Yep, apply http://linux.bkbits.net:8080/linux-2.5/diffs/include/asm-i386/[email protected]?nav=index.html| src/.|src/include|src/include/asm-i386|hist/include/asm-i386/i387.h and it should be safe. For 2.4-wolk, 4.10s is the oldest I have flying around on some machines: root@christian:[/] # uname -a Linux christian 2.4.20-wolk4.10s #1 Mon Feb 2 14:51:50 CET 2004 i686 GNU/Linux root@christian:[/] # ./crash ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ............................................................................... ........................................................................*...... ................................*Floating point exception root@christian:[/] # So as you see (or not ;) this bug is known since I don't know when (very long) and fixed several months ago by me in 2.4-wolk. I forgot to merge that fix into 2.6-wolk though :( Another thing why mainline kernels are bullshit concerning security. I am curious if a 2.4.26 mainline + grsec 1.9.15 or 2.0 is still crashable. If it is, aehm, I stop this sentence.
