Hi David,

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Several BPF sockmap fixes mostly related to bugs in error path
   handling, that is, a bug in updating the scatterlist length /
   offset accounting, a missing sk_mem_uncharge() in redirect
   error handling, and a bug where the outstanding bytes counter
   sg_size was not zeroed, from John.

2) Fix two memory leaks in the x86-64 BPF JIT, one in an error
   path where we still don't converge after image was allocated
   and another one where BPF calls are used and JIT passes don't
   converge, from Daniel.

3) Minor fix in BPF selftests where in test_stacktrace_build_id()
   we drop useless args in urandom_read and we need to add a missing
   newline in a CHECK() error message, from Song.
