From cf1c4a094f46ace5bf00078e2db73491ddf018fe Mon Sep 17 00:00:00 2001 From: Josh Hunt Date: Tue, 19 Feb 2013 11:35:59 -0800 Subject: netfilter: ipset: timeout values corrupted on set resize If a resize is triggered on a set with timeouts enabled, the timeout values will get corrupted when copying them to the new set. This occured b/c the wrong timeout value is supplied to type_pf_elem_tadd(). This also adds simple debug statement similar to the one in type_pf_resize().

This workaround was necessary because some archs may call irq_exit() with irqs enabled and there is still some code in the end of this function that is not covered by the HARDIRQ_OFFSET but want to stay non-preemptible. Now that irq are always disabled in irq_exit(), the whole code is guaranteed not to be preempted. We can thus remove this hack.

CPU0 CPU1 cpu_up cpu online hotplug_notifier(ONLINE) stopper(CPU1)->enabled = true; ... stop_machine() The conversion to smpboot threads moved the enablement to the wakeup path of the parked thread. The majority of users seem to have the following working order: CPU0 CPU1 cpu_up cpu online unpark_threads() wakeup(stopper[CPU1]) .... stopper thread runs stopper(CPU1)->enabled = true; stop_machine() But Konrad and Sander have observed: CPU0 CPU1 cpu_up cpu online unpark_threads() wakeup(stopper[CPU1]) .... stop_machine() stopper thread runs stopper(CPU1)->enabled = true; Now the stop machinery kicks CPU0 into the stop loop, where it gets stuck forever because the queue code saw stopper(CPU1)->enabled == false, so CPU0 waits for CPU1 to enter stomp_machine, but the CPU1 stopper work got discarded due to enabled == false. Add a pre_unpark function to the smpboot thread descriptor and call it before waking the thread. This fixes the problem at hand, but the stop_machine code should be more robust. The stopper->enabled flag smells fishy at best. Thanks to Konrad for going through a loop of debug patches and providing the information to decode this issue.

This patch adds support for platform specific data for SDIO fullmac devices. Currently OOB interrupts are configured by Kconfig BRCMFMAC_SDIO_OOB but that is now determined dynamically by checking availibility of platform data.

If 0 then a default value will be used. This is the target drive + * strength, the exact drive strength which will be used depends on the + * capabilities of the device. + * + * oob_irq_supported: does the board have support for OOB interrupts. SDIO + * in-band interrupts are relatively slow and for having less overhead on + * interrupt processing an out of band interrupt can be used. If the HW + * supports this then enable this by setting this field to true and configure + * the oob related fields. + * + * oob_irq_nr, oob_irq_flags: the OOB interrupt information. The values are + * used for registering the irq using request_irq function. + * + * power_on: This function is called by the brcmfmac when the module gets + * loaded. This can be particularly useful for low power devices. The platform + * spcific routine may for example decide to power up the complete device. + * If there is no use-case for this function then provide NULL. + * + * power_off: This function is called by the brcmfmac when the module gets + * unloaded.
