* Introduce the 'usertemp' filesystem typeJohannes Schindelin2015-12-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * mount.cc (mount_info::from_fstab_line): Support mounting the current user's temp folder as /tmp/. This is particularly useful a feature when Cygwin's own files are write-protected. * pathnames.xml: document the new usertemp file system type Detailed explanation: In the context of Windows, there is a per-user directory for temporary files, by default specified via the environment variable %TEMP%. Let's allow to use that directory for our /tmp/ directory. With this patch, we introduce the special filesystem type "usertemp": By specifying none /tmp usertemp binary,posix=0 0 0 in /etc/fstab, the /tmp/ directory gets auto-mounted to the directory specified by the %TEMP% variable. This feature comes handy in particularly in scenarios where the administrator might want to write-protect the entire Cygwin directory yet still needs to allow users to write into the /tmp/ directory. This is the case in the context of Git for Windows, where the Cygwin (MSys2) root directory lives inside C:\Program Files and hence /tmp/ would not be writable otherwise.

* Reapply POSIX ACL changes.Corinna Vinschen2015-11-181-2/+10

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.

| | | | | | | | | | | | | | | | | | On x86_64, RtlCaptureContext() uses fxsave to save FPU/MMX/SSE state. fxsave requires that the destination address is 16-byte aligned, or it will fault. CONTEXT is already annotated __attribute__ ((aligned (16))), do the same with struct _mcontext. Rearrange ucontext_t so that it's struct _mcontext element is also correctly aligned. * include/cygwin/signal.h (struct __mcontext): 16-byte align. * include/sys/ucontext.h (ucontext_t): Ditto.
