* [PATCH] m68knommu: fix a5 reg corruption in signal handlersGreg Ungerer2006-01-101-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a patch adapted from a posting by Andrea Tarani which was pointed out to me by Bernardo Innocenti. Thanks to both of them for their help and patience. The original posting is here: http://mailman.uclinux.org/pipermail/uclinux-dev/2005-July/033543.html The problem first manifest itself as busybox ping terminating with an "Illegal instruction". I reduced this to a test case and found that variable size arrays allocated on the stack could lead to stacks not aligned on 32 bit boundaries. For the Coldfire this proved fatal. Having been pointed out this patch by Bernardo, I applied it and it fixed the first test case. I then went back to busybox's ping. This still failed with "Illegal instruction", but in a different way. Before it depended on the size allocated for the ping buffer, now it happened every time. I also found it depended on optimisation level (gcc-3.4.0) -Os was okay but not -O2. After a lot of looking, it turned out that register a5 was being corrupted by the signal handler (after applying the patch). I re-worked the patch a bit to save/restore a5 and now all seems well.

* [PATCH] consolidate sys_ptrace()Christoph Hellwig2005-11-071-38/+1
| | | | | | | | | | | | | | | | | | | | | | The sys_ptrace boilerplate code (everything outside the big switch statement for the arch-specific requests) is shared by most architectures. This patch moves it to kernel/ptrace.c and leaves the arch-specific code as arch_ptrace. Some architectures have a too different ptrace so we have to exclude them. They continue to keep their implementations. For sh64 I had to add a sh64_ptrace wrapper because it does some initialization on the first call. For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.

* | [PATCH] convert signal handling of NODEFER to act like other Unix boxes.Steven Rostedt2005-08-291-6/+5

I've written a program to test the behavior of how this flag affects signals and had several reports from people who ran this on various Unix boxes, confirming that Linux seems to be unique on the way this is handled. The way NODEFER affects signals on other Unix boxes is as follows: 1) If NODEFER is set, other signals in sa_mask are still blocked. 2) If NODEFER is set and the signal is in sa_mask, then the signal is still blocked. (Note: this is the behavior of all tested but Linux _and_ NetBSD 2.0 *). The way NODEFER affects signals on Linux: 1) If NODEFER is set, other signals are _not_ blocked regardless of sa_mask (Even NetBSD doesn't do this). 2) If NODEFER is set and the signal is in sa_mask, then the signal being handled is not blocked. The patch converts signal handling in all current Linux architectures to the way most Unix boxes work. Unix boxes that were tested: DU4, AIX 5.2, Irix 6.5, NetBSD 2.0, SFU 3.5 on WinXP, AIX 5.3, Mac OSX, and of course Linux 2.6.13-rcX. * NetBSD was the only other Unix to behave like Linux on point #2. The main concern was brought up by point #1 which even NetBSD isn't like Linux. So with this patch, we leave NetBSD as the lonely one that behaves differently here with #2.
