After some google-ing, I found the recent mremap() kernel patch. I've tacked it to the end of this message just for completeness.
How could I have gotten this information using Debian tools and/or infrastructure (rather than google etc.)? I tried: apt-get update apt-get source kernel-source-2.4.18 ... which I know from http://www.debian.org/security/2004/dsa-413 has the diff in there, but it's not separated out into a debian/patches directory like I've seen in some source packages; it's combined with many other patches in a single file: kernel-source-2.4.18_2.4.18-14.1.diff.gz Should I stick to google or is there a better way...? Thanks, - Tor (Redhat Oldie, Debian Newbie) PS - Is a debian/patches directory (a la dpatch or dbs) for source archives the wave of the future? It seems preferable to me (but then, I'm not a maintainer...). ------------------------------------------------------------------------ --- kernel-source-2.4.18-2.4.18.orig/mm/mremap.c +++ kernel-source-2.4.18-2.4.18/mm/mremap.c @@ -236,6 +236,14 @@ if (new_len > TASK_SIZE || new_addr > TASK_SIZE - new_len) goto out; + + /* + * Allow new_len == 0 only if new_addr == addr + * to preserve truncation in place (that was working + * safe and some app may depend on it). + */ + if (unlikely(!new_len && new_addr != addr)) + goto out; /* Check if the location we're moving into overlaps * the * old location at all, and fail if it does. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
