2022-03-16bpf: selftests: Add helpers to directly use the capget and capset syscallMartin KaFai Lau
After upgrading to the newer libcap (>= 2.60), the libcap commit aca076443591 ("Make cap_t operations thread safe.") added a "__u8 mutex;" to the "struct _cap_struct". It caused a few byte shift that breaks the assumption made in the "struct libcap" definition in test_verifier.c. The bpf selftest usage only needs to enable and disable the effective caps of the running task. It is easier to directly syscall the capget and capset instead. It can also remove the libcap library dependency. The cap_helpers.{c,h} is added. One __u64 is used for all CAP_* bits instead of two __u32.

2022-03-15net: Add l3mdev index to flow struct and avoid oif reset for port devicesDavid Ahern
The fundamental premise of VRF and l3mdev core code is binding a socket to a device (l3mdev or netdev with an L3 domain) to indicate L3 scope. Legacy code resets flowi_oif to the l3mdev losing any original port device binding. Ben (among others) has demonstrated use cases where the original port device binding is important and needs to be retained. This patch handles that by adding a new entry to the common flow struct that can indicate the l3mdev index for later rule and table matching avoiding the need to reset flowi_oif. In addition to allowing more use cases that require port device binds, this patch brings a few datapath simplications: 1. l3mdev_fib_rule_match is only called when walking fib rules and always after l3mdev_update_flow. That allows an optimization to bail early for non-VRF type uses cases when flowi_l3mdev is not set. Also, only that index needs to be checked for the FIB table id. 2. l3mdev_update_flow can be called with flowi_oif set to a l3mdev (e.g., VRF) device. By resetting flowi_oif only for this case the FLOWI_FLAG_SKIP_NH_OIF flag is not longer needed and can be removed, removing several checks in the datapath. The flowi_iif path can be simplified to only be called if the it is not loopback (loopback can not be assigned to an L3 domain) and the l3mdev index is not already set. 3. Avoid another device lookup in the output path when the fib lookup returns a reject failure. Note: 2 functional tests for local traffic with reject fib rules are updated to reflect the new direct failure at FIB lookup time for ping rather than the failure on packet path. The current code fails like this: HINT: Fails since address on vrf device is out of device scope COMMAND: ip netns exec ns-A ping -c1 -w1 -I eth1 172.16.3.1 ping: Warning: source address might be selected on device other than: eth1 PING 172.16.3.1 (172.16.3.1) from 172.16.3.1 eth1: 56(84) bytes of data. --- 172.16.3.1 ping statistics --- 1 packets transmitted, 0 received, 100% packet loss, time 0ms where the test now directly fails: HINT: Fails since address on vrf device is out of device scope COMMAND: ip netns exec ns-A ping -c1 -w1 -I eth1 172.16.3.1 ping: connect: No route to host Signed-off-by: David Ahern <dsahern@kernel.org> Tested-by: Ben Greear <greearb@candelatech.com> Link: https://lore.kernel.org/r/20220314204551.16369-1-dsahern@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for net coming late in the 5.17-rc process: 1) Revert port remap to mitigate shadowing service ports, this is causing problems in existing setups and this mitigation can be achieved with explicit ruleset, eg. ... tcp sport < 16386 tcp dport >= 32768 masquerade random This patches provided a built-in policy similar to the one described above. 2) Disable register tracking infrastructure in nf_tables. Florian reported two issues: - Existing expressions with no implemented .reduce interface that causes data-store on register should cancel the tracking. - Register clobbering might be possible storing data on registers that are larger than 32-bits. This might lead to generating incorrect ruleset bytecode. These two issues are scheduled to be addressed in the next release cycle. * git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nf_tables: disable register tracking Revert "netfilter: conntrack: tag conntracks picked up in local out hook" Revert "netfilter: nat: force port remap to prevent shadowing well-known ports" ==================== Link: https://lore.kernel.org/r/20220312220315.64531-1-pablo@netfilter.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-03-14KVM: s390: selftests: Add macro as abstraction for MEM_OPJanis Schoetterl-Glausch
In order to achieve good test coverage we need to be able to invoke the MEM_OP ioctl with all possible parametrizations. However, for a given test, we want to be concise and not specify a long list of default values for parameters not relevant for the test, so the readers attention is not needlessly diverted. Add a macro that enables this and convert the existing test to use it. The macro emulates named arguments and hides some of the ioctl's redundancy, e.g. sets the key flag if an access key is specified.

2022-03-11nvdimm/blk: Delete the block-aperture window driverDan Williams
Block Aperture Window support was an attempt to layer an error model over PMEM for platforms that did not support machine-check-recovery. However, it was abandoned before it ever shipped, and only ever existed in the ACPI specification. Meanwhile Linux has carried a large pile of dead code for non-shipping infrastructure. For years it has been off to the side out of the way, but now CXL and recent directions with DAX support have the potential to collide with this code. In preparation for adding discontiguous namespace support, a pre-requisite for the nvdimm subsystem to replace device-mapper for striping + concatenation use cases, delete BLK aperture support. On the obscure chance that some hardware vendor shipped support for this mode, note that the driver will still keep BLK space reserved in the label area. So an end user in this case would still have the opportunity to report the regression to get BLK-mode support restored without risking the data they have on that device.

2022-03-11selftests/bpf: Fix a clang compilation error for send_signal.cYonghong Song
Building selftests/bpf with latest clang compiler (clang15 built from source), I hit the following compilation error: /.../prog_tests/send_signal.c:43:16: error: variable 'j' set but not used [-Werror,-Wunused-but-set-variable] volatile int j = 0; ^ 1 error generated. The problem also exists with clang13 and clang14. clang12 is okay. In send_signal.c, we have the following code ... volatile int j = 0; [...] for (int i = 0; i < 100000000 && !sigusr1_received; i++) j /= i + 1; ... to burn CPU cycles so bpf_send_signal() helper can be tested in NMI mode. Slightly changing 'j /= i + 1' to 'j /= i + j + 1' or 'j++' can fix the problem. Further investigation indicated this should be a clang bug ([1]). The upstream fix will be proposed later. But it is a good idea to workaround the issue to unblock people who build kernel/selftests with clang.

2022-03-10selftests: mptcp: join: make it shellcheck compliantMatthieu Baerts
This fixes a few issues reported by ShellCheck: - SC2068: Double quote array expansions to avoid re-splitting elements. - SC2206: Quote to prevent word splitting/globbing, or split robustly with mapfile or read -a. - SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined. - SC2155: Declare and assign separately to avoid masking return values. - SC2162: read without -r will mangle backslashes. - SC2219: Instead of 'let expr', prefer (( expr )) . - SC2181: Check exit code directly with e.g. 'if mycmd;', not indirectly with $?. - SC2236: Use -n instead of ! -z. - SC2004: $/${} is unnecessary on arithmetic variables. - SC2012: Use find instead of ls to better handle non-alphanumeric filenames. - SC2002: Useless cat. Consider 'cmd < file | ..' or 'cmd file | ..' instead. SC2086 (Double quotes to prevent globbing and word splitting) is ignored because it is controlled for the moment and there are too many to change. While at it, also fixed the alignment in one comment.

2022-03-10selftests: mptcp: join: clarify local/global varsMatthieu Baerts
Some vars are redefined in different places. Best to avoid this classical Bash pitfall where variables are accidentally overridden by other functions because the proper scope has not been defined. Most issues are with loops: typically 'i' is used in for-loops but if it is not global, calling a function from a for-loop also doing a for-loop with the same non local 'i' variable causes troubles because the first 'i' will be assigned to another value. To prevent such issues, the iterator variable is now declared as local just before the loop. If it is always done like this, issues are avoided. To distinct between local and non local variables, all non local ones are defined at the beginning of the script. The others are now defined with the "local" keyword.

2022-03-10selftests: mptcp: join: alt. to exec specific testsMatthieu Baerts
Running a specific test by giving the ID is often what we want: the CI reports an issue with the Nth test, it is reproducible with: ./mptcp_join.sh N But this might not work when there is a need to find which commit has introduced a regression making a test unstable: failing from time to time. Indeed, a specific test is not attached to one ID: the ID is in fact a counter. It means the same test can have a different ID if other tests have been added/removed before this unstable one. Remembering the current test can also help listing failed tests at the end.

2022-03-10selftests: mptcp: join: option to execute specific testsMatthieu Baerts
Often, it is needed to run one specific test. There are options to run subgroups of tests but when only one fails, no need to run all the subgroup. So far, the solution was to edit the script to comment the tests that are not needed but that's not ideal. Now, it is possible to run one specific test by giving the ID of the tests that are going to be validated, e.g. ./mptcp_join.sh 36 37 This is cleaner and saves time. Technically, the reset* functions now return 0 if the test can be executed. This naturally creates sections per test in the code which is also helpful to understand what a test is exactly doing.

2022-03-10selftests: mptcp: join: define tests groups onceMatthieu Baerts
When adding a new tests group, it has to be defined in multiple places: - in the all_tests() function - in the 'usage()' function - in the getopts: short option + what to do when the option is used Because it is easy to forget one of them, it is useful to have to define them only once. Note: only using an associative array would simplify the code but the entries are stored in a hashtable and iterating over the different items doesn't give the same order as the one used in the declaration of this array. Because we want to run these tests in the same order as before, a "simple" array is used first.

2022-03-09selftests: pmtu.sh: Kill nettest processes launched in subshell.Guillaume Nault
When using "run_cmd <command> &", then "$!" refers to the PID of the subshell used to run <command>, not the command itself. Therefore nettest_pids actually doesn't contain the list of the nettest commands running in the background. So cleanup() can't kill them and the nettest processes run until completion (fortunately they have a 5s timeout). Fix this by defining a new command for running processes in the background, for which "$!" really refers to the PID of the command run. Also, double quote variables on the modified lines, to avoid shellcheck warnings.

2022-03-09selftests: pmtu.sh: Kill tcpdump processes launched by subshell.Guillaume Nault
The cleanup() function takes care of killing processes launched by the test functions. It relies on variables like ${tcpdump_pids} to get the relevant PIDs. But tests are run in their own subshell, so updated *_pids values are invisible to other shells. Therefore cleanup() never sees any process to kill: $ ./tools/testing/selftests/net/pmtu.sh -t pmtu_ipv4_exception TEST: ipv4: PMTU exceptions [ OK ] TEST: ipv4: PMTU exceptions - nexthop objects [ OK ] $ pgrep -af tcpdump 6084 tcpdump -s 0 -i veth_A-R1 -w pmtu_ipv4_exception_veth_A-R1.pcap 6085 tcpdump -s 0 -i veth_R1-A -w pmtu_ipv4_exception_veth_R1-A.pcap 6086 tcpdump -s 0 -i veth_R1-B -w pmtu_ipv4_exception_veth_R1-B.pcap 6087 tcpdump -s 0 -i veth_B-R1 -w pmtu_ipv4_exception_veth_B-R1.pcap 6088 tcpdump -s 0 -i veth_A-R2 -w pmtu_ipv4_exception_veth_A-R2.pcap 6089 tcpdump -s 0 -i veth_R2-A -w pmtu_ipv4_exception_veth_R2-A.pcap 6090 tcpdump -s 0 -i veth_R2-B -w pmtu_ipv4_exception_veth_R2-B.pcap 6091 tcpdump -s 0 -i veth_B-R2 -w pmtu_ipv4_exception_veth_B-R2.pcap 6228 tcpdump -s 0 -i veth_A-R1 -w pmtu_ipv4_exception_veth_A-R1.pcap 6229 tcpdump -s 0 -i veth_R1-A -w pmtu_ipv4_exception_veth_R1-A.pcap 6230 tcpdump -s 0 -i veth_R1-B -w pmtu_ipv4_exception_veth_R1-B.pcap 6231 tcpdump -s 0 -i veth_B-R1 -w pmtu_ipv4_exception_veth_B-R1.pcap 6232 tcpdump -s 0 -i veth_A-R2 -w pmtu_ipv4_exception_veth_A-R2.pcap 6233 tcpdump -s 0 -i veth_R2-A -w pmtu_ipv4_exception_veth_R2-A.pcap 6234 tcpdump -s 0 -i veth_R2-B -w pmtu_ipv4_exception_veth_R2-B.pcap 6235 tcpdump -s 0 -i veth_B-R2 -w pmtu_ipv4_exception_veth_B-R2.pcap Fix this by running cleanup() in the context of the test subshell. Now that each test cleans the environment after completion, there's no need for calling cleanup() again when the next test starts. So let's drop it from the setup() function. This is okay because cleanup() is also called when pmtu.sh starts, so even the first test starts in a clean environment. Also, use tcpdump's immediate mode. Otherwise it might not have time to process buffered packets, resulting in missing packets or even empty pcap files for short tests. Note: PAUSE_ON_FAIL is still evaluated before cleanup(), so one can still inspect the test environment upon failure when using -p.
