* Several years ago a feature was added to TCP that casued soreceive() toJohn Baldwin2009-11-061-1/+1
| | | | | | | | | | | | | | | | send an ACK right away if data was drained from a TCP socket that had previously advertised a zero-sized window. The current code requires the receive window to be exactly zero for this to kick in. If window scaling is enabled and the window is smaller than the scale, then the effective window that is advertised is zero. However, in that case the zero-sized window handling is not enabled because the window is not exactly zero. The fix changes the code to check the raw window value against zero.

| | | | | | | | | | | | | | bge_newbuf_std still has a bug for handling dma map load failure under high network load. Just reusing mbuf is not enough as driver already unloaded the dma map of the mbuf. Graceful recovery needs more work. Ideally we can just update dma address part of a Rx descriptor because the controller never overwrite the Rx descriptor. This requires some Rx initialization code changes and it would be done later after fixing other incorrect bus_dma(9) usages. Notes: svn path=/head/; revision=198924

* Make /dev/klog and kern.msgbuf* MPSAFE.Ed Schouten2009-11-033-37/+58
| | | | | | | | | | | | | | | | | Normally msgbufp is locked using Giant. Switch it to use the msgbuf_lock. Instead of changing the tsleep() calls to msleep(), just convert it to condvar(9). In my opinion the locking around msgbuf_peekbytes() still remains questionable. It looks like locks are dropped while performing copies of multiple blocks to userspace, which may cause the msgbuf to be reset in the mean time. At least getting it underneath from Giant should make it a little easier for us to figure out how to solve that. Reminded by: rdivacky Notes: svn path=/head/; revision=198860
* Fix VESA color palette corruption:Jung-uk Kim2009-11-033-59/+40
| | | | | | | | | | | | | | | - VBE 3.0 says palette format resets to 6-bit mode when video mode changes. We simply set 8-bit mode when we switch modes if the adapter supports it. - VBE 3.0 also says if the mode is not VGA compatible, we must use VBE function to save/restore palette. Otherwise, VGA function may be used. Thus, reinstate the save/load palette functions only for non-VGA compatible modes regardless of its palette format. - Let vesa(4) set VESA modes even if vga(4) claims to support it. - Reset default palette if VESA pixel mode is set initially. - Fix more style nits.
