high ping times between qemu host and gemu guest with GEMERIC.MP
hi
machines involved:
host running OpenBSD 4.1 GENERIC.MP#2 i386 / qemu-0.8.2p4 (dmesg see below)
guest running OpenBSD 4.2 GENERIC#1 i386
some running OpenBSD 4.0 GENERIC#12 i386
guest runs on host
some another machine on the same lan
1. ping guest on host

as you can see any combination but the one host <-> guest is perfectly ok.
if i use GENERIC instead of GENERIC.MP als host <-> guest works perfectly.

quick test of netbeans pkg
for testing proposes i installed a current snapshoot. i saw the announcement of the netbean pkg thus i complied jdk 1.5 and installed netbeans. when i build/run a project the output in the output/console of netbeans is mostly not readable. it prints targets like init: deps-jar: but the output form the compiler or the application looks like it prints a square for each character. looks like a font and or encoding problem? the snapshot was downloaded on the 20. march. the base system was was dated 18. march the packages 12.march (sunsite.cnlab-switch.ch).

mapping promise product name to chip-id
hi i just spend quite some time looking around to determin which disc-controller from promise is using which chipset. depending on the model your looking for you'll find someting on a mailing list. it's then up to you to believe the information found. 1. does anyone know where to find a reliable mapping table? 2. how do i have to interpret the following: in the FAQ: Supported hardware i don't see support for PDC40718. grepping the source let me assume there is. cheers llx

thanks!
wow new definition of what is a character array - i propose a change
of the c-standard :)
while it makes sense in practise it is quite confusing.
-> this should defiantly be put into the man-page!
thanks again

hi
is was playing around with a couple of attacks.
while looking at smash attacks i was supprised.
simple strcpy attack / no gcc-options (defaults)
- the stack-smash is detected in 'main'
- the stack-smash is NOT detected in 'foo'
a look at the assembler code file shows that
no code is generated in the pro-/epilog of 'foo'
gcc man did not enlighten me :( while googling
did partially:
-fstack-protector : Enable stack protection for functions which contain
character arrays.
-fno-stack-protector : Disable use of stack protection (ProPolice).
-fstack-protector-all : Enable stack protection for all functions.
-fno-stack-protector-all : Disables stack protection for all functions.
this does not yet explain the observed behavior since 'foo' contains a
character array. but it pointed me to fstack-protector-all. using this
option the smash is caught.
why only the smash in the main is detected?
i used the following example:
#include
char *src = "sehr langer string";
void foo( char * src )
{
char dst[5];
strcpy( dst, src );
}
int main(int argc, char* argv[])
{
#ifdef SMASH_MAIN
char dst[5];
strcpy( dst, src );
#else
foo( src );
#endif
return 0;
}
