Description andrew 2001-07-08 17:10:01 UTC

When attempting to tar a larger than 2GB file, tar immediately returns, having created 10240 byte file.
tar tvf file.tar reveals that file size is inidcated as negative!

Fix: 

Probably 32bit integers used inside tar & cpio when calculating filesizes.
How-To-Repeat: Create >2gb file
tar cvf file.tar 2gbfile.data
tar tvf file.tar

Comment 1 Andrew Webster 2001-08-05 03:47:45 UTC

I have investigated TAR code in create.c.
Problem is that counter is a 32 bit long (save_totsize) see line 198.
Should be of type off_t to deal with numbers > 2,147,483,647

Probably similar problem with cpio.
