From man TIOCPKT:
"""
In packet mode, each subsequent read(2) will return a packet that either
contains a single nonzero control byte, or has a single byte containing zero
('\0') followed by data written on the slave side of the pseudoterminal."
"""
This CL implements only the data portion of packet mode, not the control bytes,
but that seems to be enough to get xfce4-terminal to work.

Currently, the NoSigBusOnPagesBeforeEOF and NoSigBusOnPageContainingEOF
test cases are identical. This patch corrects the addr accessed in the
former test to match the corresponding comment.

This can be used by all test users. Avoids duplicated code. We can handle all
known issues in one place.
There is a Docker bug which causes restore to fail sporadically. See
https://github.com/moby/moby/issues/42900. This has been broken at least since
Docker v19.03.12 (when the issue was reported) and was fixed in v25.0.4. Added
the handling for this issue.
Also got rid of the testutil.Poll() around restore. That can hide gVisor
restore flakiness issues. That was added in 0990ef7517 ("Make
checkpoint/restore e2e test less flaky"). The original sleep has been restored.

This support is only needed when the gofer mount in question is writable.
By default, the rootfs has an overlayfs applied, so the gofer lower layer is
not writabled. But if you are using --overlay2=none, then this change should
allow you to save sandbox with open FDs to deleted files in rootfs.

Add image for ARM workloads for cuda-tests and mark tests that work on ARM.
Most tests don't work due to cross-compiling between sbma and aarch64.
However, a few do. Add an image to support them.
From setpgid manpage,
EACCES - An attempt was made to change the process group ID of one
of the children of the calling process and the child had
already performed an execve(2) (setpgid(), setpgrp()).
This CL makes gVisor implement this rule and updates the exec test
suite accordingly.

`fdBitmap.FirstZero()` could return `max` value; if it does, then
recompute the max value to avoid reusing the old max value twice.
The default bitmap size for file descriptors in gVisor is 65535.
Add a pipe test that attempts to create more than 65535 FDs to hit the edge
case where fdBitmap.FirstZero() returns the default bitmap max value of 65535.

AllSocketPairTest.SetAndGetBooleanSocketOptions fails on the upstream linux
kernel. The behaviour has been changed by 5b0af621c3f6 ("net: restrict
SO_REUSEPORT to inet sockets").
