2022-05-22habanalabs: don't print normal reset operationsOded Gabbay
Only a hard-reset is an unexpected event which should be notify in the kernel log. Other resets are normal operations and therefore we should not pollute the log with them. Signed-off-by: Oded Gabbay <ogabbay@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2022-05-22habanalabs: change a reset print to debug levelOded Gabbay
Currently we have two reset prints per reset. One is in the common code and one in each asic-specific file. We can change the asic-specific message to be debug only as we can know the type of reset being done according to the print in the common code, which is also easier to maintain.

When Gaudi device is secured the monitors data in the configuration space is blocked from PCI access. As we need to enable user to get sync-manager monitors registers when debugging, this patch adds a debugfs that dumps the information to a binary file (blob).

2022-05-22habanalabs: unified memory manager infrastructureYuri Nudelman
This is a part of overall refactoring attempt to separate nic and the core drivers. Currently, there are 4 different flows, that contain very similar code. These are the ts, nic, hwblocks and cb alloc/map flows. The similar aspect of all these flows is that they all contain a central store, with memory buffers inside, supporting the following set of operations: - Allocate buffer and return handle - Get buffer from the store with handle - Put the buffer (last put releases the buffer) - Map the buffer to the user This patch contains a generic data structure used to implement the above memory buffer store interface. Conversion of the existing code to use the new data structure will follow.

2022-05-22habanalabs: replace usage of found with dedicated list iterator variableJakob Koschel
To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean [1]. This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.

2022-05-22habanalabs/gaudi: avoid resetting max power in hard resetTomer Tayar
The default max power is deduced from the card type value in the CPU-CP info. This value is then set in the max power variable of the device structure. Getting the CPU-CP info is done as part of the late init phase which is called also during reset. This means that a max power value which is modified via sysfs will be reset during hard reset back to the default value. As the max power is updated in any case during device init in hl_sysfs_init(), this setting in late init can be removed, and the overriding during reset is thus avoided.

This is another instance of incorrect use of list iterator and checking it for NULL. The list iterator value 'map' will *always* be set and non-NULL by list_for_each_entry(), so it is incorrect to assume that the iterator value will be NULL if the list is empty (in this case, the check 'if (!map) {' will always be false and never exit as expected). To fix the bug, use a new variable 'iter' as the list iterator, while use the original variable 'map' as a dedicated pointer to point to the found element.

2022-05-19binder: fix potential UAF of target_{proc,thread}Carlos Llamas
Commit 9474be34a727 ("binder: add failed transaction logging info") dereferences target_{proc,thread} after they have been potentially freed by binder_proc_dec_tmpref() and binder_thread_dec_tmpref(). This patch delays the release of the two references after their last usage. Fixes the following two errors reported by smatch: drivers/android/binder.c:3562 binder_transaction() error: dereferencing freed memory 'target_proc' drivers/android/binder.c:3563 binder_transaction() error: dereferencing freed memory 'target_thread' Fixes: 9474be34a727 ("binder: add failed transaction logging info") Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Todd Kjos <tkjos@google.com> Signed-off-by: Carlos Llamas <cmllamas@google.com> Link: https://lore.kernel.org/r/20220517185817.598872-1-cmllamas@google.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next Chanwoo writes: Update extcon next for v5.19 Detailed description for this pull request: 1. update extcon core driver - extcon_get_extcon_dev() has been almost used to get the extcon device on booting time. If extcon provider driver is probed at late time, the extcon consumer driver get the -EPROBE_DEFER return value. It requires the inefficient handling code of -EPROBE_DEFER. Instead, extcon_get_extcon_dev() will return -EPROBE_DEFER if the required extcon device is none. It makes the extcon consumer driver to be simplified when getting extcon device. - Register device after dev_set_drvdata because of accessing the sysfs attributes at timing of between drv_set_data and device_register. - Fix some kernel-doc comments of extcon functions. 2. update extcon provider driver - Update extcon-intel-int3496.c : Add support for controlling vbus power via regulator and support to the extcon-intel-int3496.c driver to bind to devices without an ACPi companion. And fix the minor clean-up. - Use struct_size() helper on extcon-usbc-cros-ec.c - Remove the disable irq operation in system sleep for using vbus/id gpio as the wakeup source on extcon-usb-gpio.c - Add support of SM5703 device by using existing extcon-sm5502.c and rename i2c_devic_id from sm5703 to sm5703-muic to reduce confusion between SM5703 MFD device and extcon device. - Add usb role class support and add queue work sync before driver release on extcon-ptn5150.c * tag 'extcon-next-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon: extcon: Modify extcon device to be created after driver data is set extcon: sm5502: Clarify SM5703's i2c device ID extcon: ptn5150: Add usb role class support extcon: ptn5150: Add queue work sync before driver release extcon: sm5502: Add support for SM5703 dt-bindings: extcon: bindings for SM5703 extcon: usb-gpio: Remove disable irq operation in system sleep extcon: Fix some kernel-doc comments extcon: usbc-cros-ec: Use struct_size() helper in kzalloc() extcon: int3496: Add support for controlling Vbus through a regulator extcon: int3496: Add support for binding to plain platform devices extcon: int3496: Request non-exclusive access to the ID GPIO extcon: int3496: Make the driver a bit less verbose extcon: Fix extcon_get_extcon_dev() error handling
