From 3bdf4d6641fb34d1c2f130abddb847169a793afe Mon Sep 17 00:00:00 2001 From: Peter Stephenson Date: Tue, 2 Jul 2019 13:42:53 +0100 Subject: 44480: Don't automatically close externally visible file descroptors. These are descriptors marked FDT_EXTERNAL. Make all sysopen'ed file descriptors FDT_EXTERNAL. Make =(...) call closem() consistent with other substitutions. Document file descriptors are left open. --- Src/Modules/system.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'Src/Modules/system.c') diff --git a/Src/Modules/system.c b/Src/Modules/system.c index 7a4f4ee13..50de59cf9 100644 --- a/Src/Modules/system.c +++ b/Src/Modules/system.c @@ -316,7 +316,7 @@ bin_sysopen(char *nam, char **args, Options ops, UNUSED(int func)) int o, fd, moved_fd, explicit = -1; mode_t perms = 0666; #if defined(FD_CLOEXEC) && !defined(O_CLOEXEC) - int fdflags; + int fdflags = 0; #endif if (!OPT_ISSET(ops, 'u')) { @@ -396,8 +396,8 @@ bin_sysopen(char *nam, char **args, Options ops, UNUSED(int func)) #endif /* O_CLOEXEC */ fcntl(moved_fd, F_SETFD, FD_CLOEXEC); #endif /* FD_CLOEXEC */ + fdtable[moved_fd] = FDT_EXTERNAL; if (explicit == -1) { - fdtable[moved_fd] = FDT_EXTERNAL; setiparam(fdvar, moved_fd); /* if setting the variable failed, close moved_fd to avoid leak */ if (errflag) -- cgit 1.4.1
