Subject: [PPP_MPPE]: Fix "osize too small" check.
X-Git-Tag: v2.6.22-rc5~39^2~6
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=606f585e363527da9feaed79465132c0c661fd9e;p=pandora-kernel.git

[PPP_MPPE]: Fix "osize too small" check.

Prevent mppe_decompress() from generating "osize too small" errors when
checking for output buffer size.  When receiving a packet of mru size the
output buffer for decrypted data is 1 byte too small since
mppe_decompress() tries to account for possible PFC, however later in code
it is assumed no PFC.

Adjusting the check prevented these errors from occurring.
