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. |
| 9 |
|
| 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. |
