When jiffies wraps around (for example, 5 minutes after the boot, see INITIAL_JIFFIES) and peer has just been created, now - peer->rate_last can be < XRLIM_BURST_FACTOR * timeout, so token is not set to the maximum value, thus some icmp packets can be unexpectedly dropped. Fix this case by initializing last_rate to 60 seconds in the past. Signed-off-by:

In the device close path, 'qlcnic_fw_destroy_ctx' and 'qlcnic_poll_rsp' call msleep. But 'qlcnic_fw_destroy_ctx' and 'qlcnic_poll_rsp' are called with 'adapter->tx_clean_lock' spin lock held resulting in scheduling while atomic bug causing the following trace. I observed that the commit 012dc19a from John Fastabend addresses a similar issue in ixgbevf driver. Adopting the same approach used in the commit, this patch uses mdelay to address the issue.

Commit d97b46a6 ("syscalls, x86: add __NR_kcmp syscall" ) added a new syscall to support checkpoint restore. It is currently x86-only, but that restriction will be removed in a subsequent patch. Unfortunately, the kernel checksyscalls script had a bug which suppressed any warning to other architectures that the kcmp syscall was not implemented. A patch to checksyscalls is being tested in linux-next and other architectures are seeing warnings about kcmp being unimplemented. This patch adds __NR_kcmp to <asm-generic/unistd.h> so that kcmp is wired in for architectures using the generic syscall list. Signed-off-by:

Pull more networking fixes from David Miller: 1) Eric Dumazet discovered and fixed what turned out to be a family of bugs. These functions were using pskb_may_pull() which might need to reallocate the linear SKB data buffer, but the callers were not expecting this possibility. The callers have cached pointers to the packet header areas, and would need to reload them if we were to continue using pskb_may_pull(). So they could end up reading garbage. It's easier to just change these RAW4/RAW6/MIP6 routines to use skb_header_pointer() instead of pskb_may_pull(), which won't modify the linear SKB data area. 2) Dave Jone's syscall spammer caught a case where a non-TCP socket can call down into the TCP keepalive code. The case basically involves creating a raw socket with sk_protocol == IPPROTO_TCP, then calling setsockopt(sock_fd, SO_KEEPALIVE, ...) Fixed by Eric Dumazet. 3) Bluetooth devices do not get configured properly while being powered on, resulting in always using legacy pairing instead of SSP. Fix from Andrzej Kaczmarek. 4) Bluetooth cancels delayed work erroneously, put stricter checks in place. From Andrei Emeltchenko. 5) Fix deadlock between cfg80211_mutex and reg_regdb_search_mutex in cfg80211, from Luis R. Rodriguez. 6) Fix interrupt double release in iwlwifi, from Emmanuel Grumbach. 7) Missing module license in bcm87xx driver, from Peter Huewe. 8) Team driver can lose port changed events when adding devices to a team, fix from Jiri Pirko. 9) Fix endless loop when trying ot unregister PPPOE device in zombie state, from Xiaodong Xu. 10) batman-adv layer needs to set MAC address of software device earlier, otherwise we call tt_local_add with it uninitialized. 11) Fix handling of KSZ8021 PHYs, it's matched currently by KS8051 but that doesn't program the device properly.

Commit 1ad75b9e ("c/r: prctl: add minimal address test to PR_SET_MM") added some address checking to prctl_set_mm() used by checkpoint-restore. This causes a build error for no-MMU systems: kernel/sys.c: In function 'prctl_set_mm': kernel/sys.c:1868:34: error: 'mmap_min_addr' undeclared (first use in this function) The test for mmap_min_addr doesn't make a lot of sense for no-MMU code as noted in commit 6e141546 ("NOMMU: Optimise away the {dac_,}mmap_min_addr tests"). This patch defines mmap_min_addr as 0UL in the no-MMU case so that the compiler will optimize away tests for "addr < mmap_min_addr". Signed-off-by:

When racing with CPU hotplug, percpu_counter_sum() can return negative values for the number of observed events. This confuses fprop_new_period(), which uses unsigned type and as a result number of events is set to big *positive* number. From that moment on, things go pear shaped and can result e.g. in division by zero as denominator is later truncated to 32-bits. This bug causes a divide-by-zero oops in bdi_dirty_limit() in Borislav's 3.6.0-rc6 based kernel. Fix the issue by using a signed type in fprop_new_period(). That makes us bail out from the function without doing anything (mistakenly) thinking there are no events to age. That makes aging somewhat inaccurate but getting accurate data would be rather hard.

Some drivers need to switch pin states between GPIO and pin function at runtime, which was inadvertently broken in the pinctrl driver for GPIOs being bound to a specific direction. This fixes up the request path to ensure that previously configured GPIOs don't cause us to inadvertently error out with an unsupported mux on reconfig, which in practice is primarily aimed at trapping pull-up/down users that have yet to be implemented under the new API. Fixes up regressions in the TPU PWM driver, amongst others. Reported-by:

John W. Linville says: ==================== Please pull this last(?) batch of fixes intended for 3.6... For the Bluetooth bits, Gustavo says this: "Here goes probably my last update to 3.6. It includes the two patches you were ok last week(from Andrzej Kaczmarek), those are critical ones, and two other fixes one for a system crash and the other for a missing lockdep annotation." The referenced fixes from Andrzej prevent attempts to configure devices that are powered-off. Along with the Bluetooth fixes, there are a couple of 802.11 fixes. Emmanuel Grumbach gives us an iwlwifi fix to prevent releasing an interrupt twice. Luis R. Rodriguez provides a fix for a possible circular lock dependency in the cfg80211 regulatory enforcement code. All of these have been in linux-next for a few days. I hope they are not too late to make the 3.6 release! ==================== Signed-off-by:

We end up in the situation where the initial domain gets too much information and gets confused and crashes - the fix is to restrict the domain to get the information - and we do it by just disabling NUMA on the PV guest (the hypervisor is still able to do its proper NUMA allocations of guests). It is OK to disable the PV guest from accessing NUMA data as right now we do not inject any NUMA node information to the PV guests. When we do get to that point, then this patch will have to be reverted." * Disable PV NUMA support as we do not do anything with it (yet) and it can cause bootup crashes on certain AMD machines. * tag 'stable/for-linus-3.6-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen/boot: Disable NUMA for PV guests.

In such case an reserved bit must be written in the 0x16, "Operation Mode Strap Override" register. According to the KS8051 datasheet, that bit means "PHY Address 0 in non-broadcast" and it indeed behaves as such on KSZ8021. The issue where the ethernet controller (Freescale FEC) did not communicate with network is fixed by writing this bit as 1. Signed-off-by:

An ABI numbering change was made in the hypervisor for Tilera's 4.1 MDE release (just shipped). It's incompatible with the previous 4.0 release ABI numbering, so we track the new numbering going forward. We plan to avoid modifying ABI numbering for these interfaces again. Signed-off-by:

A recent patch in the linux-next tree caused a build failure on C6X because C6X didn't define a read_barrier_depends() macro. C6X does not support SMP and the architecture doesn't provide any special memory ordering instructions, so it makes sense to just use the generic barrier.h rather than patching the existing c6x specific header.

The hypervisor is in charge of allocating the proper "NUMA" memory and dealing with the CPU scheduler to keep them bound to the proper NUMA node. The PV guests (and PVHVM) have no inkling of where they run and do not need to know that right now. In the future we will need to inject NUMA configuration data (if a guest spans two or more NUMA nodes) so that the kernel can make the right choices. But those patches are not yet present. In the meantime, disable the NUMA capability in the PV guest, which also fixes a bootup issue. Andre says: "we see Dom0 crashes due to the kernel detecting the NUMA topology not by ACPI, but directly from the northbridge (CONFIG_AMD_NUMA). This will detect the actual NUMA config of the physical machine, but will crash about the mismatch with Dom0's virtual memory. Variation of the theme: Dom0 sees what it's not supposed to see. This happens with the said config option enabled and on a machine where this scanning is still enabled (K8 and Fam10h, not Bulldozer class) We have this dump then: NUMA: Warning: node ids are out of bound, from=-1 to=-1 distance=10 Scanning NUMA topology in Northbridge 24 Number of physical nodes 4 Node 0 MemBase 0000000000000000 Limit 0000000040000000 Node 1 MemBase 0000000040000000 Limit 0000000138000000 Node 2 MemBase 0000000138000000 Limit 00000001f8000000 Node 3 MemBase 00000001f8000000 Limit 0000000238000000 Initmem setup node 0 0000000000000000-0000000040000000 NODE_DATA [000000003ffd9000 - 000000003fffffff] Initmem setup node 1 0000000040000000-0000000138000000 NODE_DATA [0000000137fd9000 - 0000000137ffffff] Initmem setup node 2 0000000138000000-00000001f8000000 NODE_DATA [00000001f095e000 - 00000001f0984fff] Initmem setup node 3 00000001f8000000-0000000238000000 Cannot find 159744 bytes in node 3 BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<ffffffff81d220e6>] __alloc_bootmem_node+0x43/0x96 Pid: 0, comm: swapper Not tainted 3.3.6 #1 AMD Dinar/Dinar RIP: e030:[<ffffffff81d220e6>] [<ffffffff81d220e6>] __alloc_bootmem_node+0x43/0x96 .. snip..

Pull kbuild fixes from Michal Marek: "There are two more kbuild fixes for 3.6. One fixes a race between x86's archscripts target and the rule (re)building scripts/basic/fixdep. The second is a fix for the previous attempt at fixing make firmware_install with make 3.82. This new solution should work with any version of GNU make" * 'rc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: x86/kbuild: archscripts depends on scripts_basic firmware: fix directory creation rule matching with make 3.80
