7731ce6 Rafael J. Wysocki 30 March 2008, 01:19:07 UTC ACPI PM: Restore the 2.6.24 suspend ordering Some time ago it turned out that our suspend code ordering broke some NVidia-based systems that hung if _PTS was executed with one of the PCI devices, specifically a USB controller, in a low power state. Then, it was noticed that the suspend code ordering was not compliant with ACPI 1.0, although it was compliant with ACPI 2.0 (and later), and it was argued that the code had to be changed for that reason (ref. http://bugzilla.kernel.org/show_bug.cgi?id=9528). So we did, but evidently we did wrong, because it's now turning out that some systems have been broken by this change. Refs: http://bugzilla.kernel.org/show_bug.cgi?id=10340 https://bugzilla.novell.com/show_bug.cgi?id=374217#c16 [ I said at that time that something like this might happend, but the majority of people involved thought that it was improbable due to the necessity to preserve the compliance of hardware with ACPI 1.0. ] This actually is a quite serious regression from 2.6.24. Moreover, the ACPI 1.0 ordering of suspend code introduced another issue that I have only noticed recently. Namely, if the suspend of one of devices fails, the already suspended devices will be resumed without executing _WAK before, which leads to problems on some systems (for example, in such situations thermal management is broken on my HP nx6325). Consequently, it also breaks suspend debugging on the affected systems. Note also, that the requirement to execute _PTS before suspending devices does not really make sense, because the device in question may be put into a low power state at run time for a reason unrelated to a system-wide suspend. For the reasons outlined above, the change of the suspend ordering should be reverted, which is done by the patch below. [ Felix Möller: "I am the reporter from the original Novell Bug: https://bugzilla.novell.com/show_bug.cgi?id=374217 I just tried current git head (two hours ago) with the patch (the one from the beginning of this thread) from Rafael and without it.

cabce28 Mikulas Patocka 31 March 2008, 23:22:45 UTC plip: replace spin_lock_irq with spin_lock_irqsave in irq context Plip uses spin_lock_irq/spin_unlock_irq in its IRQ handler (called from parport IRQ handler), the latter enables interrupts without parport subsystem IRQ handler expecting it. The bug can be seen if you compile kernel with lock dependency checking and use plip --- it produces a warning. This patch changes it to spin_lock_irqsave/spin_lock_irqrestore, so that it doesn't enable interrupts when already disabled.

This is achieved by just giving user a chance to define the clock explicitly in the board config. via CONFIG_SOC_AU1000_FREQUENCY option, defaulting to 396 MHz if the option is not given...

These messages are a regression compared with 2.6.24, which did not flood the syslog with them. The actual underlying problem was introduced in 2.6.23, when somebody made the string parsing no longer accept nul-terminated strings as a valid input to store_uevent(). Eg. "add\0" was valid prior to 2.6.23, where the code regressed to require "add" without the '\0'. This patch fixes the 2.6.23 / 2.6.24 regressions, by having the code once again tolerate the trailing '\0', if present. According to GregKH, this mainly affects older Ubuntu systems, such as the one I have here that requires this fix.

It moves the few places that needs change to wrappers to that other architectures with similar issues can easily add their own changes to those wrappers, at least until we have more useful generic kernel API.

[ conflict in drivers/ide/ide-probe.c fixed manually ] It turned out that probing order change causes problems for some drives: http://bugzilla.kernel.org/show_bug.cgi?id=10239 Since root causes are still being investigated and are unlikely to be fixed before 2.6.25 lets revert this change for now. As a result cable detection becomes less reliable when compared with 2.6.24 but the affected drives are useable again.

d478376 Jesper Juhl 28 March 2008, 21:16:12 UTC driver core: fix small mem leak in driver_add_kobj() The Coverity checker spotted that we leak the storage allocated to 'name' in int driver_add_kobj(). The leak looks legit to me - this is the code : int driver_add_kobj(struct device_driver *drv, struct kobject *kobj, const char *fmt, ...) { va_list args; char *name; int ret; va_start(args, fmt); name = kvasprintf(GFP_KERNEL, fmt, args); ^^^^^^^^ This dynamically allocates space... va_end(args); if (!name) return -ENOMEM; return kobject_add(kobj, &drv->p->kobj, "%s", name); ^^^^^^^^ This neglects to free the space allocated } Inside kobject_add() a copy of 'name' will be made and used. As far as I can see, Coverity is correct in flagging this as a leak, but I'd like some configmation before the patch is applied. This should fix it.

If write requests need to be split into pieces, the code must not process them in parallel because the crypto context cannot be shared. So there can be parallel crypto operations on one part of the write, but only one write bio can be processed at a time. This is not optimal and the workqueue code needs to be optimized for parallel processing, but for now it solves the problem without affecting the performance of synchronous crypto operation (most of current dm-crypt users). http://bugzilla.kernel.org/show_bug.cgi?id=10242 http://bugzilla.kernel.org/show_bug.cgi?id=10207 Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com> Cc: "Rafael J.

This means that this quirk is unsafe and has to be removed. I also added a comment to help developers realize that adding new IDs to this SMBus unhiding quirk table should be done only with great care, and in particular only after checking that ACPI is not making use of the SMBus.

This is reasonable because if page already has buffer then generic_write_begin was called previously.

1f71f50 Roland Dreier 28 March 2008, 17:28:17 UTC RDMA/cxgb3: Program hardware IRD with correct value Because of a typo in iwch_accept_cr(), the cxgb3 connection handling code programs the hardware IRD (incoming RDMA read queue depth) with the value that is passed in for the ORD (outgoing RDMA read queue depth). In particular this means that if an application passes in IRD > 0 and ORD = 0 (which is a completely sane and valid thing to do for an app that expects only incoming RDMA read requests), then the hardware will end up programmed with IRD = 0 and the app will fail in a mysterious way. Fix this by using "ep->ird" instead of "ep->ord" in the intended place.

a2ceff5 Michael Ellerman 28 March 2008, 08:11:48 UTC [POWERPC] Fix missed hardware breakpoints across multiple threads There is a bug in the powerpc DABR (data access breakpoint) handling, which can result in us missing breakpoints if several threads are trying to break on the same address. The circumstances are that do_page_fault() calls do_dabr(), this clears the DABR (sets it to 0) and sets up the signal which will report to userspace that the DABR was hit. The do_signal() code will restore the DABR value on the way out to userspace. If we reschedule before calling do_signal(), __switch_to() will check the cached DABR value and compare it to the new thread's value, if they match we don't set the DABR in hardware. So if two threads have the same DABR value, and we schedule from one to the other after taking the interrupt for the first thread hitting the DABR, the second thread will run without the DABR set in hardware. The cleanest fix is to move the cache update into set_dabr(), that way we can't forget to do it.
