-Subject: [PATCH] CVE-2016-4429: sunrpc: Do not use alloca in clntudp_call [BZ
- #20112]
-
-The call is technically in a loop, and under certain circumstances
-(which are quite difficult to reproduce in a test case), alloca
-can be invoked repeatedly during a single call to clntudp_call.
-As a result, the available stack space can be exhausted (even
-though individual alloca sizes are bounded implicitly by what
-can fit into a UDP packet, as a side effect of the earlier
-successful send operation).
-
-(cherry picked from commit bc779a1a5b3035133024b21e2f339fe4219fb11c)
