* Ensure that send() interrupted by a signal returns sucessfullyErik M. Bray2017-06-191-4/+4
| | | | | | | | | | When SA_RESTART is not set on a socket, a blocking send() that is interrupted mid-transition by a signal should return success (and report just how many bytes were actually transmitted). The err variable used here was not always guaranteed to be set correctly in the loop, so better to just remove it and call WSAGetLastError() explicitly.
* Define RtlGenRandom correctly in ntsecapi.h wrapperCorinna Vinschen2016-12-141-0/+1

* Rearrange RNG code slightlyCorinna Vinschen2016-12-131-1/+1
| | | | | | | | | | | | | | | In preparation of exporting getentropy/getrandom to userspace, rearrange code a bit: - Define RtlGenRandom in ntdll.h. - Drop calls to getentropy in favor of RtlGenRandom (fhandler_socket, fhandler_dev_random). - Add try/except blocks in fhandler_dev_random to return EFAULT rather than crashing if buffer pointer is invalid.

* Make sure to use the Winsock definition of FIONREAD in ioctlsocket callCorinna Vinschen2016-07-011-1/+2
| | | | | | | | | | Commit b1b46d45 introduced a regression. After redefining FIONREAD as part of restructuring newlib/Cygwin headers, the call to ioctlsocket in the FIONREAD branch of fhandler_socket::ioctl should have been changed to use the Winsock definition of FIONREAD, which I neglected. This only affects 64 bit Cygwin. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

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 Windows default ACLs, the new code 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. 2015-05-29 Corinna Vinschen <corinna@vinschen.de> Reapply POSIX ACL changes. * utils.xml (setfacl): Show new option output.

Explain why. * security.cc (get_object_attribute): Add S_IFCHR flag to attributes when calling get_posix_access. * sec_acl.cc (set_posix_access): Move merging group perms into owner perms in case of owner == group after mask has been computed.
