Set sysctl fs.suid_dumpable = 2
This allows suid processes to dump core according to kernel.core_pattern
setting. LEDE typically uses suid to drop root priviledge rather than
gain it but without this setting any suid process would be unable to
produce coredumps (e.g. dnsmasq)
Processes still need to set a non zero core file process limit ('ulimit
-c unlimited' or if procd used 'procd_set_param limits
core="unlimited"') in order to produce a core. This setting removes an
obscure stumbling block along the way.
>From https://www.kernel.org/doc/Documentation/sysctl/fs.txt
suid_dumpable:
This value can be used to query and set the core dump mode for setuid
or otherwise protected/tainted binaries. The modes are
0 - (default) - traditional behaviour. Any process which has changed
privilege levels or is execute only will not be dumped.
1 - (debug) - all processes dump core when possible. The core dump is
owned by the current user and no security is applied. This is
intended for system debugging situations only. Ptrace is unchecked.
This is insecure as it allows regular users to examine the memory
contents of privileged processes.
2 - (suidsafe) - any binary which normally would not be dumped is dumped
anyway, but only if the "core_pattern" kernel sysctl is set to
either a pipe handler or a fully qualified path. (For more details
on this limitation, see CVE-2006-2451.) This mode is appropriate
when administrators are attempting to debug problems in a normal
environment, and either have a core dump pipe handler that knows
to treat privileged core dumps with care, or specific directory
defined for catching core dumps. If a core dump happens without
a pipe handler or fully qualifid path, a message will be emitted
to syslog warning about the lack of a correct setting.

The ZBT WE1026-5G
(http://www.zbtlink.com/products/router/WE1026-5G.html) is the follow-up
to the ZBT WE1026 and is based on MT7620. For the previous WE1026, the
ZBT WE826 image could be used. However, as the name implies, the -5G
comes equipped with a 5GHz wifi radio. As the WE826 only has a 2.4GHz
radio, the addition of 5GHz means that a separate image is needed for
the WE1026-5G. I suspect that this image will also work on the previous
WE1026, but I don't have a device to test with.
The WE1026-5G has following specifications:
* CPU: MT7620A
* 1x 10/100Mbps Ethernet.
* 16 MB Flash.
* 64 MB RAM.
* 1x USB 2.0 port.
* 1x mini-PCIe slots.
* 1x SIM slots.
* 1x 2.4Ghz WIFI.
* 1x 5GHz wifi (MT7612)
* 1x button.
* 3x controllable LEDs.
Works:
* Wifi.
* Switch.
* mini-PCIe slot. Only tested with a USB device (a modem).
* SIM slot.
* Sysupgrade.
* Button (reset).
Not working:
* The 5GHz WIFI LED is completely dead. I suspect the issue is the same
as on other devices with Mediatek 5Ghz wifi-cards/chips. The LED is
controlled by the driver, and mt76 (currently) does not support this.
Not tested:
* SD card reader.
Notes:
* The modem (labeled 3G/4G) and power LEDs are controlled by the
hardware.
* There is a 32MB version of this device available, but I do not have
access to it. I have therefor only added support for the 16MB version,
but added all the required infrastructure to make adding support for the
32MB version easy.
Installation:
The router comes pre-installed with OpenWRT, including a variant of
Luci. The initial firmware install can be done through this UI,
following normal procedure. I.e., access the UI and update the firmware
using the sysupgrade-image. Remember to select that you do not want to
keep existing settings.
Recovery:
If you brick the device, the WE1026-5G supports recovery using HTTP. Keep the
reset button pressed for ~5sec when booting to start the web server. Set the
address of the network interface on your machine to 192.168.1.2/24, and
point your browser to 192.168.1.1 to access the recovery UI. From the
recovery UI you can upload a firmware image.

Currently, if the provided hash is unsupported (length different from 32
or 64 bytes), we happily download the requested file without any kind of
checksum verification.
This is quite dangerous and may provide a false sense of security, because
a single typo in the hash (e.g. one character deleted by mistake) may skip
checksum verification entirely.
Instead, fail immediately if we don't support the provided hash.
In particular, if an external package repository decides to change the
hash algorithm one day, we will now fail loudly instead of skipping
checksum verification without complaints.
Note: if some users of scripts/download.pl knowingly provide an empty hash
because they don't need checksum verification, this change will break
them. This does not seem to be the case currently, but if this feature is
ever needed, an option should be added to download.pl instead of relying
on the hash being empty.

The cns3xxx interrupt controller uses a single register and as such

Fixed an authentication bypass issue in SSL/TLS. When the TLS
authentication mode was set to 'optional',
mbedtls_ssl_get_verify_result() would incorrectly return 0 when the
peer's X.509 certificate chain had more than
MBEDTLS_X509_MAX_INTERMEDIATE_CA intermediates (default: 8), even when
it was not trusted. This could be triggered remotely on both the client
and server side. (Note, with the authentication mode set by
mbedtls_ssl_conf_authmode()to be 'required' (the default), the handshake
was correctly aborted).

For the Archer C50v1, the EU and US versions are differentiated by their
respective HW additional version (0x0 for US, 0x2 for EU).
The stock web interface checks this field before flashing, making it
impossible to flash the current (US) factory image on EU hardware.
However the bootloader does not check this field, making it possible to use
a single sysupgrade image for both hardware.
This patch adds the necessary build bits to generate both EU and US factory
images, and renames the target as "Archer C50v1" since there are as of now
3 different versions of Archer C50 (all with different CPUs).

* Button (reset).
Not working (also applies to the factory firmware):
* Wifi LED. It is always switched on, there is no relation to the
up/down state or activity of the wireless interface.
Not tested:
* SD card reader.
Notes:
* The C108 has no dedicated status LED. I therefore set the LAN LED as
status LED.

In conditions where none of the switch ports is connected during boot,
the priv->port[i].link != priv->port[i].phydev->link condition is false
since both link values are equal (false). The carrier of the switch
netdev is never set to off and the link state reported by ip is UNKNOWN.
Turn the carrier off if none of the switch ports has a link, regardless
whether something has been changed. Add a check for a carrier to
prevent unnecessary calls to netif_carrier_off() if the carrier is
already off.

Extendprefix is typically used to extend an IPv6 RA prefix from a mobile
