Hi Eric and Saul,
My patch has already been accepted by upstream and merged. https://github.com/DMTF/Redfishtool/pull/67 So, I believe we can remove this patch soon.
Thanks! Zhipeng

Saul,
Very good points and suggestion. Thank you.
Zhipeng,
Can you put this out to the general starling-x discussion list as well as Redfish discussion list and keep us informed as to how the redfish community is reacting to the change request.
Eric.

Hi Zihipeng, Eric:
I would like to see this move to the general discuss list, I think it's appropriate for everyone to understand what's going. Thanks for getting the patch proposed to upstream Redfish.
I am concerned first with the technical debt and making sure that the Redfish upstream community is aware of what we are proposing / doing in StarlingX. I had another look at this and I now have a better idea of why it kept being a concern.
1) processing the config file itself inside of options processing is not generally a good idea. It does not allow for easy parsing and extension of the config file's contents.
2) I see you using json, this is good, thanks for proposing it to the Redfish community, they might have an idea to use a different format for the contents of the config file. This gets the json idea out there now rather than finding out in 6 month they they decided to use a different format.
3) As I have mentioned before having plain text passwords is never my favorite way to go, but since we are already down that path with IPMI, let's keep going, again maybe the RedFish community had thought about this or this patch proposal will force that discussion.
My sunday afternoon thoughts.
Sau!

Hi Eric,
Thanks for your clarification!
BTW, how to use process listing, could you give me an example? J

Hi Zhipeng,
See below.
Is Saul’s concern the technical debt of the config patch or the pw file in general. Seems the former.
What can do, should I speak with him ?
Eric.

Hi Eric,
For configfile patch, Saul still have some concern about it and why we use a password file
Anyway, I have submitted patch to upstream.
https://github.com/DMTF/Redfishtool/pull/67
From code, I can see that MTC get bmc_pw through keyring.
*/[... Eric ] or barbican now, yes./*
Then we pass the bmc_pw through extra_info to ipmi command thread
*/[... Eric ] Yes/*
“The current implementation using IPMITOOL puts the BMC password into a short lived root privilege temp file so that it does not show up in a process listing.”
Why we have to use temp file instead of showing up in a process listing? The password can be got through process listing? Not clear about this point.
*/[... Eric ] If we use the –P <pw> option when invoking ipmitool then while that command is active and someone does a process listing then they can see the –P <pw> on the process listing. This is a security issue because a non-root user can learn the BMC password for any host by just doing a process listing on the active controller./*
Could you give me more detail information, thanks!
From below code, it seems we have comment related code. Does it means the file may not be removed right away even with the file open.
So, still not sure which one is much more safe.
*/[... Eric ] The temp file is removed in the thread after execution completion or timeout./*
*/Example code taken from mtcThreads.cpp/*
*//*
*//*
*/There is also a garbage collection cleanup audit that ensures these temp files do not linger due to ‘say’ a process restart during command execution./*
*/[... Eric ] /**//*
*//*
*
* TODO: fix or figure out why the unlink removes the file right away even
* with the file open.
*
******************************************************************** *********/
*/[... Eric ] The above comment was added simply because when I was coding I didn’t understand why the unlink removes the file right away./*
*/I think now that it was because the file was not open at the time the unlink was executed./*
*//*
*/In any case the tmp pw file is still removed with redundancy./*
int hostUtil_mktmpfile ( string hostname, string basename, string & filename, string data )
{
// buffer to hold the temporary file name
char tempBuff[MAX_FILENAME_LEN];
int fd = -1;
memset(tempBuff,0,sizeof(tempBuff));
if ( basename.empty() || data.empty() )
{
slog ("%s called with one or more bad parameters (%d:%d)\n",
hostname.c_str(), basename.empty(), data.empty());
return (0);
}
/* add what mkstemp will make unique */
basename.append("XXXXXX");
// Copy the relevant information in the buffers
snprintf ( &tempBuff[0], MAX_FILENAME_LEN, "%s", basename.data());
// Create the temporary file, this function will
// replace the 'X's with random letters
fd = mkstemp(tempBuff);
// Call unlink so that whenever the file is closed or the program exits
// the temporary file is deleted.
//
// Note: Unlinking removes the file immediately.
// Commenting out. Caller must remove file.
//
// unlink(tempBuff);
Thanks!

Hi Zhipeng,
I've been upgrading the firmware on our set of WolfPass servers.
Even with the upgrade I’ve been having a hard time reading ther server sensors through redfish.
Can you send me the command(s) you use and output you see for/when dumping the sensors on your WolfPass server ?
I use the following commands on the supermicro but it seems that the wolfpass servers don't support this method.
redfishtool -r <BMC IP> -u <bmc username> -p <bmc password> Chassis Thermal
redfishtool -r <BMC IP> -u <bmc username> -p <bmc password> Chassis Power
Here are the firmware versions I have. I wonder if it’s my SDR version. What is yours ?
