Created attachment 131827 [details, diff]
hardened-sources-2.6.20-r6-pwc.patch

trivial fix

[Comment 2 Natanael Copa 2007-09-25 07:28:39 UTC]

As mentioned in the forum that i linked to, this is probably not related to
gresc/hardened at all. Patch belongs more likely in genpatches.

thanks

This is supposed to be fixed in .21, but I incorporated the fix into genpatches-2.6.20.

You might wanna sent that do Willy Tarreau / LKML for inclusion into the next stable series.

The patch is in genpatches, and also in hardened-sources-2.6.20-r10 (stable).

I re-emerge hardened sources this morning and the patch was not there.

You're right, it is in genpatches but not in hardened-sources-2.6.20-r10, sorry about that. Will reopen this bug until we have a version for you to upgrade to.

[Comment 8 Maarten Bressers (RETIRED) 2007-10-10 19:45:22 UTC]

The patch has just been added to hardened-sources-2.6.20-r10, sorry for the delay (you might want to wait a little while before syncing so you're sure to get it).
