2021-09-30kernel: print PID in addition to TID in task log messagesAndrei Vagin
For multithreads processes, it is hard to read logs without knowing task pids. And let's print a decimal return codeo for syscalls. A hex return code are usefull for system calls that return addresses. For other syscalls, the decimal form is more readable. PiperOrigin-RevId: 400035449

2021-09-27Prevent PacketData from being modified.Ayush Ranjan
PacketData should not be modified and should be treated readonly because it represents packet payload. The old DeleteFront method allowed callers to modify the underlying buffer which should not be allowed. Added a way to consume from the PacketData instead of deleting from it. Updated call points to use that instead. Reported-by: syzbot+faee5cb350f769a52d1b@syzkaller.appspotmail.com PiperOrigin-RevId: 399268473

2021-09-23Allow lisafs client to send more data than MaxMessageSize using chunks.Ayush Ranjan

2021-09-23Create the cgroupfs mount point in sysfs.Rahat Mahmood
Create the /sys/fs/cgroup directory when cgroups are available. This creates the empty directory to serve as the mountpoint, actually mounting cgroups is left to the launcher/userspace. This is consistent with Linux behaviour. Without this mountpoint, getdents(2) on /sys/fs indicates an empty directory even if the launcher mounts cgroupfs at /sys/fs/cgroup. The launcher can't create the mountpoint directory since sysfs doesn't support mkdir. PiperOrigin-RevId: 398596698
