Subject: out-of-bounds array index
Date: Thu, 7 Feb 2008 19:56:43 +0100	[thread overview]
Message-ID: <20080207185642.GN15220@kernel.dk> (raw)

Hi,

Just saw this from gcc:

drivers/char/drm/i915_drv.c: In function ?i915_suspend?:
drivers/char/drm/i915_drv.c:173: warning: array subscript is above array
bounds
  CC [M]  drivers/char/drm/i915_dma.o
drivers/char/drm/i915_drv.c: In function ?i915_resume?:
drivers/char/drm/i915_drv.c:220: warning: array subscript is above array
bounds

It's this code:

        dev_priv->saveGR[0x18] =
                i915_read_indexed(VGA_GR_INDEX, VGA_GR_DATA, 0x18);

which looks legit, since saveGR is

        u8 saveGR[24];

It has been introduced by commit
ba8bbcf6ff4650712f64c0ef61139c73898e2165, which seems to be you Jesse.
