Convert LSM into a static interface, as the ability to unload a security module is not required by in-tree users and potentially complicates the overall security architecture. Needlessly exported LSM symbols have been unexported, to help reduce API abuse. Parameters for the capability and root_plug modules are now specified at boot. The SECURITY_FRAMEWORK_VERSION macro has also been removed. In a nutshell, there is no safe way to unload an LSM. The modular interface is thus unecessary and broken infrastructure. It is used only by out-of-tree modules, which are often binary-only, illegal, abusive of the API and dangerous, e.g. silently re-vectoring SELinux.

A couple of updates haven't considered whether the documentation makes sense as a whole any more. Three changes here: - Remove the reference to the "DAC Addressing for Address Space Hungry Devices" section which was deleted by Jan Beulich. - Remove the comment about DMA_24BIT_MASK which became obsolete when Tobias Klauser changed the code to actually use DMA_24BIT_MASK. - Remove the section "64-bit DMA and DAC cycle support" since it's fully covered above, and contains a reference to the section deleted by Jan.

This patch adds the "reset_devices" option (that's used only by one device driver for now) to the recommended list of command line parameters for kdump. Meaning (Documentation/kernel-parameters.txt): reset_devices [KNL] Force drivers to reset the underlying device during initialization.

Johannes Berg reports (Thanks!) that &struct names are not highlighted in html output format when they are inside a DOC: block. DOC: blocks were not escaped thru xml_escape() like other kernel-doc comments were. Fixed that. However, that left a problem with <p> ($blankline_html) being processed thru xml_escape(), converting it to <p>, which isn't good for the generated html output (the <p> should remain unchanged), so this patch also introduces the notion of "local" kernel-doc meta-characters ('\\\\mnemonic:'), which are converted to html just before writing the stream to its output file. Please report any problems that you (anyone) see in "highlighting" in any output mode (text, man, html, xml). Also update copyright to include me. Signed-off-by: -

I'm going to be modifying nfsd_rename() shortly to support read-only bind mounts. This #ifdef is around the area I'm patching, and it starts to get really ugly if I just try to add my new code by itself. Using this little helper makes things a lot cleaner to use. Signed-off-by:

First of all, this makes the structure jumping look a little bit cleaner. So, this stands alone as a tiny cleanup. But, we also need 'mnt' by itself a few more times later in this series, so this isn't _just_ a cleanup. Signed-off-by:

may_open() calls vfs_permission() before it does checks for IS_RDONLY(inode). It checks _again_ inside of vfs_permission(). The check inside of vfs_permission() is going away eventually. With the mnt_want/drop_write() functions, all of the r/o checks (except for this one) are consistently done before calling permission(). Because of this, I'd like to use permission() to hold a debugging check to make sure that the mnt_want/drop_write() calls are actually being made. So, to do this: 1. remove the IS_RDONLY() check from permission() 2. enforce that you must mnt_want_write() before even calling permission() 3. actually add the debugging check to permission() We need to rearrange may_open() to do r/o checks before calling permission(). Here's the patch. Signed-off-by:

Why do we need r/o bind mounts? This feature allows a read-only view into a read-write filesystem. In the process of doing that, it also provides infrastructure for keeping track of the number of writers to any given mount. This has a number of uses. It allows chroots to have parts of filesystems writable. It will be useful for containers in the future because users may have root inside a container, but should not be allowed to write to somefilesystems. This also replaces patches that vserver has had out of the tree for several years. It allows security enhancement by making sure that parts of your filesystem read-only (such as when you don't trust your FTP server), when you don't want to have entire new filesystems mounted, or when you want atime selectively updated. I've been using the following script to test that the feature is working as desired. It takes a directory and makes a regular bind and a r/o bind mount of it. It then performs some normal filesystem operations on the three directories, including ones that are expected to fail, like creating a file on the r/o mount. This patch: Some filesystems forego the vfs and may_open() and create their own 'struct file's. This patch creates a couple of helper functions which can be used by these filesystems, and will provide a unified place which the r/o bind mount code may patch. Also, rename an existing, static-scope init_file() to a less generic name. Signed-off-by:
