So far seteuid could change uid to any existing account, given sufficient permissions of the caller. This is kind of bad since it disallows admins to refuse login to disabled or locked out accounts. Add check for the account's UF_ACCOUNTDISABLE or UF_LOCKOUT flags and don't let the user in, if one of the flags is set. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

What's new:
|
|
-----------
|
|
|
|
- Support for CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_COARSE,
|
|
CLOCK_MONOTONIC_RAW, CLOCK_BOOTTIME, CLOCK_REALTIME_ALARM,
|
|
CLOCK_BOOTTIME_ALARM clocks.
|
|
|
|
- Support for case sensitive directories. mkdir(2) automatically
|
|
creates directories within the Cygwin installation dir as case
|
|
sensitive now.
|
|
|
|
This feature requires Windows 10 1803 or later and WSL installed!
|
|
|
|
- New file ioctls's FS_IOC_GETFLAGS and FS_IOC_SETFLAGS. The actual
|
|
inode flags are Cygwin-specific. This allows to set or reset
|
|
DOS attributes, file sparseness, FS level encryption and compression,
|
|
as well as directory case sensitivity programatically.
|
|
|
|
- New tools chattr(1) and lsattr(1) to utilize setting and viewing the
|
|
aforementioned new ioctl's on the command line.
|
|
|
|
- Support for exFAT.
|
|
|
|
- Support Linux-specific open(2) flag O_PATH.
|
|
|
|
- Support Linux-specific linkat(2) flag AT_EMPTY_PATH.
|
|
|
|
- Support overrun counter for posix timers (via timer_getoverrun() or
|
|
siginfo_t::si_overrun).
|
|
|
|
- New APIs: signalfd, timerfd_create, timerfd_gettime, timerfd_settime,
|
|
timer_getoverrun.
|
|
|
|
|
|
What changed:
|
|
-------------
|
|
|
|
- clock_nanosleep, pthread_condattr_setclock and timer_create now support
|
|
all clocks, except CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID.
|
|
|
|
- clock_setres is a no-op now.
|
|
|
|
- Use the new POSIX unlink semantics on NTFS starting with Windows 10 1709.
|
|
Deleting an in-use file now actually removes the file, rather than moving
|
|
it to the recycler bin.
|
|
|
|
- Use the new POSIX rename semantics on NTFS starting with Windows 10 1809.
|
|
Renaming a file to another in-use file now actually removes the other file,
|
|
rather than moving it to the recycler bin.
|
|
|
|
- open(..., O_TMPFILE) now moves the file to the trash bin immediately,
|
|
to free the parent directory.
|
|
|
|
- Wctype functions updated to Unicode 11.0.
|
|
|
|
- Remove matherr, and SVID and X/Open math library configurations.
|
|
Default math library configuration is now IEEE.
