* [Mellanox]Check dmi file permission before access (#11309)
Signed-off-by: Sudharsan Dhamal Gopalarathnam sudharsand@nvidia.com
Why I did it
During the system boot up when 'show platform status' or 'show version' command is executed before STATE_DB CHASSIS_INFO table is populated, the show will try to fallback to use the platform API. The DMI file in mellanox platforms require root permission for access. So if the show commands are executed as admin or any other user, the following error log will appear in the syslog
Jun 28 17:21:25.612123 sonic ERR show: Fail to decode DMI /sys/firmware/dmi/entries/2-0/raw due to PermissionError(13, 'Permission denied')
How I did it
Check the file permission before accessing it.
How to verify it
Added UT to verify. Manually verified if the error log is not thrown.
- Why I did it
This is for the eventual support of multiple architectures for the mellanox platform.
- How I did it
Change the location of the binaries in Switch-SDK-drivers so that the path specifies the target architecture in addition to the target distribution that the debians are built for.
This is the most straightforward way to separate binaries built against different architectures and selectively target them for installation in the mellanox SONiC image.
- How to verify it
Build SONiC for mellanox and verify it compiles successfully.

1. Warmboot | When trying to reconfigure the Flex Parser header and Flex transition parameters after ISSU, the switch will returned an error even if the configuration was identical to that done before performing the ISSU.
2. Link Up | When toggling many ports of the Spectrum devices while raising 10GbE link up and link maintenance is enabled, the switch may get stuck and may need to be rebooted.
3. Shared buffer | While moving from lossless to lossy while shared headroom was used, reduction of the shared headroom can only be done prior to pool type change and when shared headroom is not utilized.

"import sonic_platform" takes about 600ms ~ 1000ms, it is kind of slow. After this optimization, the time is about 100ms. The benefit is that those CLIs which does not need the slow import sentence would be faster than before.
- How I did it
Find slow import and call them when need.
- How to verify it
Measure the import time.
Currently, the build with ASAN_ENABLE=y reuses the packages built with
ASAN_ENABLE=n (and vice versa). To address this issue, ASAN_ENABLE is added to DEP_FLAGS for asan-enabled packages (docker-syncd-mlnx, syncd, docker-orchagent, swss).
- Why I did it
To make dpkg cache use/rebuild the packages for ASAN_ENABLE=y/n.
- How I did it
Added ASAN_ENABLE to the DEP_FLAGS for asan-enabled packages.
- How to verify it
Built with ASAN_ENABLE=y/n and checked the .flags .log files.
Signed-off-by: Yakiv Huryk <yhuryk@nvidia.com>
This is to improve the readability of ASAN reports. The debug package adds function names and source code references to the backtrace (currently, there are only binary addresses of functions)
Another way to address this issue is to build the image with "INSTALL_DEBUG_TOOLS=y". The downside of this approach is that the image size and compilation time are unnecessarily big. Also, the idea is to make the "ENABLE_ASAN" self-sufficient, which would not be the case for this approach.
- Why I did it
To improve the readability of asan logs.
- How I did it
Added SYNCD_DBG and SWSS_DBG to corresponding docker images for ASAN_ENABLE=y build

Currently, the build dockers are created as a user dockers(docker-base-stretch-<user>, etc) that are
specific to each user. But the sonic dockers (docker-database, docker-swss, etc) are
created with a fixed docker name and common to all the users.
docker-database:latest
docker-swss:latest
When multiple builds are triggered on the same build server that creates parallel building issue because
all the build jobs are trying to create the same docker with latest tag.
This happens only when sonic dockers are built using native host dockerd for sonic docker image creation.
This patch creates all sonic dockers as user sonic dockers and then, while
saving and loading the user sonic dockers, it rename the user sonic
dockers into correct sonic dockers with tag as latest.
docker-database:latest <== SAVE/LOAD ==> docker-database-<user>:tag
The user sonic docker names are derived from 'DOCKER_USERNAME and DOCKER_USERTAG' make env
variable and using Jinja template, it replaces the FROM docker name with correct user sonic docker name for
loading and saving the docker image.

InvalidPsuVolWA.run might raise exception if user power off PSU when it is running. This exception is not caught and will be raised to psud which causes psud failed to update PSU data to DB.
- How I did it
1. Change the log level when WA does not work. This could happen when user power off PSU, hence changing the log level from error to warning is better
2. Change the wait time from 5 to 1 to avoid introduce too much delay in psud. 1 second is usually enough per my test
3. Give a default return value for function get_voltage_low_threshold and get_voltage_high_threshold to avoid exception reach to psud

Take new hw-mgmt release to SONiC, including:
New features:
1. hw-mgmt: add to PSU FW upgrade tool command to show current FW version
2. hw-mgmt: add to PSU FW upgrade tool support for single-PSU-in-the-system FW upgrade
3. hw-mgmt: add attribute “/firmware” to show FW version of restricted upgradable PSUs only
4. hw-mgmt: Add NVME temperature reports attributes (_alarm/_crit/_min/_max)
Bug fix:
1. psu: redundant i2c_addr attributes being created for psu 3 & 4 in system having only 2 psus.
2. hw-mgmt: in SPC1/2 i2c driver removal is too slow vs. ASIC reset causing non-functional log errors
3. PSU thresholds sysfs changed in 5.10 to “read only” preventing modification (modification required due PSU HW bug)
4. CPLD3 sysfs attribute missing after chip down/up flow
5. sysfs attributes missing when hw-mgmt is restarted (stop/start) within systemd

The latest upgrade of Mellanox hw-mgmt V7.0020.1300 introduced a couple new kernel modules for new Mellanox platforms that have yet to be upstreamed to the linux kernel.
As these new platforms do not have SONiC support we elected not to upstream these new drivers to sonic-linux-kernel but hw-mgmt expects them to exist which is causing a non-functional error on switch boot.
Feb 15 00:09:55.374130 r-leopard-simx-74 ERR systemd-modules-load[269]: Failed to find module 'emc2305'
Feb 15 00:09:55.374141 r-leopard-simx-74 ERR systemd-modules-load[269]: Failed to find module 'ads1015'
To resolve this we can patch hw-mgmt to no longer attempt to load these modules by default.
- How I did it
Added a SONiC patch to Mellanox hw-mgmt in order to remove the unused kernel modules which were not upstreamed to sonic-linux-kernel
- How to verify it
Boot switch and verify there are no error logs regarding kernel modules failing to load.
- Why I did it
In SONiC thermal control algorithm, it compares thermal zone temperature with thermal zone threshold. Previously, a thermal zone with no thermal sensor can still get its threshold. However, a recently driver patch changes this behavior: a thermal zone with no thermal sensor will return 0 for threshold. We need to ignore such thermal zone.

Ignore thermal zones whose temperature is 0.

Requirements from Microsoft for fwutil update all state that all firmwares which support this upgrade flow must support upgrade within a single boot cycle. This conflicted with a number of Mellanox upgrade flows which have been revised to safely meet this requirement.
How I did it
Added --no-power-cycle flags to SSD and ONIE firmware scripts
Modified Platform API to call firmware upgrade flows with this new flag during fwutil update all
Added a script to our reboot plugin to handle installing firmwares in the correct order with prior to reboot
How to verify it

Execute fwutil update all fw --boot cold
CPLD will burn / ONIE and BIOS images will stage / SSD will schedule for reboot
Reboot the switch
SSD will install / CPLD will refresh / switch will power cycle into ONIE
ONIE installer will upgrade ONIE and BIOS / switch will reboot back into SONiC
In SONiC run fwutil show status to check that all firmware upgrades were successful
