DragonFly 2.0 Release Notes
+HAMMER filesystem released!
+
+ - Crash recovery on-mount, no fsck.
+
- Fine-grained snapshots, snapshot management, snapshot-support
+ for filesystem-wide data integrity checks.
+
- Historically accessible by default.
+
- Mirroring: Queueless incremental mirroring, master to multi-slave.
+
- Undo and rollback.
+
- Reblocking.
+
- Multi-volume, maximum storage capacity of 1-Exabyte.
+
Kernel changes
- - Add a sysctl jail.allow_raw_sockets (default to disabled) which allows jails to use raw sockets.
+
- Add a sysctl jail.allow_raw_sockets (default to disabled) which
+ allows jails to use raw sockets.
+
- Enhance the firmware loading support.
+
- Improved random number operation.
+
- Add native fairq-queue implementation using ALTQ, for PF
+
- Add native connection state recovery to PF - so router
+ reboots do not drop active TCP connections. New 'pickups'
+ directives, and a 'set' directive to set default keep policy.
+
- Incorporate the 'probability' keyword into PDF from NetBSD.
+
- Miscellanious bug fixes to the LWP (Light Weight Process) code.
+ Fixes issues with kill -9 on vkernels.
+
- Significant work on the buffer cache and VM system relating to
+ system operation under heavy loads and with low amounts of
+ free memory.
+
- Major cleanup of the LWKT token code. This code works very well
+ now and is here to stay.
+
- Implement a cothread API and abstraction for vkernel drivers. This
+ allows a vkernel driver to use a real thread as an I/O co-processor,
+ outside of the ncpus abstraction, improving vkernel performance
+ for both UP and SMP bulids.
+
- Revamp and clean-up a good chunk of the low level pmap code in both
+ the vkernel and i386 builds. This fixes a number of access safety
+ issues and races which could occur under heavy loads.
+
- Fix issues related to gdb'ing a vkernel.
+
- Add a feature which allows boot0 and boot1 to accept commands
+ over the serial port (instead of just boot2).
+
- Fix an issue with the use of O_CREAT on read-only NFS mounts.
+
- proc structure now allocated with kmalloc instead of zalloc.
+
- Add support for local SOCK_SEQPACKET ... a connection oriented
+ protocol over unix domain sockets which retains packetization
+ boundaries for read() and write().
+
- Improve network polling support.
+
- TCP keepalives are now turned on by default.
+
- Fix ktrace support for threaded processes.
+
- kern.trap_mpsafe and kern.syscall_mpsafe are now enabled by default,
+ pushing the MP lock deeper into the kernel.
+
- Fix a memory corruption issue related to the kernel losing track
+ of the kernel's own use of the FP unit for bcopy operations.
+
- Jails can now use raw sockets if jail.allow_raw_sockets is set.
+
- CAM sync w/ FreeBSD, plus additional CAM work to fix disconnect
+ races and panics.
+
- Bring in bug fixes for UFS from FreeBSD related to when the
+ filesystem becomes full.
+
- getsockopt() and setsockopt() now copyin/copyout data early,
+ so the rest of the kernel can just access a kernel buffer.
+
- Experimental MPLS over ethernet support added.
+
- Adjust NATA queueing to not allow I/O requests to languish
+ forever due to sequential writes keeping the elevator going in
+ one direction only.
Hardware changes
- Add cmx(4) from FreeBSD, the driver for Omnikey CardMan 4040
smartcard readers.
+
- Sync NATA from FreeBSD.
+
- Sync DRM from FreeBSD.
Hardware changes (Networking)
+ - A double-ton of work on wireless drivers (by Sephe)
+
- A double-ton of work on ethernet drivers (by Sephe)
+
- Good progress made on removing the BGL from the network paths.
+ The BGL is still being left in-place for this release.
+
- Some significant Bluetooth stack work has been done.
+
- Greatly imrpoved packet routing on SMP systems.
+
- Greatly improved polling support.
+
- Greatly improved interrupt moderation support with certain
+ drivers.
Hardware changes (USB)
+ - Better survivability when pulling mass storage devices
+ without unmounting.
+
- Add many more device IDs across the board.
+
- Recognize when a device is pulled out of a firewire port (sbp).
+
- Numerous fixes made to ugen(4), including using interrupt
+ endpoints to increase responsiveness.
+
- A few fixes made to firewire (fwohic).
+
- Defer bus exploration to allow ehci to initialize. Add
+ a boot loader tunable hw.usb.hack_defer_exploration which
+ defaults to 1 and can be set to 0 to rever to the old behavior.
Userland changes
- - Citrus iconv was synced with NetBSD.
- Add blacklist feature for weak Debian-generated SSH keys.
+
- Miscellanious additions to help with pkgsrc compatibility.
+ O_SYNC, O_FSYNC.
+
- Improved ktrdump.
+
- Unique mode history feature added to /bin/sh (from NetBSD).
+
- Many improvements to manual pages and documentation.
+
- mount_nfs no longer gets confused by domain names which start
+ with a digit.
+
- Improved pkg_search
+
- Removal of remaining (x)ntpd bits. dntpd is the official NTP
+ client for DragonFly.
+
- Lots of adjustments to libthread_xu to enhance pkgsrc compatibility
+ and thread support.
+
- Installer moved to contrib / direct-compile, instead of using
+ pkgsrc.
+
- Properly clear the direction flag (DF) on entry to a signal handler.
+
- cpdup enhanced to support a verification mode, better remote
+ operation, and parallelization.
+
- Add vknet and vknetd ... a simple userland virtual ether switch,
+ making user-run vkernel execution possible.
+
- Add lsearch(3) and lfind(3) to libc.
+
- Bug fixes to strcspn() and strspn() from FreeBSD.
+
- Add a new utility 'notty', which runs a program detached from
+ the terminal.
+
- du now collects information with a 64 bit quantity instead of a
+ 32 bit quantity. ls now displays inode numbers as 64 bit integers.
+
- Add objc support to gcc.
- Build the installer as part of normal build-/installworld if WANT_INSTALLER is set.
