The filter_remove function removes the specified filter from the specified filter stack, destroying a filter layer. If the specified filter was inserted into the filter stack multiple times, only that filter’s topmost filter layer is destroyed.

When possible, plug-in developers should avoid calling filter_remove directly, and instead use the remove-filter SAF applicable in Input-, Output-, Service-, and Error-class directives.


int filter_remove(SYS_NETFD sd, const Filter *filter);


Returns REQ_PROCEED if the specified filter was removed successfully or REQ_NOACTION if the specified filter was not part of the filter stack. Any other return value indicates an error.


SYS_NETFD sd is the filter stack, sn->csd.

const Filter *filter is the filter to remove.
