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 # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 83e367f9ad18d42a1883ee29f20608a2b93e1071 # < make -s -j 10 ARCH=powerpc O=/kisskb/build/powerpc-next_wii_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- wii_defconfig # make -s -j 10 ARCH=powerpc O=/kisskb/build/powerpc-next_wii_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- :1478:2: warning: #warning syscall pidfd_send_signal not implemented [-Wcpp] :1481:2: warning: #warning syscall io_uring_setup not implemented [-Wcpp] :1484:2: warning: #warning syscall io_uring_enter not implemented [-Wcpp] :1487:2: warning: #warning syscall io_uring_register not implemented [-Wcpp] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2594:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1855:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:121:34: warning: 'levelspread[]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:88:6: note: 'levelspread[]' was declared here /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:187:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:337:21: note: 'pdeo' was declared here /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1658:3: warning: 'oldval' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/futex.c:1633:6: note: 'oldval' was declared here /kisskb/src/drivers/net/wireless/broadcom/b43/phy_n.c: In function 'b43_nphy_rf_ctl_override_rev7': /kisskb/src/drivers/net/wireless/broadcom/b43/phy_n.c:203:21: warning: 'val_addr' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/mlme.c: In function 'ieee80211_rx_mgmt_beacon': /kisskb/src/net/mac80211/mlme.c:1581:3: warning: 'pwr_level_cisco' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/mlme.c:1538:6: note: 'pwr_level_cisco' was declared here WARNING: vmlinux.o(.text+0x11eec): Section mismatch in reference from the function setup_kup() to the function .init.text:setup_kuep() The function setup_kup() references the function __init setup_kuep().
