2018-11-15Advertise vsyscall support via /proc/<pid>/maps.Rahat Mahmood
Also update test utilities for probing vsyscall support and add a metric to see if vsyscalls are actually used in sandboxes. PiperOrigin-RevId: 221698834 Change-Id: I57870ecc33ea8c864bd7437833f21aa1e8117477
2018-10-20Add more unimplemented syscall eventsFabricio Voznika
Added events for *ctl syscalls that may have multiple different commands. For runsc, each syscall event is only logged once. For *ctl syscalls, use the cmd as identifier, not only the syscall number. PiperOrigin-RevId: 218015941 Change-Id: Ie3c19131ae36124861e9b492a7dbe1765d9e5e59
2018-10-17Check thread group CPU timers in the CPU clock ticker.Jamie Liu
This reduces the number of goroutines and runtime timers when ITIMER_VIRTUAL or ITIMER_PROF are enabled, or when RLIMIT_CPU is set. This also ensures that thread group CPU timers only advance if running tasks are observed at the time the CPU clock advances, mostly eliminating the possibility that a CPU timer expiration observes no running tasks and falls back to the group leader.

2018-10-08Implement shared futexes.Jamie Liu
- Shared futex objects on shared mappings are represented by Mappable + offset, analogous to Linux's use of inode + offset. Add type futex.Key, and change the futex.Manager bucket API to use futex.Keys instead of addresses. - Extend the futex.Checker interface to be able to return Keys for memory mappings. It returns Keys rather than just mappings because whether the address or the target of the mapping is used in the Key depends on whether the mapping is MAP_SHARED or MAP_PRIVATE; this matters because using mapping target for a futex on a MAP_PRIVATE mapping causes it to stop working across COW-breaking. - futex.Manager.WaitComplete depends on atomic updates to futex.Waiter.addr to determine when it has locked the right bucket, which is much less straightforward for struct futex.Waiter.key. Switch to an atomically-accessed futex.Waiter.bucket pointer. - futex.Manager.Wake now needs to take a futex.Checker to resolve addresses for shared futexes. CLONE_CHILD_CLEARTID requires the exit path to perform a shared futex wakeup (Linux: kernel/fork.c:mm_release() => sys_futex(tsk->clear_child_tid, FUTEX_WAKE, ...)). This is a problem because futexChecker is in the syscalls/linux package. Move it to kernel. PiperOrigin-RevId: 216207039 Change-Id: I708d68e2d1f47e526d9afd95e7fed410c84afccf
2018-09-04Distinguish Element and Linker for ilist.Adin Scannell
Furthermore, allow for the specification of an ElementMapper. This allows a single "Element" type to exist on multiple inline lists, and work without having to embed the entry type. This is a requisite change for supporting a per-Inode list of Dirents. PiperOrigin-RevId: 211467497 Change-Id: If2768999b43e03fdaecf8ed15f435fe37518d163
2018-08-31Disintegrate kernel.TaskResources.Jamie Liu
This allows us to call kernel.FDMap.DecRef without holding mutexes cleanly. PiperOrigin-RevId: 211139657 Change-Id: Ie59d5210fb9282e1950e2e40323df7264a01bcec
