From ff8774b5ce3f6b37e5152d0dc06ae46b7a36d1da Mon Sep 17 00:00:00 2001 From: Paul Buetow Date: Thu, 28 May 2026 10:43:37 +0300 Subject: close_range: honor last bound and CLOSE_RANGE_CLOEXEC flag close_range was captured as a single-fd fd_event carrying only first, so the runtime evicted every tracked fd >= first, ignoring the last upper bound and the flags. Bounded calls wrongly dropped still-open higher fds, and CLOSE_RANGE_CLOEXEC (which keeps fds open) was treated as a full close. Reclassify close_range to the two_fd_event kind, mapping fd_a/fd_b/extra to first/last/flags. The runtime now closes only the inclusive [first, last] range (a negative last from ~0U means unbounded) and skips eviction when CLOSE_RANGE_CLOEXEC is set or the syscall fails.
