4 Subject: [PATCH] [PPP]: Fix output buffer size in ppp_decompress_frame().
5
6 This patch addresses the issue with "osize too small" errors in mppe
7 encryption. The patch fixes the issue with wrong output buffer size
8 being passed to ppp decompression routine.

10 --------------------
11 As pointed out by Suresh Mahalingam, the issue addressed by
12 ppp-fix-osize-too-small-errors-when-decoding patch is not fully resolved yet.
13 The size of allocated output buffer is correct, however it size passed to
14 ppp->rcomp->decompress in ppp_generic.c if wrong. The patch fixes that.
