[PATCH] coverity: ipmi_msghandler() channels array overrun fix
We fix the check in 1084, which was
1084 if (addr->channel > IPMI_NUM_CHANNELS) {
1085 spin_lock_irqsave(&intf->counter_lock, flags);
1086 intf->sent_invalid_commands++;
1087 spin_unlock_irqrestore(&intf->counter_lock, flags);
1088 rv = -EINVAL;
1089 goto out_err;
1090 }
addr->channel is used in
1092 if (intf->channels[addr->channel].medium
Definitions involved:
221 struct ipmi_channel channels[IPMI_MAX_CHANNELS];
134 #define IPMI_MAX_CHANNELS 8
In /linux-2.6.12-rc6/include/linux/ipmi.h
148 #define IPMI_NUM_CHANNELS 0x10
