* net: /proc/net/ip_mr_cache, display Iif as a signed shortBenjamin Thery2008-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | Today, iproute2 fails to show multicast forwarding unresolved cache entries while scanning /proc/net/ip_mr_cache. Indeed, it expects to see -1 in 'Iif' column to identify unresolved entries but the kernel outputs 65535. It's a signed/unsigned issue: 'Iif', the source interface, is retrieved from member mfc_parent in struct mfc_cache. mfc_parent is a vifi_t: unsigned short, but is displayed in ipmr_mfc_seq_show() as "%-3d", signed integer. In unresolevd entries, the 65535 value (0xFFFF) comes from this define: #define ALL_VIFS ((vifi_t)(-1)) That may explains why the guy who added support for this in iproute2 thought a -1 should be expected. I don't know if this must be fixed in kernel or in iproute2. Who is right? What is the correct API? How was it designed originally? I let you decide if it should goes in the kernel or be fixed in iproute2. Signed-off-by: Benjamin Thery <benjamin.thery@bull.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: fix /proc/net/ip_mr_cache display - V2Benjamin Thery2008-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | /proc/net/ip_mr_cache and /proc/net/ip6_mr_cache displays garbage when showing unresolved mfc_cache entries. [root@qemu tests]# cat /proc/net/ip_mr_cache Group Origin Iif Pkts Bytes Wrong Oifs 014C00EF 010014AC 1 10 10050 0 2:1 3:1 024C00EF 010014AC 65535 514 2 -559067475 The first line is correct. It is a resolved cache entry, 10 packets used it... The second line represents an unresolved entry, and the columns Pkts(4th), Bytes(5th) and Wrong(6th) just show garbage. In struct mfc_cache, there's an union to store data for resolved and unresolved cases. And what ipmr_mfc_seq_show() is printing in these columns for the unresolved entries is some bytes from mfc_cache.mfc_un.res. Bad. (eg. In our case -559067475 is in fact 0xdead4ead which is the spinlock magic from mfc_cache.mfc_un.unres.unresolved.lock.magic). This patch replaces the garbage data written in these columns for the unresolved entries by '0' (zeros) which is more correct. This change doesn't break the ABI. Also, mfc->mfc_un.res.pkt, mfc->mfc_un.res.bytes, mfc->mfc_un.res.wrong_if are unsigned long. It applies on top of net-next-2.6. The patch for net-2.6 is slightly different because of the NIP6_FMT to %pI6 conversion that was made in the seq_printf. Changelog: ========== V2: * Instead of breaking the ABI by suppressing the columns that have no meaning for unresolved entries, fill them with 0 values.

* atm: 32-bit ioctl compatibilityDavid Woodhouse2008-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We lack compat ioctl support through most of the ATM code. This patch deals with most of it, and I can now at least use BR2684 and PPPoATM with 32-bit userspace. I haven't added a .compat_ioctl method to struct atm_ioctl, because AFAICT none of the current users need any conversion -- so we can just call the ->ioctl() method in every case. I looked at br2684, clip, lec, mpc, pppoatm and atmtcp. In svc_compat_ioctl() the only mangling which is needed is to change COMPAT_ATM_ADDPARTY to ATM_ADDPARTY. Although it's defined as _IOW('a', ATMIOC_SPECIAL+4,struct atm_iobuf) it doesn't actually _take_ a struct atm_iobuf as an argument -- it takes a struct sockaddr_atmsvc, which _is_ the same between 32-bit and 64-bit code, so doesn't need conversion. Almost all of vcc_ioctl() would have been identical, so I converted that into a core do_vcc_ioctl() function with an 'int compat' argument. I've done the same with atm_dev_ioctl(), where there _are_ a few differences, but still it's relatively contained and there would otherwise have been a lot of duplication. I haven't done any of the actual device-specific ioctls, although I've added a compat_ioctl method to struct atmdev_ops.

* forcedeth: power down phy when interface is downEd Swierk2008-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bring the physical link down when the interface is down by placing the PHY in power-down state, unless WOL is enabled. This mirrors the behavior of other drivers including e1000 and tg3. Without the patch, ifconfig down leaves the physical link up, which confuses datacenter users who expect the link lights both on the NIC and the switch to go out when they bring an interface down. Furthermore, even though the phy is powered on, autonegotiation stops working, so a normally gigabit link might suddenly become 100 Mbit half-duplex when the interface goes down, and become gigabit when it comes up again. Ayaz said: I would not include this patch until further testing is performed. NVIDIA MCP chips use 3rd party PHY vendors. By powering down the phy, it could have adverse affects on certain phys. Arthur Jones said: I just ran across this patch. Tested on a Marvell 88E1121R (GigE PHY) and works great. This is a very important feature for me.

Create a new RFCOMM device (using RFCOMMCREATEDEV ioctl) 2. (Try to) open the device 3. Release the RFCOMM device (using RFCOMMRELEASEDEV ioctl) At this point, the "/dev/rfcomm*" device is still in use, but it is gone from the internal list, so the device id can be reused. 4. Create a new RFCOMM device with the same device id as before And now kobject will complain that the TTY already exists. (See http://lkml.org/lkml/2008/7/13/89 for a reproducible test-case.) This patch attempts to correct this by only removing the device from the internal list of devices at the final unregister stage, so that the id won't get reused until the device has been completely destructed. This should be safe as the RFCOMM_TTY_RELEASED bit will be set for the device and prevent the device from being reopened after it has been released.

The Bluetooth 1.0b specification was ambiguous on how the device firmware was suppose to handle it. Almost every device was triggering a transport reset at the same time. In case of USB this ended up in disconnects from the bus. All modern Bluetooth dongles handle this perfectly fine and a lot of them actually require that HCI Reset is sent. If not then they are either stuck in their HID Proxy mode or their internal structures for inquiry and paging are not correctly setup. To handle old and new devices smoothly the Bluetooth subsystem contains a quirk to force the HCI Reset on initialization. However maintaining such a quirk becomes more and more complicated. This patch turns the logic around and lets the old devices disable the HCI Reset command. The only device where the HCI_QUIRK_NO_RESET is still needed are the original Digianswer devices and dongles with an early CSR firmware. CSR reported that they fixed this for version 12 firmware. The last official release of version 11 firmware is build ID 115. The first version 12 candidate was build ID 117. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The iTCO_wdt code was not clearing the correct bits. It now clears the timeout status bit and then the SECOND_TO_STS bit and then the BOOT_STS bit. Note: we should first clear the SECOND_TO_STS bit before clearing the BOOT_STS bit.
