4 12:24:47 2020 -0700 # # Merge tag 'keys-fixes-20200329' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs # # Pull keyrings fixes from David Howells: # "Here's a couple of patches that fix a circular dependency between # holding key->sem and mm->mmap_sem when reading data from a key. # # One potential issue is that a filesystem looking to use a key inside, # say, ->readpages() could deadlock if the key being read is the key # that's required and the buffer the key is being read into is on a page # that needs to be fetched. # # The case actually detected is a bit more involved - with a filesystem # calling request_key() and locking the target keyring for write - which # could be being read" # # * tag 'keys-fixes-20200329' of
