The receive side was left as it was. The two differ for REQ\_OP\_WRITE\_ZEROES, which has no physical segments but a non-zero blk\_rq\_bytes(), so setup leaves req->iter untouched while the receive gate lets a C2HData through and nvme\_tcp\_recv\_data() copies into whatever the previous command on that tag left there. The driver-private area is zeroed only when the tag set is allocated. Reproduced with a test target that leaves a residual iterator on a tag and then sends a C2HData for a WRITE\_ZEROES command on the same tag: BUG: KASAN: wild-memory-access in \_copy\_to\_iter+0x642/0x1330 Write of size 512 at addr ffe728c2175dfa81 by task kworker/0:1H/103 CPU: 0 UID: 0 PID: 103 Comm: kworker/0:1H Not tainted 7.2.0-rc5-NVMETCP-gf5098b6bae76 #1 PREEMPT(lazy) Hardware name: QEMU Ubuntu 24.04 PC v2 (i440FX + PIIX, arch\_caps fix, 1996), BIOS 1.16.3-debian-1.16.3-2 04/01/2014 Workqueue: nvme\_tcp\_wq nvme\_tcp\_io\_work Call Trace: dump\_stack\_lvl+0x53/0x70 kasan\_report+0xce/0x100 ? \_copy\_to\_iter+0x642/0x1330 kasan\_check\_range+0x105/0x1b0 \_\_asan\_memcpy+0x3c/0x60 \_copy\_to\_iter+0x642/0x1330 ? \_\_pfx\_sock\_has\_perm+0x10/0x10 ? worker\_thread+0x45b/0xd10 ? \_\_pfx\_\_copy\_to\_iter+0x10/0x10 ? \_raw\_spin\_lock\_bh+0x83/0xe0 ? \_\_pfx\_\_raw\_spin\_lock\_bh+0x10/0x10 \_\_skb\_datagram\_iter+0xf3/0x820 ? \_\_pfx\_simple\_copy\_to\_iter+0x10/0x10 ? \_\_asan\_memcpy+0x3c/0x60 ? skb\_copy\_bits+0x58d/0x830 skb\_copy\_datagram\_iter+0x37/0x120 nvme\_tcp\_recv\_skb+0xa07/0x4320 ? \_\_pfx\_nvme\_tcp\_recv\_skb+0x10/0x10 \_\_tcp\_read\_sock+0x1ab/0x810 ? \_\_pfx\_nvme\_tcp\_recv\_skb+0x10/0x10 ? \_\_pfx\_lock\_sock\_nested+0x10/0x10 ? \_\_pfx\_\_\_tcp\_read\_sock+0x10/0x10 nvme\_tcp\_try\_recv+0x152/0x1e0 ? \_\_pfx\_nvme\_tcp\_try\_recv+0x10/0x10 ? \_\_pfx\_mutex\_unlock+0x10/0x10 nvme\_tcp\_io\_work+0x1e4/0x6c0 ? \_\_schedule+0x181a/0x49f0 ? \_\_pfx\_nvme\_tcp\_io\_work+0x10/0x10 process\_one\_work+0x633/0x1030 Keep the blk\_rq\_payload\_bytes() test and add req->data\_len to it. The old test is what rejects a C2HData naming a tag that is no longer in flight, because blk\_update\_request() zeroes rq->\_\_data\_len on completion; req->data\_len and req->curr\_bio are driver-private and survive completion, so they cannot stand in for it. Setup initialises the iterator only when both req->curr\_bio and req->data\_len are set, so the gate now tests the same two. ## Status Show unmaintained releases | Package | Ubuntu Release | Status |
