      kallsyms: Don't let kallsyms_lookup_size_offset() fail on retrieving the first symbol · 2a1a3fa0
      Marc Zyngier authored
      An arm64 kernel configured with
      
        CONFIG_KPROBES=y
        CONFIG_KALLSYMS=y
        # CONFIG_KALLSYMS_ALL is not set
        CONFIG_KALLSYMS_BASE_RELATIVE=y
      
      reports the following kprobe failure:
      
        [    0.032677] kprobes: failed to populate blacklist: -22
        [    0.033376] Please take care of using kprobes.
      
      It appears that kprobe fails to retrieve the symbol at address
      0xffff000010081000, despite this symbol being in System.map:
      
        ffff000010081000 T __exception_text_start
      
      This symbol is part of the first group of aliases in the
      kallsyms_offsets array (symbol names generated using ugly hacks in
      scripts/kallsyms.c):
      
        kallsyms_offsets:
                .long   0x1000 // do_undefinstr
                .long   0x1000 // efi_header_end
                .long   0x1000 // _stext
                .long   0x1000 // __exception_text_start
                .long   0x12b0 // do_cp15instr
      
      Looking at the implementation of get_symbol_pos(), it returns the
      lowest index for aliasing symbols. In this case, it return 0.
      
      But kallsyms_lookup_size_offset() considers 0 as a failure, which
      is obviously wrong (there is definitely a valid symbol living there).
      In turn, the kprobe blacklisting stops abruptly, hence the original
      error.
      
      A CONFIG_KALLSYMS_ALL kernel wouldn't fail as there is always
      some random symbols at the beginning of this array, which are never
      looked up via kallsyms_lookup_size_offset.
      
      Fix it by considering that get_symbol_pos() is always successful
      (which is consistent with the other uses of this function).

      openvswitch: Fix conntrack cache with timeout · 71778951
      Yi-Hung Wei authored
      This patch addresses a conntrack cache issue with timeout policy.
      Currently, we do not check if the timeout extension is set properly in the
      cached conntrack entry.  Thus, after packet recirculate from conntrack
      action, the timeout policy is not applied properly.  This patch fixes the
      aforementioned issue.

      fib_dump_info incorrectly has nhs = 0 for blackhole nexthops, so it
      believes the nexthop object is a multipath group (nhs != 1) and ends
      up down the nexthop_mpath_fill_node() path which is wrong for a
      blackhole.
      
      The blackhole check in nexthop_num_path is leftover from early days
      of the blackhole implementation which did not initialize the device.
      In the end the design was simpler (fewer special case checks) to set
      the device to loopback in nh_info, so the check in nexthop_num_path
      should have been removed.

      Pull x86 fixes from Thomas Gleixner:
       "A few fixes for x86:
      
         - Fix a boot regression caused by the recent bootparam sanitizing
           change, which escaped the attention of all people who reviewed that
           code.
      
         - Address a boot problem on machines with broken E820 tables caused
           by an underflow which ended up placing the trampoline start at
           physical address 0.
      
         - Handle machines which do not advertise a legacy timer of any form,
           but need calibration of the local APIC timer gracefully by making
           the calibration routine independent from the tick interrupt. Marked
           for stable as well as there seems to be quite some new laptops
           rolled out which expose this.
      
         - Clear the RDRAND CPUID bit on AMD family 15h and 16h CPUs which are
           affected by broken firmware which does not initialize RDRAND
           correctly after resume. Add a command line parameter to override
           this for machine which either do not use suspend/resume or have a
           fixed BIOS. Unfortunately there is no way to detect this on boot,
           so the only safe decision is to turn it off by default.
      
         - Prevent RFLAGS from being clobbers in CALL_NOSPEC on 32bit which
           caused fast KVM instruction emulation to break.
      
         - Explain the Intel CPU model naming convention so that the repeating
           discussions come to an end"
