2022-09-14pinctrl: ocelot: Fix interrupt controllerHoratiu Vultur1-14/+97
When an external device generated a level based interrupt then the interrupt controller could miss the interrupt. The reason is that the interrupt controller can detect only link changes. In the following example, if there is a PHY that generates an interrupt then the following would happen. The GPIO detected that the interrupt line changed, and then the 'ocelot_irq_handler' was called. Here it detects which GPIO line saw the change and for that will call the following: 1. irq_mask 2. phy interrupt routine 3. irq_eoi 4. irq_unmask And this works fine for simple cases, but if the PHY generates many interrupts, for example when doing PTP timestamping, then the following could happen. Again the function 'ocelot_irq_handler' will be called and then from here the following could happen: 1. irq_mask 2. phy interrupt routine 3. irq_eoi 4. irq_unmask Right before step 3(irq_eoi), the PHY will generate another interrupt. Now the interrupt controller will acknowledge the change in the interrupt line. So we miss the interrupt. A solution will be to use 'handle_level_irq' instead of 'handle_fasteoi_irq', because for this will change routine order of handling the interrupt. 1. irq_mask 2. irq_ack 3. phy interrupt routine 4. irq_unmask And now if the PHY will generate a new interrupt before irq_unmask, the interrupt controller will detect this because it already acknowledge the change in interrupt line at step 2(irq_ack). But this is not the full solution because there is another issue. In case there are 2 PHYs that share the interrupt line. For example phy1 generates an interrupt, then the following can happen: 1.irq_mask 2.irq_ack 3.phy0 interrupt routine 4.phy1 interrupt routine 5.irq_unmask In case phy0 will generate an interrupt while clearing the interrupt source in phy1, then the interrupt line will be kept down by phy0. So the interrupt controller will not see any changes in the interrupt line. The solution here is to update 'irq_unmask' such that it can detect if the interrupt line is still active or not. And if it is active then call again the procedure to clear the interrupts. But we don't want to do it every time, only if we know that the interrupt controller has not seen already that the interrupt line has changed. While at this, add support also for IRQ_TYPE_LEVEL_LOW.

2022-09-14gpio: mt7621: Make the irqchip immutableSergio Paracuellos1-6/+15
Commit 6c846d026d49 ("gpio: Don't fiddle with irqchips marked as immutable") added a warning to indicate if the gpiolib is altering the internals of irqchips. Following this change the following warnings are now observed for the mt7621 driver: gpio gpiochip0: (1e000600.gpio-bank0): not an immutable chip, please consider fixing it! gpio gpiochip1: (1e000600.gpio-bank1): not an immutable chip, please consider fixing it! gpio gpiochip2: (1e000600.gpio-bank2): not an immutable chip, please consider fixing it!

2022-09-13drm/amd/display: Mark dml30's UseMinimumDCFCLK() as noinline for stack usageNathan Chancellor1-2/+1
This function consumes a lot of stack space and it blows up the size of dml30_ModeSupportAndSystemConfigurationFull() with clang: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3542:6: error: stack frame size (2200) exceeds limit (2048) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than] void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib) ^ 1 error generated. Commit a0f7e7f759cf ("drm/amd/display: fix i386 frame size warning") aimed to address this for i386 but it did not help x86_64. To reduce the amount of stack space that dml30_ModeSupportAndSystemConfigurationFull() uses, mark UseMinimumDCFCLK() as noinline, using the _for_stack variant for documentation. While this will increase the total amount of stack usage between the two functions (1632 and 1304 bytes respectively), it will make sure both stay below the limit of 2048 bytes for these files. The aforementioned change does help reduce UseMinimumDCFCLK()'s stack usage so it should not be reverted in favor of this change.

2022-09-13Revert "fs/exec: allow to unshare a time namespace on vfork+exec"Andrei Vagin3-13/+2
This reverts commit 133e2d3e81de5d9706cab2dd1d52d231c27382e5. Alexey pointed out a few undesirable side effects of the reverted change. First, it doesn't take into account that CLONE_VFORK can be used with CLONE_THREAD. Second, a child process doesn't enter a target time name-space, if its parent dies before the child calls exec. It happens because the parent clears vfork_done. Eric W. Biederman suggests installing a time namespace as a task gets a new mm. It includes all new processes cloned without CLONE_VM and all tasks that call exec(). This is an user API change, but we think there aren't users that depend on the old behavior.

2022-09-13btrfs: zoned: wait for extent buffer IOs before finishing a zoneNaohiro Aota1-2/+38
Before sending REQ_OP_ZONE_FINISH to a zone, we need to ensure that ongoing IOs already finished. Or, we will see a "Zone Is Full" error for the IOs, as the ZONE_FINISH command makes the zone full. We ensure that with btrfs_wait_block_group_reservations() and btrfs_wait_ordered_roots() for a data block group. And, for a metadata block group, the comparison of alloc_offset vs meta_write_pointer mostly ensures IOs for the allocated region already sent. However, there still can be a little time frame where the IOs are sent but not yet completed. Introduce wait_eb_writebacks() to ensure such IOs are completed for a metadata block group. It walks the buffer_radix to find extent buffers in the block group and calls wait_on_extent_buffer_writeback() on them.

We try to create an inline extent for them, but we fail when trying to insert the inline extent with -ENOSPC (at cow_file_range_inline()) - since this is not critical, we fallback to non-inline mode (back to cow_file_range()), reserve extents, create extent maps and create the ordered extents; 3) An unmount starts, enters close_ctree(); 4) The async reclaim task is flushing stuff, entering the flush states one by one, until it reaches RUN_DELAYED_IPUTS. There it runs all current delayed iputs. After running the delayed iputs and before calling btrfs_wait_on_delayed_iputs(), one or more ordered extents complete, and btrfs_add_delayed_iput() is called for each one through btrfs_finish_ordered_io() -> btrfs_put_ordered_extent(). This results in bumping fs_info->nr_delayed_iputs from 0 to some positive value. So the async reclaim task blocks at btrfs_wait_on_delayed_iputs() waiting for fs_info->nr_delayed_iputs to become 0; 5) The current transaction is committed by the transaction kthread, we then start unpinning extents and end up calling btrfs_try_granting_tickets() through unpin_extent_range(), since we released some space. This results in satisfying the ticket created by the cleaner kthread at step 1, waking up the cleaner kthread; 6) At close_ctree() we ask the cleaner kthread to park; 7) The cleaner kthread starts the transaction, deletes the unused block group, and then calls kthread_should_park(), which returns true, so it parks. And at this point we have the delayed iputs added by the completion of the ordered extents still pending; 8) Then later at close_ctree(), when we call: cancel_work_sync(&fs_info->async_reclaim_work); We hang forever, since the cleaner was parked and no one else can run delayed iputs after that, while the reclaim task is waiting for the remaining delayed iputs to be completed. Fix this by waiting for all ordered extents to complete and running the delayed iputs before attempting to stop the async reclaim tasks. Note that we can not wait for ordered extents with btrfs_wait_ordered_roots() (or other similar functions) because that waits for the BTRFS_ORDERED_COMPLETE flag to be set on an ordered extent, but the delayed iput is added after that, when doing the final btrfs_put_ordered_extent(). So instead wait for the work queues used for executing ordered extent completion to be empty, which works because we do the final put on an ordered extent at btrfs_finish_ordered_io() (while we are in the unmount context).

2022-09-13btrfs: fix hang during unmount when stopping block group reclaim workerFilipe Manana1-6/+11
During early unmount, at close_ctree(), we try to stop the block group reclaim task with cancel_work_sync(), but that may hang if the block group reclaim task is currently at btrfs_relocate_block_group() waiting for the flag BTRFS_FS_UNFINISHED_DROPS to be cleared from fs_info->flags. During unmount we only clear that flag later, after trying to stop the block group reclaim task. Fix that by clearing BTRFS_FS_UNFINISHED_DROPS before trying to stop the block group reclaim task and after setting BTRFS_FS_CLOSING_START, so that if the reclaim task is waiting on that bit, it will stop immediately after being woken, because it sees the filesystem is closing (with a call to btrfs_fs_closing()), and then returns immediately with -EINTR.
