openssl: fix CVE-2023-464 and CVE-2023-465
Apply two patches fixing low-severity vulnerabilities related to
certificate policies validation:

- Excessive Resource Usage Verifying X.509 Policy Constraints
  (CVE-2023-0464)
  Severity: Low
  A security vulnerability has been identified in all supported versions
  of OpenSSL related to the verification of X.509 certificate chains
  that include policy constraints.  Attackers may be able to exploit
  this vulnerability by creating a malicious certificate chain that
  triggers exponential use of computational resources, leading to a
  denial-of-service (DoS) attack on affected systems.
  Policy processing is disabled by default but can be enabled by passing
  the `-policy' argument to the command line utilities or by calling the
  `X509_VERIFY_PARAM_set1_policies()' function.

- Invalid certificate policies in leaf certificates are silently ignored
  (CVE-2023-0465)
  Severity: Low
  Applications that use a non-default option when verifying certificates
  may be vulnerable to an attack from a malicious CA to circumvent
  certain checks.
  Invalid certificate policies in leaf certificates are silently ignored
  by OpenSSL and other certificate policy checks are skipped for that
  certificate.  A malicious CA could use this to deliberately assert
  invalid certificate policies in order to circumvent policy checking on
  the certificate altogether.
  Policy processing is disabled by default but can be enabled by passing
  the `-policy' argument to the command line utilities or by calling the
  `X509_VERIFY_PARAM_set1_policies()' function.

Note: OpenSSL also released a fix for low-severity security advisory
CVE-2023-466.  It is not included here because the fix only changes the
documentation, which is not built nor included in any OpenWrt package.

Due to the low-severity of these issues, there will be not be an
immediate new release of OpenSSL.

openssl: add legacy provider
This adapts the engine build infrastructure to allow building providers,
and packages the legacy provider.  Providers are the successors of
engines, which have been deprecated.

The legacy provider supplies OpenSSL implementations of algorithms that
have been deemed legacy, including DES, IDEA, MDC2, SEED, and Whirlpool.

Even though these algorithms are implemented in a separate package,
their removal makes the regular library smaller by 3%, so the build
options will remain to allow lean custom builds.  Their defaults will
change to 'y' if not bulding for a small flash, so that the regular
legacy package will contain a complete set of algorithms.

The engine build and configuration structure was changed to accomodate
providers, and adapt to the new style of openssl.cnf in version 3.0.

There is not a clean upgrade path for the /etc/ssl/openssl.cnf file,
installed by the openssl-conf package.  It is recommended to rename or
remove the old config file when flashing an image with the updated
openssl-conf package, then apply the changes manually.

An old openssl.cnf file will silently work, but new engine or provider
packages will not be enabled.  Any remaining engine config files under
/etc/ssl/engines.cnf.d can be removed.

On the build side, the include file used by engine packages was renamed
to openssl-module.mk, so the engine packages in other feeds need to
adapt.

openssl: avoid OPENSSL_SMALL_FOOTPRINT, no-asm
Building openssl with OPENSSL_SMALL_FOOTPRINT yelds only from 1% to 3%
decrease in size, dropping performance from 2% to 91%, depending on the
target and algorithm.

For example, using AES256-GCM with 1456-bytes operations, X86_64 appears
to be the least affected with 2% performance penalty and 1% reduction in
size; mips drops performance by 13%, size by 3%;  Arm drops 29% in
performance, 2% in size.

On aarch64, it slows down ghash so much that I consider it broken
(-91%).  SMALL_FOOTPRINT will reduce AES256-GCM performance by 88%, and
size by only 1%.  It makes an AES-capable CPU run AES128-GCM at 35% of
the speed of Chacha20-Poly1305:

Block-size=1456 bytes   AES256-GCM   AES128-GCM  ChaCha20-Poly1305
SMALL_FOOTPRINT           62014.44     65063.23          177090.50
regular                  504220.08    565630.28          182706.16

OpenSSL 1.1.1 numbers are about the same, so this should have been
noticed a long time ago.

This creates an option to use OPENSSL_SMALL_FOOTPRINT, but it is turned
off by default unless SMALL_FLASH or LOW_MEMORY_FOOTPRINT is used.

Compiling with -O3 instead of -Os, for comparison, will increase size by
about 14-15%, with no measureable effect on AES256-GCM performance, and
about 2% increase in Chacha20-Poly1305 performance on Aarch64.

There are no Arm devices with the small flash feature, so drop the
conditional default.  The package is built on phase2, so even if we
include an Arm device with small flash later, a no-asm library would
have to be built from source anyway.

treewide: add support for "gc-sections" in PKG_BUILD_FLAGS
This reduces open coding and allows to easily add a knob to
enable it treewide, where chosen packages can still opt-out via
"no-gc-sections".

Note: libnl, mbedtls and opkg only used the CFLAGS part without the
LDFLAGS counterpart. That doesn't help at all if the goal is to produce
smaller binaries. I consider that an accident, and this fixes it.

Note: there are also packages using only the LDFLAGS part. I didn't
touch those, as gc might have been disabled via CFLAGS intentionally.

openssl: fix sysupgrade failure with devcrypto
The bump to 3.0.8 inadvertently removed patches that are needed here,
but were not adopted upstream.  The most important one changes the
default value of the DIGESTS setting from ALL to NONE.  The absence of
this patch causes a sysupgrade failure while the engine is in use with
digests enabled.  When this happens, the system fails to boot with a
kernel panic.

Also, explicitly set DIGESTS to NONE in the provided config file, and
change the default ciphers setting to disable ECB, which has been
recommended for a long time and may cause trouble with some apps.

The config file change by itself is not enough because the config file
may be preserved during sysupgrade.

For people affected by this bug:

You can either:
1. remove, the libopenssl-devcrypto package
2. disable the engine in /etc/config/openssl;
3. change /etc/ssl/engines.cnf.d/devcrypto.cnf to set DIGESTS=NONE;
4. update libopenssl-devcrypto to >=3.0.8-3

However, after doing any of the above, **you must reboot the device
before running sysupgrade** to ensure no running application is using
the engine.  Running `/etc/init.d/openssl restart` is not enough.

4ae86b3358 openssl: bump to 1.1.1t
Removed upstreamed patch: 010-padlock.patch

Changes between 1.1.1s and 1.1.1t [7 Feb 2023]

  *) Fixed X.400 address type confusion in X.509 GeneralName.

     There is a type confusion vulnerability relating to X.400 address processing
     inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1_STRING
     but subsequently interpreted by GENERAL_NAME_cmp as an ASN1_TYPE. This
     vulnerability may allow an attacker who can provide a certificate chain and
     CRL (neither of which need have a valid signature) to pass arbitrary
     pointers to a memcmp call, creating a possible read primitive, subject to
     some constraints. Refer to the advisory for more information. Thanks to
     David Benjamin for discovering this issue. (CVE-2023-0286)

     This issue has been fixed by changing the public header file definition of
     GENERAL_NAME so that x400Address reflects the implementation. It was not
     possible for any existing application to successfully use the existing
     definition; however, if any application references the x400Address field
     (e.g. in dead code), note that the type of this field has changed. There is
     no ABI change.
     [Hugo Landau]

  *) Fixed Use-after-free following BIO_new_NDEF.

     The public API function BIO_new_NDEF is a helper function used for
     streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL
     to support the SMIME, CMS and PKCS7 streaming capabilities, but may also
     be called directly by end user applications.

     The function receives a BIO from the caller, prepends a new BIO_f_asn1
     filter BIO onto the front of it to form a BIO chain, and then returns
     the new head of the BIO chain to the caller. Under certain conditions,
     for example if a CMS recipient public key is invalid, the new filter BIO
     is freed and the function returns a NULL result indicating a failure.
     However, in this case, the BIO chain is not properly cleaned up and the
     BIO passed by the caller still retains internal pointers to the previously
     freed filter BIO. If the caller then goes on to call BIO_pop() on the BIO
     then a use-after-free will occur. This will most likely result in a crash.
     (CVE-2023-0215)
     [Viktor Dukhovni, Matt Caswell]

  *) Fixed Double free after calling PEM_read_bio_ex.

     The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and
     decodes the "name" (e.g. "CERTIFICATE"), any header data and the payload
     data. If the function succeeds then the "name_out", "header" and "data"
     arguments are populated with pointers to buffers containing the relevant
     decoded data. The caller is responsible for freeing those buffers. It is
     possible to construct a PEM file that results in 0 bytes of payload data.
     In this case PEM_read_bio_ex() will return a failure code but will populate
     the header argument with a pointer to a buffer that has already been freed.
     If the caller also frees this buffer then a double free will occur. This
     will most likely lead to a crash.

     The functions PEM_read_bio() and PEM_read() are simple wrappers around
     PEM_read_bio_ex() and therefore these functions are also directly affected.

     These functions are also called indirectly by a number of other OpenSSL
     functions including PEM_X509_INFO_read_bio_ex() and
     SSL_CTX_use_serverinfo_file() which are also vulnerable. Some OpenSSL
     internal uses of these functions are not vulnerable because the caller does
     not free the header argument if PEM_read_bio_ex() returns a failure code.
     (CVE-2022-4450)
     [Kurt Roeckx, Matt Caswell]

  *) Fixed Timing Oracle in RSA Decryption.

     A timing based side channel exists in the OpenSSL RSA Decryption
     implementation which could be sufficient to recover a plaintext across
     a network in a Bleichenbacher style attack. To achieve a successful
     decryption an attacker would have to be able to send a very large number
     of trial messages for decryption. The vulnerability affects all RSA padding
     modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.

eb7d2abbf0 openssl: bump to 1.1.1p
Changes between 1.1.1o and 1.1.1p [21 Jun 2022]

  *) In addition to the c_rehash shell command injection identified in
     CVE-2022-1292, further bugs where the c_rehash script does not
     properly sanitise shell metacharacters to prevent command injection have been
     fixed.

     When the CVE-2022-1292 was fixed it was not discovered that there
     are other places in the script where the file names of certificates
     being hashed were possibly passed to a command executed through the shell.

     This script is distributed by some operating systems in a manner where
     it is automatically executed.  On such operating systems, an attacker
     could execute arbitrary commands with the privileges of the script.

     Use of the c_rehash script is considered obsolete and should be replaced
     by the OpenSSL rehash command line tool.
     (CVE-2022-2068)
     [Daniel Fiala, Tomáš Mráz]

  *) When OpenSSL TLS client is connecting without any supported elliptic
     curves and TLS-1.3 protocol is disabled the connection will no longer fail
     if a ciphersuite that does not use a key exchange based on elliptic
     curves can be negotiated.

0134f845da openssl: configure engines with uci
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.

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.

482c9ff289 openssl: bump to 1.1.1j
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.

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.

450d44a8ea openssl: change defaults: ENGINE:on, NPN:off, misc
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
a small bloat, so it does not make sense to leave it on by default.

Remove deprecated CONFIG_ENGINE_CRYPTO symbol that is no longer needed.
