This is a list of open issues that need to be resolved for FreeBSD
5.0. If you have any updates for this list, please e-mail
re@FreeBSD.org.
| Issue | Status | Responsible | Description |
|---|
| Audit of devfs device permissions |
In progress |
kris@ |
With the move to devfs, the permissions specified in kernel device
creation lines using make_dev() are now used as the default permissions
for /dev entries. Some of these entries are more lax than is desired,
or than the MAKEDEV defaults in 4.x. These need to be carefully
reviewed and fixed. |
| Race conditions in truss |
Debugging and fixing in progress |
robert@ |
Truss appears to contain a race condition during the start-up of
debugging, which can result in truss failing to attach to the process
before it exits. The symptom is that truss reports that it cannot
open the procfs node supporting the process being debugged. A bug
also appears to exist where in truss will hang if execve() returns
ENOENT. A further race appears to exist in which truss will return
"PIOCWAIT: Input/output error" occasionally on startup. |
| Many reported problems with disklabel -e |
-- |
phk@, jhb@ |
Changes in the disk label format have resulted in substantial
numbers of bug reports; these must be resolved by RC1. The problem
involving a cache coherency issue relating to partition resizes
has now been resolved. Problems relating to disklabel -r and
the change appear to continue. |
-
- | Reported problems with fdisk disk editor |
- Patches circulating |
- jhb@,nyan@ |
- Reported problems deleting non-FreeBSD slices using the sysinstall
- fdisk editor. |

| inpcb panic involving IP stack sleep |
Debugging in progress |
mux@ |
Report of a panic in the TCP syncache thread under load, due to
another thread sleeping while holding an inpcb mutex, when not
running with WITNESS (WITNESS would have caught the sleep earlier).
|
| mly driver hangs during install |
-- |
scottl@, jeff@ |
Hangs have been reported during the 5.0 snapshot install when
installing to mly supported RAID arrays. The same array appears
to work fine with 4.7-RELEASE. The card in question is a Mylex
AcceleRAID 170, 32 Mb RAM, Firmware revision 7.01-00. This is
believed to be the same problem as described in PR 45383. |
| iir driver fails to probe disks |
-- |
-- |
During the install, the iir controller appears to correctly
probe, but finds no disk devices. The card in question is an
Intel srcu32 RAID controller with 32Mb RAM, Firmware revision
2.33.01 |
| Need to disable rare ISA drivers via hints |
-- |
jhb@ |
ISA driver probes for rare drivers can be disruptive, and should
be disabled. |
| syscons hangs on SMP systems |
-- |
scottl@ |
There are reports of output hangs for syscons on SMP boxes,
which may involve a failure of the timeout() update of the
system display. The system appears to be otherwise functional. |

| 5.0 Documentation | -- | freebsd-doc |
As a minimum, we need to cover the areas where 5.x and 4.x
differ in the FAQ and Handbook. This entails marking some areas
with "This procedure is specific to 4.X. For more information for
5.x, please see foo(n)" or similar. This needs to happen quickly,
to give adequate time for the translation teams to catch up. |
| Disable performance penalizing debug options |
Pending RC1 |
re@ |
A number of performance-penalizing debug options are turned on
by default in 5.0-CURRENT. These include user malloc debugging
flags, WITNESS, INVARIANTS, DEBUG=-g, and others. These must be
turned off as we approach the release. |
| Disable verbose debug options |
Pending RC2 |
re@ |
By default, ACPI generates verbose bus dumps during initial
boot even if verbose it turned off. Libdisk also includes
the DEBUG define by default, resulting in additional output.
This output needs to be turned down following RC2. |
| devd | Prototype committed. |
imp@ | A devd prototype has been committed;
will mature as we approach the 5.0 release, including adopting
a mature configuration format. |
| TrustedBSD MAC Framework userland applications |
Mostly merged, some minor updates pending |
rwatson@ |
Most MAC support for user applications and daemons has been
merged. Minor updates to support correct labeling in inetd,
optional labeling of ttys, and a few other bits and pieces are
pending. |
| TrustedBSD MAC Framework documentation |
FreeBSD documentation CVS HEAD: in progress |
chris@ | User and developer documentation of
the new extensible security framework. Includes guides for live
deployment, development of policy modules, and implementation
information. |
| Port of LOMAC to TrustedBSD MAC Framework |
Merge in progress |
green@,rwatson@ |
New mac_lomac implementation almost completely merged:
currently missing are the default policy file (commit request
under review by re@) and documentation. |
| UFS2 bootable on i386 |
In progress. We might want to miss on this one. |
phk@ |
UFS2 can be successfully booted on sparc64, but on i386
boot2 cannot fit in the space reserved in front of a UFS1 filesystem.
disklabel, libdisk, sysinstall and newfs needs to learn about this
wrinkle, and we need some makefile magic to build both UFS1 and
UFS1/2 boot2 boot files.
The potential for foot-shooting is very large, and phk@ currently
leans towards defaulting to UFS1 for root and boot, and UFS2 for
all other filesystems.
|
| sysinstall support for UFS2 |
Patches being circulated. |
rwatson@ |
Teach sysinstall how to properly create UFS2 partitions, and
under what circumstances that is appropriate. |
| KerberosV, OpenSSH, and PAM |
In progress |
markm@, des@, nectar@ |
KerberosV appears not to currently work with OpenSSH using PAM.
Bugs relating to pam_kerberosV have in large part been fixed. |
| FireWire Support |
In progress |
simokawa@ |
Firewire kernel support has been committed. Userland support is
pending. Large quantities of debugging output are reported;
may require an "experimental feature tag" for the release notes? |
| Proc Locking | Patches available in Perforce |
jhb@ | Further locking cleanups relating to
p_ucred. |
| awk(1) locale support |
Pending import of new one-true-awk |
obrien@ |
awk(1) should be fixed to respect locale |
| No console (term) if smbus is enable in the kernel |
-- |
-- |
There are reports that kernels build with smbus, viapm, and smb
devices may not properly probe and support the system console
following boot. |
| Convert base system utilities that rely on Perl |
-- |
markm |
With perl removed from the base system in 5.0, any existing
dependencies on perl must also be converted to a native shell
scripting language, C, or be made into packages or ports.
Remaining base system tools include mmroff, afmtodit. |
| Issue | Status | Responsible | Description |
|---|
| User documentation for ACPI. |
-- |
freebsd-doc@ |
The new ACPI code is a very important component of FreeBSD
5.0-RELEASE, but the documentation is insufficient. The manual
page does not describe how to perform the basic ACPI tasks. The
Usenix paper, man pages, and mailing list archives should be used
to write a substantial new section to the FreeBSD Handbook. New
users read the Handbook. See PR 43528. |
| a.out toolchain port |
-- |
-- |
A.out support in the base system was reduced; the removed build
chain components should be made into a port. |
| Rename of local -> unix in rpc socket names |
-- |
mbr@ |
mbr has requested that we change from using "local" to "unix"
for tirpc unix domain socket transport naming, to sync to NetBSD. |
| OpenSSH reports lastlog warning |
-- |
des@ |
OpenSSH appears to invoke the PAM session code in the wrong process
when running with privsep, resulting in warnings of the form
"Nov 20 18:08:55 u60 sshd[2002]: /var/log/lastlog: Permission denied".
This may be a bug that requires reworking OpenSSH to work properly
with PAM, but should be resolved in some form for the release. |
| NETNCP and nwfs broken |
-- |
-- |
NETNCP and nwfs appear to be as-yet unadapted for KSE, and hence
not working. The build needs fixing (probably not all that hard)
and then it needs to be tested (harder: few people appear to have
Netware servers). |
| No docs for FAST IPSEC |
-- |
-- |
The new "fast ipsec" implementation has insufficient documentation
(man pages, release notes), and this would be highly desirable to
have before 5.0-RELEASE. |
| gdb for sparc64 |
-- |
tmm@ |
gdb 5.3 now works with sparc64; gdb import desired. |
| live file system boot0cfg |
-- |
-- |
boot0cfg -s on a live file system now no longer functions. It
would be highly desirable for this, and related functionality, to
work. |
| SMP documentation update |
-- |
-- |
smp(4) and other bits of system documentation relating to SMP
are dated since to introduction of SMPng, MP support on sparc64,
alpha, and ia64. These documents should be updated. In addition,
the SMPng draft architecture should be updated and committed. |
