Why I did it
Current isc-dhcp uses below code to remove DHCP option:
memmove(sp, op, op[1] + 2);
sp += op[1] + 2;
sp points to the option to be stripped, we can call it as option S.
op points to the option after options S, we can call it as option O.
DHCP option is a typical type-length-value structure, the first byte is type, the second byte is length, and remain parts are value.
In this case, option O length is bigger than option S, and more than 2 bytes, after the memmove, we will get this result:
Now Option S and Option O are overwritten, op[1] was the length of Option O, and it's modified after memmove.
But current implementation is still using op[1] as length to update sp (sp+=op[1]+2), so we get the wrong sp.
How I did it
Create patch from https://github.com/isc-projects/dhcp
The new impelementation use mlen to store the length of Option O before memmove, that's how it fixed the bug.
size_t mlen = op[1] + 2;
memmove(sp, op, mlen);
sp += mlen;

Why I did it
This PR is to update TC_TO_QUEUE_MAP|AZURE for SKU Arista-7050CX3-32S-D48C8 and Arista-7260CX3 T0.
The change is only to align the TC_TO_QUEUE_MAP for regular traffic and bounced traffic. It has no impact on business because we have no traffic being mapped to TC2 or TC6.
How I did it
Update TC_TO_QUEUE_MAP|AZURE , and test cases as well.
How to verify it
Verified by running test case test_j2files.py
/sonic/src/sonic-config-engine$ python3 setup.py test -s tests/test_j2files.py
running test

It is caused by the login message mixed with the output message of the /etc/rc.local, one of the examples as below: (see the message rc.local[307]: sonic+ onie_disco_subnet=255.255.255.0 login: )
The check_install.py was waiting for the message "sonic login:", and Linux console was waiting for the username input (the login message has already printed in the console).

Approve step needs special permission settings.
We already added permission setting to enable bypass merging PR.
So, approve step is not necessary.
For the Restapi/gnmi use-cases, Sonic has to support a new Table: EXTERNAL_CLIENT of type CTRLPLANE, stage ingress
This shall match on 'src ip prefix' and dst port '8080'. Caclmgrd must parse this from acl.json and install as in the below example:
iptables -A INPUT -s 20.20.20.20/27 -p tcp --dport 8080 -j ACCEPT
or ip6tables if the 'src ip prefix' is IPv6.
