Here's a quote of the comment about the BUG macro from asm-generic/bug.h: Don't use BUG() or BUG_ON() unless there's really no way out; one example might be detecting data structure corruption in the middle of an operation that can't be backed out of. If the (sub)system can somehow continue operating, perhaps with reduced functionality, it's probably not BUG-worthy. If you're tempted to BUG(), think again: is completely giving up really the *only* solution? There are usually better options, where users don't need to reboot ASAP and can mostly shut down cleanly. In our case, the status flag of a ring buffer slot is managed from both sides, the kernel space and the user space. This means that even though the kernel side might work as expected, the user space screws up and changes this flag right between the send(2) is triggered when the flag is changed to TP_STATUS_SENDING and a given skb is destructed after some time. Then, this will hit the BUG macro. As David suggested, the best solution is to simply remove this statement since it cannot be used for kernel side internal consistency checks. I've tested it and the system still behaves /stable/ in this case, so in accordance with the above comment, we should rather remove it.

One condition before codel_Newton_step() was not good if we never left the dropping state for a flow. As a result rec_inv_sqrt was 0, instead of the ~0 initial value. codel control law was then set to a very aggressive mode, dropping many packets before reaching 'target' and recovering from this problem. To keep codel_vars_init() as efficient as possible, refine the condition to make sure rec_inv_sqrt initial value is correct Many thanks to Anton Mich for discovering the issue and suggesting a fix.

John W. Linville says: ==================== Here is a handful of fixes intended for 3.6. Daniel Drake offers a cfg80211 fix to consume pending events before taking a wireless device down. This prevents a resource leak. Stanislaw Gruszka gives us a fix for a NULL pointer dereference in rt61pci. Johannes Berg provides an iwlwifi patch to disable "greenfield" mode. Use of that mode was causing a rate scaling problem in for iwlwifi. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

commit be9f4a44 (ipv4: tcp: remove per net tcp_sock) added a selinux regression, reported and bisected by John Stultz selinux_ip_postroute_compat() expect to find a valid sk->sk_security pointer, but this field is NULL for unicast_sock It turns out that unicast_sock are really temporary stuff to be able to reuse part of IP stack (ip_append_data()/ip_push_pending_frames()) Fact is that frames sent by ip_send_unicast_reply() should be orphaned to not fool LSM. Note IPv6 never had this problem, as tcp_v6_send_response() doesnt use a fake socket at all.

During probe, every function probed clears the recovery registers from all functions on its path - thus signaling that given a future recovery event, there will be no need to wait for those functions. This is a flawed behaviour - each function should only be responsible for its own bit. Since this registers are handled during the load/unload routines, this cleanup is removed altogether.

This is a fix for bug, introduced in 3.4 kernel by commit 1ab5ecb9 ("tun: don't hold network namespace by tun sockets"), which, among other things, replaced simple sock_put() by sk_release_kernel(). Below is sequence, which leads to oops for non-persistent devices: tun_chr_close() tun_detach() <== tun->socket.file = NULL tun_free_netdev() sk_release_sock() sock_release(sock->file == NULL) iput(SOCK_INODE(sock)) <== dereference on NULL pointer This patch just removes zeroing of socket's file from __tun_detach(). sock_release() will do this.

Driver probe functions are generally __devinit so they will be discarded after initialization for non-hotplug kernels. This was found by a new warning after patch 6a228452 "stmmac: Add device-tree support" adds a new __devinit function that is called from stmmac_pltfr_probe. Without this patch, building socfpga_defconfig results in: WARNING: drivers/net/ethernet/stmicro/stmmac/stmmac.o(.text+0x5d4c): Section mismatch in reference from the function stmmac_pltfr_probe() to the function .devinit.text:stmmac_probe_config_dt() The function stmmac_pltfr_probe() references the function __devinit stmmac_probe_config_dt().

We allocate memory for 'req' with usb_alloc_urb() and then test 'if (!req || rx_submit(pnd, req, GFP_KERNEL | __GFP_COLD))'. If we enter that branch due to '!req' then there is no problem. But if we enter the branch due to 'req' being != 0 and the 'rx_submit()' call being false, then we'll leak the memory we allocated. Deal with the leak by always calling 'usb_free_urb(req)' when entering the branch. If 'req' happens to be 0 then the call is harmless, if it is not 0 then we free the memory we allocated but don't need.

[Resending again, as the text was corrupted by the email client] To speed up operations, QFQ internally divides classes into groups. Which group a class belongs to depends on the ratio between the maximum packet length and the weight of the class. Unfortunately the function qfq_change_class lacks the steps for changing the group of a class when the ratio max_pkt_len/weight of the class changes. For example, when the last of the following three commands is executed, the group of class 1:1 is not correctly changed: tc disc add dev XXX root handle 1: qfq tc class add dev XXX parent 1: qfq classid 1:1 weight 1 tc class change dev XXX parent 1: classid 1:1 qfq weight 4 Not changing the group of a class does not affect the long-term bandwidth guaranteed to the class, as the latter is independent of the maximum packet length, and correctly changes (only) if the weight of the class changes. In contrast, if the group of the class is not updated, the class is still guaranteed the short-term bandwidth and packet delay related to its old group, instead of the guarantees that it should receive according to its new weight and/or maximum packet length. This may also break service guarantees for other classes. This patch adds the missing operations. Signed-off-by: NPaolo Valente <paolo.valente@unimore.it> Signed-off-by: NDavid S.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu由 Linus Torvalds 提交于
Pull IOMMU fixes from Joerg Roedel: "These patches fix a couple of issues. First of all a few problems with ACS on x86 introduced in the last merge window, where ACS did not work on AMD and a NULL pointer dereference when there ran against SR-IOV devices. The patches fallen out of coccinelle checks fix a possible invalid memory reference and a possible memory leak. The other patches mostly fix build errors and warnings and a wrong return value." * tag 'iommu-fixes-v3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/amd: Fix ACS path checking iommu/intel: Fix ACS path checking iommu/amd: Fix pci_request_acs() call-place iommu/exynos: Fix build error iommu/tegra: smmu: Fix error initial value at domain_init iommu/tegra: smmu: Cleanup with lesser nest iommu: Add missing forward declaration in include file iommu: Include linux/types.h iommu/intel: add missing free_domain_mem iommu/tegra: remove invalid reference to list iterator variable

When CONFIG_SND_VERBOSE_PRINTK=y is set, the debug print in hda_auto_parser.c looks really ugly like: ALSA sound/pci/hda/hda_auto_parser.c:331 mono: mono_out=0x0 ALSA sound/pci/hda/hda_auto_parser.c:334 dig-out=0x12/0x0 ALSA sound/pci/hda/hda_auto_parser.c:335 inputs: ALSA sound/pci/hda/hda_auto_parser.c:339 Mic=0x11ALSA sound/pci/hda/hda_auto_parser.c:339 Line=0x10 ALSA sound/pci/hda/hda_auto_parser.c:341 ALSA sound/pci/hda/hda_auto_parser.c:343 dig-in=0x13 Better to put one item at each line.
