[merged] reiserfs-fix-broken-xattr-handling-heap-corruption-bad-retval.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: reiserfs: fix broken xattr handling (heap corruption, bad retval) has been removed from the -mm tree. Its filename was reiserfs-fix-broken-xattr-handling-heap-corruption-bad-retval.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Jann Horn <jannh(a)google.com> Subject: reiserfs: fix broken xattr handling (heap corruption, bad retval) This fixes the following issues: - When a buffer size is supplied to reiserfs_listxattr() such that each individual name fits, but the concatenation of all names doesn't fit, reiserfs_listxattr() overflows the supplied buffer. This leads to a kernel heap overflow (verified using KASAN) followed by an out-of-bounds usercopy and is therefore a security bug. - When a buffer size is supplied to reiserfs_listxattr() such that a name doesn't fit, -ERANGE should be returned. But reiserfs instead just truncates the list of names; I have verified that if the only xattr on a file has a longer name than the supplied buffer length, listxattr() incorrectly returns zero. With my patch applied, -ERANGE is returned in both cases and the memory corruption doesn't happen anymore. Credit for making me clean this code up a bit goes to Al Viro, who pointed out that the ->actor calling convention is suboptimal and should be changed.

[merged] zram-fix-bug-storing-backing_dev.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: drivers/block/zram/zram_drv.c: fix bug storing backing_dev has been removed from the -mm tree. Its filename was zram-fix-bug-storing-backing_dev.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Peter Kalauskas <peskal(a)google.com> Subject: drivers/block/zram/zram_drv.c: fix bug storing backing_dev The call to strlcpy in backing_dev_store is incorrect. It should take the size of the destination buffer instead of the size of the source buffer. Additionally, ignore the newline character (\n) when reading the new file_name buffer. This makes it possible to set the backing_dev as follows: echo /dev/sdX > /sys/block/zram0/backing_dev The reason it worked before was the fact that strlcpy() copies 'len - 1' bytes, which is strlen(buf) - 1 in our case, so it accidentally didn't copy the trailing new line symbol. Which also means that "echo -n /dev/sdX" most likely was broken.

[PATCH v3 1/2] mm: migration: fix migration of huge PMD shared pages

by Mike Kravetz

The page migration code employs try_to_unmap() to try and unmap the source page. This is accomplished by using rmap_walk to find all vmas where the page is mapped. This search stops when page mapcount is zero. For shared PMD huge pages, the page map count is always 1 no matter the number of mappings. Shared mappings are tracked via the reference count of the PMD page. Therefore, try_to_unmap stops prematurely and does not completely unmap all mappings of the source page. This problem can result is data corruption as writes to the original source page can happen after contents of the page are copied to the target page. Hence, data is lost. This problem was originally seen as DB corruption of shared global areas after a huge page was soft offlined due to ECC memory errors. DB developers noticed they could reproduce the issue by (hotplug) offlining memory used to back huge pages. A simple testcase can reproduce the problem by creating a shared PMD mapping (note that this must be at least PUD_SIZE in size and PUD_SIZE aligned (1GB on x86)), and using migrate_pages() to migrate process pages between nodes while continually writing to the huge pages being migrated. To fix, have the try_to_unmap_one routine check for huge PMD sharing by calling huge_pmd_unshare for hugetlbfs huge pages. If it is a shared mapping it will be 'unshared' which removes the page table entry and drops the reference on the PMD page. After this, flush caches and TLB. mmu notifiers are called before locking page tables, but we can not be sure of PMD sharing until page tables are locked. Therefore, check for the possibility of PMD sharing before locking so that notifiers can prepare for the worst possible case.

please revert commit ce8556cca6 "kbuild: verify that $DEPMOD is installed" introduced in v4.18.4.

by H. Nikolaus Schaller

This patch requires that /sbin/depmod is installed and installable on the build host. But not all build hosts for cross compiling Linux are Linux systems and are able to provide a working port of depmod, especially at the file patch /sbin/depmod. I use, for example, a Darwin system to cross compile Linux and I run depmod -a on the embedded system once, after installing a new Linux kernel there. I have no problem with seeing a warning, but aborting the build process is IMHO a bad idea since the previous behaviour didn't harm many people as far as I see. Probably 99% of people compiling Linux kernels do that on Linux and 99% of those have depmod installed for optimal operation of their build host. So IMHO printing the warning is good enough. BR and thanks, Nikolaus Schaller

[PATCH] powerpc/nohash: fix pte_access_permitted()

by Christophe Leroy

Commit 5769beaf180a8 ("powerpc/mm: Add proper pte access check helper for other platforms") replaced generic pte_access_permitted() by an arch specific one. The generic one is defined as (pte_present(pte) && (!(write) || pte_write(pte))) The arch specific one is open coded checking that _PAGE_USER and _PAGE_WRITE (_PAGE_RW) flags are set, but lacking to check that _PAGE_RO and _PAGE_PRIVILEGED are unset, leading to a useless test on targets like the 8xx which defines _PAGE_RW and _PAGE_USER as 0. Commit 5fa5b16be5b31 ("powerpc/mm/hugetlb: Use pte_access_permitted for hugetlb access check") replaced some tests performed with pte helpers by a call to pte_access_permitted(), leading to the same issue. This patch rewrites powerpc/nohash pte_access_permitted() using pte helpers.

Hi Greg, This patch is not marked for 4.4-stable, but it's already in 4.9 and 4.14 stable. Please apply to 4.4-stable. This patch fixed check machanism for d_type to avoid returning d_type not supported even if underlying filesystem might be supporting it. -- SZ Lin (林上智)

[PATCH] mm: respect arch_dup_mmap() return value

by Nadav Amit

Commit d70f2a14b72a4 ("include/linux/sched/mm.h: uninline mmdrop_async(), etc") ignored the return value of arch_dup_mmap(). As a result, on x86, a failure to duplicate the LDT (e.g., due to memory allocation error), would leave the duplicated memory mapping in an inconsistent state. Fix by regarding the return value, as it was before the change.

[PATCH 9/9] power: supply: twl4030-charger: fix OF sibling-node lookup

by Johan Hovold

Use the new of_get_compatible_child() helper to lookup the usb sibling node instead of using of_find_compatible_node(), which searches the entire tree and thus can return an unrelated (non-sibling) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the parent device node). While at it, also fix the related phy-node reference leak. Fixes: f5e4edb8c888 ("power: twl4030_charger: find associated phy by more reliable means.")

It is thus possible for a user to cause a crash by concurrently manipulating the device list, e.g. by disabling slot power via sysfs on a different CPU or by initiating a remove/rescan via sysfs. This can't be fixed by acquiring pci_bus_sem because it may sleep. The simplest fix is to avoid the list iteration altogether and just check the ignore_hotplug flag on the port itself. This works because pci_ignore_hotplug() sets the flag both on the device as well as on its parent bridge. We do lose the ability to print the name of the device blocking hotplug in the debug message, but that's probably bearable.
