Hi Linux kernel maintainers,
We found and validated an issue triggered through
net/netfilter/ipvs/ip_vs_ftp.c. An unprivileged user can trigger it by
creating a user namespace and a network namespace. We tested the fix with
the same trigger. The change applies to the generic
ip_vs_conn_expire() control-chain cleanup path. For the reported trigger,
it only defers recursive controller expiration; testing showed no change to
other IPVS behavior.
We will provide detailed information about the bug
in this email, along with a PoC to trigger it.
---- details below ----
Bug details:
The trigger entry point is ip_vs_ftp_out() in
net/netfilter/ipvs/ip_vs_ftp.c. It parses an EPSV reply and creates a
wildcard data connection using the advertised port. If that port is 21,
ip_vs_conn_new() binds the new connection to the FTP helper a second time,
because 21 is the helper's control port. The connection has
IP_VS_CONN_F_NO_CPORT, so the next connection from the same client to the
VIP on port 21 matches the wildcard entry instead of creating a new
top-level entry. Repeating EPSV builds a chain of controlled connections.
The root cause is recursive cleanup in ip_vs_conn_expire(), implemented in
net/netfilter/ipvs/ip_vs_conn.c. During network namespace teardown,
cleanup_net invokes the IPVS connection cleanup path. When a leaf expires,
ip_vs_conn_expire() can synchronously expire its controller through
ip_vs_conn_del_put(). A long chain therefore causes recursive calls to
ip_vs_conn_expire() and exhausts the kernel stack.
The fix removes the old ip_vs_conn_del_put() helper. It sets the
controller's timeout to zero, expedites its pending timer with
ip_vs_conn_expire_now(), and drops the temporary reference. The timer
callback then cleans up one controller at a time instead of recursing
through the chain.
The trigger was run as an unprivileged user with:
SELF_UNSHARE=1 MODE=exit ./poc.sh 200
The script runs unshare -Urn, configures loopback, and installs the IPVS
service through the legacy sockopt ABI. It then repeats the EPSV exchange.
The unpatched run printed "built 200 connections" before the namespace
exited. The kernel then produced the decoded KASAN report below. The fixed
run produced the same output and returned 0; its serial log had no BUG,
KASAN report, kernel panic, or stack-guard report.
The test ran in an x86 QEMU VM with 2 vCPUs and 2 GB of RAM.
Reproducer:
SELF_UNSHARE=1 MODE=exit ./poc.sh 200
The PoC is a shell/Python script; no compilation is required.
We did not use packetdrill because this bug requires more than a packet
sequence. The PoC must create and destroy user and network namespaces,
configure an IPVS service through the legacy sockopt ABI, and run a
cooperating backend FTP server. A packetdrill script cannot express
the required namespace setup and teardown. The shell/Python PoC therefore
drives the full trigger.

When a controlled IPVS connection expires, its controller may be expired
synchronously if it has no remaining controlled connections. A chain of
controlled connections can then cause recursive calls to
ip_vs_conn_expire() and exhaust the kernel stack during namespace cleanup.
Defer controller expiration to its timer instead of expiring it
synchronously. Set its timeout to zero, expedite its pending timer with
ip_vs_conn_expire_now(), and drop the temporary reference. This preserves
the existing cleanup semantics while limiting cleanup to one controller per
timer callback.
Fixes: f9200a52eedf ("ipvs: avoid expiring many connections from timer")

Hm, may be we should also avoid such long chains.
Probably in separate patch, for example:

The only problem I see with your proposed change is
that we may need 2-3 timer ticks to expire a DATA->CTL->TPL
chain. Or it expires on the same tick?
Alternative would be to jump to the beginnig of the
function after successful timer_delete() for our cp->control,
i.e. to use loop instead of recursion. I.e. ip_vs_conn_del_put()
can be converted to function that returns bool instead of
calling ip_vs_conn_expire(), so that we can know if to loop.
If ip_vs_conn_flush() demands faster expiring, a
loop will work faster. What do you think?
Regards

Hello Julian,
Thanks for reviewing this and for suggesting the FTP helper change.
I agree that a loop is preferable, especially if ip_vs_conn_flush() needs to
expire the controller chain promptly. The follow-up is split into two
separate patches.
The first patch changes ip_vs_conn_del_put() to report whether it successfully
deleted the controller's timer. ip_vs_conn_expire() then follows the
controller through a repeat path instead of recursively invoking itself. This
keeps cleanup synchronous, avoids recursive stack growth, and does not wait
for additional timer ticks.
The second patch is a separate FTP helper fix that prevents the helper from
creating unnecessarily long controller chains. ip_vs_ftp_out() rejects a
zero port and configured control ports in the passive-data path, covering
both PASV and EPSV. ip_vs_ftp_in() also rejects a zero client port in active
mode.
Best regards,
Zihan Xi
