We found I think three call sites which were incorrectly ignoring the strstrip() return value and it's reasonable to fear that others will make the same mistake in the future. And maybe ipr.c _should_ be patched. Right now it's assuming that the string coming back from the device has no leading whitespace. Why trim any possible trailing whitespace but not trim any possible leading whitespace? Or.. /* * Comment goes here */ static inline void strsrip_tail(char *str) { char *x __used; x = strstrip(str); } -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
