2020-05-29take the dummy csum_and_copy_from_user() into net/checksum.hAl Viro
now that can be done conveniently - all non-trivial cases have _HAVE_ARCH_COPY_AND_CSUM_FROM_USER defined, so the fallback in net/checksum.h is used only for dummy (copy_from_user, then csum_partial) implementation. Allowing us to get rid of all dummy instances, both of csum_and_copy_from_user() and csum_partial_copy_from_user(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2020-05-29arm: switch to csum_and_copy_from_user()Al Viro
Note that csum_partial_copy_from_user() is in assembler here, so I'm leaving it alone and just providing the wrapper for it. When/if we go for switching arm to user_access_{begin,end}() (doing domain switches in those), somebody well need to look into that one. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2020-05-29x86_64: csum_..._copy_..._user(): switch to unsafe_..._user()Al Viro
We already have stac/clac pair around the calls of csum_partial_copy_generic(). Stretch that area back, so that it covers the preceding loop (and convert the loop body from __{get,put}_user() to unsafe_{get,put}_user()). That brings the beginning of the areas to the earlier access_ok(), which allows to convert them into user_access_{begin,end}() ones. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2020-05-29Merge branch 'remove-kernel_setsockopt-v4'David S. Miller
Christoph Hellwig says: ==================== remove kernel_setsockopt v4 now that only the dlm calls to sctp are left for kernel_setsockopt, while we haven't really made much progress with the sctp setsockopt refactoring, how about this small series that splits out a sctp_setsockopt_bindx_kernel that takes a kernel space address array to share more code as requested by Marcelo. This should fit in with whatever variant of the refator of sctp setsockopt we go with, but just solved the immediate problem for now. Changes since v3: - dropped all the merged patches, just sctp setsockopt left now - factor out a new sctp_setsockopt_bindx_kernel helper instead of duplicating a small amount of logic Changes since v2: - drop the separately merged kernel_getopt_removal - drop the sctp patches, as there is conflicting cleanup going on - add an additional ACK for the rxrpc changes Changes since v1: - use ->getname for sctp sockets in dlm - add a new ->bind_add struct proto method for dlm/sctp - switch the ipv6 and remaining sctp helpers to inline function so that the ipv6 and sctp modules are not pulled in by any module that could potentially use ipv6 or sctp connections - remove arguments to various sock_* helpers that are always used with the same constant arguments ==================== Signed-off-by: David S.

PHYs using the vsc8574_probe fail to be initialized and their config_init return -EIO leading to errors like: "could not attach PHY: -5". This is because when the conversion of the MSCC PHY driver to use the shared PHY package helpers was done, the base address retrieval and the base PHY read and write helpers in the driver were modified. In particular, the base address retrieval logic was moved from the config_init to the probe. But the vsc8574_probe was forgotten. This patch fixes it.

Modern device tree bindings are supposed to be created as YAML-files in accordance with dt-schema. This commit replaces two DW SPI legacy bare text bindings with YAML file. As before the bindings file states that the corresponding dts node is supposed to be compatible either with generic DW APB SSI controller or with Microsemi/Amazon/Renesas/Intel vendors-specific controllers, to have registers, interrupts and clocks properties. Though in case of Microsemi version of the controller there must be two registers resources specified. Properties like clock-names, reg-io-width, cs-gpio, num-cs, DMA and slave device sub-nodes are optional.

2020-05-29mwifiex: Add support for NL80211_ATTR_MAX_AP_ASSOC_STAPali Rohár
SD8997 firmware sends TLV_TYPE_MAX_CONN with struct hw_spec_max_conn to inform kernel about maximum number of p2p connections and stations in AP mode. During initialization of SD8997 wifi chip kernel prints warning: mwifiex_sdio mmc0:0001:1: Unknown GET_HW_SPEC TLV type: 0x217 This patch adds support for parsing TLV_TYPE_MAX_CONN (0x217) and sets appropriate cfg80211 member 'max_ap_assoc_sta' from retrieved structure. It allows userspace to retrieve NL80211_ATTR_MAX_AP_ASSOC_STA attribute.

2020-05-29airo: Fix read overflows sending packetsDan Carpenter
The problem is that we always copy a minimum of ETH_ZLEN (60) bytes from skb->data even when skb->len is less than ETH_ZLEN so it leads to a read overflow. The fix is to pad skb->data to at least ETH_ZLEN bytes.
