[Bug-tar] tar: ../tmp/a.log: Member name contains `..'

[Na (Anne) Zou]

Hi, Sir or Madam,

Yesterday I ran “tar cvfz ../tmp.tgz ../tmp” under i386-Linux, then get tmp.tgz successfully. Since I’ll take it to customer, I check it in my PC, winrar can untar it. But when I run “tar xvfz tmp.tgz” in customer’s Linux system, it failed with message “tar: ../tmp/a.log: Member name contains `..'”. It caused me one hour to get data transport again.

 

I tried in the same Sun computer later. As soon as “..” is involved, untar can’t be done although tar can be completed successfully. I suggest solving this bug if it is a bug. If it can’t be solved, please at lease warn people when they tar it.

 

Thanks.
