This fixes regressed support for Tenda AC9 which got broken somewhere
between LEDE 17.01 and OpenWrt 18.06.
At some point bcm47xx_nvram_gpio_pin() started working on bcm53xx
devices and it resulted in swconfig b53 performing GPIO-based switch
reset. It exposed some bug as switch stopped working.
The problem is most likely to be some missing initialization step. Tenda
AC9 comes with BCM53125 rev 4 (pretty common chip) but apparently needs
some extra quirk.
As a workaround (it doesn't make much sense to debug swconfig driver
which has a working DSA replacement) simply avoid full switch reset.
So far every build of a single bcm53xx Target Profile (it means: when
NOT using CONFIG_TARGET_MULTI_PROFILE) resulted in all target devices
images being built. Now it only builds the one matching selected
profile.

What's interesting about jitterentropy-rngd v1.2.0 release is that it
bumps its copy of jitterentropy-library from v2.2.0 to the v3.0.0. That
bump includes a relevant commit 3130cd9 ("replace LSFR with SHA-3 256").
When initializing entropy jent calculates time delta. Time values are
obtained using clock_gettime() + CLOCK_REALTIME. There is no guarantee
from CLOCK_REALTIME of unique values and slow devices often return
duplicated ones.
A switch from jent_lfsr_time() to jent_hash_time() resulted in many less
cases of zero delta and avoids ECOARSETIME.
Long story short: on some system this fixes:

bcm53xx: add BCM53573 Ethernet fix sent upstream for v6.6
It seems that DSA-based b53 driver never worked with BCM53573 SoCs and
BCM53125.
In case of swconfig-based b53 this fixes a regression. Switching bgmac
from using mdiobus_register() to of_mdiobus_register() resulted in MDIO
device (BCM53125) having of_node set (see of_mdiobus_register_phy()).
That made downstream b53 driver read invalid data from DT and broke
Ethernet support.
Some device recipes remove default target packages. If user tries to add
them back they will be ignored, since packages list is processed in one
go. Process the device recipe packages first and do user ones later, so
additions won't get filtered out.
The DGND3700v2 renames the cferam bootloader from cferam to cfeXXX, where XXX
is the number of firmware upgrades performed by the bootloader. Other bcm63xx
devices rename cferam.000 to cferam.XXX, but this device is special because
the cferam name isn't changed on the first firmware flashing but it's changed
on the subsequent ones.
Therefore, we need to look for "cfe" instead of "cferam" to properly detect
the cferam partition and fix the bootlop.
Some devices rename cferam bootloader using specific patterns and don't follow
broadcom standards for renaming cferam files. This requires supporting
different cferam file names.
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: bump to 1.1.1t
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.

mpc85xx: Drop pci aliases to avoid domain changes
As of upstream Linux commit 0fe1e96fef0a ("powerpc/pci: Prefer PCI
domain assignment via DT 'linux,pci-domain' and alias"), the PCIe
domain address is no longer numbered by the lowest 16 bits of the PCI
register address after a fallthrough. Instead of the fallthrough, the
enumeration process accepts the alias ID (as determined by
`of_alias_scan()`). This causes e.g.:
... which then causes the sysfs path of the netdev to change,
invalidating the `wifi_device.path`s enumerated in

One other solution might be to migrate the uci configuration, as was

Package with whitespace in their build directory are not correctly
removed when CONFIG_AUTOREMOVE is enabled. This is caused by xargs that
use whitespace as delimiters. To handle this use \0 as the delimiter and
set find to use \0 as the delimiter.
