2020-12-01kunit: kunit_tool: Correctly parse diagnostic messagesDavid Gow
Currently, kunit_tool expects all diagnostic lines in test results to contain ": " somewhere, as both the subtest header and the crash report do. Fix this to accept any line starting with (minus indent) "# " as being a valid diagnostic line. This matches what the TAP spec[1] and the draft KTAP spec[2] are expecting.

2020-11-30selftests/bpf: Fix flavored variants of test_imaKP Singh
Flavored variants of test_progs (e.g. test_progs-no_alu32) change their working directory to the corresponding subdirectory (e.g. no_alu32). Since the setup script required by test_ima (ima_setup.sh) is not mentioned in the dependencies, it does not get copied to these subdirectories and causes flavored variants of test_ima to fail. Adding the script to TRUNNER_EXTRA_FILES ensures that the file is also copied to the subdirectories for the flavored variants of test_progs.

2020-11-30ktest.pl: Fix the logic for truncating the size of the log file for emailSteven Rostedt (VMware)
The logic for truncating the log file for emailing based on the MAIL_MAX_SIZE option is confusing and incorrect. Simplify it and have the tail of the log file truncated to the max size specified in the config.

2020-11-30ktest.pl: If size of log is too big to email, email error messageSteven Rostedt (VMware)
If the size of the error log is too big to send via email, and the sending fails, it wont email any result. This can be confusing for the user who is waiting for an email on the completion of the tests. If it fails to send email, then try again without the log file stating that it failed to send an email. Obviously this will not be of use if the sending of email failed for some other reasons, but it will at least give the user some information when it fails for the most common reason.

2020-11-30ktest.pl: Fix incorrect reboot for grub2blsLibo Chen
This issue was first noticed when I was testing different kernels on Oracle Linux 8 which as Fedora 30+ adopts BLS as default. Even though a kernel entry was added successfully and the index of that kernel entry was retrieved correctly, ktest still wouldn't reboot the system into user-specified kernel. The bug was spotted in subroutine reboot_to where the if-statement never checks for REBOOT_TYPE "grub2bls", therefore the desired entry will not be set for the next boot. Add a check for "grub2bls" so that $grub_reboot $grub_number can be run before a reboot if REBOOT_TYPE is "grub2bls" then we can boot to the correct kernel.

2020-11-27libbpf: Replace size_t with __u32 in xsk interfacesMagnus Karlsson
Replace size_t with __u32 in the xsk interfaces that contain this. There is no reason to have size_t since the internal variable that is manipulated is a __u32. The following APIs are affected: __u32 xsk_ring_prod__reserve(struct xsk_ring_prod *prod, __u32 nb, __u32 *idx) void xsk_ring_prod__submit(struct xsk_ring_prod *prod, __u32 nb) __u32 xsk_ring_cons__peek(struct xsk_ring_cons *cons, __u32 nb, __u32 *idx) void xsk_ring_cons__cancel(struct xsk_ring_cons *cons, __u32 nb) void xsk_ring_cons__release(struct xsk_ring_cons *cons, __u32 nb) The "nb" variable and the return values have been changed from size_t to __u32.

2020-11-27KVM: arm64: selftests: Filter out DEMUX registersAndrew Jones
DEMUX register presence depends on the host's hardware (the CLIDR_EL1 register to be precise). This means there's no set of them that we can bless and that it's possible to encounter new ones when running on different hardware (which would generate "Consider adding them ..." messages, but we'll never want to add them.) Remove the ones we have in the blessed list and filter them out of the new list, but also provide a new command line switch to list them if one so desires.

2020-11-27perf probe: Change function definition check due to broken DWARFMasami Hiramatsu
Since some gcc generates a broken DWARF which lacks DW_AT_declaration attribute from the subprogram DIE of function prototype. (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97060) So, in addition to the DW_AT_declaration check, we also check the subprogram DIE has DW_AT_inline or actual entry pc.
