Package: hurd Version: 1:0.8.git20160809-1 Severity: normal File: /bin/rpctrace
If the COMMAND argument of rpctrace does not contain slash, then
rpctrace searches for it in PATH. If the file found is a script
file, then the interpreter of the script needs to know the file
name so that it can open the file. However, when rpctrace calls
_hurd_exec_file_name, it specifies COMMAND unchanged as the file
name. The interpreter then typically does not find the file.
For example, /bin/which in debianutils 4.8 has "#! /bin/sh".
If you run:
cd /
PATH=/bin
rpctrace which
then it shows that dash outputs "/bin/sh: 0: Can't open which"
after calling dir_lookup("which" 1 0) in some directory.
rpctrace should specify the correct file name "/bin/which"
instead; then dash would be able to open the file.
Another, more complex test case:
mkdir testy
echo '#! /bin/bash' > testy/prog
echo 'printf "%s\n" "$0"' >> testy/prog
chmod +x testy/prog
PATH=$(pwd)/testy /bin/rpctrace -E PATH=/usr/bin:/bin -o /dev/null prog
Actual output:
/bin/bash: prog: No such file or directory
Expected output similar to:
/home/kalle/testy/prog
Fixing this is simple: get prefixed_name from the existing
file_name_path_lookup call, and if it isn't NULL, then use it
instead of *argv and free it afterwards.
AFAIK, the _hurd_exec_file_name patches are not yet in the
upstream Hurd, so I'm filing this in Debian only.
