2008-12-01[WATCHDOG] hpwdt: Fix kdump when using hpwdtBernhard Walle
When the "hpwdt" module is loaded (even if the /dev/watchdog device is not opened), then kdump does not work. The panic kernel either does not start at all or crash in various places. The problem is that hpwdt_pretimeout is registered with register_die_notifier() with the highest possible priority. Because it returns NOTIFY_STOP, the crash_nmi_callback which is also registered with register_die_notifier() is never executed. This causes the shutdown of other CPUs to fail. Reverting the order is no option: The crash_nmi_callback executes HLT and so never returns normally. Because of that, it must be executed as last notifier, which currently is done. So, that patch returns NOTIFY_OK to keep the crash_nmi_callback executed.

2008-11-21[WATCHDOG] hpwdt: set the mapped BIOS address space as executableBernhard Walle
The address provided by the SMBIOS/DMI CRU information is mapped via ioremap() in the virtual address space. However, since the address is executed (i.e. call'd), we need to set that pages as executable. Without that, I get following oops on a HP ProLiant DL385 G2 machine with BIOS from 05/29/2008 when I trigger crashdump: BUG: unable to handle kernel paging request at ffffc20011090c00 IP: [<ffffc20011090c00>] 0xffffc20011090c00 PGD 12f813067 PUD 7fe6a067 PMD 7effe067 PTE 80000000fffd3173 Oops: 0011 [1] SMP last sysfs file: /sys/devices/system/cpu/cpu3/cache/index2/shared_cpu_map CPU 1 Modules linked in: autofs4 ipv6 af_packet cpufreq_conservative cpufreq_userspace cpufreq_powersave powernow_k8 fuse loop dm_mod rtc_cmos ipmi_si sg rtc_core i2c _piix4 ipmi_msghandler bnx2 sr_mod container button i2c_core hpilo joydev pcspkr rtc_lib shpchp hpwdt cdrom pci_hotplug usbhid hid ff_memless ohci_hcd ehci_hcd uhci_hcd usbcore edd ext3 mbcache jbd fan ide_pci_generic serverworks ide_core p ata_serverworks pata_acpi cciss ata_generic libata scsi_mod dock thermal process or thermal_sys hwmon Supported: Yes Pid: 0, comm: swapper Not tainted 2.6.27.5-HEAD_20081111100657-default #1 RIP: 0010:[<ffffc20011090c00>] [<ffffc20011090c00>] 0xffffc20011090c00 RSP: 0018:ffff88012f6f9e68 EFLAGS: 00010046 RAX: 0000000000000d02 RBX: 0000000000000000 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000000 RBP: ffff88012f6f9e98 R08: 666666666666660a R09: ffffffffa1006fc0 R10: 0000000000000000 R11: ffff88012f6f3ea8 R12: ffffc20011090c00 R13: ffff88012f6f9ee8 R14: 000000000000000e R15: 0000000000000000 FS: 00007ff70b29a6f0(0000) GS:ffff88012f6512c0(0000) knlGS:0000000000000000 CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b CR2: ffffc20011090c00 CR3: 0000000000201000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process swapper (pid: 0, threadinfo ffff88012f6f2000, task ffff88007fa8a1c0) Stack: ffffffffa0f8502b 0000000000000002 ffffffff80738d50 0000000000000000 0000000000000046 0000000000000046 00000000fffffffe ffffffffa0f852ec 0000000000000000 ffffffff804ad9a6 0000000000000000 0000000000000000 Call Trace: Inexact backtrace: <NMI> [<ffffffffa0f8502b>] ? asminline_call+0x2b/0x55 [hpwdt] [<ffffffffa0f852ec>] hpwdt_pretimeout+0x3c/0xa0 [hpwdt] [<ffffffff804ad9a6>] ? notifier_call_chain+0x29/0x4c [<ffffffff802587e4>] ? notify_die+0x2d/0x32 [<ffffffff804abbdc>] ? default_do_nmi+0x53/0x1d9 [<ffffffff804abd90>] ? do_nmi+0x2e/0x43 [<ffffffff804ab552>] ? nmi+0xa2/0xd0 [<ffffffff80221ef9>] ? native_safe_halt+0x2/0x3 <<EOE>> [<ffffffff8021345d>] ? default_idle+0x38/0x54 [<ffffffff8021359a>] ? c1e_idle+0x118/0x11c [<ffffffff8020b3b5>] ? cpu_idle+0xa9/0xf1 Code: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff <55> 50 e8 00 00 00 00 58 48 2d 07 10 40 00 48 8b e8 58 e9 68 02 RIP [<ffffc20011090c00>] 0xffffc20011090c00 RSP <ffff88012f6f9e68> CR2: ffffc20011090c00 Kernel panic - not syncing: Fatal exception Signed-off-by: Bernhard Walle <bwalle@suse.de> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> Cc: Ingo Molnar <mingo@elte.hu> Acked-by: "H.

If the device is suspended with the cable disconnected, then resumed with the cable connected, dev->open is called before resume. During resume, we request an IRQ, but the IRQ was already assigned during dev->open, resulting in the warning shown below. Don't request an IRQ if the device is running.

There's a bug in the usbmon binary reader: When using read() to fetch the packets and a packet's data is partially read, the next read call will once again return up to len_cap bytes of data. The b_read counter is not regarded when determining the remaining chunk size. So, when dumping USB data with "cat /dev/usbmon0 > usbmon.trace" while reading from a USB storage device and analyzing the dump file afterwards it will get out of sync after a couple of packets.

2008-11-19USB: fix SB700 usb subsystem hang bugAndiry Xu
This patch is required for AMD SB700 south bridge revision A12 and A13 to avoid USB subsystem hang symptom. The USB subsystem hang symptom is observed when the system has multiple USB devices connected to it. In some cases a USB hub may be required to observe this symptom. This patch works around the problem by correcting the internal register setting that will help by changing the behavior of the internal logic to avoid the USB subsystem hang issue. The change in the behavior of the logic does not impact the normal operation of the USB subsystem.

2008-11-19lcd: fix oops if driver only interested in .set_powerBen Dooks
The LCD driver core calls LCD drivers when either the blanking state or the display mode has changed, but does not make any check to see if the called driver has a .set_mode method. This means if a driver only has a .set_power method then the system will OOPS on changing mode (and with the console semaphore held so you cannot easily see the problem). Fix the problem by ensuring that either callback is valid before use.

2008-11-19pxa2xx_spi: bugfix full duplex dma data corruptionNed Forrester
Fixes a data corruption bug in pxa2xx_spi.c when operating in full duplex mode with DMA and using buffers that overlap. SPI transmit and receive buffers are allowed to be the same or to overlap. However, this driver fails if such overlap is attempted in DMA mode because it maps the rx and tx buffers in the wrong order. By mapping DMA_FROM_DEVICE (read) before DMA_TO_DEVICE (write), it invalidates the cache before flushing it, thus discarding data which should have been transmitted. The patch corrects the order of mapping. This bug exists in all versions of pxa2xx_spi.c; similar bugs are in the drivers for two other SPI controllers (au1500, imx). A version of this patch has been tested on kernel 2.6.20 using verification of loopback data with: random transfer length, random bits-per-word, random positive offsets (both larger and smaller than transfer length) between the start of the rx and tx buffers, and varying clock rates.

2008-11-19phylib: Fix auto-negotiation restart avoidanceTrent Piepho
A previous patch, 51e2a3846eab18711f4eb59cd0a4c33054e2980a, made genphy_config_aneg() not restart aneg by calling genphy_restart_aneg() if the advertisement hadn't changed. But, genphy_restart_aneg() doesn't just restart aneg, it may also *enable* aneg or un-isolate the PHY from the MII (those functions are controlled by the same register). The code to avoid calling genphy_restart_aneg() didn't consider this. So, modify genphy_config_aneg() to also check if the PHY needs to have aneg enabled or be un-isolated before deciding not to restart aneg. This caused a problem with certain Davicom PHYs, as that driver isolates the PHY (why?) before calling genphy_config_aneg() and expects the PHY to be un-isolated by that function.

2008-11-18iwlagn: fix RX skb alignmentJohannes Berg
So I dug deeper into the DMA problems I had with iwlagn and a kind soul helped me in that he said something about pci-e alignment and mentioned the iwl_rx_allocate function to check for crossing 4KB boundaries. Since there's 8KB A-MPDU support, crossing 4k boundaries didn't seem like something the device would fail with, but when I looked into the function for a minute anyway I stumbled over this little gem: BUG_ON(rxb->dma_addr & (~DMA_BIT_MASK(36) & 0xff)); Clearly, that is a totally bogus check, one would hope the compiler removes it entirely. (Think about it) After fixing it, I obviously ran into it, nothing guarantees the alignment the way you want it, because of the way skbs and their headroom are allocated. I won't explain that here nor double-check that I'm right, that goes beyond what most of the CC'ed people care about. So then I came up with the patch below, and so far my system has survived minutes with 64K pages, when it would previously fail in seconds. And I haven't seen a single instance of the TX bug either. But when you see the patch it'll be pretty obvious to you why. This should fix the following reported kernel bugs: http://bugzilla.kernel.org/show_bug.cgi?id=11596 http://bugzilla.kernel.org/show_bug.cgi?id=11393 http://bugzilla.kernel.org/show_bug.cgi?id=11983 I haven't checked if there are any elsewhere, but I suppose RHBZ will have a few instances too... I'd like to ask anyone who is CC'ed (those are people I know ran into the bug) to try this patch. I am convinced that this patch is correct in spirit, but I haven't understood why, for example, there are so many unmap calls. I'm not entirely convinced that this is the only bug leading to the TX reply errors. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
