typo in ipmctl command invocation produces segmentation fault

[Mark-Baker]

This demonstrates with both 3797 and 3809 (I didn't test earlier versions against this issue)

Thanks for letting us know. We will look into it.

What was the command that was ran? It looks like a form of show -error.

What type of system was this seen on?

I confirmed the issue is reproducible on ipmctl 02.00.00.3781.

Working:

# ipmctl show -error Thermal
No errors found on PMem module 0x0001
No errors found on PMem module 0x0011
No errors found on PMem module 0x0021
No errors found on PMem module 0x0101
No errors found on PMem module 0x0111
No errors found on PMem module 0x0121
No errors found on PMem module 0x1001
No errors found on PMem module 0x1011
No errors found on PMem module 0x1021
No errors found on PMem module 0x1101
No errors found on PMem module 0x1111
No errors found on PMem module 0x1121
Show Error executed successfully

Not working (Note the the extra 's', although any spelling error causes the core dump)

# ipmctl show -error Thermals
NVM_DBG_LOGGER NVDIMM-ERR:ShowErrorCommand.c::ShowErrorCommand:719: Failed to buffer a command status object! (0x2)

Segmentation fault (core dumped)

# ipmctl show -error Medias
NVM_DBG_LOGGER NVDIMM-ERR:ShowErrorCommand.c::ShowErrorCommand:719: Failed to buffer a command status object! (0x2)

Segmentation fault (core dumped)

dmesg reports the following for each core dump

I didn't try all the commands and options, but other show commands return an expected error when we have a typo, eg:

# ipmctl show -pcd Configy
Syntax Error: Incorrect value for target -pcd.

ipmctl show -pcd Config works as expected.
