From cf417141cbb3a4ceb5cca15b2c1f099bd0a6603c Mon Sep 17 00:00:00 2001 From: Max Krasnyansky Date: Mon, 11 Aug 2008 14:33:53 -0700 Subject: [PATCH 001/269] sched, cpuset: rework sched domains and CPU hotplug handling (v4) This is an updated version of my previous cpuset patch on top of the latest mainline git. The patch fixes CPU hotplug handling issues in the current cpusets code. Namely circular locking in rebuild_sched_domains() and unsafe access to the cpu_online_map in the cpuset cpu hotplug handler. This version includes changes suggested by Paul Jackson (naming, comments, style, etc). I also got rid of the separate workqueue thread because it is now safe to call get_online_cpus() from workqueue callbacks. Here are some more details: rebuild_sched_domains() is the only way to rebuild sched domains correctly based on the current cpuset settings. What this means is that we need to be able to call it from different contexts, like cpu hotplug for example. Also latest scheduler code in -tip now calls rebuild_sched_domains() directly from functions like arch_reinit_sched_domains(). In order to support that properly we need to rework cpuset locking rules to avoid circular dependencies, which is what this patch does. New lock nesting rules are explained in the comments. We can now safely call rebuild_sched_domains() from virtually any context. The only requirement is that it needs to be called under get_online_cpus(). This allows cpu hotplug handlers and the scheduler to call rebuild_sched_domains() directly. The rest of the cpuset code now offloads sched domains rebuilds to a workqueue (async_rebuild_sched_domains()). This version of the patch addresses comments from the previous review. I fixed all miss-formated comments and trailing spaces. I also factored out the code that builds domain masks and split up CPU and memory hotplug handling. This was needed to simplify locking, to avoid unsafe access to the cpu_online_map from mem hotplug handler, and in general to make things cleaner. The patch passes moderate testing (building kernel with -j 16, creating & removing domains and bringing cpus off/online at the same time) on the quad-core2 based machine. It passes lockdep checks, even with preemptable RCU enabled. This time I also tested in with suspend/resume path and everything is working as expected.

This patch makes Linux PNPACPI ignore the bit. The ACPI spec contains examples of PCI Interrupt Link devices marked as ResourceProducers, but many BIOSes mark them as ResourceConsumers. I also checked with a Windows contact, who said: Windows uses only "resource consumer" when dealing with interrupts. There's no useful way of looking at a resource producer of interrupts. ... NT-based Windows largely infers the producer/consumer stuff from the device type and ignores the bits in the namespace. This was necessary because Windows 98 ignored them and early namespaces contained random junk. The reason I want to change this is because if PNPACPI devices exclude ResourceProducer IRQ resources, we can't write PNP drivers for those devices. For example, on machines such as the the HP rx7620, rx7640, rx8620, rx8640, and Superdome, HPET interrupts are ResourceProducers. The HPET driver currently has to use acpi_bus_register_driver() and do its own _CRS parsing, even though it requires absolutely no ACPI-specific functionality. It would be better if the HPET driver were a PNP driver and took advantage of the _CRS parsing built into PNPACPI. This producer/consumer check was originally added here: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=2b8de5f50e4a302b83ebcd5b0120621336d50bd6 to fix this bug: http://bugzilla.kernel.org/show_bug.cgi?id=6292 However, the bug was related only to memory and I/O port resources, where the distinction is sensible and important to Linux. Given that the distinction is muddled for IRQ resources, I think it was a mistake to add the check there.

Although there's no kernel support for the Java hardware yet, we need to be able to recover from this situation and keep the system running. This patch adds code to detect and fixup this situation in the critical exception handler and terminate the faulting process. We may have to rethink how to handle this more gracefully when the necessary kernel support for hardware-accelerated Java is added.

A side-effect of this is that the decision is now made once for each contiguous section in the LMB array rather than for each page individually. This can often mean that the whole of the linear mapping ends up being executable. This reverts to the previous behaviour, where individual pages are checked for being part of the kernel text or not, by moving the check back down into htab_bolt_mapping.

This ensures that CONFIG_FRAME_POINTER is only selected by ftrace. When CONFIG_FTRACE is enabled we also pass -mno-sched-epilog to work around the gcc codegen bug.

HW is not capable to sync TSF (it's constantly little behind). This creates constant IBSS merging upon reception of each beacon, adding and removing station which in turn creates above 50% packet loss and thus dramatically degrade the throughput. The W/A simply stops the driver from declaring it has a reliable TSF value and thus eliminates IBSS merging.

GFP_DMA allows allocation only for memory under 16M which causes allocation problems suspend/resume flows. Using kmalloc is temporal solution and some consistent/coherent allocation schema will be more correct. Since iwlwifi hardware supports 64bit address this solution should work on x86 (32 and 64bit) for now. This patch fixes memory freeing problem in the previous patch.

This patch adds a V4L2_CAP_SENSOR_UPSIDE_DOWN flag to the capabilities flags, and sets this flag for the Philips SPC200NC cam (which has its sensor installed upside down). The same flag is also needed and added for the Philips SPC300NC. Together with a patch to libv4l which adds flipping the image in software this fixes the upside down display with the SPC200NC cam.

The old Mediavision Pro Movie Studio legacy ISA V4L1 driver was found to hang the boot during Ingo Molnar's testing of randconfig kernels. Have it require a "pms.enable=1" kernel parameter to enable the driver when builtin which avoids such problems. This is a deprecated and, very likely, unused driver.

The proper behaviour is to keep all succeded devices registered; 4) both n_devs and minor were using 0 as permissions. Better to have them with 0444. With the current patch, if n_devs specify a very large value, it will register all possible devices. For example, on a machine without any other V4L drivers loaded, with this patch, we will have something like: vivi: V4L2 device registered as /dev/video0 vivi: V4L2 device registered as /dev/video1 vivi: V4L2 device registered as /dev/video2 ... vivi: V4L2 device registered as /dev/video31 video_register_device_index: get_index failed Video Technology Magazine Virtual Video Capture Board ver 0.5.0 successfully loaded. 5) The number of allocated devices on success is now kept at n_devs: $ cat /sys/module/vivi/parameters/n_devs 32 Thanks to Henne for pointing that there were some issues at vivi.

If accounting of a queue is in error, logic borrowed from ivtv will cause an oops when flushing the queues for a stream. This change greatly simplifies the queue flush logic, and sets the queue back to sane defaults on a flush.

Thus, instead of looking at the resource number to determine whether it was a bridge resource or a regular resource (they have different alignment rules), we should just ask the resource for its alignment directly. The reason this broke only cardbus resources was that for the other types of resources, the old way of deciding alignment actually still happened to work. But CardBus bridge resources had been changed by commit 934b7024f0ed29003c95cef447d92737ab86dc4f ("Fix cardbus resource allocation") to look more like regular resources than PCI bridge resources from an alignment handling standpoint.

This patch makes gspca claim the USB-ID for sn9c101/2 cams with a TAS5110C1B sensor even if both gspca and sn9c102 are enabled, as these cams are much better supported under gspca (and extensively tested with gspca). It also removes an usb-id from sn9c102 for one more unsupported bridge sensor combo.

When using the sonixb driver in a dark room and given that the autoexposure algorithm starts with a setting most suitable for daylight, the picture produced by the cam may actually be 100% black leading to a avg_lum value of 0, so an avg_lum value of 0 does not always signal an exposure settings change (which it normally does). This patch adds a check for the really black image case and stops dropping all frames as invalid in this case.

This results in less pointer hopping when many fingers are on the trackpad. In addition, a finger counting method based on pressure information from all fingers is introduced. Together with a pressure hysteresis window, this yields a more stable counting of the number of fingers on the trackpad.

This patch fixes a problem within the SH implementation of resume_kernel code, that implements in assembly the bulk of preempt_schedule_irq function without taking care of the extra code needed to handle the BKL preemptible. The patch basically consists of removing this asm code and calling the common C implementation (see kernel/sched.c) as other archs do. Another change is the missing 'cli' macro invocation at the beginning of the resume_kernel.

Use of wait irqs forces the hardware to pause and wait until the cpu is ready. Polling is also reworked in this patch to fix ms delay issues.

The new clockevent ends up with clockevents_handle_noop as event handler, resulting in no timer activity. The problematic path seems to be * old device already has hrtimer_interrupt as the event_handler * new clockevent device registers with a higher rating * tick_check_new_device() is called * clockevents_exchange_device() gets called * old->event_handler is set to clockevents_handle_noop * tick_setup_device() is called for the new device * which sets new->event_handler using the old->event_handler which is noop. Change the ordering so that new device inherits the proper handler. This does not have any issue in normal case as most likely all the clockevent devices are setup before the highres switch. But, can potentially be affecting some corner case where HPET force detect happens after the highres switch. This was a problem with HPET in MSI mode code that we have been experimenting with.

The suspected reason for the problem is that signal_struct maintains it's own utime and stime (of exited tasks), these are not updated using the new task_utime() routine, hence sig->utime can go backwards and cause the same problem to occur (sig->utime, adds tsk->utime and not task_utime()). This patch fixes the problem TODO: using max(task->prev_utime, derived utime) works for now, but a more generic solution is to implement cputime_max() and use the cputime_gt() function for comparison.

In particular, it doesn't contain the code for CPU feature words 2 (Transmeta), 3 (Linux-specific), 5 (VIA), or 7 (scattered). Zero them out, so we can still set those bits as known at compile time; in particular, this allows creating a Linux-specific NOPL flag and have it required (and therefore resolvable at compile time) in 64-bit mode.

Rozycki" Date: Fri, 5 Sep 2008 14:05:31 -0700 Subject: [PATCH 208/269] ntp: fix calculation of the next jiffie to trigger RTC sync We have a bug in the calculation of the next jiffie to trigger the RTC synchronisation. The aim here is to run sync_cmos_clock() as close as possible to the middle of a second. Which means we want this function to be called less than or equal to half a jiffie away from when now.tv_nsec equals 5e8 (500000000). If this is not the case for a given call to the function, for this purpose instead of updating the RTC we calculate the offset in nanoseconds to the next point in time where now.tv_nsec will be equal 5e8. The calculated offset is then converted to jiffies as these are the unit used by the timer. Hovewer timespec_to_jiffies() used here uses a ceil()-type rounding mode, where the resulting value is rounded up. As a result the range of now.tv_nsec when the timer will trigger is from 5e8 to 5e8 + TICK_NSEC rather than the desired 5e8 - TICK_NSEC / 2 to 5e8 + TICK_NSEC / 2. As a result if for example sync_cmos_clock() happens to be called at the time when now.tv_nsec is between 5e8 + TICK_NSEC / 2 and 5e8 to 5e8 + TICK_NSEC, it will simply be rescheduled HZ jiffies later, falling in the same range of now.tv_nsec again. Similarly for cases offsetted by an integer multiple of TICK_NSEC. This change addresses the problem by subtracting TICK_NSEC / 2 from the nanosecond offset to the next point in time where now.tv_nsec will be equal 5e8, effectively shifting the following rounding in timespec_to_jiffies() so that it produces a rounded-to-nearest result.

On those chipsets, we need to read out the timer value at least three times to get a correct result, for every once in a while (i.e. within a 3 ns window every 69.8 ns) the read returns a bogus result. During normal operation we work around this issue, but during initialization reading a bogus value may lead to -EINVAL even though the hardware is usable.

What this means is that doing echo 1 > /sys/devices/system/cpu/sched_mc_power_savings on a system with cpusets enabled will not take affect untill something changes in the cpuset setup (ie new sets created or deleted). This patch fixes restore correct behaviour where domains must be rebuilt in order to enable MC powersaving flags. Test on quad-core Core2 box with both CONFIG_CPUSETS and !CONFIG_CPUSETS. Also tested on dual-core Core2 laptop. Lockdep is happy and things are working as expected.

This is amazing stupidity in itself, but 2. nf_conntrack_irc helper use simple_strtoul() for DCC request parsing. Data first copied into 64KB buffer, so theoretically nothing prevents reading past the end of it, since data comes from network given 1). This is not actually a problem currently since we're guaranteed to have a 0 byte in skb_shared_info or in the buffer the data is copied to, but to make this more robust, make sure the string is actually terminated.

Jeff added the Marvell device identifiers to the ahci driver without making the AHCI driver handle the PATA port. This means a lot of users can't use current kernels and in most distro cases can't even install. This has been going on since March 2008 for the 6121 Marvell, and late 2007 for the 6145!!! This was all pointed out at the time and repeatedly ignored. Bugs assigned to Jeff about this are ignored also. To quote Jeff in email > "Just switch the order of 'ahci' and 'pata_marvell' in > /etc/modprobe.conf, then use Fedora's tools regenerate the initrd. > See? It's not rocket science, and the current configuration can be > easily made to work for Fedora users." (Which isn't trivial, isn't end user, shouldn't be needed, and as it usually breaks at install time is in fact impossible) To quote Jeff in August 2007 > " mv-ahci-pata > Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller > command' area before it is usable, and can go upstream." Only he add the ids anyway later and caused regressions, adding a further id in March causing more regresions. The actual fix for the moment is very simple. If the user has included the pata_marvell driver let it drive the ports. If they've only selected for SATA support give them the AHCI driver which will run the port a fraction faster. Allow the user to control this decision via ahci.marvell_enable as a module parameter so that distributions can ship 'it works' defaults and smarter users (or config tools) can then flip it over it desired.

The timewait sockets life cycle is not tied with the network namespace, that means the timewait sockets stay alive while the network namespace dies. The timewait sockets are for avoiding to receive a duplicate packet from the network, if the network namespace is freed, the network stack is removed, so no chance to receive any packets from the outside world. Furthermore, having a pending destruction timer on these sockets with a network namespace freed is not safe and will lead to an oops if the timer callback which try to access data belonging to the namespace like for example in: inet_twdr_do_twkill_work -> NET_INC_STATS_BH(twsk_net(tw), LINUX_MIB_TIMEWAITED); Purging the timewait sockets at the network namespace destruction will: 1) speed up memory freeing for the namespace 2) fix kernel panic on asynchronous timewait destruction Signed-off-by: Daniel Lezcano Acked-by: Denis V.

The Linux automounter uses the mount command's "-s" command line option ("s" for "sloppy") so that mount requests containing such options are not rejected. Commit f45663ce5fb30f76a3414ab3ac69f4dd320e760a attempted to address a known regression with text-based NFS mount option parsing. Unrecognized mount options would cause mount requests to fail, even if the "-s" option was used on the mount command line. Unfortunately, this commit was not complete as submitted. It adds a new mount option, "sloppy". But it is missing a hunk, so it now allows NFS mounts with unrecognized mount options, even if the "sloppy" option is not present. This could be a problem if a required critical mount option such as "sync" is misspelled, for example, and is considered a regression from 2.6.26. This patch restores the missing hunk. Now, the default behavior of text-based NFS mount options is as before: any unrecognized mount option will cause the mount to fail. Please include this in 2.6.27-rc.

The only exception here is PSM 1 for the service discovery protocol (SDP). It is meant to be used without any encryption since it contains only public information. This is how Bluetooth 2.0 and before handle connections on PSM 1. For Bluetooth 2.1 devices the pairing procedure differentiates between no bonding, general bonding and dedicated bonding. The L2CAP layer wrongly uses always general bonding when creating new connections, but it should not do this for SDP connections. In this case the authentication requirement should be no bonding and the just-works model should be used, but in case of non-SDP connection it is required to use general bonding. If the new connection requires man-in-the-middle (MITM) protection, it also first wrongly creates an unauthenticated link key and then later on requests an upgrade to an authenticated link key to provide full MITM protection. With Simple Pairing the link key generation is an expensive operation (compared to Bluetooth 2.0 and before) and doing this twice during a connection setup causes a noticeable delay when establishing a new connection. This should be avoided to not regress from the expected Bluetooth 2.0 connection times. The authentication requirements are known up-front and so enforce them. To fulfill these requirements the hci_connect() function has been extended with an authentication requirement parameter that will be stored inside the connection information and can be retrieved by userspace at any time. This allows the correct IO capabilities exchange and results in the expected behavior.

It is the initiators job to create a secure ACL link. However in case of malicious devices, the acceptor has to make sure that the ACL is encrypted before allowing any kind of L2CAP connection. The only exception here is the PSM 1 for the service discovery protocol, because that is allowed to run on an insecure ACL link. Previously it was enough to reject a L2CAP connection during the connection setup phase, but with Bluetooth 2.1 it is forbidden to do any L2CAP protocol exchange on an insecure link (except SDP). The new hci_conn_check_link_mode() function can be used to check the integrity of an ACL link. This functions also takes care of the cases where Security Mode 4 is disabled or one of the devices is based on an older specification.

This is also known as CVE-2008-1514. Test case available here: http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/tests/ptrace-tests/tests/user-area-padding.c?cvsroot=systemtap Steps to reproduce: 1) wget the above 2) gcc -o user-area-padding-31bit user-area-padding.c -Wall -ggdb2 -D_GNU_SOURCE -m31 3) ./user-area-padding-31bit Test status ----------- Without patch, both s390 and s390x kernels panic. With patch, the test case, as well as the gdb testsuite, pass without incident, padding area reads returning zero, writes ignored. Nb: original version returned -EINVAL on write attempts, which broke the gdb test and made the test case slightly unhappy, Jan Kratochvil suggested the change to return 0 on write attempts.

However, the current way its coded doesn't work on parisc64. For two reasons: 1) parisc isn't in the #ifdef and 2) parisc has a different format for function descriptors Make dereference_function_descriptor() more accommodating by allowing architecture overrides. I put the three overrides (for parisc64, ppc64 and ia64) in arch/kernel/module.c because that's where the kernel internal linker which knows how to deal with function descriptors sits.

This fixes kernel bugzilla 11469: "TUN with 1024 neighbours: ip6_dst_lookup_tail NULL crash" dst->neighbour is not necessarily hooked up at this point in the processing path, so blindly dereferencing it is the wrong thing to do. This NULL check exists in other similar paths and this case was just an oversight. Also fix the completely wrong and confusing indentation here while we're at it.
