We've discovered a bug in the NFSv4, SL4.4, 2.6.9-42.0.10. We have an
extremely simple piece of FORTRAN
program main
integer a,b,c
read(5,*) a,b,c
stop
end
If the input matches the data type, all is ok. If, instead of a number,
you input a character for any of the 3 variables, the code as compiled
by the Intel compiler will crash performing a traceback. If the current
directory where the traceback is triggered is an NFSv4 mounted
directory, the kernel panics. /var/log/messages posts an NFSv4 race
condition before the kernel OOP's.
If you do the same in a non-NFSv4 mounted directory, everything is fine.
IF you do the same in a NFSv3 mounted directory, everything is also fine.
Any suggestions? How does one go about reporting this?
