Date: Sun, 26 Dec 2010 22:14:01 +0100 (CET) From: Jesper Juhl <jj@...osbits.net> To: DL-MPTFusionLinux@....com cc: Eric Moore <Eric.Moore@....com>, linux-scsi@...r.kernel.org, linux-kernel@...r.kernel.org, support@....com Subject: [PATCH] SCSI, LSI Fusion MPT: Fix memory leak in mptctl_getiocinfo() Hi, A 'kfree(karg)' is missing in a failure path in drivers/message/fusion/mptctl.c::mptctl_getiocinfo() which can cause a memory leak. This patch should take care of that. Hope I didn't miss something obvious, but to me it looks like adding this kfree() is the right thing to do. If you disagree feel free to correct me :-) Signed-off-by: Jesper Juhl <jj@...osbits.net> --- mptctl.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) compile tested only since I don't have proper hardware to test for real. diff --git a/drivers/message/fusion/mptctl.c b/drivers/message/fusion/mptctl.c index a3856ed..1dcc13a 100644 --- a/drivers/message/fusion/mptctl.c +++ b/drivers/message/fusion/mptctl.c @@ -1307,8 +1307,10 @@ mptctl_getiocinfo (unsigned long arg, unsigned int data_size) else karg->adapterType = MPT_IOCTL_INTERFACE_SCSI; - if (karg->hdr.port > 1) + if (karg->hdr.port > 1) { + kfree(karg); return -EINVAL; + } port = karg->hdr.port; karg->port = port; -- Jesper Juhl <jj@...osbits.net> http://www.chaosbits.net/ Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
