Document new ACL code * new-features.xml (ov-new2.4): Add new ACL changes. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2015-11-18 23:11:10 +01:00
What's new:
-----------
- 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.
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.
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.
- New API: rpmatch.
What changed:
-------------
- setfacl(1) now allows to use the -b and -k option combined to allow reducing
an ACL to only reflect standard POSIX permissions.
Fix numeric and monetary decimal point and thousands separator in fa_IR and ps_AF locales * nlsfuncs.cc (setlocaleinfo): New macro calling __setlocaleinfo. (__setlocaleinfo): New function to set a locale-specific character to an explicit wchar_t value. (__set_lc_numeric_from_win): Handle fa_IR and ps_AF locales to return same decimal point and thousands separator characters as on Linux. (__set_lc_monetary_from_win): Ditto for monetary characters.

Fix race condition when waiting for a signal * cygtls.h (_cygtls::wait_signal_arrived): Renamed from set_signal_arrived. (_cygtls::set_signal_arrived): New function signalling signal_arrived. (_cygtls::reset_signal_arrived): Don't reset will_wait_for_signal. (_cygtls::unwait_signal_arrived): New function only resetting will_wait_for_signal. (class wait_signal_arrived): Rename from set_signal_arrived. Accommodate name change throughout Cygwin. (wait_signal_arrived::~wait_signal_arrived): Call _cygtls::unwait_signal_arrived. Add comment. * cygserver_ipc.h (ipc_set_proc_info): Fetch signal_arrived handle via call to _cygtls::get_signal_arrived. * exceptions.cc (_cygtls::interrupt_setup): Signal signal_arrived via call to _cygtls::set_signal_arrived. (_cygtls::handle_SIGCONT): Ditto. * fhandler_socket.cc (fhandler_socket::wait_for_events): Generate WSAEVENT array prior to entering wait loop. Add cancel event object if available. Remove calls to pthread_testcancel and just call pthread::static_cancel_self if the cancel event object is signalled. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
