tests: add close_range() tests This adds basic tests for the new close_range() syscall. - test that no invalid flags can be passed - test that a range of file descriptors is correctly closed - test that a range of file descriptors is correctly closed if there there are already closed file descriptors in the range - test that max_fd is correctly capped to the current fdtable maximum Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Jann Horn <jannh@google.com> Cc: David Howells <dhowells@redhat.com> Cc: Dmitry V.

selftests: core: Fix incorrect kernel headers search path Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents building against kernel headers from the build environment in scenarios where kernel headers are installed into a specific output directory (O=...).

selftests:core: test coverage for dup_fd() failure handling in unshare_fd() At some point there'd been a dumb braino during the dup_fd() calling conventions change; caught by smatch and immediately fixed. The trouble is, there had been no test coverage for the dup_fd() failure handling - neither in kselftests nor in LTP. Fortunately, it can be triggered on stock kernel - ENOMEM would require fault injection, but EMFILE can be had with sysctl alone (fs.nr_open). Add a test for dup_fd() failure.
