Fix race between cat /proc/slab_allocators and rmmod

2007-05-08T18:15:08+00:00

Same story as with cat /proc/*/wchan race vs rmmod race, only
/proc/slab_allocators want more info than just symbol name.

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

2007-05-08T18:15:08+00:00

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()

2007-05-08T18:15:08+00:00

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.

Fix race between rmmod and cat /proc/kallsyms

2007-05-08T18:15:08+00:00

module_get_kallsym() leaks "struct module *" outside of module_mutex which is
no-no, because module can dissapear right after mutex unlock.

Copy all needed information from inside module_mutex into caller-supplied
space.

Simplify module_get_kallsym() by dropping length arg

2007-05-08T18:15:08+00:00

module_get_kallsym() could in theory truncate module symbol name to fit in
buffer, but nobody does this.  Always use KSYM_NAME_LEN + 1 bytes for name.

Suggested by lg^WRusty.

module: use krealloc

remove "struct subsystem" as it is no longer needed

2007-05-03T01:57:59+00:00

We need to work on cleaning up the relationship between kobjects, ksets and
ktypes.  The removal of 'struct subsystem' is the first step of this,
especially as it is not really needed at all.

Thanks to Kay for fixing the bugs in this patch.

[PATCH] x86: Allow percpu variables to be page-aligned

2007-05-02T17:27:12+00:00

Let's allow page-alignment in general for per-cpu data (wanted by Xen, and
Ingo suggested KVM as well).

Because larger alignments can use more room, we increase the max per-cpu
memory to 64k rather than 32k: it's getting a little tight.
