| | | | * rcutorture: Set KCSAN Kconfig options to detect more data racesPaul E. McKenney2020-02-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit enables the KCSAN Kconfig options that (1) detect data races between reads and writes even when the writes do not change the variable's value and (2) detect data races involving plain C-language writes. These changes only affect scripted rcutorture runs and can be overridden using the kvm.sh --kconfig argument. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
| | | | * rcutorture: Make kvm-find-errors.sh abort on bad directoryPaul E. McKenney2020-02-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, kvm-find-errors.sh gives a usage prompt when given a bad directory, but then soldiers on, giving a series of confusing error messages. This commit therefore prints an error message and exits when given a bad directory, hopefully reducing confusion. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
| | | | * rcutorture: Summarize summary of build and run resultsPaul E. McKenney2020-02-211-1/+16

But a run with something like "--configs '5*CFLIST'" will be 80 lines long, and it is all too easy to miss a failure message when scrolling back. This commit therefore prints out the number of runs with failing builds or runtime failures, but only if there are any such failures. For example, a run with a single build error and a single runtime error would print two lines like this: 1 runs with build errors. 1 runs with runtime errors. Signed-off-by: Paul E.

| | | | * rcutorture: Add 100-CPU configurationPaul E. McKenney2020-02-211-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The small-system rcutorture configurations have served us well for a great many years, but it is now time to add a larger one. This commit does just that, but does not add it to the defaults in CFLIST. This allows the kvm.sh argument '--configs "4*CFLIST TREE10" to run four instances of each of the default configurations concurrently with one instance of the large configuration.

| | | | * torture: Make results-directory date format completion-friendlyPaul E. McKenney2020-02-211-1/+1
| | | |/ | | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The names of the per-test results directories are of the form 2019.11.29-20:42:19. This works, but the ":" characters make tab-based shell name completion a bit onerous because the user must remember to include a quote character somewhere before the first ":". This commit therefore changes the ":" characters to periods, as in 2019.12.01-20.48.01", which allows tab-based completion to work more naturally. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bootparam_hotplug_cpu() bash function was checking for CPU-hotplug kernel-boot parameters from --bootargs, but that check was specific to rcutorture ("rcutorture\.onoff_"). This commit therefore makes this check also work for locktorture ("torture\.onoff_"). Note that rcuperf does not do CPU-hotplug operations, so it is not necessary to make a similar change for rcuperf. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

| * | | | firmware_loader: load files from the mount namespace of initTopi Miettinen2020-02-113-6/+158
| | |_|/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have an experimental setup where almost every possible system service (even early startup ones) runs in separate namespace, using a dedicated, minimal file system. In process of minimizing the contents of the file systems with regards to modules and firmware files, I noticed that in my system, the firmware files are loaded from three different mount namespaces, those of systemd-udevd, init and systemd-networkd. The logic of the source namespace is not very clear, it seems to depend on the driver, but the namespace of the current process is used. So, this patch tries to make things a bit clearer and changes the loading of firmware files only from the mount namespace of init. This may also improve security, though I think that using firmware files as attack vector could be too impractical anyway. Later, it might make sense to make the mount namespace configurable, for example with a new file in /proc/sys/kernel/firmware_config/. That would allow a dedicated file system only for firmware files and those need not be present anywhere else. This configurability would make more sense if made also for kernel modules and /sbin/modprobe. Modules are already loaded from init namespace (usermodehelper uses kthreadd namespace) except when directly loaded by systemd-udevd. Instead of using the mount namespace of the current process to load firmware files, use the mount namespace of init process.

The reason it was introduced is because TSYNC makes the syscall return a thread-id on failure, and NEW_LISTENER returns an fd, and there's no way to distinguish between these two cases (well, I suppose the caller could check all fds it has, then do the syscall, and if the return value was an fd that already existed, then it must be a thread id, but bleh). Matthew would like to use these two flags together in the Chrome sandbox which wants to use TSYNC for video drivers and NEW_LISTENER to proxy syscalls. So, let's fix this ugliness by adding another flag, TSYNC_ESRCH, which tells the kernel to just return -ESRCH on a TSYNC error. This way, NEW_LISTENER (and any subsequent seccomp() commands that want to return positive values) don't conflict with each other.

This test covers two recent fixes: 07f8e4d0fddb ("tcp: also NULL skb->dev when copy was needed") and b738a185beaa ("tcp: ensure skb->dev is NULL before leaving TCP stack"). 2) The fwd action breaks with ifb. For safety in next extensions, make sure the fwd action only runs from ingress until it is extended to be used from a different hook. 3) The pipapo set type now reports EEXIST in case of subrange overlaps.

Could be extended in the future to also cover serialization of conntrack, uid and secctx attributes in nfqueue. For now, this checks that 'queue bypass' works, that a queue rule with no bypass option blocks traffic and that userspace receives the expected number of packets. For this we add two queues and hook all of prerouting/input/forward/output/postrouting. Packets get queued twice with a dummy base chain in between: This passes with current nf tree, but reverting commit 946c0d8e6ed4 ("netfilter: nf_queue: fix reinject verdict handling") makes this trip (it processes 30 instead of expected 20 packets). v2: update config file with queue and other options missing/needed for other tests. v3: also test with tcp, this reveals problem with commit 28f8bfd1ac94 ("netfilter: Support iif matches in POSTROUTING"), due to skb->dev pointing at another skb in the retransmit rbtree (skb->dev aliases to rbnode child).

However, not all ECDH computations yield a contributory result. Prior, we were just not letting those peers be added to the interface. However, this creates a strange inconsistency, since it was still possible to add other weird points, like a valid public key plus a low-order point, and, like points that result in zeros, a handshake would not complete. In order to make the behavior more uniform and less surprising, simply allow all peers to be added. Then, we'll error out later when doing the crypto if there's an issue. This also adds more separation between the crypto layer and the configuration layer. Discussed-with: Mathias Hall-Andersen <mathias@hall-andersen.dk> Signed-off-by: Jason A.

However, the tests missed one such bug in the x32 JIT that is only uncovered when a previous instruction pollutes the upper 32 bits of the registers. This patch adds a new test case that catches the bug by first executing a 64-bit JSET to pollute the upper 32-bits of the temporary registers, followed by a 32-bit JSET which should ignore the upper 32 bits.

The reason for the default randconfig was because when this was first written, I wanted to do a bunch of randconfigs. But as time progressed, ktest isn't about randconfig anymore, and because randconfig destroys the config in the build directory, it's a dangerous default to have. Use oldconfig as the default.

While at it, define a convenient way to add these kind of tests, by adding a "reported issues" test section. It's more convenient, for this particular test, to execute the set setup in its own function. However, future test cases like this one might need to call setup functions, and will typically need no tools other than nft, so allow for this in check_tools().

For example the ftrace tests take multiple minutes to run, so they were given longer in commit b43e78f65b1d ("tracing/selftests: Turn off timeout setting"). This works when the tests are run from the source tree. However if the tests are installed with "make -C tools/testing/selftests install", the settings files are not copied into the install directory. When the tests are then run from the install directory the longer timeouts are not applied and the tests timeout incorrectly. So add the settings files to TEST_FILES of the appropriate Makefiles to cause the settings files to be installed using the existing install logic.
