2012-10-25pch_gbe: fix error handling in pch_gbe_up()Veaceslav Falico
If we fail to allocate rx buffers pool by any reason, we'll just return with an error, however we've previously successfully requested an irq. Fix this by releasing the irq before returning the error. Signed-off-by: Veaceslav Falico <vfalico@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-10-24sysfs: sysfs_pathname/sysfs_add_one: Use strlcat() instead of strcat()Geert Uytterhoeven
The warning check for duplicate sysfs entries can cause a buffer overflow when printing the warning, as strcat() doesn't check buffer sizes. Use strlcat() instead. Since strlcat() doesn't return a pointer to the passed buffer, unlike strcat(), I had to convert the nested concatenation in sysfs_add_one() to an admittedly more obscure comma operator construct, to avoid emitting code for the concatenation if CONFIG_BUG is disabled.

57b30ae77b ("workqueue: reimplement cancel_delayed_work() using try_to_grab_pending()") made cancel_delayed_work() always return %true unless someone else is also trying to cancel the work item, which is broken - if the target work item is idle, the return value should be %false. try_to_grab_pending() indicates that the target work item was idle by zero return value.

2012-10-24apparmor: fix IRQ stack overflow during free_profileJohn Johansen
BugLink: http://bugs.launchpad.net/bugs/1056078 Profile replacement can cause long chains of profiles to build up when the profile being replaced is pinned. When the pinned profile is finally freed, it puts the reference to its replacement, which may in turn nest another call to free_profile on the stack. Because this may happen for each profile in the replacedby chain this can result in a recusion that causes the stack to overflow. Break this nesting by directly walking the chain of replacedby profiles (ie. use iteration instead of recursion to free the list). This results in at most 2 levels of free_profile being called, while freeing a replacedby chain.
