Hi, all When i ran cygwin 2.x, i used mkfifo -m 0600 file to create a named pipe with no user and group permissions.
in the latest cygwin the above command creates device with 0644 permissions. And i cant drop it to 0600: cygcheck.exe -V cygcheck (cygwin) 3.1.4 $ umask 0077 $ touch somefile; ls -l somefile -rw------- 1 admin absent 0 may 26 18:15 somefile $ mkfifo -m 0600 somefifo; ls -l somefifo prw-r--r-- 1 admin absent 0 may 26 18:16 somefifo $ chmod 600 somefifo; ls -l somefifo prw-r--r-- 1 admin absent 0 may 26 18:16 somefifo In old-good cygwin 2.x the command works as expected: $ cygcheck.exe -V cygcheck (cygwin) 2.9.0 $ umask 0022 $ mkfifo -m 0600 somefifo; ls -l somefifo prw------- 1 builduser Domain Users 0 May 26 18:21 somefifo I've also questioned the topic at https://superuser.com/questions/1555204/cygwin-3-x-mkfifo-m0600-creates-named-pipe-with-0644-permissions best regards, Yoshi kakbudto -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
