Remove the unused 'struct malloc_type' args to kern_malloc/realloc/free The M_xxx arg is left on the calls to malloc() and free(), maybe they could be converted to an enumeration and just saved in the malloc header (for deep diag use). Remove the malloc_type from mbuf extension. Fixes rump build as well. Welcome to 6.99.6

Remove separate mb_map. The nmbclusters is computed at boot time based on the amount of physical memory and limited by NMBCLUSTERS if present. Architectures without direct mapping also limit it based on the kmem_map size, which is used as backing store. On i386 and ARM, the maximum KVA used for mbuf clusters is limited to 64MB by default. The old default limits and limits based on GATEWAY have been removed. key_registered_sb_max is hard-wired to a value derived from 2048 clusters.

m_split0(): If the newly allocated mbuf holds only the header, don't forget to set m_len to 0. Otherwise whatever will compute the size of this chain (including s_split() itself if called again on this chain) will get it wrong, leading to various issues. Bug exposed by the NFS server code with linux clients using TCP mounts.

Dynamic sysctl. Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(), vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically. Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function. All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference. PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.

* Use a pool_cache constructor to record the physical address of mbufs in the mbuf header. * Use the new cached paddr feature of the pool_cache API to record the physical address of mbuf clusters. (We cannot use a ctor for clusters, since clusters have no constructed form; they are merely buffers). Bus_dma back-ends may use the cached physical addresses to save having to extract the physical address from virtual. * Provide space in m_ext recording the vm_page *'s for an SOSEND_LOAN_CHUNK- sized non-cluster external buffer. Use this in the sosend_loan code to save having to extract the physical address from virtual and then look up the vm_page *'s. * Provide an indication that an external buffer is mapped read-only at the MMU. Set this flag for the external buffer in the sosend_loan case, since loaned pages are always mapped read-only. Bus_dma back-ends may use this information to save cache flushing, since a cache flush of a read-only mapping is redundant on some architectures (the cache would have already been flushed when making the mapping read-only). Part 2 in a series of simple patches contributed by Wasabi Systems to improve network performance.

Changes to allow the IPv4 and IPv6 layers to align headers themseves, as necessary: * Implement a new mbuf utility routine, m_copyup(), is is like m_pullup(), except that it always prepends and copies, rather than only doing so if the desired length is larger than m->m_len. m_copyup() also allows an offset into the destination mbuf, which allows space for packet headers, in the forwarding case. * Add *_HDR_ALIGNED_P() macros for IP, IPv6, ICMP, and IGMP. These macros expand to 1 if __NO_STRICT_ALIGNMENT is defined, so that architectures which do not have strict alignment constraints don't pay for the test or visit the new align-if-needed path. * Use the new macros to check if a header needs to be aligned, or to assert that it already is, as appropriate. Note: This code is still somewhat experimental. However, the new code path won't be visited if individual device drivers continue to guarantee that packets are delivered to layer 3 already properly aligned (which are rules that are already in use).

Pool deals fairly well with physical memory shortage, but it doesn't deal with shortages of the VM maps where the backing pages are mapped (usually kmem_map). Try to deal with this: * Group all information about the backend allocator for a pool in a separate structure. The pool references this structure, rather than the individual fields. * Change the pool_init() API accordingly, and adjust all callers. * Link all pools using the same backend allocator on a list. * The backend allocator is responsible for waiting for physical memory to become available, but will still fail if it cannot callocate KVA space for the pages. If this happens, carefully drain all pools using the same backend allocator, so that some KVA space can be freed. * Change pool_reclaim() to indicate if it actually succeeded in freeing some pages, and use that information to make draining easier and more efficient. * Get rid of PR_URGENT. There was only one use of it, and it could be dealt with by the caller. From art@openbsd.org.

a whole bunch of changes to improve performance and robustness under load:
- remove special treatment of pager_map mappings in pmaps. this is
required now, since I've removed the globals that expose the address range.
pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
no longer any need to special-case it.
- eliminate struct uvm_vnode by moving its fields into struct vnode.
- rewrite the pageout path. the pager is now responsible for handling the
high-level requests instead of only getting control after a bunch of work
has already been done on its behalf. this will allow us to UBCify LFS,
which needs tighter control over its pages than other filesystems do.
writing a page to disk no longer requires making it read-only, which
allows us to write wired pages without causing all kinds of havoc.
- use a new PG_PAGEOUT flag to indicate that a page should be freed
on behalf of the pagedaemon when it's unlocked. this flag is very similar
to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
pageout fails due to eg. an indirect-block buffer being locked.
this allows us to remove the "version" field from struct vm_page,
and together with shrinking "loan_count" from 32 bits to 16,
struct vm_page is now 4 bytes smaller.
- no longer use PG_RELEASED for swap-backed pages. if the page is busy
because it's being paged out, we can't release the swap slot to be
reallocated until that write is complete, but unlike with vnodes we
don't keep a count of in-progress writes so there's no good way to
know when the write is done. instead, when we need to free a busy
swap-backed page, just sleep until we can get it busy ourselves.
- implement a fast-path for extending writes which allows us to avoid
zeroing new pages. this substantially reduces cpu usage.
- encapsulate the data used by the genfs code in a struct genfs_node,
which must be the first element of the filesystem-specific vnode data
for filesystems which use genfs_{get,put}pages().
- eliminate many of the UVM pagerops, since they aren't needed anymore
now that the pager "put" operation is a higher-level operation.
- enhance the genfs code to allow NFS to use the genfs_{get,put}pages
instead of a modified copy.
- clean up struct vnode by removing all the fields that used to be used by
the vfs_cluster.c code (which we don't use anymore with UBC).
- remove kmem_object and mb_object since they were useless.
instead of allocating pages to these objects, we now just allocate
pages with no object. such pages are mapped in the kernel until they
are freed, so we can use the mapping to find the page to free it.
this allows us to remove splvm() protection in several places.
The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

Use pool_cache_*() for mbufs and clusters. While we don't use the ctor/dtor feature, it's still faster to allocate from the cache groups than it is from the pool (cache groups are analogous to "magazines" in the Solaris SLAB allocator).

introduce m->m_pkthdr.aux to hold random data which needs to be passed between protocol handlers. ipsec socket pointers, ipsec decryption/auth information, tunnel decapsulation information are in my mind - there can be several other usage. at this moment, we use this for ipsec socket pointer passing. this will avoid reuse of m->m_pkthdr.rcvif in ipsec code. due to the change, MHLEN will be decreased by sizeof(void *) - for example, for i386, MHLEN was 100 bytes, but is now 96 bytes. we may want to increase MSIZE from 128 to 256 for some of our architectures. take caution if you use it for keeping some data item for long period of time - use extra caution on M_PREPEND() or m_adj(), as they may result in loss of m->m_pkthdr.aux pointer (and mbuf leak). this will bump kernel version. (as discussed in tech-net, tested in kame tree)

More improvements to mbuf and mbuf cluster allocation: - Initialize mbpool and mclpool with msize and mclbytes, respectively, so that those values may be patched and have an actual affect on the next system reboot. - Set low water marks on mbpool (default: 16) and mclpool (default: 8). This should be of great help for diskless systems, which need to allocate mbufs in order to clean dirty pages; the low water marks increase the chances of this being possible to do in memory starvation situations. - Add support for getting/setting some mbuf-related parameters via sysctl. * msize and mclsize (read-only) * nmbclusters (read-only unless the platform has direct-mapped pool pages, in which case the value can be increased). * mblowat and mcllowat (read/write)

Set a hard limit (rather than an advisory high water mark for pages) of NMBCLUSTERS for the mbuf cluster pool. On platforms which use direct-mapped segments for pool pages (MIPS and Alpha), this makes NMBCLUSTERS actually meaningful (such ports don't even allocate mb_map, as it is not used to map mbuf cluster pages). Improve the message logged at a maximum rate of once per second. The new message: "WARNING: mclpool limit reached; increase NMBCLUSTERS". In the back-end pool page allocator, remove the message about mb_map being full. The message was not necessarily correct as the allocator may have been starved for pages, rather than for space in the map. Also, the hard limit on the mbuf cluster pool will be reached before the map fills (the last cluster will always fit into the map), so the message is redundant. Add a comment in mbinit() about considering setting low water marks on the mbuf and mbuf cluster pools.

Update and enhancement to the mbuf code, to support use of non-cluster external storage. Highlights: - additional "void *" argument to (*ext_free)(), an opaque cookie for use by the free function. - MCLALLOC() and MCLFREE() calls are gone. They are replaced by MEXTADD() (add external storage to mbuf), MEXTMALLOC() (malloc() external storage and attach to mbuf), and MEXTREMOVE() (remove external storage from mbuf). - completely new external storage reference counting mechanism; mclrefcnt[] is gone. These changes will eventually be used to pass driver DMA buffers up the network stack, and reduce/eliminate copies in certain code paths (e.g. NFS writes). From Matt Thomas <matt@3am-software.com> and myself <thorpej@nas.nasa.gov>, with some input from Chris Demetriou <cgd@cs.cmu.edu> and review by Charles Hannum <mycroft@mit.edu>.

if kmem_malloc() fails while trying to allocate an mbuf cluster, try and free some space by calling m_reclaim(). Also, log the "mb_map full" error message (at most) every 60-seconds. The old code would log it once over the lifetime of the system, but that's not a useful diagnostic. (More useful is the new behaviour, which roughly indicates how often periods of heavy load occur, without spamming the console and system logs with messages.)
