| * Add a variant of the Seccomp filter file that allows 'execve'.Philipp Stephani2021-04-112-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is useful when starting Emacs with a Seccomp filter enabled, e.g. using 'bwrap'. * lib-src/seccomp-filter.c (main): Generate new Seccomp files. * lib-src/Makefile.in (all) (seccomp-filter.bpf seccomp-filter.pfc seccomp-filter-exec.bpf seccomp-filter-exec.pfc): Generate new Seccomp files. * .gitignore: Ignore new Seccomp files. * test/src/emacs-tests.el (emacs-tests/bwrap/allows-stdout): New unit test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The binary uses the 'seccomp' helper library. The library isn't needed to load the generated Secure Computing filter. * configure.ac: Check for 'seccomp' header and library. * lib-src/seccomp-filter.c: New helper binary to generate a generic Secure Computing filter for GNU/Linux. * lib-src/Makefile.in (DONT_INSTALL): Add 'seccomp-filter' helper binary if possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When passing this option on GNU/Linux, Emacs installs a Secure Computing kernel system call filter. See Bug#45198. * configure.ac: Check for seccomp header. * src/emacs.c (usage_message): Document --seccomp option. (emacs_seccomp): New wrapper for 'seccomp' syscall. (load_seccomp, maybe_load_seccomp): New helper functions. (main): Potentially load seccomp filters during startup. (standard_args): Add --seccomp option. * lisp/startup.el (command-line): Detect and ignore --seccomp option. * test/src/emacs-tests.el (emacs-tests/seccomp/absent-file) (emacs-tests/seccomp/empty-file) (emacs-tests/seccomp/file-too-large) (emacs-tests/seccomp/invalid-file-size): New unit tests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The primary idea is to allow `kill-buffer' and `kill-emacs' to complete even if Emacs has trouble unlocking the buffer's file. * lisp/userlock.el (userlock--handle-unlock-error): New function, call `display-error'. * src/filelock.c (unlock_file_body): New function, do what 'unlock_file' used to.

| | | | | | | | | | | | | | | | Breaking this is a likely way to break this test, so this saves a bit of time in debugging. * test/src/data-tests.el (data-tests--let-buffer-local): Add assertion to test.
| * Add a test for let-binding unwindingSpencer Baugh2021-03-251-0/+22
| | | | | | | | | | | | | | | | | | Bindings in other buffers are not un-set when we unwind a let-binding which set the default value. There doesn't seem to be an existing test which covers this, so here's one. * test/src/data-tests.el (data-tests--let-buffer-local-no-unwind-other-buffers): Add test for let-binding unwinding behavior
