indexing into the PTP), not the plN_i ones (for indexing into the entire
linear page table); cf. the analogous code for amd64. Fixes ~everything
to do with kernel core dumps on i386.
This function allows the caller finer control of how the writes happen
and doesn't force stdio as interface. Optimise clear_gap a bit to not
fill the gap byte-wise. Bump minor version of libkvm.
- if the process does not exist anymore, return NULL
- if the process has created more lwps retry
XXX[1]: We should fix sysctl_kern_lwp() to return the number of lwps it
needs in oldlenp when ENOMEM. The we can avoid calling sysctl
twice (by starting let's say with always 1 lwp, or 10).
XXX[2]: We should fix kvm_getlwps to never spit errors.
- Silence new lint warnings
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.
It was only ever non-zero for zombies, and now doesn't exist.
The 'pstats' field has been valid for zombies for a while (it isn't in
the uarea any more).
Fixes part of build breakage.
know about kauth
Implemented _kvm_convertcred() to handle copying kauth_cred_t to userspace
and converting it to the appropriate 'struct eproc' members ('pcred' and
'ucred' respectively).
Okay mlelstv@.
2. Don't malloc/free procbase/procbase2/lwpbase continuously. Keep track
of the size, and only do it if necessary.
3. Write a macro to malloc/realloc and set the size of members so that it
is done correctly. Previous open coded version in kvm_file.c always
set the length, which is incorrect.
4. Remove bogus check against INT_MAX.
5. use NULL to initialize pointers instead of 0.
in deadproc according to the comment in kern_proc.c. deadproc is not a
struct proclist anymore, so it would require more work to scan anyway, and
this is unnecessary.
lookup and allocation, and any dependency on NPROC or MAXUSERS.
NO_PID changed to -1 (and renamed NO_PGID) to remove artificial limit
on PID_MAX.
As discussed on tech-kern.
symlink the appropriate machine & sparc include directories into the objdir.
XXX: this is necessary until (when?) the sparc Arch Dependent headers
(used by MACHINE_ARCH==sparc) are separated from the sparc Machine
Dependent headeres (used by MACHINE==sparc but not MACHINE==sparc64).
and in libkvm. Then teach ps how to show them to you.
Also, teach ps how to show the names for all the uids, the rest of the
group numbers, and the "group access list".
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".
- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.
- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs
* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz
* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.
* Always install /sbin/init statically (for now)
The net effect of these changes depends on how the variables are set:
1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so
2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so
3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed
kvm_getproc2() -> sysctl(KERN_PROC2)
kvm_getargv2() -> sysctl(KERN_PROC_ARGS, KERN_PROC_ARGV)
kvm_getenvv2() -> sysctl(KERN_PROC_ARGS, KERN_PROC_ENV)
Add new KVM_NO_FILES flag to kvm_open*() - set up enough state to
use the above calls without having to open any kernel files.
XXX: kvm_getprocs.3 and kvm_open.3 to be updated soon.
to pull a few #define's from the sparc64 include's into this file,
renamed so that they don't break the sparc64. this is really hacky,
and should be fixed somehow. if the sparc is going to know about
32bit sparc64 kernels, the information necessary to get this needs
to exist somewhere for it to grab, not for duplication :(
