2018-03-26asm-generic: clean up asm/unistd.hArnd Bergmann

2018-03-26asm-generic: siginfo: define ia64 si_codes unconditionallyArnd Bergmann
Unlike system call numbers the assignment of si_codes has never had a reason to be made per architecture. Some architectures have had unique conditions to report and reporting those conditions needed new si_codes. Nothing has ever needed si_codes to have different values on different architectures. The si_code space is vast so even with defining all si_codes on all architectures there is no danger in running out of si_code values. The history of the si_codes BUS_MCEERR_AR, BUS_MCEER_AO, SEGV_BNDERR, and SEGV_PKUERR show that a need of one architecture frequently becomes a need of another architecture which makes sharing si_codes between architectures a positive benefit and something to be encouraged. Where there are no conflicts with the historical ia64 arch specific si_codes and any other si_codes make them generic si_codes. We might need them on another architecture someday. This leaves only the good example of arch generic si_codes in the kernel for future architectures and architecture enhancments to follow. Without bad examples to follow it should be easy to avoid the mistakes of the past. Reported-by: Eric W.

2018-03-26of/Documentation: Specify local APIC ID in "reg"Ivan Gorinov
Use the "reg" property to specify the processor's local APIC ID instead of setting it to the CPU node index in Device Tree. Local APIC ID is assigned by hardware and visible in the APIC ID register. Some processor models allow APIC ID to be changed by software, but CPUID instruction executed with %eax = 0x0b always returns the initial ID in %edx. Local APIC ID does not match the node index in many systems.

2018-03-26pinctrl/amd: poll InterruptEnable bits in enable_irqDaniel Kurtz
In certain cases interrupt enablement will be delayed relative to when the InterruptEnable bits are written. One example of this is when a GPIO's "debounce" logice is first enabled. After enabling debounce, there is a 900 us "warm up" period during which InterruptEnable[0] (bit 11) will read as 0 despite being written 1. During this time InterruptSts will not be updated, nor will interrupts be delivered, even if the GPIO's interrupt configuration has been written to the register. To work around this delay, poll the InterruptEnable bits after setting them to ensure interrupts have truly been enabled in hardware before returning from the irq_enable handler.

2018-03-26bpf: Add bpf_verifier_vlog() and bpf_verifier_log_needed()Martin KaFai Lau
The BTF (BPF Type Format) verifier needs to reuse the current BPF verifier log. Hence, it requires the following changes: (1) Expose log_write() in verifier.c for other users. Its name is renamed to bpf_verifier_vlog(). (2) The BTF verifier also needs to check 'log->level && log->ubuf && !bpf_verifier_log_full(log);' independently outside of the current log_write(). It is because the BTF verifier will do one-check before making multiple calls to btf_verifier_vlog to log the details of a type. Hence, this check is also re-factored to a new function bpf_verifier_log_needed(). Since it is re-factored, we can check it before va_start() in the current bpf_verifier_log_write() and verbose().

2018-03-25ipv6: the entire IPv6 header chain must fit the first fragmentPaolo Abeni
While building ipv6 datagram we currently allow arbitrary large extheaders, even beyond pmtu size. The syzbot has found a way to exploit the above to trigger the following splat: kernel BUG at ./include/linux/skbuff.h:2073! invalid opcode: 0000 [#1] SMP KASAN Dumping ftrace buffer: (ftrace buffer empty) Modules linked in: CPU: 1 PID: 4230 Comm: syzkaller672661 Not tainted 4.16.0-rc2+ #326 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 RIP: 0010:__skb_pull include/linux/skbuff.h:2073 [inline] RIP: 0010:__ip6_make_skb+0x1ac8/0x2190 net/ipv6/ip6_output.c:1636 RSP: 0018:ffff8801bc18f0f0 EFLAGS: 00010293 RAX: ffff8801b17400c0 RBX: 0000000000000738 RCX: ffffffff84f01828 RDX: 0000000000000000 RSI: 0000000000000001 RDI: ffff8801b415ac18 RBP: ffff8801bc18f360 R08: ffff8801b4576844 R09: 0000000000000000 R10: ffff8801bc18f380 R11: ffffed00367aee4e R12: 00000000000000d6 R13: ffff8801b415a740 R14: dffffc0000000000 R15: ffff8801b45767c0 FS: 0000000001535880(0000) GS:ffff8801db300000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000000002000b000 CR3: 00000001b4123001 CR4: 00000000001606e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: ip6_finish_skb include/net/ipv6.h:969 [inline] udp_v6_push_pending_frames+0x269/0x3b0 net/ipv6/udp.c:1073 udpv6_sendmsg+0x2a96/0x3400 net/ipv6/udp.c:1343 inet_sendmsg+0x11f/0x5e0 net/ipv4/af_inet.c:764 sock_sendmsg_nosec net/socket.c:630 [inline] sock_sendmsg+0xca/0x110 net/socket.c:640 ___sys_sendmsg+0x320/0x8b0 net/socket.c:2046 __sys_sendmmsg+0x1ee/0x620 net/socket.c:2136 SYSC_sendmmsg net/socket.c:2167 [inline] SyS_sendmmsg+0x35/0x60 net/socket.c:2162 do_syscall_64+0x280/0x940 arch/x86/entry/common.c:287 entry_SYSCALL_64_after_hwframe+0x42/0xb7 RIP: 0033:0x4404c9 RSP: 002b:00007ffdce35f948 EFLAGS: 00000217 ORIG_RAX: 0000000000000133 RAX: ffffffffffffffda RBX: 00000000004002c8 RCX: 00000000004404c9 RDX: 0000000000000003 RSI: 0000000020001f00 RDI: 0000000000000003 RBP: 00000000006cb018 R08: 00000000004002c8 R09: 00000000004002c8 R10: 0000000020000080 R11: 0000000000000217 R12: 0000000000401df0 R13: 0000000000401e80 R14: 0000000000000000 R15: 0000000000000000 Code: ff e8 1d 5e b9 fc e9 15 e9 ff ff e8 13 5e b9 fc e9 44 e8 ff ff e8 29 5e b9 fc e9 c0 e6 ff ff e8 3f f3 80 fc 0f 0b e8 38 f3 80 fc <0f> 0b 49 8d 87 80 00 00 00 4d 8d 87 84 00 00 00 48 89 85 20 fe RIP: __skb_pull include/linux/skbuff.h:2073 [inline] RSP: ffff8801bc18f0f0 RIP: __ip6_make_skb+0x1ac8/0x2190 net/ipv6/ip6_output.c:1636 RSP: ffff8801bc18f0f0 As stated by RFC 7112 section 5: When a host fragments an IPv6 datagram, it MUST include the entire IPv6 Header Chain in the First Fragment. So this patch addresses the issue dropping datagrams with excessive extheader length. It also updates the error path to report to the calling socket nonnegative pmtu values. The issue apparently predates git history. v1 -> v2: cleanup error path, as per Eric's suggestion Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Reported-by: syzbot+91e6f9932ff122fa4410@syzkaller.appspotmail.com Signed-off-by: Paolo Abeni <pabeni@redhat.com> Reviewed-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
