We do this by moving multicast memberships 7437c478bd9Sstevel@tonic-gate * to a new_ill within the group.

But, we 7467c478bd9Sstevel@tonic-gate * need to be able to delete memberships which will still come down 7477c478bd9Sstevel@tonic-gate * with the ifindex of the old ill which is what the application 7487c478bd9Sstevel@tonic-gate * knows of. Thus we store the ilm_/ilg_orig_ifindex to keep track 7497c478bd9Sstevel@tonic-gate * of where we joined initially so that we can lookup even after we 7507c478bd9Sstevel@tonic-gate * moved the membership. It is also used for moving back the membership 7517c478bd9Sstevel@tonic-gate * when the old ill has been repaired. This is done by looking up for 7527c478bd9Sstevel@tonic-gate * ilms with ilm_orig_ifindex matching on the old ill's ifindex. Only 7537c478bd9Sstevel@tonic-gate * ilms actually move from old ill to new ill. ilgs don't move (just 7547c478bd9Sstevel@tonic-gate * the ilg_ill is changed when it moves) as it just records the state 7557c478bd9Sstevel@tonic-gate * of the application that has joined a group G where as ilm records 7567c478bd9Sstevel@tonic-gate * the state joined with the driver. Thus when we send DL_XXXMULTI_REQs 7577c478bd9Sstevel@tonic-gate * we also need to keep the ilm in the right ill. 7587c478bd9Sstevel@tonic-gate * 7597c478bd9Sstevel@tonic-gate * In IPv4, as ipifs move from old ill to new_ill, ilgs and ilms move 7607c478bd9Sstevel@tonic-gate * implicitly as we use only ipifs in IPv4.

If it finds an IRE, it bumps up the 21897c478bd9Sstevel@tonic-gate * reference count before dropping the lock. Sometimes we *may* want 21907c478bd9Sstevel@tonic-gate * to bump up the reference count after we *looked* up i.e without 21917c478bd9Sstevel@tonic-gate * holding the bucket lock. So, the IRE_REFHOLD macro does not assert 21927c478bd9Sstevel@tonic-gate * on the bucket lock being held. Any thread trying to delete from 21937c478bd9Sstevel@tonic-gate * the hash bucket can still do so but cannot free the IRE if 21947c478bd9Sstevel@tonic-gate * ire_refcnt is not 0. 21957c478bd9Sstevel@tonic-gate * 21967c478bd9Sstevel@tonic-gate * 2) We bump up the reference count on the bucket where the IRE resides 21977c478bd9Sstevel@tonic-gate * (IRB), when we want to prevent the IREs getting deleted from a given 21987c478bd9Sstevel@tonic-gate * hash bucket. This makes life easier for ire_walk type functions which 21997c478bd9Sstevel@tonic-gate * wants to walk the IRE list, call a function, but needs to drop 22007c478bd9Sstevel@tonic-gate * the bucket lock to prevent recursive rw_enters. While the 22017c478bd9Sstevel@tonic-gate * lock is dropped, the list could be changed by other threads or 22027c478bd9Sstevel@tonic-gate * the same thread could end up deleting the ire or the ire pointed by 22037c478bd9Sstevel@tonic-gate * ire_next. IRE_REFHOLDing the ire or ire_next is not sufficient as 22047c478bd9Sstevel@tonic-gate * a delete will still remove the ire from the bucket while we have 22057c478bd9Sstevel@tonic-gate * dropped the lock and hence the ire_next would be NULL. Thus, we 22067c478bd9Sstevel@tonic-gate * need a mechanism to prevent deletions from a given bucket. 22077c478bd9Sstevel@tonic-gate * 22087c478bd9Sstevel@tonic-gate * To prevent deletions, we bump up the reference count on the 22097c478bd9Sstevel@tonic-gate * bucket. If the bucket is held, ire_delete just marks IRE_MARK_CONDEMNED 22107c478bd9Sstevel@tonic-gate * both on the ire's ire_marks and the bucket's irb_marks. When the 22117c478bd9Sstevel@tonic-gate * reference count on the bucket drops to zero, all the CONDEMNED ires 22127c478bd9Sstevel@tonic-gate * are deleted. We don't have to bump up the reference count on the 22137c478bd9Sstevel@tonic-gate * bucket if we are walking the bucket and never have to drop the bucket 22147c478bd9Sstevel@tonic-gate * lock. Note that IRB_REFHOLD does not prevent addition of new ires 22157c478bd9Sstevel@tonic-gate * in the list. It is okay because addition of new ires will not cause 22167c478bd9Sstevel@tonic-gate * ire_next to point to freed memory. We do IRB_REFHOLD only when 22177c478bd9Sstevel@tonic-gate * all of the 3 conditions are true : 22187c478bd9Sstevel@tonic-gate * 22197c478bd9Sstevel@tonic-gate * 1) The code needs to walk the IRE bucket from start to end. 22207c478bd9Sstevel@tonic-gate * 2) It may have to drop the bucket lock sometimes while doing (1) 22217c478bd9Sstevel@tonic-gate * 3) It does not want any ires to be deleted meanwhile. 22227c478bd9Sstevel@tonic-gate */ 22237c478bd9Sstevel@tonic-gate 22247c478bd9Sstevel@tonic-gate /* 22257c478bd9Sstevel@tonic-gate * Bump up the reference count on the IRE.
