830ac85 Linus Torvalds 21 April 2013, 01:40:36 UTC Merge branch 'x86-kdump-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull kdump fixes from Peter Anvin: "The kexec/kdump people have found several problems with the support for loading over 4 GiB that was introduced in this merge cycle. This is partly due to a number of design problems inherent in the way the various pieces of kdump fit together (it is pretty horrifically manual in many places.) After a *lot* of iterations this is the patchset that was agreed upon, but of course it is now very late in the cycle. However, because it changes both the syntax and semantics of the crashkernel option, it would be desirable to avoid a stable release with the broken interfaces." I'm not happy with the timing, since originally the plan was to release the final 3.9 tomorrow. But apparently I'm doing an -rc8 instead... * 'x86-kdump-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: kexec: use Crash kernel for Crash kernel low x86, kdump: Change crashkernel_high/low= to crashkernel=,high/low x86, kdump: Retore crashkernel= to allocate under 896M x86, kdump: Set crashkernel_low automatically 21 April 2013, 01:40:36 UTC

83f1b4b Linus Torvalds 19 April 2013, 15:32:32 UTC net: fix incorrect credentials passing Commit 257b5358b32f ("scm: Capture the full credentials of the scm sender") changed the credentials passing code to pass in the effective uid/gid instead of the real uid/gid. Obviously this doesn't matter most of the time (since normally they are the same), but it results in differences for suid binaries when the wrong uid/gid ends up being used. This just undoes that (presumably unintentional) part of the commit. Reported-by: Andy Lutomirski <luto@amacapital.net> Cc: Eric W. Biederman <ebiederm@xmission.com> Cc: Serge E.

Peter Anvin 19 April 2013, 23:36:03 UTC x86, microcode: Verify the family before dispatching microcode patching For each CPU vendor that implements CPU microcode patching, there will be a minimum family for which this is implemented. Verify this minimum level of support. This can be done in the dispatch function or early in the application functions. Doing the latter turned out to be somewhat awkward because of the ineviable split between the BSP and the AP paths, and rather than pushing deep into the application functions, do this in the dispatch function.

b79d4a8 David S. Miller 19 April 2013, 21:51:26 UTC Merge branch 'qmi_wwan' Bjørn Mork says: ==================== This series adds workarounds for 3 different firmware bugs, each preventing the affected devices from working at all. I therefore humbly request that these fixes go to stable-3.8 (if still maintained) and 3.9 (either via net if still possible, or via stable if not). All 3 workarounds are applied to all devices supported by the driver. Adding quirks for specific devices was considered as an alternative, but was rejected because we have too little information about the exact distribution of the buggy firmwares. All we know is that the same bug shows up in devices from at least 3 different, and presumably independent, vendors. The workarounds have instead been designed to automatically apply when necessary, and to have as little impact as possible on unaffected devices. The series has been tested on a number of devices both with and without these bugs. The series should apply cleanly to net/master, net-next/master and stable/linux-3.8.y ==================== Signed-off-by: David S. Miller <davem@davemloft.net> 19 April 2013, 21:51:26 UTC

But some of these will erroneously list the address reserved for the device end of the link. Attempting to use this on both the device and host side will naturally not work.

It is likely a hardcoded firmware default. The circumstances where this bug has been observed indicates that the trigger is related to timing or some other factor the host cannot control. Repeating the exact same configuration sequence that caused it to trigger once, will not necessarily cause it to trigger the next time. Reproducing the bug is therefore difficult. This opens up a possibility that the bug is more common than we can confirm, because affected devices often will work properly again after a reset. A procedure most users are likely to try out before reporting a bug. Unconditionally rewriting the destination address if the first digit of the received packet is 0, is considered an acceptable compromise since we already have to inspect this digit. The simplification will cause unnecessary rewrites if the real address starts with 0, but this is still better than adding additional tests for this particular case.

6ff509a Bjørn Mork 18 April 2013, 12:57:09 UTC net: qmi_wwan: fixup missing ethernet header (firmware bug workaround) A number of LTE devices from different vendors all suffer from the same firmware bug: Most of the packets received from the device while it is attached to a LTE network will not have an ethernet header. The devices work as expected when attached to 2G or 3G networks, sending an ethernet header with all packets. This driver is not aware of which network the modem attached to, and even if it were there are still some packet types which are always received with the header intact. All devices supported by this driver have severely limited networking capabilities: - can only transmit IPv4, IPv6 and possibly ARP - can only support a single host hardware address at any time - will only do point-to-point communcation with the host Because of this, we are able to reliably identify any bogus raw IP packets by simply looking at the 4 IP version bits. All we need to do is to avoid 4 or 6 in the first digit of the mac address. This workaround ensures this, and fix up the received packets as necessary. Given the distribution of the bug, it is believed that the source is the chipset vendor. The devices which are verified to be affected are: Huawei E392u-12 (Qualcomm MDM9200) Pantech UML290 (Qualcomm MDM9600) Novatel USB551L (Qualcomm MDM9600) Novatel E362 (Qualcomm MDM9600) It is believed that the bug depend on firmware revision, which means that possibly all devices based on the above mentioned chipset may be affected if we consider all available firmware revisions. The information about affected devices and versions is likely incomplete. As the additional overhead for packets not needing this fixup is very small, it is considered acceptable to apply the workaround to all devices handled by this driver.

f36391d David S. Miller 19 April 2013, 21:26:26 UTC sparc64: Fix race in TLB batch processing. As reported by Dave Kleikamp, when we emit cross calls to do batched TLB flush processing we have a race because we do not synchronize on the sibling cpus completing the cross call. So meanwhile the TLB batch can be reset (tb->tlb_nr set to zero, etc.) and either flushes are missed or flushes will flush the wrong addresses. Fix this by using generic infrastructure to synchonize on the completion of the cross call. This first required getting the flush_tlb_pending() call out from switch_to() which operates with locks held and interrupts disabled. The problem is that smp_call_function_many() cannot be invoked with IRQs disabled and this is explicitly checked for with WARN_ON_ONCE(). We get the batch processing outside of locked IRQ disabled sections by using some ideas from the powerpc port. Namely, we only batch inside of arch_{enter,leave}_lazy_mmu_mode() calls. If we're not in such a region, we flush TLBs synchronously. 1) Get rid of xcall_flush_tlb_pending and per-cpu type implementations. 2) Do TLB batch cross calls instead via: smp_call_function_many() tlb_pending_func() __flush_tlb_pending() 3) Batch only in lazy mmu sequences: a) Add 'active' member to struct tlb_batch b) Define __HAVE_ARCH_ENTER_LAZY_MMU_MODE c) Set 'active' in arch_enter_lazy_mmu_mode() d) Run batch and clear 'active' in arch_leave_lazy_mmu_mode() e) Check 'active' in tlb_batch_add_one() and do a synchronous flush if it's clear. 4) Add infrastructure for synchronous TLB page flushes. a) Implement __flush_tlb_page and per-cpu variants, patch as needed. b) Likewise for xcall_flush_tlb_page. c) Implement smp_flush_tlb_page() to invoke the cross-call. d) Wire up global_flush_tlb_page() to the right routine based upon CONFIG_SMP 5) It turns out that singleton batches are very common, 2 out of every 3 batch flushes have only a single entry in them. The batch flush waiting is very expensive, both because of the poll on sibling cpu completeion, as well as because passing the tlb batch pointer to the sibling cpus invokes a shared memory dereference. Therefore, in flush_tlb_pending(), if there is only one entry in the batch perform a completely asynchronous global_flush_tlb_page() instead.

cea1509 Stephen Boyd 18 April 2013, 16:33:40 UTC ARM: 7699/1: sched_clock: Add more notrace to prevent recursion cyc_to_sched_clock() is called by sched_clock() and cyc_to_ns() is called by cyc_to_sched_clock(). I suspect that some compilers inline both of these functions into sched_clock() and so we've been getting away without having a notrace marking. It seems that my compiler isn't inlining cyc_to_sched_clock() though, so I'm hitting a recursion bug when I enable the function graph tracer, causing my system to crash. Marking these functions notrace fixes it. Technically cyc_to_ns() doesn't need the notrace because it's already marked inline, but let's just add it so that if we ever remove inline from that function it doesn't blow up.

During the manipulation required to release those resources, it's possible for the UNDI to try and write to memory regions which are no longer accessible, causing the PCI bus to prevent further writes from the chip. This would in turn cause DMAE timeouts later on in the driver, as the driver will be unable to use the chip's DMA engines. This patch prevents the chip from actually writing through the PCI bus in said scenario, thus allowing the release without the unfortunate by-product.

Use flush_cache_louis instead of flush_cache_all are that is sufficient to flush only the L1 data cache. flush_cache_louis did not exist when highbank_cpu_die was originally written.

This condition has not been met before 3.9-rc1 and doesn't trigger without this patch.

9cc3a5b Naoya Horiguchi 17 April 2013, 22:58:30 UTC hugetlbfs: add swap entry check in follow_hugetlb_page() With applying the previous patch "hugetlbfs: stop setting VM_DONTDUMP in initializing vma(VM_HUGETLB)" to reenable hugepage coredump, if a memory error happens on a hugepage and the affected processes try to access the error hugepage, we hit VM_BUG_ON(atomic_read(&page->_count) <= 0) in get_page(). The reason for this bug is that coredump-related code doesn't recognise "hugepage hwpoison entry" with which a pmd entry is replaced when a memory error occurs on a hugepage. In other words, physical address information is stored in different bit layout between hugepage hwpoison entry and pmd entry, so follow_hugetlb_page() which is called in get_dump_page() returns a wrong page from a given address. The expected behavior is like this: absent is_swap_pte FOLL_DUMP Expected behavior ------------------------------------------------------------------- true false false hugetlb_fault false true false hugetlb_fault false false false return page true false true skip page (to avoid allocation) false true true hugetlb_fault false false true return page With this patch, we can call hugetlb_fault() and take proper actions (we wait for migration entries, fail with VM_FAULT_HWPOISON_LARGE for hwpoisoned entries,) and as the result we can dump all hugepages except for hwpoisoned ones.

We have now modified crashkernel=X to allocate memory beyong 4G (if available) and do not allocate low range for crashkernel if the user does not specify that with crashkernel_low=Y. This causes regression if iommu is not enabled. Without iommu, swiotlb needs to be setup in first 4G and there is no low memory available to second kernel. Set crashkernel_low automatically if the user does not specify that. For system that does support IOMMU with kdump properly, user could specify crashkernel_low=0 to save that 72M low ram. -v3: add swiotlb_size() according to Konrad. -v4: add comments what 8M is for according to hpa. also update more crashkernel_low= in kernel-parameters.txt -v5: update changelog according to Vivek. -v6: Change description about swiotlb referring according to HATAYAMA.

Thus the L2 needs to be invalidated after both L1 caches are disabled. On kexec before the starting the code for relocation the kernel, the L1 caches are disabled in cpu_froc_fin (cpu_v7_proc_fin for Feroceon), but after L2 cache is never invalidated, because inv_all is not set in cache-feroceon-l2.c. So kernel relocation and decompression may has (and usually has) errors. Setting the function enables L2 invalidation and fixes the issue.

But if we reallocate the headroom of an SKB this can push the skb->csum_start value outside of it's valid range. This can easily happen when collapsing multiple SKBs from the retransmit queue together. Fix from Thomas Graf. 7) Fix NULL deref in be2net driver due to missing check of __vlan_put_tag() return value, from Ivan Vecera. 8) tun_set_iff() returns zero instead of error code on failure, fix from Wei Yongjun. 9) Like GARP, 802 MRP needs to hold the app->lock when adding MAD events and queueing PDUs. Fix from David Ward. 10) Build fix, MVMDIO needs PHYLIB, from Thomas Petazzoni.. 11) Fix mac80211 static with ipv6 modular build, from Cong Wang. 12) If userland specifies a path cost explicitly, do not override it when the carrier state changes. From Stephen Hemminger. 13) mvnets calculates the TX queue to use incorrectly resulting in garbage pointer derefs and crashes, fix from Willy Tarreau. 14) cdc_mbim does erroneous sizeof(ETH_HLEN). Fix from Bjorn Mork. 15) IP fragmentation can leak a refcount-less route out from an RCU protected section. This results in crashes and all sorts of hard to diagnose behavior. Fix from Eric Dumazet. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (24 commits) qlcnic: fix beaconing test for 82xx adapter net: drop dst before queueing fragments net: fec: fix regression in link change accounting net: cdc_mbim: remove bogus sizeof() drivers: net: ethernet: cpsw: get slave VLAN id from slave node instead of cpsw node net: mvneta: fix improper tx queue usage in mvneta_tx() esp4: fix error return code in esp_output() bridge: make user modified path cost sticky ipv6: statically link register_inet6addr_notifier() net: mvmdio: add select PHYLIB net/802/mrp: fix possible race condition when calling mrp_pdu_queue() tuntap: fix error return code in tun_set_iff() be2net: take care of __vlan_put_tag return value can: sja1000: fix handling on dt properties on little endian systems can: mcp251x: add missing IRQF_ONESHOT to request_threaded_irq netfilter: nf_nat: fix race when unloading protocol modules tcp: Reallocate headroom if it would overflow csum_start stmmac: prevent interrupt loop with MMC RX IPC Counter bonding: IFF_BONDING is not stripped on enslave failure bonding: fix netdev event NULL pointer dereference ... 17 April 2013, 15:50:59 UTC
4f2e290 Linus Torvalds 17 April 2013, 15:46:19 UTC s390: move dummy io_remap_pfn_range() to asm/pgtable.h Commit b4cbb197c7e7 ("vm: add vm_iomap_memory() helper function") added a helper function wrapper around io_remap_pfn_range(), and every other architecture defined it in <asm/pgtable.h>. The s390 choice of <asm/io.h> may make sense, but is not very convenient for this case, and gratuitous differences like that cause unexpected errors like this: mm/memory.c: In function 'vm_iomap_memory': mm/memory.c:2439:2: error: implicit declaration of function 'io_remap_pfn_range' [-Werror=implicit-function-declaration] Glory be the kbuild test robot who noticed this, bisected it, and reported it to the guilty parties (ie me).

The kernel build is self-contained and can be built on non-Linux toolchains. After the mentioned commit builds on non-Linux toolchains will try to include stdint.h and fail due to -nostdinc, and then fail with a bunch of undefined type errors. Fix by checking for __KERNEL__ instead of __linux__ and using the standard int types instead of the linux specific ones.

97599dc Eric Dumazet 16 April 2013, 12:55:41 UTC net: drop dst before queueing fragments Commit 4a94445c9a5c (net: Use ip_route_input_noref() in input path) added a bug in IP defragmentation handling, as non refcounted dst could escape an RCU protected section. Commit 64f3b9e203bd068 (net: ip_expire() must revalidate route) fixed the case of timeouts, but not the general problem. Tom Parkin noticed crashes in UDP stack and provided a patch, but further analysis permitted us to pinpoint the root cause. Before queueing a packet into a frag list, we must drop its dst, as this dst has limited lifetime (RCU protected) When/if a packet is finally reassembled, we use the dst of the very last skb, still protected by RCU and valid, as the dst of the reassembled packet. Use same logic in IPv6, as there is no need to hold dst references.
