May not set orphan symbol values to anything meaningful, but must be
allowed to unset an orphan value (which is already unset) so that
when reaming a symbol table ordinary value delete/unset functions can
be called.
So fixed the assert which was disallowing all value changes for
orphans, in symbol_set_value().

Make one version of check prefix bit, and put it inline
with proper prototype. This gets rid of some macro's and also some
assert() that can never happen on a non-broken compiler.

It seems that there is a bug in ospf6d in ospf6_lsa_compare(): If LSA A
has sequence number smaller than 0x80000000 and LSA B has sequence
number larger than 0x80000000, ospf6_lsa_compare() returns that B is
more recent than A, although RFC says that sequence numbers should be
compared as signed numbers (0x8000001 smallest and 0x7FFFFFFF largest).
In ospfd, the function ospf_lsa_more_recent() has it right.
The problem appears when Quagga is used together with OSPFv3 in
development version of BIRD daemon ( http://bird.network.cz/ ),
which creates LSAs with maximum sequence number (0x7FFFFFFF)
as a part of flushing/premature aging LSA from OSPF area.
Because both daemons has different idea of which LSA instance
is more recent, it would lead to LSA storm.

The RTF_CLONING flag has been removed in FreeBSD 8.0 with arp-v2 (see
http://svn.freebsd.org/viewvc/base/stable/8/UPDATING?view=markup),
since it no longer has any meaning. This patch checks if RTF_CLONING
exists before using it.

Avoid a potential conflict with the C99 defines 'true' and 'false'
found in <stdbool.h> by choosing better variable names.
Also fix the calls to these ioctls, as described in <net/bpf.h>
in FreeBSD, NetBSD, and OpenBSD:
* BIOCGBLEN, BIOCIMMEDIATE, BIOCSSEESENT (the parameter should be
of type 'u_int')
* BIOCPROMISC (there should be no parameters)

This code is only used one place and can be made local.
Gcc is smart enough to inline local functions if it wants to.
The function also has a big chunk of compatiablity code that
is no longer used; since quagga is now in a version control system
the source does not need to be used as a historical reference.

* kernel_socket.c: (rtm_flag_dump) Use a const message pointer to be

* ospf6_lsdb.c: (ospf6_new_ls_id) Unlock the current LSA when breaking
out of the ospf6_lsdb_*_head() / ospf6_lsdb_*_next() loop early. No
explicit unlocking is needed when all LSAs are looped through
because ospf6_lsdb_*_next() manages everything in that case.

Introduced separate types for qtime_mono_t and qtime_real_t, to
distinguish the time base of a given value.
Revised all users of timeouts so that they are all expressed as
qtime_mono_t values, so are all Quagga monotonic time based.
Revised qpt_cond_timedwait() so that all condition variables use the
same timebase (CLOCK_MONOTONIC if available, by default). Now all
timeout times are qtime_mono_t, and are converted to whatever the
condition variable is set to, if necessary.
Added explicit timeout to mqueue.
Fixed qps_pselect() to zeroise result vectors if no fds are
reported pending -- seems the O/S does not do this.

mnum, not mbits.

range of little-/big-endian word sizes and forwards/backwards bit
numbering.

Improved the arithmetic and changed code to deal with wrap around
only if clock_t is 32-bits (and not to compile if it is less !).

This allows mutexes to be initialised as recursive.
Required correctly placed setting of _GNU_SOURCE (for gcc).
It is assumed that "config.h" will enable the required pthreads
features -- which are now documented in lib/qpthread.c.

lib/qpselect supports data structure to multiplex between many file
descriptors using pselect().
lib/qtimers supports data structures to run multiple timers.
Also affected:
lib/Makefile.am -- to add the new files
lib/memtypes.c -- to add further memory types for the above
|

| | |
| | |
| | |
| | |
| | |

Added conversion routines for CLOCK_REALTIME/timeofday to/from
monotonic clock -- so can set timers to actual time, if required.
Added confirms and tidied up documentation.

Added qpt_thread_self().
Initialised output sigset_t before setting it in qpt_thread_sigmask().
