Fixed a bug when creating file backing shared data (#963)
commit eff574d8862dacbc1922491c9166f26fa2b2eb9e
Author: Rohan Garg <rohgarg@ccs.neu.edu>
Date: Tue Apr 24 01:46:22 2018 -0400
Fix checkpoint-restore of file-backed regions
The issue is related to the fact that an application is allowed to
mmap a large region of memory even though the entire region may not be
backed by a file. For example, for a file that is just 1 MB on disk,
the application can make an mmap call asking for 2 GB, but only the
first 1 MB of the memory region will be actually made available. There
are two different behaviors of the Linux kernel when one tries to read
anything beyond the first 1 MB:
- If one tries to read any byte in user-land (load instruction) beyond the first
1 MB, it generates a SIGBUS.
- If one makes a system call such as write() that uses the entire memory
region (2 GB), the system call returns success, meaning that it wrote
2 GB, but it actually only writes out 1 MB!
Now, this confuses the restart code: since we recorded that the size
of the region is 2 GB, the code expects that the memory region would be
2 GB, but the kernel only wrote 1 MB. The code then tries to read 2 GB from
the image. There are two possible outcomes:
- Either the read fails (because of EOF), or
- The read succeeds (if the image had sufficient data). However, for the
subsequent memory region, we'll end up seeing garbage data.
Basically, the checkpoint image has all the checkpoint data but it's
not at the offsets that we are expecting.

Removed volatile from StackHead definition.
The __attribute((aligned)) causes the struct to grow beyond double-word,
causing CAS to fail. Since this field is updated in a safe manner, we
don't need it to be safe.

Handle workers that exec after PRESUSPEND.
Since user threads are not quiesced until after processing
DMTCP_PRESUSPEND event, a user thread might exec after receiving
DMT_DO_CHECKPOINT msg from the coordinator. After exec completes, the
process will wait for a new DMT_DO_CHECKPOINT msg while the coordinator
is waiting for all workers to reach the DMT:SUSPEND barrier.
The fix is to send a duplicate DMT_DO_CHECKPOINT message if a checkpoint
is in progress when a worker reconnects to the coordinator after exec.
We also handle the possibility of doing an exec even before receiving
DMT_DO_CHECKPOINT message. In that case, the worker will receive two
DMT_DO_CHECKPOINT messages and will safely ignore the second one.

Removed statically allocated strings.
Statically allocated string required at_exit/on_exit handlers to be
registered with libc. This can cause weird deadlocks because the
on_exit/at_exit handle registration requires manipulating libc-internal
linked lists with low-level libc locks and malloc/calloc/free calls.
If the static string is not getting initialized during checkpoint phase, a
deadlock is less likely. But during a checkpoint, the probability rises
significantly.
Added a wrapper for on_exit to ensure we don't checkpoint in the middle
of exit handler registration.

Fix to sporadic crash on restarted application
TLSInfo_GetTidOffset() sometimes calculates the wrong tid offset. When the function identifies the value is invalid, it returns a statically calculated one. However, the function still saves the invalid one for use later. This can cause subsequent mischief and segfaults in libc calls in the restarted function.
This change does not fix the original problem (wrong tid offset), but has the function at least retain the more sensible backup value when it finds the one it calculates is invalid.

mtcp_restart.c: fix vdso/vvar overlap w/ orig addr
* If vvar or vdso overlaps with their pre-checkpoint addresses, and
are not the same addresses, we now try to move vvar to original
address, if that does not create an address conflict. After that,
it must be safe to move vds0 to its original address.
* The FIXME comment describes how to fix this fully, by first moving
to a temporary address, but this is good enough for now. If an error
still occurs, the error message refers to this FIXME comment.
