Commit 6d667106 is incomplete and misses non-r4k CPUs. This patch reverts the commit and fixes in other way. o Do FCSR checking in caller of restore_fp_context. o Send SIGFPE if the signal handler set any FPU exception bits.

access_ok in compat-signal.h is wrong (checking destination instead of source) and redundant (already checked before calling this function). Also sf_mask in struct sigframe32 should be compat_sigset_t type. Signed-off-by: NAtsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>

This macro was used to save static registers before calling sys_sigsuspend() and sys_sigreturn(). For the sys_sigreturn() case, there's no point to save them since they have been already saved by setup_sigcontext() before calling the signal handler. For the sys_sigsuspend() case, I don't see any reasons... Signed-off-by: NFranck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: NRalf Baechle <ralf@linux-mips.org>

All the information in the MIPS c0_status register is priviledged. Nothing that would constitute part of the thread context. The one flag one could possibly argument about might be c0_status.fr but none of the ABIs or tools or application software can make use of it. So for consistency with restore_sigcontext32(), which does not restore c0_status register, this patch remove the saving part.

This patch makes 'struct sigframe' declaration avalaible for all signals code. It allows signal32 to not have its own declaration. This patch also removes all ICACHE_REFILLS_WORKAROUND_WAR tests in structure declaration and hopefully make them more readable.

In entry.S resume_userspace ... jal do_notify_resume form a loop through which the kernel will iterate as long as work is pending. If we iterate through this loop more than once with no signal pending for at least one but the last iteration we will take do the syscall restarting multiple times resulting in a syscall return prior to the the syscall instruction in userspace. This may happen when debugging a multithreaded program. Debugging and original fix by Maciej; extended to other ABIs by me. Signed-off-by: NMaciej W.

It has been reported that the way Linux handles NODEFER for signals is not consistent with the way other Unix boxes handle it. 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.
