What's new:
|
|
-----------
|
|
|
|
- New APIs: cabsl, cimagl, creall, finitel, hypotl, sqrtl.
|
|
|
|
|
|
What changed:
|
|
-------------
|
|
|
|
- Performance improvements of the new account DB handling.
|
|
|
|
- Since 1.7.34, chmod does not always affect the POSIX permission mask as
|
|
returned by stat(2) or printed by ls(1), due to the improved POSIX ACL
|
|
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.
|
|
|
|
- Change handling of group permissions if owner SID == group SID. Now the
|
|
group permissions don't mirror the user permissions anymore, thus leading
|
|
to less hassle with security-conscious applications.
|
|
|
|
- Allow group SID to be the same as owner SID for "Microsoft Accounts".
|
|
Those have the group in their user token set to the owner SID by default.
|
|
Drop the workaround to change their primary group to "Users". It's not
|
|
required anymore due to the aforementioned changes.

|
|
|
|
- Generate unique inode number for /dev/tty under all circumstances.

|
|
|
|
- Fix handling of PATH search in execlp and other calls to honor mount flags.
|
|
Addresses: https://cygwin.com/ml/cygwin/2015-02/msg00119.html
|
|
|
|
- Remove a debug message accidentally printed to the terminal window
|
|
if an application calls fcntl(F_SETFL) erroneously.
|
|
|
|
- Two regressions in 1.7.34 acl(SETACL, ...):
|
|
|
|
- SETACL overwrote the incoming acltent_t array for bookkeeping purposes
|
|
while iterating over its entries. This broke reusing the acl in the
|
|
calling application (e.g. setfacl).
|
|
Addresses: https://cygwin.com/ml/cygwin/2015-02/msg00304.html
|
|
|
|
- SETACL accidentally missed to grant owner FILE_WRITE_ATTRIBUTES access.
|
|
Addresses: https://cygwin.com/ml/cygwin/2015-02/msg00457.html
|
|
|
|
- Keep SETACL from duplicating user/group deny/allow ACEs if owner SID is
|
|
the same as group SID.
|
|
|
|
- When creating directories, keep permissions inherited from parent directory
|
|
inheritable, per POSIX 1003.1e.
|
|
|
|
- 64 bit: Export forgotten symbol __mempcpy.

|
|
reported in https://cygwin.com/ml/cygwin-developers/2014-11/msg00000.html
|
|
was incomplete and lead to undesired buffering in non-canonical mode.
|
|
This should be fixed now.
