As -discussed in -https://gitlab.freedesktop.org/polkit/polkit/-/merge_requests/35 and -verified by the commit author, Duktape has no interrupt injection -mechanism (it has no thread-safe API entry whatsoever, even). Using -DUK_USE_EXEC_TIMEOUT_CHECK is also not feasible, because: - - i) It must be enabled at build time and shared object builds of the - lib on distros go with the default options, something we cannot - change/control - - ii) That does not account for non-ECMAScript explicit execution - contexts, like regex execution, native C calls, etc. - -It has been agreed, on that thread, that pthread_cond_timedwait()-ing -and having proper Duktape evaluation/execution calls take place in a -separate thread, to be killed after the runaway script killer's -accorded timeout value, a reasonable approach. We have considered -using glib wrappers for direct pthread usage, but that way would make -it impossible to issue -pthread_setcanceltype(PTHREAD_CANCEL_ASYNCHRONOUS, ...) and we want to -be paranoid in that regard. - -On Duktape, we don't get to err from the JS context (to be captured by -the offending script), but to be forcibly killed on timeout scenarios, -leading to null returns, thus polkit negation, by definition. It's a -reasonable design/compromise. - -A fatal error handler routine, for the Duktape context, has also been -added, using the polkit_backend_authority_log() logging infra to -better assist users on what went wrong. - -Finally, the script evaluation routine has been made to use -duk_peval_lstring() (previously using _noresult variant), so to able -to present the user with proper error messages, should any occur. - -The original runaway script killer test has been adjusted to please -both JS backends. - -Signed-off-by: Gustavo Lima Chaves <gustavo.chaves@microsoft.com> ---- - meson.build | 1 + - src/polkitbackend/meson.build | 1 + - src/polkitbackend/polkitbackendcommon.h | 2 + - .../polkitbackendduktapeauthority.c | 236 ++++++++++++++---- - .../polkitbackendjsauthority.cpp | 10 +- - .../etc/polkit-1/rules.d/10-testing.rules | 6 +- - .../test-polkitbackendjsauthority.c | 2 +- - 7 files changed, 209 insertions(+), 49 deletions(-) - -diff --git a/meson.build b/meson.build -index 4e44723..46956e3 100644 ---- a/meson.build -+++ b/meson.build -@@ -137,6 +137,7 @@ js_engine = get_option('js_engine') - if js_engine == 'duktape' - js_dep = dependency('duktape') - libm_dep = cc.find_library('m') -+ libpthread_dep = cc.find_library('pthread') - elif js_engine == 'mozjs' - js_dep = dependency('mozjs-78') - endif -diff --git a/src/polkitbackend/meson.build b/src/polkitbackend/meson.build -index 9ec01b2..4dfea39 100644 ---- a/src/polkitbackend/meson.build -+++ b/src/polkitbackend/meson.build -@@ -34,6 +34,7 @@ c_flags = [ - if js_engine == 'duktape' - sources += files('polkitbackendduktapeauthority.c') - deps += libm_dep -+ deps += libpthread_dep - elif js_engine == 'mozjs' - sources += files('polkitbackendjsauthority.cpp') - endif -diff --git a/src/polkitbackend/polkitbackendcommon.h b/src/polkitbackend/polkitbackendcommon.h -index 6d0d267..dd700fc 100644 ---- a/src/polkitbackend/polkitbackendcommon.h -+++ b/src/polkitbackend/polkitbackendcommon.h -@@ -50,6 +50,8 @@ - #include <systemd/sd-login.h> - #endif /* HAVE_LIBSYSTEMD */ - -+#define RUNAWAY_KILLER_TIMEOUT (15) -+ - #ifdef __cplusplus - extern "C" { - #endif -diff --git a/src/polkitbackend/polkitbackendduktapeauthority.c b/src/polkitbackend/polkitbackendduktapeauthority.c -index a2b4420..80f1976 100644 ---- a/src/polkitbackend/polkitbackendduktapeauthority.c -+++ b/src/polkitbackend/polkitbackendduktapeauthority.c -@@ -47,8 +47,20 @@ struct _PolkitBackendJsAuthorityPrivate - GFileMonitor **dir_monitors;
