Otherwise a copy happens, which triggers a data race when reading
masterInodeOperations.SimpleFileOperations.uattr, which must be accessed with a
lock held.

Add checks for input arguments, file type, permissions, etc. that match
the Linux implementation. A call to get/setxattr that passes all the
checks will still currently return EOPNOTSUPP. Actual support will be
added in following commits.
Only allow user.* extended attributes for the time being.

Copy up parent when binding UDS on overlayfs is supported in commit
02ab1f187cd24c67b754b004229421d189cee264.
But the using of copyUp in overlayBind will cause sentry stuck, reason
is dead lock in renameMu.
1 [Process A] Invoke a Unix socket bind operation
renameMu is hold in fs.(*Dirent).genericCreate by process A
2 [Process B] Invoke a read syscall on /proc/task/mounts
waitng on Lock of renameMu in fs.(*MountNamespace).FindMount
3 [Process A] Continue Unix socket bind operation
wating on RLock of renameMu in fs.copyUp
Root cause is recursive reading lock of reanmeMu in bind call trace,
if there are writing lock between the two reading lock, then deadlock
occured.
Fixes #1397

After the finalizer optimize in 76039f895995c3fe0deef5958f843868685ecc38
commit, clientFile needs to closed before finalizer release it.
The clientFile is not closed if it is created via
gofer.(*inodeOperations).Bind, this will cause fd leak which is hold
by gofer process.
Fixes #1396

The implementation follows the linux behavior where specifying
a TCP_USER_TIMEOUT will cause the resend timer to honor the
user specified timeout rather than the default rto based timeout.
Further it alters when connections are timedout due to keepalive
failures. It does not alter the behavior of when keepalives are
sent. This is as per the linux behavior.

The former is needed for vfs.FileDescription to implement
memmap.MappingIdentity, and the latter is needed to implement getcwd(2).

runsc debug --ps list all processes with all threads. This option is added to
the debug command but not to the ps command, because it is going to be used for
debug purposes and we want to add any useful information without thinking about
backward compatibility.
This will help to investigate syzkaller issues.

Also, improve performance by calculating how much space is needed before making
an allocation for sendmsg in hostinet.

Package strace is missing some syscalls we actually implement (e.g.,
getrandom). We also see newer syscalls sometimes (e.g., membarrier) that would
be handy to have formatted.
Let's go ahead and add all syscalls in the latest upstream release (v5.4), even
though we only intend to implement v4.4. None of them are implemented, just
included as placeholders.
