unexpectedly do not complete writes even with sync I/O requests.
This should help the behavior of mmaped files when using
softupdates (and perhaps in other circumstances also.)
This driver supports the following cards/integrated ethernet controllers:
Compaq Netelligent 10, Compaq Netelligent 10/100, Compaq Netelligent 10/100,
Compaq Netelligent 10/100 Proliant, Compaq Netelligent 10/100 Dual Port,
Compaq NetFlex-3/P Integrated, Compaq NetFlex-3/P Integrated,
Compaq NetFlex 3/P w/ BNC, Compaq Deskpro 4000 5233MMX.
It should also support Texas Instruments NICs that use the ThunderLAN
chip, though I don't have any to test. If you've got a card that uses
the ThunderLAN chip but isn't listed in the PCI vendor/product list in
if_tl.c, try adding it and see what happens.
The driver supports any MII compliant PHY at 10 or 100Mbps speeds in
full or half duplex. (Those I've personally tested are the National
Semiconductor DP83840A (Prosignia server), the Level 1 LXT970 (Deskpro
desktop), and the ThunderLAN's internal 10baseT PHY.) Autonegotiation,
hardware multicast filtering, BPF and ifmedia support are included.
This chip is pretty fast; Prosignia servers with NCR SCSI, ThunderLAN
ethernet and FreeBSD make for a nice combination.
size we receive here should fit into the receive buffer. Unfortunately,
there's no 100% foolproof way to distinguish a ridiculously large record
size that a client actually meant to send us from a ridiculously large
record size that was sent as a spoof attempt.
The one value that we can positively identify as bogus is zero. A
zero-sized record makes absolutely no sense, and sending an endless
supply of zeroes will cause the server to loop forever trying to
fill its receive buffer.
Note that the changes made to readtcp() make it okay to revert this
sanity test since the deadlock case where a client can keep the server
occupied forever in the readtcp() select() loop can't happen anymore.
This solution is not ideal, but is relatively easy to implement. The
ideal solution would be to re-arrange the way dispatching is handled
so that the select() loop in readtcp() can be eliminated, but this is
difficult to implement. I do plan to implement the complete solution
eventually but in the meantime I don't want to leave the RPC library
totally vulnerable.
That you very much Sun, may I have another.
cases we ignore it (eg: read/write) to maintain chmod-after-open semantics
but in other cases we do care, eg: creating files, access() etc. Never
ignore errors from VOP_ACCESS() on immutable files.
This apparently comes from BSDI (from Keith Bostic) via NetBSD.

the right solution or not, bsd.port.mk is broken unless bsd.locale.mk
is installed.
Note that if LOCALE is not defined, port-building explodes:
"/usr/share/mk/bsd.locale.mk", line 135: if-less elif
"/usr/share/mk/bsd.locale.mk", line 135: Need an operator
(For each .if testing LOCALE)
almost certainly have to change as the FreeBSD/Alpha kernel comes
along, but for the transitionary period this is the most correct.

end up being the same, but it doesn't look like you're comparing
apples and oranges.
2. Use need_resched instead of reset_priority. This isn't right
either, since for example you'll round-robin against equal priority FIFO
processes when lowering the priority of another process,
but this works better and a real fix needs to be in kern_synch and
not out here.
3. This is not a device driver: copyin/copyout the structure.
