If a # ftrace_ops is registered to ftrace with the PERMANENT flag set, it # will prevent ftrace_enabled from being disabled, and if # ftrace_enabled is already disabled, it will prevent a ftrace_ops # with PREMANENT flag set from being registered. # # - New register_ftrace_direct(). # # As eBPF would like to register its own trampolines to be called by # the ftrace nop locations directly, without going through the ftrace # trampoline, this function has been added. This allows for eBPF # trampolines to live along side of ftrace, perf, kprobe and live # patching. It also utilizes the ftrace enabled_functions file that # keeps track of functions that have been modified in the kernel, to # allow for security auditing. # # - Allow for kernel internal use of ftrace instances. # # Subsystems in the kernel can now create and destroy their own # tracing instances which allows them to have their own tracing # buffer, and be able to record events without worrying about other # users from writing over their data. # # - New seq_buf_hex_dump() that lets users use the hex_dump() in their # seq_buf usage. # # - Notifications now added to tracing_max_latency to allow user space # to know when a new max latency is hit by one of the latency # tracers. # # - Wider spread use of generic compare operations for use of bsearch # and friends. # # - More synthetic event fields may be defined (32 up from 16) # # - Use of xarray for architectures with sparse system calls, for the # system call trace events. # # This along with small clean ups and fixes" # # * tag 'trace-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (51 commits) # tracing: Enable syscall optimization for MIPS # tracing: Use xarray for syscall trace events # tracing: Sample module to demonstrate kernel access to Ftrace instances. # tracing: Adding new functions for kernel access to Ftrace instances # tracing: Fix Kconfig indentation # ring-buffer: Fix typos in function ring_buffer_producer # ftrace: Use BIT() macro # ftrace: Return ENOTSUPP when DYNAMIC_FTRACE_WITH_DIRECT_CALLS is not configured # ftrace: Rename ftrace_graph_stub to ftrace_stub_graph # ftrace: Add a helper function to modify_ftrace_direct() to allow arch optimization # ftrace: Add helper find_direct_entry() to consolidate code # ftrace: Add another check for match in register_ftrace_direct() # ftrace: Fix accounting bug with direct->count in register_ftrace_direct() # ftrace/selftests: Fix spelling mistake "wakeing" -> "waking" # tracing: Increase SYNTH_FIELDS_MAX for synthetic_events # ftrace/samples: Add a sample module that implements modify_ftrace_direct() # ftrace: Add modify_ftrace_direct() # tracing: Add missing "inline" in stub function of latency_fsnotify() # tracing: Remove stray tab in TRACE_EVAL_MAP_FILE's help text # tracing: Use seq_buf_hex_dump() to dump buffers # ... # < /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 95f1fa9e3418d50ce099e67280b5497b9c93843b # < make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_pasemi_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- pasemi_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/linus_pasemi_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1496:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2591:6: 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:1852:6: 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:338:21: note: 'pdeo' was declared here /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/nfsd/nfs4xdr.c: In function 'nfsd4_encode_components_esc': /kisskb/src/fs/nfsd/nfs4xdr.c:2076:9: warning: 'str' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:625:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/linus_pasemi_defconfig_powerpc-gcc4.6 # Build took: 0:07:44.618673
