Re: saved IDs and exec (standard violation?)

[Marcus Brinkmann]

Hi,

here is the test program and the Makefile I used to reproduce this.  The
test program does not have a fork() anymore (I had one, but it messed up the
output and wasn't relevant anyway, so I removed it).

Here is the output on GNU/Linux:
marcus@ulysses[0]:/tmp$ make check
cc     savedid-test.c   -o savedid-test
cp savedid-test savedid-test-nogid
sudo chgrp utmp savedid-test
sudo chmod g+s savedid-test
./savedid-test
Startup: Real ID 1005, Effective ID 43.
Preexec: Real ID 1005, Effective ID 1005.
Startup: Real ID 1005, Effective ID 1005.
Seteuid: Real ID 1005, Effective ID 1005.

Here on GNU/Hurd:
marcus@drizzt:~$ make check
cc     savedid-test.c   -o savedid-test
cp savedid-test savedid-test-nogid
sudo chgrp utmp savedid-test
sudo chmod g+s savedid-test
./savedid-test
Startup: Real ID 1000, Effective ID 43.
Preexec: Real ID 1000, Effective ID 1000.
Startup: Real ID 1000, Effective ID 1000.
Seteuid: Real ID 1000, Effective ID 43.

Thanks,
Marcus
