I'm sponsoring this fast-track for Abhinandan Ekande from RPE. The
exposure is
open, and we're seeking patch binding. Timeout is set for 04/10/2009.

2. Project Summary
2.1. 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.
