c00254d517 * Add -D datalinktype to set the data link type to use when
capturing packets.
* Add -L to list the known data link types and exit.

bfd8b5c80d * Add support for DLT_IEEE802_11.
* When opening a live pcap, obtain the list of supported DLTs from
  the BPF.
* Add pcap_list_datalinks() to obtain a list of supported DLTs
  supported by the interface associated with the pcap descriptor.
* Add pcap_set_datalink() to set the current DLT of the pcap.
* Bump shlib 1.2 -> 1.3; new functions added.

procedures as well as commands.
This particular man page probably needs serious updating -- it is way

3f89292591 New commands:
* bssid xx:xx:xx:xx:xx:xx -- set the desired BSSID of an 802.11
  interface.
* -bssid -- unset the desired BSSID of an 802.11 interface, so
  the interface will choose automatically (default).
* channel x -- set the channel (radio frequency) of an 802.11 interface.

Current BSSID and channel are now reported in the 802.11 status
display, if supported by the interface.

Above changes from David Young <dyoung@ojctech.com>, with some slight
changes by me (use ethers(3) functions rather than hand-parsing/printing
the 802.11 address).

Document bssid/-bssid/channel, and clean up markup of parentheticals
in the manual page.

3f3ab694ad MKDYNAMICROOT=yes now the default 2002-09-22 15:09:26 +00:00
lukem
2f7d49d929 Enable MKDYNAMICROOT=yes by default.
This means that:
    +	/bin and /sbin (and the few programs in /usr/* which were statically
	linked) are now dynamically linked.
    +	The shared libraries that are needed by the /bin and /sbin programs
	are now installed into /lib (with compatability symlinks from
	/usr/lib).  These are:
		c crypt edit ipsec kvm m m387 termcap termlib util z
    +	The shared linker is now in /libexec/ld.elf_so, and
	/usr/libexec/ld.elf_so is a symlink to the former.

If you want the prior behaviour of "some applications statically linked,
the rest dynamically linked", set MKDYNAMICROOT=no in your mk.conf(5).

If you have a philosophical objection to dynamic libraries, continue
to set LDSTATIC=-static in your mk.conf(5), and please don't waste any
more time in trying to convince us why dynamic libraries are 3v1l.

94a62d45d6 add a new flag VM_MAP_DYING, which is set before we start
tearing down a vm_map.  use this to skip the pmap_update()
at the end of all the removes, which allows pmaps to optimize
pmap tear-down.  also, use the new pmap_remove_all() hook to
let the pmap implemenation know what we're up to.

f54a093e81 many improvements:
- use struct vm_page_md for attaching pv entries to struct vm_page
 - change pseg_set()'s return value to indicate whether the spare page
   was used as an L2 or L3 PTP.
 - use a pool for pv entries instead of malloc().
 - put PTPs on a list attached to the pmap so we can free them
   more efficiently (by just walking the list) in pmap_destroy().
 - use the new pmap_remove_all() interface to avoid flushing the cache and TLB
   for each pmap_remove() that's done as we are tearing down an address space.
 - in pmap_enter(), handle replacing an existing mapping more efficiently
   than just calling pmap_remove() on it.  also, skip flushing the
   TSB and TLB if there was no previous mapping, since there can't be
   anything we need to flush.  also, preload the TSB if we're pre-setting
   the mod/ref bits.
 - allocate hardware contexts like the MIPS pmap:
   allocate them all sequentially without reuse, then once we run out
   just invalidate all user TLB entries and flush the entire L1 dcache.
 - fix pmap_extract() for the case where the va is not page-aligned and
   nothing is mapped there.
 - fix calculation of TSB size.  it was comparing physmem (which is
   in units of pages) to constants that only make sense if they are
   in units of bytes.
 - avoid sleeping in pmap_enter(), instead let the caller do it.
 - use pmap_kenter_pa() instead of pmap_enter() where appropriate.
 - remove code to handle impossible cases in various functions.
 - tweak asm code to pipeline a little better.
 - remove many unnecessary spls and membars.
 - lots of code cleanup.
 - no doubt other stuff that I've forgotten.

the result of all this is that a fork+exit microbenchmark is 34% faster
and a fork+exec+exit microbenchmark is 28% faster.

adc9fb5f5b MD component of the new cpu_switch() interface. Introduces nextrunqueue(),
cpu_idle() and new cpu_switch() to replace the old cpu_switch()
which did the lot.  Runs leaner without overly blocking interrupts.

Includes cleanup of the RAS code to make use of callee-saved registers.

Benchmarks on DX4 @ 100MHz reveal a slight performance improvement
but probably not statistically signficant.  More TBD to verify this.

Changes passed a pounding on Athlon @ 1GHz too.

6a6ea308fd Separate the scheduler from the context switching code.
This is done by adding an extra argument to mi_switch() and
cpu_switch() which specifies the new process.  If NULL is passed,
then the new function chooseproc() is invoked to wait for a new
process to appear on the run queue.

Also provides an opportunity for optimisations if "switching to self".

Also added are C versions of the setrunqueue() and remrunqueue()
low-level primitives if __HAVE_MD_RUNQUEUE is not defined by MD code.

All these changes are contingent upon the __HAVE_CHOOSEPROC flag being
defined by MD code to indicate that cpu_switch() supports the changes.

ab956106b3 preliminary HP/UX notes from Giles; it needs zlib.

ad5f5e697c HP/UX fixes from Giles Lean:
- consistently support __hpux (which the HP compilers define) as well
  as __hpux__ (not sure which compilers set this, but retained anyway)
- fix a typo in the definition of signal().  arguably the codebase should
  just be converted to sigaction()...

80ee637534 - Introduce a e_fault field in struct proc to provide emulation specific
memory fault handler. IRIX uses irix_vm_fault, and all other emulation
use NULL, which means to use uvm_fault.

- While we are there, explicitely set to NULL the uninitialized fields in
struct emul: e_fault and e_sysctl on most ports

- e_fault is used by the trap handler, for now only on mips. In order to avoid
intrusive modifications in UVM, the function pointed by e_fault does not
has exactly the same protoype as uvm_fault:
int uvm_fault __P((struct vm_map *, vaddr_t, vm_fault_t, vm_prot_t));
int e_fault __P((struct proc *, vaddr_t, vm_fault_t, vm_prot_t));

- In IRIX share groups, all the VM space is shared, except one page.
This bounds us to have different VM spaces and synchronize modifications
to the VM space accross share group members. We need an IRIX specific hook
to the page fault handler in order to propagate VM space modifications
caused by page faults.
