2016-04-21Resurrect <machine/types.h> for <sys/types.h>Sebastian Huber2-123/+143
Resurrect <machine/_user_types.h> for use in <sys/types.h>. Newlib targets may provide an own version of <machine/types.h> in their machine directory to add custom user types for <sys/types.h>. Check the _SYS_TYPES_H header guard to prevent a direct include of <machine/types.h>, since the <machine/types.h> file is a Newlib speciality.

2016-04-20Don't test pthread objects for being already initialized at init timeCorinna Vinschen1-12/+0
For all pthread init functions, POSIX says Results are undefined if pthread_FOO_init() is called specifying an already initialized pthread_FOO object. So far our pthread init functions tested the incoming object if it's already an initialized object and, if so, returned EBUSY. That's ok *iff* the object was already initialized. However, as the example in https://cygwin.com/ml/cygwin/2016-04/msg00473.html shows, an uninitialized pthread object could also accidentally look like an initialized object and then returning EBUSY is not ok. Consequentially, all those tests are dangerous. Per POSIX, an application has to know what its doing when calling any of the pthread init functions anyway, and re-initializing the object is just as well as undefined behaviour as is returning EBUSY on already initialized objects. * thread.cc (pthread_attr_init): Drop check for already initialized object. (pthread_condattr_init): Ditto. (pthread_rwlockattr_init): Ditto. (pthread_mutexattr_init): Ditto. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2016-04-19Disallow S_ISGID on directories without default ACL entriesCorinna Vinschen1-1/+13
We can't handle the S_ISGID bit if the child didn't inherit a NULL SID ACE with the S_ISGID bit set. On directories without default ACL entries we would have to add an inheritable NULL SID ACE and nothing else. This in turn results in permission problems when calling set_file_sd from set_created_file_access. That's fixable, but it would only work for files created from Cygwin while files created from native Windows tools end up with really ugly permissions. This patch only makes sure that the S_ISGID bit is reset for a directory if it has no inheritable ACEs. Still having the 's' bit shown in ls or getfacl output would be misleading. So, calling `setfacl -k' on a dir also removes the S_ISGID bit now. * sec_acl.cc (set_posix_access): Drop S_ISGID bit on directories without inheritable ACEs. Explain why.

2016-04-18Handle permissions a bit closer to POSIX 1003.1eCorinna Vinschen2-10/+10
So far we tweaked ACL_GROUP_OBJ and ACL_MASK values the same way when creating a file. We now do what POSIX requires, namely just change ACL_MASK if it's present, otherwise ACL_GROUP_OBJ. Note that we only do this at creation time. Chmod still tweaks both to create less surprising results for the unsuspecting user. Additionally make sure to take umask only into account if no ACL_MASK value is present. That has been missed so far. * sec_acl.cc (set_posix_access): Perform check for non-existant default ACEs earlier. Ignore umask also if ACL_MASK is present. Only set owner_eq_group if we're actually handling a user entry. Mention chmod in a comment. * security.cc (set_created_file_access): Perform group/mask permission setting as required by POSIX 1003.1e. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2016-04-15Use __machine_*_t_defined for internal typesSebastian Huber1-4/+4
Newlib defines defaults for internal types via <sys/_types.h> and uses <machine/_types.h> to let targets define their own type if necessary. Previously for example #ifndef __dev_t_defined typedef short __dev_t; #endif However, the __*_t_defined pattern conflicts with the glibc type guard pattern for user types, e.g. dev_t in this example. Introduce a __machine_*_t_defined pattern for internal types (defined by <machine/_types.h>, used by <sys/_types.h>). For example #ifndef __machine_dev_t_defined typedef short __dev_t; #endif Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

2016-04-13Eliminate use of Newlib-specific <machine/types.h>Sebastian Huber1-6/+1
This change solves a glibc/BSD compatibility problem. glibc and BSD use double underscore types for internal types. The Linux port of Newlib uses some glibc provided internal type definitions which are not protected by guard defines, e.g. __off_t. To avoid a conflict Newlib uses single underscore types for some internal types, e.g. _off_t. However, for BSD compatibility we have to define the internal types with double underscore names in <sys/_types.h>. The header file <machine/types.h> is Newlib-specific. It was used instead of <sys/_types.h> to provide the internal type definitions _CLOCK_T, _TIME_T_, _CLOCKID_T_, _TIMER_T_, and __suseconds_t. Move these definitions to <sys/_types.h> (there exist two instances of this file, one for Linux and one for all other targets). This makes the _HAVE_SYSTYPES configuration define obsolete (could possibly break the __RDOS__ target). Use the standard <sys/_types.h> include throughout. Move __loff_t defintion to default (non-Linux) <sys/_types.h>. Define it via _off64_t to avoid a dependency on the compiler. Provide the __off_t definition via default (non-Linux) <sys/_types.h> based on _off_t for all systems except Cygwin. For Cygwin use _off64_t. Define off_t via __off_t. Provide the __pid_t definition via default (non-Linux) <sys/_types.h>. This prevents a potential __pid_t and pid_t incompatibility. Add BSD guard defines for pid_t.

2016-04-12strxfrm/wcsxfrm: Always return length of the transformed stringCorinna Vinschen1-12/+24
Cygwin's strxfrm/wcsfrm treated a too short output buffer as an error condition and always returned the size value provided as third parameter. This is not as it's documented in POSIX.1-2008. Rather, the only error condition is an invalid input string(*). Other than that, the functions are supposed to return the length of the resulting sort key, even if the output buffer is too small. In the latter case the content of the output array is unspecified, but it's the job of the application to check that the return value is greater or equal to the provided buffer size. (*) We have to make an exception in Cygwin: strxfrm has to call the UNICODE function LCMapStringW for reasons outlined in a source comment. If the incoming multibyte string is so large that we fail to malloc the space required to convert it to a wchar_t string, we have to ser errno as well since we have nothing to call LCMapStringW with. * nlsfuncs.cc (wcsxfrm): Fix expression computing offset of trailing wchar_t NUL. Compute correct return value even if output buffer is too small. (strxfrm): Handle failing malloc. Compute correct return value even if output buffer is too small.

2016-04-05Be truthful about reporting whether readahead is availableJohannes Schindelin1-1/+2
In 7346568 (Make requested console reports work, 2016-03-16), code was introduced to report the current cursor position. It works by using a pointer that either points to the next byte in the readahead buffer, or to a NUL byte if the buffer is depleted, or the pointer is NULL. These conditions are heeded in the fhandler_console::read() method, but the condition that the pointer can point at the end of the readahead buffer was not handled properly in the get_cons_readahead_valid() method. This poses a problem e.g. in Git for Windows (which uses a slightly modified MSYS2 runtime which is in turn a slightly modified Cygwin runtime) when vim queries the cursor position and immediately goes on to read console input, erroneously thinking that the readahead buffer is valid when it is already depleted instead. This condition results in an apparent freeze that can be helped only by pressing keys repeatedly. The full Git for Windows bug report is here: https://github.com/git-for-windows/git/issues/711 Let's just teach the get_cons_readahead_valid() method to handle a depleted readahead buffer correctly.

2016-04-04Rename without-mingw-progs to with-cross-bootstrapPeter Foley6-18/+33
Rename without-mingw-progs to with-cross-bootstrap, since it now disables additional checks that are problematic for cross-compilers. When cross-compiling a toolchain targeting cygwin, building cygwin1.dll requires libgcc. However, building libgcc requires the cygwin headers to be installed. Configuring cygwin requries the mingw-crt libraries, which require the cygwin headers to be installed. Work around this circular dependency by making the --with-cross-bootstrap configure option skip cygwin's configure checks for valid mingw-crt libraries. Cygwin will still properly link against these libraries if they exist, but this allows configure to succeed even if the libraries have not been built yet. Since the mingw-crt libraries only require the cygwin headers to be installed, this allows us to successfully configure cygwin so that we can only install the headers without trying to build any libraries. winsup/ChangeLog configure.ac: rename without-mingw-progs option to with-cross-bootstrap configure: regenerate winsup/cygserver/ChangeLog configure.ac: don't check AC_WINDOWS_LIBS when using with-cross-bootstrap configure: regenerate winsup/cygwin/ChangeLog configure.ac: don't check AC_WINDOWS_LIBS when using with-cross-bootstrap configure: regenerate Signed-off-by: Peter Foley <pefoley2@pefoley.com>
