Pull networking fixes from David Miller: 1) Fix MAC address setting in mac80211 pmsr code, from Johannes Berg. 2) Probe SFP modules after being attached, from Russell King. 3) Byte ordering bug in SMC rx_curs_confirmed code, from Ursula Braun. 4) Revert some r8169 changes that are causing regressions, from Heiner Kallweit. 5) Fix spurious connection timeouts in netfilter nat code, from Florian Westphal. 6) SKB leak in tipc, from Hoang Le. 7) Short packet checkum issue in mlx4, similar to a previous mlx5 change, from Saeed Mahameed. The issue is that whilst padding bytes are usually zero, it is not guarateed and the hardware doesn't take the padding bytes into consideration when generating the checksum. 8) Fix various races in cls_tcindex, from Cong Wang. 9) Need to set stream ext to NULL before freeing in SCTP code, from Xin Long. 10) Fix locking in phy_is_started, from Heiner Kallweit. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (54 commits) net: ethernet: freescale: set FEC ethtool regs version net: hns: Fix object reference leaks in hns_dsaf_roce_reset() mm: page_alloc: fix ref bias in page_frag_alloc() for 1-byte allocs net: phy: fix potential race in the phylib state machine net: phy: don't use locking in phy_is_started selftests: fix timestamping Makefile net: dsa: bcm_sf2: potential array overflow in bcm_sf2_sw_suspend() net: fix possible overflow in __sk_mem_raise_allocated() dsa: mv88e6xxx: Ensure all pending interrupts are handled prior to exit net: phy: fix interrupt handling in non-started states sctp: set stream ext to NULL after freeing it in sctp_stream_outq_migrate sctp: call gso_reset_checksum when computing checksum in sctp_gso_segment net/mlx5e: XDP, fix redirect resources availability check net/mlx5: Fix a compilation warning in events.c net/mlx5: No command allowed when command interface is not ready net/mlx5e: Fix NULL pointer derefernce in set channels error flow netfilter: nft_compat: use-after-free when deleting targets team: avoid complex list operations in team_nl_cmd_options_set() net_sched: fix two more memory leaks in cls_tcindex net_sched: fix a memory leak in cls_tcindex ...

Commit 36c0f7f0f899 ("arch: unexport asm/shmparam.h for all architectures") is different from the patch I submitted. My patch is this: https://lore.kernel.org/lkml/1546904307-11124-1-git-send-email-yamada.masahiro@socionext.com/T/#u The file renaming part: rename include/{uapi => }/asm-generic/shmparam.h (100%) was lost when it was picked up.

2019-02-12inet_diag: fix reporting cgroup classid and fallback to priorityKonstantin Khlebnikov
Field idiag_ext in struct inet_diag_req_v2 used as bitmap of requested extensions has only 8 bits. Thus extensions starting from DCTCPINFO cannot be requested directly. Some of them included into response unconditionally or hook into some of lower 8 bits. Extension INET_DIAG_CLASS_ID has not way to request from the beginning. This patch bundle it with INET_DIAG_TCLASS (ipv6 tos), fixes space reservation, and documents behavior for other extensions. Also this patch adds fallback to reporting socket priority. This filed is more widely used for traffic classification because ipv4 sockets automatically maps TOS to priority and default qdisc pfifo_fast knows about that. But priority could be changed via setsockopt SO_PRIORITY so INET_DIAG_TOS isn't enough for predicting class. Also cgroup2 obsoletes net_cls classid (it always zero), but we cannot reuse this field for reporting cgroup2 id because it is 64-bit (ino+gen). So, after this patch INET_DIAG_CLASS_ID will report socket priority for most common setup when net_cls isn't set and/or cgroup2 in use.

2019-01-24virtio: support VIRTIO_F_ORDER_PLATFORMTiwei Bie
This patch introduces the support for VIRTIO_F_ORDER_PLATFORM. If this feature is negotiated, the driver must use the barriers suitable for hardware devices. Otherwise, the device and driver are assumed to be implemented in software, that is they can be assumed to run on identical CPUs in an SMP configuration. Thus a weaker form of memory barriers is sufficient to yield better performance. It is recommended that an add-in card based PCI device offers this feature for portability. The device will fail to operate further or will operate in a slower emulation mode if this feature is offered but not accepted.

The usec part of the timeval is defined as __kernel_suseconds_t tv_usec; /* microseconds */ Arnd noticed that sparc64 is the only architecture that defines __kernel_suseconds_t as int rather than long. This breaks the current y2038 fix for kernel as we only access and define the timeval struct for non-kernel use cases. But, this was hidden by an another typo in the use of __KERNEL__ qualifier.

2019-01-06fscrypt: add Adiantum supportEric Biggers
Add support for the Adiantum encryption mode to fscrypt. Adiantum is a tweakable, length-preserving encryption mode with security provably reducible to that of XChaCha12 and AES-256, subject to a security bound. It's also a true wide-block mode, unlike XTS. See the paper "Adiantum: length-preserving encryption for entry-level processors" (https://eprint.iacr.org/2018/720.pdf) for more details. Also see commit 059c2a4d8e16 ("crypto: adiantum - add Adiantum support"). On sufficiently long messages, Adiantum's bottlenecks are XChaCha12 and the NH hash function. These algorithms are fast even on processors without dedicated crypto instructions. Adiantum makes it feasible to enable storage encryption on low-end mobile devices that lack AES instructions; currently such devices are unencrypted. On ARM Cortex-A7, on 4096-byte messages Adiantum encryption is about 4 times faster than AES-256-XTS encryption; decryption is about 5 times faster. In fscrypt, Adiantum is suitable for encrypting both file contents and names. With filenames, it fixes a known weakness: when two filenames in a directory share a common prefix of >= 16 bytes, with CTS-CBC their encrypted filenames share a common prefix too, leaking information. Adiantum does not have this problem. Since Adiantum also accepts long tweaks (IVs), it's also safe to use the master key directly for Adiantum encryption rather than deriving per-file keys, provided that the per-file nonce is included in the IVs and the master key isn't used for any other encryption mode. This configuration saves memory and improves performance. A new fscrypt policy flag is added to allow users to opt-in to this configuration.

2019-01-04fat: move MAX_FAT to fat.h and change it to inline functionCarmeli Tamir
MAX_FAT is useless in msdos_fs.h, since it uses the MSDOS_SB function that is defined in fat.h. So really, this macro can be only called from code that already includes fat.h. Hence, this patch moves it to fat.h, right after MSDOS_SB is defined. I also changed it to an inline function in order to save the double call to MSDOS_SB. This was suggested by joe@perches.com in the previous version. This patch is required for the next in the series, in which the variant (whether this is FAT12, FAT16 or FAT32) checks are replaced with new macros.

2019-01-04fat: remove FAT_FIRST_ENT macroCarmeli Tamir
The comment edited in this patch was the only reference to the FAT_FIRST_ENT macro, which is not used anymore. Moreover, the commented line of code does not compile with the current code. Since the FAT_FIRST_ENT macro checks the FAT variant in a way that the patch series changes, I removed it, and instead wrote a clear explanation of what was checked. I verified that the changed comment is correct according to Microsoft FAT spec, search for "BPB_Media" in the following references: 1.

2019-01-04include/uapi/linux/msdos_fs.h: use MSDOS_NAME for volume label sizeCarmeli Tamir
The FAT file system volume label file stored in the root directory should match the volume label field in the FAT boot sector. As consequence, the max length of these fields ought to be the same. This patch replaces the magic '11' usef in the struct fat_boot_sector with MSDOS_NAME, which is used in struct msdos_dir_entry. Please check the following references: 1.

Microsoft Extensible Firmware Initiative, FAT32 File System Specification (https://staff.washington.edu/dittrich/misc/fatgen103.pdf). Search for 'volume label'. 3. User space code that creates FAT filesystem sometimes uses MSDOS_NAME for the label, sometimes not. Search for 'if (memcmp(label, NO_NAME, MSDOS_NAME))'.

2019-01-04autofs: add strictexpire mount optionIan Kent
Commit 092a53452bb7 ("autofs: take more care to not update last_used on path walk") helped to (partially) resolve a problem where automounts were not expiring due to aggressive accesses from user space. This patch was later reverted because, for very large environments, it meant more mount requests from clients and when there are a lot of clients this caused a fairly significant increase in server load. But there is a need for both types of expire check, depending on use case, so add a mount option to allow for strict update of last use of autofs dentrys (which just means not updating the last use on path walk access).
