes in the master-key when applying
Bleichenbacher protection for export cipher suites. This provides a
Bleichenbacher oracle, and could potentially allow more efficient variants of
the DROWN attack.

CVE-2016-0703

s2_srvr.c did not enforce that clear-key-length is 0 for non-export ciphers.
If clear-key bytes are present for these ciphers, they *displace* encrypted-key
bytes. This leads to an efficient divide-and-conquer key recovery attack: if
an eavesdropper has intercepted an SSLv2 handshake, they can use the server as
an oracle to determine the SSLv2 master-key, using only 16 connections to the
server and negligible computation. More importantly, this leads to a more
efficient version of DROWN that is effective against non-export ciphersuites,
and requires no significant computation.

CVE-2016-0702

A side-channel attack was found which makes use of cache-bank conflicts on
the Intel Sandy-Bridge microarchitecture which could lead to the recovery of
RSA keys. The ability to exploit this issue is limited as it relies on an
attacker who has control of code in a thread running on the same hyper-
threaded core as the victim thread which is performing decryptions.

CVE-2016-0799

The internal |fmtstr| function used in processing a "%s" format string in
the BIO_*printf functions could overflow while calculating the length of a
string and cause an OOB read when printing very long strings. Additionally
the internal |doapr_outch| function can attempt to write to an OOB memory
location (at an offset from the NULL pointer) in the event of a memory
allocation failure. In 1.0.2 and below this could be caused where the size
of a buffer to be allocated is greater than INT_MAX. E.g. this could be in
processing a very long "%s" format string. Memory leaks can also occur.
The first issue may mask the second issue dependent on compiler behaviour.
These problems could enable attacks where large amounts of untrusted data is
passed to the BIO_*printf functions. If applications use these functions in
this way then they could be vulnerable. OpenSSL itself uses these functions
when printing out human-readable dumps of ASN.1 data. Therefore applications
that print this data could be vulnerable if the data is from untrusted sources.
OpenSSL command line applications could also be vulnerable where they print out
ASN.1 data, or if untrusted data is passed as command line arguments. Libssl is
not considered directly vulnerable. Additionally certificates etc received via
remote connections via libssl are also unlikely to be able to trigger these
issues because of message size limits enforced within libssl.

CVE-2016-0797

In the BN_hex2bn function the number of hex digits is calculated using an int
value |i|. Later |bn_expand| is called with a value of |i * 4|. For large
values of |i| this can result in |bn_expand| not allocating any memory because
|i * 4| is negative. This can leave the internal BIGNUM data field as NULL
leading to a subsequent NULL ptr deref. For very large values of |i|, the
calculation |i * 4| could be a positive value smaller than |i|. In this case
memory is allocated to the internal BIGNUM data field, but it is insufficiently
sized leading to heap corruption. A similar issue exists in BN_dec2bn. This
could have security consequences if BN_hex2bn/BN_dec2bn is ever called by user
applications with very large untrusted hex/dec data. This is anticipated to be
a rare occurrence. All OpenSSL internal usage of these functions use data that
is not expected to be untrusted, e.g. config file data or application command
line arguments. If user developed applications generate config file data based
on untrusted data then it is possible that this could also lead to security
consequences. This is also anticipated to be rare.

CVE-2016-0798

The SRP user database lookup method SRP_VBASE_get_by_user had confusing memory
management semantics; the returned pointer was sometimes newly allocated, and
sometimes owned by the callee. The calling code has no way of distinguishing
these two cases. Specifically, SRP servers that configure a secret seed to hide
valid login information are vulnerable to a memory leak: an attacker connecting
with an invalid username can cause a memory leak of around 300 bytes per
connection. Servers that do not configure SRP, or configure SRP but do not
configure a seed are not vulnerable. In Apache, the seed directive is known as
SSLSRPUnknownUserSeed. To mitigate the memory leak, the seed handling in
SRP_VBASE_get_by_user is now disabled even if the user has configured a seed.
Applications are advised to migrate to SRP_VBASE_get1_by_user. However, note
that OpenSSL makes no strong guarantees about the indistinguishability of valid
and invalid logins. In particular, computations are currently not carried out
in constant time.

CVE-2016-0705

A double free bug was discovered when OpenSSL parses malformed DSA private keys
and could lead to a DoS attack or memory corruption for applications that
receive DSA private keys from untrusted sources. This scenario is considered
rare.

CVE-2016-0800

A cross-protocol attack was discovered that could lead to decryption of TLS
sessions by using a server supporting SSLv2 and EXPORT cipher suites as a
Bleichenbacher RSA padding oracle. Note that traffic between clients and non-
vulnerable servers can be decrypted provided another server supporting SSLv2
and EXPORT ciphers (even with a different protocol such as SMTP, IMAP or POP)
shares the RSA keys of the non-vulnerable server. This vulnerability is known
as DROWN (CVE-2016-0800). Recovering one session key requires the attacker to
perform approximately 2^50 computation, as well as thousands of connections to
the affected server. A more efficient variant of the DROWN attack exists
against unpatched OpenSSL servers using versions that predate 1.0.2a, 1.0.1m,
1.0.0r and 0.9.8zf released on 19/Mar/2015 (see CVE-2016-0703 below). Users can
avoid this issue by disabling the SSLv2 protocol in all their SSL/TLS servers,
if they've not done so already. Disabling all SSLv2 ciphers is also sufficient,
provided the patches for CVE-2015-3197 (fixed in OpenSSL 1.0.1r and 1.0.2f)
have been deployed. Servers that have not disabled the SSLv2 protocol, and are
not patched for CVE-2015-3197 are vulnerable to DROWN even if all SSLv2
ciphers are nominally disabled, because malicious clients can force the use of
SSLv2 with EXPORT ciphers. OpenSSL 1.0.2g and 1.0.1s deploy the following
mitigation against DROWN: SSLv2 is now by default disabled at build-time.
Builds that are not configured with "enable-ssl2" will not support SSLv2.
Even if "enable-ssl2" is used, users who want to negotiate SSLv2 via the
version-flexible SSLv23_method() will need to explicitly call either of:
SSL_CTX_clear_options(ctx, SSL_OP_NO_SSLv2); or SSL_clear_options(ssl,
SSL_OP_NO_SSLv2); as appropriate. Even if either of those is used, or the
application explicitly uses the version-specific SSLv2_method() or its client
or server variants, SSLv2 ciphers vulnerable to exhaustive search key recovery
have been removed. Specifically, the SSLv2 40-bit EXPORT ciphers, and SSLv2
56-bit DES are no longer available. In addition, weak ciphers in SSLv3 and up
are now disabled in default builds of OpenSSL. Builds that are not configured
with "enable-weak-ssl-ciphers" will not provide any "EXPORT" or "LOW" strength
ciphers.

48d9137d31 openssl: update to v1.0.2d (CVE-2015-1793)
During certificate verification, OpenSSL (starting from version 1.0.1n and
1.0.2b) will attempt to find an alternative certificate chain if the first
attempt to build such a chain fails. An error in the implementation of this
logic can mean that an attacker could cause certain checks on untrusted
certificates to be bypassed, such as the CA flag, enabling them to use a valid
leaf certificate to act as a CA and "issue" an invalid certificate.

This issue will impact any application that verifies certificates including
SSL/TLS/DTLS clients and SSL/TLS/DTLS servers using client authentication.
