CMA has alloc/free interface for debugging. It is intended that alloc/free occurs in specific CMA region, but, currently, alloc/free interface is on root dir due to the bug so we can't select CMA region where alloc/free happens. This patch fixes this problem by making alloc/free interface per CMA region. Signed-off-by:

Currently, we set wrong gfp_mask to page_owner info in case of isolated freepage by compaction and split page. It causes incorrect mixed pageblock report that we can get from '/proc/pagetypeinfo'. This metric is really useful to measure fragmentation effect so should be accurate. This patch fixes it by setting correct information. Without this patch, after kernel build workload is finished, number of mixed pageblock is 112 among roughly 210 movable pageblocks. But, with this fix, output shows that mixed pageblock is just 57.

When I tested my new patches, I found that page pointer which is used for setting page_owner information is changed. This is because page pointer is used to set new migratetype in loop. After this work, page pointer could be out of bound. If this wrong pointer is used for page_owner, access violation happens. Below is error message that I got.

fsnotify_clear_marks_by_group_flags() can race with fsnotify_destroy_marks() so when fsnotify_destroy_mark_locked() drops mark_mutex, a mark from the list iterated by fsnotify_clear_marks_by_group_flags() can be freed and we dereference free memory in the loop there. Fix the problem by keeping mark_mutex held in fsnotify_destroy_mark_locked(). The reason why we drop that mutex is that we need to call a ->freeing_mark() callback which may acquire mark_mutex again. To avoid this and similar lock inversion issues, we move the call to ->freeing_mark() callback to the kthread destroying the mark. Signed-off-by:

/proc/*/cmdline code checks if it should look at ENVP area by checking last byte of ARGV area: rv = access_remote_vm(mm, arg_end - 1, &c, 1, 0); if (rv <= 0) goto out_free_page; If ARGV is somehow made empty (by doing execve(..., NULL, ...) or manually setting ->arg_start and ->arg_end to equal values), the decision will be based on byte which doesn't even belong to ARGV/ENVP. So, quickly check if ARGV area is empty and report 0 to match previous behaviour. Signed-off-by:

Horacio Mijail Anton Quiles authored
A hexdump with a buf not aligned to the groupsize causes non-naturally-aligned memory accesses. This was causing a kernel panic on the processor BlackFin BF527, when such an unaligned buffer was fed by the function ubifs_scanned_corruption in fs/ubifs/scan.c . To fix this, change accesses to the contents of the buffer so they go through get_unaligned(). This change should be harmless to unaligned- access-capable architectures, and any performance hit should be anyway dwarfed by the snprintf() processing time. Signed-off-by:

Commit 2ae416b1 ("mm: new mm hook framework") introduced an empty header file (mm-arch-hooks.h) for every architecture, even those which doesn't need to define mm hooks. As suggested by Geert Uytterhoeven, this could be cleaned through the use of a generic header file included via each per architecture asm/include/Kbuild file. The PowerPC architecture is not impacted here since this architecture has to defined the arch_remap MM hook. Signed-off-by:

Some modules call config_item_init_type_name() and config_group_init_type_name() with parameter "name" directly controlled by userspace. These two functions call config_item_set_name() with this name used as a format string, which can be used to leak information such as content of the stack to userspace. For example, make_netconsole_target() in netconsole module calls config_item_init_type_name() with the name of a newly-created directory. This means that the following commands give some unexpected output, with configfs mounted in /sys/kernel/config/ and on a system with a configured eth0 ethernet interface: # modprobe netconsole # mkdir /sys/kernel/config/netconsole/target_%lx # echo eth0 > /sys/kernel/config/netconsole/target_%lx/dev_name # echo 1 > /sys/kernel/config/netconsole/target_%lx/enabled # echo eth0 > /sys/kernel/config/netconsole/target_%lx/dev_name # dmesg |tail -n1 [ 142.697668] netconsole: target (target_ffffffffc0ae8080) is enabled, disable to update parameters The directory name is correct but %lx has been interpreted in the internal item name, displayed here in the error message used by store_dev_name() in drivers/net/netconsole.c. To fix this, update every caller of config_item_set_name to use "%s" when operating on untrusted input. This issue was found using -Wformat-security gcc flag, once a __printf attribute has been added to config_item_set_name(). Signed-off-by:Nicolas Iooss <nicolas.iooss_linux@m4x.org> Acked-by:

Using __printf attributes helps to detect several format string issues at compile time (even though -Wformat-security is currently disabled in Makefile). For example it can detect when formatting a pointer as a number, like the issue fixed in commit a3fa71c4 ("wl18xx: show rx_frames_per_rates as an array as it really is"), or when the arguments do not match the format string, c.f. for example commit 5ce1aca8 ("reiserfs: fix __RASSERT format string"). To prevent similar bugs in the future, add a __printf attribute to every function prototype which needs one in include/linux/ and lib/. These functions were mostly found by using gcc's -Wsuggest-attribute=format flag. Signed-off-by:

On s390 we only can enable hugepages if the underlying hardware/hypervisor also does support this. Common code now would assume this to be signaled by setting HPAGE_SHIFT to 0. But on s390, where we only support one hugepage size, there is a link between HPAGE_SHIFT and pageblock_order. So instead of setting HPAGE_SHIFT to 0, we will implement the check for the hardware capability. Signed-off-by:

s390 has a constant hugepage size, by setting HPAGE_SHIFT we also change e.g. the pageblock_order, which should be independent in respect to hugepage support. With this patch every architecture is free to define how to check for hugepage support. Signed-off-by:

Dominik Dingel authored
Heiko noticed that the current check for hugepage support on s390 is a little bit too harsh as systems which do not support will crash. The reason is that pageblock_order can now get negative when we set HPAGE_SHIFT to 0. To avoid all this and to avoid opening another can of worms with enabling HUGETLB_PAGE_SIZE_VARIABLE I think it would be best to simply allow architectures to define their own hugepages_supported(). Revert bea41197 ("s390/mm: make hugepages_supported a boot time decision") in preparation. Signed-off-by:

Pull drm fixes from Dave Airlie: "Fixes all over the place. The rockchip and imx fixes I missed while on holidays, so I've queued them now which makes this a bit bigger. The rest is misc amdgpu, radeon, i915 and armada. I think the most important thing is the ioctl fix, we dropped the avoid compat ball, so we get to add a compat wrapper. There is also an i915 revert to avoid a regression with existing userspace" * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (43 commits) drm/ttm: improve uncached page deallocation. drm/ttm: fix uncached page deallocation to properly fill page pool v3. drm/amdgpu/dce8: Re-set VBLANK interrupt state when enabling a CRTC drm/radeon/ci: silence a harmless PCC warning drm/amdgpu/cz: silence some dpm debug output drm/amdgpu/cz: store the forced dpm level drm/amdgpu/cz: unforce dpm levels before forcing to low/high drm/amdgpu: remove bogus check in gfx8 rb setup drm/amdgpu: set proper index/data pair for smc regs on CZ (v2) drm/amdgpu: disable the IP module if early_init returns -ENOENT (v2) drm/amdgpu: stop context leak in the error path drm/amdgpu: validate the context id in the dependencies drm/radeon: fix user ptr race condition drm/radeon: Don't flush the GART TLB if rdev->gart.ptr == NULL drm/radeon: add a dpm quirk for Sapphire Radeon R9 270X 2GB GDDR5 drm/armada: avoid saving the adjusted mode to crtc->mode drm/armada: fix overlay when partially off-screen drm/armada: convert overlay to use drm_plane_helper_check_update() drm/armada: fix gem object free after failed prime import drm/armada: fix incorrect overlay plane cleanup ...

The GICv3 ITS architecture allows a given [DevID, EventID] pair to be translated to a [LPI, Collection] pair, where DevID is the device writing the MSI, EventID is the payload being written, LPI is the actual interrupt number, and Collection is roughly equivalent to a target CPU. Each LPI can be mapped to a separate collection, but the ITS driver insists on maintaining the collection on a device basis, instead of doing it on a per interrupt basis. This is obviously flawed, and this patch fixes it by adding a per interrupt index that indicates which collection number is in use. Reported-by:
