2018-12-27um: Include sys/uio.h to have writev()Richard Weinberger1-0/+1
sys/uio.h gives us writev(), otherwise the build might fail on some systems. Fixes: 49da7e64f33e ("High Performance UML Vector Network Driver") Signed-off-by: Richard Weinberger <[email protected]>

Pull networking updates from David Miller: 1) New ipset extensions for matching on destination MAC addresses, from Stefano Brivio. 2) Add ipv4 ttl and tos, plus ipv6 flow label and hop limit offloads to nfp driver. From Stefano Brivio. 3) Implement GRO for plain UDP sockets, from Paolo Abeni. 4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT bit so that we could support the entire vlan_tci value. 5) Rework the IPSEC policy lookups to better optimize more usecases, from Florian Westphal. 6) Infrastructure changes eliminating direct manipulation of SKB lists wherever possible, and to always use the appropriate SKB list helpers. This work is still ongoing... 7) Lots of PHY driver and state machine improvements and simplifications, from Heiner Kallweit. 8) Various TSO deferral refinements, from Eric Dumazet. 9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov. 10) Batch dropping of XDP packets in tuntap, from Jason Wang. 11) Lots of cleanups and improvements to the r8169 driver from Heiner Kallweit, including support for ->xmit_more. This driver has been getting some much needed love since he started working on it. 12) Lots of new forwarding selftests from Petr Machata. 13) Enable VXLAN learning in mlxsw driver, from Ido Schimmel. 14) Packed ring support for virtio, from Tiwei Bie. 15) Add new Aquantia AQtion USB driver, from Dmitry Bezrukov. 16) Add XDP support to dpaa2-eth driver, from Ioana Ciocoi Radulescu. 17) Implement coalescing on TCP backlog queue, from Eric Dumazet. 18) Implement carrier change in tun driver, from Nicolas Dichtel. 19) Support msg_zerocopy in UDP, from Willem de Bruijn. 20) Significantly improve garbage collection of neighbor objects when the table has many PERMANENT entries, from David Ahern. 21) Remove egdev usage from nfp and mlx5, and remove the facility completely from the tree as it no longer has any users. From Oz Shlomo and others. 22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and therefore abort the operation before the commit phase (which is the NETDEV_CHANGEADDR event). From Petr Machata. 23) Add indirect call wrappers to avoid retpoline overhead, and use them in the GRO code paths. From Paolo Abeni. 24) Add support for netlink FDB get operations, from Roopa Prabhu. 25) Support bloom filter in mlxsw driver, from Nir Dotan. 26) Add SKB extension infrastructure. This consolidates the handling of the auxiliary SKB data used by IPSEC and bridge netfilter, and is designed to support the needs to MPTCP which could be integrated in the future. 27) Lots of XDP TX optimizations in mlx5 from Tariq Toukan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1845 commits) net: dccp: fix kernel crash on module load drivers/net: appletalk/cops: remove redundant if statement and mask bnx2x: Fix NULL pointer dereference in bnx2x_del_all_vlans() on some hw net/net_namespace: Check the return value of register_pernet_subsys() net/netlink_compat: Fix a missing check of nla_parse_nested ieee802154: lowpan_header_create check must check daddr net/mlx4_core: drop useless LIST_HEAD mlxsw: spectrum: drop useless LIST_HEAD net/mlx5e: drop useless LIST_HEAD iptunnel: Set tun_flags in the iptunnel_metadata_reply from src net/mlx5e: fix semicolon.cocci warnings staging: octeon: fix build failure with XFRM enabled net: Revert recent Spectre-v1 patches. can: af_can: Fix Spectre v1 vulnerability packet: validate address length if non-zero nfc: af_nfc: Fix Spectre v1 vulnerability phonet: af_phonet: Fix Spectre v1 vulnerability net: core: Fix Spectre v1 vulnerability net: minor cleanup in skb_ext_add() net: drop the unused helper skb_ext_get() ...

To make up for this, we do have a birthday of sorts to celebrate: SELinux turns 18 years old this December. Perhaps not the most exciting thing in the world for most people, but I think it's safe to say that anyone reading this email doesn't exactly fall into the "most people" category. Back to business and the pull request itself: Ondrej has five patches in this pull request and I lump them into three categories: one patch to always allow submounts (using similar logic to elsewhere in the kernel), one to fix some issues with the SELinux policydb, and the others to cleanup and improve the SELinux sidtab. The other patches from Alexey and Petr and trivial fixes that are adequately described in their respective subject lines. With this last pull request of the year, I want to thank everyone who has contributed patches, testing, and reviews to the SELinux project this year, and the past 18 years.

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit Pull audit updates from Paul Moore: "In the finest of holiday of traditions, I have a number of gifts to share today. While most of them are re-gifts from others, unlike the typical re-gift, these are things you will want in and around your tree; I promise. This pull request is perhaps a bit larger than our typical PR, but most of it comes from Jan's rework of audit's fanotify code; a very welcome improvement. We ran this through our normal regression tests, as well as some newly created stress tests and everything looks good. Richard added a few patches, mostly cleaning up a few things and and shortening some of the audit records that we send to userspace; a change the userspace folks are quite happy about. Finally YueHaibing and I kick in a few patches to simplify things a bit and make the code less prone to errors.

2018-12-26f2fs: fix validation of the block count in sanity_check_raw_superMartin Blumenstingl1-3/+3
Treat "block_count" from struct f2fs_super_block as 64-bit little endian value in sanity_check_raw_super() because struct f2fs_super_block declares "block_count" as "__le64". This fixes a bug where the superblock validation fails on big endian devices with the following error: F2FS-fs (sda1): Wrong segment_count / block_count (61439 > 0) F2FS-fs (sda1): Can't find valid F2FS filesystem in 1th superblock F2FS-fs (sda1): Wrong segment_count / block_count (61439 > 0) F2FS-fs (sda1): Can't find valid F2FS filesystem in 2th superblock As result of this the partition cannot be mounted. With this patch applied the superblock validation works fine and the partition can be mounted again: F2FS-fs (sda1): Mounted with checkpoint version = 7c84 My little endian x86-64 hardware was able to mount the partition without this fix. To confirm that mounting f2fs filesystems works on big endian machines again I tested this on a 32-bit MIPS big endian (lantiq) device.

When there is a failure in f2fs_fill_super() after/during the recovery of fsync'd nodes, it frees the current sbi and retries again. This time the mount is successful, but the files that got recovered before retry, still holds the extent tree, whose extent nodes list is corrupted since sbi and sbi->extent_list is freed up.
