Subject: Linux 5.19-rc7 liburing test `poll-mshot-overflow.t` and `read-write.t` fail
Date: Thu, 21 Jul 2022 06:21:24 +0700	[thread overview]
Message-ID: <[email protected]> (raw)

Hello Jens,

Kernel version:

   commit ff6992735ade75aae3e35d16b17da1008d753d28
   Author: Linus Torvalds <[email protected]>
   Date:   Sun Jul 17 13:30:22 2022 -0700

       Linux 5.19-rc7

liburing version:

   commit 4e6eec8bdea906fe5341c97aef96986d605004e9 (HEAD, origin/master, origin/HEAD)
   Author: Dylan Yudaken <[email protected]>
   Date:   Mon Jul 18 06:34:29 2022 -0700

       fix io_uring_recvmsg_cmsg_nexthdr logic
       
       io_uring_recvmsg_cmsg_nexthdr was using the payload to delineate the end
       of the cmsg list, but really it needs to use whatever was returned by the
       kernel.

Two liburing tests fail:

   Tests failed:  <poll-mshot-overflow.t> <read-write.t>
   make[1]: *** [Makefile:237: runtests] Error 1
   make[1]: Leaving directory '/home/ammarfaizi2/app/liburing/test'
   make: *** [Makefile:21: runtests] Error 2


   ammarfaizi2@integral2:~/app/liburing$ uname -a
   Linux integral2 5.19.0-rc7-2022-07-18 #1 SMP PREEMPT_DYNAMIC Mon Jul 18 15:42:27 WIB 2022 x86_64 x86_64 x86_64 GNU/Linux
   ammarfaizi2@integral2:~/app/liburing$ test/read-write.t
   cqe res -22, wanted 8192

   ammarfaizi2@integral2:~/app/liburing$ test/poll-mshot-overflow.t
   signalled no more!
   ammarfaizi2@integral2:~/app/liburing$

JFYI, -22 is -EINVAL.

read-write.t call trace when calling fprintf(..., "cqe res %d, wanted %d\n", ...):

   #0  ___fprintf_chk (./debug/fprintf_chk.c:25)
   #1  fprintf (/usr/include/x86_64-linux-gnu/bits/stdio2.h:105)
   #2  __test_io (read-write.c:181)
   #3  test_buf_select (read-write.c:577)
   #4  main (read-write.c:849)

poll-mshot-overflow.t call trace should be trivial.
