Show stopper defects for 6.0-RELEASE

Issue Status Responsible Description
"snaplk" livelock &status.wip;   Found by stress tests at http://www.holm.cc/stress/log/cons143.html.
panic: handle_written_inodeblock: live inodedep &status.unknown;   Found by stress tests at http://www.holm.cc/stress/log/cons142.html.
page fault at if_ethersubr.c: 284&status.wip;&status.done; &a.glebius; Found by stress tests at http://www.holm.cc/stress/log/cons141.html.
Alarming devfs shutdown error needs to be quenched &status.wip; &a.rwatson; During system shutdown, devfs generates a spurious error message due to /dev being non-unmountable: "unmount of /dev failed (BUSY)". While this is not a product of serious breakage, it is a potentially alarming error, whose source should either be fixed, or the message should be forceably quenched, in order to avoid many false positive bug reports and user concern.
panic: wrong b_bufobj &status.unknown; &a.jeff; Found by stress tests at http://www.holm.cc/stress/log/cons140.html. This is high priority and can be provoked within minutes of testing!
Livelock &status.unknown;   Found by stress tests at http://www.holm.cc/stress/log/cons139.html. This is the second most frequent panic reported by Peter Holm.
panic: softdep_setup_inomapdep: found inode &status.unknown;   Found by stress tests at http://www.holm.cc/stress/log/cons138.html.

Required features for 6.0-RELEASE

Issue Status Responsible Description
beastie.4th &status.wip; &a.scottl; Need to address the shortcomings of the old beastie.4th boot menu and hook it back into the boot process. This includes making the graphics easier to select and override, and making it use simple scrolling instead of ANSI screen addressing.

Desired features for 6.0-RELEASE

Issue Status Responsible Description
fpudna: fpcurthread == curthread 1 times &status.new; &a.peter; This warning is appearing sporadically on a dual AMD64 system. It appears to be warning against a legitimate problem, and thus should be investigated and fixed.
devfs umount panic &status.new;   There is a race condition between device removal and devfs umounts that causes "Memory modified after free" panics. Can be reproduced by doing 'mdconfig -u' concurrently with unmounting a devfs instance.
nullfs hash size &status.new;   Nullfs (and perhaps other filesystems) use an absurdly small hash size that causes significant performance penalties.
/dev/kmem panic &status.new;   Kris has noticed panics on SMP machines when there was ABI breakage of libkvm and world was not rebuilt and utilities like fstat were used. This suggests panics can be caused by incorrect accesses to /dev/kmem.
KLDs on sparc64 &status.new;   On sparc64 machines with more than 4Gb memory KLDs are not usable and will panic the system. The problem is reportedly with how the KLDs are compiled, it only works if the code ends up below 4G.
Max RAM on sparc64 &status.new;   Maximum RAM on sparc64 appears to be limited to 16Gb.
make -jN &status.new;   Doing 'make -jN', then suspending/resuming it may result in make reporting it lost child process(es).
kgdb on sparc64 &status.wip; &a.marcel; It looks like kgdb is still broken on sparc64. It is better than it used to be but still can't obtain a traceback. A fix was just committed to HEAD.
M_SAVEDINO &status.new;   A 'memory modified after free' bug affecting M_SAVEDINO. Possibly a softupdates bug.
OpenBSM &status.wip; &a.rwatson; The integration of OpenBSM is waiting on some final licensing hurdles. Once those are cleared, it will be a very desirable feature for 6.0.
update sysinstall disk labeling &status.new;   Sysinstall could use the same fixes recently made to fdisk so it plays nice with GEOM and disk labeling. This doesn't cause problems during install because nothing on the disk is mounted when its label is being manipulated but it can cause problems if sysinstall gets used on a live system to adjust labels on existing disks which sys-admins tend to do.

Documentation items that must be resolved for 6.0

Issue Status Responsible Description
dhclient &status.new; freebsd-doc The ISC DHCP client v3.x has been removed in favor of the OpenBSD DHCP client which was based on ISC DHCP v2.X. Minimal updates to the FreeBSD Handbook may be required.
WPA / hostap &status.new; freebsd-doc Significant new wireless functionality will be available with FreeBSD 6.0. The wireless section of the FreeBSD Handbook should be updated to describe how to connect to networks with WPA keys, setup host access points, etc.

Testing foci for 6.0-RELEASE

Issue Status Responsible Description
New dhclient &status.untested; &a.brooks; The ISC DHCP client v3.x has been removed in favor of the OpenBSD DHCP client which was based on ISC DHCP v2.X. More testing is needed to make sure there are no major regressions in functionality. We are particularly interested in tests involving non-standard environments.
WPA / hostap &status.untested; &a.sam; Significant new wireless functionality is available in FreeBSD 6.0. As this functionality is rather new, further testing would be appreciated.
if_bridge &status.untested;   A new bridge implementation has been added from NetBSD. As this has not seen a wider audience yet, further testing would be appreciated. See if_bridge(4) for configuration details.
sysinstall dhclient problems &status.untested; &a.scottl;, &a.sam; sysinstall has been updated to deal with the new DHCP client in 6.0, more testing is needed.
ULE &status.untested; &a.davidxu; The ULE scheduler has been fixed on both HEAD and RELENG_6. More testing is needed.
aac(4) regression &status.untested; &a.scottl; There had been a regression in the aac device driver on Dell 2550 machines. This should be fixed but more testing would be good.
vnode_pager_init nswbuf initialization bug &status.untested; &a.kan; There had been a serious performance regression due to a very low bound on the number of swap buffers per vnode (1). This should be fixed but more testing would be good.
fdisk & boot0cfg &status.untested; &a.phk; The boot0cfg and fdisk utilities need to be updated to use the proper GEOM model for updating the boot sector of a mounted disk.

Stress Test Panics

The system is continuously being subjected to Peter Holm's Kernel Stress Test Suite. The following issues have recently been discovered from this test suite.
