in IP headers, so we have to deduct not only IP option headers but all
IP headers. But in TCP/UDP layer we can assume the IP header is valid
and a sum of the IP header part should be 0xffff, so we don't have to
bother to deduct it from the computed checksum.
UNIX domain socket, based on an example program by Michael van Elst.
This fixes support for using milters (Sendmail Mail Filters) with
Postfix under at least NetBSD/amd64.
which apparently don't exist as instructions, with a sequence of
std / ld instructions.
Also remove the attempted include of ldstm.S which we don't have.
ddb running on crash dumps, but with two notable changes:
- Breakpoints, watches, etc are obviously never going to work so they
are not handled.
- You can pipe output to the shell, e.g. ps | grep foo
Items remaining to be done:
- Port it to architectures other than i386. This isn't difficult, just
a case of making db_disasm.c/db_trace.c or their equivalent compile
and work.
- Make more of the "show" commands work, e.g "show uvmexp".
types of changes:
- Add a few new methods to replace stuff like p_find(), CPU_INFO_FOREACH.
- Use db_read_bytes() instead of accessing kernel structures directly,
and similar changes.
- Add ifdef _KERNEL where the above hasn't been done, and an XXX comment.
target after the recent addition of BFD_DETERMINISTIC_OUTPUT to libbfd.
The list of architectures is not complete, but these were the
ones I had readily-available toolchains for. The rest will be
dealt with a little later, by me or someone else.
which don't have EXT_RFA and IPCB support. From hme(4) driver and
FreeBSD's fxp(4). Tested on i82559.
XXX: Probably we should have a common function to parse RX packet headers
XXX: to handle a raw checksum value and share it among hme(4) and gem(4) etc.
already powered down. This change prevents PCI bus exceptions
(indicated by NMI) when, for example, I detach the whole device
tree on a Soekris net4521:
com1: detached
NMI ... going to debugger
Stopped in pid 0.1 (system) at netbsd:sipcom_stop+0x4d: pushl $0
db{0}> continue
NMI ... going to debugger
Stopped in pid 0.1 (system) at netbsd:sipcom_stop+0x149: addl $0x10,%e
sp
db{0}> continue
sip0: detached
(On the AMD Elan SC520, the NMI occurs at the instruction after
the write or, if the write was posted, at either that instruction
or some later one.)
