* Treat ACLs with extra ACEs for Admins and SYSTEM like a trivial ACLCorinna Vinschen2016-01-283-20/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX.1e requires that chmod changes the MASK rather than the GROUP_OBJ value if the ACL is non-trivial. On Windows, especially on home machines, a standard ACL often consists of entries for the user, maybe the group, and additional entries for SYSTEM and the Administrators group. A user calling chmod on a file with bog standard Windows perms usually expects that chmod changes the GROUP_OBJ perms, but given the rules from POSIX.1e we can't do that. However, since we already treat Admins and SYSTEM special in a ACL (they are not used in MASK computations) we go a step in the Windows direction to follow user expectations. If an ACL only consists of the three POSIX permissions, plus entries for Admins and SYSTEM *only*, then we change the permissions of the GROUP_OBJ entry *and* the MASK entry. * fhandler_disk_file.cc (fhandler_disk_file::chmod): Drop unused code. Add special handling for a "standard" Windows ACL. Add comment to explain. * sec_acl.cc (get_posix_access): Allow to return "standard-ness" of an ACL to the caller. Add preceeding comment to explain a bit. * security.h (get_posix_access): Align prototype. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Don't use LoadLibraryEx(..., LOAD_LIBRARY_SEARCH_SYSTEM32). It hangsCorinna Vinschen2016-01-273-31/+13
| | | | | | | | | | | | | | | | Observed running hexchat under X. For some reason the call to LoadLibraryEx(..., LOAD_LIBRARY_SEARCH_SYSTEM32) in dll_load hangs when trying to autoload MsgWaitForMultipleObjectsEx in select.cc after hexchat forks to run DNS calls. Dropping the call and just using full paths as in 2.3.1 fixes the issue. * autoload.cc (dll_load): Drop call to LoadLibraryEx with LOAD_LIBRARY_SEARCH_SYSTEM32 flag. * wincap.h (wincaps::has_load_lib_search_flags): Remove. * wincap.cc (wincaps::has_load_lib_search_flags): Drop handling this flag.

* cygpath: Avoid returning SysWOW64Corinna Vinschen2016-01-211-0/+13
| | | | | | | | | | | | | | | | | | | | | On Cygwin 32 running under WOW64: When case-correcting the path fetched with -S, the underlying Windows function fetching the normalized path returns the real path C:\Windows\SysWOW64 instead of the path redirection enabled C:\Windows\System32 path. This breaks using the result of `cygpath -S' to fetch the POSIX path of the network related files under SYSTEMROOT\drivers\etc. This path is in fact under the *real* C:\Windows\System32 and only mapped into the 32 bit C:\Windows\System32 (aka C:\Windows\SysWOW64) via path redirection. Sounds messy? This patch checks if we're running under WOW64. If so, it changes the path returned by GetSystemDirectoryW from "system32" to "Sysnative". This in turn is changed to "System32" by NtQueryInformationFile, so we're back to what we need. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Do not treat the command line or environment like pathsJohannes Schindelin2016-01-084-13/+44
| | | | | | | | | | | | | | | | | | | | | | | | * dcrt0.cc (dll_crt0_1), environ.cc (environ_init, getwinenveq, build_env), strfuncs.cc (sys_wcstombs, sys_wcstombs_alloc), wchar.c (sys_wcstombs, sys_wcstombs_alloc): avoid mis-conversions of text that does not, actually, refer to a path or file name Detailed explanation: Our WCS -> UTF conversion handles the private Unicode page specially to allow for otherwise invalid file names. However, this handling makes no sense for command-lines, nor environment variables, which we would rather convert verbatim. As a stop-gap solution, let's just introduce a version of the sys_wcstombs() function that specifically excludes that file name conversion magic. The proper solution is to change sys_wcstombs() to assume that it is not a path that wants to be converted, and introduce sys_wcstombs_path() that does, but that is a bigger task which we leave for another patch.
