arm64/kvm: disable access to AMU registers from kvm guests
Access to the AMU counters should be disabled by default in kvm guests, as information from the counters might reveal activity in other guests or activity on the host. Therefore, disable access to AMU registers from EL0 and EL1 in kvm guests by: - Hiding the presence of the extension in the feature register (SYS_ID_AA64PFR0_EL1) on the VCPU. - Disabling access to the AMU registers before switching to the guest. - Trapping accesses and injecting an undefined instruction into the guest.

arm64: trap to EL1 accesses to AMU counters from EL0
The activity monitors extension is an optional extension introduced by the ARMv8.4 CPU architecture. In order to access the activity monitors counters safely, if desired, the kernel should detect the presence of the extension through the feature register, and mediate the access. Therefore, disable direct accesses to activity monitors counters from EL0 (userspace) and trap them to EL1 (kernel). To be noted that the ARM64_AMU_EXTN kernel config does not have an effect on this code. Given that the amuserenr_el0 resets to an UNKNOWN value, setting the trap of EL0 accesses to EL1 is always attempted for safety and security considerations. Therefore firmware should still ensure accesses to AMU registers are not trapped in EL2/EL3 as this code cannot be bypassed if the CPU implements the Activity Monitors Unit.

Pull btrfs fixes from David Sterba:
"These are fixes that were found during testing with help of error
injection, plus some other stable material.
There's a fixup to patch added to rc1 causing locking in wrong context
warnings, tests found one more deadlock scenario. The patches are
tagged for stable, two of them now in the queue but we'd like all
three released at the same time.
I'm not happy about fixes to fixes in such a fast succession during

Two fixes for the irq core code which are follow ups to the recent MSI
fixes: - The WARN_ON which was put into the MSI setaffinity callback for paranoia reasons actually triggered via a callchain which escaped when all the possible ways to reach that code were analyzed. The proc/irq/$N/*affinity interfaces have a quirk which came in when ALPHA moved to the generic interface: In case that the written affinity mask does not contain any online CPU it calls into ALPHAs magic auto affinity setting code. A few years later this mechanism was also made available to x86 for no good reasons and in a way which circumvents all sanity checks for interrupts which cannot have their affinity set from process context on X86 due to the way the X86 interrupt delivery works. It would be possible to make this work properly, but there is no point in doing so. If the interrupt is not yet started then the affinity setting has no effect and if it is started already then it is already assigned to an online CPU so there is no point to randomly move it to some other CPU. Just return EINVAL as the code has done before that change forever. - The new MSI quirk bit in the irq domain flags turned out to be already occupied, which escaped the author and the reviewers because the already in use bits were 0,6,2,3,4,5 listed in that order. That bit 6 was simply overlooked because the ordering was straight forward linear otherwise. So the new bit ended up being a duplicate. Fix it up by switching the oddball 6 to the obvious 1. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl5Rh+sTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoQ8gD/0aO/tFJrRLmcSlS5r8r70dtHMHIhcq L6bUkg0GKsud6oLVFEhU43K7aWXZkTEqm1bIjX9x0FnMHIYsASmkHyloP/8OBxoA VOG6Q1THxklge/YLBLz7I2NbZNKs/w+WkRKl63FNV9LmdtxtQblYc67CkaQVXiwC tHuijaKOwT/t4V0+HNRVX15FApiDWOSguwcDNigUwk03Uo+hmJsPXuGtJfvyVAf6 Oa00sbvy/XV3qNr2Zm01Pb4osL4FOwCcGuyoeXMZqSvlRbxgT2qz0TzYObqKzZb5 pvZj7coaxKSimNZsVFQ6mluCp9IvFpZOnp1FXcFrzbbFPxEr0G/IMWgVmgf2s3w/ 8XjFCuF33J4mVz36/HYzR2ieH5FsVcGJQR96ZOHArONmszmbun7D7fC3j8RJlkKC 9QpYDcHK17xbLdhR8YanEIDl5QQT/C/qEOdLWrgON7uWEZLs5Y+u39x479MfknyV fYQqi7CC6qUTxQhrt29puaWy8WQvrG4GzWV+vS9d+8v0FIK2KcbA66p/c7UioV3r F9PhxfneSYjswvLhAPmJCM4PSYWvrYZcoGkT+/OzmPXcm+r+Tg4Stgac0EVmhvq5 rBpenELnSuK1MGiFXzL0DKlyNJhpj+UdeAuCoUzConfBMpMwQdvPXpmnT73CQtRb pOgBI4qB3YgP4Q== =jvVI -----END PGP SIGNATURE----- Merge tag 'irq-urgent-2020-02-22' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq fixes from Thomas Gleixner: "Two fixes for the irq core code which are follow ups to the recent MSI fixes: - The WARN_ON which was put into the MSI setaffinity callback for paranoia reasons actually triggered via a callchain which escaped when all the possible ways to reach that code were analyzed.

ext4: fix mount failure with quota configured as module
When CONFIG_QFMT_V2 is configured as a module, the test in
ext4_feature_set_ok() fails and so mount of filesystems with quota or
project features fails. Fix the test to use IS_ENABLED macro which
works properly even for modules.

jbd2: fix ocfs2 corrupt when clearing block group bits
I found a NULL pointer dereference in ocfs2_block_group_clear_bits(). The running environment: kernel version: 4.19 A cluster with two nodes, 5 luns mounted on two nodes, and do some file operations like dd/fallocate/truncate/rm on every lun with storage network disconnection. The fallocate operation on dm-23-45 caused an null pointer dereference.

The bh2jh(group_bh) can be removed after ocfs2_journal_access_gd() and before call "bh2jh(group_bh)->b_committed_data". So, we should move is_handle_aborted() check from do_get_write_access() into jbd2_journal_get_undo_access() and jbd2_journal_get_write_access() before the call to jbd2_write_access_granted().

ext4: fix race between writepages and enabling EXT4_EXTENTS_FL
If EXT4_EXTENTS_FL is set on an inode while ext4_writepages() is running
on it, the following warning in ext4_add_complete_io() can be hit:
WARNING: CPU: 1 PID: 0 at fs/ext4/page-io.c:234 ext4_put_io_end_defer+0xf0/0x120
Here's a minimal reproducer (not 100% reliable) (root isn't required):
while true; do
sync
done &
while true; do
rm -f file
touch file
chattr -e file
echo X >> file
chattr +e file
done
The problem is that in ext4_writepages(), ext4_should_dioread_nolock()
(which only returns true on extent-based files) is checked once to set
the number of reserved journal credits, and also again later to select
the flags for ext4_map_blocks() and copy the reserved journal handle to
ext4_io_end::handle. But if EXT4_EXTENTS_FL is being concurrently set,
the first check can see dioread_nolock disabled while the later one can
see it enabled, causing the reserved handle to unexpectedly be NULL.
Since changing EXT4_EXTENTS_FL is uncommon, and there may be other races
related to doing so as well, fix this by synchronizing changing
EXT4_EXTENTS_FL with ext4_writepages() via the existing
s_writepages_rwsem (previously called s_journal_flag_rwsem).
This was originally reported by syzbot without a reproducer at
https://syzkaller.appspot.com/bug?extid=2202a584a00fffd19fbf,
but now that dioread_nolock is the default I also started seeing this
when running syzkaller locally.

ext4: fix potential race between s_flex_groups online resizing and access
During an online resize an array of s_flex_groups structures gets replaced so it can get enlarged. If there is a concurrent access to the array and this memory has been reused then this can lead to an invalid memory access. The s_flex_group array has been converted into an array of pointers rather than an array of structures. This is to ensure that the information contained in the structures cannot get out of sync during a resize due to an accessor updating the value in the old structure after it has been copied but before the array pointer is updated. Since the structures them- selves are no longer copied but only the pointers to them this case is mitigated.

The change to brk() is necessary to fix a nasty user-visible regression in malloc(), but we tightened up mmap() and mremap() at the same time because they also allow the user to create virtual aliases by accident. It's much less likely than brk() to matter in practice, but enforcing the principle of "don't permit the creation of mappings using tagged addresses" leads to a straightforward ABI without having to worry about the "but what if a crazy program did foo?" aspect of things.

lib/stackdepot.c: fix global out-of-bounds in stack_slabs
Walter Wu has reported a potential case in which init_stack_slab() is
called after stack_slabs[STACK_ALLOC_MAX_SLABS - 1] has already been
initialized. In that case init_stack_slab() will overwrite
stack_slabs[STACK_ALLOC_MAX_SLABS], which may result in a memory
corruption.

mm/sparsemem: pfn_to_page is not valid yet on SPARSEMEM
When we use SPARSEMEM instead of SPARSEMEM_VMEMMAP, pfn_to_page()
doesn't work before sparse_init_one_section() is called.
This leads to a crash when hotplug memory:
BUG: unable to handle page fault for address: 0000000006400000

We should use memmap as it did.
On x86 the impact is limited to x86_32 builds, or x86_64 configurations
that override the default setting for SPARSEMEM_VMEMMAP.
Other memory hotplug archs (arm64, ia64, and ppc) also default to
SPARSEMEM_VMEMMAP=y.

lib/string.c: update match_string() doc-strings with correct behavior
There were a few attempts at changing behavior of the match_string() helpers (i.e. 'match_string()' & 'sysfs_match_string()'), to change & extend the behavior according to the doc-string. But the simplest approach is to just fix the doc-strings. The current behavior is fine as-is, and some bugs were introduced trying to fix it. As for extending the behavior, new helpers can always be introduced if needed. The match_string() helpers behave more like 'strncmp()' in the sense that they go up to n elements or until the first NULL element in the array of strings. This change updates the doc-strings with this info.

scripts/get_maintainer.pl: deprioritize old Fixes: addresses
Recently, I found that get_maintainer was causing me to send emails to
the old addresses for maintainers. Since I usually just trust the
output of get_maintainer to know the right email address, I didn't even
look carefully and fired off two patch series that went to the wrong
place. Oops.
The problem was introduced recently when trying to add signatures from
Fixes. The problem was that these email addresses were added too early
in the process of compiling our list of places to send. Things added to
the list earlier are considered more canonical and when we later added
maintainer entries we ended up deduplicating to the old address.
Here are two examples using mainline commits (to make it easier to
replicate) for the two maintainers that I messed up recently:
$ git format-patch d8549bcd0529~..d8549bcd0529
$ ./scripts/get_maintainer.pl 0001-clk-Add-clk_hw*.patch | grep Boyd
Stephen Boyd <sboyd@codeaurora.org>...
$ git format-patch 6d1238aa3395~..6d1238aa3395
$ ./scripts/get_maintainer.pl 0001-arm64-dts-qcom-qcs404*.patch | grep Andy
Andy Gross <andy.gross@linaro.org>
Let's move the adding of addresses from Fixes: to the end since the
email addresses from these are much more likely to be older.
After this patch the above examples get the right addresses for the two
examples.

selftests/vm: add missed tests in run_vmtests
The commits introducing 'mlock-random-test'[1], 'map_fiex_noreplace'[2], and 'thuge-gen'[3] have not added those in the 'run_vmtests' script and thus the 'run_tests' command of kselftests doesn't run those. This commit adds those in the script. 'gup_benchmark' and 'transhuge-stress' are also not included in the 'run_vmtests', but this commit does not add those because those are for performance measurement rather than pass/fail tests.

y2038: hide timeval/timespec/itimerval/itimerspec types
There are no in-kernel users remaining, but there may still be users that include linux/time.h instead of sys/time.h from user space, so leave the types available to user space while hiding them from kernel space. Only the __kernel_old_* versions of these types remain now.
