On three of the several paths in entry_64.S that call do_notify_resume() on the way back to user mode, we fail to properly check again for newly-arrived work that requires another call to do_notify_resume() before going to user mode. These paths set the mask to check only _TIF_NEED_RESCHED, but this is wrong. The other paths that lead to do_notify_resume() do this correctly already, and entry_32.S does it correctly in all cases. All paths back to user mode have to check all the _TIF_WORK_MASK flags at the last possible stage, with interrupts disabled. Otherwise, we miss any flags (TIF_SIGPENDING for example) that were set any time after we entered do_notify_resume(). More work flags can be set (or left set) synchronously inside do_notify_resume(), as TIF_SIGPENDING can be, or asynchronously by interrupts or other CPUs (which then send an asynchronous interrupt). There are many different scenarios that could hit this bug, most of them races. The simplest one to demonstrate does not require any race: when one signal has done handler setup at the check before returning from a syscall, and there is another signal pending that should be handled. The second signal's handler should interrupt the first signal handler before it actually starts (so the interrupted PC is still at the handler's entry point). Instead, it runs away until the next kernel entry (next syscall, tick, etc). This test behaves correctly on 32-bit kernels, and fails on 64-bit (either 32-bit or 64-bit test binary). With this fix, it works. #define _GNU_SOURCE #include <stdio.h> #include <signal.h> #include <string.h> #include <sys/ucontext.h> #ifndef REG_RIP #define REG_RIP REG_EIP #endif static sig_atomic_t hit1, hit2; static void handler (int sig, siginfo_t *info, void *ctx) { ucontext_t *uc = ctx; if ((void *) uc->uc_mcontext.gregs[REG_RIP] == &handler) { if (sig == SIGUSR1) hit1 = 1; else hit2 = 1; } printf ("%s at %#lx\n", strsignal (sig), uc->uc_mcontext.gregs[REG_RIP]); } int main (void) { struct sigaction sa; sigset_t set; sigemptyset (&sa.sa_mask); sa.sa_flags = SA_SIGINFO; sa.sa_sigaction = &handler; if (sigaction (SIGUSR1, &sa, NULL) || sigaction (SIGUSR2, &sa, NULL)) return 2; sigemptyset (&set); sigaddset (&set, SIGUSR1); sigaddset (&set, SIGUSR2); if (sigprocmask (SIG_BLOCK, &set, NULL)) return 3; printf ("main at %p, handler at %p\n", &main, &handler); raise (SIGUSR1); raise (SIGUSR2); if (sigprocmask (SIG_UNBLOCK, &set, NULL)) return 4; if (hit1 + hit2 == 1) { puts ("PASS"); return 0; } puts ("FAIL"); return 1; } Signed-off-by: Roland McGrath <roland@redhat.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

In the course of the recent unification of the NMI watchdog an assignment to timer_ack to switch off unnecesary POLL commands to the 8259A in the case of a watchdog failure has been accidentally removed. The statement used to be limited to the 32-bit variation as since the rewrite of the timer code it has been relevant for the 82489DX only. This change brings it back. Signed-off-by: Maciej W.

There is no such entity as ISA IRQ2. The ACPI spec does not make it explicitly clear, but does not preclude it either -- all it says is ISA legacy interrupts are identity mapped by default (subject to overrides), but it does not state whether IRQ2 exists or not. As a result if there is no IRQ0 override, then IRQ2 is normally initialised as an ISA interrupt, which implies an edge-triggered line, which is unmasked by default as this is what we do for edge-triggered I/O APIC interrupts so as not to miss an edge. To the best of my knowledge it is useless, as IRQ2 has not been in use since the PC/AT as back then it was taken by the 8259A cascade interrupt to the slave, with the line position in the slot rerouted to newly-created IRQ9. No device could thus make use of this line with the pair of 8259A chips. Now in theory INTIN2 of the I/O APIC may be usable, but the interrupt of the device wired to it would not be available in the PIC mode at all, so I seriously doubt if anybody decided to reuse it for a regular device. However there are two common uses of INTIN2. One is for IRQ0, with an ACPI interrupt override (or its equivalent in the MP table). But in this case IRQ2 is gone entirely with INTIN0 left vacant. The other one is for an 8959A ExtINTA cascade. In this case IRQ0 goes to INTIN0 and if ACPI is used INTIN2 is assumed to be IRQ2 (there is no override and ACPI has no way to report ExtINTA interrupts). This is where a problem happens. The problem is INTIN2 is configured as a native APIC interrupt, with a vector assigned and the mask cleared. And the line may indeed get active and inject interrupts if the master 8959A has its timer interrupt enabled (it might happen for other interrupts too, but they are normally masked in the process of rerouting them to the I/O APIC). There are two cases where it will happen: * When the I/O APIC NMI watchdog is enabled. This is actually a misnomer as the watchdog pulses are delivered through the 8259A to the LINT0 inputs of all the local APICs in the system. The implication is the output of the master 8259A goes high and low repeatedly, signalling interrupts to INTIN2 which is enabled too! [The origin of the name is I think for a brief period during the development we had a capability in our code to configure the watchdog to use an I/O APIC input; that would be INTIN2 in this scenario.] * When the native route of IRQ0 via INTIN0 fails for whatever reason -- as it happens with the system considered here. In this scenario the timer pulse is delivered through the 8259A to LINT0 input of the local APIC of the bootstrap processor, quite similarly to how is done for the watchdog described above. The result is, again, INTIN2 receives these pulses too. Rafael's system used to escape this scenario, because an incorrect IRQ0 override would occupy INTIN2 and prevent it from being unmasked. My conclusion is IRQ2 should be excluded from configuration in all the cases and the current exception for ACPI systems should be lifted. The reason being the exception not only being useless, but harmful as well. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Cc: "Rafael J.

Unlike the 32-bit one, the 64-bit variation of the LVT0 setup code for the "8259A Virtual Wire" through the local APIC timer configuration does not fully configure the relevant irq_chip structure. Instead it relies on the preceding I/O APIC code to have set it up, which does not happen if the I/O APIC variants have not been tried. The patch includes corresponding changes to the 32-bit variation too which make them both the same, barring a small syntactic difference involving sequence of functions in the source. That should work as an aid with the upcoming merge. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Cc: "Rafael J.

IRQ0 is edge-triggered, but the "8259A Virtual Wire" through the local APIC configuration in the 32-bit version uses the "fasteoi" handler suitable for level-triggered APIC interrupt. Rewrite code so that the "edge" handler is used. The 64-bit version uses different code and is unaffected. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Cc: "Rafael J.

In dwarf2_32.h, test for CONFIG_AS_CFI instead of CONFIG_UNWIND_INFO. Turns out that searching for UNWIND_INFO returns no match in any Kconfig or Makefile, so we're really just throwing everything away regarding dwarf frames for i386. The test that generates CONFIG_AS_CFI does not have anything x86_64-specific, and right now, checking V=1 builds shows me that the flags is there anyway, although unused.

When we release the iclog, we do an atomic_dec_and_lock to determine if we are the last reference and need to trigger update of log headers and writeout. However, in xlog_state_get_iclog_space() we also need to check if we have the last reference count there. If we do, we release the log buffer, otherwise we decrement the reference count. But the compare and decrement in xlog_state_get_iclog_space() is not atomic, so both places can see a reference count of 2 and neither will release the iclog. That leads to a filesystem hang. Close the race by replacing the atomic_read() and atomic_dec() pair with atomic_add_unless() to ensure that they are executed atomically.

But regarding segment operands there's a subtle detail in the x86 instruction set: the above 16-bit moves are zero-extend, but only if it goes to a register. If it goes to a memory operand, -0x34(%rbp) in the above case, there's no zero-extend to 32-bit and the instruction will only save 16 bits instead of the intended 32-bit. The other 16 bits is random data - which can cause problems when that value is used later on. The solution is to only allow segment operands to go to registers. This fix allows my test-system to boot up without crashing. Signed-off-by: Ingo Molnar <mingo@elte.hu>

Some BIOSen enable DIPM via _GTF which causes command timeouts under certain configuration. This didn't occur on 2.6.25 because 2.6.25 defaulted to SRST, so _GTF wasn't executed during boot probe, so ahci host reset disabled DIPM and as _GTF wasn't executed after SRST, DIPM wasn't enabled. On 2.6.26, hardreset is used during probe and after probe _GTF is executed enabling DIPM and thus the failures. This patch could theoretically disable DIPM on machines which used to have it enabled on 2.6.25 but AFAIK ahci is currently the only driver which uses SATA ACPI hierarchy (_SDD) and as the host reset would have always disabled DIPM, this shouldn't happen.
