2020-12-04mmc: tmio: add hook for custom busy_wait calculationWolfram Sang
Newer SDHI variants can 'wait while busy' longer than the generic TMIO. Provide a hook to get the maximum cycle count to wait for. If the hook is not populated, fall back to a generic version which works well with all older TMIO/SDHI variants.

2020-12-04mmc: tmio: set max_busy_timeoutWolfram Sang
Set max_busy_timeouts for variants known to support the TOPxx bits in the SD_OPTION register. The timeout mechanism was running in the background but not yet properly handled in the driver. So, let the MMC core know when to not use R1B to avoid unhandled timeouts. My datasheets for older variants (tmio_mmc.c) suggest that they support it, too. However, actual bit descriptions are lacking, so I chose an opt-in approach.

2020-12-04fs, close_range: add flag CLOSE_RANGE_CLOEXECGiuseppe Scrivano
When the flag CLOSE_RANGE_CLOEXEC is set, close_range doesn't immediately close the files but it sets the close-on-exec bit. It is useful for e.g. container runtimes that usually install a seccomp profile "as late as possible" before execv'ing the container process itself. The container runtime could either do: 1 2 - install_seccomp_profile(); - close_range(MIN_FD, MAX_INT, 0); - close_range(MIN_FD, MAX_INT, 0); - install_seccomp_profile(); - execve(...); - execve(...); Both alternative have some disadvantages. In the first variant the seccomp_profile cannot block the close_range syscall, as well as opendir/read/close/... for the fallback on older kernels. In the second variant, close_range() can be used only on the fds that are not going to be needed by the runtime anymore, and it must be potentially called multiple times to account for the different ranges that must be closed. Using close_range(..., ..., CLOSE_RANGE_CLOEXEC) solves these issues. The runtime is able to use the existing open fds, the seccomp profile can block close_range() and the syscalls used for its fallback.

2020-12-04pinctrl: amd: remove debounce filter setting in IRQ type settingCoiby Xu
Debounce filter setting should be independent from IRQ type setting because according to the ACPI specs, there are separate arguments for specifying debounce timeout and IRQ type in GpioIo() and GpioInt(). Together with commit 06abe8291bc31839950f7d0362d9979edc88a666 ("pinctrl: amd: fix incorrect way to disable debounce filter") and Andy's patch "gpiolib: acpi: Take into account debounce settings" [1], this will fix broken touchpads for laptops whose BIOS set the debounce timeout to a relatively large value. For example, the BIOS of Lenovo AMD gaming laptops including Legion-5 15ARH05 (R7000), Legion-5P (R7000P) and IdeaPad Gaming 3 15ARH05, set the debounce timeout to 124.8ms. This led to the kernel receiving only ~7 HID reports per second from the Synaptics touchpad (MSFT0001:00 06CB:7F28). Existing touchpads like [2][3] are not troubled by this bug because the debounce timeout has been set to 0 by the BIOS before enabling the debounce filter in setting IRQ type.

2020-12-04batman-adv: Allow selection of routing algorithm over rtnetlinkSven Eckelmann
A batadv net_device is associated to a B.A.T.M.A.N. routing algorithm. This algorithm has to be selected before the interface is initialized and cannot be changed after that. The only way to select this algorithm was a module parameter which specifies the default algorithm used during the creation of the net_device. This module parameter is writeable over /sys/module/batman_adv/parameters/routing_algo and thus allows switching of the routing algorithm: 1. change routing_algo parameter 2. create new batadv net_device But this is not race free because another process can be scheduled between 1 + 2 and in that time frame change the routing_algo parameter again. It is much cleaner to directly provide this information inside the rtnetlink's RTM_NEWLINK message. The two processes would be (in regards of the creation parameter of their batadv interfaces) be isolated. This also eases the integration of batadv devices inside tools like network-manager or systemd-networkd which are not expecting to operate on /sys before a new net_device is created.

2020-12-04batman-adv: Prepare infrastructure for newlink settingsSven Eckelmann
The batadv generic netlink family can be used to retrieve the current state and set various configuration settings. But there are also settings which must be set before the actual interface is created. The rtnetlink already uses IFLA_INFO_DATA to allow net_device families to transfer such configurations. The minimal required functionality for this is now available for the batadv rtnl_link_ops. Also a new IFLA class of attributes will be attached to it because rtnetlink only allows 51 different attributes but batadv_nl_attrs already contains 62 attributes.

2020-12-04crypto: arm/aes-ce - work around Cortex-A57/A72 silion errataArd Biesheuvel
ARM Cortex-A57 and Cortex-A72 cores running in 32-bit mode are affected by silicon errata #1742098 and #1655431, respectively, where the second instruction of a AES instruction pair may execute twice if an interrupt is taken right after the first instruction consumes an input register of which a single 32-bit lane has been updated the last time it was modified. This is not such a rare occurrence as it may seem: in counter mode, only the least significant 32-bit word is incremented in the absence of a carry, which makes our counter mode implementation susceptible to these errata. So let's shuffle the counter assignments around a bit so that the most recent updates when the AES instruction pair executes are 128-bit wide.

2020-12-04crypto: ecdh - avoid unaligned accesses in ecdh_set_secret()Ard Biesheuvel
ecdh_set_secret() casts a void* pointer to a const u64* in order to feed it into ecc_is_key_valid(). This is not generally permitted by the C standard, and leads to actual misalignment faults on ARMv6 cores. In some cases, these are fixed up in software, but this still leads to performance hits that are entirely avoidable. So let's copy the key into the ctx buffer first, which we will do anyway in the common case, and which guarantees correct alignment.

2020-12-03selftests/bpf: Fix invalid use of strncat in test_sockmapAndrii Nakryiko
strncat()'s third argument is how many bytes will be added *in addition* to already existing bytes in destination. Plus extra zero byte will be added after that. So existing use in test_sockmap has many opportunities to overflow the string and cause memory corruptions. And in this case, GCC complains for a good reason. Fixes: 16962b2404ac ("bpf: sockmap, add selftests") Fixes: 73563aa3d977 ("selftests/bpf: test_sockmap, print additional test options") Fixes: 1ade9abadfca ("bpf: test_sockmap, add options for msg_pop_data() helper") Fixes: 463bac5f1ca7 ("bpf, selftests: Add test for ktls with skb bpf ingress policy") Fixes: e9dd904708c4 ("bpf: add tls support for testing in test_sockmap") Fixes: 753fb2ee0934 ("bpf: sockmap, add msg_peek tests to test_sockmap") Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Link: https://lore.kernel.org/bpf/20201203235440.2302137-2-andrii@kernel.org
