            Bug ID: 140068
           Summary: [Linux] SeccompBrokerClient should cache arbitrary
                    file descriptors
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at igalia.com

If malloc() attempts to open /proc/sys/vm/overcommit_memory in a SIGSYS signal handler, the SeccompBroker will attempt to recursively broker the open() syscall. Generalize the existing code that already handles the similar case where malloc() opens /sys/devices/system/cpu/online to handle this situation as well.
