New, unified implementation of POSIX permission and ACL handling. The
|
|
new ACLs now store the POSIX ACL MASK/CLASS_OBJ permission mask, and
|
|
they allow to inherit the S_ISGID bit. ACL inheritance now really
|
|
works as desired, in a limited, but theoretically equivalent fashion
|
|
even for non-Cygwin processes.</para>
|
|
|
|
<para>To accommodate standard Windows ACLs, the POSIX permissions of
|
|
the owner and all other users in the ACL are computed using the Windows
|
|
AuthZ API. This may slow down the computation of POSIX permissions
|
|
noticably in some circumstances, but is generally more correct.
|
|
The new code also ignores SYSTEM and Administrators group permissions
|
|
when computing the MASK/CLASS_OBJ permission mask on old ACLs, and it
|
|
doesn't deny access to SYSTEM and Administrators group based on the
|
|
value of MASK/CLASS_OBJ when creating the new ACLs.</para>
|
|
|
|
<para>The new code now handles the S_ISGID bit on directories as on Linux:
|
|
Setting S_ISGID on a directory causes new files and subdirs created

within to inherit its group, rather than the primary group of the user
|
|
who created the file. This only works for files and directories
|
|
created by Cygwin processes.

Since 1.7.34, chmod does not always affect the POSIX permission mask as

handling. However, that's still far from perfect, so, as a temporary

|
workaround, chmod now checks if secondary groups and users in the ACL
|
|
have more permissions than the primary group. If so, the permissions of
|
|
the secondary users and groups will be reduced according to the mask
|
|
given by the new primary group permissions. I.e, chmod 600 will remove
|
|
all permissions from the primary group as well as all secondary user and

group entries in the ACL.

IPv6 support. New APIs getaddrinfo, getnameinfo, freeaddrinfo,

gai_strerror, in6addr_any, in6addr_loopback. On IPv6-less systems,
|
|
replacement functions are available for IPv4. On systems with IPv6
|
|
enabled, the underlying WinSock functions are used. While I tried hard
|
|
to get the functionality as POSIXy as possible, keep in mind that a
|
|
*fully* conformant implementation of getaddrinfo and other stuff is only

available starting with Windows Vista/2008.

A lot of character sets are supported now via a call to setlocale().

The setting of the environment variables $LANG, $LC_ALL or $LC_CTYPE

will be used. For instance, setting $LANG to "de_DE.ISO-8859-15" before

starting a Cygwin session will use the ISO-8859-15 character set in the

entire session. The default locale in the absence of one of the

aforementioned environment variables is "C.UTF-8".

Different Cygwin installations in different paths can be run in parallel
