2019-09-04tty: n_gsm: add ioctl to map serial device to mux'ed ttyMartin Hundebøll
Guessing the first tty for a gsm0710 multiplexed serial device is not currently possible, which makes it racy to use with multiple modems. Add a way to map the physical serial tty to its related mux devices using an ioctl.

2019-09-04tty: serial: Add linflexuart driver for S32V234Stefan-gabriel Mirea
Introduce support for LINFlex driver, based on: - the version of Freescale LPUART driver after commit b3e3bf2ef2c7 ("Merge 4.0-rc7 into tty-next"); - commit abf1e0a98083 ("tty: serial: fsl_lpuart: lock port on console write"). In this basic version, the driver can be tested using initramfs and relies on the clocks and pin muxing set up by U-Boot. Remarks concerning the earlycon support: - LinFlexD does not allow character transmissions in the INIT mode (see section 47.4.2.1 in the reference manual[1]). Therefore, a mutual exclusion between the first linflex_setup_watermark/linflex_set_termios executions and linflex_earlycon_putchar was employed and the characters normally sent to earlycon during initialization are kept in a buffer and sent afterwards. - Empirically, character transmission is also forbidden within the last 1-2 ms before entering the INIT mode, so we use an explicit timeout (PREINIT_DELAY) between linflex_earlycon_putchar and the first call to linflex_setup_watermark. - U-Boot currently uses the UART FIFO mode, while this driver makes the transition to the buffer mode. Therefore, the earlycon putchar function matches the U-Boot behavior before initializations and the Linux behavior after.

2019-08-31xsk: add support to allow unaligned chunk placementKevin Laatz
Currently, addresses are chunk size aligned. This means, we are very restricted in terms of where we can place chunk within the umem. For example, if we have a chunk size of 2k, then our chunks can only be placed at 0,2k,4k,6k,8k... and so on (ie. every 2k starting from 0). This patch introduces the ability to use unaligned chunks. With these changes, we are no longer bound to having to place chunks at a 2k (or whatever your chunk size is) interval. Since we are no longer dealing with aligned chunks, they can now cross page boundaries. Checks for page contiguity have been added in order to keep track of which pages are followed by a physically contiguous page.

2019-08-28perf: Allow normal events to output AUX dataAlexander Shishkin
In some cases, ordinary (non-AUX) events can generate data for AUX events. For example, PEBS events can come out as records in the Intel PT stream instead of their usual DS records, if configured to do so. One requirement for such events is to consistently schedule together, to ensure that the data from the "AUX output" events isn't lost while their corresponding AUX event is not scheduled. We use grouping to provide this guarantee: an "AUX output" event can be added to a group where an AUX event is a group leader, and provided that the former supports writing to the latter.

2019-08-24erofs: move erofs out of stagingGao Xiang
EROFS filesystem has been merged into linux-staging for a year. EROFS is designed to be a better solution of saving extra storage space with guaranteed end-to-end performance for read-only files with the help of reduced metadata, fixed-sized output compression and decompression inplace technologies. In the past year, EROFS was greatly improved by many people as a staging driver, self-tested, betaed by a large number of our internal users, successfully applied to almost all in-service HUAWEI smartphones as the part of EMUI 9.1 and proven to be stable enough to be moved out of staging. EROFS is a self-contained filesystem driver. Although there are still some TODOs to be more generic, we have a dedicated team actively keeping on working on EROFS in order to make it better with the evolution of Linux kernel as the other in-kernel filesystems. As Pavel suggested, it's better to do as one commit since git can do moves and all histories will be saved in this way. Let's promote it from staging and enhance it more actively as a "real" part of kernel for more wider scenarios!

802.11ay specification defines Enhanced Directional Multi-Gigabit (EDMG) STA and AP which allow channel bonding of 2 channels and more. Introduce new NL attributes that are needed for enabling and configuring EDMG support. Two new attributes are used by kernel to publish driver's EDMG capabilities to the userspace: NL80211_BAND_ATTR_EDMG_CHANNELS - bitmap field that indicates the 2.16 GHz channel(s) that are supported by the driver. When this attribute is not set it means driver does not support EDMG. NL80211_BAND_ATTR_EDMG_BW_CONFIG - represent the channel bandwidth configurations supported by the driver. Additional two new attributes are used by the userspace for connect command and for AP configuration: NL80211_ATTR_WIPHY_EDMG_CHANNELS NL80211_ATTR_WIPHY_EDMG_BW_CONFIG New rate info flag - RATE_INFO_FLAGS_EDMG, can be reported from driver and used for bitrate calculation that will take into account EDMG according to the 802.11ay specification.

Add a new command for the bpf() system call: BPF_BTF_GET_NEXT_ID is used to cycle through all BTF objects loaded on the system. The motivation is to be able to inspect (list) all BTF objects presents on the system.

2019-08-19sctp: add SCTP_AUTH_SUPPORTED sockoptXin Long
SCTP_AUTH_SUPPORTED sockopt is used to set enpoint's auth flag. With this feature, each endpoint will have its own flag for its future asoc's auth_capable, instead of netns auth flag. Note that when both ep's auth_enable is enabled, endpoint auth related data should be initialized. If asconf_enable is also set, SCTP_CID_ASCONF/SCTP_CID_ASCONF_ACK should be added into auth_chunk_list. Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S.

2019-08-19media: videodev2.h: add V4L2_FMT_FLAG_DYN_RESOLUTIONMaxime Jourdan
Add an enum_fmt format flag to specifically tag coded formats where dynamic resolution switching is supported by the device. This is useful for some codec drivers that can support dynamic resolution switching for one or more of their listed coded formats. It allows userspace to know whether it should extract the video parameters itself, or if it can rely on the device to send V4L2_EVENT_SOURCE_CHANGE when such changes are detected.

Add an enum_fmt format flag to specifically tag coded formats where full bytestream parsing is supported by the device. Some stateful decoders are capable of fully parsing a bytestream, but others require that userspace pre-parses the bytestream into frames or fields (see the corresponding pixelformat descriptions for details). If this flag is set, then this pre-parsing step is not required (but still possible, of course).

2019-08-19netfilter: xt_nfacct: Fix alignment mismatch in xt_nfacct_match_infoJuliana Rodrigueiro
When running a 64-bit kernel with a 32-bit iptables binary, the size of the xt_nfacct_match_info struct diverges. kernel: sizeof(struct xt_nfacct_match_info) : 40 iptables: sizeof(struct xt_nfacct_match_info)) : 36 Trying to append nfacct related rules results in an unhelpful message. Although it is suggested to look for more information in dmesg, nothing can be found there. # iptables -A <chain> -m nfacct --nfacct-name <acct-object> iptables: Invalid argument. Run `dmesg' for more information. This patch fixes the memory misalignment by enforcing 8-byte alignment within the struct's first revision. This solution is often used in many other uapi netfilter headers.
