[PATCH] uml: fix TT mode by reverting "use fork instead of clone"

2005-07-15T21:15:26Z

From: Jeff Dike , Paolo 'Blaisorblade' Giarrusso Revert the following patch, because of miscompilation problems in different environments leading to UML not working *at all* in TT mode; it was merged lately in 2.6 development cycle, a little after being written, and has caused problems to lots of people; I know it's a bit too long, but it shouldn't have been merged in first place, so I still apply for inclusion in the -stable tree. Anyone using this feature currently is either using some older kernel (some reports even used 2.6.12-rc4-mm2) or using this patch, as included in my -bs patchset. For now there's not yet a fix for this patch, so for now the best thing is to drop it (which was widely reported to give a working kernel). "Convert the boot-time host ptrace testing from clone to fork. They were essentially doing fork anyway. This cleans up the code a bit, and makes valgrind a bit happier about grinding it."

[PATCH] uml: fix strace -f

2005-06-08T23:21:12Z

It turns out that we need to check for pending signals when a newly forked process is run for the first time. With strace -f, strace needs to know about the forked process before it gets going. If it doesn't, then it ptraces some bogus values into its registers, and the process segfaults. So, I added calls to interrupt_end, which does that, plus checks for reschedules. There shouldn't be any of those, but x86 does the same thing, so I'm copying that behavior to be safe.

[PATCH] uml: remove jail mode + other leftovers

2005-05-28T23:46:14Z

This var is currently useless, as it's apparent from reading the code. Until 2.6.11 it was used in some code related to jail mode, in the same proc.: if(jail){ while(!reading) sched_yield(); } jail mode has been dropped, together with that use, so let's finish dropping this. Also, remove some other useless definitions I met. Acked-by: Jeff Dike Signed-off-by: Paolo 'Blaisorblade' Giarrusso Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] uml: stack dump fix

[PATCH] uml: fix segfault on exit with CONFIG_GCOV

2005-05-28T23:46:12Z

We need to disable signals on exit in all cases, not just when rebooting. Signed-off-by: Jeff Dike Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] uml: remove 2_5compat.h

2005-05-28T23:46:11Z

Remove old useless header that was used in Ye Olde Times during 2.4->2.5 porting to abstract differences. It's definitions are no more used anyway, so let's finally kill it.

[PATCH] uml: turn off kmalloc always on a fatal signal
