actually had this done at one point and lost it somewhere along the
line. Again, this is an honest to gosh bug fix only: no functionality
is changed.
- After a child broadcaster process dies or is killed, set its dom_pipe_fds
descriptors to -1 so that the 'READFD > 0' test in the select() loop
does the right thing.
Since descriptor values can be re-used, failure to do this can lead
to a situation where a descriptor for an RPC socket can be mistaken for
a pipe. If this happens, RPC sockets could be incorrectly handed off to
handle_children(), which would then clear the descriptor from the select()
descriptor mask and prevent svc_getreqset() from handling them. The end
result would be that some RPC events would go unserviced. Curiously,
the failures only happen intermittently.
BTW, if somebody would like to take a look at the German
README I notice that the special characters got totally stripped
somehow and I'm not entirely sure how to put them back! [-jkh] :(

Folks - please review these! I'm quite sleepy at the moment, and I'm
sure that some of this could be worded better. I'd like to have at least
a reasonable syntax pass over this before handing it off to the translation
folks! Thanks! Feel free to commit any changes directly if it's any time
in the next 8 hours, BTW. I won't mind since I'll be asleep!
- the major number wasn't checked, so accesses beyond the end of bdevsw[]
were possible. Bogus major numbers are easy to get because `sysctl -w'
doesn't handle dev_t's reasonably - it doesn't convert names to dev_t's
and it converts the number 1025 to the dev_t 0x35323031.
- Driver d_psize() functions return -1 to indicate error ENXIO or ENODEV
(the interface is too braindamaged to say which). -1 was interpreted
as a size and resulted in the bogus error ENOSPC.
- it was possible to set the dumpdev for devices without a d_psize()
function. This is equivalent to setting the dumpdev to NODEV except
it confuses sysctl.
- change a 512 to DEV_BSIZE. There is an official macro dtoc() for
converting "pages" to disk blocks but it is never used in /usr/src/sys.
There is much confusion between PAGE_SIZE sized pages and NBPG sized
pages. Maxmem consists of both.
Not fixed:
- there is nothing to invalidate the dumpdev if the media goes away.
This reduces the benefits of the early calculation of dumplo. Bounds
checking in the dump routines is relied on to reduce the risk of
damage and little would be lost by relying on the dump routines to
calculate dumplo.
- no attempt is made to stay away from the start of the device to
avoid clobbering labels.
Fix wrong && anachronistic comment about the type of bootdev.

handled correctly. This would manifest itself as "object deallocated too
many times" panics and perhaps other strange inconsistencies on NFS servers.

Remove unused devices (*[sw]d*[bdefgh]).
Dont gzip boot_crunch. (This SAVES space on a 4 MB machine, since the
file can be segment can be paged from now.
This (with the kzip patch) makes a 4M machine boot and run again.
Margin in my build is 22 blocks and 9 inodes.
I will look at tgz'ing the help files, we need that.
Add a NOMAN= . It doesn't have a manual page yet.
Please don't cry :-). I ask Rod first. the whole isdn subdir is not
used in the moment and is only dead source code in the tree.
Add Bt956 as being supported.
Include 2940 in the 2742/2842 section.
Anyone with a new feature or driver in 2.0.5 should think about adding "blurbs"
to this file. Some features say exactly what they do, others say nothing...
this document needs some rounding out.
LINT talks about about 2.1. I changed that to 2.0.5,
and clarified why certain devices need "at scbus?".
There is still a crazy "PCVT=210" which shouldn't be there,
but corrected comment as it is needed for 2.0.5.
