** Description changed: [IMPACT] sosreport networking plugin unconditionally exercise 'ethtool -e'. EEPROM dump collection might hang on specific types of devices, ETHTOOL(8) -e --eeprom-dump Retrieves and prints an EEPROM dump for the specified network device. When raw is enabled, then it dumps the raw EEPROM data to stdout. The length and offset parameters allow dumping certain portions of the EEPROM. Default is to dump the entire EEPROM. [TEST PLAN] * On a xenial system ## Should not execute 'ethtool -e' (Default behaviour) * sosreport -o networking ## Should execute 'ethtool -e'. (Only if sosreport is instructed to do so) * sosreport -o networking --plugin-option networking.eepromdump + + ## Should not execute 'ethtool -e' with -a (if with appropriate tunables in /etc/sos.conf) + --- + [tunables] + networking.eepromdump = off + --- + + ## Should execute 'ethtool -e' with -a (if without appropriate tunables + in /etc/sos.conf) [WHERE PROBLEM OCCURS] No problem expected. networking plugin will be gated to prevent 'ethtool -e' to be run by default, so that 'sosreport -o networking' will now no longer execute 'ethtool -e' command. On the other end, if one really want to eepromdump, one can use the 'eepromdump' plugin option as follows: sosreport -o networking --plugin-option networking.eepromdump Yes, we are changing the default behaviour for good reasons as it may produce more harm than good the way it is at the moment, BUT the former behaviour is still available if *REALLY* needed, and after knowing the risk that this could occur. Note: sosreport -a ## Will still execute 'ethtool -e' as it turns all options to 'True'. -a, --alloptions Set all boolean options to True for all enabled plug-ins. Unless one specify the following in /etc/sos.conf: --- [tunables] networking.eepromdump = off --- so 'sosreport -a' with a combination of adding the right tunables in /etc/sos.conf will prevent 'ethtool_e' to be executed.
