From ca2a05aa7c72309ee65164c78fa2be7a5038215e Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Sun, 11 Nov 2007 15:43:12 -0500 Subject: [PATCH] nfsd: Fix handling of negative lengths in read_buf() The length "nbytes" passed into read_buf should never be negative, but we check only for too-large values of "nbytes", not for too-small values. Make nbytes unsigned, so it's clear that the former tests are sufficient. (Despite this read_buf() currently correctly returns an xdr error in the case of a negative length, thanks to an unsigned comparison with size_of() and bounds-checking in kmalloc(). This seems very fragile, though.) Signed-off-by: J. Bruce Fields --- Reading git-format-patch failed
