* Remove ill-advised cygwin_propsCorinna Vinschen2016-03-191-58/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cygwin_props have been invented to allow switching off the unique installation keys in the first place, supposedly for debugging. This never really was a good idea, after all we *want* the installations to be independent and there's no good reason to break that, not even for debugging purposes. Other than that, cygwin_props were meant to be used for some other global settings which never took place. There's just no good reason to tweak the DLL binary invisibly where a setting could be done in a file or the environment. This patch removes the cygwin_props entirely, including the related settings in cygcheck. cygwin: * cygprops.h: Remove file. * globals.cc (cygwin_props): Remove. * cygheap.cc (init_cygheap::init_installation_root): Drop removing installation key. utils: * cygcheck.cc: Drop including cygprops.h. Remove now unused option values. (unique_object_name_opt): Remove. (handle_unique_object_name): Remove function. (usage): Remove text for unique-object-names options. (longopts): Remove unique-object-names options. (main): Drop handling unique-object-names options. doc: * utils.xml (cygcheck): Remove text for unique-object-names options.

* Introduce the 'usertemp' filesystem typeJohannes Schindelin2015-12-072-3/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

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.
