* tcp: Missing mfree in rack and bbrRandall Stewart2021-06-142-1/+6
| | | | | | | | | | | | | | | | | Recently (Nov) we added logic that protects against a peer negotiating a timestamp, and then not including a timestamp. This involved in the input path doing a goto done_with_input label. Now I suspect the code was cribbed from one in Rack that has to do with the SYN. This had a bug, i.e. it should have a m_freem(m) before going to the label (bbr had this missing m_freem() but rack did not). This then caused the missing m_freem to show up in both BBR and Rack. Also looking at the code referencing m->m_pkthdr.lro_nsegs later (after processing) is not a good idea, even though its only for logging. Best to copy that off before any frees can take place.

* tcp: Mbuf leak while holding a socket buffer lock.Randall Stewart2021-06-144-52/+84
| | | | | | | | | | | | | | | | | | | | | | | When running at NF the current Rack and BBR changes with the recent commits from Richard that cause the socket buffer lock to be held over the ip_output() call and then finally culminating in a call to tcp_handle_wakeup() we get a lot of leaked mbufs. I don't think that this leak is actually caused by holding the lock or what Richard has done, but is exposing some other bug that has probably been lying dormant for a long time. I will continue to look (using his changes) at what is going on to try to root cause out the issue. In the meantime I can't leave the leaks out for everyone else. So this commit will revert all of Richards changes and move both Rack and BBR back to just doing the old sorwakeup_locked() calls after messing with the so_rcv buffer. We may want to look at adding back in Richards changes after I have pinpointed the root cause of the mbuf leak and fixed it.

* tcp: LRO timestamps have lost their previous precisionRandall Stewart2021-06-143-12/+26
| | | | | | | | | | | | | Recently we had a rewrite to tcp_lro.c that was tested but one subtle change was the move to a less precise timestamp. This causes all kinds of chaos in tcp's that do pacing and needs to be fixed to use the more precise time that was there before.

* arm64: Fix pmap_copy()'s handling of 2MB mappingsMark Johnston2021-06-141-5/+2
| | | | | | | | | | | | | | | | | | | | When copying mappings from parent to child, we clear the accessed and dirty bits. This is done for both 4KB and 2MB PTEs. However, pmap_demote_l2() asserts that writable superpages must be dirty. This is to avoid races with the MMU setting the dirty bit during promotion and demotion. pmap_copy() can create clean, writable superpage mappings, so it violates this assertion. Modify pmap_copy() to preserve the accessed and dirty bits when copying 2MB mappings, like we do on amd64.

* riscv: Handle hardware-managed dirty bit updates in pmap_promote_l2()Mark Johnston2021-06-141-9/+32
| | | | | | | | | | | | | | | | | | | pmap_promote_l2() failed to handle implementations which set the accessed and dirty flags. In particular, when comparing the attributes of a run of 512 PTEs, we must handle the possibility that the hardware will set PTE_D on a clean, writable mapping. Following the example of amd64 and arm64, change riscv's pmap_promote_l2() to downgrade clean, writable mappings to read-only, so that updates are synchronized by the pmap lock.

| | | | | | | | | | | | | | | | During boot we warn that the kbd and openfirm drivers are Giant-locked and may be deleted. Generally, the warning helps signal that certain old drivers are not being maintained and are subject to removal, but this doesn't really apply to certain drivers which are harder to detangle from Giant.

* arm64: Use the right PTE when downgrading perms in pmap_promote_l2()Mark Johnston2021-06-141-1/+10
| | | | | | | | | | | | | | | | | | When promoting a run of small mappings to a superpage, we have to downgrade clean, writable mappings to read-only, to handle the possibility that the MMU will concurrently mark one of the mappings as dirty. The code which performed this operation for the first PTE in the run used the wrong PTE pointer. As a result, the comparison would always fail, aborting the promotion. This only occurs when promoting writable, clean mappings.

As far as I can tell, the only fields that libzfs cares about are the filesystem's name, mountpoint, fstypename, and mount flags. Those things are always updated on mount and unmount, so they will always be accurate in the VFS's mount cache except in two circumstances: 1) When a file system is busy unmounting 2) When a ZFS file system changes the value of a mount-overridable property like atime or setuid, but doesn't remount the file system. Right now that only happens when the property is changed by an unprivileged user who has delegated authority to change the property but not to mount the dataset. But perhaps libzfs could choose to do it for other reasons in the future. Switching to `MNT_NOWAIT` will greatly improve speed with no downside, as long as we explicitly update the mount cache whenever we change a mount-overridable property. For comparison, Illumos gets this information using the native `getmntany` and `getmntent` functions, which also use cached information. The illumos function that would refresh the cache, `resetmnttab`, is never called by libzfs. And on GNU/Linux, `getmntany` and `getmntent` don't even communicate with the kernel directly. They simply parse the file they are given, which is usually /etc/mtab or /proc/mounts. Perhaps the implementation of /proc/mounts is synchronous, ala MNT_WAIT; I don't know.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Avoid atomic_add() when updating as_lower_bound/as_upper_bound. Previous code was excessively strong on 64bit systems while not strong enough on 32bit ones. Instead introduce and use real atomic_load() and atomic_store() operations, just an assignments on 64bit machines, but using proper atomics on 32bit ones to avoid torn reads/writes. - Reduce number of buckets on large systems. Extra buckets not as much improve add speed, as hurt reads. Unlike wmsum for aggsum reads are still important.
