- 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".
