Subject: [LTP] [PATCH] syscalls/shmctl05: new test for IPC file use-after-free bug
Date: Wed, 27 Jun 2018 15:59:03 +0200	[thread overview]
Message-ID: <20180627135903.GB32300@rei> (raw)

Hi!
Looks like if we drop the callibration from the test and use the fuzzy
sync library only as a spinlocks to synchronize the IPC_RMID against the
remap_file_pages the bug gets triggered very reliably for me.
