From b9cc4489c68de59f7a38ef4e02a9829465a6a544 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Wed, 15 Apr 2015 13:23:48 +0930 Subject: params: handle quotes properly for values not of form foo="bar". When starting kernel with arguments like: init=/bin/sh -c "echo arguments" the trailing double quote is not removed which results in following command being executed: /bin/sh -c 'echo arguments"' Reported-by: Arthur Gautier Signed-off-by: Rusty Russell --- kernel/params.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'kernel/params.c') diff --git a/kernel/params.c b/kernel/params.c index 728e05b167de..a22d6a759b1a 100644 --- a/kernel/params.c +++ b/kernel/params.c @@ -173,9 +173,9 @@ static char *next_arg(char *args, char **param, char **val) if (args[i-1] == '"') args[i-1] = '\0'; } - if (quoted && args[i-1] == '"') - args[i-1] = '\0'; } + if (quoted && args[i-1] == '"') + args[i-1] = '\0'; if (args[i]) { args[i] = '\0'; -- cgit v1.2.3
