[PATCH for 4.4.y] xfs: set format back to extents if xfs_bmap_extents_to_btree

by Nobuhiro Iwamatsu

From: Eric Sandeen <sandeen(a)redhat.com> commit 2c4306f719b083d17df2963bc761777576b8ad1b upstream. If xfs_bmap_extents_to_btree fails in a mode where we call xfs_iroot_realloc(-1) to de-allocate the root, set the format back to extents. Otherwise we can assume we can dereference ifp->if_broot based on the XFS_DINODE_FMT_BTREE format, and crash.

[PATCH v3 2/4] pid: Use file_receive helper to copy FDs

by Sargun Dhillon

The code to copy file descriptors was duplicated in pidfd_getfd. Rather than continue to duplicate it, this hoists the code out of kernel/pid.c and uses the newly added file_receive helper. Earlier, when this was implemented there was some back-and-forth about how the semantics should work around copying around file descriptors [1], and it was decided that the default behaviour should be to not modify cgroup data. As a matter of least surprise, this approach follows the default semantics as presented by SCM_RIGHTS. In the future, a flag can be added to avoid manipulating the cgroup data on copy.

[PATCH stable 5.4] PM: wakeup: Show statistics for deleted wakeup sources again

by Florian Fainelli

From: zhuguangqing <zhuguangqing(a)xiaomi.com> commit e976eb4b91e906f20ec25b20c152d53c472fc3fd upstream After commit 00ee22c28915 (PM / wakeup: Use seq_open() to show wakeup stats), print_wakeup_source_stats(m, &deleted_ws) is not called from wakeup_sources_stats_seq_show() any more. Because deleted_ws is one of the wakeup sources, it should be shown too, so add it to the end of all other wakeup sources.

[merged] mm-ptdump-expand-type-of-val-in-note_page.patch removed from -mm tree

The patch titled Subject: mm: ptdump: expand type of 'val' in note_page() has been removed from the -mm tree. Its filename was mm-ptdump-expand-type-of-val-in-note_page.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Steven Price <steven.price(a)arm.com> Subject: mm: ptdump: expand type of 'val' in note_page() The page table entry is passed in the 'val' argument to note_page(), however this was previously an "unsigned long" which is fine on 64-bit platforms. But for 32 bit x86 it is not always big enough to contain a page table entry which may be 64 bits. Change the type to u64 to ensure that it is always big enough.

[merged] x86-mm-ptdump-calculate-effective-permissions-correctly.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: x86: mm: ptdump: calculate effective permissions correctly has been removed from the -mm tree. Its filename was x86-mm-ptdump-calculate-effective-permissions-correctly.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Steven Price <steven.price(a)arm.com> Subject: x86: mm: ptdump: calculate effective permissions correctly Patch series "Fix W+X debug feature on x86" Jan alerted me[1] that the W+X detection debug feature was broken in x86 by my change[2] to switch x86 to use the generic ptdump infrastructure. Fundamentally the approach of trying to move the calculation of effective permissions into note_page() was broken because note_page() is only called for 'leaf' entries and the effective permissions are passed down via the internal nodes of the page tree. The solution I've taken here is to create a new (optional) callback which is called for all nodes of the page tree and therefore can calculate the effective permissions. Secondly on some configurations (32 bit with PAE) "unsigned long" is not large enough to store the table entries. The fix here is simple - let's just use a u64. [1] https://lore.kernel.org/lkml/d573dc7e-e742-84de-473d-f971142fa319@suse.com/ [2] 2ae27137b2db ("x86: mm: convert dump_pagetables to use walk_page_range") This patch (of 2): By switching the x86 page table dump code to use the generic code the effective permissions are no longer calculated correctly because the note_page() function is only called for *leaf* entries. To calculate the actual effective permissions it is necessary to observe the full hierarchy of the page tree. Introduce a new callback for ptdump which is called for every entry and can therefore update the prot_levels array correctly. note_page() can then simply access the appropriate element in the array.
