[device/celestica] Mitigation for command injection vulnerability (#11740)
Signed-off-by: maipbui <maibui@microsoft.com>
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()

Fix issue of partially parsing syseeprom value (#10020) (#10276)
Why I did it
The current code assumes that the value part does not have whitespace. So everything after the whitespace will be ignored. The syseeprom values returned from platform API do not match the output of "show platform syseeprom" on dx010 and e1031 device.

How I did it
This change improved the regular expression for parsing syseeprom values to accommodate whitespaces in the value.
PR 10021 provides the solution, but committed to the wrong place for dx010 and e1031.

How to verify it
Compile the sonic_platform wheel for dx010, then upload to device and install the wheel, verify the platform eeprom API.

Add platform_asic file to each platform folder in sonic-device-data based package (#8542)
#### Why I did it
Add platform_asic file to each platform folder in sonic-device-data package. The file content will be used as the ground truth of mapping from PLATFORM_STRING to switch ASIC family.

One use case of the mapping is to prevent installing a wrong image, which targets for other ASIC platforms. For example, currently we have several ONIE images naming as sonic-*.bin, it's easy to mistakenly install the wrong image. With this mapping built into image, we could fetch the ONIE platform string, and figure out which ASIC it is using, and check we are installing the correct image.

After this PR merged, each platform vendor has to add one mandatory text file  `device/PLATFORM_VENDOR/PLATFORM_STRING/platform_asic`, with the content of the platform's switch ASIC family.

I will update https://github.com/Azure/SONiC/wiki/Porting-Guide after this PR is merged.

You can get a list of the ASIC platforms by `ls -b platform | cat`. Currently the options are
```
barefoot
broadcom
cavium
centec
centec-arm64
generic
innovium
marvell
marvell-arm64
marvell-armhf
mellanox
nephos
p4
vs
```

Also support
```
broadcom-dnx
```

#### How I did it

#### How to verify it
Test one image on DUT. And check the folders under `/usr/share/sonic/device`

SONIC QOS YANG - Remove qos tables field value refernce format (#7752)
Depends on Azure/sonic-utilities#1626
Depends on Azure/sonic-swss#1754

QOS tables in config db used ABNF format i.e "[TABLE_NAME|name] to refer fieldvalue to other qos tables.

Example:
Config DB:
"Ethernet92|3": {
"scheduler": "[SCHEDULER|scheduler.1]",
"wred_profile": "[WRED_PROFILE|AZURE_LOSSLESS]"
},
"Ethernet0|0": {
"profile": "[BUFFER_PROFILE|ingress_lossy_profile]"
},
"Ethernet0": {
"dscp_to_tc_map": "[DSCP_TO_TC_MAP|AZURE]",
"pfc_enable": "3,4",
"pfc_to_queue_map": "[MAP_PFC_PRIORITY_TO_QUEUE|AZURE]",
"tc_to_pg_map": "[TC_TO_PRIORITY_GROUP_MAP|AZURE]",
"tc_to_queue_map": "[TC_TO_QUEUE_MAP|AZURE]"
},

This format is not consistent with other DB schema followed in sonic.
And also this reference in DB is not required, This is taken care by YANG "leafref".

Removed this format from all platform files to consistent with other sonic db schema.
Example:
"Ethernet92|3": {
"scheduler": "scheduler.1",
"wred_profile": "AZURE_LOSSLESS"
},

[cel seastone 2] Add 10G SFP1 front port (#8267)
Why I did it
The SFP1 port was disabled in the default configuration.

How I did it
This commit enables the 10G front port for usage.
This was done using a DX030 together with an Arista switch using bcmsh and phy diag xe0 dsc to figure out what lane mappings make sense.

Validated on Celestica Seastone2 DX030.

How to verify it
Own a Celestica DX030
Connect the front SFP1 port to something.
It works :-)
You can do tcpdump -i Ethernet128 -n and you will see both incoming and outgoing LLDP.

To fix [DPB| wrong aliases for interfaces](https://github.com/Azure/sonic-buildimage/issues/6024) issue, implimented flexible alias support [design doc](https://github.com/Azure/SONiC/pull/749)

> [[dpb|config] Fix the validation logic of breakout mode](https://github.com/Azure/sonic-utilities/pull/1440) depends on this

#### How I did it

1. Removed `"alias_at_lanes"` from port-configuration file(i.e. platfrom.json) 
2. Added dictionary to "breakout_modes" values. This defines the breakout modes available on the platform for this parent port, and it maps to the alias list. The alias list presents the alias names for individual ports in order under this breakout mode.

[Celestica] Ensure concrete platform API classes call base class initializer (#6852)
In preparation for the merging of Azure/sonic-platform-common#173, which properly defines class and instance members in the Platform API base classes.

It is proper object-oriented methodology to call the base class initializer, even if it is only the default initializer. This also future-proofs the potential addition of custom initializers in the base classes down the road.

[platform] Update QSFP method name 'parse_qsfp_dom_capability' -> 'parse_dom_capability' (#6695)
**- Why I did it**
PR https://github.com/Azure/sonic-platform-common/pull/102 modified the name of the SFF-8436 (QSFP) method to align the method name between all drivers, renaming it from `parse_qsfp_dom_capability` to `parse_dom_capability`. Once the submodule was updated, the callers using the old nomenclature broke. This PR updates all callers to use the new naming convention.

**- How I did it**

Update the name of the function globally for all calls into the SFF-8436 driver.

Note that the QSFP-DD driver still uses the old nomenclature and should be modified similarly. I will open a PR to handle this separately.

[broadcom]: Add BCM config variable that contains premier cancun firmware path (#6611)
BRCM SDK 6.5.21 includes firmware updates (premier cancun) for TD3 platforms. The firmware update is required on TD3 platforms, which is packaged with BCMSAI 4.3.0.10.

**- How I did it**

Updated BCM config with a new variable that specifies the firmware package path. SDK uses this path to locate firmware packages and load during cold boot.

**- How to verify it**

[device/celestica]: Add thermalctld support on DX010 platform APIs (#6089)
**- Why I did it**
- The thermalctld daemon on the Pmon docker requires support from the thermal manager API.

**- How I did it**
- Removed the old function for detecting a faulty fan.
- Removed the old function for detecting excess temperature.
- Implement thermal_manager APIs based on ThermalManagerBase
- Implement thermal_conditions APIs based on ThermalPolicyConditionBase
- Implement thermal_actions APIs based on ThermalPolicyActionBase
- Implement thermal_info APIs based on ThermalPolicyInfoBase
- Add thermal_policy.json

[celestica/dx010]: Fix incorrect path for voltage, current and power. (#6128)
Fixes #6126.

There is a bug in getting the path of voltage, current and power. The
list object is directly converted to string to format the file path. As
a result, read_txt_file will get None value and a WARNING will be
recorded. This commit fix the issue.
