The `GUIX_RKTIO_PATCH_BIN_SH` macro is defined; and - - 2. `rktio_process` is called with the exact path "/bin/sh"; and - - 3. The path specified by `GUIX_RKTIO_PATCH_BIN_SH` does exists; - -then `rktio_process` will execute the file specified -by `GUIX_RKTIO_PATCH_BIN_SH` instead of "/bin/sh". - -Compared to previous attempts to patch the Racket sources, -making this change at the C level is both: - - - More comprehensive: it catches all attempts to execute "/bin/sh", - without having to track down the source of every occurance; and - - - Less intrusive: by guarding the special case with a C preprocessor - conditional and a runtime check that the file in the store exists, - we make it much less likely that it will "leak" out of Guix. ---- - racket/src/rktio/rktio_process.c | 21 ++++++++++++++++++++- - 1 file changed, 20 insertions(+), 1 deletion(-) - -diff --git a/racket/src/rktio/rktio_process.c b/racket/src/rktio/rktio_process.c -index 89202436c0..465ebdd5c5 100644 ---- a/racket/src/rktio/rktio_process.c -+++ b/racket/src/rktio/rktio_process.c -@@ -1224,12 +1224,14 @@ int rktio_process_allowed_flags(rktio_t *rktio) - /*========================================================================*/ - - rktio_process_result_t *rktio_process(rktio_t *rktio, -- const char *command, int argc, rktio_const_string_t *argv, -+ /* PATCHED for Guix (next line) */ -+ const char *_guix_orig_command, int argc, rktio_const_string_t *argv, - rktio_fd_t *stdout_fd, rktio_fd_t *stdin_fd, rktio_fd_t *stderr_fd, - rktio_process_t *group_proc, - const char *current_directory, rktio_envvars_t *envvars, - int flags) - { -+ const char *command; /* PATCHED for Guix */ - rktio_process_result_t *result; - intptr_t to_subprocess[2], from_subprocess[2], err_subprocess[2]; - int pid; -@@ -1255,6 +1257,23 @@ rktio_process_result_t *rktio_process(rktio_t *rktio, - int i; - #endif - -+/* BEGIN PATCH for Guix */ -+#if defined(GUIX_RKTIO_PATCH_BIN_SH) -+# define GUIX_AS_a_STR_HELPER(x) #x -+# define GUIX_AS_a_STR(x) GUIX_AS_a_STR_HELPER(x) -+ /* A level of indirection makes `#` work as needed: */ -+ command = -+ ((0 == strcmp(_guix_orig_command, "/bin/sh")) -+ && rktio_file_exists(rktio, GUIX_AS_a_STR(GUIX_RKTIO_PATCH_BIN_SH))) -+ ?
