2014-09-17mnt: Add tests for unprivileged remount cases that have found to be faultyEric W. Biederman
commit db181ce011e3c033328608299cd6fac06ea50130 upstream. Kenton Varda <kenton@sandstorm.io> discovered that by remounting a read-only bind mount read-only in a user namespace the MNT_LOCK_READONLY bit would be cleared, allowing an unprivileged user to the remount a read-only mount read-write. Upon review of the code in remount it was discovered that the code allowed nosuid, noexec, and nodev to be cleared. It was also discovered that the code was allowing the per mount atime flags to be changed. The first naive patch to fix these issues contained the flaw that using default atime settings when remounting a filesystem could be disallowed. To avoid this problems in the future add tests to ensure unprivileged remounts are succeeding and failing at the appropriate times. Acked-by: Serge E.

2014-04-10gator-daemon: Fix compilation error: 'sa_family_t' does not name a typeJon Medhurst
When compiling on Linaro Android we get the following error: bionic/libc/kernel/common/linux/netlink.h:52:2: error: 'sa_family_t' does not name a type sa_family_t nl_family; This is related to an issue that was fixed in Linux 3.1 by commit 6602a4baf4d1a73c (net: Make userland include of netlink.h more sane) but it seems that the Linux headers used by bionic predate that. Fortunately, the fix for us is simple: reorder the header file includes so that the definition of sa_family_t from sys/socket.h is picked up before being used by linux/netlink.h Signed-off-by: Jon Medhurst <tixy@linaro.org>

2014-02-13turbostat: Use GCC's CPUID functions to support PICJosh Triplett
commit 2b92865e648ce04a39fda4f903784a5d01ecb0dc upstream. turbostat uses inline assembly to call cpuid. On 32-bit x86, on systems that have certain security features enabled by default that make -fPIC the default, this causes a build error: turbostat.c: In function ‘check_cpuid’: turbostat.c:1906:2: error: PIC register clobbered by ‘ebx’ in ‘asm’ asm("cpuid" : "=a" (fms), "=c" (ecx), "=d" (edx) : "a" (1) : "ebx"); ^ GCC provides a header cpuid.h, containing a __get_cpuid function that works with both PIC and non-PIC. (On PIC, it saves and restores ebx around the cpuid instruction.) Use that instead.

2014-02-13turbostat: Don't put unprocessed uapi headers in the include pathJosh Triplett
commit b731f3119de57144e16c19fd593b8daeb637843e upstream. turbostat's Makefile puts arch/x86/include/uapi/ in the include path, so that it can include <asm/msr.h> from it. It isn't in general safe to include even uapi headers directly from the kernel tree without processing them through scripts/headers_install.sh, but asm/msr.h happens to work. However, that include path can break with some versions of system headers, by overriding some system headers with the unprocessed versions directly from the kernel source. For instance: In file included from /build/x86-generic/usr/include/bits/sigcontext.h:28:0, from /build/x86-generic/usr/include/signal.h:339, from /build/x86-generic/usr/include/sys/wait.h:31, from turbostat.c:27: ../../../../arch/x86/include/uapi/asm/sigcontext.h:4:28: fatal error: linux/compiler.h: No such file or directory This occurs because the system bits/sigcontext.h on that build system includes <asm/sigcontext.h>, and asm/sigcontext.h in the kernel source includes <linux/compiler.h>, which scripts/headers_install.sh would have filtered out. Since turbostat really only wants a single header, just include that one header rather than putting an entire directory of kernel headers on the include path. In the process, switch from msr.h to msr-index.h, since turbostat just wants the MSR numbers.

2014-02-06perf kvm: Fix kvm report without guestmount.Dongsheng Yang
commit ad85ace07a05062ef6b59c35a5e80b6eaee1eee6 upstream. Currently, if we use perf kvm --guestkallsyms --guestmodules report, we can not get the perf information from perf data file. All sample are shown as unknown. Reproducing steps: # perf kvm --guestkallsyms /tmp/kallsyms --guestmodules /tmp/modules record -a sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.624 MB perf.data.guest (~27260 samples) ] # perf kvm --guestkallsyms /tmp/kallsyms --guestmodules /tmp/modules report |grep % 100.00% [guest/6471] [unknown] [g] 0xffffffff8164f330 This bug was introduced by 207b57926 (perf kvm: Fix regression with guest machine creation). In original code, it uses perf_session__find_machine(), it means we deliver symbol to machine which has the same pid, if no machine found, deliver it to *default* guest. But if we use perf_session__findnew_machine() here, if no machine was found, new machine with pid will be built and added. Then the default guest which with pid == 0 will never get a symbol. And because the new machine initialized here has no kernel map created, the symbol delivered to it will be marked as "unknown". This patch here is to revert commit 207b57926 and fix the SEGFAULT bug in another way. Verification steps: # ./perf kvm --guestkallsyms /home/kallsyms --guestmodules /home/modules record -a sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.651 MB perf.data.guest (~28437 samples) ] # ./perf kvm --guestkallsyms /home/kallsyms --guestmodules /home/modules report |grep % 22.64% :6471 [guest.kernel.kallsyms] [g] update_rq_clock.part.70 19.99% :6471 [guest.kernel.kallsyms] [g] d_free 18.46% :6471 [guest.kernel.kallsyms] [g] bio_phys_segments 16.25% :6471 [guest.kernel.kallsyms] [g] dequeue_task 12.78% :6471 [guest.kernel.kallsyms] [g] __switch_to 7.91% :6471 [guest.kernel.kallsyms] [g] scheduler_tick 1.75% :6471 [guest.kernel.kallsyms] [g] native_apic_mem_write 0.21% :6471 [guest.kernel.kallsyms] [g] apic_timer_interrupt Signed-off-by: Dongsheng Yang <yangds.fnst@cn.fujitsu.com> Acked-by: David Ahern <dsahern@gmail.com> Cc: David Ahern <dsahern@gmail.com> Link: http://lkml.kernel.org/r/1387564907-3045-1-git-send-email-yangds.fnst@cn.fujitsu.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit f447ef4a56dee4b68a91460bcdfe06b5011085f2 upstream. If a user calls 'cpupower set --perf-bias 15', the process will end with a SIGSEGV in libc because cpupower-set passes a NULL optarg to the atoi call. This is because the getopt_long structure currently has all of the options as having an optional_argument when they really have a required argument. We change the structure to use required_argument to match the short options and it resolves the issue.

2013-08-04perf tools: Revert regression in configuration of Python supportMichael Witten
commit a363a9da65d253fa7354ce5fd630f4f94df934cc upstream. Among other things, the following: commit 31160d7feab786c991780d7f0ce2755a469e0e5e Date: Tue Jan 8 16:22:36 2013 -0500 perf tools: Fix GNU make v3.80 compatibility issue attempts to aid the user by tapping into an existing error message, as described in the commit message: ... Also fix an issue where _get_attempt was called with only one argument. This prevented the error message from printing the name of the variable that can be used to fix the problem. or more precisely: -$(if $($(1)),$(call _ge_attempt,$($(1)),$(1)),$(call _ge_attempt,$(2))) +$(if $($(1)),$(call _ge_attempt,$($(1)),$(1)),$(call _ge_attempt,$(2),$(1))) However, The "missing" argument was in fact missing on purpose; it's absence is a signal that the error message should be skipped, because the failure would be due to the default value, not any user-supplied value. This can be seen in how `_ge_attempt' uses `gea_err' (in the config/utilities.mak file): _ge_attempt = $(if $(get-executable),$(get-executable),$(_gea_warn)$(call _gea_err,$(2))) _gea_warn = $(warning The path '$(1)' is not executable.) _gea_err = $(if $(1),$(error Please set '$(1)' appropriately)) That is, because the argument is no longer missing, the value `$(1)' (associated with `_gea_err') always evaluates to true, thus always triggering the error condition that is meant to be reserved for only the case when a user explicitly supplies an invalid value. Concretely, the result is a regression in the Makefile's configuration of python support; rather than gracefully disable support when the relevant executables cannot be found according to default values, the build process halts in error as though the user explicitly supplied the values. This new commit simply reverts the offending one-line change.

Plus I dived into lguest again, reworking the pagetable code so we can move the switcher page: our fixmaps sometimes take more than 2MB now..." Ugh. Annoying conflicts with the tcm_vhost -> vhost_scsi rename. Hopefully correctly resolved. * tag 'virtio-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux: (57 commits) caif_virtio: Remove bouncing email addresses lguest: improve code readability in lg_cpu_start. virtio-net: fill only rx queues which are being used lguest: map Switcher below fixmap. lguest: cache last cpu we ran on. lguest: map Switcher text whenever we allocate a new pagetable. lguest: don't share Switcher PTE pages between guests. lguest: expost switcher_pages array (as lg_switcher_pages). lguest: extract shadow PTE walking / allocating. lguest: make check_gpte et. al return bool. lguest: assume Switcher text is a single page. lguest: rename switcher_page to switcher_pages. lguest: remove RESERVE_MEM constant. lguest: check vaddr not pgd for Switcher protection. lguest: prepare to make SWITCHER_ADDR a variable. virtio: console: replace EMFILE with EBUSY for already-open port virtio-scsi: reset virtqueue affinity when doing cpu hotplug virtio-scsi: introduce multiqueue support virtio-scsi: push vq lock/unlock into virtscsi_vq_done virtio-scsi: pass struct virtio_scsi to virtqueue completion function ...

Pull networking updates from David Miller: "Highlights (1721 non-merge commits, this has to be a record of some sort): 1) Add 'random' mode to team driver, from Jiri Pirko and Eric Dumazet. 2) Make it so that any driver that supports configuration of multiple MAC addresses can provide the forwarding database add and del calls by providing a default implementation and hooking that up if the driver doesn't have an explicit set of handlers. From Vlad Yasevich. 3) Support GSO segmentation over tunnels and other encapsulating devices such as VXLAN, from Pravin B Shelar. 4) Support L2 GRE tunnels in the flow dissector, from Michael Dalton. 5) Implement Tail Loss Probe (TLP) detection in TCP, from Nandita Dukkipati. 6) In the PHY layer, allow supporting wake-on-lan in situations where the PHY registers have to be written for it to be configured. Use it to support wake-on-lan in mv643xx_eth. From Michael Stapelberg. 7) Significantly improve firewire IPV6 support, from YOSHIFUJI Hideaki. 8) Allow multiple packets to be sent in a single transmission using network coding in batman-adv, from Martin Hundebøll. 9) Add support for T5 cxgb4 chips, from Santosh Rastapur. 10) Generalize the VXLAN forwarding tables so that there is more flexibility in configurating various aspects of the endpoints. From David Stevens. 11) Support RSS and TSO in hardware over GRE tunnels in bxn2x driver, from Dmitry Kravkov. 12) Zero copy support in nfnelink_queue, from Eric Dumazet and Pablo Neira Ayuso. 13) Start adding networking selftests. 14) In situations of overload on the same AF_PACKET fanout socket, or per-cpu packet receive queue, minimize drop by distributing the load to other cpus/fanouts. From Willem de Bruijn and Eric Dumazet. 15) Add support for new payload offset BPF instruction, from Daniel Borkmann. 16) Convert several drivers over to mdoule_platform_driver(), from Sachin Kamat. 17) Provide a minimal BPF JIT image disassembler userspace tool, from Daniel Borkmann. 18) Rewrite F-RTO implementation in TCP to match the final specification of it in RFC4138 and RFC5682. From Yuchung Cheng. 19) Provide netlink socket diag of netlink sockets ("Yo dawg, I hear you like netlink, so I implemented netlink dumping of netlink sockets.") From Andrey Vagin. 20) Remove ugly passing of rtnetlink attributes into rtnl_doit functions, from Thomas Graf. 21) Allow userspace to be able to see if a configuration change occurs in the middle of an address or device list dump, from Nicolas Dichtel. 22) Support RFC3168 ECN protection for ipv6 fragments, from Hannes Frederic Sowa. 23) Increase accuracy of packet length used by packet scheduler, from Jason Wang. 24) Beginning set of changes to make ipv4/ipv6 fragment handling more scalable and less susceptible to overload and locking contention, from Jesper Dangaard Brouer. 25) Get rid of using non-type-safe NLMSG_* macros and use nlmsg_*() instead. From Hong Zhiguo. 26) Optimize route usage in IPVS by avoiding reference counting where possible, from Julian Anastasov. 27) Convert IPVS schedulers to RCU, also from Julian Anastasov. 28) Support cpu fanouts in xt_NFQUEUE netfilter target, from Holger Eitzenberger. 29) Network namespace support for nf_log, ebt_log, xt_LOG, ipt_ULOG, nfnetlink_log, and nfnetlink_queue. From Gao feng. 30) Implement RFC3168 ECN protection, from Hannes Frederic Sowa. 31) Support several new r8169 chips, from Hayes Wang. 32) Support tokenized interface identifiers in ipv6, from Daniel Borkmann. 33) Use usbnet_link_change() helper in USB net driver, from Ming Lei. 34) Add 802.1ad vlan offload support, from Patrick McHardy. 35) Support mmap() based netlink communication, also from Patrick McHardy. 36) Support HW timestamping in mlx4 driver, from Amir Vadai. 37) Rationalize AF_PACKET packet timestamping when transmitting, from Willem de Bruijn and Daniel Borkmann. 38) Bring parity to what's provided by /proc/net/packet socket dumping and the info provided by netlink socket dumping of AF_PACKET sockets. From Nicolas Dichtel. 39) Fix peeking beyond zero sized SKBs in AF_UNIX, from Benjamin Poirier" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1722 commits) filter: fix va_list build error af_unix: fix a fatal race with bit fields bnx2x: Prevent memory leak when cnic is absent bnx2x: correct reading of speed capabilities net: sctp: attribute printl with __printf for gcc fmt checks netlink: kconfig: move mmap i/o into netlink kconfig netpoll: convert mutex into a semaphore netlink: Fix skb ref counting. net_sched: act_ipt forward compat with xtables mlx4_en: fix a build error on 32bit arches Revert "bnx2x: allow nvram test to run when device is down" bridge: avoid OOPS if root port not found drivers: net: cpsw: fix kernel warn on cpsw irq enable sh_eth: use random MAC address if no valid one supplied 3c509.c: call SET_NETDEV_DEV for all device types (ISA/ISAPnP/EISA) tg3: fix to append hardware time stamping flags unix/stream: fix peeking with an offset larger than data in queue unix/dgram: fix peeking with an offset larger than data in queue unix/dgram: peek beyond 0-sized skbs openvswitch: Remove unneeded ovs_netdev_get_ifindex() ...
