getfacl seems to list wrong permissions for Group

getfacl seems to list wrong permissions for Group

[L Anderson]

In directory /cygwin/bin of my cygwin installation,

$ ls -l  //yields:
[snip]
-rwxr-xr-x  1 lowella Administrators 73742 Nov 14 2010 zsyncmake.exe

and

$ ls -ln  //yields
[snip]
-rwxr-xr-x  1 1000  544  73742 Nov 14  2010 zsyncmake.exe

and

$ stat -c '%A %a %n' *  //yields:
[snip]
-rwxr-xr-x 755 zsyncmake.exe

all quite consistent and pretty much as expected.
NB: zsyncmake.exe is the last file listed from /bin.

However,

$ getfacl -a zsyncmake.exe  //yields:
# file: zsyncmake.exe
# owner: lowella
# group: Administrators
user::rwx
group::---
mask:rwx
other:r-x

Why does getfacl give "group::---" instead of "group::r-x" as
appears in the ls and stat listings?  Is this a bug in getfacl?
Incidentally, any file from /bin that gets 'getfacled' shows
the same problem.

Regards,

LA

No.  getfacl shows the ACL as is (from a POSIX perspective),
the stat/ls information shows the effective POSIX permissions
for the group which are a result of the facts that "Everyone" has
r-x permissions and that permissions on Windows are cumulative.
