(force) is given. fsck(8) will return with a zero exit status if "fsck -p"
is used in this circumstance, but all other invocations (e.g, "fsck",
"fsck /filesystem", "fsck -p /filesystem") will return with a non-zero exit
status in this circumstance.
Per discussions with various people including Bill Sommerfeld.
- Use "file system" instead of "filesystem"
a little used server daemon which can be controlled with rc.conf in any case.
(xxx: list of files probably should be totally configurable, but that's
another story). from [bin/13061] by matthew green.
for FreeBSD project. Besides huge speed boost compared with socketpair-based
pipes, this implementation also uses pagable kernel memory instead of mbufs.
Significant differences to FreeBSD version:
* uses uvm_loan() facility for direct write
* async/SIGIO handling correct also for sync writer, async reader
* limits settable via sysctl, amountpipekva and nbigpipes available via sysctl
* pipes are unidirectional - this is enforced on file descriptor level
for now only, the code would be updated to take advantage of it
eventually
* uses lockmgr(9)-based locks instead of home brew variant
* scatter-gather write is handled correctly for direct write case, data
is transferred by PIPE_DIRECT_CHUNK bytes maximum, to avoid running out of kva
All FreeBSD/NetBSD specific code is within appropriate #ifdef, in preparation
to feed changes back to FreeBSD tree.
This pipe implementation is optional for now, add 'options NEW_PIPE'
to your kernel config to use it.
network interfaces. This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us. In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software. This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.
We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.
Note: hardware-assisted checksumming defaults to "off". It is
enabled with ifconfig(8). See the manual page for details.
Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.
- if it's a path to an unmounted file-system listed in /etc/fstab, use
that instead of assuming the user wanted a subtree dump of the parent
directory. this restores the behaviour of dump before the subtree
dumping code went in.
- if it's a path to a mounted file-system which is not in /etc/fstab,
use the info from getmntinfo(3). previously, dump would choke.
* implement error checked malloc(), calloc(), strdup(), and use
appropriately (some of the calloc()s weren't being checked)
* use 'file-system' instead of 'filesystem' in the man page
- add a function to print only one partition's info.
- print the partition information if it was modified in interactive mode.
- improve on the chaining code. [still assumes that partition offsets increase
monotonically]. We could check for overlap too.
the offset of an extended sub-partition is the offset of the top-level
extended partition, not the partition before it (this is annoying, and
makes `clean' recursive mbr descent difficult). fixes PRs 11829 and 12677.
otherwise an unaligned address gets passed to the linker. (which is
rounded there, so this is harmless)
XXX how about passing "-N" and killing all these hacks?
The most significant [fix] involves so called "remote" interfaces
configured in the kludge file to with what appear to be colliding
networks. Edward Mascarenhas <eddiem@vihar.engr.sgi.com> found
the problem and the fix, and I think has tested it in the SGI
network.
each of the basic types (anonymous data, executable image, cached files)
and prevent the pagedaemon from reusing a given page if that would reduce
the count of that type of page below a sysctl-setable minimum threshold.
the thresholds are controlled via three new sysctl tunables:
vm.anonmin, vm.vnodemin, and vm.vtextmin. these tunables are the
percentages of pageable memory reserved for each usage, and we do not allow
the sum of the minimums to be more than 95% so that there's always some
memory that can be reused.
- clean up WARNS=2 problems
- implement getshort()
- use getshort() with MBR_MAGICOFF to test if the magic number is OK, rather
than using hard-coded magic numbers
normal operation (/var can get filled up by flodding bogus packets).
sysctl net.inet6.icmp6.nd6_debug will turn on diagnostic messages.
(#define ND6_DEBUG will turn it on by default)
improve stats in ND6 code.
lots of synchronziation with kame (including comments and cometic ones).
let static routes overwrite cloned routes, as cloned routes can come back again
if necessary. behavior same as freebsd/bsdi, code partially from bsdi42.
(NRL rt->rt_parent was not added)
should fix PR 11916 and maybe some other PRs with ARP behavior.
recompilation of usr.sbin/route6d is suggested.
XXX route show is total duplicate of netstat -r, we need to either remove
route show, or share the same source code, otherwise maintenance cost

the current in-core master superblock, and fix them up if
they're incorrect. Move the code that writes the alternate
superblocks if (cvtlevel || doswap) into pass 5 for efficiency.
Reviewd by Charles Hannum, and used by me to fix up a curdled
file system.
'int compress' in savecore.c and the function 'compress' in libz.
Gnu ld 2.10 (with BFD 2.10) used on sparc64 warns this conflict
(symbol "compress" changed size).
