* The vnode_free_list_mtx is required unconditionally when iteratingKonstantin Belousov2012-12-031-4/+28
| | | | | | | | | | | | | | | | | | | | | | | | over the active list. The mount interlock is not enough to guarantee the validity of the tailq link pointers. The __mnt_vnode_next_active() and __mnt_vnode_first_active() active lists iterators helper functions did not provided the neccessary stability for the list, allowing the iterators to pick garbage. This was uncovered after the r243599 made the active list iterators non-nop. Since a vnode interlock is before the vnode_free_list_mtx, obtain the vnode ilock in the non-blocking manner when under vnode_free_list_mtx, and restart iteration after the yield if the lock attempt failed. Assert that a vnode found on the list is active, and assert that the helpers return the vnode with interlock owned.

* Don't grab the PCU lock inside the TX lock.Adrian Chadd2012-12-021-2/+2

* Delete the per-TXQ locks and replace them with a single TX lock.Adrian Chadd2012-12-026-173/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I couldn't think of a way to maintain the hardware TXQ locks _and_ layer on top of that per-TXQ software queuing and any other kind of fine-grained locks (eg per-TID, or per-node locks.) So for now, to facilitate some further code refactoring and development as part of the final push to get software queue ps-poll and u-apsd handling into this driver, just do away with them entirely. I may eventually bring them back at some point, when it looks slightly more architectually cleaner to do so. But as it stands at the present, it's not really buying us much: * in order to properly serialise things and not get bitten by scheduling and locking interactions with things higher up in the stack, we need to wrap the whole TX path in a long held lock. Otherwise we can end up being pre-empted during frame handling, resulting in some out of order frame handling between sequence number allocation and encryption handling (ie, the seqno and the CCMP IV get out of sequence); * .. so whilst that's the case, holding the lock for that long means that we're acquiring and releasing the TXQ lock _inside_ that context; * And we also acquire it per-frame during frame completion, but we currently can't hold the lock for the duration of the TX completion as we need to call net80211 layer things with the locks _unheld_ to avoid LOR. * .. the other places were grab that lock are reset/flush, which don't happen often. My eventual aim is to change the TX path so all rejected frame transmissions and all frame completions result in any ieee80211_free_node() calls to occur outside of the TX lock; then I can cut back on the amount of locking that goes on here. There may be some LORs that occur when ieee80211_free_node() is called when the TX queue path fails; I'll begin to address these in follow-up commits. Notes: svn path=/head/; revision=243786

* ioapic_program_intpin: program high bits before low bitsAndriy Gapon2012-12-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | Programming the low bits has a side-effect if unmasking the pin if it is not disabled. So if an interrupt was pending then it would be delivered with the correct new vector but to the incorrect old LAPIC. This fix could be made clearer by preserving the mask bit while programming the low bits and then explicitly resetting the mask bit after all the programming is done. Probability to trip over the fixed bug could be increased by bootverbose because printing of the interrupt information in ioapic_assign_cpu lengthened the time window during which an interrupt could arrive while a pin is masked.

The bad code was plain incorrect: (a) it spoiled handling of v_usecount reaching zero and (b) it leaked v_holdcnt. The ugly code employs potentially unsafe locking tricks. Ideally we should separate vnode lifecycle and gfs node lifecycle. A gfs node should have its own reference count where its child nodes should be accounted.

| | | | | | | | | | | | | | | | | | | | | | Currently when we discover that trail file is greater than configured limit we send AUDIT_TRIGGER_ROTATE_KERNEL trigger to the auditd daemon once. If for some reason auditd didn't rotate trail file it will never be rotated. Change it by sending the trigger when trail file size grows by the configured limit. For example if the limit is 1MB, we will send trigger on 1MB, 2MB, 3MB, etc. This is also needed for the auditd change that will be committed soon where auditd may ignore the trigger - it might be ignored if kernel requests the trail file to be rotated too quickly (often than once a second) which would result in overwriting previous trail file.

| | | | | | | | | | | | | | | | | | | Currently on each record write we call VFS_STATFS() to get available space on the file system as well as VOP_GETATTR() to get trail file size. We can assume that trail file is only updated by the audit worker, so instead of asking for file size on every write, get file size on trail switch only (it should be zero, but it's not expensive) and use global variable audit_size protected by the audit worker lock to keep track of trail file's size. This eliminates VOP_GETATTR() call for every write. VFS_STATFS() is satisfied from in-memory data (mount->mnt_stat), so shouldn't be expensive.
