mm/memory_hotplug: drop valid_start/valid_end from test_pages_in_a_zone()
The callers are only interested in the actual zone, they don't care about boundaries. Return the zone instead to simplify.

mm/memmap_init: update variable name in memmap_init_zone
Patch series "mm/memory_hotplug: Shrink zones before removing memory", v6.
This series fixes the access of uninitialized memmaps when shrinking
zones/nodes and when removing memory. Also, it contains all fixes for
crashes that can be triggered when removing certain namespace using
memunmap_pages() - ZONE_DEVICE, reported by Aneesh.
We stop trying to shrink ZONE_DEVICE, as it's buggy, fixing it would be
more involved (we don't have SECTION_IS_ONLINE as an indicator), and
shrinking is only of limited use (set_zone_contiguous() cannot detect the
ZONE_DEVICE as contiguous).
We continue shrinking !ZONE_DEVICE zones, however, I reduced the amount of
code to a minimum. Shrinking is especially necessary to keep
zone->contiguous set where possible, especially, on memory unplug of DIMMs
at zone boundaries.
--------------------------------------------------------------------------
Zones are now properly shrunk when offlining memory blocks or when
onlining failed. This allows to properly shrink zones on memory unplug
even if the separate memory blocks of a DIMM were onlined to different
zones or re-onlined to a different zone after offlining.
Example:
:/# cat /proc/zoneinfo
Node 1, zone Movable
spanned 0
present 0
managed 0
:/# echo "online_movable" > /sys/devices/system/memory/memory41/state
:/# echo "online_movable" > /sys/devices/system/memory/memory43/state
:/# cat /proc/zoneinfo
Node 1, zone Movable
spanned 98304
present 65536
managed 65536
:/# echo 0 > /sys/devices/system/memory/memory43/online
:/# cat /proc/zoneinfo
Node 1, zone Movable
spanned 32768
present 32768
managed 32768
:/# echo 0 > /sys/devices/system/memory/memory41/online
:/# cat /proc/zoneinfo
Node 1, zone Movable
spanned 0
present 0
managed 0
This patch (of 6):
The third argument is actually number of pages. Change the variable name
from size to nr_pages to indicate this better.
No functional change in this patch.

mm: factor out next_present_section_nr()
Let's move it to the header and use the shorter variant from mm/page_alloc.c (the original one will also check "__highest_present_section_nr + 1", which is not necessary). While at it, make the section_nr in next_pfn() const. In next_pfn(), we now return section_nr_to_pfn(-1) instead of -1 once we exceed __highest_present_section_nr, which doesn't make a difference in the caller as it is big enough (>= all sane end_pfn).

mm/page_alloc: fix and rework pfn handling in memmap_init_zone()
Let's update the pfn manually whenever we continue the loop. This makes
the code easier to read but also less error prone (and we can directly fix
one issue).
When overlap_memmap_init() returns true, pfn is updated to
"memblock_region_memory_end_pfn(r)". So it already points at the *next*
pfn to process. Incrementing the pfn another time is wrong, we might
leave one uninitialized. I spotted this by inspecting the code, so I have
no idea if this is relevant in practise (with kernelcore=mirror).

mm/page_alloc.c: initialize memmap of unavailable memory directly
Let's make sure that all memory holes are actually marked PageReserved(),
that page_to_pfn() produces reliable results, and that these pages are not
detected as "mmap" pages due to the mapcount.
E.g., booting a x86-64 QEMU guest with 4160 MB:
[ 0.010585] Early memory node ranges
[ 0.010586] node 0: [mem 0x0000000000001000-0x000000000009efff]
[ 0.010588] node 0: [mem 0x0000000000100000-0x00000000bffdefff]
[ 0.010589] node 0: [mem 0x0000000100000000-0x0000000143ffffff]
max_pfn is 0x144000.
Before this change:
[root@localhost ~]# ./page-types -r -a 0x144000,
flags page-count MB symbolic-flags long-symbolic-flags
0x0000000000000800 16384 64 ___________M_______________________________ mmap
total 16384 64
After this change:
[root@localhost ~]# ./page-types -r -a 0x144000,
flags page-count MB symbolic-flags long-symbolic-flags
0x0000000100000000 16384 64 ___________________________r_______________ reserved
total 16384 64
IOW, especially the unavailable physical memory ("memory hole") in the
last section would not get properly marked PageReserved() and is indicated
to be "mmap" memory.
Drop the trace of that function from include/linux/mm.h - nobody else
needs it, and rename it accordingly.
Note: The fake zone/node might not be covered by the zone/node span. This
is not an urgent issue (for now, we had the same node/zone due to the
zeroing). We'll need a clean way to mark memory holes (e.g., using a page
type PageHole() if possible or a fake ZONE_INVALID) and eventually stop
marking these memory holes PageReserved().

fs/proc/page.c: allow inspection of last section and fix end detection
If max_pfn does not fall onto a section boundary, it is possible to inspect PFNs up to max_pfn, and PFNs above max_pfn, however, max_pfn itself can't be inspected. We can have a valid (and online) memmap at and above max_pfn if max_pfn is not aligned to a section boundary. The whole early section has a memmap and is marked online. Being able to inspect the state of these PFNs is valuable for debugging, especially because max_pfn can change on memory hotplug and expose these memmaps. Also, querying page flags via "./page-types -r -a 0x144001," (tools/vm/page-types.c) inside a x86-64 guest with 4160MB under QEMU results in an (almost) endless loop in user space, because the end is not detected properly when starting after max_pfn. Instead, let's allow to inspect all pages in the highest section and return 0 directly if we try to access pages above that section. While at it, check the count before adjusting it, to avoid masking user errors.

mm/page_alloc.c: fix uninitialized memmaps on a partially populated last section
Patch series "mm: fix max_pfn not falling on section boundary", v2. Playing with different memory sizes for a x86-64 guest, I discovered that some memmaps (highest section if max_mem does not fall on the section boundary) are marked as being valid and online, but contain garbage. We have to properly initialize these memmaps. Looking at /proc/kpageflags and friends, I found some more issues, partially related to this. This patch (of 3): If max_pfn is not aligned to a section boundary, we can easily run into BUGs. This can e.g., be triggered on x86-64 under QEMU by specifying a memory size that is not a multiple of 128MB (e.g., 4097MB, but also 4160MB). I was told that on real HW, we can easily have this scenario (esp., one of the main reasons sub-section hotadd of devmem was added). The issue is, that we have a valid memmap (pfn_valid()) for the whole section, and the whole section will be marked "online". pfn_to_online_page() will succeed, but the memmap contains garbage. E.g., doing a "./page-types -r -a 0x144001" when QEMU was started with "-m 4160M" - (see tools/vm/page-types.c): [ 200.476376] BUG: unable to handle page fault for address: fffffffffffffffe [ 200.477500] #PF: supervisor read access in kernel mode [ 200.478334] #PF: error_code(0x0000) - not-present page [ 200.479076] PGD 59614067 P4D 59614067 PUD 59616067 PMD 0 [ 200.479557] Oops: 0000 [#4] SMP NOPTI [ 200.479875] CPU: 0 PID: 603 Comm: page-types Tainted: G D W 5.5.0-rc1-next-20191209 #93 [ 200.480646] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.12.0-59-gc9ba5276e321-prebuilt.qemu4 [ 200.481648] RIP: 0010:stable_page_flags+0x4d/0x410 [ 200.482061] Code: f3 ff 41 89 c0 48 b8 00 00 00 00 01 00 00 00 45 84 c0 0f 85 cd 02 00 00 48 8b 53 08 48 8b 2b 48f [ 200.483644] RSP: 0018:ffffb139401cbe60 EFLAGS: 00010202 [ 200.484091] RAX: fffffffffffffffe RBX: fffffbeec5100040 RCX: 0000000000000000 [ 200.484697] RDX: 0000000000000001 RSI: ffffffff9535c7cd RDI: 0000000000000246 [ 200.485313] RBP: ffffffffffffffff R08: 0000000000000000 R09: 0000000000000000 [ 200.485917] R10: 0000000000000000 R11: 0000000000000000 R12: 0000000000144001 [ 200.486523] R13: 00007ffd6ba55f48 R14: 00007ffd6ba55f40 R15: ffffb139401cbf08 [ 200.487130] FS: 00007f68df717580(0000) GS:ffff9ec77fa00000(0000) knlGS:0000000000000000 [ 200.487804] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 200.488295] CR2: fffffffffffffffe CR3: 0000000135d48000 CR4: 00000000000006f0 [ 200.488897] Call Trace: [ 200.489115] kpageflags_read+0xe9/0x140 [ 200.489447] proc_reg_read+0x3c/0x60 [ 200.489755] vfs_read+0xc2/0x170 [ 200.490037] ksys_pread64+0x65/0xa0 [ 200.490352] do_syscall_64+0x5c/0xa0 [ 200.490665] entry_SYSCALL_64_after_hwframe+0x49/0xbe But it can be triggered much easier via "cat /proc/kpageflags > /dev/null" after cold/hot plugging a DIMM to such a system: [root@localhost ~]# cat /proc/kpageflags > /dev/null [ 111.517275] BUG: unable to handle page fault for address: fffffffffffffffe [ 111.517907] #PF: supervisor read access in kernel mode [ 111.518333] #PF: error_code(0x0000) - not-present page [ 111.518771] PGD a240e067 P4D a240e067 PUD a2410067 PMD 0 This patch fixes that by at least zero-ing out that memmap (so e.g., page_to_pfn() will not crash).

ocfs2: fix oops when writing cloned file
Writing a cloned file triggers a kernel oops and the user-space command process is also killed by the system. The bug can be reproduced stably via: 1) create a file under ocfs2 file system directory. journalctl -b > aa.txt 2) create a cloned file for this file. reflink aa.txt bb.txt 3) write the cloned file with dd command. dd if=/dev/zero of=bb.txt bs=512 count=1 conv=notrunc The dd command is killed by the kernel, then you can see the oops message via dmesg command.

material.
- fix race in tree-mod-log element tracking
- fix bio flushing inside extent writepages
- fix assertion when in-memory tracking of discarded extents finds an
empty tree (eg. after adding a new device)
- update logic of temporary read-only block groups to take into
account overcommit
- fix some fixup worker corner cases:
- page could not go through proper COW cycle and the dirty status
is lost due to page migration
- deadlock if delayed allocation is performed under page lock
- fix send emitting invalid clones within the same file
- fix statfs reporting 0 free space when global block reserve size is
larger than remaining free space but there is still space for new
chunks"

kgdb patches for 5.6-rc1
Everything for kgdb this time around is either simplifications or clean ups. In particular Douglas Anderson's modifications to the backtrace machine in the *last* dev cycle have enabled Doug to tidy up some MIPS specific backtrace code and stop sharing certain data structures across the kernel. Note that The MIPS folks were on Cc: for the MIPS patch and reacted positively (but without an explicit Acked-by). Doug also got rid of the implicit switching between tasks and register sets during some but not of kdb's backtrace actions (because the implicit switching was either confusing for users, pointless or both). Finally there is a coverity fix and patch to replace open coded console traversal with the proper helper function.

Char/Misc fix for 5.6-rc1
Here is a single patch, that fixes up a commit that came in the previous char/misc merge. It fixes a bug in the hpet driver that everyone keeps tripping over in their automated testing.

btrfs: do not zero f_bavail if we have available space
There was some logic added a while ago to clear out f_bavail in statfs() if we did not have enough free metadata space to satisfy our global reserve. This was incorrect at the time, however didn't really pose a problem for normal file systems because we would often allocate chunks if we got this low on free metadata space, and thus wouldn't really hit this case unless we were actually full. Fast forward to today and now we are much better about not allocating metadata chunks all of the time. Couple this with |

vfs: fix do_last() regression
Brown paperbag time: fetching ->i_uid/->i_mode really should've been
done from nd->inode. I even suggested that, but the reason for that has
slipped through the cracks and I went for dir->d_inode instead - made
for more "obvious" patch.
Analysis:
- at the entry into do_last() and all the way to step_into(): dir (aka
nd->path.dentry) is known not to have been freed; so's nd->inode and
it's equal to dir->d_inode unless we are already doomed to -ECHILD.
inode of the file to get opened is not known.
- after step_into(): inode of the file to get opened is known; dir
might be pointing to freed memory/be negative/etc.
- at the call of may_create_in_sticky(): guaranteed to be out of RCU
mode; inode of the file to get opened is known and pinned; dir might
be garbage.
The last was the reason for the original patch. Except that at the
do_last() entry we can be in RCU mode and it is possible that
nd->path.dentry->d_inode has already changed under us.
In that case we are going to fail with -ECHILD, but we need to be
careful; nd->inode is pointing to valid struct inode and it's the same
as nd->path.dentry->d_inode in "won't fail with -ECHILD" case, so we
should use that.

Pull rdma updates from Jason Gunthorpe:
"A very quiet cycle with few notable changes. Mostly the usual list of
one or two patches to drivers changing something that isn't quite rc
worthy. The subsystem seems to be seeing a larger number of rework and
cleanup style patches right now, I feel that several vendors are
prepping their drivers for new silicon.

Modules updates for v5.6
Summary of modules changes for the 5.6 merge window:
- Add "MS" (SHF_MERGE|SHF_STRINGS) section flags to __ksymtab_strings to
indicate to the linker that it can perform string deduplication (i.e.,
duplicate strings are reduced to a single copy in the string table).
This means any repeated namespace string would be merged to just one
entry in __ksymtab_strings.
- Various code cleanups and small fixes (fix small memleak in error path,
improve moduleparam docs, silence rcu warnings, improve error logging)

The main MIPS changes for 5.6:
- Support mremap() for the VDSO, primarily to allow CRIU to restore the
VDSO to its checkpointed location.
- Restore the MIPS32 cBPF JIT, after having reverted the enablement of
the eBPF JIT for MIPS32 systems in the 5.5 cycle.
- Improve cop0 counter synchronization behaviour whilst onlining CPUs by

RISC-V Patches for the 5.6 Merge Window, Part 1
This tag contains a handful of patches that I'd like to target for this merge
window:
* Support for kasan.
* 32-bit physical addresses on rv32i-based systems.
* Support for CONFIG_DEBUG_VIRTUAL
* DT entry for the FU540 GPIO controller, which has recently had a device
driver merged.
These boot a buildroot-based system on QEMU's virt board for me.

kcov: ignore fault-inject and stacktrace
Don't instrument 3 more files that contain debugging facilities and produce large amounts of uninteresting coverage for every syscall. The following snippets are sprinkled all over the place in kcov traces in a debugging kernel. We already try to disable instrumentation of stack unwinding code and of most debug facilities. I guess we did not use fault-inject.c at the time, and stacktrace.c was somehow missed (or something has changed in kernel/configs). This change both speeds up kcov (kernel doesn't need to store these PCs, user-space doesn't need to process them) and frees trace buffer capacity for more useful coverage. should_fail lib/fault-inject.c:149 fail_dump lib/fault-inject.c:45 stack_trace_save kernel/stacktrace.c:124 stack_trace_consume_entry kernel/stacktrace.c:86 stack_trace_consume_entry kernel/stacktrace.c:89 ... a hundred frames skipped ... stack_trace_consume_entry kernel/stacktrace.c:93 stack_trace_consume_entry kernel/stacktrace.c:86 Link: http://lkml.kernel.org/r/20200116111449.217744-1-dvyukov@gmail.com Signed-off-by: Dmitry Vyukov <dvyukov@google.com> Reviewed-by: Andrey Konovalov <andreyknvl@google.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

execve: warn if process starts with executable stack
There were few episodes of silent downgrade to an executable stack over
years:
1) linking innocent looking assembly file will silently add executable
stack if proper linker options is not given as well:
$ cat f.S
.intel_syntax noprefix
.text
.globl f
f:
ret
$ cat main.c
void f(void);
int main(void)
{
f();
return 0;
}
$ gcc main.c f.S
$ readelf -l ./a.out
GNU_STACK 0x0000000000000000 0x0000000000000000 0x0000000000000000
0x0000000000000000 0x0000000000000000 RWE 0x10
^^^
2) converting C99 nested function into a closure
https://nullprogram.com/blog/2019/11/15/
void intsort2(int *base, size_t nmemb, _Bool invert)
{
int cmp(const void *a, const void *b)
{
int r = *(int *)a - *(int *)b;
return invert ? -r : r;
}
qsort(base, nmemb, sizeof(*base), cmp);
}
will silently require stack trampolines while non-closure version will
not.
Without doubt this behaviour is documented somewhere, add a warning so
that developers and users can at least notice. After so many years of
x86_64 having proper executable stack support it should not cause too
many problems.
