2019-02-24Merge branch 'Add-tests-for-unlocked-flower-classifier-implementation'David S. Miller
Vlad Buslov says: ==================== Add tests for unlocked flower classifier implementation Implement tests for tdc testsuite to verify concurrent rules update with rtnl-unlocked flower classifier implementation. The goal of these tests is to verify general flower classifier correctness by updating filters on same classifier instance in parallel and to verify its atomicity by concurrently updating filters in same handle range. All three filter update operations (add, replace, delete) are tested. Existing script tdc_batch.py is re-used for batch file generation. It is extended with several optional CLI arguments that are needed for concurrency tests. Thin wrapper tdc_multibatch.py is implemented on top of tdc_batch.py to simplify its usage when generating multiple batch files for several test configurations. Parallelism in tests is implemented by running multiple instances of tc in batch mode with xargs tool. Xargs is chosen for its ease of use and because it is available by default on most modern Linux distributions. ==================== Acked-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.

Extend tdc_multibatch.py with additional options required to implement the test: common prefix for all generated batch files, first value of filter handle range, MAC address prefix modifier. These are necessary to allow creating batch files with unique keys and handle ranges with multiple invocation of tdc_multibatch.py helper script.

In this case only one tc instance succeeds in deleting a filter with particular handle. To mitigate expected failures of all other instances, run tc with 'force' option to continue processing batch file in case of errors and expect xargs to return code '123' that indicates that invocation of command(s) exited with error in range 1-125.

2019-02-24selftests: tdc_batch.py: add options needed for concurrency testsVlad Buslov

This is needed for testing filter deletion where it is necessary to know exact handles of configured filters. - Add optional argument to specify filter operation type (possible values are ['add', 'del', 'replace']) instead of hardcoded "add" value. This allows generation of batches for filter addition, deletion and replacement. - Add optional argument to allow user to change mac address prefix that is used for all filters in batch.

2019-02-24net: Skip GSO length estimation if transport header is not setMaxim Mikityanskiy
qdisc_pkt_len_init expects transport_header to be set for GSO packets. Patch [1] skips transport_header validation for GSO packets that don't have network_header set at the moment of calling virtio_net_hdr_to_skb, and allows them to pass into the stack. After patch [2] no placeholder value is assigned to transport_header if dissection fails, so this patch adds a check to the place where the value of transport_header is used.

2019-02-24ACPICA: ACPI 6.3: add PCC operation region support for AML interpreterErik Schmauss
ACPICA commit a4849944e80f97970e99843f4975850753584a4e This change adds PCC operation region support in the AML interpreter and a default handler for acpiexec. According to the specification, the PCC operation region performs a transaction when the COMD field is written. This allows ASL to write data to other fields before sending the data. In order to accommodate this protocol, a temorary buffer is added to the regionfield object to accumulate writes. If any offset that spans COMD is written, the temporary buffer is sent to the PCC operation region handler to be processed. This change also renames the PCC keyword to platform_comm_channel.

2019-02-24i2c: Allow recovery of the initial IRQ by an I2C client device.Jim Broadus
A previous change allowed I2C client devices to discover new IRQs upon reprobe by clearing the IRQ in i2c_device_remove. However, if an IRQ was assigned in i2c_new_device, that information is lost. For example, the touchscreen and trackpad devices on a Dell Inspiron laptop are I2C devices whose IRQs are defined by ACPI extended IRQ types. The client device structures are initialized during an ACPI walk. After removing the i2c_hid device, modprobe fails. This change caches the initial IRQ value in i2c_new_device and then resets the client device IRQ to the initial value in i2c_device_remove.
