Solaris 64bit and Y2038 bug
Hi all,

I'm runing a 64bit Solaris 9 system that supposedly isn't affected by the y2038 bug. If so, why can't I set de that from that point in time forward?

Code:
root@machine>uname -a
SunOS machine 5.9 Generic_118558-36 sun4u sparc SUNW,Sun-Fire-V440
root@machine>isainfo -b
64
root@machine>mktime -y +27
2037-09-10 16:18:18
root@machine>mktime -y +28
mktime: invalid time

Thanks in advance
BR

AFAIK the mktime utility is not part of the standard distribution for Solaris 9, it is part of a package. 32 bit apps run just fine on 64bit machines, however.

Try:
Code:
file `which mktime`

to see if the utility isn't 32 bit. I would guess it is.

Hi,

Yes, I it's a 32bit binary.

But look:

Code:
root@machine>date 091016182039
date: Invalid argument
root@done>file /usr/bin/date
/usr/bin/date:  ELF 32-bit MSB executable SPARC Version 1, dynamically linked, stripped
root@done>file /bin/ls
/bin/ls:        ELF 32-bit MSB executable SPARC Version 1, dynamically linked, stripped

Everything is compliled as 32bit binaries.

Code:
Aug 23 14:25:59 machine genunix: [ID 540533 kern.notice] ^MSunOS Release 5.9 Version Generic_118558-36 64-bit

root@doninha>eeprom | grep boot-file
boot-file: data not available.

Supposedly it will boot the the 64 bit kernel unless told otherwise:

Code:
root@machine>file /platform/sun4u/kernel/sparcv9/genunix
/platform/sun4u/kernel/sparcv9/genunix: ELF 64-bit MSB relocatable SPARCV9 Version 1

Is there something i'm missing?

The fact that your kernel is 64bit does not imply that every binary shipped with the OS is 64bit.
In Solaris, only the parts that need to be changed to 64bit is 64bit.
Everything else is still 32bit as you gain nothing from converting them to 64bit.
