In this document, we propose to develop a crate named page-cache that implements page caches, a common OS mechanism that is key to the I/O performance of file systems.

Overview

Design goals

The crate is intended to provide the ability to retrieve, insert, update,and evict cached pages so file system developers can utilize it to accelerate block I/O. To do so, a file system should perform all I/O through the page cache. For a write, data are first written to the page cache, and later flush the dirty pages in the page cache to the disk. For a read, an attempt to retrieve the data from the page cache should be made first. If the attempt fails, then the file system should load the data from the disk and insert a new entry to the page cache. This is known as the write-back cache policy.

The page cache mechanism allows multiple file system users. Each mounted file system can create and manage its own instance of page cache. A group of page caches owned by different file systems can share a common pool of memory pages.

The page cache is designed to achieve the following desirable properties.

• Concurrency. The page cache needs to synchronize the concurrent access from multiple readers, writers, or flushers to the same pages.
• I/O free. The page cache should focus on managing cached pages, not performing I/O. It should be decoupled from the rest of the I/O stack, including file systems and block devices.
• Memory safety. The users should be able to use the page caches with unsafe code as well as possible.

Differences from Linux

The proposed design differs greatly from the one in Linux for two reasons.

• Written in Rust, this crate embraces some of the best practices in software engineering---like memory safety, abstraction, and modularity---that are valued more by the Rust community than the Linux kernel community.
• This crate is intended for use in Occlum, which do not demand a page cache mechanism that is as general as the one in Linux. In particular, Linux's current page cache is a unification of the page cache (for file I/O) and the buffer cache (for block I/O) in Linux's early implementation. This crate is more like Linux's buffer cache.

API

The crate provides the public traits below.

• GlobalAllocExt is a trait for global memory allocators that can monitor its free memory.
• PageCacheFlusher allows the owner (most likely a file system) of a page cache to specify user-specific I/O logic to flush the dirty pages of a page
  cache.

as well as the public types below:

• PageCache<A: GlobalAllocExt> manages the cached pages for a domain of key (e.g., block IDs).
• Page<A: GlobalAllocExt> is a 4KB-sized block of memory obtained from an allocator.
• PageHandle<A: GlobalAllocExt> is the handle to a cached page acquired from a page cache.
• PageState tells the state of a cached page.

Architecture

The internal types:

• PageEvictor<A: GlobalAllocExt> spawns a task to flush and evict pages of all instances of PageCache<A> when the memory of A is low.

Example: CachedDisk

To showcase the usage of this crate, we implement CachedDisk, which uses PageCache to accelerate the access to a backing block device.

use core::sync::atomic::{AtomicBool, Ordering};
use core::sync::Arc;

use async_io::event::{Events, Poller};
use async_rt::mutex::RwLock as AsyncRwLock;
use async_rt::wait::{Waiter, WaiterQueue};
use block_device::{BlockDevice, BlockId, BLOCK_SIZE};
use page_cache::{GlobalAllocExt, Page, PageCache, PageCacheFlusher, PageHandle, PageState};

/// A virtual disk with a backing disk and a page cache.
///
/// Thanks to the page cache, accessing a disk through
/// `CachedDisk` is expected to be faster than
/// accessing the disk directly.
///
/// `CachedDisk` exhibits the write-back strategy: writes
/// are first cached in memory, and later flushed to the
/// backing disk. The flush is either triggered by an
/// explicit flush operation or performed by a background
/// flusher task.
///
/// The memory allocator for the page cache is specified
/// by the generic parameter `A` of `CachedDisk<A>`.
pub struct CachedDisk<A>(Arc<Inner<A>>);

    cache: PageCache<BlockId, A>,
    flusher_wq: WaiterQueue,
    // This read-write lock is used to control the concurrent
    // writers and flushers. A writer acquires the read lock,
    // permitting multiple writers, but no flusher. A flusher
    // acquires the write lock to forbid any other flushers
    // and writers. This policy is important to implement
    // the semantic of the flush operation correctly.

Reference implementation

Given the complexity of the page cache mechanism, a design can hardly be justified until a non-trivial amount of code is written. In this spirit, we provide a high-fidelity Rust code to show what the crate looks like. But be aware: it is by no means complete or correct, even in grammar. It is just a good starting point. Also, there is also a per-file page cache that is complement to this reference implementation.

The SyncIoDisk in sgx-disk is not scalable on concurrency.

The problem is that there is a lock hold while doing I/O. This lock can be removed if using read_at and write_at API.

• Modify the UnionFS
  We can modify the unionfs to accept async-sfs as the RW layer and the integrity-protected SEFS as the RO layer. By doing this, we can take the advantage of sefs-cli tool and the read-performance of SEFS. Thanks to the write-performance of async-sfs, the I/O throughout will meet our expectations.

• Improve functionality of Async-SFS
  Currently, the max file size is 4GB and the max fs size is 16TB in async-sfs , which is at the same level as EXT2. We should support bigger file size and bigger fs size to be equal to EXT4. The max file size is 16TB and the max fs size is 1EB in EXT4.

• Improve the Usability
  The total size of async-sfs should be configured in Occlum.json(or Occlum.yaml in the future), which is a bother for users.
  Can we just calculate the size according to the remaining disk size of Host OS? If the configuration is too big, just return an error to tell the users.
  The page cache size should be configurable for users, and the kernel_space_heap_size can be expanded from the page cache size automatically.

• Improve the Stability
  Test the stability of Async-SFS + SwornDisk for all the demos

• (Optional)Remove the as_sync_inode workaround used in vm
  If the executable binary may be stored in async-sfs, the vm subsystem should load it from async Inode instead of sync Inode. So the workaround should be fixed.

• Feature Name: untrusted device memory
• Start Date: 2022-08-22

Summary

Occlum gets the untrusted memory range and registers the untrusted memory range into the SGX untrusted allocator.

Motivation

When supporting the untrusted device, we could get some untrusted memory that is shared with the device. The SGX untrusted allocator could help to manage this area. The application may do mprotect or munmap with the virtual address inside the untrusted area.

Guide-level explanation

The existing sgx-untrusted-alloc crate (https://github.com/occlum/ngo/tree/master/src/libos/crates/sgx-untrusted-alloc) could be extended to support the new feature.

The new interfaces are required:

1. insert a committed untrusted memory range into the allocator
2. remove a range of memory from the allocator (If the range is added by the insert interface)

Below is one example:
When an application performs munmap with an untrusted memory address

1. First, check whether the address is inside the enclave or an outside address.
2. If the address is an outside address, query the Untrusted Allocator to confirm it is a legal address managed by the allocator
3. Perform the munmap with the address
4. If the area is mapped with an untrusted device, remove the range from the allocator

Describe the bug

pthread case hangs when running glibc test in simulation mode. It is not always happening but can still be easily reproduced if running for within 10 times.

To reproduce

Steps to reproduce the behavior:

1. Install NGO master (a999922) in release mode
2. TESTS=pthread OCCLUM_LOG_LEVEL=trace TEST_CPUS=2 SGX_MODE=SIM taskset -c 0-1 make test-glibc times=100

Expected behavior

All tests can pass.

Environment

• HW: [e.g. SGX1, SGX2] SGX2
• OS: [e.g. Ubuntu18.04, CentOS8.1] ubuntu 18.04
• Occlum version: [e.g. 0.17.0] NGO master (a999922) release mode

Additional context

Running pthread musl test with all other variables the same can't reproduce this behavior in 100 times.
Running pthread glibc test in hardware mode with all other variables the same can't reproduce this behavior in 100 times.
Not sure if this is related to libc or SGX mode.

Background

The async_io::event::Pollee maintains a state of Events that can be polled by poller. Currently, there are three methods that can change the Events state:

• add_events: Add some new events, triggering interesting pollers.
• del_events: Delete some events.
• reset_events: Clear all events.

Problem

The individual methods are thread safe. But sometime the user code may want to use them in combination.

pollee.reset_events();
pollee.add_events(Events::OUT);

The problem with this code is that since the two operations as a whole are not atomic, other concurrent threads may observe an intermediate states (no events). This could cause problems in some use cases. The user code may use an auxiliary mutex to ensure the atomicity, but this is fragile.

Solution

I propose two actions. First, review the current usage of Pollee and confirm the atomicity issue. Second, replace the three methods with the following two new methods.

• set_events(new: Events, will_notify: bool), which sets a pollee's state to a new state atomically. If will_notify is true, then interesting pollers will be notified.
• update_events(to_del: Events, to_add: Events), which removes some events from a pollee's state and add some new ones to it atomically. The interesting pollers will be notified about the new events.

Their semantics are shown below.

• set_events(new) = reset_events() + add_events(new)
• update_events(to_del, to_add) = del_events(to_del) + add_events(to_add)

The old three methods can be readily implemented with the new ones.

• add_events(to_add) = update_events(Events::empty(), to_add)
• del_events(to_del) = update_events(to_del, Events::empty())
• reset_events() = set_events(Events::empty())

As you can see, the two new methods are more powerful.

When doing stress test, e.g., TESTS=server STRESS_TEST_TIMES=500 make test, the test might failed after hundreds of tests.
The error is bind failed (address in use), which is because of the old socket that listening in the port isn't closed.
To close a listening socket, we first cancel all ongoing accept io-uring request, however, the request seems lost when doing stress test. e.g., we try to cancel 10 requests, but only 9 requests were canceled, which left one request to lose.

When I add log to locate this bug, I find it's hard to reproduce the bug if I add many logs in io-uring operation.

I thought it's might because of the third crate io-uring crate, since our io-uring crate is outdated.

And I try to update the io-uring crate (The interface of io-uring crate changed a lot), and then I meet more bugs...... (The code is in https://github.com/ShuochengWang/io-uring/tree/sgx and https://github.com/ShuochengWang/ngo/tree/dev-network9)

Describe the bug

Any inodes in Linux has typically these three timestamps:

• atime: The time of last access of file data
• mtime: Time of last modification of file data
• ctime: The time of last status change of file status

(See more details at https://man7.org/linux/man-pages/man7/inode.7.html)

We can get such attributes from stat()(https://man7.org/linux/man-pages/man2/lstat.2.html).

I discover that in occlum and ngo, the atime, mtime and ctime remain unchanged when we read/write content from a file descriptor, or change its attributes (such as chmod, chown ...). Such behavior is different from Linux.

To reproduce

Here is the sample program:

// First we need to create a file at 'file_path' which has O_RDWR permission
static int test(const char *file_path) {
    int ret, fd;
    struct stat stat_buf;
    char c;
    const char *content = "abcde";

    fd = open(file_path, O_RDWR);
    ret = write(fd, content, strlen(content));
    if (ret != strlen(content))
        THROW_ERROR("cannot write, ret=%d\n", ret);

    ret = stat(file_path, &stat_buf);
    printf("atime: { %ld, %ld }, mtime { %ld, %ld }\n",
            stat_buf.st_atim.tv_sec, stat_buf.st_atim.tv_nsec,
            stat_buf.st_mtim.tv_sec, stat_buf.st_mtim.tv_nsec);
    nanosleep(&period_of_100ms, NULL);

    printf("just open: \n");
    fd = open(file_path, 0);
    close(fd);
    ret = stat(file_path, &stat_buf);

Expected behavior:

The atime is updated after we read from the file (See Open and read:)
The mtime and ctime are updated after we write to the file (See Open and write:)
The ctime is updated after we modify atime and mtime by invoking utimes (See change ctime:)

The atime remains unchanged after we read from the file (See Open and read:)
The mtime and ctime remain unchanged after we write to the file (See Open and write:)
The ctime remains unchanged after we modify atime and mtime by invoking utimes (See change ctime:)

Environment

Additional context

None

Possible solution/Implementation

None

Bug:

1. first add one file with fd x to epoll interest
2. close this file
3. create a new file, which will reuse the fd x since FileTable will reuse fd
4. add the new file to epoll interest
5. epoll will report EEXIST error!

Might Related Todos:

• // TODO: add fd to FileHandle?
• // TODO: make FileTable a struct of internal mutability to avoid deadlock.
• // TODO: close host_fd

Solutions:

1. generate different fd in FileTable
2. Find a better design for: do_close, drop, observer, the close of socket file (which is Arc<...>)

Describe the bug

The ioctl unit test would crash the system if the system does not support DCAP.

Environment

• HW: SGX2 [e.g. SGX1, SGX2]
• OS: [e.g. Ubuntu18.04, CentOS8.1]
• Occlum version: [e.g. 0.17.0]

The arc_new_cyclic feature has been stablized in Rust. 1.58. Since we are using recently new nightly version, I think we should already have this feature.

This enables creating self-referencing Arc object.

use std::sync::{Arc, Weak};

struct Foo {
    me: Weak<Foo>,
}

impl Foo {
    /// Construct a reference counted Foo.
    fn new() -> Arc<Self> {
        Arc::new_cyclic(|me| Foo {
            me: me.clone(),
        })
    }

    /// Return a reference counted pointer to Self.
    fn me(&self) -> Arc<Self> {
        self.me.upgrade()
    }
}

Since this pattern is so common, NGO even adds a dedicated crate, new-self-ref-arc for exactly this purpose. We should remove the crate and use new_cyclic instead.

Anyone interested in taking this refactoring task?

When doing stress test, e.g., TESTS=server STRESS_TEST_TIMES=500 make test, the test might failed after hundreds of tests.
The error is bind failed (address in use), which is because of the old socket that listening in the port isn't closed.
To close a listening socket, we first cancel all ongoing accept io-uring request, however, the request seems lost when doing stress test. e.g., we try to cancel 10 requests, but only 9 requests were canceled, which left one request to lose.

When I add log to locate this bug, I find it's hard to reproduce the bug if I add many logs in io-uring operation.

I thought it's might because of the third crate io-uring crate, since our io-uring crate is outdated.

And I try to update the io-uring crate (The interface of io-uring crate changed a lot), and then I meet more bugs...... (The code is in https://github.com/ShuochengWang/io-uring/tree/sgx and https://github.com/ShuochengWang/ngo/tree/dev-network9)

[2021-10-20T05:37:54.697Z][ WARN] HostFS: sync is unimplemented

Now we use start_enter_syscall_thread to walkaround the limition of io-uring, see details in axboe/liburing#273

    pub unsafe fn start_enter_syscall_thread(fd: c_int) {
        use std::thread;
        println!("start_enter_syscall_thread");
        thread::spawn(move || loop {
            syscall(
                __NR_io_uring_enter as c_long,
                fd as c_long,
                1,
                0,
                0,
                std::ptr::null() as *const c_void,
                0,
            );
        });
    }

And the arguments of __NR_io_uring_enter is:
io_uring_enter(fd, to_submit, min_complete, flags, sig, siglen)

• We should use io-uring kernel polling instead of start_enter_syscall_thread in 5.11+ kernel version
• We should set the min_complete to 1 in start_enter_syscall_thread to save power (not tested yet)

Describe the bug

Poll stdin (FD 0) always return readable (Events::IN) even if no input at all.

To reproduce

Steps to reproduce the behavior:

`
/* Watch stdin (fd 0) to see when it has input. */
FD_ZERO(&rfds);
FD_SET(0, &rfds);

/* Wait up to five seconds. */
tv.tv_sec = 5;
tv.tv_usec = 0;

retval = select(1, &rfds, NULL, NULL, &tv);
`
Above code always return immediately.

Expected behavior

No IN event if there is no input.

Environment

• HW: [e.g. SGX1, SGX2]
• OS: [e.g. Ubuntu18.04, CentOS8.1]
• Occlum version: [e.g. 0.17.0]

The feature “sgx” and "auto_run" should be conflict features.

If Occlum links async-file with sgx feature, it will crash at thread '<unnamed>' panicked at 'The sgx thread policy must be Bound!', /root/testtt/deps/rust-sgx-sdk/sgx_tstd/src/thread/mod.rs:92:13

Describe the bug

To test NGO network performance, run iperf server-side on host Linux, and run client inside NGO. And the client-side never exits. From the log, I can see the client hanging at a Recvfrom syscall.

With the same usage, running in Occlum can pass.

To reproduce

Steps to reproduce the behavior:

1. Run iperf server on host: ./iperf -s -p 6888
2. Run iperf client in Occlum: occlum run /bin/iperf -c 127.0.0.1 -p 6888 -P 1 -t 1

Expected behavior

The client-side should exit when the test ends.

Logs

Server-side (strace):
After the test ended, the server close the socket (fd = 4) and exit the thread. However, the client-side didn't respond to the socket close and kept waiting.

Client-side:

So when a side is close, on the other side of the stream, Recvfrom should return 0. From the man page of recv, it also states that:

When a stream socket peer has performed an orderly shutdown, the return value will be 0 (the traditional "end-of-file" return).

But in NGO, it shows a different phenomenon that the close didn't make the recvfrom return. I did a little digging, and it looks like the recvfrom request is submitted to the kernel but it never returns and the calling thread keeps waiting. Thus, it seems like a fault of io_uring that close/shutdown can't cancel pending requests and make them return.

From an issue in liburing (axboe/liburing#568), it looks like it won't be supported before 5.19.

Possible solution/Implementation

Besides this problem, iperf also uses a Netlink socket for other usages in this test. NGO is also not supported. To run this tool, there are mainly two solutions:
(1) Wait for the kernel 5.19 and hopefully, this usage is supported, and update all related libraries to use this feature. Also, add support for Netlink socket type.

(2) Add an ocall based implementation as a fallback solution when running applications like this. We could encourage the users to try io_uring based network first and if it can't use, use this fallback solution. At least, the in-enclave scheduling can bring some benefits. The drawback of this solution is that some of the network ocall will be blocking and can't release the CPU.

The Problem

NGO uses Rust async / await to reconstruct the code and realize asynchronous. Because Rust async / await needs to be executed through Rust async runtime, NGO has implemented a basic version of Rust async runtime, namely async-rt.

With async-rt, NGO implements M : N : P in-enclave scheduling. Specifically, there are M user threads, N LibOS coroutines, and P host threads. The executor of Rust async runtime runs on P host threads (that is, P Linux threads). The executor schedules N LibOS coroutines (that is, N Rust async tasks). N LibOS coroutines contain M user threads and N - M LibOS system tasks.

However, there is no scheduler for async-rt at present. The executor of async-rt can only run tasks in its local queue. This will lead to the following problems for NGO:

1. Unbalanced load: some host threads are busy, while others are idle. This may result in increased program latency.
2. Waste of computing power: if the host thread is idle, it will continuously poll the local queue, which will waste CPU computing power.
3. No priority: in NGO, some tasks have lower priority, such as some LibOS background tasks, but async-rt can't distinguish priorities at present.

In addition, in async-rt, if the task is in the pending state, the corresponding waker will be set. Invoking waker.wake() will rejoin the task to the local queue. If wake() is invoked repeatedly (It is feasible at the API level), the queue will contain multiple identical tasks, which will affect performance and scheduling.

Design Goals

Add scheduler to the Rust async runtime async-rt and make async-rt a production-level Rust async runtime with no_std.
The scheduler should meet the following requirements:

• load balancing
• save computing power
• support priority
• avoid repetitive tasks

The priorities of these requirements decrease in turn. We will implement these requirements in order of priority.

• Feature Name: mem_cleaning_thread
• Start Date: 2022.2.10

Summary

Use a number of kernel threads to clean munmap-ed pages in an asynchronous way.

Motivation

Due to the lack of the page table, for applications running inside Occlum, when the user mmap a range of memory, the pages corresponding to the memory are actually committed and require clean-up even if the user never uses the memory.
For some applications, it will try to mmap a big range of memory, do nothing on it and just unmap the memory. In this case, the clean-up process will consume a lot of time and can potentially cause the application to misbehave.
This design is trying to reduce the time of munmap to minimize this gap.

Guide-level explanation

This feature is transparent to end-users.

Reference-level explanation

1. Define the clean request.
   We use a clean request to define the cleaning process of a range. A clean request can be generated when munmap a range. And then the request is responded by the clean worker to do the actual cleaning (i.e. set 0). And when the cleaning is done, the clean worker will put the range back to the free space manager for further allocation.

2. Define the structure to handle the clean request
   There could be multiple threads from multiple processes munmap-ing different ranges. And there can be at most half of the vCPU number of threads doing the cleaning. Thus, I choose to use MPMC queue provided by flume.

3. Define the rule for the clean request

• If clean request < CLEANING_TASK_THREASHOLD, clean by the requesting thread itself.
  Only if the clean request is greater than CLEANING_TASK_THREASHOLD, use clean thread to do the cleaning. Otherwise, the current thread must do it on its own. Because cleaning small range is fast, and sending to other threads will introduce more overhead to the entire system.
• If CLEANING_TASK_THREASHOLD < request < REQ_MAX_SIZE, the clean thread will do the cleaning as a single request (use one single thread to do the cleaning)
• If REQ_MAX_SIZE < request, split the request into multiple small requests of REQ_MAX_SIZE and make several cleaning threads to do the cleaning
• If there are too many clean requests in the queue which exceeds the high watermark, don't send clean requests. Clean by the requesting thread itself.

4. Define the behavior of the clean threads
   At the init stage, create half of the vCPU number of threads. And if a worker thread can't receive requests, it will wait. Once a request is sent by requesting thread, it will also wake one worker.
   The clean workers should be run with low priority. If there are many user tasks pending, the clean worker shouldn't clean anymore.

5. What if the free space is not enough
   For mmap, if the desired memory is not available while there are many requests in the queue, the allocation thread should become a worker thread and help respond to the requests in the queue until the queue is empty. And then it will try to allocate again. And if it still fails this time, return with the error number.

Drawbacks

There is one limitation. The mmap syscall is defined like this:

void *mmap(void *addr, size_t length, int prot, int flags,
                  int fd, off_t offset);

When the user calls mmap with specified addr but MAP_FIXED is not set in flags, this means the user assumes addr is a good place and it would be better for the kernel to allocate memory from that address but not forcing the kernel to allocate from that address.

For example, the user just munmap a range, and he could assume this range is now free. Later the user wants to mmap a range and would like to just allocate from that address again.

If no other threads are doing mmap, this operation should always succeed. However, with this feature, even if the user munmap a range, he may not mmap to get the same range later because maybe that range is still being cleaned. This clean time depends on the range of the memory. And when the range is cleaned, then the user will be able to mmap from that address again.

This should be fixed.

UPDATE:
This limitation has been removed by tracking the ranges being cleaned of each worker. And when mmap with address is called, the calling thread will become the help worker to help clean all pending requests. And then, check all the ranges being cleaned by other workers to see if the desired range is overlapped and if so, loop and wait. If not, return and start the allocation.

Alternatives

Instead of MPMC to track dirty ranges, use a btree to track all the dirty ranges in address order. Choose btree because it is provided by rust std and has relatively good performance in inserting, removing and finding. Also, each request will have a status indicating if it is dirty, being cleaned, or already clean.

When munmap a range, make it a clean request and mark the status as dirty, and put it to the btree. Then the clean worker can iterate the btree to find the dirty ranges and do the cleaning. And if there are no dirty ranges, put the range back to the free list and merge to bigger free ranges.

This method can handle the mmap with address better but the overall performance is even poorer than not doing this. The reason could be that the clean worker has to iterate the whole btree every time. When the btree is big, this can be very time-consuming. If a request is cleaned and then just remove from the btree, then the btree needs to be unlocked very often and multiple workers will need to wait for the lock.

The PoC implementation can be found here: https://github.com/jessehui/ngo/tree/dev_cleaning_thread_btree

Future Possibilities

With EDMM and trusted page fault, we can achieve more accurate page cleaning.
All the VMs allocated are set to PROT_NONE but recorded the protection bit by the kernel, and once read/write, a page fault is triggered and we can modify the protection bit in the page fault handler and set it to the recorded protection bit and also set the range/page to dirty.
And when the range is munmap-ed, we only need to clean if the range is set to dirty.

Status

Under review: #212

When doing stress test, e.g., TESTS=server STRESS_TEST_TIMES=500 make test, the test might failed after hundreds of tests.
The error is bind failed (address in use), which is because of the old socket that listening in the port isn't closed.
To close a listening socket, we first cancel all ongoing accept io-uring request, however, the request seems lost when doing stress test. e.g., we try to cancel 10 requests, but only 9 requests were canceled, which left one request to lose.

When I add log to locate this bug, I find it's hard to reproduce the bug if I add many logs in io-uring operation.

I thought it's might because of the third crate io-uring crate, since our io-uring crate is outdated.

And I try to update the io-uring crate (The interface of io-uring crate changed a lot), and then I meet more bugs...... (The code is in https://github.com/ShuochengWang/io-uring/tree/sgx and https://github.com/ShuochengWang/ngo/tree/dev-network9)
