[Fix] Partial backport of dd821e0c95a64b5923a0c57f07d3f7563553e756 ("io_uring: fix missing msg_name assignment"). The recvmsg side does not seed to set msg_name, as it copies from a local/stack kernel address (at ____sys_recvmsg) to a uaddr parameter, which is given when doing the copy_msghdr operation. [Test case] LTP io_uring02 was run, and an equivalent recvmsg test was done too. A successfull sendmsg test (without the chroot at io_uring02 test) was also tested. [Potential regressions] io_uring sendmsg/recvmsg paths could fail, potentially leading to a system crash or even a security vulnerability. ----------------------------------------------------------------------- io_uring02 from ubuntu_ltp_syscalls fails on F/oem-5.6 5.6.0-1056.60 on host spitfire This test isn't found to be ran on previous versions on F/oem-5.6, so would not consider this to be a regression. 26934. 05/07 14:42:48 DEBUG| utils:0153| [stdout] tag=io_uring01 stime=1620398217 dur=0 exit=exited stat=0 core=no cu=0 cs=0 26935. 05/07 14:42:48 DEBUG| utils:0153| [stdout] startup='Fri May 7 14:36:57 2021' 26936. 05/07 14:42:48 DEBUG| utils:0153| [stdout] tst_test.c:1311: TINFO: Timeout per run is 0h 05m 00s 26937. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Test timeouted, sending SIGKILL! 26938. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Test timeouted, sending SIGKILL! 26939. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Test timeouted, sending SIGKILL! 26940. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Test timeouted, sending SIGKILL! 26941. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Test timeouted, sending SIGKILL! 26942. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Test timeouted, sending SIGKILL! 26943. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Test timeouted, sending SIGKILL! 26944. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Test timeouted, sending SIGKILL! 26945. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Test timeouted, sending SIGKILL! 26946. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Test timeouted, sending SIGKILL! 26947. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Test timeouted, sending SIGKILL! 26948. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Cannot kill test processes! 26949. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Congratulation, likely test hit a kernel bug. 26950. 05/07 14:42:48 DEBUG| utils:0153| [stdout] Exitting uncleanly... 26951. 05/07 14:42:48 DEBUG| utils:0153| [stdout] tag=io_uring02 stime=1620398217 dur=350 exit=exited stat=1 core=no cu=0 cs=0
