mm: fix kthread_use_mm() vs TLB invalidate
For SMP systems using IPI based TLB invalidation, looking at current->active_mm is entirely reasonable. This then presents the following race condition: CPU0 CPU1 flush_tlb_mm(mm) use_mm(mm) <send-IPI> tsk->active_mm = mm; <IPI> if (tsk->active_mm == mm) // flush TLBs </IPI> switch_mm(old_mm,mm,tsk); Where it is possible the IPI flushed the TLBs for @old_mm, not @mm, because the IPI lands before we actually switched. Avoid this by disabling IRQs across changing ->active_mm and switch_mm(). Of the (SMP) architectures that have IPI based TLB invalidate: Alpha - checks active_mm ARC - ASID specific IA64 - checks active_mm MIPS - ASID specific flush OpenRISC - shoots down world PARISC - shoots down world SH - ASID specific SPARC - ASID specific x86 - N/A xtensa - checks active_mm So at the very least Alpha, IA64 and Xtensa are suspect. On top of this, for scheduler consistency we need at least preemption disabled across changing tsk->mm and doing switch_mm(), which is currently provided by task_lock(), but that's not sufficient for PREEMPT_RT.

mm/shuffle: don't move pages between zones and don't read garbage memmaps
Especially with memory hotplug, we can have offline sections (with a
garbage memmap) and overlapping zones. We have to make sure to only touch
initialized memmaps (online sections managed by the buddy) and that the
zone matches, to not move pages between zones.
To test if this can actually happen, I added a simple
BUG_ON(page_zone(page_i) != page_zone(page_j));
right before the swap. When hotplugging a 256M DIMM to a 4G x86-64 VM and
onlining the first memory block "online_movable" and the second memory
block "online_kernel", it will trigger the BUG, as both zones (NORMAL and
MOVABLE) overlap.
This might result in all kinds of weird situations (e.g., double
allocations, list corruptions, unmovable allocations ending up in the
movable zone).

New code for 5.9:
- Fix some btree block pingponging problems when swapping extents - Redesign the reflink copy loop so that we only run one remapping operation per transaction. This helps us avoid running out of block reservation on highly deduped filesystems. - Take the MMAPLOCK around filemap_map_pages. - Make inode reclaim fully async so that we avoid stalling processes on flushing inodes to disk. - Reduce inode cluster buffer RMW cycles by attaching the buffer to dirty inodes so we won't let go of the cluster buffer when we know we're going to need it soon. - Add some more checks to the realtime bitmap file scrubber. - Don't trip false lockdep warnings in fs freeze. - Remove various redundant lines of code. - Remove unnecessary calls to xfs_perag_{get,put}. - Preserve I_VERSION state across remounts. - Fix an unmount hang due to AIL going to sleep with a non-empty delwri buffer list. - Fix an error in the inode allocation space reservation macro that caused regressions in generic/531. - Fix a potential livelock when dquot flush fails because the dquot buffer is locked. - Fix a miscalculation when reserving inode quota that could cause users to exceed a hardlimit. - Refactor struct xfs_dquot to use native types for incore fields instead of abusing the ondisk struct for this purpose. This will eventually enable proper y2038+ support, but for now it merely cleans up the quota function declarations. - Actually increment the quota softlimit warning counter so that soft failures turn into hard(er) failures when they exceed the softlimit warning counter limits set by the administrator. - Split incore dquot state flags into their own field and namespace, to avoid mixing them with quota type flags. - Create a new quota type flags namespace so that we can make it obvious when a quota function takes a quota type (user, group, project) as an argument. - Rename the ondisk dquot flags field to type, as that more accurately represents what we store in it. - Drop our bespoke memory allocation flags in favor of GFP_*. - Rearrange the xattr functions so that we no longer mix metadata updates and transaction management (e.g. rolling complex transactions) in the same functions. This work will prepare us for atomic xattr operations (itself a prerequisite for directory backrefs) in future release cycles. - Support FS_DAX_FL (aka FS_XFLAG_DAX) via GETFLAGS/SETFLAGS. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEUzaAxoMeQq6m2jMV+H93GTRKtOsFAl8hmOsACgkQ+H93GTRK tOvCbQ//ax1IR0Bdfz0G85ouNqOqjqpKmtjLJWl4tK0e99AtIFFyjyst0BmiPM61 M2ebqrQ4KtwGcnqPMVczxift4MRfsK1T2WmivuF6GpUTJjEcfo/qDjwPgFT7Gdfc gVCKWozFnv7z8cOVmRxP3jQR+r32FMnc4Nf8ZZ4LO2gGAqfDySZKFJXjkywR5ETk rE0BivsXKqldbSA0nibMwmxNIWn+tBE+Bv3rSDAd6ZWEKbBZkrxf5GW+GkBD/xon HT+T8lKFG5F+9kmL+BRhtV2eZkcbAOmP6x6NTX0SZcXlX2BBT7ltBusjal0lK0uh IizqZv5UG6S2cv0j69EbXm3gvXBs+okAGLRtIPAExfWXf/x0JZp6dNbsnwwI0ZSC N1Uy3lAcyF1Wybuf/6w4bMu8zrVcty8wSOD5psL4GXnhvw9c8iASszwGOUnOUH84 jRZYJNE9jsdItjP/5hNANaidPBnapPxWY4nvqJN4H3FjqTQOakE4X2OSB0LREIDp avAFISrlU2dl0AwMHxCDOlv56FkHsIZ8aJmCpGPQdYpGu8jjYWTUYKvUvcjH/NBW aVL7pUgP5r3vIxawS9tJcy1t3t7JDZmC+w5oasmQ0Rsk1r5mTgNrP6xue6rZzaRg wo6mWZvteoWtEZJnT+L4Glx7i1srMj++Dqu24cJ92o/omA+fmr4= =nhPQ -----END PGP SIGNATURE----- Merge tag 'xfs-5.9-merge-7' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux Pull xfs updates from Darrick Wong: "There are quite a few changes in this release, the most notable of which is that we've made inode flushing fully asynchronous, and we no longer block memory reclaim on this. Furthermore, we have fixed a long-standing bug in the quota code where soft limit warnings and inode limits were never tracked properly. Moving further down the line, the reflink control loops have been redesigned to behave more efficiently; and numerous small bugs have been fixed (see below). The xattr and quota code have been extensively refactored in preparation for more new features coming down the line. Finally, the behavior of DAX between ext4 and xfs has been stabilized, which gets us a step closer to removing the experimental tag from that feature. We have a few new contributors this time around. Welcome, all! I anticipate a second pull request next week for a few small bugfixes that have been trickling in, but this is it for big changes. Summary: - Fix some btree block pingponging problems when swapping extents - Redesign the reflink copy loop so that we only run one remapping operation per transaction.

module: Correctly truncate sysfs sections output
The only-root-readable /sys/module/$module/sections/$section files
did not truncate their output to the available buffer size. While most
paths into the kernfs read handlers end up using PAGE_SIZE buffers,
it's possible to get there through other paths (e.g. splice, sendfile).
Actually limit the output to the "count" passed into the read function,
and report it back correctly. *sigh*

powerpc updates for 5.9
- Add support for (optionally) using queued spinlocks & rwlocks. - Support for a new faster system call ABI using the scv instruction on Power9 or later. - Drop support for the PROT_SAO mmap/mprotect flag as it will be unsupported on Power10 and future processors, leaving us with no way to implement the functionality it requests. This risks breaking userspace, though we believe it is unused in practice. - A bug fix for, and then the removal of, our custom stack expansion checking. We now allow stack expansion up to the rlimit, like other architectures. - Remove the remnants of our (previously disabled) topology update code, which tried to react to NUMA layout changes on virtualised systems, but was prone to crashes and other problems. - Add PMU support for Power10 CPUs. - A change to our signal trampoline so that we don't unbalance the link stack (branch return predictor) in the signal delivery path. - Lots of other cleanups, refactorings, smaller features and so on as usual.

RISC-V Patches for the 5.9 Merge Window, Part 1
We have a lot of new kernel features for this merge window: * ARCH_SUPPORTS_ATOMIC_RMW, to allow OSQ locks to be enabled. * The ability to enable NO_HZ_FULL * Support for enabling kcov, kmemleak, stack protector, and VM debugging. * JUMP_LABEL support.

x86/mm/64: Do not dereference non-present PGD entries
The code for preallocate_vmalloc_pages() was written under the
assumption that the p4d_offset() and pud_offset() functions will perform
present checks before dereferencing the parent entries.
This assumption is wrong an leads to a bug in the code which causes the
physical address found in the PGD be used as a page-table page, even if
the PGD is not present.
So the code flow currently is:
pgd = pgd_offset_k(addr);
p4d = p4d_offset(pgd, addr);
if (p4d_none(*p4d))
p4d = p4d_alloc(&init_mm, pgd, addr);
This lacks a check for pgd_none() at least, the correct flow would be:
pgd = pgd_offset_k(addr);
if (pgd_none(*pgd))
p4d = p4d_alloc(&init_mm, pgd, addr);
else
p4d = p4d_offset(pgd, addr);
But this is the same flow that the p4d_alloc() and the pud_alloc()
functions use internally, so there is no need to duplicate them.
Remove the p?d_none() checks from the function and just call into
p4d_alloc() and pud_alloc() to correctly pre-allocate the PGD entries.

thermal: don't make THERMAL_NETLINK 'default y'
We just don't do that. "default y" is for things that are needed for compatibility (when an old feature is made unconditional), or for things that are basically part of the infrastructure of a platform. And it can possibly be used for questions that don't enable code on their own, but are used to enable or disable a whole slew of other questions. A new feature that people aren't using is never 'default y', unless it cures cancer or ends world hunger. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

gfs2: When gfs2_dirty_inode gets a glock error, dump the glock
Before this patch, if function gfs2_dirty_inode got an error when trying to lock the inode glock, it complained, but it didn't say what glock or inode had the problem. In this case, it almost always means that dinode_in found an error with the dinode in the file system. So it makes sense to dump the glock, which tells us the location of the dinode in the file system. That will allow us to analyze the corruption from the metadata.

gfs2: Never call gfs2_block_zero_range with an open transaction
Before this patch, some functions started transactions then they called
gfs2_block_zero_range. However, gfs2_block_zero_range, like writes, can
start transactions, which results in a recursive transaction error.
For example:
do_shrink
trunc_start
gfs2_trans_begin <------------------------------------------------
gfs2_block_zero_range
iomap_zero_range(inode, from, length, NULL, &gfs2_iomap_ops);
iomap_apply ... iomap_zero_range_actor
iomap_begin
gfs2_iomap_begin
gfs2_iomap_begin_write
actor (iomap_zero_range_actor)
iomap_zero
iomap_write_begin
gfs2_iomap_page_prepare
gfs2_trans_begin <------------------------
This patch reorders the callers of gfs2_block_zero_range so that they
only start their transactions after the call. It also adds a BUG_ON to
ensure this doesn't happen again.

perf record: Skip side-band event setup if HAVE_LIBBPF_SUPPORT is not set
We received an error report that perf-record caused 'Segmentation fault'
on a newly system (e.g. on the new installed ubuntu).
(gdb) backtrace

#6 0x00007fad7823c103 in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95
The root cause is, evlist__add_bpf_sb_event() just returns 0 if
HAVE_LIBBPF_SUPPORT is not defined (inline function path). So it will
not create a valid evsel for side-band event.
But perf-record still creates BPF side band thread to process the
side-band event, then the error happpens.
We can reproduce this issue by removing the libelf-dev. e.g.
1. apt-get remove libelf-dev
2. perf record -a -- sleep 1
root@test:~# ./perf record -a -- sleep 1
perf: Segmentation fault

Segmentation fault (core dumped)
To fix this issue,
1. We either install the missing libraries to let HAVE_LIBBPF_SUPPORT
be defined.
e.g. apt-get install libelf-dev and install other related libraries.
2. Use this patch to skip the side-band event setup if HAVE_LIBBPF_SUPPORT
is not set.
Committer notes:
The side band thread is not used just with BPF, it is also used with
--switch-output-event, so narrow the ifdef to the BPF specific part.

Perf tools side uses extended mask to display the platform supported register names (with -I? option) to the user and also send this mask to the kernel to capture the extended registers in each sample. Hence decide the mask value based on the processor version. Currently definitions for `mfspr`, `SPRN_PVR` are part of `arch/powerpc/util/header.c`.

Input: exc3000 - add support to query model and fw_version
Expose model and fw_version via sysfs. Also query the model in probe to make sure, that the I2C communication with the device works before successfully probing the driver. This is a bit complicated, since EETI devices do not have a sync interface. Sending the commands and directly reading does not work. Sending the command and waiting for some time is also not an option, since there might be touch events in the mean time. Last but not least we do not cache the results, since this interface can be used to check the I2C communication is still working as expected.

Input: ims-pcu - return error code rather than -ENOMEM
Currently the assignment of -ENOMEM to error is redundant because error is not being read and -ENOMEM is being hard coded as an error return. Fix this by returning the error code in variable 'error'; this also allows the error code from a failed call to input_register_device to be preserved and returned to the caller rather than just returning a possibly inappropriate -ENOMEM.

TTY/Serial patches for 5.9-rc1
Here is the large set of TTY and Serial driver patches for 5.9-rc1. Lots of bugfixes in here, thanks to syzbot fuzzing for serial and vt and console code. Other highlights include: - much needed vt/vc code cleanup from Jiri Slaby - 8250 driver fixes and additions - various serial driver updates and feature enhancements - locking cleanup for serial/console initializations - other minor cleanups All of these have been in linux-next with no reported issues.

Staging/IIO driver patches for 5.9-rc1
Here is the large set of Staging and IIO driver patches for 5.9-rc1. Lots of churn here, but overall the size increase in lines added is small, while adding a load of new IIO drivers. Major things in here: - lots and lots of IIO new drivers and frameworks added - IIO driver fixes and updates - lots of tiny coding style cleanups for staging drivers - vc04_services major reworks and cleanups We had 3 set of drivers move out of staging in this round as well: - wilc1000 wireless driver moved out of staging - speakup moved out of staging - most USB driver moved out of staging Full details are in the shortlog. All of these have been in linux-next with no reported issues. The last few changes here were to resolve reported linux-next issues, and they seem to have resolved the problems.
