+Subject: [PATCH] Allow MAP_NORESERVE in sandbox seccomp filter maps
+
+While debugging Scudo on ChromeOS, we found that the no reserve mode
+immediately crashed `sshd`. We tracked it down to the
+sandbox-seccomp-filter.
+
+Being able to mmap with MAP_NORESERVE is useful (if not necessary) for
+some overcommitting allocators.
+
+During mmap calls, the flag MAP_NORESERVE is used by some allocators
+such as LLVM's Scudo for layout optimisation. This causes the sandbox
+seccomp filter for the client subprocess to die with some Scudo
+configurations.
+
+Upstream patch submission:
+https://lists.mindrot.org/pipermail/openssh-unix-dev/2023-December/041095.html
