Subject: [PATCH] bcm43xx-d80211 (try 2): Fix an off-by-one condition in handle_irq_noise
Date: Mon, 10 Jul 2006 18:16:01 -0500 [thread overview]
Message-ID: <44B2DFB1.8080204@lwfinger.net> (raw)
An assert statement near the start of handle_irq_noise in the d80211 version of bcm43xx_main.c is
there to protect against out of bound addressing using variable bcm->noisecalc.nr_samples. The
arrays in question have a dimension of 8, thus the value must be < 8. This patch mirrors the one
submitted earlier for the softmac version of bcm43xx.
