From 33ae9569a4337868d706fe008db872c4824cc628 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 20 Mar 2014 14:14:30 +0000 Subject: [PATCH] busybox: fix existing "export -n" in ash Minor fix to existing patch which did not correctly implement -n support for the export command in ash. The VEXPORT flag of a variable was set in the first call to setvareq() and then remained set in the subsequent call, because the variable already existed in the environment. Although /lib/functions.sh by default does not export variables (NO_EXPORT=1), this issue was leading to dirty environments. Without this fix: (ash) export A=1; export -n B=2; /bin/ash -c "echo \$A, \$B" 1, 2 With this fix: (ash) export A=1; export -n B=2; /bin/ash -c "echo \$A, \$B" 1, Signed-off-by: Christophe Lermytte SVN-Revision: 39968 --- package/utils/busybox/patches/250-ash_export-n.patch | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/package/utils/busybox/patches/250-ash_export-n.patch b/package/utils/busybox/patches/250-ash_export-n.patch index 048c236b85..ddbe74ee29 100644 --- a/package/utils/busybox/patches/250-ash_export-n.patch +++ b/package/utils/busybox/patches/250-ash_export-n.patch @@ -19,7 +19,7 @@ aptr = argptr; name = *aptr; if (name) { -@@ -12624,10 +12633,12 @@ exportcmd(int argc UNUSED_PARAM, char ** +@@ -12624,10 +12633,11 @@ exportcmd(int argc UNUSED_PARAM, char ** vp = *findvar(hashvar(name), name); if (vp) { vp->flags |= flag; @@ -27,7 +27,7 @@ continue; } } - setvar(name, p, flag); +- setvar(name, p, flag); + setvar(name, p, flag & mask); } while ((name = *++aptr) != NULL); return 0; -- 2.25.1
