2023-01-12selftests: net: return non-zero for failures reported in ↵Po-Hsu Lin
arp_ndisc_evict_nocarrier [ Upstream commit 1856628baa17032531916984808d1bdfd62700d4 ] Return non-zero return value if there is any failure reported in this script during the test. Otherwise it can only reflect the status of the last command.

2023-01-12selftests: net: fix cleanup_v6() for arp_ndisc_evict_nocarrierPo-Hsu Lin
[ Upstream commit 9c4d7f45d60745a1cea0e841fa5e3444c398d2f1 ] The cleanup_v6() will cause the arp_ndisc_evict_nocarrier script exit with 255 (No such file or directory), even the tests are good: # selftests: net: arp_ndisc_evict_nocarrier.sh # run arp_evict_nocarrier=1 test # RTNETLINK answers: File exists # ok # run arp_evict_nocarrier=0 test # RTNETLINK answers: File exists # ok # run all.arp_evict_nocarrier=0 test # RTNETLINK answers: File exists # ok # run ndisc_evict_nocarrier=1 test # ok # run ndisc_evict_nocarrier=0 test # ok # run all.ndisc_evict_nocarrier=0 test # ok not ok 1 selftests: net: arp_ndisc_evict_nocarrier.sh # exit=255 This is because it's trying to modify the parameter for ipv4 instead. Also, tests for ipv6 (run_ndisc_evict_nocarrier_enabled() and run_ndisc_evict_nocarrier_disabled() are working on veth1, reflect this fact in cleanup_v6().

2023-01-07selftests: Use optional USERCFLAGS and USERLDFLAGSMickaël Salaün
commit de3ee3f63400a23954e7c1ad1cb8c20f29ab6fe3 upstream. This change enables to extend CFLAGS and LDFLAGS from command line, e.g. to extend compiler checks: make USERCFLAGS=-Werror USERLDFLAGS=-static USERCFLAGS and USERLDFLAGS are documented in Documentation/kbuild/makefiles.rst and Documentation/kbuild/kbuild.rst This should be backported (down to 5.10) to improve previous kernel versions testing as well.

2023-01-07ktest.pl minconfig: Unset configs instead of just removing themSteven Rostedt
commit ef784eebb56425eed6e9b16e7d47e5c00dcf9c38 upstream. After a full run of a make_min_config test, I noticed there were a lot of CONFIGs still enabled that really should not be. Looking at them, I noticed they were all defined as "default y". The issue is that the test simple removes the config and re-runs make oldconfig, which enables it again because it is set to default 'y'. Instead, explicitly disable the config with writing "# CONFIG_FOO is not set" to the file to keep it from being set again. With this change, one of my box's minconfigs went from 768 configs set, down to 521 configs set.

2023-01-07kest.pl: Fix grub2 menu handling for rebootingSteven Rostedt
commit 26df05a8c1420ad3de314fdd407e7fc2058cc7aa upstream. grub2 has submenus where to use grub-reboot, it requires: grub-reboot X>Y where X is the main index and Y is the submenu. Thus if you have: menuentry 'Debian GNU/Linux' --class debian --class gnu-linux ... [...] } submenu 'Advanced options for Debian GNU/Linux' $menuentry_id_option ... menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64' --class debian --class gnu-linux ... [...] } menuentry 'Debian GNU/Linux, with Linux 6.0.0-4-amd64 (recovery mode)' --class debian --class gnu-linux ... [...] } menuentry 'Debian GNU/Linux, with Linux test' --class debian --class gnu-linux ... [...] } And wanted to boot to the "Linux test" kernel, you need to run: # grub-reboot 1>2 As 1 is the second top menu (the submenu) and 2 is the third of the sub menu entries. Have the grub.cfg parsing for grub2 handle such cases.

2022-12-31netfilter: conntrack: set icmpv6 redirects as RELATEDFlorian Westphal
[ Upstream commit 7d7cfb48d81353e826493d24c7cec7360950968f ] icmp conntrack will set icmp redirects as RELATED, but icmpv6 will not do this. For icmpv6, only icmp errors (code <= 128) are examined for RELATED state. ICMPV6 Redirects are part of neighbour discovery mechanism, those are handled by marking a selected subset (e.g. neighbour solicitations) as UNTRACKED, but not REDIRECT -- they will thus be flagged as INVALID. Add minimal support for REDIRECTs. No parsing of neighbour options is added for simplicity, so this will only check that we have the embeeded original header (ND_OPT_REDIRECT_HDR), and then attempt to do a flow lookup for this tuple. Also extend the existing test case to cover redirects. Fixes: 9fb9cbb1082d ("[NETFILTER]: Add nf_conntrack subsystem.")

2022-12-14ipv4: Fix incorrect route flushing when table ID 0 is usedIdo Schimmel
[ Upstream commit c0d999348e01df03e0a7f550351f3907fabbf611 ] Cited commit added the table ID to the FIB info structure, but did not properly initialize it when table ID 0 is used. This can lead to a route in the default VRF with a preferred source address not being flushed when the address is deleted. Consider the following example: # ip address add dev dummy1 192.0.2.1/28 # ip address add dev dummy1 192.0.2.17/28 # ip route add 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 100 # ip route add table 0 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 200 # ip route show 198.51.100.0/24 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 100 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200 Both routes are installed in the default VRF, but they are using two different FIB info structures. One with a metric of 100 and table ID of 254 (main) and one with a metric of 200 and table ID of 0. Therefore, when the preferred source address is deleted from the default VRF, the second route is not flushed: # ip address del dev dummy1 192.0.2.17/28 # ip route show 198.51.100.0/24 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200 Fix by storing a table ID of 254 instead of 0 in the route configuration structure.

[ Upstream commit d5082d386eee7e8ec46fa8581932c81a4961dcef ] When the kernel receives a route deletion request from user space it tries to delete a route that matches the route attributes specified in the request. If only prefix information is specified in the request, the kernel should delete the first matching FIB alias regardless of its associated FIB info. However, an error is currently returned when the FIB info is backed by a nexthop object: # ip nexthop add id 1 via 192.0.2.2 dev dummy10 # ip route add 198.51.100.0/24 nhid 1 # ip route del 198.51.100.0/24 RTNETLINK answers: No such process Fix by matching on such a FIB info when legacy nexthop attributes are not specified in the request.

2022-11-26ksefltests: pidfd: Fix wait_states: Test terminated by timeoutLi Zhijian
[ Upstream commit 88e1f16ba58665e9edfce437ea487da2fa759af9 ] 0Day/LKP observed that the kselftest blocks forever since one of the pidfd_wait doesn't terminate in 1 of 30 runs. After digging into the source, we found that it blocks at: ASSERT_EQ(sys_waitid(P_PIDFD, pidfd, &info, WCONTINUED, NULL), 0); wait_states has below testing flow: CHILD PARENT ---------------+-------------- 1 STOP itself 2 WAIT for CHILD STOPPED 3 SIGNAL CHILD to CONT 4 CONT 5 STOP itself 5' WAIT for CHILD CONT 6 WAIT for CHILD STOPPED The problem is that the kernel cannot ensure the order of 5 and 5', once 5 goes first, the test will fail. we can reproduce it by: $ while true; do make run_tests -C pidfd; done Introduce a blocking read in child process to make sure the parent can check its WCONTINUED.

[ Upstream commit 03cab65a07e083b6c1010fbc8f9b817e9aca75d9 ] Don't use the test-specific header files as source files to force a target dependency, as clang will complain if more than one source file is used for a compile command with a single '-o' flag. Use the proper Makefile variables instead as defined in tools/testing/selftests/lib.mk.

2022-11-10selftests/landlock: Build without static librariesMickaël Salaün
commit 091873e47ef700e935aa80079b63929af599a0b2 upstream. The only (forced) static test binary doesn't depend on libcap. Because using -lcap on systems that don't have such static library would fail (e.g. on Arch Linux), let's be more specific and require only dynamic libcap linking.
