christos 50e452f9f7 deal with detecting the first and last cpu differently. 2011-01-31 19:41:19 +00:00
matt c1edd37ce1 Make sure to getnlist in dovmstat 2011-01-31 18:56:04 +00:00
matt 45362e3914 Defer nlist processing until we know we need to it. If everything can be
obtained via sysctl, we can skip it entirely.  This means we can run even
if not setgid.

getuptime will now use sysctl/clock_gettime if memf is NULL.
doevcnt now sues sysctl(kern.evcnt) is memf is NULL.  It falls back to
groveling if sysctl returns an error of ENOENT.
dointr will call doevcnt to evcnt based intr stats.

christos fdbe2a0785 can't play games with structure names since cpu_data refers to cpu_info, so
provide our own copy for everything.
2010-12-25 23:36:59 +00:00
christos 5ee7c6c8d5 use a local definition of cpu_info if we have __HAVE_CPU_DATA_FIRST 2010-12-25 20:50:36 +00:00
christos 8ac898131d Don't crash on old kernels that don't have the new per cpu counters. 2010-12-25 14:18:37 +00:00
enami d5a41b7133 We still need to update ouvmexp to output the differene from
previous iteration.

christos 301830e51c make this work with the per-cpu counters. 2010-12-20 04:25:03 +00:00
christos 710d230a43 simplify and modernize:
- make sysctl mibs static
- use warn/warnx for warnings
makes binary 4K smaller.

pooka 062d6d1f8d Make "i" unsigned to mirror change to struct uvm_history 2010-07-07 11:42:18 +00:00
he d399695a05 Follow christos' suggestions, and make ks_active a u_short, and
also only use 16 u_shorts instead of 32 ints.  Also add panic()
calls for under- and overflow of the ks_active members under
DIAGNOSTIC.  The MAXBUCKET constant ended up in sys/mallocvar.h
and not sys/param.h, as the latter caused build problems.

Ride the kernel revision bump of my previous change.
2010-04-05 08:03:41 +00:00
he bb89b7208d Extend struct malloc_type to count the number of active allocations
per size, and make vmstat report this information under the "Memory
statistics by type" display, which is only printed when the kernel
has been compiled with KMEMSTATS defined, like this:

Memory statistics by type                                Type  Kern
           Type InUse  MemUse HighUse   Limit   Requests Limit Limit Size(s)
          wapbl    15   4192K   4192K  78644K     376426     0     0 32:0,256:3,512:6,131072:1,262144:2,524288:3

Since struct malloc_type is user-visible and is changed, bump kernel
revision to 5.99.26.

While it is true that malloc(9) is in general on the path of slowly
being replaced by kmem(9) (kmem_alloc/kmem_free), there remains a
lot of points of usage of malloc/free, and this could aid in finding
any leaks.  (It helped finding the leak fixed in PR#42661.)

This was discussed with and somewhat hestitantly OKed by rmind@

wiz 467a0fa1ae Bump date for uarea swap-out removal. 2009-10-21 22:18:37 +00:00
rmind 40cf6f3659 Remove uarea swap-out functionality:
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code.  Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

Discussed on <tech-kern>, reviewed by <ad>.

matt 5331076d97 NFS hash tables no longer exist. 2008-10-22 11:36:58 +00:00
he cef17755f2 Restore the "pages actige" and "pages inactive" value printouts
in "vmstat -s" output when run on the active kernel.

The reason we can't easily provide these values out of a crash
dump, is that these fields are no longer proper members of
struct uvmexp, but rather are estimated by and dependent on
the currently active page replacement policy in the kernel.

ad ea3f10f7e0 Merge more changes from vmlocking2, mainly:
- Locking improvements.
- Use pool_cache for more items.
2007-12-26 16:01:34 +00:00
ad 73157b0e11 - Support two different sizes of pool_cache group. The default has 14 or 15
items, and the new large groups (for busy caches) have 62 or 63 items.
- Add PR_LARGECACHE flag as a hint that a pool_cache should use large groups.
  This should be eventually be tuned at runtime.
- Report group size for vmstat -C.

tls 4147a3c54a Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry.  RedHat has
evidently built all "core system packages" with this option for some time.

This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.

This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros.  Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.

Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default.  Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.
