Martin KaFai Lau says: ==================== ipv6: Fixes for pmtu update and DST_NOCACHE route This patchset fixes: 1. An oops during IPv6 pmtu update on a IPv4 GRE running in an IPSec setup 2. Misc fixes on DST_NOCACHE route ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

All DST_NOCACHE rt6_info used to have rt->dst.from set to its parent. After commit 8e3d5be7 ("ipv6: Avoid double dst_free"), DST_NOCACHE is also set to rt6_info which does not have a parent (i.e. rt->dst.from is NULL). This patch catches the rt->dst.from == NULL case.

Since the expires of the DST_NOCACHE rt can be set during the ip6_rt_update_pmtu(), we also need to consider the expires value when doing ip6_dst_check(). This patches creates __rt6_check_expired() to only check the expire value (if one exists) of the current rt. In rt6_dst_from_check(), it adds __rt6_check_expired() as one of the condition check.

The original bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1272571 The setup has a IPv4 GRE tunnel running in a IPSec. The bug happens when ndisc starts sending router solicitation at the gre interface. The simplified oops stack is like: __lock_acquire+0x1b2/0x1c30 lock_acquire+0xb9/0x140 _raw_write_lock_bh+0x3f/0x50 __ip6_ins_rt+0x2e/0x60 ip6_ins_rt+0x49/0x50 ~~~~~~~~ __ip6_rt_update_pmtu.part.54+0x145/0x250 ip6_rt_update_pmtu+0x2e/0x40 ~~~~~~~~ ip_tunnel_xmit+0x1f1/0xf40 __gre_xmit+0x7a/0x90 ipgre_xmit+0x15a/0x220 dev_hard_start_xmit+0x2bd/0x480 __dev_queue_xmit+0x696/0x730 dev_queue_xmit+0x10/0x20 neigh_direct_output+0x11/0x20 ip6_finish_output2+0x21f/0x770 ip6_finish_output+0xa7/0x1d0 ip6_output+0x56/0x190 ~~~~~~~~ ndisc_send_skb+0x1d9/0x400 ndisc_send_rs+0x88/0xc0 ~~~~~~~~ The rt passed to ip6_rt_update_pmtu() is created by icmp6_dst_alloc() and it is not managed by the fib6 tree, so its rt6i_table == NULL. When __ip6_rt_update_pmtu() creates a RTF_CACHE clone, the newly created clone also has rt6i_table == NULL and it causes the ip6_ins_rt() oops. During pmtu update, we only want to create a RTF_CACHE clone from a rt which is currently managed (or owned) by the fib6 tree. It means either rt->rt6i_node != NULL or rt is a RTF_PCPU clone. It is worth to note that rt6i_table may not be NULL even it is not (yet) managed by the fib6 tree (e.g. addrconf_dst_alloc()). Hence, rt6i_node is a better check instead of rt6i_table.

During splicing an af-unix socket to a pipe we have to drop all af-unix socket locks. While doing so we allow another reader to enter unix_stream_read_generic which can read, copy and finally free another skb. If exactly this skb is just in process of being spliced we get a use-after-free report by kasan. First, we must make sure to not have a free while the skb is used during the splice operation. We simply increment its use counter before unlocking the reader lock. Stream sockets have the nice characteristic that we don't care about zero length writes and they never reach the peer socket's queue. That said, we can take the UNIXCB.consumed field as the indicator if the skb was already freed from the socket's receive queue. If the skb was fully consumed after we locked the reader side again we know it has been dropped by a second reader. We indicate a short read to user space and abort the current splice operation. This bug has been found with syzkaller (http://github.com/google/syzkaller) by Dmitry Vyukov.

Building dwmac-ipq806x on a 64-bit architecture produces a harmless warning from gcc: stmmac/dwmac-ipq806x.c: In function 'ipq806x_gmac_probe': include/linux/bitops.h:6:19: warning: overflow in implicit constant conversion [-Woverflow] val = QSGMII_PHY_CDR_EN | stmmac/dwmac-ipq806x.c:333:8: note: in expansion of macro 'QSGMII_PHY_CDR_EN' #define QSGMII_PHY_CDR_EN BIT(0) #define BIT(nr) (1UL << (nr)) This is a result of the type conversion rules in C, when we take the logical OR of multiple different types. In particular, we have and unsigned long QSGMII_PHY_CDR_EN == BIT(0) == (1ul << 0) == 0x0000000000000001ul and a signed int 0xC << QSGMII_PHY_TX_DRV_AMP_OFFSET == 0xc0000000 which together gives a signed long value 0xffffffffc0000001l and when this is passed into a function that takes an unsigned int type, gcc warns about the signed overflow and the loss of the upper 32-bits that are all ones. This patch adds 'ul' type modifiers to the literal numbers passed in here, so now the expression remains an 'unsigned long' with the upper bits all zero, and that avoids the signed overflow and the warning.

Pablo Neira Ayuso: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for your net tree. This large batch that includes fixes for ipset, netfilter ingress, nf_tables dynamic set instantiation and a longstanding Kconfig dependency problem. More specifically, they are: 1) Add missing check for empty hook list at the ingress hook, from Florian Westphal. 2) Input and output interface are swapped at the ingress hook, reported by Patrick McHardy. 3) Resolve ipset extension alignment issues on ARM, patch from Jozsef Kadlecsik. 4) Fix bit check on bitmap in ipset hash type, also from Jozsef. 5) Release buckets when all entries have expired in ipset hash type, again from Jozsef. 6) Oneliner to initialize conntrack tuple object in the PPTP helper, otherwise the conntrack lookup may fail due to random bits in the structure holes, patch from Anthony Lineham. 7) Silence a bogus gcc warning in nfnetlink_log, from Arnd Bergmann. 8) Fix Kconfig dependency problems with TPROXY, socket and dup, also from Arnd. 9) Add __netdev_alloc_pcpu_stats() to allow creating percpu counters from atomic context, this is required by the follow up fix for nf_tables. 10) Fix crash from the dynamic set expression, we have to add new clone operation that should be defined when a simple memcpy is not enough. This resolves a crash when using per-cpu counters with new Patrick McHardy's flow table nft support. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Pull ARM SoC defconfig updates from Olof Johansson: "Defconfig updates are kept separate from other branches mostly to avoid conflicts between the different categories (driver branch enabling something that has context conflict with SoC options, etc). A lot of this again is scattered across the various hardware platforms. multi_v7_defconfig, our "generic" config for most 32-bit platforms has been gone through by Marvell Berlin maintainers and added most options they need to run on their hardware. Broadcom NSP is also added there, and the new Atmel SAMA5D2 (added last release). Rockchip also has display and other devices supported in that config. In addition to that, the usual small churn of new options being added here and there" * tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (45 commits) ARM: multi_v7_defconfig: enable UniPhier I2C drivers ARM: multi_v7_defconfig: Enable rtl8152 ethernet driver for Odroid-XU4 ARM: exynos_defconfig: Enable rtl8152 ethernet driver for Odroid-XU4 ARM: exynos_defconfig: Enable WiFi-Ex as a module instead built-in ARM: exynos_defconfig: Disable simplefb support ARM: exynos_defconfig: Enable LEDS for Odroid-XU3/XU4 ARM: multi_v7_defconfig: Enable DWC2 USB driver and USB ethernet gadget ARM: exynos_defconfig: Enable DWC2 USB driver and USB ethernet gadget ARM: exynos_defconfig: Enable USB Video Class support ARM: multi_v7_defconfig: improve multi_v7_defconfig support for Berlin ARM: tegra: Update multi_v7_defconfig ARM: multi_v7_defconfig: Add Atmel SDHCI device ARM: multi_v7_defconfig: Add Atmel Flexcom device ARM: multi_v7_defconfig: Add Atmel SAMA5D2 SoC ARM: at91/defconfig: add sama5d2 and its new devices to sama5 defconfig ARM: at91/defconfig: update at91_dt defconfig ARM: at91/defconfig: update sama5 defconfig ARM: configs: Enable FIXED_PHY in multi_v7 defconfig ARM: configs: update lpc18xx defconfig ARM: socfpga_defconfig: enable fpga manager ...
