joerg 81895b4b5d 0:0 is the adress x86emu_call pushes on the stack, so check for it here
explicitly to stop processing again. As this is the start of the IDT,
normal code is not likely to override it.

joerg 89b1aba64b Fix three bugs in the instruction decoder:
(1) Mode 5 for SIB uses EBP as base, not ESP.
(2) RM register mode 5 needs a segment override for SS when not using an
    immediate in 32bit mode.
(3) Same for mode 6 in 16bit mode.

From anon ymous.

skrll 5dbd6a69ca Make sure _atomic_cas_fn is initialised for "weirdo environments" such
as ramdisks where the constructor doesn't get called.

Fixes ifconfig in hp700 sysinst.

cyber 23dc01f7e9 Properly handle empty data nodes (such as generated by Apple's
plist editor). They are in the form of <data></data>, whereas the
original code path only checked for empty being <data/>.

This causes an assert to be triggered when trying to access the node's
content.

pooka d21961207f Include sys/param.h in the kernel to make the vax properly pick up
memset.  Otherwise vax/macros.h doesn't get included and the usual
lossage ensues.
(I bet you saw that one coming)

pooka 132ffc213b Include userland version of atomic cas routines in librump.
(the kernel version disables interrupts and therefore can't be used)

pooka 1ce853369b Temporarily define MCOUNT as a dummy for _RUMPKERNEL to allow build
to proceed - the MD macros use processor instructions unavailable
to userspace and should/could be provided as interfaces.

pooka 69885c98a3 Do not use lockpatches with _RUMPKERNEL (non-PIC ... and pointless). 2009-01-04 18:46:16 +00:00
pooka 58302d6770 Opt for libc versions in case of _KERNEL && !_RUMPKERNEL.
(kernel version uses sti/cli and is not PIC)

This makes proplib simplelock-free.

ad 30fd42e845 PR kern/40213 my i386 machine can't boot because of tsc
- Patch in atomic_cas_64() twice. The first patch is early and makes it
  the MP-atomic version available if we have cmpxchg8b. The second patch
  strips the lock prefix if ncpu==1.

- Fix the i486 atomic_cas_64() to not unconditionally enable interrupts.

christos 2d2593ab23 We don't need this for _STANDALONE, and it needs snprintf to work. 2008-12-17 16:02:27 +00:00
christos cec60a5890 share with kernel; replaces bitmask_snprintf which was very broken:
- subtracted one from len without checking if len was 0
- checked for a minimum buffer size
- arguments order was inconsistent with other printf like functions
- no way to tell if it overflowed

haad e51aea320a Fix two race conditions in proplib library. In prop_dictionary and prop_number
there was small window in which was entry left in rb tree with reference
count 0 which lead to rb tree coruption when another thread picked this up
before it was released.
Add 2 new members to the prop_object_t which are used for locking/unlocking
rb tree guard mutex.

Patch from joerg@
2008-08-20 19:58:33 +00:00
joerg 245e086321 Unify the implementation of strto{l,ul,ll,ull,imax,umax,q,uq} into one
version for signed and one version for unsigned data types.

Add a check for supported bases and set errno (userland) or panic
(kernel, libsa) otherwise.

Make strto{ll,ull,imax,umax} normal symbols and just keep the underscore
versions as strong alias.

Obtained from DragonFly, based on the wide char version from Citrus.

christos ecd6bc7086 typo in comment and white-space fixes mostly from Stathis Kamperis 2008-08-11 05:54:21 +00:00
thorpej 4ce0dc3a15 Fix an issue introduced with the prop_stack change: It's not a good idea to
return a 3-value enum from a function declared to return bool.  This broke
the recurse case for prop_object_equals().  Instead, declare the object type
equals routine to return a _prop_object_equals_rv_t.

Give the same treatment to the object type free routines: declare them to
return a _prop_object_free_rv_t, and consistently check those return values
againt the enum type.

Tidy up some whitespace while we're here.
