From 19de71f9fa023cb8a2b067a6db2f57ee4fad9f5d Mon Sep 17 00:00:00 2001 From: Konstantin Sharlaimov Date: Tue, 21 Aug 2007 21:20:25 -0700 Subject: [PATCH] PPP: Fix PPP buffer sizing. This patch addresses the issue with "osize too small" errors in mppe encryption. The patch fixes the issue with wrong output buffer size being passed to ppp decompression routine. -------------------- As pointed out by Suresh Mahalingam, the issue addressed by ppp-fix-osize-too-small-errors-when-decoding patch is not fully resolved yet. The size of allocated output buffer is correct, however it size passed to ppp->rcomp->decompress in ppp_generic.c if wrong. The patch fixes that. -------------------- Signed-off-by: Konstantin Sharlaimov Signed-off-by: David S.
