2019-04-17selftests/kexec: update get_secureboot_modeMimi Zohar1-20/+66
The get_secureboot_mode() function unnecessarily requires both CONFIG_EFIVAR_FS and CONFIG_EFI_VARS to be enabled to determine if the system is booted in secure boot mode. On some systems the old EFI variable support is not enabled or, possibly, even implemented. This patch first checks the efivars filesystem for the SecureBoot and SetupMode flags, but falls back to using the old EFI variable support. The "secure_boot_file" and "setup_mode_file" couldn't be quoted due to globbing. This patch also removes the globbing.

It did not make sense to change the zero-key semantic in isolation for the "secure-erase" command, but instead include it for all security commands. The short background on the need for these changes is that some NVDIMM platforms enable security with a default zero-key rather than let the OS specify the initial key.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter updates for net-next: 1) Remove the broute pseudo hook, implement this from the bridge prerouting hook instead. Now broute becomes real table in ebtables, from Florian Westphal. This also includes a size reduction patch for the bridge control buffer area via squashing boolean into bitfields and a selftest. 2) Add OS passive fingerprint version matching, from Fernando Fernandez. 3) Support for gue encapsulation for IPVS, from Jacky Hu. 4) Add support for NAT to the inet family, from Florian Westphal. This includes support for masquerade, redirect and nat extensions. 5) Skip interface lookup in flowtable, use device in the dst object. 6) Add jiffies64_to_msecs() and use it, from Li RongQing. 7) Remove unused parameter in nf_tables_set_desc_parse(), from Colin Ian King. 8) Statify several functions, patches from YueHaibing and Florian Westphal. 9) Add an optimized version of nf_inet_addr_cmp(), from Li RongQing. 10) Merge route extension to core, also from Florian. 11) Use IS_ENABLED(CONFIG_NF_NAT) instead of NF_NAT_NEEDED, from Florian. 12) Merge ip/ip6 masquerade extensions, from Florian. This includes netdevice notifier unification. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2019-04-15netfilter: nat: fix icmp id randomizationFlorian Westphal1-9/+27
Sven Auhagen reported that a 2nd ping request will fail if 'fully-random' mode is used. Reason is that if no proto information is given, min/max are both 0, so we set the icmp id to 0 instead of chosing a random value between 0 and 65535. Update test case as well to catch this, without fix this yields: [..] ERROR: cannot ping ns1 from ns2 with ip masquerade fully-random (attempt 2) ERROR: cannot ping ns1 from ns2 with ipv6 masquerade fully-random (attempt 2) ... becaus 2nd ping clashes with existing 'id 0' icmp conntrack and gets dropped.

2019-04-13selftests: netfilter: check icmp pkttoobig errors are set as relatedFlorian Westphal2-1/+284
When an icmp error such as pkttoobig is received, conntrack checks if the "inner" header (header of packet that did not fit link mtu) is matches an existing connection, and, if so, sets that packet as being related to the conntrack entry it found. It was recently reported that this "related" setting also works if the inner header is from another, different connection (i.e., artificial/forged icmp error). Add a test, followup patch will add additional "inner dst matches outer dst in reverse direction" check before setting related state.

2019-04-12selftests/bpf: C based test for sysctl and strtoXAndrey Ignatov2-1/+126
Add C based test for a few bpf_sysctl_* helpers and bpf_strtoul. Make sure that sysctl can be identified by name and that multiple integers can be parsed from sysctl value with bpf_strtoul. net/ipv4/tcp_mem is chosen as a testing sysctl, it contains 3 unsigned longs, they all are parsed and compared (val[0] < val[1] < val[2]). Example of output: # ./test_sysctl ... Test case: C prog: deny all writes .. [PASS] Test case: C prog: deny access by name .. [PASS] Test case: C prog: read tcp_mem ..

2019-04-11selftests: Add debugging options to pmtu.shDavid Ahern1-89/+124
pmtu.sh script runs a number of tests and dumps a summary of pass/fail. If a test fails, it is near impossible to debug why. For example: TEST: ipv6: PMTU exceptions [FAIL] There are a lot of commands run behind the scenes for this test. Which one is failing? Add a VERBOSE option to show commands that are run and any output from those commands. Add a PAUSE_ON_FAIL option to halt the script if a test fails allowing users to poke around with the setup in the failed state. In the process, rename tracing to TRACING and move declaration to top with the new variables.
