kernel: use non-racy method for proc entries creation

2008-04-29T15:06:22Z

Use proc_create()/proc_create_data() to make sure that ->proc_fops and ->data be setup before gluing PDE to main tree. Signed-off-by: Denis V. Lunev Cc: Alexey Dobriyan Cc: "Eric W. Biederman" Cc: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

timer_list: print relative expiry time signed

2008-02-17T16:29:38Z

Relative expiry time can get negative, so it should be signed. Signed-off-by: Pavel Machek Signed-off-by: Thomas Gleixner

tick-sched: add more debug information

2008-02-01T16:45:14Z

To allow better diagnosis of tick-sched related, especially NOHZ related problems, we need to know when the last wakeup via an irq happened and when the CPU left the idle state. Add two fields (idle_waketime, idle_exittime) to the tick_sched structure and add them to the timer_list output. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

timer_list: Fix printk format strings

2007-10-29T08:39:38Z

This makes sure printk format strings contain no more than a single line. Signed-off-by: Vegard Nossum Signed-off-by: Thomas Gleixner

Fix leaks on /proc/{*/sched,sched_debug,timer_list,timer_stats}

2007-07-31T22:39:40Z

On every open/close one struct seq_operations leaks. Kudos to /proc/slab_allocators. Signed-off-by: Alexey Dobriyan Acked-by: Ingo Molnar Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kallsyms: make KSYM_NAME_LEN include space for trailing '\0'

2007-07-17T17:23:03Z

KSYM_NAME_LEN is peculiar in that it does not include the space for the trailing '\0', forcing all users to use KSYM_NAME_LEN + 1 when allocating buffer. This is nonsense and error-prone. Moreover, when the caller forgets that it's very likely to subtly bite back by corrupting the stack because the last position of the buffer is always cleared to zero. This patch increments KSYM_NAME_LEN by one and updates code accordingly. * off-by-one bug in asm-powerpc/kprobes.h::kprobe_lookup_name() macro is fixed. * Where MODULE_NAME_LEN and KSYM_NAME_LEN were used together, MODULE_NAME_LEN was treated as if it didn't include space for the trailing '\0'. Fix it. Signed-off-by: Tejun Heo Acked-by: Paulo Marques Cc: Benjamin Herrenschmidt Cc: Paul Mackerras Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Fix printk format warnings in timer_list.c

2007-05-09T19:30:50Z

u64 and s64 are not necessarily 'long long' on some 64-bit platforms, so explicit the type to kill the compiler warnings. Also consistently use '%Lu' which is unsigned. Signed-off-by: David S. Miller Cc: Thomas Gleixner Cc: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Fix race between cat /proc/*/wchan and rmmod et al

2007-05-08T18:15:08Z

kallsyms_lookup() can go iterating over modules list unprotected which is OK for emergency situations (oops), but not OK for regular stuff like /proc/*/wchan. Introduce lookup_symbol_name()/lookup_module_symbol_name() which copy symbol name into caller-supplied buffer or return -ERANGE. All copying is done with module_mutex held, so...

Simplify kallsyms_lookup()

2007-05-08T18:15:08Z

Several kallsyms_lookup() pass dummy arguments but only need, say, module's name. Make kallsyms_lookup() accept NULLs where possible. Also, makes picture clearer about what interfaces are needed for all symbol resolving business.

[PATCH] time: fix formatting in /proc/timer_list

2007-03-23T18:01:21Z

Fix the print formatting of three unsigned long fields in /proc/timer_list, which are currently being formatted as signed long. Signed-off-by: James Morris Acked-by: Ingo Molnar Cc: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
