tolomae opened a new issue, #19849:
URL: https://github.com/apache/nuttx/issues/19849
### Description / Steps to reproduce the issue
# Summary
We believe to have found a use-after-free race condition between
tcp_timer_expiry() and tcp_stop_timer() in net/tcp/tcp_timer.c. Under network
disruption (peer resets, cable pulls, rapid reconnects), it can either crash
the board or leave the TCP/IP stack permanently deadlocked while the rest of
the system keeps running.
# Environment
- Board: custom hardware, ESP32-P4, silicon revision 1.3
- Build: single-core NuttX (CONFIG_SMP not set)
- Network: Ethernet via the ESP32-P4 EMAC driver (CONFIG_ESPRESSIF_EMAC=y)
- NuttX version: 13.0.0 commit 8b49e46b9e (nuttx-8.2-26649-g8b49e46b9e)
- Relevant config: CONFIG_NET_TCP=y, default work queue setup (LPWORK)
# Symptoms
We have an app that periodically sends and receives data on a TCP/IP client
socket. When the connection gets stale, the app automatically tries to
establish a new connection to the host. When this connection gets repeatedly
disrupted (by stopping the server, pulling the network cable, or killing the
TCP connection), we observed either
1) the board crashing alltogether
2) the firmware running, but with all network access stopped (no ping, no
tcp client / servers working anymore)
When in state (2), a call to any IP related app (like ifconfig, ping etc.)
would then result in the firmware hanging completly.
# What we found
We caught the crash live under JTAG by breaking on riscv_exception. Three
separate captures all showed the identical signature:
```
mcause = 5 (Load Access Fault)
mtval = 0x24
a0 = 0x14
```
a0 (the argument to the faulting call) turned out to match `offsetof(struct
net_driver_s, d_lock)` exactly:
```
(gdb) print &((struct net_driver_s *)0)->d_lock
$1 = (rmutex_t *) 0x14
```
And disassembly of the faulting functions entry
(`nxrmutex_unlock`/`nxsem_trywait`, depending on capture) confirmed it
dereferences `a0 + 0x10` on its first instruction, where `0x14 + 0x10 = 0x24`,
matches `mtval`. So it seemed like every crash was some lock-handling call made
with a device pointer of exactly `NULL`.
Searching the network stack for callers that pass a device pointer into a
lock/unlock call without a NULL check turned up only `tcp_timer_expiry()` in
`tcp_timer.c`, which reads `conn->dev` three separate times with no guard at
all:
```
netdev_lock(conn->dev);
netdev_txnotify_dev(conn->dev, TCP_POLL);
netdev_unlock(conn->dev);
```
It's queued via `work_queue(LPWORK, &conn->work, tcp_timer_expiry, ...)`,
and each of our captures had work_thread/lpwork on the stack.
Looking for how the pointer was cleared to NULL, what we think is happening
is the following: after the socket is closed using `tcp_free()`, the whole
struct is cleared in `net_bufpool_free`:
```
memset(net_bufnode, 0, pool->nodesize); /* zeroes the whole struct,
including dev */
```
Though `tcp_free()` also tries to stop the timer using `tcp_stop_timer`,
this function internally uses the async `work_cancel()`. We believe the async
cancel only cancels the timer if it has not yet fired, which leaves a window
where `tcp_timer_expiry` might run with a zeroed out structure.
# Conclusion
While the above is just our best guess on how the crashes came to be, we
tried replacing `work_cancel` with `work_cancel_sync` and have since not seen
any crashes.
The crashes are somewhat reproducible, though it typically takes 10-15
minutes of disrupting the TCP connection. So should there be any useful things
to check with GDB, we'll be happy to do so.
