2019-07-02Remove map from fd_map, change to fd_table.Adin Scannell
This renames FDMap to FDTable and drops the kernel.FD type, which had an entire package to itself and didn't serve much use (it was freely cast between types, and served as more of an annoyance than providing any protection.) Based on BenchmarkFDLookupAndDecRef-12, we can expect 5-10 ns per lookup operation, and 10-15 ns per concurrent lookup operation of savings. This also fixes two tangential usage issues with the FDMap. Namely, non-atomic use of NewFDFrom and associated calls to Remove (that are both racy and fail to drop the reference on the underlying file.) PiperOrigin-RevId: 256285890
2019-07-02sentry/kernel: add syslog messageAhmet Alp Balkan
It feels like "reticulating splines" is missing from the list of meaningless syslog messages. Signed-off-by: Ahmet Alp Balkan <ahmetb@google.com>

2019-06-27Complete pipe support on overlayfsFabricio Voznika
Get/Set pipe size and ioctl support were missing from overlayfs. It required moving the pipe.Sizer interface to fs so that overlay could get access. Fixes #318 PiperOrigin-RevId: 255511125

2019-06-25gvisor: lockless read access for task credentialsAndrei Vagin
Credentials are immutable and even before these changes we could read them without locks, but we needed to take a task lock to get a credential object from a task object. It is possible to avoid this lock, if we will guarantee that a credential object will not be changed after setting it on a task. PiperOrigin-RevId: 254989492

2019-06-19Add MountNamespace to task.Nicolas Lacasse
This allows tasks to have distinct mount namespace, instead of all sharing the kernel's root mount namespace. Currently, the only way for a task to get a different mount namespace than the kernel's root is by explicitly setting a different MountNamespace in CreateProcessArgs, and nothing does this (yet). In a follow-up CL, we will set CreateProcessArgs.MountNamespace when creating a new container inside runsc. Note that "MountNamespace" is a poor term for this thing. It's more like a distinct VFS tree. When we get around to adding real mount namespaces, this will need a better naem. PiperOrigin-RevId: 254009310
