>Synopsis: msdosfs still using 32-bit time
>Category: system
>Environment:
System : OpenBSD 5.5
Details : OpenBSD 5.5-current (GENERIC) #38: Sat Apr 12 09:34:08
MDT 2014
[email protected]:/usr/src/sys/arch/i386/compile/GENERIC
Architecture: OpenBSD.i386
Machine : i386
>Description:
touch -d 1970-01-01T00:00:00 test
The above command will set the modified date on the file to
Sun Feb 7 06:28:16 2106. I've tracked this down to
/usr/src/sys/msdosfs/msdosfs_conv.c. In the function unix2dostime it's
assigning what I believe is now a 64-bit time to a uint32_t.
>How-To-Repeat:
Mount an msdos file system and run the above command, then stat the
file.
>Fix:
Let me know if you want me to fix it but you guys can probably do it
better.
