* ARM: CPU hotplug: ensure correct ordering of unplugRussell King2010-12-201-1/+3
| | | | | | | | Don't call idle_task_exit() with interrupts disabled, and ensure that we have a memory barrier after interrupts are disabled but before signalling that this CPU has shut down. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: CPU hotplug: remove bug checks in platform_cpu_die()Russell King2010-12-205-48/+0
| | | | | | | | | platform_cpu_die() is entered from the CPU's own idle thread, which can not be migrated to other CPUs. Moreover, the 'cpu' argument comes from the thread info, which will always be the 'current' CPU. So remove this useless bug check. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: CPU hotplug: move cpu_killed completion to core codeRussell King2010-12-206-35/+19
| | | | | | | | | We always need to wait for the dying CPU to reach a safe state before taking it down, irrespective of the requirements of the platform. Move the completion code into the ARM SMP hotplug code rather than having each platform re-implement this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: SMP: consolidate trace_hardirqs_off() into common SMP codeRussell King2010-12-207-12/+1
| | | | | | | | All platforms call trace_hardirqs_off() in their secondary startup code, so move this into the core SMP code - it doesn't need to be in the per-platform code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: SMP: consolidate the common parts of smp_prepare_cpus()Russell King2010-12-208-169/+83
| | | | | | | | | There is a certain amount of smp_prepare_cpus() which doesn't belong in the platform support code - that is, code which is invariant to the SMP implementation. Move this code into arch/arm/kernel/smp.c, and add a platform_ prefix to the original function. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: SMP: get rid of references to poke_milo and MiloRussell King2010-12-202-39/+12
| | | | | | | | Milo is an old boot loader, which is no longer relevant for these platforms. References to it are misleading. Move the code out of poke_milo(), and remove references to milo in comments. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* ARM: SMP: Clean up ncores sanity checksRussell King2010-12-206-33/+6
| | | | | | | | | | scu_get_core_count() never returns zero cores, so we don't need to check and correct if ncores is zero. Tegra was missing the check against NR_CPUS, leading to a potential bitfield overflow if this becomes the case. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: SMP: move CPU number sanity checks to smp_init_cpus()Russell King2010-12-203-33/+34

* ARM: SMP: use more sane register allocation for __fixup_smp_on_upRussell King2010-12-201-17/+22

* ARM: SMP: remove IRQ-disabling for smp_cross_call()Russell King2010-12-031-6/+0
| | | | | | | | | | | As we've now removed the spinlock and bitmask, we have nothing left which requires interrupts to be disabled when sending an IPI. All current IPI-sending implementations use the GIC, which also does not require interrupts disabled when calling gic_raise_softirq(). Remove the now unnecessary IRQ disable.

* | exec: copy-and-paste the fixes into compat_do_execve() pathsOleg Nesterov2010-11-303-17/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Note: this patch targets 2.6.37 and tries to be as simple as possible. That is why it adds more copy-and-paste horror into fs/compat.c and uglifies fs/exec.c, this will be cleanuped later. compat_copy_strings() plays with bprm->vma/mm directly and thus has two problems: it lacks the RLIMIT_STACK check and argv/envp memory is not visible to oom killer. Export acct_arg_size() and get_arg_page(), change compat_copy_strings() to use get_arg_page(), change compat_do_execve() to do acct_arg_size(0) as do_execve() does. Add the fatal_signal_pending/cond_resched checks into compat_count() and compat_copy_strings(), this matches the code in fs/exec.c and certainly makes sense.

* | exec: make argv/envp memory visible to oom-killerOleg Nesterov2010-11-302-2/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Brad Spengler published a local memory-allocation DoS that evades the OOM-killer (though not the virtual memory RLIMIT): http://www.grsecurity.net/~spender/64bit_dos.c execve()->copy_strings() can allocate a lot of memory, but this is not visible to oom-killer, nobody can see the nascent bprm->mm and take it into account. With this patch get_arg_page() increments current's MM_ANONPAGES counter every time we allocate the new page for argv/envp. When do_execve() succeds or fails, we change this counter back. Technically this is not 100% correct, we can't know if the new page is swapped out and turn MM_ANONPAGES into MM_SWAPENTS, but I don't think this really matters and everything becomes correct once exec changes ->mm or fails.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit e0fdace10e75dac67d906213b780ff1b1a4cc360. On-list discussion seems to suggest that the robustness fixes for printk make this unnecessary and DaveM has also agreed in person at Kernel Summit and on list. The main problem with this code is once we hit a lockdep splat we always keep oops_in_progress set, the console layer uses oops_in_progress with KMS to decide when it should be showing the oops and not showing X, so it causes problems around suspend/resume time when a userspace resume can cause a console switch away from X, only if oops_in_progress is set (which is what we want if an oops actually is in progress, but not because we had a lockdep splat 2 days prior).

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Lenovos have TPMs that require a quirk to function correctly. This can be autodetected by checking whether the device has a _HID of INTC0102. This is an invalid PNPid, and as such is discarded by the pnp layer - however it's still present in the ACPI code, so we can pull it out that way. This means that the quirk won't be automatically applied on non-ACPI systems, but without ACPI we don't have any way to identify the chip anyway so I don't think that's a great concern.

Other limits might be needed as well (if we queue other types of files), since the passfd mechanism is currently limited by socket receive queue sizes only. Add a recursion_level to unix socket, allowing up to 4 levels. Each time we send an unix socket through sendfd mechanism, we copy its recursion level (plus one) to receiver.

According to errata draft QE_GENERAL-A003(High Tx Virtual FIFO threshold size can cause UCC to halt), setting UTFTT less than [(UTFS x (M - 8)/M) - 128] will prevent this from happening (M is the minimum buffer size).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | inet sockets corresponding to passive connections are added to the bind hash using ___inet_inherit_port(). These sockets are later removed from the bind hash using __inet_put_port(). These two functions are not exactly symmetrical. __inet_put_port() decrements hashinfo->bsockets and tb->num_owners, whereas ___inet_inherit_port() does not increment them. This results in both of these going to -ve values. This patch fixes this by calling inet_bind_hash() from ___inet_inherit_port(), which does the right thing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | We were truncating the number of unicast and multicast MAC addresses supported. Additionally, we were incorrectly computing the MAC Address hash (a "1 << N" where we needed a "1ULL << N"). Signed-off-by: Casey Leedom <leedom@chelsio.com> Signed-off-by: David S.
