get its ACKs faster.
From Darwin via FreeBSD.
XXX I don't have any idea if this is useful or reasonable, but it looks
XXX sane and the code works. "Remove if found nonuseful."
This makes it possible to use files >4G.
From Darwin via FreeBSD, but changed so that smb_{read|write}() directly
calls appropriate i/o variant, and replaced md_get_uint16le() with
md_get_uint16() for target == NULL cases.
Replace some size_t's by int's.
use temporary variable to fetch the 16bit value instead
remove some redundant temporaries, use NULL for those md_get_*() calls instead
make sv_sm 16bit - it is 16bit in later SMB dialects
iod_sleeptimo is set to same value always, so use the value directly
and #if 0 iod_sleeptimo
add one smb_iod_wakeup() in smb_iod_sendrq()
XXX unfortunately iod thread still must wakeup periodically to check
XXX for arriving replies - command latency might be improved if this could
XXX be avoided
* no need to use dummy variables for md_get_*(), just use NULL
* don't bother storing rpflags/rpflags2, it's not used anywhere
* g/c local variable rperror
sent out, use mono_time instead microtime(), and simplify computation
in smb_iod_sendall(). Also count the timout once, not twice as previous code.
#if 0 iod->iod_lastrqsent, it was write-only
that our lint does not understand.
One of these extensions (local labels) is needed only when using multiple
try/catch blocks within a function, and the comment before these macros
say that they should be used only once per function so that the implementaton
may be portable.
The other extension (taking the address of a label) is not needed at all.
Remove the use of the extensions.
Do a little mbuf rework while here. Change all uses of MGET*(*, M_WAIT, *)
to m_get*(M_WAIT, *). These are not performance critical and making them
call m_get saves considerable space. Add m_clget analogue of MCLGET and
make corresponding change for M_WAIT uses.
Modify netinet, gem, fxp, tulip, nfs to support MBUFTRACE.
Begin to change netstat to use sysctl.
intent); besides being reable now, this fixes (several!) bugs in
timeout calculation, which caused nbssn_rselect() to return
prematurely
put the timeout in separate variable declared on top, so that it's clear
where the value comes from
don't adjust timeout in smb_nbst_connect() - this made the timeout
too short if connect happened to be fast
(XXX perhaps reevaluate this later and put back in some other form)
bump NB_SNDQ/NB_RCVQ to 64k, and actually use the defines to set
snd/rcv buffer sizes
use #define for the snd/rcv timeo
some whitespace/KNF fixes
p_sigmask or p_sigignore, so no point explicitly removing them
also kill some compatibility macros/defines and use the real thing directly,
it's more readable that way
