Some APs broadcast WPS IE frames with totally broken data. Ifconfig's printwpsie()
loops through WPS frames printing the attributes out; if the frame's data is bad,
printwpsie() can end up looking at out-of-bounds addresses causing ifconfig to
bus error.
Thanks to Takashi Inoue at Nihon U for his efforts in debugging this.

the remaining time can be returned.
The API is similar to clock_nanosleep(3). Thanks to Ed Schouten

The blacklistd daemon keeps records of failed login attempts for
each address:port that is flagged as a failed login. When a
successful login occurs for that address:port combination,
the record's last update time is set to zero, to indicate no current
failed login attempts.
Reset the failed login count to zero, so that at the next failed
login attempt, the counting will restart properly at zero. Without
this reset to zero, the first failed login after a successful login
will cause the address to be blocked immediately.

The MIPS ABI does not require the second GOT entry to be reserved for use
by the runtime linker as on other architectures. Instead, static linkers
use a special value in the second GOT entry to indicate if the entry is
reserved. This value is supposed to consist of an address with the MSB
set and the rest of the bits all zero which is an invalid user address.
However, the old binutils currently in the tree uses the 32-bit mask value
(2^31) on 64-bit MIPS instead of 2^63. This was fixed in upstream
binutils in 2008 to use 2^63 on 64-bit MIPS.
The first part of this change changes the runtime check in init_pltgot()
to check for both values (2^31 and 2^63) when deciding whether to store
the current object pointer in GOT[1] which fixes dynamic N64 binaries
compiled with modern binutils.
However, the initial version of this fix exposed another related bug in
that _rtld_relocate_nonplt_self() was only checking for the new value
(2^63) in GOT[1] and incorrectly treated GOT[1] as a local GOT entry
(and did not relocate the final local GOT entry). To handle this, fix
all of the places that check for GOT[1]'s status to use the same macro
that checks for both values on N64.

When blocking an address, the blacklist-helper script
needs to do the following things for the ipfw packet
filter:
- create a table to hold the addresses to be blocked,
so lookups can be done quickly, and place the address
to be blocked in that table
- create rule that does the lookup in the table and
blocks the packet
The ipfw system allows multiple rules to be inserted for
a given rule number. There only needs to be one rule
to do the lookup per port. Modify the script to probe
for the existence of the rule before attempting to create
it, so only one rule is inserted, rather than one rule per
blocked address.

in a function declaration, then the compilation fails with:

The feature does work if the parameter is named.
