Slowly those # have been fixed when the oopses have been tracked down. # # This set of changes fixes the remaining abusers of force_sig and # carefully rips out the task parameter from force_sig and friends # making this kind of error almost impossible in the future" # # * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (27 commits) # signal/x86: Move tsk inside of CONFIG_MEMORY_FAILURE in do_sigbus # signal: Remove the signal number and task parameters from force_sig_info # signal: Factor force_sig_info_to_task out of force_sig_info # signal: Generate the siginfo in force_sig # signal: Move the computation of force into send_signal and correct it. # signal: Properly set TRACE_SIGNAL_LOSE_INFO in __send_signal # signal: Remove the task parameter from force_sig_fault # signal: Use force_sig_fault_to_task for the two calls that don't deliver to current # signal: Explicitly call force_sig_fault on current # signal/unicore32: Remove tsk parameter from __do_user_fault # signal/arm: Remove tsk parameter from __do_user_fault # signal/arm: Remove tsk parameter from ptrace_break # signal/nds32: Remove tsk parameter from send_sigtrap # signal/riscv: Remove tsk parameter from do_trap # signal/sh: Remove tsk parameter from force_sig_info_fault # signal/um: Remove task parameter from send_sigtrap # signal/x86: Remove task parameter from send_sigtrap # signal: Remove task parameter from force_sig_mceerr # signal: Remove task parameter from force_sig # signal: Remove task parameter from force_sigsegv # ... # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 5ad18b2e60b75c7297a998dea702451d33a052ed # < make -s -j 24 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- randconfig KCONFIG_SEED=0x4104DD51 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # yes \n \| make -s -j 24 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 24 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c: In function 'sh_mobile_i2c_isr': /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:399:26: warning: 'data' may be used uninitialized in this function [-Wmaybe-uninitialized] pd->msg->buf[real_pos] = data; ^ /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:372:16: note: 'data' was declared here unsigned char data; ^ In file included from /kisskb/src/include/linux/rwsem.h:16:0, from /kisskb/src/include/linux/notifier.h:15, from /kisskb/src/include/linux/clk.h:14, from /kisskb/src/drivers/tty/serial/sh-sci.c:24: /kisskb/src/drivers/tty/serial/sh-sci.c: In function 'sci_dma_rx_submit': /kisskb/src/include/linux/spinlock.h:288:3: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized] _raw_spin_unlock_irqrestore(lock, flags); \ ^ /kisskb/src/drivers/tty/serial/sh-sci.c:1353:16: note: 'flags' was declared here unsigned long flags; ^ Completed OK # rm -rf /kisskb/build/linus-rand_x86_64-randconfig_um-x86_64 # Build took: 0:05:05.635485
