2014-01-23test: check copy_to/from_user boundary validationKees Cook
To help avoid an architecture failing to correctly check kernel/user boundaries when handling copy_to_user, copy_from_user, put_user, or get_user, perform some simple tests and fail to load if any of them behave unexpectedly. Specifically, this is to make sure there is a way to notice if things like what was fixed in commit 8404663f81d2 ("ARM: 7527/1: uaccess: explicitly check __user pointer when !CPU_USE_DOMAINS") ever regresses again, for any architecture. Additionally, adds new "user" selftest target, which loads this module.

They include: - add config to modify the signal to terminate console - update to documentation (missing some config options) - add KERNEL_VERSION variable to use for other configs - add '=~' to let configs eval other configs - add BISECT_TRIES to run multiple tests per git bisect good" * tag 'ktest-v3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest: ktest: Add BISECT_TRIES to bisect test ktest: Add eval '=~' command to modify variables in config file ktest: Add special variable ${KERNEL_VERSION} ktest: Add documentation of CLOSE_CONSOLE_SIGNAL ktest: Make the signal to terminate the console configurable
2014-01-18ktest: Add BISECT_TRIES to bisect testSteven Rostedt (Red Hat)
For those cases that it takes several tries to hit a bug, it would be useful for ktest.pl to try a test multiple times before it considers the test as a pass. To accomplish this, BISECT_TRIES ktest config option has been added. It is default to one, as most of the time a bisect only needs to try a test once. But the user can now up this to make ktest run a given test multiple times. The first failure that is detected will set a bisect bad. It only repeats on success. Note, as with all race bugs, there's no guarantee that if it succeeds, it is really a good bisect. But it helps in case the bug is somewhat reliable. You can set BISECT_TRIES to zero, and all tests will be considered good, unless you also set BISECT_MANUAL. Suggested-by: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2013-12-11ktest: Add eval '=~' command to modify variables in config fileSteven Rostedt (Red Hat)
With the added variable ${KERNEL_VERSION}, it is useful to be able to use parts of it for other variables. For example, if you want to create a warnings file for each major kernel version to test sub versions against you can create your warnings file with like this: WARNINGS_FILE = warnings-file-${KERNEL_VERSION} But this may add 3.8.12 or something, and we want all 3.8.* to use the same file, and 3.10.* to use another file, and so on. With the eval command we can, by adding: WARNINGS_FILE =~ s/(-file-\d+\.\d+).*/$1/ Which will chop off the extra characters after the 3.8. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2013-12-11ktest: Add special variable ${KERNEL_VERSION}Steven Rostedt (Red Hat)
Add a special variable that can be used in other variables called ${KERNEL_VERSION}. This will embed the current kernel version into the variable. For example: WARNINGS_FILE = ${OUTPUT_DIR}/warnings-${KERNEL_VERSION} If the current version is v3.8 then the WARNINGS_FILE will become ${OUTPUT_DIR}/warnings-v3.8 Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2013-12-03rcutorture: Stop tracking FSF's postal addressPaul E. McKenney
All of the rcutorture scripts has the usual GPL header, which contains a long-obsolete postal address for FSF. To avoid the need to track the FSF office's movements, this commit substitutes the URL where GPL may be found.

2013-12-03rcutorture: Flag errors and warnings with color codingPaul E. McKenney
The output of the rcutorture scripts often requires interpretation, so this commit simplifies this interpretation by tagging messages as BUGs (colored red) or WARNINGs (colored yellow).

2013-12-03rcutorture: Record results from repeated runs of the same test scenarioPaul E. McKenney
Repeatedly running a given test, for example, by repeating the name as in "--configs "TREE08 TREE08 TREE08" records the results only of the last run of this test. This is because the earlier results are overwritten by the later results. This commit therefore checks for earlier results, using numbered file extensions to distinguish multiple runs. The earlier example would therefore create directories TREE01, TREE01.2, and TREE01.3. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Cc: Greg KH <gregkh@linuxfoundation.org>
2013-12-03rcutorture: Test summary at end of run with less chattinessPaul E. McKenney

2013-12-03rcutorture: Add tracing-enabled version of TREE08Paul E. McKenney
The TREE08 Kconfig fragment does not enable tracing, which is appropriate for its test case. However, this can be inconvenient in cases where TREE08 locates RCU bugs. This commit therefore adds a TREE08-T that differs from TREE08 only in enabling CONFIG_RCU_TRACE. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Cc: Greg KH <gregkh@linuxfoundation.org>
2013-12-03rcutorture: Add --kmake-arg argument to kvm.shPaul E. McKenney
This commit adds the --kmake-arg to kvm.sh, which allows passing in things like "V=1" to see the build commands, as well as enabling the CROSS_COMPILE= make macro used for cross-building. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Cc: Greg KH <gregkh@linuxfoundation.org>
2013-12-03rcutorture: Add --no-initrd argument to kvm.shPaul E. McKenney
This commit adds the --no-initrd argument to kvm.sh, which permits initrd to be contained in a root partition specified by the --bootargs argument. Without --no-initrd, the kernel build expects an initrd directory in the same rcutorture directory that contains bin and configs. Signed-off-by: Paul E.

2013-12-03rcutorture: Refactor to enable non-x86 architecturesPaul E. McKenney

2013-12-03rcutorture: Eliminate --rcu-kvm argumentPaul E. McKenney
The --rcu-kvm argument was intended to allow the scripts to live in an alternate location. Unfortunately, this prevents the kvm.sh script from using common functions until after it finished parsing arguments, because it doesn't know where to find them until then. However, "cp -a" and "ln -s" work pretty well, so lack of an --rcu-kvm argument can be easily worked around. This commit therefore removes this argument. Signed-off-by: Paul E.

2013-12-03rcutorture: Abstract qemu-flavor identificationPaul E. McKenney
The task of working out which flavor of qemu to use gets more complex as more types of CPUs are supported. Adding Power makes three in addition to 32-bit and 64-bit x86, so it is time to pull this out into a function. This commit therefore creates an identify_qemu function and also adds a --qemu-cmd command-line argument for the inevitable case where the identify_qemu cannot figure it out. Signed-off-by: Paul E.

2013-12-03ktest: Make the signal to terminate the console configurableSatoru Takeuchi
Currently ktest sends SIGINT to terminate the console. However, there are consoles which do not exit by this signal, for example, in my case, "virsh console <guest OS>". In such case, ktest is blocked in close_console(). It prevents this automate test. This patch adds new option CLOSE_CONSOLE_SIGNAL which mean the signal to terminate the console. Since its default value is "INT", the original behavior isn't changed.

Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...
