simonb | KNF consistency: No parentheses are needed around the return value.

The way the kernel tries to prevent a userland process from allocating page
zero is hugely flawed. It is easy to demonstrate that one can trick UVM
into chosing a NULL hint after the user_va0_disable check from uvm_map.
Such a bypass allows kernel NULL pointer dereferences to be exploitable on
architectures with a shared userland<->kernel VA, like amd64.
Fix this by increasing the limit of the vm space made available for
userland processes. This way, UVM will never chose a NULL hint, since it
would be outside of the vm space.
The user_va0_disable sysctl still controls this feature.

| 05-Dec-2014 |
christos | Add compatibility for pre MIDMAGIC a.out binaries (with COMPAT_NOMID)
Oldzmagic binaries need "sysctl -w vm.user_va0_disable=0"
|
| 1.28 |
| 24-Oct-2014 |
christos | branches: 1.28.2;
remove unused prototypes
|
| 1.27 |
| 25-Jan-2014 |
christos | Clear the VM_TOPDOWN flag only when we succeed.
|
| 1.26 |
| 25-Jan-2014 |
christos | a.out binaries can't handle topdown.
Now 1.0 binaries work correctly on NetBSD-current.
|
| 1.25 |
| 23-Apr-2010 |
rmind | branches: 1.25.8; 1.25.18; 1.25.22;
Replace M_IOV and some malloc(9)s with kmem(9), and while there:
- Fix invalid free (M_TEMP vs M_IOV) in do_sys_recvmsg(), spotted by jakllsch@.
Also, same fix in osf1_sys_sendmsg_xopen().
- Fix attempt to free non-allocated memory in error path in netbsd32___getfh30().
- Plug a memory leak in compat_43_netbsd32_orecvmsg().
|
| 1.24 |
| 29-May-2008 |
mrg | branches: 1.24.12; 1.24.20; 1.24.22;
remove clause #3 from my license where there are no other
copyright holders involved.
|
| 1.23 |
| 08-Dec-2007 |
dsl | branches: 1.23.12; 1.23.14; 1.23.16; 1.23.18;
ANSIfy most of the function definitions in sys/compat (but not ndis).
All by the magic of sed ...
|
| 1.22 |
| 04-Dec-2007 |
dsl | Remove all the __P
|
| 1.21 |
| 11-Dec-2005 |
christos | branches: 1.21.44; 1.21.46; 1.21.52; 1.21.56;
merge ktrace-lwp.
|
| 1.20 |
| 26-Feb-2005 |
perry | branches: 1.20.4;
nuke trailing whitespace
|
| 1.19 |
| 20-Feb-2004 |
drochner | branches: 1.19.8; 1.19.10;
did this ever work? The EXEC_32 flag must be set _before_
exec_aout_prep_*magic(), otherwise setup_stack() fails.
|
| 1.18 |
| 20-Feb-2004 |
drochner | -MID_SPARC->NETBSD32_MID_MACHINE
-check for zero BSS size, as in kern/exec_aout.c rev. 1.23
|
| 1.17 |
| 13-Oct-2003 |
agc | Move Matt Green's code from a 4-clause to a 3-clause licence by removing
the advertising clause. Diffs provided in PR 22396 by Joel Baker, the changes
were confirmed to the board by Matt Green.
|
| 1.16 |
| 08-Aug-2003 |
christos | - GC all the setup_stack functions
- add one for linux/i386
|
| 1.15 |
| 29-Jun-2003 |
fvdl | branches: 1.15.2;
Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
|
| 1.14 |
| 28-Jun-2003 |
darrenr | Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
|
| 1.13 |
| 01-Apr-2003 |
thorpej | Use PAGE_SIZE rather than NBPG.
|
| 1.12 |
| 10-Dec-2002 |
thorpej | Rename __LDPGSZ to AOUT_LDPGSZ, to accurately reflect what it is.
|
| 1.11 |
| 10-Dec-2002 |
thorpej | Use __LDPGSZ (which must be == USRTEXT) as the text address for a.out
executables, and eliminate the USRTEXT constant, which was only used
by the a.out exec code.
|
| 1.10 |
| 05-Oct-2002 |
chs | count executable image pages as executable for vm-usage purposes.
also, always do the VTEXT vs. v_writecount mutual exclusion
(which we previously skipped if the text or data segment was empty).
|
| 1.9 |
| 27-Sep-2002 |
provos | remove trailing \n in panic(). approved perry.
|
| 1.8 |
| 13-Nov-2001 |
lukem | branches: 1.8.10;
add RCSIDs (including regeneration of files as appropriate)
|
| 1.7 |
| 30-Oct-2001 |
thorpej | - Add a new vnode flag VEXECMAP, which indicates that a vnode has
executable mappings. Stop overloading VTEXT for this purpose (VTEXT
also has another meaning).
- Rename vn_marktext() to vn_markexec(), and use it when executable
mappings of a vnode are established.
- In places where we want to set VTEXT, set it in v_flag directly, rather
than making a function call to do this (it no longer makes sense to
use a function call, since we no longer overload VTEXT with VEXECMAP's
meaning).
VEXECMAP suggested by Chuq Silvers.

| 1.6 |

mrg | branches: 1.6.4;
update copyright notices.
|
| 1.5 |

eeh | branches: 1.5.2; 1.5.4;
Support flexible process address space limits and bump kernel version number.
|
| 1.4 |
| 03-Feb-2001 |
mrg | s/sizeof(struct exec)/sizeof(struct netbsd32_exec)/ when calculating file offsets. now sunos32 nmagic/omagic work.
|
| 1.3 |
| 02-Feb-2001 |
mrg | de-static netbsd32_exec_aout_prep_[zno]magic().
de-static netbsd32_from_stat43().
move the guts of netbsd32_execve() into netbsd32_execve2().
all of are for the forthcoming sunos32 compat mode (for sparc64).
|
| 1.2 |
| 18-Dec-2000 |
mrg | copy exec_aout.c:exec_aout_setup_stack to netbsd32_exec_aout_setup_stack,
but use USRSTACK32 not USRSTACK, so that we get 32-bit stack addresses.
now 32 bit a.out binaries work on sparc64.
|
| 1.1 |
| 01-Dec-2000 |
jdolecek | branches: 1.1.2;
put a.out/elf32 specific things in netbsd32_exec_{aout|elf32}.c
emul_netbsd32 was moved to netbsd32_netbsd.c
g/c netbsd32_exec.c now

darrenr | Apply the aborted ktrace-lwp changes to a specific branch. This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it. This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.
