When user space sends invalid information in RTA_MULTIPATH, the nexthop list in ip6_route_multipath_add() is empty and 'rt_notif' is set to NULL. The code that emits the in-kernel notifications does not check for this condition, which results in a NULL pointer dereference [1]. Fix this by bailing earlier in the function if the parsed nexthop list is empty. This is consistent with the corresponding IPv4 code. v2: * Check if parsed nexthop list is empty and bail with extack set [1] kasan: CONFIG_KASAN_INLINE enabled kasan: GPF could be caused by NULL-ptr deref or user memory access general protection fault: 0000 [#1] PREEMPT SMP KASAN CPU: 0 PID: 9190 Comm: syz-executor149 Not tainted 5.2.0-rc5+ #38 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 RIP: 0010:call_fib6_multipath_entry_notifiers+0xd1/0x1a0 net/ipv6/ip6_fib.c:396 Code: 8b b5 30 ff ff ff 48 c7 85 68 ff ff ff 00 00 00 00 48 c7 85 70 ff ff ff 00 00 00 00 89 45 88 4c 89 e0 48 c1 e8 03 4c 89 65 80 <42> 80 3c 28 00 0f 85 9a 00 00 00 48 b8 00 00 00 00 00 fc ff df 4d RSP: 0018:ffff88809788f2c0 EFLAGS: 00010246 RAX: 0000000000000000 RBX: 1ffff11012f11e59 RCX: 00000000ffffffff RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000000 RBP: ffff88809788f390 R08: ffff88809788f8c0 R09: 000000000000000c R10: ffff88809788f5d8 R11: ffff88809788f527 R12: 0000000000000000 R13: dffffc0000000000 R14: ffff88809788f8c0 R15: ffffffff89541d80 FS: 000055555632c880(0000) GS:ffff8880ae800000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000020000080 CR3: 000000009ba7c000 CR4: 00000000001406f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: ip6_route_multipath_add+0xc55/0x1490 net/ipv6/route.c:5094 inet6_rtm_newroute+0xed/0x180 net/ipv6/route.c:5208 rtnetlink_rcv_msg+0x463/0xb00 net/core/rtnetlink.c:5219 netlink_rcv_skb+0x177/0x450 net/netlink/af_netlink.c:2477 rtnetlink_rcv+0x1d/0x30 net/core/rtnetlink.c:5237 netlink_unicast_kernel net/netlink/af_netlink.c:1302 [inline] netlink_unicast+0x531/0x710 net/netlink/af_netlink.c:1328 netlink_sendmsg+0x8ae/0xd70 net/netlink/af_netlink.c:1917 sock_sendmsg_nosec net/socket.c:646 [inline] sock_sendmsg+0xd7/0x130 net/socket.c:665 ___sys_sendmsg+0x803/0x920 net/socket.c:2286 __sys_sendmsg+0x105/0x1d0 net/socket.c:2324 __do_sys_sendmsg net/socket.c:2333 [inline] __se_sys_sendmsg net/socket.c:2331 [inline] __x64_sys_sendmsg+0x78/0xb0 net/socket.c:2331 do_syscall_64+0xfd/0x680 arch/x86/entry/common.c:301 entry_SYSCALL_64_after_hwframe+0x49/0xbe RIP: 0033:0x4401f9 Code: 18 89 d0 c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 0f 83 fb 13 fc ff c3 66 2e 0f 1f 84 00 00 00 00 RSP: 002b:00007ffc09fd0028 EFLAGS: 00000246 ORIG_RAX: 000000000000002e RAX: ffffffffffffffda RBX: 00000000004002c8 RCX: 00000000004401f9 RDX: 0000000000000000 RSI: 0000000020000080 RDI: 0000000000000003 RBP: 00000000006ca018 R08: 0000000000000000 R09: 00000000004002c8 R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000401a80 R13: 0000000000401b10 R14: 0000000000000000 R15: 0000000000000000 Reported-by: syzbot+382566d339d52cd1a204@syzkaller.appspotmail.com Fixes: ebee3cad ("ipv6: Add IPv6 multipath notifications for add / replace") Signed-off-by:

Some changes to the TCP fastopen code to make it more robust against future changes in the choice of key/cookie size, etc. - Instead of keeping the SipHash key in an untyped u8[] buffer and casting it to the right type upon use, use the correct type directly. This ensures that the key will appear at the correct alignment if we ever change the way these data structures are allocated. (Currently, they are only allocated via kmalloc so they always appear at the correct alignment) - Use DIV_ROUND_UP when sizing the u64[] array to hold the cookie, so it is always of sufficient size, even if TCP_FASTOPEN_COOKIE_MAX is no longer a multiple of 8. - Drop the 'len' parameter from the tcp_fastopen_reset_cipher() function, which is no longer used. - Add endian swabbing when setting the keys and calculating the hash, to ensure that cookie values are the same for a given key and source/destination address pair regardless of the endianness of the server. Note that none of these are functional changes wrt the current state of the code, with the exception of the swabbing, which only affects big endian systems. Signed-off-by:

Heiner Kallweit says: ==================== PCI: let pci_disable_link_state propagate errors Drivers like r8169 rely on pci_disable_link_state() having disabled certain ASPM link states. If OS can't control ASPM then pci_disable_link_state() turns into a no-op w/o informing the caller. The driver therefore may falsely assume the respective ASPM link states are disabled. Let pci_disable_link_state() propagate errors to the caller, enabling the caller to react accordingly. I'd propose to let this series go through the netdev tree if the PCI core extension is acked by the PCI people. ==================== Signed-off-by:

Certain chip version / board combinations have massive problems if ASPM is active. If BIOS enables ASPM and doesn't let OS control it, then we may have a problem with the current code. Therefore check the return code of pci_disable_link_state() and don't enable ASPM in the network chip if OS can't control ASPM. Signed-off-by:

tcp_fragment() might be called for skbs in the write queue. Memory limits might have been exceeded because tcp_sendmsg() only checks limits at full skb (64KB) boundaries. Therefore, we need to make sure tcp_fragment() wont punish applications that might have setup very low SO_SNDBUF values.

Pull rdma fixes from Doug Ledford: "This is probably our last -rc pull request. We don't have anything else outstanding at the moment anyway, and with the summer months on us and people taking trips, I expect the next weeks leading up to the merge window to be pretty calm and sedate. This has two simple, no brainer fixes for the EFA driver. Then it has ten not quite so simple fixes for the hfi1 driver. The problem with them is that they aren't simply one liner typo fixes. They're still fixes, but they're more complex issues like livelock under heavy load where the answer was to change work queue usage and spinlock usage to resolve the problem, or issues with orphaned requests during certain types of failures like link down which required some more complex work to fix too. They all look like legitimate fixes to me, they just aren't small like I wish they were.

GCC 5.5.0 sometimes cleverly hoists reads of the pvclock and/or hvclock pages before the vclock mode checks. This creates a path through vclock_gettime() in which no vclock is enabled at all (due to disabled TSC on old CPUs, for example) but the pvclock or hvclock page nevertheless read. This will segfault on bare metal. This fixes commit 459e3a21 ("gcc-9: properly declare the {pv,hv}clock_page storage") in the sense that, before that commit, GCC didn't seem to generate the offending code. There was nothing wrong with that commit per se, and -stable maintainers should backport this to all supported kernels regardless of whether the offending commit was present, since the same crash could just as easily be triggered by the phase of the moon. On GCC 9.1.1, this doesn't seem to affect the generated code at all, so I'm not too concerned about performance regressions from this fix.

Jon Hunter reports: "I have been noticing intermittent failures with a system suspend test on some of our machines that have a NFS mounted root file-system. Bisecting this issue points to your commit 43123581 ("SUNRPC: Declare RPC timers as TIMER_DEFERRABLE") and reverting this on top of v5.2-rc3 does appear to resolve the problem. The cause of the suspend failure appears to be a long delay observed sometimes when resuming from suspend, and this is causing our test to timeout." This reverts commit 43123581. Reported-by:

We can end up in nfs4_opendata_alloc during task exit, in which case current->fs has already been cleaned up. This leads to a crash in current_umask(). Fix this by only setting creation opendata if we are actually doing an open with O_CREAT. We can drop the check for NULL nfs4_open_createattrs, since O_CREAT will never be set for the recovery path.

On fix for the high-bandwidth backdoor port which is cc'd stable due to upcoming hardware, on which the code would otherwise break. Signed-off-by:

The commit fe00e50b ("ARM: 8858/1: vdso: use $(LD) instead of $(CC) to link VDSO") removed the passing of CFLAGS, since ld doesn't take those directly. However, prior, big-endian ARM was relying on gcc to translate its -mbe8 option into ld's --be8 option. Lacking this, ld generated be32 code, making the VDSO generate SIGILL when called by userspace. This commit passes --be8 if CONFIG_CPU_ENDIAN_BE8 is enabled. Signed-off-by:

Commit 332d0797 ("KVM: nVMX: KVM_SET_NESTED_STATE - Tear down old EVMCS state before setting new state", 2019-05-02) broke evmcs_test because the eVMCS setup must be performed even if there is no VMXON region defined, as long as the eVMCS bit is set in the assist page. While the simplest possible fix would be to add a check on kvm_state->flags & KVM_STATE_NESTED_EVMCS in the initial "if" that covers kvm_state->hdr.vmx.vmxon_pa == -1ull, that is quite ugly. Instead, this patch moves checks earlier in the function and conditionalizes them on kvm_state->hdr.vmx.vmxon_pa, so that vmx_set_nested_state always goes through vmx_leave_nested and nested_enable_evmcs.
