From 725ad2a8f1358bff885414f5e91d253c99921ddc Mon Sep 17 00:00:00 2001 From: Konstantin Sharlaimov Date: Thu, 30 Aug 2007 06:17:37 +0200 Subject: [PPP]: Fix output buffer size in ppp_decompress_frame(). 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.
