I'm stuck figuring out why the CRIU dump process fails at Error (criu/files-reg.c:1815): Can't lookup mount=14 for fd=3 path=/secretmem (deleted). I think, lookup_mnt_id() fails due to this line.

Hi @warusadura

problem is that this execution path is wrong. For some reason during processing of memfd_secretfd you are getting into the regfile_dump_ops->dump op. But that's wrong, of course you need to handle memfd_secret file separately as it's done for memfd.

For example, read

criu/criu/memfd.c

Line 189 in 4f3d6e6

const struct fdtype_ops memfd_dump_ops = {

Another point of interest for you is this place:

criu/criu/files.c

Line 565 in 4f3d6e6

ops = &memfd_dump_ops;

here we assigning a proper dump callback ops depending on the file descriptor type.

Now about mounts and why you are getting this error. It's a implementation detail of a linux kernel, almost any types of a file descriptors in Linux kernel has some filesystem under the hood. For regular files it can be xfs, ext4, btrfs, ntfs and so on, for sockets it is sockfs, for pipes it is pipefs, for block devices it is bdev. But you can't mount pipefs, sockfs or bdev by yourself. It's kind of a magic filesystems (and hidden mounts) those are only existing behind the scene and that's why you can't see them in cat /proc/<pid>/mountinfo. memfd_secret file descriptors are not an exclusion from this rule, there is a secretmem_fs magic filesystem. But you can't mount it directly and it's not shown in the mountinfo file. That's why you can get mnt_id for it but you can't find any signs of it's existence in your system except this.

thanks @mihalicyn

warusadura · 2023-06-05T11:04:21Z

@mihalicyn @rppt

I'm trying to implement a similar function to the following, for memfd_secret

memfd:

int is_memfd(dev_t dev)
{
	return dev == kdat.shmem_dev;
}

I can't figure out the reason behind this comparison: dev == kdat.shmem_dev;

memfd_secret:

int is_memfd_secret(dev_t dev)
{
        pr_debug("======= now at: is_memfd_secret()\n");
        pr_debug("======= dev: %ld kdat.shmem_dev: %ld\n", dev, kdat.shmem_dev);
        /* struct kerndat_s */
	return dev == kdat.shmem_dev;
}

And in memfd_secret implementation, dev is never equal to kdat.shmem_dev, not sure why.

(00.013929) ======= now at: is_memfd_secret()
(00.013936) ======= dev: 13 kdat.shmem_dev: 1

I can't figure out the reason behind this comparison: dev == kdat.shmem_dev;

reason of this comparison is to determine if this particular file descriptor is the memfd file descriptor or not.

As you can see from this code

criu/criu/files.c

Line 564 in 4f3d6e6

    
           if (is_memfd(p.stat.st_dev) || (kdat.has_memfd_hugetlb && is_hugetlb_dev(p.stat.st_dev, NULL)))

we are using it to ops with corresponding value memfd_dump_ops.

Each file descriptor in Linux kernel is unique somehow. For example, if you have a pipe/fifo fd then you can easily distinguish it just by doing fstat syscall and checking S_ISFIFO(p.stat.st_mode) condition. But memfd from the fstat point of view looks like a "regular file", because S_ISREG(p.stat.st_mode) == true for it. As you can see:

	if (S_ISREG(p.stat.st_mode) || S_ISDIR(p.stat.st_mode) || S_ISLNK(p.stat.st_mode)) {
		if (fill_fdlink(lfd, &p, &link))
			return -1;

		p.link = &link;

		/* TODO: Dump for hugetlb fd when memfd hugetlb is not supported */
		if (is_memfd(p.stat.st_dev) || (kdat.has_memfd_hugetlb && is_hugetlb_dev(p.stat.st_dev, NULL)))
			ops = &memfd_dump_ops;

in the memfd case we have managed to find a proper way to distinguish it from other file descriptors those are look like a "regular files". We are doing it by checking p.stat.st_dev and comparing it with the fake block device dev_t that created by the kernel for shmem. Most likely you are a little bit surprised about this connection, but it follows from this:

memfd_create allocates a new fd in the kernel, it also prepared an inode for memfd file, any inode in the kernel assigned to some superblock, and any superblock is connected with some device. For regular filesystems (like ext4, xfs, fat, etc) this device is a block device where data is stored, but for virtual filesystems like memfd, pipefd, etc this device is a virtual device and it's not used to store any data. But it's still useful, for instance to determine if two files are from the same device or not. You can be sure that two fd's are pointing to the same file if they devices is the same and the inode number is the same.

As you can see from the CRIU code:

criu/criu/kerndat.c

Line 227 in 4f3d6e6

map = mmap(NULL, PAGE_SIZE, PROT_READ | PROT_WRITE, MAP_SHARED | MAP_ANONYMOUS, 0, 0);
criu/criu/kerndat.c

Line 237 in 4f3d6e6

kdat.shmem_dev = dev;

we just open a memfd descriptor and then saving st_dev from struct stat. So we can use it later to determine all the memfd files just by using a comparison between s_dev.

thank you very much @mihalicyn .

mihalicyn · 2023-06-05T11:43:15Z

So @warusadura please try to follow a code path for memfd_secret syscall as I did it for memfd_create. You will end up on this:
https://github.com/torvalds/linux/blob/9561de3a55bed6bdd44a12820ba81ec416e705a7/mm/secretmem.c#L284

so, technically you need to do the same thing as we did for memfd, but device node will be different.

warusadura · 2023-06-06T09:01:49Z

@mihalicyn @rppt

why do we set the kdat.has_memfd = true; here when the system call fails and errno is set to EFAULT?

mihalicyn · 2023-06-06T09:18:49Z

@mihalicyn @rppt

why do we set the kdat.has_memfd = true; here when the system call fails and errno is set to EFAULT?

because EFAULT is a correct value that memfd_create syscall returns when the first argument is a non-valid memory address (like NULL). And if memfd_create syscall is implemented it will work like that.

warusadura · 2023-06-07T10:57:11Z

@mihalicyn I have implemented the helper function: kerndat_has_memfd_create() to run during kerndat_init() and it work! And now kdat.has_memfd_secret.

But, I'm still stuck at properly implementing the is_memfd_secret() and related functionality. I'm still getting dev not being equal to kdat.shmem_dev;

(00.016079) ======= now at: is_memfd_secret()
(00.016084) ======= dev: 13 kdat.shmem_dev: 1

In memfd case, I have found that, both dev and kdat.shmem_dev is set to 1.

With memfd_secret case dev or device id is 13 and kdat.shmem_dev is 1. How can I get these two to be equal?

Also, where can I found the following,

we just open a memfd descriptor and then saving st_dev from struct stat. So we can use it later to determine all the memfd files just by using a comparison between s_dev.

they shouldn't be equal. for memfd_secret you should have kdat.memfd_secret_dev thing. Read my explanation here #2188 (comment) again. I believe that I've described everything with a good details. Feel free to ask specific questions regarding my explanation but try to read through the code and experiment with it before asking.

I have implemented the kerndat_get_memfd_secret_dev() that creates a fake dev_t device by the kernel for secretmem during kerndat_init(). And it works as expected \o/

Now I'm currently implementing the dump_one_memfd_secret().

Since memfd_secret syscall creates a fd (that points to secretmem), there should be an inode for that fd. Based on struct memfd_dump_inode, I have created the following for memfd_secret,

struct memfd_secret_dump_inode {
        struct list_head list; // don't know what this is
        u32 id; // don't know what this is
        u32 dev; // device where inode resides
        u32 ino; // actual inode id perhaps
};

Should there be more member for struct memfd_secret_dump?

Also, when we talk about inodes related to criu dump we are only concerned about the inodes for the contents of /proc/dumpee_id/fdinfo/ right? Surprisingly, the contents of /proc/dumpee_id/map_files/ also have inodes :)

Great!

I don't know, try to understand from the existing memfd code why we have these fields and whats the purpose of them ;-)

I'm not sure that I understand question, but generally we don't care about inode numbers, but we care about inodes content (file content).

Self-control question: why do we need struct memfd_dump_inode -> ino field. What's the purpose of it?
Useful experiment: try to checkpoint/restore memfd (not memfd_secret) and check what happens with an inode number after Checkpoint/Restore. Does it keep the same or changes? Why?

Also, related to implementation of dump_one_memfd_secret(), I have updated (following existing code) images/fdinfo.proto and created images/memfd-secret.proto based on memfd implementations. But, I don't know what these files are for. How can I learn about them?

line: fd = open_proc(PROC_SELF, "fd/%d", lfd); causing this error and lfd argument is the root cause. When experimented with literal constant values such as 3, 4, ... instead of lfd here, this line works!

How can set an appropriate value for lfd?
Also, what is represented by lfd? file descriptors list?

I think the origin of lfd comes from here

mihalicyn · 2023-06-13T14:19:43Z

Hi @warusadura!

Have you managed to understand from where list argument in list_for_each_entry macro comes from?
Can you write a few words about it?

How can set an appropriate value for lfd?

You don't need to set any value to lfd, it is passed to the ->dump callback from here:

criu/criu/files.c

Line 342 in 4d137b8

ret = ops->dump(lfd, e->id, p);

and it's the index of a file descriptor to dump.

Most likely you are getting ENXIO error because there is no struct file_operations ->open callback defined for memfd_secret FDs in the Linux kernel. It's just not supported.
So, the question is, do we really need to reopen file descriptor to memfd_secret if we already have one?

You can use git blame to see the reason why we are doing memfd reopen fce196d

But in case of memfd_secret AFAIU, we can't read opened file descriptor from another process context, so it means that there is no issue and no need to reopen an FD, right?

warusadura · 2023-06-13T14:31:50Z

No, I did not :D I'm guessing it comes from here. I tried to figure this out with gdb but, it can't recognize list argument/symbol.

I strongly recommend you to pay some time to understand how this machinery works.
Forget about gdb. You don't need gdb here :-)
Btw, compiler macros are compile-time thing, not runtime, so gdb is not your friend here.
