Details

In the Linux kernel, the following vulnerability has been resolved:

net/handshake: Fix handshakereqdestroy_test1

Recently, handshakereqdestroy_test1 started failing:

Expected handshakereqdestroytest == req, but handshakereqdestroytest == 0000000000000000 req == 0000000060f99b40 not ok 11 req_destroy works

This is because "sockrelease(sock)" was replaced with "fput(filp)" to address a memory leak. Note that sockrelease() is synchronous but fput() usually delays the final close and clean-up.

The delay is not consequential in the other cases that were changed but handshakereqdestroytest1 is testing that handshakereqcancel() followed by closing the file actually does call the ->hpdestroy method. Thus the PTR_EQ test at the end has to be sure that the final close is complete before it checks the pointer.

We cannot use a completion here because if ->hp_destroy is never called (ie, there is an API bug) then the test will hang.
