9 years agoWhen catopen(3) returns an error, it caches the result of that error

When catopen(3) returns an error, it caches the result of that error
from r202992. The refcount on the cache entry is not initialized, so

This fixes a bug in the way that the LLE timers for nd6
and arp were being used. They basically would pass in the
mutex to the callout_init. Because they used this method
to the callout system, it was possible to "stop" the callout.
When flushing the table and you stopped the running callout, the
callout_stop code would return 1 indicating that it was going
to stop the callout (that was about to run on the callout_wheel blocked
by the function calling the stop). Now when 1 was returned, it would
lower the reference count one extra time for the stopped timer, then
a few lines later delete the memory. Of course the callout_wheel was
stuck in the lock code and would then crash since it was accessing
freed memory. By using callout_init(c, 1) we always get a 0 back
and the reference counting bug does not rear its head. We do have
to make a few adjustments to the callouts themselves though to make
sure it does the proper thing if rescheduled as well as gets the lock.

  [FastIsel][X86] Fix invalid register replacement for bool args

  Summary:
  Consider the following IR:

   %3 = load i8* undef
   %4 = trunc i8 %3 to i1
   %5 = call %jl_value_t.0* @foo(..., i1 %4, ...)
   ret %jl_value_t.0* %5

  Bools (that are the result of direct truncs) are lowered as whatever
  the argument to the trunc was and a "and 1", causing the part of the
  MBB responsible for this argument to look something like this:

   %vreg8<def,tied1> = AND8ri %vreg7<kill,tied0>, 1, %EFLAGS<imp-def>; GR8:%vreg8,%vreg7

  Later, when the load is lowered, it will insert

   %vreg15<def> = MOV8rm %vreg14, 1, %noreg, 0, %noreg; mem:LD1[undef] GR8:%vreg15 GR64:%vreg14

  but remember to (at the end of isel) replace vreg7 by vreg15. Now for
  the bug. In fast isel lowering, we mistakenly mark vreg8 as the result
  of the load instead of the trunc. This adds a fixup to have
  vreg8 replaced by whatever the result of the load is as well, so
  we end up with

   %vreg15<def,tied1> = AND8ri %vreg15<kill,tied0>, 1, %EFLAGS<imp-def>; GR8:%vreg15

  which is an SSA violation and causes problems later down the road.
