be used alongside -D, but as this was not documented I thought it was a bug
and "fixed" -e's behavior locally (so I got the correct output before, but
nobody else).
Also, fix a race condition that could cause the SSH server to not be killed
if the pid file was not written before the kill, which might happen on very
fast machines. There still may be a problem when trying to do the connection
if the server has not yet finished initialization...
global int machine_has_rtas that can be used to decide if a machine has
rtas functionality or not. Take a crack at power off support for the
pegasos, which doesn't work right, probably due to a firmware bug.
This patch dates (mostly) back to 2002; the critical parts of it were
handled back then by security-officer. As far as I know, there's
nothing exploitable fixed herein.
A slightly earlier version of this patch was reviewed by Christian Biere
when I filed it as PR 34750.
idea why this makes it work, but apparently it needs to return status,
and if it doesn't, it won't reboot. (unless you call it at the askroot
prompt, then it worked fine). *boggle*.
L2 and L3 cache initialization. Mostly to get the L2 enabled on the
pegasos, but since I had the manual, I fixed a few other things I saw
while I was there.
For regular (non PIE) executables randomization is enabled for:
1. The data segment
2. The stack
For PIE executables(*) randomization is enabled for:
1. The program itself
2. All shared libraries
3. The data segment
4. The stack
(*) To generate a PIE executable:
- compile everything with -fPIC
- link with -shared-libgcc -Wl,-pie
This feature is experimental, and might change. To use selectively add
options PAX_ASLR=0
in your kernel.
Currently we are using 12 bits for the stack, program, and data segment and
16 or 24 bits for mmap, depending on __LP64__.
for PT_PHDR headers when the program has been loader to a vaddr other than
then one specified (a randomized one), and modifying the relocation base
address appropriately (idea from elad)
