2019-11-02blk-mq: avoid sysfs buffer overflow with too many CPU coresMing Lei
It is reported that sysfs buffer overflow can be triggered if the system has too many CPU cores(>841 on 4K PAGE_SIZE) when showing CPUs of hctx via /sys/block/$DEV/mq/$N/cpu_list. Use snprintf to avoid the potential buffer overflow. This version doesn't change the attribute format, and simply stops showing CPU numbers if the buffer is going to overflow.

2019-11-02KVM: x86: switch KVMCLOCK base to monotonic raw clockMarcelo Tosatti
Commit 0bc48bea36d1 ("KVM: x86: update master clock before computing kvmclock_offset") switches the order of operations to avoid the conversion TSC (without frequency correction) -> system_timestamp (with frequency correction), which might cause a time jump. However, it leaves any other masterclock update unsafe, which includes, at the moment: * HV_X64_MSR_REFERENCE_TSC MSR write. * TSC writes. * Host suspend/resume. Avoid the time jump issue by using frequency uncorrected CLOCK_MONOTONIC_RAW clock. Its the guests time keeping software responsability to track and correct a reference clock such as UTC. This fixes forward time jump (which can result in failure to bring up a vCPU) during vCPU hotplug: Oct 11 14:48:33 storage kernel: CPU2 has been hot-added Oct 11 14:48:34 storage kernel: CPU3 has been hot-added Oct 11 14:49:22 storage kernel: smpboot: Booting Node 0 Processor 2 APIC 0x2 <-- time jump of almost 1 minute Oct 11 14:49:22 storage kernel: smpboot: do_boot_cpu failed(-1) to wakeup CPU#2 Oct 11 14:49:23 storage kernel: smpboot: Booting Node 0 Processor 3 APIC 0x3 Oct 11 14:49:23 storage kernel: kvm-clock: cpu 3, msr 0:7ff640c1, secondary cpu clock Which happens because: /* * Wait 10s total for a response from AP */ boot_error = -1; timeout = jiffies + 10*HZ; while (time_before(jiffies, timeout)) { ... } Analyzed-by: Igor Mammedov <imammedo@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2019-11-02powerpc/bpf: Fix tail call implementationEric Dumazet
We have seen many crashes on powerpc hosts while loading bpf programs. The problem here is that bpf_int_jit_compile() does a first pass to compute the program length. Then it allocates memory to store the generated program and calls bpf_jit_build_body() a second time (and a third time later) What I have observed is that the second bpf_jit_build_body() could end up using few more words than expected. If bpf_jit_binary_alloc() put the space for the program at the end of the allocated page, we then write on a non mapped memory. It appears that bpf_jit_emit_tail_call() calls bpf_jit_emit_common_epilogue() while ctx->seen might not be stable. Only after the second pass we can be sure ctx->seen wont be changed. Trying to avoid a second pass seems quite complex and probably not worth it.

2019-11-01net: fix installing orphaned programsJakub Kicinski
When netdevice with offloaded BPF programs is destroyed the programs are orphaned and removed from the program IDA - their IDs get released (the programs may remain accessible via existing open file descriptors and pinned files). After IDs are released they are set to 0. This confuses dev_change_xdp_fd() because it compares the __dev_xdp_query() result where 0 means no program with prog->aux->id where 0 means orphaned. dev_change_xdp_fd() would have incorrectly returned success even though it had not installed the program. Since drivers already catch this case via bpf_offload_dev_match() let them handle this case. The error message drivers produce in this case ("program loaded for a different device") is in fact correct as the orphaned program must had to be loaded for a different device.

2019-11-01inet: stop leaking jiffies on the wireEric Dumazet
Historically linux tried to stick to RFC 791, 1122, 2003 for IPv4 ID field generation. RFC 6864 made clear that no matter how hard we try, we can not ensure unicity of IP ID within maximum lifetime for all datagrams with a given source address/destination address/protocol tuple. Linux uses a per socket inet generator (inet_id), initialized at connection startup with a XOR of 'jiffies' and other fields that appear clear on the wire. Thiemo Nagel pointed that this strategy is a privacy concern as this provides 16 bits of entropy to fingerprint devices. Let's switch to a random starting point, this is just as good as far as RFC 6864 is concerned and does not leak anything critical.

Lyude Paul fixes an issue where a fatal read error occurs when the device is unplugged from the machine. So change the read error into a warn while the device is still present. Manfred Rudigier found that the i350 device was not apart of the "Media Auto Sense" feature, yet the device supports it. So add the missing i350 device to the check and fix an issue where the media auto sense would flip/flop when no cable was connected to the port causing spurious kernel log messages. I fixed an issue where the fix to resolve receive buffer starvation was applied in more than one place in the driver, one being the incorrect location in the i40e driver. Wenwen Wang fixes a potential memory leak in e1000 where allocated memory is not properly cleaned up in one of the error paths. Jonathan Neuschäfer cleans up the driver documentation to be consistent and remove the footnote reference, since the footnote no longer exists in the documentation.

2019-11-01MIPS: Fork loongson2ef from loongson64Jiaxun Yang
As later model of GSx64 family processors including 2-series-soc have similar design with initial loongson3a while loongson2e/f seems less identical, we separate loongson2e/f support code out of mach-loongson64 to make our life easier. This patch contains mostly file moving works.

2019-11-01i40e: Fix receive buffer starvation for AF_XDPJeff Kirsher
Magnus's fix to resolve a potential receive buffer starvation for AF_XDP got applied to both the i40e_xsk_umem_enable/disable() functions, when it should have only been applied to the "enable". So clean up the undesired code in the disable function.

2019-11-01igb: Fix constant media auto sense switching when no cable is connectedManfred Rudigier
At least on the i350 there is an annoying behavior that is maybe also present on 82580 devices, but was probably not noticed yet as MAS is not widely used. If no cable is connected on both fiber/copper ports the media auto sense code will constantly swap between them as part of the watchdog task and produce many unnecessary kernel log messages. The swap code responsible for this behavior (switching to fiber) should not be executed if the current media type is copper and there is no signal detected on the fiber port. In this case we can safely wait until the AUTOSENSE_EN bit is cleared.
