module: fix ddebug_remove_module()

2017-07-25T13:08:32Z

ddebug_remove_module() use mod->name to find the ddebug_table of the module and remove it. But dynamic_debug_setup() use the first _ddebug->modname to create ddebug_table for the module. It's ok when the _ddebug->modname is the same with the mod->name. But livepatch module is special, it may contain _ddebugs of other modules, the modname of which is different from the name of livepatch module. So ddebug_remove_module() can't use mod->name to find the right ddebug_table and remove it. It can cause kernel crash when we cat the file /dynamic_debug/control.

Merge tag 'trace-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

2017-07-07T02:45:45Z

Pull tracing updates from Steven Rostedt: "The new features of this release: - Added TRACE_DEFINE_SIZEOF() which allows trace events that use sizeof() it the TP_printk() to be converted to the actual size such that trace-cmd and perf can parse them correctly. - Some rework of the TRACE_DEFINE_ENUM() such that the above TRACE_DEFINE_SIZEOF() could reuse the same code. - Recording of tgid (Thread Group ID). This is similar to how task COMMs are recorded (cached at sched_switch), where it is in a table and used on output of the trace and trace_pipe files. - Have ":mod:" be cached when written into set_ftrace_filter. Then the functions of the module will be traced at module load. - Some random clean ups and small fixes" * tag 'trace-v4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (26 commits) ftrace: Test for NULL iter->tr in regex for stack_trace_filter changes ftrace: Decrement count for dyn_ftrace_total_info for init functions ftrace: Unlock hash mutex on failed allocation in process_mod_list() tracing: Add support for display of tgid in trace output tracing: Add support for recording tgid of tasks ftrace: Decrement count for dyn_ftrace_total_info file ftrace: Remove unused function ftrace_arch_read_dyn_info() sh/ftrace: Remove only user of ftrace_arch_read_dyn_info() ftrace: Have cached module filters be an active filter ftrace: Implement cached modules tracing on module load ftrace: Have the cached module list show in set_ftrace_filter ftrace: Add :mod: caching infrastructure to trace_array tracing: Show address when function names are not found ftrace: Add missing comment for FTRACE_OPS_FL_RCU tracing: Rename update the enum_map file tracing: Add TRACE_DEFINE_SIZEOF() macros tracing: define TRACE_DEFINE_SIZEOF() macro to map sizeof's to their values tracing: Rename enum_replace to eval_replace trace: rename enum_map functions trace: rename trace.c enum functions ...

kernel/module.c: use linux/set_memory.h

2017-07-06T23:24:30Z

This header always exists, so doesn't require an ifdef around its inclusion. When CONFIG_ARCH_HAS_SET_MEMORY=y it includes the asm header, otherwise it provides empty versions of the set_memory_xx() routines. The usages of set_memory_xx() are still guarded by CONFIG_STRICT_MODULE_RWX.
