| * Staging: android: binder: Allow using highmem for binder buffersArve Hjønnevåg2012-10-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | The default kernel mapping for the pages allocated for the binder buffers is never used. Set the __GFP_HIGHMEM flag when allocating these pages so we don't needlessly use low memory pages that may be required elsewhere.

* mm: kill vma flag VM_CAN_NONLINEARKonstantin Khlebnikov2012-10-091-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move actual pte filling for non-linear file mappings into the new special vma operation: ->remap_pages(). Filesystems must implement this method to get non-linear mapping support, if it uses filemap_fault() then generic_file_remap_pages() can be used. Now device drivers can implement this method and obtain nonlinear vma support.

As it is, we have a situation when file_table.c is about handling of struct file and file.c is about handling of descriptor tables; the reasons are historical - file_table.c used to be about a static array of struct file we used to have way back). A lot of stray ends got cleaned up and converted to saner primitives, disgusting mess in android/binder.c is still disgusting, but at least doesn't poke so much in descriptor table guts anymore. A bunch of relatively minor races got fixed in process, plus an ext4 struct file leak. - related thing - fget_light() partially unuglified; see fdget() in there (and yes, it generates the code as good as we used to have). - also related - bits of Cyrill's procfs stuff that got entangled into that work; _not_ all of it, just the initial move to fs/proc/fd.c and switch of fdinfo to seq_file. - Alex's fs/coredump.c spiltoff - the same story, had been easier to take that commit than mess with conflicts. The rest is a separate pile, this was just a mechanical code movement. - a few misc patches all over the place. Not all for this cycle, there'll be more (and quite a few currently sit in akpm's tree)."

| * expose a low-level variant of fd_install() for binderAl Viro2012-09-261-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar situation to that of __alloc_fd(); do not use unless you really have to. You should not touch any descriptor table other than your own; it's a sure sign of a really bad API design. As with __alloc_fd(), you *must* use a first-class reference to struct files_struct; something obtained by get_files_struct(some task) (let alone direct task->files) will not do. It must be either current->files, or obtained by get_files_struct(current) by the owner of that sucker and given to you. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
| * new helper: __alloc_fd()Al Viro2012-09-261-54/+5
| | | | | | | | | | | | | | | | | | | | | | Essentially, alloc_fd() in a files_struct we own a reference to. Most of the time wanting to use it is a sign of lousy API design (such as android/binder). It's *not* a general-purpose interface; better that than open-coding its guts, but again, playing with other process' descriptor table is a sign of bad design.

This allows the code to code to compile with user namespaces enabled and removes the assumption there is only the initial user namespace. Everything is converted except for the most complex of the filesystems: autofs4, 9p, afs, ceph, cifs, coda, fuse, gfs2, ncpfs, nfs, ocfs2 and xfs as those patches need a bit more review. The strategy is to push kuid_t and kgid_t values are far down into subsystems and filesystems as reasonable. Leaving the make_kuid and from_kuid operations to happen at the edge of userspace, as the values come off the disk, and as the values come in from the network. Letting compile type incompatible compile errors (present when user namespaces are enabled) guide me to find the issues. The most tricky areas have been the places where we had an implicit union of uid and gid values and were storing them in an unsigned int. Those places were converted into explicit unions. I made certain to handle those places with simple trivial patches. Out of that work I discovered we have generic interfaces for storing quota by projid. I had never heard of the project identifiers before. Adding full user namespace support for project identifiers accounts for most of the code size growth in my git tree. Ultimately there will be work to relax privlige checks from "capable(FOO)" to "ns_capable(user_ns, FOO)" where it is safe allowing root in a user names to do those things that today we only forbid to non-root users because it will confuse suid root applications. While I was pushing kuid_t and kgid_t changes deep into the audit code I made a few other cleanups. I capitalized on the fact we process netlink messages in the context of the message sender. I removed usage of NETLINK_CRED, and started directly using current->tty. Some of these patches have also made it into maintainer trees, with no problems from identical code from different trees showing up in linux-next. After reading through all of this code I feel like I might be able to win a game of kernel trivial pursuit."

Loads of changes here, and we just narrowly added more lines than we added: 622 files changed, 28356 insertions(+), 26059 deletions(-) But, good news is that there is a number of subsystems that moved out of the staging tree, to their respective "real" portions of the kernel. Code that moved out was: - iio core code - mei driver - vme core and bridge drivers There was one broken network driver that moved into staging as a step before it is removed from the tree (pc300), and there was a few new drivers added to the tree: - new iio drivers - gdm72xx wimax USB driver - ipack subsystem and 2 drivers All of the movements around have acks from the various subsystem maintainers, and all of this has been in the linux-next tree for a while.

A bit of Makefile, Kconfig and header files adjustments were needed because of the move.

The code inside the #ifndef will go away soon, but so far we must support pstore and ram_console. So, we are about to use persistent_ram with pstore, with the ability to compile persistent_ram routines as modules. Some parts of persistent_ram uses memblock_reserve() routine, which is should be only used built-in code, and thus it is not exported. These persistent_ram bits are only used by Android's ram_console, which is always built-in. Without this patch, we won't able to compile persistent_ram as a module: ERROR: "memblock_reserve" [fs/pstore/ramoops.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2 (As alternative, we could export memblock_reserve, but the thing is: we won't need it later.)

For the normal (but unused) ram we could use kmaps, but this assumes highmem support, so we don't bother and just use the memory via ioremap. As a side effect, the following hack is possible: when used together with pstore_ram (new ramoops) module, we can limit the normal RAM region with mem= and then point ramoops to use the rest of the memory, e.g. mem=128M ramoops.mem_address=0x8000000 Sure, we could just reserve the region with memblock_reserve() early in the arch/ code, and then register a pstore_ram platform device pointing to the reserved region. It's still a viable option if platform wants to do so. Also, we might want to use IO accessors in case of a real device, but for now we don't bother (the old ramoops wasn't using it either, so at least we don't make things worse).

But when called for large data buffers, the write routine behaves incorrectly, as the size may never update: instead of clamping the size to the maximum buffer size, buffer_size_add_clamp() returns an error (which is never checked by the write routine, btw). To fix this, we now use buffer_size_add() that actually clamps the size to the max value. Also remove buffer_size_add_clamp(), it is no longer needed.
