sctp: fix strchange_flags name for Stream Change Event

2018-11-23T07:19:26Z

[ Upstream commit fd82d61ba142f0b83463e47064bf5460aac57b6e ] As defined in rfc6525#section-6.1.3, SCTP_STREAM_CHANGE_DENIED and SCTP_STREAM_CHANGE_FAILED should be used instead of SCTP_ASSOC_CHANGE_DENIED and SCTP_ASSOC_CHANGE_FAILED. To keep the compatibility, fix it by adding two macros.

UAPI: ndctl: Fix g++-unsupported initialisation in headers

2018-11-13T19:14:57Z

[ Upstream commit 9607871f37dc3e717639694b8d0dc738f2a68efc ] The following code in the linux/ndctl header file: static inline const char *nvdimm_bus_cmd_name(unsigned cmd) { static const char * const names[] = { [ND_CMD_ARS_CAP] = "ars_cap", [ND_CMD_ARS_START] = "ars_start", [ND_CMD_ARS_STATUS] = "ars_status", [ND_CMD_CLEAR_ERROR] = "clear_error", [ND_CMD_CALL] = "cmd_call", }; if (cmd < ARRAY_SIZE(names) && names[cmd]) return names[cmd]; return "unknown"; } is broken in a number of ways: (1) ARRAY_SIZE() is not generally defined. (2) g++ does not support "non-trivial" array initialisers fully yet. (3) Every file that calls this function will acquire a copy of names[]. The same goes for nvdimm_cmd_name(). Fix all three by converting to a switch statement where each case returns a string. That way if cmd is a constant, the compiler can trivially reduce it and, if not, the compiler can use a shared lookup table if it thinks that is more efficient. A better way would be to remove these functions and their arrays from the header entirely.

ip: discard IPv4 datagrams with overlapping segments.

2018-09-19T20:43:47Z

This behavior is required in IPv6, and there is little need to tolerate overlapping fragments in IPv4. This change simplifies the code and eliminates potential DDoS attack vectors.

ethtool: Remove trailing semicolon for static inline

uapi/linux/keyctl.h: don't use C++ reserved keyword as a struct member name

2018-09-15T07:45:35Z

commit 8a2336e549d385bb0b46880435b411df8d8200e8 upstream. Since this header is in "include/uapi/linux/", apparently people want to use it in userspace programs -- even in C++ ones. However, the header uses a C++ reserved keyword ("private"), so change that to "dh_private" instead to allow the header file to be used in C++ userspace.

KVM: x86: Add a framework for supporting MSR-based features

2018-08-15T16:12:59Z

commit 801e459a6f3a63af9d447e6249088c76ae16efc4 upstream Provide a new KVM capability that allows bits within MSRs to be recognized as features. Two new ioctls are added to the /dev/kvm ioctl routine to retrieve the list of these MSRs and then retrieve their values. A kvm_x86_ops callback is used to determine support for the listed MSR-based features.

ASoC: topology: Add missing clock gating parameter when parsing hw_configs

2018-08-03T05:50:42Z

[ Upstream commit 933e1c4a667103c4d10ebdc9505a0a6abd8c3fbd ] Clock gating parameter is a part of `dai_fmt`. It is supported by `alsa-lib` when creating a topology binary file, but ignored by kernel when loading this topology file. After applying this commit, the clock gating parameter is not ignored any more. This solution is backwards compatible. The existing behaviour is not broken, because by default the parameter value is 0 and is ignored. snd_soc_tplg_hw_config.clock_gated = 0 => no effect snd_soc_tplg_hw_config.clock_gated = 1 => SND_SOC_DAIFMT_GATED snd_soc_tplg_hw_config.clock_gated = 2 => SND_SOC_DAIFMT_CONT For example, the following config, based on alsa-lib/src/conf/topology/broadwell/broadwell.conf, is now supported: ~~~~ SectionHWConfig."CodecHWConfig" { id "1" format "I2S" # physical audio format. pm_gate_clocks "true" # clock can be gated } SectionLink."Codec" { # used for binding to the physical link id "0" hw_configs [ "CodecHWConfig" ] default_hw_conf_id "1" } ~~~~ Signed-off-by: Kirill Marinushkin Reviewed-by: Pierre-Louis Bossart Cc: Jaroslav Kysela Cc: Takashi Iwai Cc: Mark Brown Cc: Pan Xiuli Cc: Liam Girdwood Cc: linux-kernel@vger.kernel.org Cc: alsa-devel@alsa-project.org Signed-off-by: Mark Brown Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman
