pax: Terminate loop for empty directory names

2024-06-21T16:39:09Z

Pax can sometimes loop forever. For example: $ mkdir -p /tmp/src/foo/bar $ rm -rf /tmp/dst ; mkdir -p /tmp/dst $ cd /tmp/src $ echo 'foo/bar/' | /bin/pax -r -w -d -pe "/tmp/dst" Here, pax(1) infinitely deletes and re-creates /tmp/dst/foo/bar/. The problem is that chk_path() (bin/pax/file_subs.c), called from node_creat() also creates the leaf directory when a trailing '/' appears in the directory name to create. When the execution goes back from chk_path() to node_creat(), the function still cannot create the leaf directory (it has been created by chk_path()), so it unlinks it and calls node_creat() again. The function re-creates it, and so on... In node_creat() detect trailing slashes and not create a leaf directory, but only intermediate ones. PR: 277060 Reviewed by: imp

Remove copyright strings ifdef'd out

2023-11-27T05:23:58Z

We've ifdef'd out the copyright strings for some time now. Go ahead and remove the ifdefs. Plus whatever other detritis was left over from other recent removals. These copyright strings are present in the comments and are largely from CSRG's attempt at adding their copyright to every binary file (which modern interpretations of the license doesn't require).
