'ndiswrapper' is intentionally tainted by kernel/module.c because it is used to load and run unknown binary / proprietary code in kernel-space. If this unknown binary / proprietary code were to contain a bug (which all code of that complexity tends to), it might write to memory it doesn't own, or coerce a device to do so on its behalf, making a kernel crash dump analysis into a wild goose chase (hence the reason for kernel taint). > Note that when a driver is loaded, ndiswrapper does taint the kernel (to be > more accurate, it should check if the driver being loaded is GPL or not, > but that is not done). Are you saying ndiswrapper voluntarily calls add_taint() whenever it loads an NDIS driver? Are there even any examples of GPL-licensed NDIS drivers? > Thanks, > Giri > Thanks, Chase - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
