CONFIG_NET_DEBUG_NET_PKT_NON_FRAGILE_ACCESS¶
Reduce r/w fragility by resetting the packet cursor when freed
Type: bool
Help¶
This MUST not be used unless you have an hard to catch bug. This will
reset the pkt cursor when it's freed, so any subsequent r/w operations
will not segfault, but just bail out and hopefully it will enable you
to know who/where the packet was freed already. Do not set this, by
any means, unless you are actively debugging.
Defaults¶
No defaults. Implicitly defaults to n
.
