Reapply POSIX ACL changes. - New, unified implementation of POSIX permission and ACL handling. 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. (getfacl): Show new option output. * sec_acl.cc (get_posix_access): Check for Cygwin "standard" ACL. Apply umask, if so.

(fhandler_pty_slave::fchown): Fix uid/gid handling. * sec_acl.cc (set_posix_access): Drop superfluous class_idx variable. Simplify and move around code in a few places. To improve ACL readability, add r/w permissions to Admins ACE appended to pty ACL. Add comment to explain Windows ACE Mask filtering being in the way of creating a real CLASS_OBJ. (get_posix_access): Fake CLASS_OBJ for ptys. 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. Take mask into account when doing so to avoid unnecessary ACCESS_DENIED_ACE. * sec_acl.cc (get_posix_access): Only set saw_group_obj flag if we saw the ACCESS_ALLOWED_ACE. * fhandler_disk_file.cc (fhandler_disk_file::fchmod): Deliberatly set GROUP_OBJ and CLASS_OBJ perms to new group perms. Add comment to explain why. * security.cc (set_created_file_access): Ditto. * sec_acl.cc (set_posix_access): Replace previous patch. Return EINVAL if uid and/or guid is invalid and not backed by an actual Windows account. * sec_acl.cc (set_posix_access): Workaround owner/group SIDs being NULL. * sec_acl.cc (set_posix_access): Handle files with owner == group. Rephrase switch statement checking against unfiltered a_type value.

(fhandler_base::open): Explicitely umask mode on NFS here. Call new set_created_file_access rather than set_file_attribute. * fhandler_disk_file.cc (fhandler_disk_file::fchmod): Reimplement setting permissions on filesystems supporting ACLs using the new set_posix_access call. (fhandler_disk_file::fchown): Ditto. (fhandler_disk_file::mkdir): Call new set_created_file_access rather than set_file_attribute. * fhandler_socket.cc (fhandler_socket::bind): Don't umask here.

Describe how to generate deny ACEs in more detail. Accommodate the fact that a NULL deny ACE is used for {DEF_}CLASS_OBJ, rather than a special Cygwin ACE. Improve further comments. (CYG_ACE_NEW_STYLE): Define. (get_posix_access): Change from Cygwin ACE to NULL deny ACE. Fix CLASS_OBJ handling to generate CLASS_OBJ and DEF_CLASS_OBJ from a single NULL deny ACE if the inheritance flags say so. * sec_helper.cc (well_known_cygwin_sid): Remove. * security.h (well_known_cygwin_sid): Drop declaration. * sec_acl.cc (CYG_ACE_ISBITS_TO_WIN): Fix typo.

Reapply POSIX ACL changes. - New, unified implementation of POSIX permission and ACL handling. 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.

Reapply POSIX ACL changes. - New, unified implementation of POSIX permission and ACL handling. 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.

Reapply POSIX ACL changes. - New, unified implementation of POSIX permission and ACL handling. 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.

Reapply POSIX ACL changes. - New, unified implementation of POSIX permission and ACL handling. 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.

Reapply POSIX ACL changes. - New, unified implementation of POSIX permission and ACL handling. 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. (getfacl): Show new option output. * sec_acl.cc (get_posix_access): Check for Cygwin "standard" ACL. Apply umask, if so.

Reapply POSIX ACL changes. - New, unified implementation of POSIX permission and ACL handling. 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. (getfacl): Show new option output. * sec_acl.cc (get_posix_access): Check for Cygwin "standard" ACL. Apply umask, if so. Align comments. * security.cc (set_created_file_access): Fix permission masking by incoming requested file mode. * sec_acl.cc (set_posix_access): Apply mask only in terms of execute bit for SYSTEM and Admins group. * sec_acl.cc (set_posix_access): Don't create DENY ACEs for USER and GROUP entries if they are the same as USER_OBJ or GROUP_OBJ. * fhandler.h (fhandler_pty_slave::facl): Add prototype. * fhandler_tty.cc (fhandler_pty_slave::facl): New method. (fhandler_pty_slave::fchown): Fix uid/gid handling. * sec_acl.cc (set_posix_access): Drop superfluous class_idx variable. Simplify and move around code in a few places. To improve ACL readability, add r/w permissions to Admins ACE appended to pty ACL. Add comment to explain Windows ACE Mask filtering being in the way of creating a real CLASS_OBJ. (get_posix_access): Fake CLASS_OBJ for ptys. 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. Take mask into account when doing so to avoid unnecessary ACCESS_DENIED_ACE. * sec_acl.cc (get_posix_access): Only set saw_group_obj flag if we saw the ACCESS_ALLOWED_ACE. * fhandler_disk_file.cc (fhandler_disk_file::fchmod): Deliberatly set GROUP_OBJ and CLASS_OBJ perms to new group perms. Add comment to explain why. * security.cc (set_created_file_access): Ditto. * sec_acl.cc (set_posix_access): Replace previous patch. Return EINVAL if uid and/or guid is invalid and not backed by an actual Windows account. * sec_acl.cc (set_posix_access): Workaround owner/group SIDs being NULL. * sec_acl.cc (set_posix_access): Handle files with owner == group. Rephrase switch statement checking against unfiltered a_type value. (get_posix_access): Handle files with owner == group. * sec_acl.cc (get_posix_access): Don't use GROUP_OBJ access to fix up CLASS_OBJ mask on old-style ACLs. Fix a comment. * sec_acl.cc (set_posix_access): Always make sure Admins have WRITE_DAC and WRITE_OWNER permissions. * security.h (create_object_sd_from_attribute): Drop handle parameter from prototype. * security.cc (create_object_sd_from_attribute): Drop handle parameter. Just create the standard POSIXy security descriptor. (set_object_attribute): Accommodate dropped paramter in call to create_object_sd_from_attribute. * fhandler_tty.cc: Ditto, throughout. * fhandler_disk_file.cc (fhandler_disk_file::fchmod): Fix typo in mask computation. * fhandler.cc (fhandler_base::open_with_arch): Call open with mode not umasked. (fhandler_base::open): Explicitely umask mode on NFS here. Call new set_created_file_access rather than set_file_attribute. * fhandler_disk_file.cc (fhandler_disk_file::fchmod): Reimplement setting permissions on filesystems supporting ACLs using the new set_posix_access call. (fhandler_disk_file::fchown): Ditto. (fhandler_disk_file::mkdir): Call new set_created_file_access rather than set_file_attribute. * fhandler_socket.cc (fhandler_socket::bind): Don't umask here. Add WRITE_OWNER access to allow writing group in case of SGID bit set. Call new set_created_file_access rather than set_file_attribute. * path.cc (symlink_worker): Call new set_created_file_access rather than set_file_attribute. * sec_acl.cc (searchace): Un-staticize.

(get_posix_access): Add handling for just created files requiring their first Cygwin ACL. Fix new_style recognition. Handle SGID bit. For old-style ACLs, ignore SYSTEM and Administrators when computing the {DEF_}CLASS_OBJ perms. * security.cc (get_file_sd): Revamp comment. Change and (hopefully) speed up inheritance processing for just created files. (alloc_sd): Remove. (set_security_attribute): Call set_posix_access instead of alloc_sd. (get_object_attribute): Fix return value. (create_object_sd_from_attribute): Call set_posix_access instead of alloc_sd. (set_file_attribute): Remove. (set_created_file_access): New function implemented in terms of get_posix_access/set_posix_access. * security.h (set_file_attribute): Remove prototype. (set_created_file_access): Add prototype. (searchace): Ditto. (set_posix_access): Ditto. * syscalls.cc (open): Call open_with_arch with mode not umasked. * sec_acl.cc: Change preceeding comment explaining new-style ACLs. Describe how to generate deny ACEs in more detail. Accommodate the fact that a NULL deny ACE is used for {DEF_}CLASS_OBJ, rather than a special Cygwin ACE. Improve further comments. (CYG_ACE_NEW_STYLE): Define. (get_posix_access): Change from Cygwin ACE to NULL deny ACE. Fix CLASS_OBJ handling to generate CLASS_OBJ and DEF_CLASS_OBJ from a single NULL deny ACE if the inheritance flags say so. * sec_helper.cc (well_known_cygwin_sid): Remove. * security.h (well_known_cygwin_sid): Drop declaration. * sec_acl.cc (CYG_ACE_ISBITS_TO_WIN): Fix typo.

/* POSIX demands that pread/pwrite don't change the current file position.
While NtReadFile/NtWriteFile support atomic seek-and-io, both change the
file pointer if the file handle has been opened for synchonous I/O.
Using this handle for pread/pwrite would break atomicity, because the
read/write operation would have to be followed by a seek back to the old
file position. What we do is to open another handle to the file on the
first call to either pread or pwrite. This is used for any subsequent
pread/pwrite. Thus the current file position of the "normal" file
handle is not touched.
2011-12-18 07:39:47 +08:00
FIXME:
Note that this is just a hack. The problem with this approach is that
a change to the file permissions might disallow to open the file with
the required permissions to read or write. This appears to be a border case,
but that's exactly what git does. It creates the file for reading and
writing and after writing it, it chmods the file to read-only. Then it
calls pread on the file to examine the content. This works, but if git
would use the original handle to pwrite to the file, it would be broken
with our approach.
One way to implement this is to open the pread/pwrite handle right at
file open time. We would simply maintain two handles, which wouldn't
be much of a problem given how we do that for other fhandler types as
well.
However, ultimately fhandler_disk_file should become a derived class of
fhandler_base_overlapped. Each raw_read or raw_write would fetch the
actual file position, read/write from there, and then set the file
position again. Fortunately, while the file position is not maintained
by the I/O manager, it can be fetched and set to a new value by all
processes holding a handle to that file object. Pread and pwrite differ
from raw_read and raw_write just by not touching the current file pos.
Actually they could be merged with raw_read/raw_write if we add a position
parameter to the latter. */

Reapply POSIX ACL changes. - New, unified implementation of POSIX permission and ACL handling. 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.

NFS clients hide dangling symlinks from directory queries,

FileIdBothDirectoryInformation works fine, but only if the NFS
share is mounted to a drive letter. TODO: We don't test that

Worse, trying to open a symlink without setting the special

in a timeout of up to 20 seconds, followed by two exceptions
