[PATCH 0/2] MR4008: secur32: Fix schannel handles.

[Paul Gofman (＠gofman)]

Access to handle table is actually concurrent (and races / corrupts memory / crashes in practice when apps use different security contexts from different threads).

Then, unrelated to races, schan_handle_table can be reallocated and then schan_free_handles chain points to old memory location. Alternatively to patch 2, that could be fixed up on reallocating schan_handle_table, but it seems to me we can as well just scan the handle table for free slots.
