Project Description: This fast-track proposes to extend the behavior of vuprintf() and uprintf() routines to log message to user tty and global zones's syslog and also to non-global zone's syslog. Currently these routines log message to user tty and global zones's syslog. 2.2. Risks and Assumptions: There are no risks and assumptions. 4. Technical Description: 4.1. Details: When the user process gets killed due to hardware uncorrectable error we would like to log the message on user tty. The kernel has a uprintf() routine which outputs the message to user tty and in addition logs it into syslog. But when process gets killed in non-global zone due to uncorrectable error, the uprintf() sends the message to user tty and to global's zone's syslog, but not to the non-global zone's syslog. And currently there is no printf in kernel to log message to non-global zone's syslog. Therefore we propose modification to behavior of uprintf() and vuprintf() routines to log message to both global and non-global zone's syslog and as well to log the message on user tty. 4.2. Bug/RFE Number(s): 6676374 If Solaris Kills a process, the user needs to know why 4.5. Interfaces: The interfaces change here is behaviour change of the routines uprintf() and vuprintf(), to log message to global zone's syslog and to user tty and as well to non-global zone's syslog. We do not plan to change the current stability level for uprintf() and vuprintf() routines. Note: uprintf() was declared Contract Private in PSARC/2001/599. As this is now an obsolete term the interface classification is Contracted Consolidation Private. The SAM-QFS teams (Development and Sustaining) will be notified of the change in behavior the functions. 5. Reference Documents: 6676374 If Solaris Kills a process, the user needs to know why 6.

I suggested that the team go for ARC review (FastTrack, of course) because they were changing the behavior of an interface that was at least Consolidation Private. I speculated that the zones folks just overlooked uprintf() and vuprintf() when they added zprintf(), vzprintf(), anc zcmn_err() (there is no zuprintf() nor zvuprintf()), but if they had a good reason for not having them communicate with the local zone's syslog, then an ARC case would uncover it. (Attempts at direct communication with the zones folks went unanswered.) Consider it a sanity check. --Steve
