Christopher Faulet fa5c812a6b BUG/MINOR: buffers: Fix b_alloc_margin to be "fonctionnaly" thread-safe ... b_alloc_margin is, strickly speeking, thread-safe. It will not crash HAproxy. But its contract is not respected anymore in a multithreaded environment. In this function, we need to be sure to have <margin> buffers available in the pool after the allocation. So to have this guarantee, we must lock the memory pool during all the operation. This also means, we must call internal and lockless memory functions (prefixed with '__'). For the record, this patch fixes a pernicious bug happens after a soft reload where some streams can be blocked infinitly, waiting for a buffer in the buffer_wq list. This happens because, during a soft reload, pool_gc2 is called, making some calls to b_alloc_fast fail. This is specific to threads, no backport is needed.		2017-11-13 11:42:48 +01:00
