walk_memory_range() was once used to iterate over sections. Now, it iterates over memory blocks. Rename the function, fixup the documentation. Also, pass start+size instead of PFNs, which is what most callers already have at hand. (we'll rework link_mem_sections() most probably soon) Follow-up patches will rework, simplify, and move walk_memory_blocks() to drivers/base/memory.c. Note: walk_memory_blocks() only works correctly right now if the start_pfn is aligned to a section start. This is the case right now, but we'll generalize the function in a follow up patch so the semantics match the documentation.

Patch series "mm: Further memory block device cleanups", v1. Some further cleanups around memory block devices. Especially, clean up and simplify walk_memory_range(). Including some other minor cleanups. This patch (of 6): We are using a mixture of "int" and "unsigned long". Let's make this consistent by using "unsigned long" everywhere. We'll do the same with memory block ids next. While at it, turn the "unsigned long i" in removable_show() into an int - sections_per_block is an int.

Since resources can be removed, locking should ensure that the resource is not removed while accessing it. However, find_next_iomem_res() does not hold the lock while copying the data of the resource. Keep holding the lock while the data is copied. While at it, change the return value to a more informative value. It is disregarded by the callers.

Commit 7635d9cb ("mm, thp, proc: report THP eligibility for each vma") introduced THPeligible bit for processes' smaps. But, when checking the eligibility for shmem vma, __transparent_hugepage_enabled() is called to override the result from shmem_huge_enabled(). It may result in the anonymous vma's THP flag override shmem's. For example, running a simple test which create THP for shmem, but with anonymous THP disabled, when reading the process's smaps, it may show: 7fc92ec00000-7fc92f000000 rw-s 00000000 00:14 27764 /dev/shm/test Size: 4096 kB ... [snip] ... ShmemPmdMapped: 4096 kB ... [snip] ... THPeligible: 0 And, /proc/meminfo does show THP allocated and PMD mapped too: ShmemHugePages: 4096 kB ShmemPmdMapped: 4096 kB This doesn't make too much sense. The shmem objects should be treated separately from anonymous THP. Calling shmem_huge_enabled() with checking MMF_DISABLE_THP sounds good enough. And, we could skip stack and dax vma check since we already checked if the vma is shmem already. Also check if vma is suitable for THP by calling transhuge_vma_suitable(). And minor fix to smaps output format and documentation.

transhuge_vma_suitable() was only available for shmem THP, but anonymous THP has the same check except pgoff check. And, it will be used for THP eligible check in the later patch, so make it available for all kind of THPs. This also helps reduce code duplication slightly. Since anonymous THP doesn't have to check pgoff, so make pgoff check shmem vma only. And regroup some functions in include/linux/mm.h to solve compile issue since transhuge_vma_suitable() needs call vma_is_anonymous() which was defined after huge_mm.h is included.

In case of NODE_NOT_IN_PAGE_FLAGS is set, we store section's node id in section_to_node_table[]. While for hot-add memory, this is missed. Without this information, page_to_nid() may not give the right node id. BTW, current online_pages works because it leverages nid in memory_block. But the granularity of node id should be mem_section wide. Link: http://lkml.kernel.org/r/20190618005537.18878-1-richardw.yang@linux.intel.comSigned-off-by:

We really don't want anything during memory hotunplug to fail. We always pass a valid memory block device, that check can go. Avoid allocating memory and eventually failing. As we are always called under lock, we can use a static piece of memory. This avoids having to put the structure onto the stack, having to guess about the stack size of callers. Patch inspired by a patch from Oscar Salvador. In the future, there might be no need to iterate over nodes at all. mem->nid should tell us exactly what to remove. Memory block devices with mixed nodes (added during boot) should properly fenced off and never removed. Link: http://lkml.kernel.org/r/20190527111152.16324-11-david@redhat.comSigned-off-by:

Let's factor out removing of memory block devices, which is only necessary for memory added via add_memory() and friends that created memory block devices. Remove the devices before calling arch_remove_memory(). This finishes factoring out memory block device handling from arch_add_memory() and arch_remove_memory().

Only memory to be added to the buddy and to be onlined/offlined by user space using /sys/devices/system/memory/... needs (and should have!) memory block devices. Factor out creation of memory block devices. Create all devices after arch_add_memory() succeeded. We can later drop the want_memblock parameter, because it is now effectively stale. Only after memory block devices have been added, memory can be onlined by user space. This implies, that memory is not visible to user space at all before arch_add_memory() succeeded. While at it - use WARN_ON_ONCE instead of BUG_ON in moved unregister_memory() - introduce find_memory_block_by_id() to search via block id - Use find_memory_block_by_id() in init_memory_block() to catch duplicates Link: http://lkml.kernel.org/r/20190527111152.16324-8-david@redhat.comSigned-off-by:

A proper arch_remove_memory() implementation is on its way, which also cleanly removes page tables in arch_add_memory() in case something goes wrong. As we want to use arch_remove_memory() in case something goes wrong during memory hotplug after arch_add_memory() finished, let's add a temporary hack that is sufficient enough until we get a proper implementation that cleans up page table entries. We will remove CONFIG_MEMORY_HOTREMOVE around this code in follow up patches. Link: http://lkml.kernel.org/r/20190527111152.16324-5-david@redhat.comSigned-off-by:

Patch series "mm/memory_hotplug: Factor out memory block devicehandling", v3. We only want memory block devices for memory to be onlined/offlined (add/remove from the buddy). This is required so user space can online/offline memory and kdump gets notified about newly onlined memory. Let's factor out creation/removal of memory block devices. This helps to further cleanup arch_add_memory/arch_remove_memory() and to make implementation of new features easier - especially sub-section memory hot add from Dan. Anshuman Khandual is currently working on arch_remove_memory(). I added a temporary solution via "arm64/mm: Add temporary arch_remove_memory() implementation", that is sufficient as a firsts tep in the context of this series. (we don't cleanup page tables in case anything goes wrong already) Did a quick sanity test with DIMM plug/unplug, making sure all devices and sysfs links properly get added/removed. Compile tested on s390x and x86-64. This patch (of 11): By converting start and size to page granularity, we actually ignore unaligned parts within a page instead of properly bailing out with an error.

Merge floppy ioctl verification fixes from Denis Efremov. This also marks the floppy driver as orphaned - it turns out that Jiri no longer has working hardware. Actual working physical floppy hardware is getting hard to find, and while Willy was able to test this, I think the driver can be considered pretty much dead from an actual hardware standpoint. The hardware that is still sold seems to be mainly USB-based, which doesn't use this legacy driver at all. The old floppy disk controller is still emulated in various VM environments, so the driver isn't going away, but let's see if anybody is interested to step up to maintain it. The lack of hardware also likely means that the ioctl range verification fixes are probably mostly relevant to anybody using floppies in a virtual environment. Which is probably also going away in favor of USB storage emulation, but who knows. Will Decon reviewed the patches but I'm not rebasing them just for that, so I'll add a Reviewed-by:Will Deacon <will@kernel.org> here instead. * floppy: MAINTAINERS: mark floppy.c orphaned floppy: fix out-of-bounds read in copy_buffer floppy: fix invalid pointer dereference in drive_name floppy: fix out-of-bounds read in next_valid_format floppy: fix div-by-zero in setup_format_params

I volunteered myself to maintain it quite some time ago back when I fixed the concurrency issues which exhibited itself only with VM-emulated devices, and at the same time I still had the physical 3.5" reader to test all the changes. The reader doesn't work any more though, so I guess it's time to step down from this super-prestigious role :p and mark floppy.c as Orphaned. Signed-off-by:

This fixes a global out-of-bounds read access in the copy_buffer function of the floppy driver. The FDDEFPRM ioctl allows one to set the geometry of a disk. The sect and head fields (unsigned int) of the floppy_drive structure are used to compute the max_sector (int) in the make_raw_rw_request function. It is possible to overflow the max_sector. Next, max_sector is passed to the copy_buffer function and used in one of the memcpy calls. An unprivileged user could trigger the bug if the device is accessible, but requires a floppy disk to be inserted. The patch adds the check for the .sect * .head multiplication for not overflowing in the set_geometry function. The bug was found by syzkaller. Signed-off-by:

This fixes the invalid pointer dereference in the drive_name function of the floppy driver. The native_format field of the struct floppy_drive_params is used as floppy_type array index in the drive_name function. Thus, the field should be checked the same way as the autodetect field. To trigger the bug, one could use a value out of range and set the drive parameters with the FDSETDRVPRM ioctl. Next, FDGETDRVTYP ioctl should be used to call the drive_name. A floppy disk is not required to be inserted. CAP_SYS_ADMIN is required to call FDSETDRVPRM. The patch adds the check for a value of the native_format field to be in the '0 <= x < ARRAY_SIZE(floppy_type)' range of the floppy_type array indices. The bug was found by syzkaller. Signed-off-by:

This fixes a divide by zero error in the setup_format_params function of the floppy driver. Two consecutive ioctls can trigger the bug: The first one should set the drive geometry with such .sect and .rate values for the F_SECT_PER_TRACK to become zero. Next, the floppy format operation should be called. A floppy disk is not required to be inserted. An unprivileged user could trigger the bug if the device is accessible. The patch checks F_SECT_PER_TRACK for a non-zero value in the set_geometry function. The proper check should involve a reasonable upper limit for the .sect and .rate fields, but it could change the UAPI. The patch also checks F_SECT_PER_TRACK in the setup_format_params, and cancels the formatting operation in case of zero. The bug was found by syzkaller. Signed-off-by:
