Date: Tue Dec 8 23:52:03 2020 +0000 # # afs: Fix memory leak when mounting with multiple source parameters # # There's a memory leak in afs_parse_source() whereby multiple source= # parameters overwrite fc->source in the fs_context struct without freeing # the previously recorded source. # # Fix this by only permitting a single source parameter and rejecting with # an error all subsequent ones. # # This was caught by syzbot with the kernel memory leak detector, showing # something like the following trace: # # unreferenced object 0xffff888114375440 (size 32): # comm "repro", pid 5168, jiffies 4294923723 (age 569.948s) # backtrace: # slab_post_alloc_hook+0x42/0x79 # __kmalloc_track_caller+0x125/0x16a #
