INIT_THREAD enables interrupts in the thread_struct's saved flags. This means that interrupts get enabled in the middle of context_switch() while switching to new tasks that get forked off the init task during boot. Don't do this.

Al Viro noted that CRIS fails to handle multiple signals. This fixes the problem for CRISv32 by making it use a C work_pending handling loop similar to the ARM implementation in 0a267fa6 ("ARM: 7472/1: pull all work_pending logics into C function"). This also happens to fixes the warnings which currently trigger on CRISv32 due to do_signal() being called with interrupts disabled. Test case (should die of the SIGSEGV which gets raised when setting up the stack for SIGALRM, but instead reaches and executes the _exit(1)): #include <unistd.h> #include <signal.h> #include <sys/time.h> #include <err.h> static void handler(int sig) { } int main(int argc, char *argv[]) { int ret; struct itimerval t1 = { .it_value = {1} }; stack_t ss = { .ss_sp = NULL, .ss_size = SIGSTKSZ, }; struct sigaction action = { .sa_handler = handler, .sa_flags = SA_ONSTACK, }; ret = sigaltstack(&ss, NULL); if (ret < 0) err(1, "sigaltstack"); sigaction(SIGALRM, &action, NULL); setitimer(ITIMER_REAL, &t1, NULL); pause(); _exit(1); return 0; } Reported-by:

Al Viro noted that CRIS is vulnerable to bogus restarts on sigreturn. The fixes CRISv32 by using regs->exs as an additional indicator to whether we should attempt to restart the syscall or not. EXS is only used in the sigtrap handling, and in that path we already have r9 (the other indicator, which indicates if we're in a syscall or not) cleared. Test case, a port of Al's ARM version from 653d48b2 ("arm: fix really nasty sigreturn bug"): #include <unistd.h> #include <signal.h> #include <stdlib.h> #include <sys/time.h> #include <errno.h> void f(int n) { register int r10 asm ("r10") = n; __asm__ __volatile__( "ba 1f \n" "nop \n" "break 8 \n" "1: ba . \n" "nop \n" : : "r" (r10) : "memory"); } void handler1(int sig) { } void handler2(int sig) { raise(1); } void handler3(int sig) { exit(0); } int main(int argc, char *argv[]) { struct sigaction s = {.sa_handler = handler2}; struct itimerval t1 = { .it_value = {1} }; struct itimerval t2 = { .it_value = {2} }; signal(1, handler1); sigemptyset(&s.sa_mask); sigaddset(&s.sa_mask, 1); sigaction(SIGALRM, &s, NULL); signal(SIGVTALRM, handler3); setitimer(ITIMER_REAL, &t1, NULL); setitimer(ITIMER_VIRTUAL, &t2, NULL); f(-513); /* -ERESTARTNOINTR */ return 0; } Reported-by:

r9 is used to determine whether syscall restarting must be performed or not. Unfortunately, r9 is never set to zero in the non-syscall path, and r9 is on top of that a callee-saved register which can be set to non-zero by the C functions that are called during IRQ handling. This means that if r10 (used for the syscall return value) is one of the -ERESTART* values when a hardware interrupt occurs which leads to a signal being delivered to the process, the kernel will "restart" a syscall which never occurred. This will lead to the PC being moved back by 2 on return to user space. Fix the problem by setting r9 to zero in the interrupt path. Test case (should loop forever but ends up executing the break 8 trap instruction): #include <signal.h> #include <stdlib.h> #include <sys/time.h> void f(int n) { register int r9 asm ("r9") = 1; register int r10 asm ("r10") = n; __asm__ __volatile__( "ba 1f \n" "nop \n" "break 8 \n" "1: ba . \n" "nop \n" : : "r" (r9), "r" (r10) : "memory"); } void handler1(int sig) { } int main(int argc, char *argv[]) { struct itimerval t1 = { .it_value = {1} }; signal(SIGALRM, handler1); setitimer(ITIMER_REAL, &t1, NULL); f(-513); /* -ERESTARTNOINTR */ return 0; } Signed-off-by:

Firstly, handle zero length calls properly. Believe it or not there are a few of these happening during early boot. Next, we can't just drop to a memcpy() call in the forward copy case where dst <= src. The reason is that the cache initializing stores used in the Niagara memcpy() implementations can end up clearing out cache lines before we've sourced their original contents completely. For example, considering NG4memcpy, the main unrolled loop begins like this: load src + 0x00 load src + 0x08 load src + 0x10 load src + 0x18 load src + 0x20 store dst + 0x00 Assume dst is 64 byte aligned and let's say that dst is src - 8 for this memcpy() call. That store at the end there is the one to the first line in the cache line, thus clearing the whole line, which thus clobbers "src + 0x28" before it even gets loaded. To avoid this, just fall through to a simple copy only mildly optimized for the case where src and dst are 8 byte aligned and the length is a multiple of 8 as well. We could get fancy and call GENmemcpy() but this is good enough for how this thing is actually used. Reported-by:

When the device is powered up, some (older) firmware versions fail to work properly if we send commands before the boot is complete (everything is OK when the device is hot-plugged). The firmware indicates its ready status by putting the link up. Newer firmwares delay the first command so they don't suffer from this problem. They also report the link being always up. Wait for firmware to become ready (link up) before sending any commands and/or data. This also allows lowering CMD_TIMEOUT value to a reasonable time. Tested with 4.1.0.9 (old) and 4.1.0.30 (new) firmware versions. Signed-off-by:
