2019-10-01net: rtnetlink: introduce helper to get net_device instance by ifnameJiri Pirko
Introduce helper function rtnl_get_dev() that gets net_device structure instance pointer according to passed ifname or ifname attribute. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-01net: rtnetlink: unify the code in __rtnl_newlink get dev with the restJiri Pirko
__rtnl_newlink() code flow is a bit different around tb[IFLA_IFNAME] processing comparing to the other places. Change that to be unified with the rest. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2019-10-01net: rtnetlink: add linkprop commands to add and delete alternative ifnamesJiri Pirko
Add two commands to add and delete list of link properties. Implement the first property type along - alternative ifnames. Each net device can have multiple alternative names. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-01net: introduce name_node struct to be used in hashlistJiri Pirko
Introduce name_node structure to hold name of device and put it into hashlist instead of putting there struct net_device directly. Add a necessary infrastructure to manipulate the hashlist. This prepares the code to use the same hashlist for alternative names introduced later in this set. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2019-10-01riscv: Fix memblock reservation for device tree blobAlbert Ou
This fixes an error with how the FDT blob is reserved in memblock. An incorrect physical address calculation exposed the FDT header to unintended corruption, which typically manifested with of_fdt_raw_init() faulting during late boot after fdt_totalsize() returned a wrong value. Systems with smaller physical memory sizes more frequently trigger this issue, as the kernel is more likely to allocate from the DMA32 zone where bbl places the DTB after the kernel image. Commit 671f9a3e2e24 ("RISC-V: Setup initial page tables in two stages") changed the mapping of the DTB to reside in the fixmap area. Consequently, early_init_fdt_reserve_self() cannot be used anymore in setup_bootmem() since it relies on __pa() to derive a physical address, which does not work with dtb_early_va that is no longer a valid kernel logical address. The reserved[0x1] region shows the effect of the pointer underflow resulting from the __pa(initial_boot_params) offset subtraction: [ 0.000000] MEMBLOCK configuration: [ 0.000000] memory size = 0x000000001fe00000 reserved size = 0x0000000000a2e514 [ 0.000000] memory.cnt = 0x1 [ 0.000000] memory[0x0] [0x0000000080200000-0x000000009fffffff], 0x000000001fe00000 bytes flags: 0x0 [ 0.000000] reserved.cnt = 0x2 [ 0.000000] reserved[0x0] [0x0000000080200000-0x0000000080c2dfeb], 0x0000000000a2dfec bytes flags: 0x0 [ 0.000000] reserved[0x1] [0xfffffff080100000-0xfffffff080100527], 0x0000000000000528 bytes flags: 0x0 With the fix applied: [ 0.000000] MEMBLOCK configuration: [ 0.000000] memory size = 0x000000001fe00000 reserved size = 0x0000000000a2e514 [ 0.000000] memory.cnt = 0x1 [ 0.000000] memory[0x0] [0x0000000080200000-0x000000009fffffff], 0x000000001fe00000 bytes flags: 0x0 [ 0.000000] reserved.cnt = 0x2 [ 0.000000] reserved[0x0] [0x0000000080200000-0x0000000080c2dfeb], 0x0000000000a2dfec bytes flags: 0x0 [ 0.000000] reserved[0x1] [0x0000000080e00000-0x0000000080e00527], 0x0000000000000528 bytes flags: 0x0 Fixes: 671f9a3e2e24 ("RISC-V: Setup initial page tables in two stages") Signed-off-by: Albert Ou <aou@eecs.berkeley.edu> Tested-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Anup Patel <anup@brainfault.org> Signed-off-by: Paul Walmsley <paul.walmsley@sifive.com>

2019-10-01selftests/kselftest/runner.sh: Add 45 second timeout per testKees Cook
Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per test") solves the problem of kselftest_harness.h-using binary tests possibly hanging forever. However, scripts and other binaries can still hang forever. This adds a global timeout to each test script run. To make this configurable (e.g. as needed in the "rtc" test case), include a new per-test-directory "settings" file (similar to "config") that can contain kselftest-specific settings. The first recognized field is "timeout". Additionally, this splits the reporting for timeouts into a specific "TIMEOUT" not-ok (and adds exit code reporting in the remaining case).

2019-10-01ASoC: SOF: Intel: hda: Disable DMI L1 entry during captureRanjani Sridharan
There is a known issue on some Intel platforms which causes pause/release to run into xrun's during capture usecases. The suggested workaround to address the issue is to disable the entry of lower power L1 state in the physical DMI link when there is a capture stream open.

2019-10-01ASoC: SOF: Intel: hda: fix warnings during FW loadKai Vehmanen
The "snd_pcm_substream" handle was not initialized properly in hda-loader.c for firmware load. When the HDA DMAs were used to load the firmware, the interrupts related to firmware load also triggered calls to snd_sof_pcm_period_elapsed() on a non-existent ALSA PCM stream. This caused runtime kernel warnings from pcm_lib.c:snd_pcm_period_elapsed().

2019-10-01ASoC: SOF: pcm: harden PCM STOP sequencePan Xiuli
The old STOP sequence is: 1. stop DMA 2. send STOP ipc If delay happen before the steps 1 and 2, the DMA buffer will be empty in short time and cause pipeline xrun then stop the pipeline. Then the step 2 ipc stop will return error as pipeline is already stopped. Suggested change to avoid the issue is to switch the order of steps 1 and 2 for the stop sequence.

Commit b6b6cc9acd7b, changed the call to dwxgmac2_rss_write_reg() passing it the variable cfg->key[i]. As key is an u8 but we write 32 bits at a time we need to cast it into an u32 so that the correct key values are written. Notice that the for loop already takes this into account so we don't try to write past the keys size.
