[tor/release-0.3.5] Better fix for #40241 (--enable-all-bugs-are-fatal and fallthrough)
by nickm＠torproject.org 19 Jan '21

19 Jan '21

commit fa8ecf88202dfe3af9e02331ca9dee6768870911 Author: Nick Mathewson <nickm(a)torproject.org> Date: Wed Jan 13 09:48:00 2021 -0500 Better fix for #40241 (--enable-all-bugs-are-fatal and fallthrough) This one should work on GCC _and_ on Clang. The previous version made Clang happier by not having unreachable "fallthrough" statements, but made GCC sad because GCC didn't think that the unconditional failures were really unconditional, and therefore _wanted_ a FALLTHROUGH. This patch adds a FALLTHROUGH_UNLESS_ALL_BUGS_ARE_FATAL macro that seems to please both GCC and Clang in this case: ordinarily it is a FALLTHROUGH, but when ALL_BUGS_ARE_FATAL is defined, it's an abort(). Fixes bug 40241 again. Bugfix on earlier fix for 40241, which was merged into maint-0.3.5 and forward, and released in 0.4.5.3-rc. --- changes/40241_v2 | 4 ++++ src/core/or/channeltls.c | 4 +--- src/core/or/circuitlist.c | 4 +--- src/feature/client/entrynodes.c | 4 +--- src/feature/rend/rendclient.c | 4 +--- src/lib/log/util_bug.h | 11 +++++++++++ 6 files changed, 19 insertions(+), 12 deletions(-) diff --git a/changes/40241_v2 b/changes/40241_v2 new file mode 100644 index 0000000000..85038297f7 --- /dev/null +++ b/changes/40241_v2 @@ -0,0 +1,4 @@ + o Minor bugfixes (compilation): + - Fix another warning about unreachable fallthrough annotations + when building with "--enable-all-bugs-are-fatal" on some compilers. + Fixes bug 40241; bugfix on 0.4.5.3-rc. diff --git a/src/core/or/channeltls.c b/src/core/or/channeltls.c index bdd82f3138..18025ff73a 100644 --- a/src/core/or/channeltls.c +++ b/src/core/or/channeltls.c @@ -1225,9 +1225,7 @@ channel_tls_handle_var_cell(var_cell_t *var_cell, or_connection_t *conn) * the v2 and v3 handshakes. */ /* But that should be happening any longer've disabled bufferevents. */ tor_assert_nonfatal_unreached_once(); -#ifndef ALL_BUGS_ARE_FATAL - FALLTHROUGH; -#endif + FALLTHROUGH_UNLESS_ALL_BUGS_ARE_FATAL; case OR_CONN_STATE_TLS_SERVER_RENEGOTIATING: if (!(command_allowed_before_handshake(var_cell->command))) { log_fn(LOG_PROTOCOL_WARN, LD_PROTOCOL, diff --git a/src/core/or/circuitlist.c b/src/core/or/circuitlist.c index 83e2124498..ccf3041bb4 100644 --- a/src/core/or/circuitlist.c +++ b/src/core/or/circuitlist.c @@ -787,9 +787,7 @@ circuit_purpose_to_controller_hs_state_string(uint8_t purpose) "Unrecognized circuit purpose: %d", (int)purpose); tor_fragile_assert(); -#ifndef ALL_BUGS_ARE_FATAL - FALLTHROUGH; -#endif + FALLTHROUGH_UNLESS_ALL_BUGS_ARE_FATAL; case CIRCUIT_PURPOSE_OR: case CIRCUIT_PURPOSE_C_GENERAL: diff --git a/src/feature/client/entrynodes.c b/src/feature/client/entrynodes.c index c930fe244f..6c7f8057bd 100644 --- a/src/feature/client/entrynodes.c +++ b/src/feature/client/entrynodes.c @@ -2263,9 +2263,7 @@ entry_guards_note_guard_success(guard_selection_t *gs, break; default: tor_assert_nonfatal_unreached(); -#ifndef ALL_BUGS_ARE_FATAL - FALLTHROUGH; -#endif + FALLTHROUGH_UNLESS_ALL_BUGS_ARE_FATAL; case GUARD_CIRC_STATE_USABLE_IF_NO_BETTER_GUARD: if (guard->is_primary) { /* XXXX #20832 -- I don't actually like this logic.
