usbnet should centrally handle busy reporting in the rx path so subdrivers need not worry. This hurts use cases which do rx only or predominantly. Signed-off-by:

The following patch aimed to resolve an issue where secondary, tertiary, etc. addresses added to bond interfaces could overwrite the bond->master_ip and vlan_ip values. commit 917fbdb3 Author: Henrik Saavedra Persson <henrik.e.persson@ericsson.com> Date: Wed Nov 23 23:37:15 2011 +0000 bonding: only use primary address for ARP That patch was good because it prevented bonds using ARP monitoring from sending frames with an invalid source IP address. Unfortunately, it didn't always work as expected. When using an ioctl (like ifconfig does) to set the IP address and netmask, 2 separate ioctls are actually called to set the IP and netmask if the mask chosen doesn't match the standard mask for that class of address. The first ioctl did not have a mask that matched the one in the primary address and would still cause the device address to be overwritten. The second ioctl that was called to set the mask would then detect as secondary and ignored, but the damage was already done. This was not an issue when using an application that used netlink sockets as the setting of IP and netmask came down at once. The inconsistent behavior between those two interfaces was something that needed to be resolved. While I was thinking about how I wanted to resolve this, Ralf Zeidler came with a patch that resolved this on a RHEL kernel by keeping a full shadow of the entries in dev->ifa_list for the bonding device and vlan devices in the bonding driver. I didn't like the duplication of the list as I want to see the 'bonding' struct and code shrink rather than grow, but liked the general idea. As the Subject indicates this patch drops the master_ip and vlan_ip elements from the 'bonding' and 'vlan_entry' structs, respectively. This can be done because a device's address-list is now traversed to determine the optimal source IP address for ARP requests and for checks to see if the bonding device has a particular IP address. This code could have all be contained inside the bonding driver, but it made more sense to me to EXPORT and call inet_confirm_addr since it did exactly what was needed. I tested this and a backported patch and everything works as expected. Ralf also helped with verification of the backported patch. Thanks to Ralf for all his help on this. v2: Whitespace and organizational changes based on suggestions from Jay Vosburgh and Dave Miller. v3: Fixup incorrect usage of rcu_read_unlock based on Dave Miller's suggestion.

It used to be an int, and it got changed to a bool parameter at least 7 years ago. It happens that NF_ACCEPT and NF_DROP are 0 and 1, so this works, but it's unclear, and the check that it's in range is not required. Reported-by:

URB unlinking is always racing with its completion and tx_complete may be called before or during running usb_unlink_urb, so tx_complete must not clear urb->dev since it will be used in unlink path, otherwise invalid memory accesses or usb device leak may be caused inside usb_unlink_urb.

Commit 4231d47e(net/usbnet: avoid recursive locking in usbnet_stop()) fixes the recursive locking problem by releasing the skb queue lock, but it makes usb_unlink_urb racing with defer_bh, and the URB to being unlinked may be freed before or during calling usb_unlink_urb, so use-after-free problem may be triggerd inside usb_unlink_urb. The patch fixes the use-after-free problem by increasing URB reference count with skb queue lock held before calling usb_unlink_urb, so the URB won't be freed until return from usb_unlink_urb.

We should be using the gfp flags the caller specified here, instead of GFP_KERNEL. I think this might be a bugfix, depending on the value of "sock->sk->sk_allocation" when we call rds_conn_create_outgoing() in rds_sendmsg(). Otherwise, it's just a cleanup. Signed-off-by:

This function takes a GFP flags as a parameter, but they are never used. We don't take a lock in this function so there is no reason to prefer GFP_ATOMIC over the caller's GFP flags. There is only one caller, cipso_v4_map_cat_rng_ntoh(), and it passes GFP_ATOMIC as the GFP flags so this doesn't change how the code works. It's just a cleanup. Signed-off-by:

The RSS feature in tg3 hardware has only one rx producer ring for all RSS rings. NAPI vector 1 is special and handles the refilling of the rx producer ring on behalf of all RSS rings. There is a race condition between these RSS NAPIs and the NAPI[1]. If NAPI[1] finishes checking for refill and then another RSS ring empties the rx producer ring before NAPI[1] exits NAPI, the chip will be completely out of SKBs in the rx producer ring. We fix this by adding a flag tp->rx_refill and rely on napi_schedule()/ napi_complete() to help synchronize it to close the race condition. Update driver version to 3.123. Signed-off-by:

Pull irq_domain support for all architectures from Grant Likely: "Generialize powerpc's irq_host as irq_domain This branch takes the PowerPC irq_host infrastructure (reverse mapping from Linux IRQ numbers to hardware irq numbering), generalizes it, renames it to irq_domain, and makes it available to all architectures. Originally the plan has been to create an all-new irq_domain implementation which addresses some of the powerpc shortcomings such as not handling 1:1 mappings well, but doing that proved to be far more difficult and invasive than generalizing the working code and refactoring it in-place. So, this branch rips out the 'new' irq_domain and replaces it with the modified powerpc version (in a fully bisectable way of course). It converts all users over to the new API and makes irq_domain selectable on any architecture. No architecture is forced to enable irq_domain, but the infrastructure is required for doing OpenFirmware style irq translations. It will even work on SPARC even though SPARC has it's own mechanism for translating irqs at boot time. MIPS, microblaze, embedded x86 and c6x are converted too. The resulting irq_domain code is probably still too verbose and can be optimized more, but that can be done incrementally and is a task for follow-on patches." * tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux-2.6: (31 commits) dt: fix twl4030 for non-dt compile on x86 mfd: twl-core: Add IRQ_DOMAIN dependency devicetree: Add empty of_platform_populate() for !CONFIG_OF_ADDRESS (sparc) irq_domain: Centralize definition of irq_dispose_mapping() irq_domain/mips: Allow irq_domain on MIPS irq_domain/x86: Convert x86 (embedded) to use common irq_domain ppc-6xx: fix build failure in flipper-pic.c and hlwd-pic.c irq_domain/microblaze: Convert microblaze to use irq_domains irq_domain/powerpc: Replace custom xlate functions with library functions irq_domain/powerpc: constify irq_domain_ops irq_domain/c6x: Use library of xlate functions irq_domain/c6x: constify irq_domain structures irq_domain/c6x: Convert c6x to use generic irq_domain support. irq_domain: constify irq_domain_ops irq_domain: Create common xlate functions that device drivers can use irq_domain: Remove irq_domain_add_simple() irq_domain: Remove 'new' irq_domain in favour of the ppc one mfd: twl-core.c: Fix the number of interrupts managed by twl4030 of/address: add empty static inlines for !CONFIG_OF irq_domain: Add support for base irq and hwirq in legacy mappings ...

Minor cleanup. de_thread()->setmax_mm_hiwater_rss() looks a bit strange, move it into exec_mmap() which plays with old_mm. Signed-off-by:

exit_notify() changes ->exit_signal if the parent already did exec. This doesn't really work, we are not going to send the signal now if there is another live thread or the exiting task is traced. The parent can exec before the last dies or the tracer detaches. Move this check into do_notify_parent() which actually sends the signal. The user-visible change is that we do not change ->exit_signal, and thus the exiting task is still "clone children" for do_wait()->eligible_child(__WCLONE). Hopefully this is fine, the current logic is racy anyway. Signed-off-by:

exit_notify() checks "tsk->self_exec_id != tsk->parent_exec_id" to handle the "we have changed execution domain" case. We can change do_thread() to always set ->exit_signal = SIGCHLD and remove this check to simplify the code. We could change setup_new_exec() instead, this looks more logical because it increments ->self_exec_id. But note that de_thread() already resets ->exit_signal if it changes the leader, let's keep both changes close to each other. Note that we change ->exit_signal lockless, this changes the rules. Thereafter ->exit_signal is not stable under tasklist but this is fine, the only possible change is OLDSIG -> SIGCHLD. This can race with eligible_child() but the race is harmless. We can race with reparent_leader() which changes our ->exit_signal in parallel, but it does the same change to SIGCHLD. The noticeable user-visible change is that the execing task is not "visible" to do_wait()->eligible_child(__WCLONE) right after exec. To me this looks more logical, and this is consistent with mt case. Signed-off-by:

The child must not control its ->exit_signal, it is the parent who decides which signal the child should use for notification. This means that CLONE_PARENT should not use "clone_flags & CSIGNAL", the forking task is the sibling of the new process and their parent doesn't control exit_signal in this case. This patch uses ->exit_signal of the forking process, but perhaps we should simply use SIGCHLD. We read group_leader->exit_signal lockless, this can race with the ORIGINAL_SIGNAL -> SIGCHLD transition, but this is fine. Potentially this change allows to kill self_exec_id/parent_exec_id.

While testing L2TP functionality, I came across a bug in getsockname(). The IP address returned within the pppol2tp_addr's addr memember was not being set to the IP address in use. This bug is caused by using inet_sk() on the wrong socket (the L2TP socket rather than the underlying UDP socket), and was likely introduced during the addition of L2TPv3 support. Signed-off-by:
