| 25fb6ca | Balakumaran Kannan | 02 April 2013, 10:45:05 UTC | net IPv6 : Fix broken IPv6 routing table after loopback down-up IPv6 Routing table becomes broken once we do ifdown, ifup of the loopback(lo) interface. After down-up, routes of other interface's IPv6 addresses through 'lo' are lost. IPv6 addresses assigned to all interfaces are routed through 'lo' for internal communication. Once 'lo' is down, those routing entries are removed from routing table. But those removed entries are not being re-created properly when 'lo' is brought up. So IPv6 addresses of other interfaces becomes unreachable from the same machine. Also this breaks communication with other machines because of NDISC packet processing failure. This patch fixes this issue by reading all interface's IPv6 addresses and adding them to IPv6 routing table while bringing up 'lo'. ==Testing== Before applying the patch: $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ sudo ifdown lo $ sudo ifup lo $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ After applying the patch: $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ sudo ifdown lo $ sudo ifup lo $ route -A inet6 Kernel IPv6 routing table Destination Next Hop Flag Met Ref Use If 2000::20/128 :: U 256 0 0 eth0 fe80::/64 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo ::1/128 :: Un 0 1 0 lo 2000::20/128 :: Un 0 1 0 lo fe80::xxxx:xxxx:xxxx:xxxx/128 :: Un 0 1 0 lo ff00::/8 :: U 256 0 0 eth0 ::/0 :: !n -1 1 1 lo $ Signed-off-by: Balakumaran Kannan <Balakumaran.Kannan@ap.sony.com> Signed-off-by: Maruthi Thotad <Maruthi.Thotad@ap.sony.com> Signed-off-by: David S.

| c1681bf | Anatol Pomozov | 01 April 2013, 16:47:56 UTC | loop: prevent bdev freeing while device in use struct block_device lifecycle is defined by its inode (see fs/block_dev.c) - block_device allocated first time we access /dev/loopXX and deallocated on bdev_destroy_inode. When we create the device "losetup /dev/loopXX afile" we want that block_device stay alive until we destroy the loop device with "losetup -d". But because we do not hold /dev/loopXX inode its counter goes 0, and inode/bdev can be destroyed at any moment. Usually it happens at memory pressure or when user drops inode cache (like in the test below). When later in loop_clr_fd() we want to use bdev we have use-after-free error with following stack: BUG: unable to handle kernel NULL pointer dereference at 0000000000000280 bd_set_size+0x10/0xa0 loop_clr_fd+0x1f8/0x420 [loop] lo_ioctl+0x200/0x7e0 [loop] lo_compat_ioctl+0x47/0xe0 [loop] compat_blkdev_ioctl+0x341/0x1290 do_filp_open+0x42/0xa0 compat_sys_ioctl+0xc1/0xf20 do_sys_open+0x16e/0x1d0 sysenter_dispatch+0x7/0x1a To prevent use-after-free we need to grab the device in loop_set_fd() and put it later in loop_clr_fd(). The issue is reprodusible on current Linus head and v3.3. Here is the test: dd if=/dev/zero of=loop.file bs=1M count=1 while [ true ]; do losetup /dev/loop0 loop.file echo 2 > /proc/sys/vm/drop_caches losetup -d /dev/loop0 done [ Doing bdgrab/bput in loop_set_fd/loop_clr_fd is safe, because every time we call loop_set_fd() we check that loop_device->lo_state is Lo_unbound and set it to Lo_bound If somebody will try to set_fd again it will get EBUSY. And if we try to loop_clr_fd() on unbound loop device we'll get ENXIO. loop_set_fd/loop_clr_fd (and any other loop ioctl) is called under loop_device->lo_ctl_mutex. ] Signed-off-by: Anatol Pomozov <anatol.pomozov@gmail.com> Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> | 01 April 2013, 22:48:47 UTC |

| 3893b27 | Sergei Shtylyov | 31 March 2013, 09:54:20 UTC | sh_eth: workaround for spurious ECI interrupt At least on Renesas R8A7778, EESR.ECI interrupt seems to fire regardless of its mask in EESIPR register. I can 100% reproduce it with the following scenario: target is booted with 'ip=on' option, and so IP-Config opens SoC Ether device but doesn't get a proper reply and then succeeds with on-board SMC chip; then I login and try to bring up the SoC Ether device with 'ifconfig', and I get an ECI interrupt once request_irq() is called by sh_eth_open() (while interrupt mask in EESIPR register is all 0), if that interrupt is accompanied by a pending EESR.FRC (frame receive completion) interrupt, I get kernel oops in sh_eth_rx() because sh_eth_ring_init() hasn't been called yet! The solution I worked out is the following: in sh_eth_interrupt(), mask the interrupt status from EESR register with the interrupt mask from EESIPR register in order not to handle the disabled interrupts -- but forcing EESIPR.M_ECI bit in this mask set because we always need to fully handle EESR.ECI interrupt in sh_eth_error() in order to quench it (as it doesn't get cleared by just writing 1 to the this bit as all the other interrupts). While at it, remove unneeded initializer for 'intr_status' variable and give it *unsigned long* type, matching the type of sh_eth_read()'s result; fix comment.

It's probably enough to say that this code is executed only on the LINK change interrupt (sic!) but even if we actually have the signal and choose to ignore it (it might be connected to PHY's link/activity LED output as on the Renesas BOCK-W board), sh_eth_adjust_link() on which this code relies to update 'mdp->link' gets executed later than the LINK change interrupt where it is checked, and so RX/TX never get enabled via ECMR register. So, ignore the LINK changed interrupt iff LINK signal is absent (or just chosen not to be used) or PSR register is absent, and enable/disable RX/TX directly in sh_eth_adjust_link() in this case.

| 00cfec3 | Eric Dumazet | 29 March 2013, 03:01:22 UTC | net: add a synchronize_net() in netdev_rx_handler_unregister() commit 35d48903e97819 (bonding: fix rx_handler locking) added a race in bonding driver, reported by Steven Rostedt who did a very good diagnosis : <quoting Steven> I'm currently debugging a crash in an old 3.0-rt kernel that one of our customers is seeing. The bug happens with a stress test that loads and unloads the bonding module in a loop (I don't know all the details as I'm not the one that is directly interacting with the customer). But the bug looks to be something that may still be present and possibly present in mainline too. It will just be much harder to trigger it in mainline. In -rt, interrupts are threads, and can schedule in and out just like any other thread. Note, mainline now supports interrupt threads so this may be easily reproducible in mainline as well. I don't have the ability to tell the customer to try mainline or other kernels, so my hands are somewhat tied to what I can do. But according to a core dump, I tracked down that the eth irq thread crashed in bond_handle_frame() here: slave = bond_slave_get_rcu(skb->dev); bond = slave->bond; <--- BUG the slave returned was NULL and accessing slave->bond caused a NULL pointer dereference. Looking at the code that unregisters the handler: void netdev_rx_handler_unregister(struct net_device *dev) { ASSERT_RTNL(); RCU_INIT_POINTER(dev->rx_handler, NULL); RCU_INIT_POINTER(dev->rx_handler_data, NULL); } Which is basically: dev->rx_handler = NULL; dev->rx_handler_data = NULL; And looking at __netif_receive_skb() we have: rx_handler = rcu_dereference(skb->dev->rx_handler); if (rx_handler) { if (pt_prev) { ret = deliver_skb(skb, pt_prev, orig_dev); pt_prev = NULL; } switch (rx_handler(&skb)) { My question to all of you is, what stops this interrupt from happening while the bonding module is unloading? What happens if the interrupt triggers and we have this: CPU0 CPU1 ---- ---- rx_handler = skb->dev->rx_handler netdev_rx_handler_unregister() { dev->rx_handler = NULL; dev->rx_handler_data = NULL; rx_handler() bond_handle_frame() { slave = skb->dev->rx_handler; bond = slave->bond; <-- NULL pointer dereference!!! What protection am I missing in the bond release handler that would prevent the above from happening? </quoting Steven> We can fix bug this in two ways. First is adding a test in bond_handle_frame() and others to check if rx_handler_data is NULL. A second way is adding a synchronize_net() in netdev_rx_handler_unregister() to make sure that a rcu protected reader has the guarantee to see a non NULL rx_handler_data. The second way is better as it avoids an extra test in fast path.

Similarly, a short read for such an object indicates that the remainder of the read should be interpreted a full read with zeros filling out the end of the request. This behavior is not correct for objects that are not backing rbd image data. Currently rbd_img_obj_request_callback() assumes it should be done for all objects. Change rbd_img_obj_request_callback() so it only does this zeroing for image objects. Encapsulate that special handling in its own function. Add an assertion that the image object request is a bio request, since we assume that (and we currently don't support any other types). This resolves a problem identified here: http://tracker.ceph.com/issues/4559 The regression was introduced by bf0d5f503dc11d6314c0503591d258d60ee9c944.

| f85eda8 | Nicholas Bellinger | 29 March 2013, 06:06:00 UTC | target: Fix RESERVATION_CONFLICT status regression for iscsi-target special case This patch fixes a regression introduced in v3.8-rc1 code where a failed target_check_reservation() check in target_setup_cmd_from_cdb() was causing an incorrect SAM_STAT_GOOD status to be returned during a WRITE operation performed by an unregistered / unreserved iscsi initiator port. This regression is only effecting iscsi-target due to a special case check for TCM_RESERVATION_CONFLICT within iscsi_target_erl1.c:iscsit_execute_cmd(), and was still correctly disallowing WRITE commands from backend submission for unregistered / unreserved initiator ports, while returning the incorrect SAM_STAT_GOOD status due to the missing SAM_STAT_RESERVATION_CONFLICT assignment. This regression was first introduced with: commit de103c93aff0bed0ae984274e5dc8b95899badab Author: Christoph Hellwig <hch@lst.de> Date: Tue Nov 6 12:24:09 2012 -0800 target: pass sense_reason as a return value Go ahead and re-add the missing SAM_STAT_RESERVATION_CONFLICT assignment during a target_check_reservation() failure, so that iscsi-target code sends the correct SCSI status.

VM_POPULATE only has any effect when userspace plays racy games with vmas by trying to unmap and remap memory regions that mmap or mlock are operating on. Also, the only effect of VM_POPULATE when userspace plays such games is that it avoids populating new memory regions that get remapped into the address range that was being operated on by the original mmap or mlock calls. Let's remove VM_POPULATE as there isn't any strong argument to mandate a new vm_flag.

As for the iwlwifi bits, Johannes says: "I have three little fixes to the driver from Emmanuel. One addresses a small bug Ben Hutchings found during the stable review process and two address some warnings in the driver when RF-Kill is asserted." Along with those...

Among these interrupts there are the Gigabits Ethernet ones used by the mvneta driver. Unfortunately the state of the percpu_irq API prevents the driver to use it. Indeed the interrupts have to be freed when the .stop() function is called. As the free_percpu_irq() function don't disable the interrupt line, we have to do it on each CPU before calling this. The function disable_percpu_irq() only disable the percpu on the current CPU and there is no function which allows to disable a percpu irq on a given CPU. Waiting for the extension of the percpu_irq API, this fix allows to use again the mvneta driver.

| db1d607 | Josef Bacik | 26 March 2013, 19:29:11 UTC | Btrfs: hold the ordered operations mutex when waiting on ordered extents We need to hold the ordered_operations mutex while waiting on ordered extents since we splice and run the ordered extents list. We need to make sure anybody else who wants to wait on ordered extents does actually wait for them to be completed. This will keep us from bailing out of flushing in case somebody is already waiting on ordered extents to complete.

Rename is just some random huge number and unlink accounts for tree log operations that don't actually happen during unlink, not to mention the tree log doesn't take from the trans block rsv anyway so it's completely useless.

| f4881bc | Josef Bacik | 25 March 2013, 20:03:35 UTC | Btrfs: fix space leak when we fail to reserve metadata space Dave reported a warning when running xfstest 275. We have been leaking delalloc metadata space when our reservations fail. This is because we were improperly calculating how much space to free for our checksum reservations. The problem is we would sometimes free up space that had already been freed in another thread and we would end up with negative usage for the delalloc space. This patch fixes the problem by calculating how much space the other threads would have already freed, and then calculate how much space we need to free had we not done the reservation at all, and then freeing any excess space. This makes xfstests 275 no longer have leaked space.

That is because is_extent_unchanged had no support for holes being punched. With this patch, instead of returning EIO we just return 0 (== the extent is not unchanged) and we're good.

| 265c3c0 | Lee Jones | 27 March 2013, 14:13:53 UTC | ARM: ux500: Enable the clock controlling Ethernet on Snowball This fixes a regression introduced by common clk enablement. On some u8500 based boards, the FMSC clock which is usually used for flash, is wired up to the SMSC911x Ethernet driver. However, the SMSC911x doesn't have common clk support yet, rendering it unusable. Prior to the introduction of common clk the FMSC clock was default on; however, common clk disables all clocks by default and insists drivers take responsibility to enable theirs. This fix enables the FMSC clock on Snowball, subsequently turning on the SMSC911x Ethernet chip. It will be removed when the driver is compatible with common clk.

One area from program memory (TCPM) and one for data memory (TCDM). The PRCMU needs to know where these are in order to function correctly. However, these are currently passed though platform device resources, which can only be obtained if Device Tree booting isn't in use. Thus we must also support them in DT by supplying them through the PRCMU node.

I created a minimal patch suited for stable, only changing this particular define. (Once net is merged back to net-next, I'll post a patch to uniformly use a SJA1000_ prefix for the sja100 private defines.) If you prefer, I can squash both patches together.
