Date: Thu Dec 21 13:57:31 2023 +0000 # # afs: Fix use-after-free due to get/remove race in volume tree # # When an afs_volume struct is put, its refcount is reduced to 0 before # the cell->volume_lock is taken and the volume removed from the # cell->volumes tree. # # Unfortunately, this means that the lookup code can race and see a volume # with a zero ref in the tree, resulting in a use-after-free: # # refcount_t: addition on 0; use-after-free. #

# Fix this by: # # (1) When putting, use a flag to indicate if the volume has been removed # from the tree and skip the rb_erase if it has. # # (2) When looking up, use a conditional ref increment and if it fails # because the refcount is 0, replace the node in the tree and set the # removal flag. # # Fixes: 20325960f875 ("afs: Reorganise volume and server trees to be rooted on the cell") # Signed-off-by: David Howells <dhowells@redhat.com> #
