2019-06-05xen/swiotlb: don't initialize swiotlb twice on arm64Stefano Stabellini1-1/+11
On arm64 swiotlb is often (not always) already initialized by mem_init. We don't want to initialize it twice, which would trigger a second memory allocation. Moreover, the second memory pool is typically made of high pages and ends up replacing the original memory pool of low pages. As a side effect of this change, it is possible to have low pages in swiotlb-xen on arm64.

2019-06-05s390/mm: fix address space detection in exception handlingGerald Schaefer1-1/+4
Commit 0aaba41b58bc ("s390: remove all code using the access register mode") removed access register mode from the kernel, and also from the address space detection logic. However, user space could still switch to access register mode (trans_exc_code == 1), and exceptions in that mode would not be correctly assigned. Fix this by adding a check for trans_exc_code == 1 to get_fault_type(), and remove the wrong comment line before that function.

The c52f nano receiver is a mouse only receiver. This means that it needs some special handling compared to the c534 nano receiver: 1) It sends unnumbered mouse reports with a size of 8 bytes, so we need to extend the unnumbered mouse report handling to support reports upto 8 bytes large 2) It mouse reports have the same high-resolution format as those from the gaming mouse receivers 3) It can report consumer/multimedia buttons on its second interface, since this is a mouse-only receiver these must be forwarded to the mouse child device and not to the keyboard child-device (which will not exist) Link: https://bugzilla.kernel.org/show_bug.cgi?id=203619 Signed-off-by: Hans de Goede <[email protected]> Acked-by: Jiri Kosina <[email protected]> Signed-off-by: Benjamin Tissoires <[email protected]>

2019-06-05arm64: cpufeature: Fix missing ZFR0 in __read_sysreg_by_encoding()Dave Martin1-0/+1
In commit 06a916feca2b ("arm64: Expose SVE2 features for userspace"), new hwcaps are added that are detected via fields in the SVE-specific ID register ID_AA64ZFR0_EL1. In order to check compatibility of secondary cpus with the hwcaps established at boot, the cpufeatures code uses __read_sysreg_by_encoding() to read this ID register based on the sys_reg field of the arm64_elf_hwcaps[] table. This leads to a kernel splat if an hwcap uses an ID register that __read_sysreg_by_encoding() doesn't explicitly handle, as now happens when exercising cpu hotplug on an SVE2-capable platform. So fix it by adding the required case in there.

2019-06-04udp: only choose unbound UDP socket for multicast when not in a VRFTim Beale1-2/+1
By default, packets received in another VRF should not be passed to an unbound socket in the default VRF. This patch updates the IPv4 UDP multicast logic to match the unicast VRF logic (in compute_score()), as well as the IPv6 mcast logic (in __udp_v6_is_mcast_sock()). The particular case I noticed was DHCP discover packets going to the 255.255.255.255 address, which are handled by __udp4_lib_mcast_deliver(). The previous code meant that running multiple different DHCP server or relay agent instances across VRFs did not work correctly - any server/relay agent in the default VRF received DHCP discover packets for all other VRFs.

Commit 38030d7cb779 ("net/tls: avoid NULL-deref on resync during device removal") tried to fix a potential NULL-dereference by taking the context rwsem. Unfortunately the RX resync may get called from soft IRQ, so we can't use the rwsem to protect from the device disappearing. Because we are guaranteed there can be only one resync at a time (it's called from strparser) use a bit to indicate resync is busy and make device removal wait for the bit to get cleared.

2019-06-04net: dsa: sja1105: Fix link speed not working at 100 Mbps and belowVladimir Oltean1-16/+16
The hardware values for link speed are held in the sja1105_speed_t enum. However they do not increase in the order that sja1105_get_speed_cfg was iterating over them (basically from SJA1105_SPEED_AUTO - 0 - to SJA1105_SPEED_1000MBPS - 1 - skipping the other two). Another bug is that the code in sja1105_adjust_port_config relies on the fact that an invalid link speed is detected by sja1105_get_speed_cfg and returned as -EINVAL. However storing this into an enum that only has positive members will cast it into an unsigned value, and it will miss the negative check. So take the simplest approach and remove the sja1105_get_speed_cfg function and replace it with a simple switch-case statement.

2019-06-05scripts/checkstack.pl: Fix arm64 wrong or unknown architectureGeorge G. Davis1-1/+1
The following error occurs for the `make ARCH=arm64 checkstack` case: aarch64-linux-gnu-objdump -d vmlinux $(find . -name '*.ko') | \ perl ./scripts/checkstack.pl arm64 wrong or unknown architecture "arm64" As suggested by Masahiro Yamada, fix the above error using regular expressions in the same way it was fixed for the `ARCH=x86` case via commit fda9f9903be6 ("scripts/checkstack.pl: automatically handle 32-bit and 64-bit mode for ARCH=x86").

2019-06-05kbuild: tar-pkg: enable communication with jobserverTrevor Bourget1-1/+1
The buildtar script might want to invoke a make, so tell the parent make to pass the jobserver token pipe to the subcommand by prefixing the command with a +. This addresses the issue seen here: /bin/sh ../scripts/package/buildtar tar-pkg make[3]: warning: jobserver unavailable: using -j1. Add '+' to parent make rule. See https://www.gnu.org/software/make/manual/html_node/Job-Slots.html for more information. Signed-off-by: Trevor Bourget <[email protected]> Signed-off-by: Masahiro Yamada <[email protected]>
2019-06-05kconfig: tests: fix recursive inclusion unit testMasahiro Yamada1-3/+3
Adding SPDX license identifier is pretty safe; however, here is one exception. Since commit ec8f24b7faaf ("treewide: Add SPDX license identifier - Makefile/Kconfig"), "make testconfig" would not pass. When Kconfig detects a circular file inclusion, it displays error messages with a file name and a line number prefixed to each line. The unit test checks if Kconfig emits the error messages correctly (this also checks the line number correctness). Now that the test input has the SPDX license identifier at the very top, the line numbers in the expected stderr should be incremented by 1.

2019-06-05kbuild: teach kselftest-merge to find nested config filesDan Rue1-3/+2
Current implementation of kselftest-merge only finds config files that are one level deep using `$(srctree)/tools/testing/selftests/*/config`. Often, config files are added in nested directories, and do not get picked up by kselftest-merge. Use `find` to catch all config files under `$(srctree)/tools/testing/selftests` instead.

2019-06-04nvmet: fix data_len to 0 for bdev-backed write_zeroesMinwoo Im1-0/+1
The WRITE ZEROES command has no data transfer so that we need to initialize the struct (nvmet_req *req)->data_len to 0x0. While (nvmet_req *req)->transfer_len is initialized in nvmet_req_init(), data_len will be initialized by nowhere which might cause the failure with status code NVME_SC_SGL_INVALID_DATA | NVME_SC_DNR randomly. It's because nvmet_req_execute() checks like: if (unlikely(req->data_len != req->transfer_len)) { req->error_loc = offsetof(struct nvme_common_command, dptr); nvmet_req_complete(req, NVME_SC_SGL_INVALID_DATA | NVME_SC_DNR); } else req->execute(req); This patch fixes req->data_len not to be a randomly assigned by initializing it to 0x0 when preparing the command in nvmet_bdev_parse_io_cmd(). nvmet_file_parse_io_cmd() which is for file-backed I/O has already initialized the data_len field to 0x0, though.

2019-06-04ASoC: sun4i-i2s: Add offset to RX channel selectMarcus Cooper1-0/+4
Whilst testing the capture functionality of the i2s on the newer SoCs it was noticed that the recording was somewhat distorted. This was due to the offset not being set correctly on the receiver side.
