to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

The commit includes:
- Flash layer, which gives a common API to access flash devices
- NAND controller subsystem for the flash layer
- An example OMAP driver which is used on BeagleBoard or alike ARM boards
"FSS_UNLINK_ON_CREATE" to unlink the backing store before
the snapshot gets created.
With this change dump(8) no longer dumps the zero-sized, but named
snapshot it is working on. Same applies to fsck_ffs(8).
2 and a bit ethernet packets. Check and increase SO_RCVBUF on startup
so that we have buffers for 10 complete packets, should solve a
reported problem with overruns at higher connection speeds (our L2CAP
does not have any flow control).
(the default can still be adjusted upwards using sysctl)
copyright. Confirmed by Mike Hibler, mike at cs.utah.edu - thanks!
Also, merge UCB and Utah copyright texts back into one, as they
originally were.
Extra verification by snj@.
- Add libnpf(3) - a library to control NPF (configuration, ruleset, etc).
- Add NPF support for ftp-proxy(8).
- Add rc.d script for NPF.
- Convert npfctl(8) to use libnpf(3) and thus make it less depressive.
Note: next clean-up step should be a parser, once dholland@ will finish it.
- Add more documentation.
- Various fixes.
NetBSD/emips port runs on Xilinx and Beecube FPGA systems and the
Giano system simulator.
eMIPS is a platform developed at Microsoft Research for researching
reconfigurable computing. eMIPS allows dynamic loading and scheduling
of application-specific circuits for the purpose of accelerating
computations based on the current workload.
NetBSD eMIPS support for NetBSD 4.x was written at Microsoft Research
by Alessandro Forin and Neil Pittman. Microsoft Corporation has
donated full copyright to The NetBSD Foundation.
Platform support for eMIPS is the first part of Microsoft's
contribution. The second part includes the hardware accelerator
framework and will be proposed on tech-kern soon.
- Add the concept of rule procedure: separate normalization, logging and
potentially other functions from the rule structure. Rule procedure can be
shared amongst the rules. Separation is both at kernel level (npf_rproc_t)
and configuration ("procedure" + "apply").
- Fix portmap sharing for NAT policy.
- Update TCP state tracking logic. Use TCP FSM definitions.
- Add if_byindex(), OK by matt@. Use in logging for the lookup.
- Fix traceroute ALG and many other bugs; misc clean-up.
use neighbour specific options - XXX: needs documentation
* add peer authentication using TCP_MD5SIG. Interoperability tested with
Cisco IOS
* use SLIST_FOREACH_SAFE when deleting labels instead of re-looping.
- Add support for session saving/restoring.
- Add packet logging support (can tcpdump a pseudo-interface).
- Support reload without flushing of sessions; rework some locking.
- Revisit session mangement, replace linking with npf_sentry_t entries.
- Add some counters for statistics, using percpu(9).
- Add IP_DF flag cleansing.
- Fix various bugs; misc clean-up.
skip past the display columns that the value would otherwise occupy.
Fixes display issue when swsensor(4) is used and it has a value of 0K,
as reported by njoly@
new upstream version of traceroute to import.
AS# lookup is still done using host networking. Rationale: the
relevance to where that data comes from with respect to network
tracing is zero (be it socket, local file, db, whatever).
- Add proper TCP state tracking as described in Guido van Rooij paper,
plus handle TCP Window Scaling option.
- Completely rework npf_cache_t, reduce granularity, simplify code.
- Add npf_addr_t as an abstraction, amend session handling code, as well
as NAT code et al, to use it. Now design is prepared for IPv6 support.
- Handle IPv4 fragments i.e. perform packet reassembly.
- Add support for IPv4 ID randomization and minimum TTL enforcement.
- Add support for TCP MSS "clamping".
- Random bits for IPv6. Various fixes and clean-up.
This works around read(2) system callsfailing with ENOBUFS.
This is a hack bedause there is no way to know that 4 * FUSE_BUFSIZE
will be enough to hold queued FUSE frames. It seems good enough at
mine.
- use PUFFS_KFLAG_WTCACHE to puffs_init so that all writes are
immediatly send to the filesystem, and we do not have anymore write
after inactive. As a consequence, we can close files at inactive
stage, and there is not any concern left with files opened at
create time. We also do not have anymore to open ourselves in readdir and
fsync.
- Fsync on close (inactive stage). That makes sure we will not need to
do these operations once the file is closed (FUSE want an open file).
short sircuit the request that come after the close, bu not fsinc'ing
closed files,
- Use PUFFS_KFLAG_IAONDEMAND to get less inactive calls
== Removed nodes ==
- more ENOENT retunred for operations on removed node (but there
are probably some still missing): getattr, ooen, setattr, fsync
- set PND_REMOVE before sending the UNLINK/RMDIR operations so that we avoid
races during UNLINK completion. Also set PND_REMOVED on node we overwirte
in rename
== Filehandle fixes ==
- queue open operation to avoid getting two fh for one file
- set FH in getattr, if the file is open
- Just requires a read FH for fsyncdir, as we always opendir in read
mode. Ok, this is misleading :-)
== Misc ==
- do not set FUSE_FATTR_ATIME_NOW in setattr, as we provide the time
- short circuit nilpotent operations in setattr
- add a filename diagnostic flag to dump file names
