Implement test that runs 5 instances of tc add filter in parallel with 5 instances of tc del filter from same tp instance. Each instance uses its own filter handle and key range. Extend tdc_multibatch.py with additional options required to implement the test: common prefix for all generated batch files, first value of filter handle range, MAC address prefix modifier. These are necessary to allow creating batch files with unique keys and handle ranges with multiple invocation of tdc_multibatch.py helper script.

2019-02-24selftests: concurrency: add test to verify concurrent deleteVlad Buslov
Implement test that verifies concurrent deletion of rules by executing 10 tc instances that delete flower filters in same handle range. In this case only one tc instance succeeds in deleting a filter with particular handle. To mitigate expected failures of all other instances, run tc with 'force' option to continue processing batch file in case of errors and expect xargs to return code '123' that indicates that invocation of command(s) exited with error in range 1-125.

2019-02-24selftests: tdc_batch.py: add options needed for concurrency testsVlad Buslov
Extend tdc_batch.py with several optional CLI arguments that are used for implementation of concurrency tests in following patches in this set: - Add optional argument to specify range of filter handles used in batch file [fitler_handle, filter_handle+number). This is needed for testing filter deletion where it is necessary to know exact handles of configured filters. - Add optional argument to specify filter operation type (possible values are ['add', 'del', 'replace']) instead of hardcoded "add" value. This allows generation of batches for filter addition, deletion and replacement. - Add optional argument to allow user to change mac address prefix that is used for all filters in batch. This is necessary to allow generating multiple batches with unique flower classifier keys. Signed-off-by: Vlad Buslov <vladbu@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Three conflicts, one of which, for marvell10g.c is non-trivial and requires some follow-up from Heiner or someone else. The issue is that Heiner converted the marvell10g driver over to use the generic c45 code as much as possible. However, in 'net' a bug fix appeared which makes sure that a new local mask (MDIO_AN_10GBT_CTRL_ADV_NBT_MASK) with value 0x01e0 is cleared. Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-23selftests: fib_tests: sleep after changing carrier. again.Thadeu Lima de Souza Cascardo
Just like commit e2ba732a1681 ("selftests: fib_tests: sleep after changing carrier"), wait one second to allow linkwatch to propagate the carrier change to the stack. There are two sets of carrier tests. The first slept after the carrier was set to off, and when the second set ran, it was likely that the linkwatch would be able to run again without much delay, reducing the likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a loop, you will quickly notice the failures. Sleeping on the second set of tests make the failures go away.

The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S.

git://git.infradead.org/users/jjs/linux-tpmdd into next-tpm tpmdd updates for Linux v5.1 From: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com> Clean up the transmission flow ============================== Cleaned up the whole transmission flow. Locking of the chip is now done in the level of tpm_try_get_ops() and tpm_put_ops() instead taking the chip lock inside tpm_transmit(). The nested calls inside tpm_transmit(), used with the resource manager, have been refactored out. Should make easier to perform more complex transactions with the TPM without making the subsystem a bigger mess (e.g. encrypted channel patches by James Bottomley). PPI 1.3 support =============== TPM PPI 1.3 introduces an additional optional command parameter that may be needed for some commands. Display the parameter if the command requires such a parameter. Only command 23 (SetPCRBanks) needs one. The PPI request file will show output like this then: # echo "23 16" > request # cat request 23 16 # echo "5" > request # cat request 5 Extend all PCR banks in IMA =========================== Instead of static PCR banks array, the array of available PCR banks is now allocated dynamically. The digests sizes are determined dynamically using a probe PCR read without relying crypto's static list of hash algorithms. This should finally make sealing of measurements in IMA safe and secure. TPM 2.0 selftests ================= Added a test suite to tools/testing/selftests/tpm2 previously outside of the kernel tree: https://github.com/jsakkine-intel/tpm2-scripts.

2019-02-12livepatch/selftests: use "$@" to preserve argument listJoe Lawrence
The livepatch selftest functions.sh library uses "$*" and an intermediate variable to extract and then pass arguments from function to function call. The effect of this combination is that the argument list is flattened into a single argument. Sometimes this is benign, but in cases like __load_mod(), the modprobe invocation will interpret all the module parameters as a single parameter. Drop the intermediate variable and use the "$@" special parameter as described in the bash manual.

2019-02-11selftests: bpf: relax sub-register mode compilation criteriaJiong Wang
Sub-register mode compilation was enabled only when there are eBPF "v3" processor supports at both compilation time inside LLVM and runtime inside kernel. Given separation betwen build and test server could be often, this patch removes the runtime support criteria.
