# 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 # kmemdup_nul+0x24/0x3c # vfs_parse_fs_string+0x5a/0xa1 # generic_parse_monolithic+0x9d/0xc5 #
