The test depends on random numbers, and, based on them, # it sets different TM states. # # Other than that, the test fills out the user context struct that is # passed to the sigreturn system call with random data, in order to make # sure that the signal handler syscall can handle different and invalid # states properly. # # This selftest has command line parameters to control what kind of # tests the user wants to run, as for example, if a transaction should # be started prior to signal being raised, or, after the signal being # raised and before the sigreturn. If no parameter is given, the default # is enabling all options. # # This test does not check if the user context is being read and set # properly by the kernel. Its purpose, at this time, is basically # guaranteeing that the kernel does not crash on invalid scenarios. # # Signed-off-by: Breno Leitao <leitao@debian.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 83e367f9ad18d42a1883ee29f20608a2b93e1071 # < make -s -j 10 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_le_defconfig # make -s -j 10 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_le_defconfig_ppc64le-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- <stdin>:1478:2: warning: #warning syscall pidfd_send_signal not implemented [-Wcpp] <stdin>:1481:2: warning: #warning syscall io_uring_setup not implemented [-Wcpp] <stdin>:1484:2: warning: #warning syscall io_uring_enter not implemented [-Wcpp] <stdin>:1487:2: warning: #warning syscall io_uring_register not implemented [-Wcpp] /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1658:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg; ^ /kisskb/src/kernel/futex.c:1633:6: note: 'oldval' was declared here int oldval, ret; ^ /kisskb/src/net/netfilter/nf_nat_masquerade.c:15:21: warning: 'masq_refcnt6' defined but not used [-Wunused-variable] static unsigned int masq_refcnt6 __read_mostly; ^ WARNING: vmlinux.o(.text+0x340c): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init() The function __boot_from_prom() references the function __init prom_init().
