christos | Get rid of usrstack/USRSTACK. Document that the old version of getargv is
broken because of ASLR.
|
| 1.31 |
| 25-Apr-2020 |
maxv | Switch to the new PTE naming. The old naming is now unused, remove it.
|
| 1.30 |
| 19-Feb-2014 |
dsl | Remove the #include <sys/user.h> from all of libkvm.
sys/user.h is a stub that just #includes sys/pcb.h.
There are no 'struct pcb' anywhere in here, so I'm extremely doubtful
any of the builds will fail.
OTOH it might be relying on a header that pcb.h includes.
In any case i386 and amd64 build.

jym | branches: 1.29.6; 1.29.12;
Import PAE support for kvm(3):
- add kvm_i386pae.c (used for PAE memory translations), and update Makefile
for libkvm build.
- in pdppaddr: pass a flag to indicate PAE mode. Use a bit ignored
by the MMU. Mask address with PG_FRAME to avoid side effects.
Tested with vmstat(1)/netstat(1) to debug core files of PAE and !PAE
kernels. Older kernel dumps will default to native i386 (!PAE) mode.
XXX Currently, savecore(8) will fail to dump a PAE kernel in a !PAE
environment (and reciprocally). So you need to sync and reboot
with a kernel of the same mode as the one that crashed. Once the dump
is successful, this does not matter anymore.

jym | Change kvm_pa2off() and kvm_kvatop() prototypes (private to kvm(3)):
-int _kvm_kvatop(kvm_t *, u_long, u_long *);
-off_t _kvm_pa2off(kvm_t *, u_long);
+int _kvm_kvatop(kvm_t *, vaddr_t, paddr_t *);
+off_t _kvm_pa2off(kvm_t *, paddr_t);
Basically, use vaddr_t for VA and paddr_t for PA. In addition, for variables
representing addresses, use paddr_t or vaddr_t, depending on the context.
For most arches, vaddr_t and paddr_t are equivalent to unsigned long. However,
the change was needed for exotic situations, like i386 PAE, were unsigned long
is not suitable for PA which are 64 bits long. As this required a complete
change of the function prototypes, all arches had to be adapted accordingly.
Core files from before this commit should still work with the new code; I did
not see any direct dependency between core's structure and kvatop/pa2off.
The change was compile tested for all arches, as it impacts all of them.

jym | Ansify and KNF all functions within kvm(3). No objection on current-users@.
Used as ground for u_long => vaddr_t/paddr_t replacements in kvm(3)
private functions.
Compile tested for all arches. See also:

| 05-Jan-2008 |
jld | Add address translation support for 4MB pages, which we use to map the
kernel text.
|
| 1.23 |
| 05-Jan-2008 |
jld | The address translation routine needs to use the plN_pi macros (for
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.
