Delete the fcloop remote port and then the target port while an
association is being deleted. The Disconnect Association LS is completed
from a work item that can run after nvmet_fc_unregister_targetport() freed
the pending request, which KASAN reports as a use-after-free in
fcloop_tport_lsrqst_work().

It is the better to note which kernel side fix is related to this test case.
I suggest to note the commit title of the kernel fix here.

  If its git hash could be noted, it would be the best, but the fix is not
  yet applied, so we can not do that yet.


When I tried to run this test case, I often observed the test run hanged.
The hang was observed with v7.3-rc4 kernel. It was observed even with the
v2 fix patch [*]. Do you observe hangs on your test systems?

[*] https://lore.kernel.org/linux-nvme/20260921145651.17131-1-ngocthang2710.1999@gmail.com/

Also, please find my comments in line. Thanks!

Nit: ports is an array, so I suggest to seprarte it from other variables and
declare it as an array:

        local -a ports

common/nvme provides _get_fc_host_port(). Let's use it to avoid the
reference to the global variable.

Is there any reason to variate the sleep time here?

I tried to recreate the KASAN use-after-free using v7.3-rc4 kernel, but I was
not able to do it on my test node. I modified the above line to "sleep 0", then
I was able to recreate the failure. I guess the sleep lengths f
r KASAN recreation could be test system dependent.

Delete the fcloop remote port and then the target port while an
association is being deleted. The Disconnect Association LS is completed
from a work item that can run after nvmet_fc_unregister_targetport() freed
the pending request, which KASAN reports as a use-after-free in
fcloop_tport_lsrqst_work().

Kernel fix: "nvmet-fc: flush nvmet_wq twice on targetport unregister"

Changes in v2 (thanks Shin'ichiro for the review):
- Note the kernel fix's commit title in the file header.
- local -a ports, and use _get_fc_host_port() instead of reading
  ports_to_hosts directly.
- Connect with --ctrl-loss-tmo 0. Without it, the host can spend up to
  NVMF_DEF_CTRL_LOSS_TMO (600s) retrying reconnect after we pull the
  remote port, which is likely the hang you saw; disconnecting it
  cleanly then has to wait on that reconnect state first.
- Drop the swept delay before pulling the ports. I could not tell it
  apart from a fixed "sleep 0" here either (KASAN UAF + list_debug BUG,
  both with and without it), so it wasn't earning its complexity.
- v1: https://lore.kernel.org/linux-block/20260921145659.17151-1-ngocthang2710.1999@gmail.com/

Hi Shin'ichiro,

Thanks for testing and the review, v2 is sent:

  [PATCH blktests v2] nvme/071: add a test for fcloop LS request use-after-free
  Message-ID: <20260923134938.12673-1-ngocthang2710.1999@gmail.com>

- Noted the kernel fix's commit title in the file header, since it's not
  applied yet and has no hash.
- local -a ports, and use _get_fc_host_port() instead of reading
  ports_to_hosts directly.
- On the hang: I couldn't reproduce a real hang, but I think I found the
  cause. _nvme_connect_subsys() doesn't pass --ctrl-loss-tmo, so it
  defaults to NVMF_DEF_CTRL_LOSS_TMO (600s). After we pull the remote
  port the host has nothing to reconnect to, and the following
  _nvme_disconnect_subsys() has to wait on that reconnect state before
  it can remove the controller, up to 10 minutes if it lands there.
  v2 connects with --ctrl-loss-tmo 0 so the host gives up on the first
  failed reconnect instead. Let me know if you still see it hang with
  this.
- On the swept delay: I tried a fixed "sleep 0" here too and got the
  same KASAN UAF + list_debug BUG as with the sweep, so it wasn't
  earning its complexity. Dropped it in v2.

Thanks,
Thang

Nguyen, thanks for the v2 patch. The patch looks good to me.

Said that, I still observe the hang when I run the new test case in my test
environment. I applied the kernel side fix patch [1] on top of v7.3-rc7 kernel.
FYI, here I share the dmesg observed along with the hung [2]. Interestingly,
"KASAN: null-ptr-deref in fcloop_t2h_xmt_ls_rsp" was observed. I think it
indicates that the kernel side fix may not be good enough.
