openrisc: Add full instruction cache invalidate functions
Add functions to invalidate all cache lines which we will use for static_key patching. On OpenRISC there is no instruction to invalidate an entire cache so we loop and invalidate cache lines one by one. This is not extremely expensive on OpenRISC as we usually have only a few hundred cache lines. I considered using the invalidate cache page or range functions. However, tracking which ranges need invalidation would have been more expensive than flushing all pages. Cc: stable@vger.kernel.org Signed-off-by: Stafford Horne <shorne@gmail.com> |

openrisc: Cache invalidation cleanup
When working on new cache invalidation functions I noticed these cleanups in the cache initialization code. Remove unused and commented instructions to avoid confusion. Signed-off-by: Stafford Horne <shorne@gmail.com> |

spi: Fixes for v7.0 merge window
There's a relatively large but ultimately simple fix for spidev here which addresses some ABBA races by simplifying down to just using a single lock, it's not clear to me that there was ever any benefit in having the two separate locks in the first place. We also have simple missing error check fix in in the wpcm-fiu driver. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmmXWZkACgkQJNaLcl1U h9CADQf+Kuqhoi1BsUQE8BzCp5QJaOuvihRA6ZlVt12Cw849ovB82xtpmHuiNFnf wIhmgK76lKQEHf93ZyoHy2v8ZNJdpSXyhsg6/oPpp/qmeafJbJ7mPtuUbEzgOnZZ 11iJSEZTfdSCxhPf2Vaf8/vNCKcAGFtbP66VifG+EVjVwTd9kAAvCmeTpxd+lZ33 ire8DW9rUoxxPgBesjz+9BLwzSWxjqd2RCQzTnfLbSk5EG+tu3u2q/BuykZ0VbDx DPFP3GU/wr4IIuxjfTNDDSqBwiEX6p47r+bEYhYZrBZX4bUGYOtO13AmGRtoNYL7 ulGFcs5fEcNEIt8RfQ7YSwRTiPjG8w== =GUCH -----END PGP SIGNATURE----- Merge tag 'spi-fix-v7.0-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi fixes from Mark Brown: "There's a relatively large but ultimately simple fix for spidev here which addresses some ABBA races by simplifying down to just using a single lock, it's not clear to me that there was ever any benefit in having the two separate locks in the first place.

Tracing fixes for 7.0:
- Fix possible dereference of uninitialized pointer When validating the persistent ring buffer on boot up, if the first validation fails, a reference to "head_page" is performed in the error path, but it skips over the initialization of that variable. Move the initialization before the first validation check. - Fix use of event length in validation of persistent ring buffer On boot up, the persistent ring buffer is checked to see if it is valid by several methods. One being to walk all the events in the memory location to make sure they are all valid. The length of the event is used to move to the next event. This length is determined by the data in the buffer. If that length is corrupted, it could possibly make the next event to check located at a bad memory location. Validate the length field of the event when doing the event walk. - Fix function graph on archs that do not support use of ftrace_ops When an architecture defines HAVE_DYNAMIC_FTRACE_WITH_ARGS, it means that its function graph tracer uses the ftrace_ops of the function tracer to call its callbacks. This allows a single registered callback to be called directly instead of checking the callback's meta data's hash entries against the function being traced. For architectures that do not support this feature, it must always call the loop function that tests each registered callback (even if there's only one). The loop function tests each callback's meta data against its hash of functions and will call its callback if the function being traced is in its hash map. The issue was that there was no check against this and the direct function was being called even if the architecture didn't support it. This meant that if function tracing was enabled at the same time as a callback was registered with the function graph tracer, its callback would be called for every function that the function tracer also traced, even if the callback's meta data only wanted to be called back for a small subset of functions. Prevent the direct calling for those architectures that do not support it. - Fix references to trace_event_file for hist files The hist files used event_file_data() to get a reference to the associated trace_event_file the histogram was attached to. This would return a pointer even if the trace_event_file is about to be freed (via RCU). Instead it should use the event_file_file() helper that returns NULL if the trace_event_file is marked to be freed so that no new references are added to it. - Wake up hist poll readers when an event is being freed When polling on a hist file, the task is only awoken when a hist trigger is triggered. This means that if an event is being freed while there's a task waiting on its hist file, it will need to wait until the hist trigger occurs to wake it up and allow the freeing to happen. Note, the event will not be completely freed until all references are removed, and a hist poller keeps a reference. But it should still be woken when the event is being freed. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCaZd4ExQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qqX5AP4powfnNnRfLSKH9idhTp+ltmJ+9roy L7kWTr/z20S2VQEAk331PNZ32uZu+/ZUETYpgtEx4SbRGZFehTBv1ddjfw4= =TWj5 -----END PGP SIGNATURE----- Merge tag 'trace-v7.0-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix possible dereference of uninitialized pointer When validating the persistent ring buffer on boot up, if the first validation fails, a reference to "head_page" is performed in the error path, but it skips over the initialization of that variable.

eCryptfs fixes for 7.0-rc1
The set of eCryptfs patches for the 7.0-rc1 merge window consists of
cleanups that are not intended to have any functional changes:
- Comment typo fixes
- Removal of an unused function declaration
- Use strscpy() instead of the deprecated strcpy()
- Use string copying helpers instead of memcpy() and manually
terminating strings
The patches have all spent time in linux-next and they do not regress
the tests in the ecryptfs-utils tree.

PCI: dwc: ep: Always clear IB maps on BAR update
dw_pcie_ep_set_bar() currently tears down existing inbound mappings only
when either the previous or the new struct pci_epf_bar uses submaps
(num_submap != 0). If both the old and new mappings are BAR Match Mode,
reprogramming the same ATU index is sufficient, so no explicit teardown
was needed.
However, some callers may reuse the same struct pci_epf_bar instance and
update it in place before calling set_bar() again. In that case
ep_func->epf_bar[bar] and the passed-in epf_bar can point to the same
object, so we cannot reliably distinguish BAR Match Mode -> BAR Match Mode
from Address Match Mode -> BAR Match Mode. As a result, the conditional
teardown based on num_submap becomes unreliable and existing inbound maps
may be left active.
Call dw_pcie_ep_clear_ib_maps() unconditionally before reprogramming the
BAR so that in-place updates are handled correctly.
This introduces a behavioral change in a corner case: if a BAR
reprogramming attempt fails (especially for the long-standing BAR Match
Mode -> BAR Match Mode update case), the previously programmed inbound
mapping will already have been torn down. This should be acceptable, since
the caller observes the error and should not use the BAR for any real
transactions in that case.
While at it, document that the existing update parameter check is
best-effort for in-place updates.

PCI: dwc: ep: Return after clearing BAR-match inbound mapping
dw_pcie_ep_clear_ib_maps() first checks whether the inbound mapping for a BAR is in BAR Match Mode (tracked via ep_func->bar_to_atu[bar]). Once found, the iATU region is disabled and the bookkeeping is cleared. BAR Match Mode and Address Match Mode mappings are mutually exclusive for a given BAR, so there is nothing left for the Address Match Mode teardown path to do after the BAR Match Mode mapping has been removed. Return early after clearing the BAR Match Mode mapping to avoid running the Address Match Mode teardown path. This makes the helper's intention explicit and helps detect incorrect use of pci_epc_set_bar().

PCI: Account fully optional bridge windows correctly
pbus_size_mem_optional() adds dev_res->add_size of a bridge window into
children_add_size when the window has a non-optional part. However, if the
bridge window is fully optional, only r_size is added (which is zero for
such a window).
Also, a second dev_res entry will be added by pci_dev_res_add_to_list()
into realloc_head for the bridge window (resulting in triggering the
realloc_head-must-be-fully-consumed sanity check after a single pass of the
resource assignment algorithm):
WARNING: drivers/pci/setup-bus.c:2153 at pci_assign_unassigned_root_bus_resources+0xa5/0x260
Correct these problems by always adding dev_res->add_size for bridge
windows and not calling pci_dev_res_add_to_list() if the dev_res entry
exists.

tracing: Wake up poll waiters for hist files when removing an event
The event_hist_poll() function attempts to verify whether an event file is
being removed, but this check may not occur or could be unnecessarily
delayed. This happens because hist_poll_wakeup() is currently invoked only
from event_hist_trigger() when a hist command is triggered. If the event
file is being removed, no associated hist command will be triggered and a
waiter will be woken up only after an unrelated hist command is triggered.
Fix the issue by adding a call to hist_poll_wakeup() in
remove_event_file_dir() after setting the EVENT_FILE_FL_FREED flag. This
ensures that a task polling on a hist file is woken up and receives
EPOLLERR.

tracing: Fix checking of freed trace_event_file for hist files
The event_hist_open() and event_hist_poll() functions currently retrieve
a trace_event_file pointer from a file struct by invoking
event_file_data(), which simply returns file->f_inode->i_private. The
functions then check if the pointer is NULL to determine whether the event
is still valid. This approach is flawed because i_private is assigned when
an eventfs inode is allocated and remains set throughout its lifetime.
Instead, the code should call event_file_file(), which checks for
EVENT_FILE_FL_FREED. Using the incorrect access function may result in the
code potentially opening a hist file for an event that is being removed or
becoming stuck while polling on this file.
Correct the access method to event_file_file() in both functions.

fgraph: Do not call handlers direct when not using ftrace_ops
The function graph tracer was modified to us the ftrace_ops of the
function tracer. This simplified the code as well as allowed more features
of the function graph tracer.
Not all architectures were converted over as it required the
implementation of HAVE_DYNAMIC_FTRACE_WITH_ARGS to implement. For those
architectures, it still did it the old way where the function graph tracer
handle was called by the function tracer trampoline. The handler then had
to check the hash to see if the registered handlers wanted to be called by
that function or not.
In order to speed up the function graph tracer that used ftrace_ops, if
only one callback was registered with function graph, it would call its
function directly via a static call.
Now, if the architecture does not support the use of using ftrace_ops and
still has the ftrace function trampoline calling the function graph
handler, then by doing a direct call it removes the check against the
handler's hash (list of functions it wants callbacks to), and it may call
that handler for functions that the handler did not request calls for.
On 32bit x86, which does not support the ftrace_ops use with function
graph tracer, it shows the issue:
~# trace-cmd start -p function -l schedule
~# trace-cmd show
# tracer: function_graph
#
# CPU DURATION FUNCTION CALLS
# | | | | | | |
2) * 11898.94 us | schedule();
3) # 1783.041 us | schedule();
1) | schedule() {
------------------------------------------
1) bash-8369 => kworker-7669
------------------------------------------
1) | schedule() {
------------------------------------------
1) kworker-7669 => bash-8369
------------------------------------------
1) + 97.004 us | }
1) | schedule() {
[..]
Now by starting the function tracer is another instance:
~# trace-cmd start -B foo -p function
This causes the function graph tracer to trace all functions (because the
function trace calls the function graph tracer for each on, and the
function graph trace is doing a direct call):
~# trace-cmd show
# tracer: function_graph
#
# CPU DURATION FUNCTION CALLS
# | | | | | | |
1) 1.669 us | } /* preempt_count_sub */
1) + 10.443 us | } /* _raw_spin_unlock_irqrestore */
1) | tick_program_event() {
1) | clockevents_program_event() {
1) 1.044 us | ktime_get();
1) 6.481 us | lapic_next_event();
1) + 10.114 us | }
1) + 11.790 us | }
1) ! 181.223 us | } /* hrtimer_interrupt */
1) ! 184.624 us | } /* __sysvec_apic_timer_interrupt */
1) | irq_exit_rcu() {
1) 0.678 us | preempt_count_sub();
When it should still only be tracing the schedule() function.
To fix this, add a macro FGRAPH_NO_DIRECT to be set to 0 when the
architecture does not support function graph use of ftrace_ops, and set to
1 otherwise. Then use this macro to know to allow function graph tracer to
call the handlers directly or not.

tracing: ring-buffer: Fix to check event length before using
Check the event length before adding it for accessing next index in
rb_read_data_buffer(). Since this function is used for validating
possibly broken ring buffers, the length of the event could be broken.
In that case, the new event (e + len) can point a wrong address.
To avoid invalid memory access at boot, check whether the length of
each event is in the possible range before using it.

ring-buffer: Fix possible dereference of uninitialized pointer
There is a pointer head_page in rb_meta_validate_events() which is not
initialized at the beginning of a function. This pointer can be dereferenced
if there is a failure during reader page validation. In this case the control
is passed to "invalid" label where the pointer is dereferenced in a loop.
To fix the issue initialize orig_head and head_page before calling
rb_validate_buffer.

KVM: arm64: vgic: Handle const qualifier from gic_kvm_info allocation type
In preparation for making the kmalloc family of allocators type aware, we need to make sure that the returned type from the allocation matches the type of the variable being assigned. (Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type is "struct gic_kvm_info", but the returned type, while matching, is const qualified. To get them exactly matching, just use the dereferenced pointer for the sizeof().

net/mlx5e: Fix deadlocks between devlink and netdev instance locks
In the mentioned "Fixes" commit, various work tasks triggering devlink
health reporter recovery were switched to use netdev_trylock to protect
against concurrent tear down of the channels being recovered. But this
had the side effect of introducing potential deadlocks because of
incorrect lock ordering.
The correct lock order is described by the init flow:
probe_one -> mlx5_init_one (acquires devlink lock)
-> mlx5_init_one_devl_locked -> mlx5_register_device
-> mlx5_rescan_drivers_locked -...-> mlx5e_probe -> _mlx5e_probe
-> register_netdev (acquires rtnl lock)
-> register_netdevice (acquires netdev lock)
=> devlink lock -> rtnl lock -> netdev lock.
But in the current recovery flow, the order is wrong:
mlx5e_tx_err_cqe_work (acquires netdev lock)
-> mlx5e_reporter_tx_err_cqe -> mlx5e_health_report
-> devlink_health_report (acquires devlink lock => boom!)
-> devlink_health_reporter_recover
-> mlx5e_tx_reporter_recover -> mlx5e_tx_reporter_recover_from_ctx
-> mlx5e_tx_reporter_err_cqe_recover
The same pattern exists in:
mlx5e_reporter_rx_timeout
mlx5e_reporter_tx_ptpsq_unhealthy
mlx5e_reporter_tx_timeout
Fix these by moving the netdev_trylock calls from the work handlers
lower in the call stack, in the respective recovery functions, where
they are actually necessary.

net/mlx5e: MACsec, add ASO poll loop in macsec_aso_set_arm_event
The macsec_aso_set_arm_event function calls mlx5_aso_poll_cq once
without a retry loop. If the CQE is not immediately available after
posting the WQE, the function fails unnecessarily.
Use read_poll_timeout() to poll 3-10 usecs for CQE, consistent with
other ASO polling code paths in the driver.

net/mlx5: Fix misidentification of write combining CQE during poll loop
The write combining completion poll loop uses usleep_range() which can
sleep much longer than requested due to scheduler latency. Under load,
we witnessed a 20ms+ delay until the process was rescheduled, causing
the jiffies based timeout to expire while the thread is sleeping.
The original do-while loop structure (poll, sleep, check timeout) would
exit without a final poll when waking after timeout, missing a CQE that
arrived during sleep.
Instead of the open-coded while loop, use the kernel's poll_timeout_us()
which always performs an additional check after the sleep expiration,
and is less error-prone.
Note: poll_timeout_us() doesn't accept a sleep range, by passing 10
sleep_us the sleep range effectively changes from 2-10 to 3-10 usecs.

net/mlx5: Fix multiport device check over light SFs
Driver is using num_vhca_ports capability to distinguish between
multiport master device and multiport slave device. num_vhca_ports is a
capability the driver sets according to the MAX num_vhca_ports
capability reported by FW. On the other hand, light SFs doesn't set the
above capbility.
This leads to wrong results whenever light SFs is checking whether he is
a multiport master or slave.
Therefore, use the MAX capability to distinguish between master and
slave devices.
