We do this by moving multicast memberships 8007c478bd9Sstevel@tonic-gate * to a new_ill within the group.

But, we 8037c478bd9Sstevel@tonic-gate * need to be able to delete memberships which will still come down 8047c478bd9Sstevel@tonic-gate * with the ifindex of the old ill which is what the application 8057c478bd9Sstevel@tonic-gate * knows of. Thus we store the ilm_/ilg_orig_ifindex to keep track 8067c478bd9Sstevel@tonic-gate * of where we joined initially so that we can lookup even after we 8077c478bd9Sstevel@tonic-gate * moved the membership. It is also used for moving back the membership 8087c478bd9Sstevel@tonic-gate * when the old ill has been repaired. This is done by looking up for 8097c478bd9Sstevel@tonic-gate * ilms with ilm_orig_ifindex matching on the old ill's ifindex. Only 8107c478bd9Sstevel@tonic-gate * ilms actually move from old ill to new ill. ilgs don't move (just 8117c478bd9Sstevel@tonic-gate * the ilg_ill is changed when it moves) as it just records the state 8127c478bd9Sstevel@tonic-gate * of the application that has joined a group G where as ilm records 8137c478bd9Sstevel@tonic-gate * the state joined with the driver.

If it finds an IRE, it bumps up the 22737c478bd9Sstevel@tonic-gate * reference count before dropping the lock. Sometimes we *may* want 22747c478bd9Sstevel@tonic-gate * to bump up the reference count after we *looked* up i.e without 22757c478bd9Sstevel@tonic-gate * holding the bucket lock. So, the IRE_REFHOLD macro does not assert 22767c478bd9Sstevel@tonic-gate * on the bucket lock being held. Any thread trying to delete from 22777c478bd9Sstevel@tonic-gate * the hash bucket can still do so but cannot free the IRE if 22787c478bd9Sstevel@tonic-gate * ire_refcnt is not 0. 22797c478bd9Sstevel@tonic-gate * 22807c478bd9Sstevel@tonic-gate * 2) We bump up the reference count on the bucket where the IRE resides 22817c478bd9Sstevel@tonic-gate * (IRB), when we want to prevent the IREs getting deleted from a given 22827c478bd9Sstevel@tonic-gate * hash bucket. This makes life easier for ire_walk type functions which 22837c478bd9Sstevel@tonic-gate * wants to walk the IRE list, call a function, but needs to drop 22847c478bd9Sstevel@tonic-gate * the bucket lock to prevent recursive rw_enters. While the 22857c478bd9Sstevel@tonic-gate * lock is dropped, the list could be changed by other threads or 22867c478bd9Sstevel@tonic-gate * the same thread could end up deleting the ire or the ire pointed by 22877c478bd9Sstevel@tonic-gate * ire_next. IRE_REFHOLDing the ire or ire_next is not sufficient as 22887c478bd9Sstevel@tonic-gate * a delete will still remove the ire from the bucket while we have 22897c478bd9Sstevel@tonic-gate * dropped the lock and hence the ire_next would be NULL. Thus, we 22907c478bd9Sstevel@tonic-gate * need a mechanism to prevent deletions from a given bucket. 22917c478bd9Sstevel@tonic-gate * 22927c478bd9Sstevel@tonic-gate * To prevent deletions, we bump up the reference count on the 22937c478bd9Sstevel@tonic-gate * bucket. If the bucket is held, ire_delete just marks IRE_MARK_CONDEMNED 22947c478bd9Sstevel@tonic-gate * both on the ire's ire_marks and the bucket's irb_marks. When the 22957c478bd9Sstevel@tonic-gate * reference count on the bucket drops to zero, all the CONDEMNED ires 22967c478bd9Sstevel@tonic-gate * are deleted. We don't have to bump up the reference count on the 22977c478bd9Sstevel@tonic-gate * bucket if we are walking the bucket and never have to drop the bucket 22987c478bd9Sstevel@tonic-gate * lock. Note that IRB_REFHOLD does not prevent addition of new ires 22997c478bd9Sstevel@tonic-gate * in the list. It is okay because addition of new ires will not cause 23007c478bd9Sstevel@tonic-gate * ire_next to point to freed memory.
