Symptoms:
PHKL_36485:
( SR:8606416499 CR:JAGaf76332 )
Daemons may exit on account of stack growth overflow
without giving any messages.
PHKL_34770:
( SR:8606422218 CR:JAGaf82042 )
If sigaction(2)'s SA_RESTART flag is applied to a system
call that uses a timeout, it will be reset to the full
timeout value after the system call is interrupted.
This results in timeouts longer than the original
interval if signals interrupt the system call
frequently.
Defect Description:
PHKL_36485:
( SR:8606416499 CR:JAGaf76332 )
Kernel displays the "stack growth failure" message to the
terminal associated with the process but if this called on
daemon process whose control terminal is closed, kernel
does not display the message.
Resolution:
If no associated terminal, display messages to syslog.
PHKL_34770:
( SR:8606422218 CR:JAGaf82042 )
semtimedop(2) and pw_wait(2) restart with the original
parameters each time the call is interrupted by a signal
which has the SA_RESTART flag set. The timeout is not
adjusted to the remaining timeout value.
Resolution:
The SA_RESTART flag will be ignored if semtimedop(2) or
pw_wait(2) is interrupted by a signal. These system calls
now return with errno set to EINTR instead.
Enhancement:
No
