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;

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

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.

After pinging any failed IPv6 neighbor entries, set the remaining failed/incomplete entries to a permanent INCOMPLETE state. This manual setting to INCOMPLETE prevents these entries from automatically transitioning to FAILED state, and since they are now incomplete any subsequent NA messages for these neighbors is able to resolve the entry in the cache.

The initial value has to be present for the state machines to work. In active-standby dual-tor scenario, or any hardware mux scenario, the value will be updtaed eventually with a delay.
However, in active-active dual-tor scenario, there is no other mechanism to initialize the value and get state machines started.
So this script will have to write something at start up time.
For active-active dualtor, 'active' is a more preferred initial value, the state machine will switch the state to standby soon if
link prober found link not in good state.
How I did it
Update the script to always provide initial values.
How to verify it
Tested on active-active dual-tor testbed.

Avoid write_standby in warm restart context.

Why I did it
In warm restart context, we should avoid mux state change.
How I did it
Check warm restart flag before applying changes to app db.
How to verify it
Ran write_standby in table missing, key missing, field missing scenarios.
Did a warm restart, app db changes were skipped. Saw this in syslog:
WARNING write_standby: Taking no action due to ongoing warmrestart.
Why I did it
After PFC interop testing between 8102 and 7050cx3, data packet losses were observed on the Rx ports of the 7050cx3 (inflow from 8102) during testing. This was primarily due to the slower response times to react to PFC pause packets for the 8102, when receiving such frames from neighboring devices. To solve for the packet drops, the 7050cx3 pg headroom size has to be increased to 160kB.
How I did it
Modified the xoff threshold value to 160kB in the pg_profile file to allow for the buffer manager to read that value when building the image, and configuring the device
How to verify it
run "mmuconfig -l" once image is built
