i2c: i2c-qcom-geni: Fix DMA transfer race
When I have KASAN enabled on my kernel and I start stressing the
touchscreen my system tends to hang. The touchscreen is one of the
only things that does a lot of big i2c transfers and ends up hitting
the DMA paths in the geni i2c driver. It appears that KASAN adds
enough delay in my system to tickle a race condition in the DMA setup
code.
When the system hangs, I found that it was running the geni_i2c_irq()
over and over again. It had these:
m_stat = 0x04000080
rx_st = 0x30000011
dm_tx_st = 0x00000000
dm_rx_st = 0x00000000
dma = 0x00000001
Notably we're in DMA mode but are getting M_RX_IRQ_EN and
M_RX_FIFO_WATERMARK_EN over and over again.
Putting some traces in geni_i2c_rx_one_msg() showed that when we
failed we were getting to the start of geni_i2c_rx_one_msg() but were
never executing geni_se_rx_dma_prep().
I believe that the problem here is that we are starting the geni
command before we run geni_se_rx_dma_prep(). If a transfer makes it
far enough before we do that then we get into the state I have
observed. Let's change the order, which seems to work fine.
Although problems were seen on the RX path, code inspection suggests
that the TX should be changed too. Change it as well.

i2c: rcar: always clear ICSAR to avoid side effects
On R-Car Gen2, we get a timeout when reading from the address set in
ICSAR, even though the slave interface is disabled. Clearing it fixes
this situation. Note that Gen3 is not affected.
To reproduce: bind and undbind an I2C slave on some bus, run
'i2cdetect' on that bus.

arm64: vdso32: Fix '--prefix=' value for newer versions of clang
Newer versions of clang only look for $(COMPAT_GCC_TOOLCHAIN_DIR)as [1],
rather than $(COMPAT_GCC_TOOLCHAIN_DIR)$(CROSS_COMPILE_COMPAT)as,
resulting in the following build error:
$ make -skj"$(nproc)" ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- \
CROSS_COMPILE_COMPAT=arm-linux-gnueabi- LLVM=1 O=out/aarch64 distclean \
defconfig arch/arm64/kernel/vdso32/
...
/home/nathan/cbl/toolchains/llvm-binutils/bin/as: unrecognized option '-EL'
clang-12: error: assembler command failed with exit code 1 (use -v to see invocation)
make[3]: *** [arch/arm64/kernel/vdso32/Makefile:181: arch/arm64/kernel/vdso32/note.o] Error 1
...
Adding the value of CROSS_COMPILE_COMPAT (adding notdir to account for a
full path for CROSS_COMPILE_COMPAT) fixes this issue, which matches the
solution done for the main Makefile [2].

i2c: cadence: Clear HOLD bit at correct time in Rx path
There are few issues on Zynq SOC observed in the stress tests causing timeout errors. Even though all the data is received, timeout error is thrown. This is due to an IP bug in which the COMP bit in ISR is not set at end of transfer and completion interrupt is not generated. This bug is seen on Zynq platforms when the following condition occurs: Master read & HOLD bit set & Transfer size register reaches '0'. One workaround is to clear the HOLD bit before the transfer size register reaches '0'. The current implementation checks for this at the start of the loop and also only for less than FIFO DEPTH case (ignoring the equal to case). So clear the HOLD bit when the data yet to receive is less than or equal to the FIFO DEPTH. This avoids the IP bug condition.

btrfs: fix mount failure caused by race with umount
It is possible to cause a btrfs mount to fail by racing it with a slow
umount. The crux of the sequence is generic_shutdown_super not yet
calling sop->put_super before btrfs_mount_root calls btrfs_open_devices.
If that occurs, btrfs_open_devices will decide the opened counter is
non-zero, increment it, and skip resetting fs_devices->total_rw_bytes to
0. From here, mount will call sget which will result in grab_super
trying to take the super block umount semaphore. That semaphore will be
held by the slow umount, so mount will block. Before up-ing the
semaphore, umount will delete the super block, resulting in mount's sget
reliably allocating a new one, which causes the mount path to dutifully
fill it out, and increment total_rw_bytes a second time, which causes
the mount to fail, as we see double the expected bytes.
Here is the sequence laid out in greater detail:
CPU0 CPU1
down_write sb->s_umount
btrfs_kill_super
kill_anon_super(sb)
generic_shutdown_super(sb);
shrink_dcache_for_umount(sb);
sync_filesystem(sb);
evict_inodes(sb); // SLOW
btrfs_mount_root
btrfs_scan_one_device
fs_devices = device->fs_devices
fs_info->fs_devices = fs_devices
// fs_devices-opened makes this a no-op
btrfs_open_devices(fs_devices, mode, fs_type)
s = sget(fs_type, test, set, flags, fs_info);
find sb in s_instances
grab_super(sb);
down_write(&s->s_umount); // blocks
sop->put_super(sb)
// sb->fs_devices->opened == 2; no-op
spin_lock(&sb_lock);
hlist_del_init(&sb->s_instances);
spin_unlock(&sb_lock);
up_write(&sb->s_umount);
return 0;
retry lookup
don't find sb in s_instances (deleted by CPU0)
s = alloc_super
return s;
btrfs_fill_super(s, fs_devices, data)
open_ctree // fs_devices total_rw_bytes improperly set!
btrfs_read_chunk_tree
read_one_dev // increment total_rw_bytes again!!
super_total_bytes < fs_devices->total_rw_bytes // ERROR!!!
To fix this, we clear total_rw_bytes from within btrfs_read_chunk_tree
before the calls to read_one_dev, while holding the sb umount semaphore
and the uuid mutex.
To reproduce, it is sufficient to dirty a decent number of inodes, then
quickly umount and mount.
for i in $(seq 0 500)
do
dd if=/dev/zero of="/mnt/foo/$i" bs=1M count=1
done
umount /mnt/foo&
mount /mnt/foo
does the trick for me.

btrfs: qgroup: fix data leak caused by race between writeback and truncate
[BUG]
When running tests like generic/013 on test device with btrfs quota
enabled, it can normally lead to data leak, detected at unmount time:

BTRFS error (device dm-3): qgroup reserved space leaked
[CAUSE]
In the offending case, the offending operations are:
2/6: writev f2X[269 1 0 0 0 0] [1006997,67,288] 0
2/7: truncate f2X[269 1 0 0 48 1026293] 18388 0
The following sequence of events could happen after the writev():
CPU1 (writeback) | CPU2 (truncate)
-----------------------------------------------------------------
btrfs_writepages() |
|- extent_write_cache_pages() |
|- Got page for 1003520 |
| 1003520 is Dirty, no writeback |
| So (!clear_page_dirty_for_io()) |
| gets called for it |
|- Now page 1003520 is Clean. |
| | btrfs_setattr()
| | |- btrfs_setsize()
| | |- truncate_setsize()
| | New i_size is 18388
|- __extent_writepage() |
| |- page_offset() > i_size |
|- btrfs_invalidatepage() |
|- Page is clean, so no qgroup |
callback executed
This means, the qgroup reserved data space is not properly released in
btrfs_invalidatepage() as the page is Clean.
[FIX]
Instead of checking the dirty bit of a page, call
btrfs_qgroup_free_data() unconditionally in btrfs_invalidatepage().
As qgroup rsv are completely bound to the QGROUP_RESERVED bit of
io_tree, not bound to page status, thus we won't cause double freeing
anyway.

NULL dereference occurs when string that is not ended with space or newline is written to some dpm sysfs interface (for example pp_dpm_sclk). This happens because strsep replaces the tmp with NULL if the delimiter is not present in string, which is then dereferenced by tmp[0].

btrfs: fix double free on ulist after backref resolution failure
At btrfs_find_all_roots_safe() we allocate a ulist and set the **roots
argument to point to it. However if later we fail due to an error returned
by find_parent_nodes(), we free that ulist but leave a dangling pointer in
the **roots argument. Upon receiving the error, a caller of this function
can attempt to free the same ulist again, resulting in an invalid memory
access.
One such scenario is during qgroup accounting:
btrfs_qgroup_account_extents()
--> calls btrfs_find_all_roots() passes &new_roots (a stack allocated
pointer) to btrfs_find_all_roots()
--> btrfs_find_all_roots() just calls btrfs_find_all_roots_safe()
passing &new_roots to it
--> allocates ulist and assigns its address to **roots (which
points to new_roots from btrfs_qgroup_account_extents())
--> find_parent_nodes() returns an error, so we free the ulist
and leave **roots pointing to it after returning
--> btrfs_qgroup_account_extents() sees btrfs_find_all_roots() returned
an error and jumps to the label 'cleanup', which just tries to
free again the same ulist

RDMA/mlx5: Prevent prefetch from racing with implicit destruction
Prefetch work in mlx5_ib_prefetch_mr_work can be queued and able to run
concurrently with destruction of the implicit MR. The num_deferred_work
was intended to serialize this, but there is a race:
CPU0 CPU1
mlx5_ib_free_implicit_mr()
xa_erase(odp_mkeys)
synchronize_srcu()
__xa_erase(implicit_children)
mlx5_ib_prefetch_mr_work()
pagefault_mr()
pagefault_implicit_mr()
implicit_get_child_mr()
xa_cmpxchg()
atomic_dec_and_test(num_deferred_mr)
wait_event(imr->q_deferred_work)
ib_umem_odp_release(odp_imr)
kfree(odp_imr)
At this point in mlx5_ib_free_implicit_mr() the implicit_children list is
supposed to be empty forever so that destroy_unused_implicit_child_mr()
and related are not and will not be running.
Since it is not empty the destroy_unused_implicit_child_mr() flow ends up
touching deallocated memory as mlx5_ib_free_implicit_mr() already tore down the
imr parent.
The solution is to flush out the prefetch wq by driving num_deferred_work
to zero after creation of new prefetch work is blocked.

Majority of changes are for x86 based platforms and their CODEC drivers, in order to address some issues hit by their recent tests and fuzzing.

Change the counter name DLFT_CCERROR to DLFT_CCFINISH on IBM z15. This counter counts completed DEFLATE instructions with exit code 0, 1 or 2. Since exit code 0 means success and exit code 1 or 2 indicate errors, change the counter name to avoid confusion. This counter is incremented each time the DEFLATE instruction completed regardless if an error was detected or not. Fixes: |

copy_xstate_to_kernel: Fix typo which caused GDB regression
This fixes a regression encountered while running the
gdb.base/corefile.exp test in GDB's test suite.
In my testing, the typo prevented the sw_reserved field of struct
fxregs_state from being output to the kernel XSAVES area. Thus the
correct mask corresponding to XCR0 was not present in the core file for
GDB to interrogate, resulting in the following behavior:
[kev@f32-1 gdb]$ ./gdb -q testsuite/outputs/gdb.base/corefile/corefile testsuite/outputs/gdb.base/corefile/corefile.core
Reading symbols from testsuite/outputs/gdb.base/corefile/corefile...
[New LWP 232880]
warning: Unexpected size of section `.reg-xstate/232880' in core file.
With the typo fixed, the test works again as expected.

Third batch of perf tooling fixes for 5.8:
- Update hashmap.h from libbpf and kvm.h from x86's kernel UAPI.
- Set opt->set in libsubcmd's OPT_CALLBACK_SET(). Fixes
'perf record --switch-output-event event-name' usage.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Some of the most recent, experimental distros are failing, fixes will be
provided, but those gcc/clang versions are not yet in general use and some
are related to linking with libllvm, not the default build.

A pile of fixes for x86:
- Fix the I/O bitmap invalidation on XEN PV, which was overlooked in the
recent ioperm/iopl rework. This caused the TSS and XEN's I/O bitmap to
get out of sync.
- Use the proper vectors for HYPERV.
- Make disabling of stack protector for the entry code work with GCC
builds which enable stack protector by default. Removing the option is
not sufficient, it needs an explicit -fno-stack-protector to shut it
off.
- Mark check_user_regs() noinstr as it is called from noinstr code. The
missing annotation causes it to be placed in the text section which
makes it instrumentable.
- Add the missing interrupt disable in exc_alignment_check()
- Fixup a XEN_PV build dependency in the 32bit entry code
- A few fixes to make the Clang integrated assembler happy
- Move EFI stub build to the right place for out of tree builds
- Make prepare_exit_to_usermode() static. It's not longer called from ASM
code.

Two fixes for the timer wheel:
- A timer which is already expired at enqueue time can set the
base->next_expiry value backwards. As a consequence base->clk can be set
back as well. This can lead to timers expiring early. Add a sanity check
to prevent this.
- When a timer is queued with an expiry time beyond the wheel capacity
then it should be queued in the bucket of the last wheel level which is
expiring last. The code adjusts expiry time to the maximum wheel
capacity, which is only correct when the wheel clock is 0. Aside of that
the check whether the delta is larger than wheel capacity does not check
the delta, it checks the expiry value itself. As a result timers can
expire at random.
Fix this by checking the right variable and adjust expiry time so it
becomes base->clock plus capacity which places it into the outmost
bucket in the last wheel level.
