2023-06-16KVM: s390: selftests: add selftest for CMMA migrationNico Boehr2-0/+701
Add a selftest for CMMA migration on s390. The tests cover: - interaction of dirty tracking and migration mode, see my recent patch "KVM: s390: disable migration mode when dirty tracking is disabled" [1], - several invalid calls of KVM_S390_GET_CMMA_BITS, for example: invalid flags, CMMA support off, with/without peeking - ensure KVM_S390_GET_CMMA_BITS initally reports all pages as dirty, - ensure KVM_S390_GET_CMMA_BITS properly skips over holes in memslots, but also non-dirty pages Note that without the patch at [1] and the small fix in this series, the selftests will fail.

The vrf-xfrm-tests tests use the hmac(md5) and cbc(des3_ede) algorithms for performing authentication and encryption, respectively. This causes the tests to fail when fips=1 is set, since these algorithms are not allowed in FIPS mode. Therefore, switch from hmac(md5) and cbc(des3_ede) to hmac(sha1) and cbc(aes), which are FIPS compliant.

Before executing each test from a fixture, FIXTURE_SETUP is run once. When SKIP is used in FIXTURE_SETUP, the setup function returns early but the test still proceeds to run, unless another SKIP macro is used within the test definition, leading to some code repetition. Therefore, allow tests to be skipped directly from the setup function.

On ICL, only the TopdownL1 should be displayed. Add a flag so we can tag the default metric group for different platforms rather than hack the perf code.

2023-06-15perf srcline: Fix handling of inline functionsIan Rogers1-56/+80
We write an address then a ',' to addr2line. With inline data we generally get back (// are my comments): 0x1234 // address foo // function name foo.c:123 // filename:line bar // function name bar.c:123 // filename:line 0x000000000000000 // sentinel address created by ',' ?? // unknown function name ??:0 // unknown filename:line The code was assuming the inline data also had the address, which is incorrect. This means the first inline function name (bar above) needs to be checked to see if it is the sentinel, otherwise to be treated as a function name. The regression was caused by the addition of addresses as the kernel is reporting a symbol at address 0 (used by GNU binutils when it interprets ',').

2023-06-15tools: ynl: work around stale system headersJakub Kicinski3-3/+35
The inability to include the uAPI headers directly in tools/ is one of the bigger annoyances of compiling user space code. Most projects trade the pain for smaller inconvenience of having to copy the headers under tools/include. In case of netlink headers I think that we can avoid both. Netlink family headers are simple and should be self-contained. We can try to twiddle the Makefile a little to force-include just the family header, and use system headers for the rest. This works fairly well. There are two warts - for some reason if we specify -include $path/family.h as a compilation flag, the #ifdef header guard does not seem to work. So we need to throw the guard in on the command line as well. Seems like GCC detects that the header is different and tries to include both. Second problem is that make wants hash sign to be escaped or not depending on the version. Sigh. Signed-off-by: Jakub Kicinski <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2023-06-14perf srcline: Add a timeout to reading from addr2lineIan Rogers3-4/+14
addr2line may fail to send expected values causing perf to wait indefinitely. Add a 1 second timeout (twice the timeout for reading from /proc/pid/maps) so that such reads don't cause perf to appear to lock up. There are already checks that the file for addr2line contains a debug section but this isn't always sufficient. The problem was observed when a valid elf file would set the configuration for binutils addr2line, then a later read of vmlinux with ELF debug sections would cause a failing write/read which would block indefinitely. As a service to future readers, if the io hits eof or an error, cleanup the addr2line process.

2023-06-14selftests: forwarding: hw_stats_l3: Set addrgenmode in a separate stepDanielle Ratson1-4/+7
Setting the IPv6 address generation mode of a net device during its creation never worked, but after commit b0ad3c179059 ("rtnetlink: call validate_linkmsg in rtnl_create_link") it explicitly fails [1]. The failure is caused by the fact that validate_linkmsg() is called before the net device is registered, when it still does not have an 'inet6_dev'. Likewise, raising the net device before setting the address generation mode is meaningless, because by the time the mode is set, the address has already been generated. Therefore, fix the test to first create the net device, then set its IPv6 address generation mode and finally bring it up.

Running shellcheck -S on daemon.sh throws below warnings: Result from shellcheck: # shellcheck -S warning daemon.sh local line_name=`echo "${line}" | awk 'BEGIN { FS = ":" } ; { print $2 }'` ^-------^ SC2155: Declare and assign separately to avoid masking return values. trap "echo 'FAILED: Signal caught'; daemon_exit ${config}; exit 1" SIGINT SIGTERM ^-------^ SC2064: Use single quotes, otherwise this expands now rather than when signalled. count=`ls ${base}/session-test/ | grep perf.data | wc -l` ^-- SC2010: Don't use ls | grep. Use a glob or a for loop with a condition to allow non-alphanumeric filenames. if [ ${size} != "OK" -o ${type} != "OK" ]; then ^-- SC2166: Prefer [ p ] || [ q ] as [ p -o q ] is not well defined. Fixed above warnings by: - declaring and assigning local variables separately - To fix SC2010, instead of using "ls | grep", used glob to allow non-alphanumeric filenames - Used single quotes to prevent expanding.
