[patch] PPP frame buffer leakage #75

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The attach patch fixes a bug where a buffer pointer was passed to a function 
expecting a key, rather than a pointer. Unfortunately both the key and the 
buffer pointer were of the same type, so no compiler warnings were issued.

As an effect of this, contention for the PPP send buffers could result in parts 
of the buffer space leaking, and never again becoming available for reuse - in 
turn aggravating the contention, causing further leaks, until the whole send 
buffer space would be lost, and PPP sending would cease (or seize :) completely.

Fixed in r5774.  Thanks; obvious once pointed out, but must have been nasty to 
find.
