#### Why I did it
When a kernel crash occurs, the system will reboot to the kdump capture kernel if kdump is enabled (`config kdump enable`). In the kdump capture boot, it only stores the crash information, and then reboot the system to a normal boot.
In this boot, no SONiC service is started but it invokes `reboot` which is actually the SONiC reboot that depends on SONiC services. There is a logic to skip all SONiC stuff and invoke platform reboot in SONiC reboot to avoid issues.
However, on Nvidia platforms, the platform reboot still depends on SONiC services, which can cause issues.
So, the Debian reboot is called directly in platform reboot if it is invoked from the kdump capture boot.

- How I did it
Regarding buffer settings, originally, there are two lossless PGs and queues 3, 4. In dual ToR scenario, the lossless traffic from the leaf switch to the uplink of the ToR switch can be bounced back.
To avoid PFC deadlock, we need to map the bounce-back lossless traffic to different PGs and queues. Therefore, 2 additional lossless PGs and queues are allocated on uplink ports on ToR switches.
On uplink ports, map DSCP 2/6 to TC 2/6 respectively
On downlink ports, both DSCP 2/6 are still mapped to TC 1
Buffer adjusted according to the ports information:
Mellanox-SN4600c-C64:
56 downlinks 50G + 8 uplinks 100G
Mellanox-SN4600c-D48C40, Mellanox-SN2700, Mellanox-SN2700-D48C8:

This is to fix test_forward_ip_packet_with_0xffff_chksum_tolerant test failure on 720DT-48S. IP packets with checksum set to 0xffff will be forwarded with the same checksum on this platform, instead of updating to the correct value.
How I did it
Add bcm config sai_verify_incoming_chksum=0 so that checksum is updated instead of being left unchanged when checksum is 0xffff. Note that packets with invalid checksum are still dropped with this config.
Why I did it
On DNX (J2/J2c/J2c+) platforms, Single Path Nexthops and ECMp Nexthop resources(FECs) are shared. BRCM SAI do not have partition of this resource, and hence more single path Nexthop entries, causes ECMP programming to fail in scaled setup.
How I did it
Broadcom provided SAI changes to reserve resources for single path nexthop entries(More details in CSP: https://brcmsemiconductor-csm.wolkenservicedesk.com/wolken-support/allcases/request-details?requestId=CS00012251649).
Along with SAI changes, they provided configurable Macro/flag to reserve NON_ECMP entries.
This PR is to add that flag in various sai.profile files wherever applicable.
PS: We are reserving 3072 single path Nexthop entries on each Linecard. Calculation is as follows.
Max Slots per chassis: 8
Max No of Ports(each LC): 64
MyIP/Subnet Entries per port: 4(v4/v6)
Nbr Entries Per port: 2(v4/v6)
Total Non_ECMP Count: 8x64x(4+2) = 3072
How to verify it
Without this change, the ECMP group count will be shown as Max_count in 'crm show resources all' command, and with this change the ECMP group count will be decreased by 24(3072/128).
Port indexes of front panel ports are not contiguous in multi-asic because we didn't distiguish between

Dependency: [PR (#12065)](https://github.com/sonic-net/sonic-buildimage/pull/12065) needs to merge first.
#### Why I did it
1. `eval()` - not secure against maliciously constructed input, can be dangerous if used to evaluate dynamic content. This may be a code injection vulnerability.
2. `subprocess()` - when using with `shell=True` is dangerous. Using subprocess function without a static string can lead to command injection.
3. `os` - not secure against maliciously constructed input and dangerous if used to evaluate dynamic content.
4. `is` operator - string comparison should not be used with reference equality.
5. `globals()` - extremely dangerous because it may allow an attacker to execute arbitrary code on the system
#### How I did it
1. `eval()` - use `literal_eval()`
2. `subprocess()` - use `shell=False` instead. use an array string. Ref: [https://semgrep.dev/docs/cheat-sheets/python-command-injection/#mitigation](https://semgrep.dev/docs/cheat-sheets/python-command-injection/#mitigation)
3. `os` - use with `subprocess`
4. `is` - replace by `==` operator for value equality
5. `globals()` - avoid the use of globals()
This change is to disable the pcie firmware check done by Broadcom SAI. The change is needed for the Arista platform x86_64-arista_7050cx3_32s; otherwise, the check will fail, blocking the initialization.
There was a pcie firmware check added in brcm SDK and certain Arista hardwares do not compliant with the check, so we added the disable_pcie_firmware_check originally for x86_64-arista_7060dx4_32. For x86_64-arista_7050cx3_32s, it was able to pass the check but some firmware change done in August made it fail.
Why I did it:
Fix multiple seastone platform issues caused by sonic kernel upgrade.
How I did it:
Get gpio base id with new label path in gpio sys fs.
How to verify it:
After the change, show platform fan/psustatus/temperature works well.

#### Why I did it
`subprocess.Popen()` and `subprocess.run()` is used with `shell=True`, which is very dangerous for shell injection.
`os` - not secure against maliciously constructed input and dangerous if used to evaluate dynamic content
`getstatusoutput` is dangerous because it contains `shell=True` in the implementation
#### How I did it
Replace `os` by `subprocess`, use with `shell=False`
Remove unused functions
#### Why I did it
`os` and `commands` modules are not secure against maliciously constructed input
`getstatusoutput` is detected without a static string, uses `shell=True`
#### How I did it
Eliminate the use of `os` and `commands`
Use `subprocess` instead

Why I did it
ECN parameters need to be updated for storage backend
How I did it
Included the check for storage backend devices to update qos configs
How to verify it
Verified that the new ecn settings are applied on storage backend device.
Verified that the old ecn settings are applied for storage frontend, non storage frontend/backend devices

#### Why I did it
The [xml.etree.ElementTree](https://docs.python.org/3/library/xml.etree.elementtree.html#module-xml.etree.ElementTree) module is not secure against maliciously constructed data.
`os` - not secure against maliciously constructed input and dangerous if used to evaluate dynamic content
`subprocess.getstatusoutput` is dangerous because include shell=True in the implementation
#### How I did it
Remove xml. Use [lxml](https://pypi.org/project/lxml/) XML parsers package that prevent potentially malicious operation.
Replace `os` by `subprocess`
Use command as an array instead of string
Use `getstatusoutput_noshell` in `sonic_py_common` lib
Why I did it
Added to allow test_crm_route to pass; the test tries to add a /126 ipv6 route and this change is required in order for the count of available routes to be updated correctly.
Why I did it
TX FIR tuning should be done based on the type of inserted transceiver
How I did it
Add media_settings.json which contains the tuning data for 100G optic and 400G optic.
How to verify it
Tested against x86_64-arista_7800r3a_36d2_lc
Why I did it
The PR is to apply separated DSCP_TO_TC_MAP and TC_TO_QUEUE_MAP to uplink ports on dualtor.
The traffic with DSCP 2 and DSCP 6 from T1 is treated as lossless traffic.
DSCP TC Queue
2 2 2
6 6 6
Traffic with DSCP 2 or DSCP 6 from downlink is still treated as lossy traffic as before.
How I did it
Define DSCP_TO_TC_MAP|AZURE_UPLINK and TC_TO_QUEUE_MAP|AZURE_UPLINK.
How to verify it
Verified by UT
Verified by coping the new template to a testbed, and rendering a config_db.json
Why I did it
Some sonic-mgmt platform_tests/api were failing on the 7060CX-32S
How I did it
Added the missing metadata in platform.json and platform_components.json
This is purely test data and does not impact our API implementation.
How to verify it
Run platform_tests / api and expect 100% pass rate.
