* sys/linux: prohibit EXT4_IOC_RESIZE_FSDmitry Vyukov2019-02-081-3/+2
| | | | | | | | | | | | | | | When we run with sandbox=none, test program can do EXT4_IOC_RESIZE_FS which shrinks rootfs basically to 0. This breaks the machine as all tests then fail with: failed to create temp dir: mkdir syzkaller-testdir077269498: no space left on device This is the most common source of "lost connection" crashes overall and they are not actually kernel bugs. Prohibit EXT4_IOC_RESIZE_FS for now. Alternatively we can mount tmpfs with sandbox=none. Update #971

| | | | EXT4_IOC_SHUTDOWN EXT4_IOC_SHUTDOWN on root fs effectively brings the machine down in weird ways.
* sys/linux: add ext4 ioctls and overlayfsDmitry Vyukov2018-08-291-0/+39
