2012-11-15TTY: call tty_port_destroy in the rest of driversJiri Slaby
After commit "TTY: move tty buffers to tty_port", the tty buffers are not freed in some drivers. This is because tty_port_destructor is not called whenever a tty_port is freed. This was an assumption I counted with but was unfortunately untrue. So fix the drivers to fulfil this assumption. To be sure, the TTY buffers (and later some stuff) are gone along with the tty_port, we have to call tty_port_destroy at tear-down places. This is mostly where the structure containing a tty_port is freed. This patch does exactly that -- put tty_port_destroy at those places.

2012-10-22staging: zram: Fix handling of incompressible pagesNitin Gupta
Change 130f315a (staging: zram: remove special handle of uncompressed page) introduced a bug in the handling of incompressible pages which resulted in memory allocation failure for such pages. When a page expands on compression, say from 4K to 4K+30, we were trying to do zsmalloc(pool, 4K+30). However, the maximum size which zsmalloc can allocate is PAGE_SIZE (for obvious reasons), so such allocation requests always return failure (0). For a page that has compressed size larger than the original size (this may happen with already compressed or random data), there is no point storing the compressed version as that would take more space and would also require time for decompression when needed again. So, the fix is to store any page, whose compressed size exceeds a threshold (max_zpage_size), as-it-is i.e. without compression. Memory required for storing this uncompressed page can then be requested from zsmalloc which supports PAGE_SIZE sized allocations. Lastly, the fix checks that we do not attempt to "decompress" the page which we stored in the uncompressed form -- we just memcpy() out such pages.

2012-10-22staging: comedi: ni_labpc: fix possible NULL deref during detachIan Abbott
`labpc_common_detach()` is called by the comedi core to clean up if either `labpc_attach()` (including the one in the "ni_labpc_cs" module) or `labpc_attach_pci()` returns an error. It assumes the `thisboard` macro (expanding to `((struct labpc_board_struct *)dev->board_ptr)`) is non-null. This is a valid assumption if `labpc_attach()` fails, but not if `labpc_attach_pci()` fails, leading to a possible NULL pointer dereference. Check `thisboard` at the top of `labpc_common_detach()` and return early if it is `NULL`. This is okay because the only other thing that could have been allocated is `dev->private` and that is freed by the comedi core, not by this function.

2012-10-22staging: comedi: amplc_pc236: fix invalid register access during detachIan Abbott
`pc236_detach()` is called by the comedi core if it attempted to attach a device and failed. `pc236_detach()` calls `pc236_intr_disable()` if the comedi device private data pointer (`devpriv`) is non-null. This test is insufficient as `pc236_intr_disable()` accesses hardware registers and the attach routine may have failed before it has saved their I/O base addresses. Fix it by checking `dev->iobase` is non-zero before calling `pc236_intr_disable()` as that means the I/O base addresses have been saved and the hardware registers can be accessed. It also implies the comedi device private data pointer is valid, so there is no need to check it.

2012-10-22staging: comedi: amplc_dio200: fix possible NULL deref during detachIan Abbott
`dio200_detach()` is called by the comedi core to clean up if either `dio200_attach()` or `dio200_attach_pci()` return an error. It assigns `thisboard` to the return value of `comedi_board(dev)` and assumes it is non-null. In the case of a previous call to `dio200_attach()` it won't be `NULL` because the comedi core will have pointed it to one of the elements of `dio200_boards[]`, but in the case of a previous call to `dio200_attach_pci()` it could be `NULL`, leading to a null pointer dereference. Check that `thisboard` is valid at the top of `dio200_detach()` and return early if it is `NULL`. This is okay because the only other thing that could have been allocated is `dev->private` and that is freed by the comedi core, not by this function.

It currently assumes that both `board` (assigned from the return value of `comedi_board(dev)`) and `devpriv` (assigned from `dev->private`) are non-null, but they might be null, leading to a null pointer dereference. `pci_8255_detach()` doesn't need to do anything if either `board` or `devpriv` are null, so just return early in this case.

2012-10-09mm: kill vma flag VM_RESERVED and mm->reserved_vm counterKonstantin Khlebnikov
A long time ago, in v2.4, VM_RESERVED kept swapout process off VMA, currently it lost original meaning but still has some effects: | effect | alternative flags -+------------------------+--------------------------------------------- 1| account as reserved_vm | VM_IO 2| skip in core dump | VM_IO, VM_DONTDUMP 3| do not merge or expand | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP 4| do not mlock | VM_IO, VM_DONTEXPAND, VM_HUGETLB, VM_PFNMAP This patch removes reserved_vm counter from mm_struct. Seems like nobody cares about it, it does not exported into userspace directly, it only reduces total_vm showed in proc. Thus VM_RESERVED can be replaced with VM_IO or pair VM_DONTEXPAND | VM_DONTDUMP. remap_pfn_range() and io_remap_pfn_range() set VM_IO|VM_DONTEXPAND|VM_DONTDUMP. remap_vmalloc_range() set VM_DONTEXPAND | VM_DONTDUMP.

2012-10-09mm: kill vma flag VM_CAN_NONLINEARKonstantin Khlebnikov
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.

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media updates from Mauro Carvalho Chehab: "The first part of the media updates for Kernel 3.7. This series contain: - A major tree renaming patch series: now, drivers are organized internally by their used bus, instead of by V4L2 and/or DVB API, providing a cleaner driver location for hybrid drivers that implement both APIs, and allowing to cleanup the Kconfig items and make them more intuitive for the end user; - Media Kernel developers are typically very lazy with their duties of keeping the MAINTAINERS entries for their drivers updated. As now the tree is more organized, we're doing an effort to add/update those entries for the drivers that aren't currently orphan; - Several DVB USB drivers got moved to a new DVB USB v2 core; the new core fixes several bugs (as the existing one that got bitroted). Now, suspend/resume finally started to work fine (at least with some devices - we should expect more work with regards to it); - added multistream support for DVB-T2, and unified the API for DVB-S2 and ISDB-S. Backward binary support is preserved; - as usual, a few new drivers, some V4L2 core improvements and lots of drivers improvements and fixes. There are some points to notice on this series: 1) you should expect a trivial merge conflict on your tree, with the removal of Documentation/feature-removal-schedule.txt: this series would be adding two additional entries there. I opted to not rebase it due to this recent change; 2) With regards to the PCTV 520e udev-related breakage, I opted to fix it in a way that the patches can be backported to 3.5 even without your firmware fix patch. This way, Greg doesn't need to rush backporting your patch (as there are still the firmware cache and firmware path customization issues to be addressed there). I'll send later a patch (likely after the end of the merge window) reverting the rest of the DRX-K async firmware request, fully restoring its original behaviour to allow media drivers to initialize everything serialized as before for 3.7 and upper. 3) I'm planning to work on this weekend to test the DMABUF patches for V4L2. The patches are on my queue for several Kernel cycles, but, up to now, there is/was no way to test the series locally. I have some concerns about this particular changeset with regards to security issues, and with regards to the replacement of the old VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to GPU drivers change. The Overlay API allows direct PCI2PCI transfers from a media capture card into the GPU framebuffer, but its API is crappy. Also, the only existing X11 driver that implements it requires a XV extension that is not available anymore on modern drivers. The DMABUF can do the same thing, but with it is promising to be a properly-designed API. If I can successfully test this series and be happy with it, I should be asking you to pull them next week." * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (717 commits) em28xx: regression fix: use DRX-K sync firmware requests on em28xx drxk: allow loading firmware synchrousnously em28xx: Make all em28xx extensions to be initialized asynchronously [media] tda18271: properly report read errors in tda18271_get_id [media] tda18271: delay IR & RF calibration until init() if delay_cal is set [media] MAINTAINERS: add Michael Krufky as tda827x maintainer [media] MAINTAINERS: add Michael Krufky as tda8290 maintainer [media] MAINTAINERS: add Michael Krufky as cxusb maintainer [media] MAINTAINERS: add Michael Krufky as lg2160 maintainer [media] MAINTAINERS: add Michael Krufky as lgdt3305 maintainer [media] MAINTAINERS: add Michael Krufky as mxl111sf maintainer [media] MAINTAINERS: add Michael Krufky as mxl5007t maintainer [media] MAINTAINERS: add Michael Krufky as tda18271 maintainer [media] s5p-tv: Report only multi-plane capabilities in vidioc_querycap [media] s5p-mfc: Fix misplaced return statement in s5p_mfc_suspend() [media] exynos-gsc: Add missing static storage class specifiers [media] exynos-gsc: Remove <linux/version.h> header file inclusion [media] s5p-fimc: Fix incorrect condition in fimc_lite_reqbufs() [media] s5p-tv: Fix potential NULL pointer dereference error [media] s5k6aa: Fix possible NULL pointer dereference ...

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull vfs update from Al Viro: - big one - consolidation of descriptor-related logics; almost all of that is moved to fs/file.c (BTW, I'm seriously tempted to rename the result to fd.c. 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)." Fix up trivial conflicts in the android binder driver, and some fairly simple conflicts due to two different changes to the sock_alloc_file() interface ("take descriptor handling from sock_alloc_file() to callers" vs "net: Providing protocol type via system.sockprotoname xattr of /proc/PID/fd entries" adding a dentry name to the socket) * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (72 commits) MAX_LFS_FILESIZE should be a loff_t compat: fs: Generic compat_sys_sendfile implementation fs: push rcu_barrier() from deactivate_locked_super() to filesystems btrfs: reada_extent doesn't need kref for refcount coredump: move core dump functionality into its own file coredump: prevent double-free on an error path in core dumper usb/gadget: fix misannotations fcntl: fix misannotations ceph: don't abuse d_delete() on failure exits hypfs: ->d_parent is never NULL or negative vfs: delete surplus inode NULL check switch simple cases of fget_light to fdget new helpers: fdget()/fdput() switch o2hb_region_dev_write() to fget_light() proc_map_files_readdir(): don't bother with grabbing files make get_file() return its argument vhost_set_vring(): turn pollstart/pollstop into bool switch prctl_set_mm_exe_file() to fget_light() switch xfs_find_handle() to fget_light() switch xfs_swapext() to fget_light() ...

This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation.
