Must Resolve Issues for 5.1-RELEASE
+------------------------------------------------------------------------+
| Issue | Status | Responsible | Description |
|-------------------+-------------+---------------+----------------------|
| | | | There are reports of |
| | | | alignment problems |
| ipfw/ipfw2 | | | with ipfw and/or |
| alignment issues | In progress | Luigi Rizzo | ipfw2 on 64-bit |
| on alpha/sparc64 | | | platforms |
| | | | (specifically alpha |
| | | | and sparc64). |
|-------------------+-------------+---------------+----------------------|
| | | | Kris Kennaway |
| | | | reports high |
| | | | instability of |
| | | | 5.0-CURRENT on ia64 |
| ia64 stability | -- | -- | machines, such as |
| | | | the pluto* machines. |
| | | | These problems need |
| | | | to be fixed in order |
| | | | to get a successful |
| | | | package build. |
|-------------------+-------------+---------------+----------------------|
| | | | Brian Feldman has |
| | | | submitted patches to |
| | | | improve the |
| | | | consistency of the |
| | | | pathnames passed |
| MAC Framework | | | into the MAC |
| devfs path fixes | In progress | Robert Watson | Framework devfs |
| | | | labeling entry |
| | | | points. These |
| | | | patches need to be |
| | | | thoroughly reviewed |
| | | | and tested, then |
| | | | merged. |
|-------------------+-------------+---------------+----------------------|
| | | | If a network device |
| | | | driver, possibly any |
| Panic on | | | driver, is linked |
| load/unload a | | | into the kernel and |
| kernel module for | Patch | Maxime | then loaded and |
| a driver already | submitted | Henrion | unloaded as a |
| statically linked | | | module, the kernel |
| into the kernel. | | | will panic. This has |
| | | | been observed with |
| | | | both if_dc and |
| | | | if_fxp. |
|-------------------+-------------+---------------+----------------------|
| | | | Currently, the MD |
| | | | elements of KSE are |
| | | | present only for the |
| | | | i386 platform, |
| | | | limiting use of KSE |
| | | | to the i386 |
| | | | platform. It is |
| | | | highly desirable to |
| KSE support for | | Jake | make KSE available |
| sparc64, alpha, | -- | Burkholder, | on non-i386 |
| ia64 | | --, -- | platforms for |
| | | | 5.1-RELEASE so that |
| | | | KSE can see more |
| | | | broad exposure, and |
| | | | the performance |
| | | | benefits of KSE can |
| | | | be visible to users |
| | | | of the 64-bit |
| | | | FreeBSD |
| | | | architectures. |
|-------------------+-------------+---------------+----------------------|
| | | | Update the run-time |
| rtld-elf | -- | Alexander | link editor (rtld) |
| thread-safety | | Kabaev | thread-safe with |
| | | | libpthread. |
|-------------------+-------------+---------------+----------------------|
| | | | rpc.lockd(8) |
| | | | client-side and |
| | | | server-side NFS |
| | | | locking appears to |
| | | | have a number of |
| | | | serious bugs which |
| rpc.lockd(8) | | | prevent NFS locking |
| stability | In progress | Robert Watson | from working |
| | | | properly in a number |
| | | | of common scenarios. |
| | | | These bugs must be |
| | | | resolved to ship |
| | | | 5.1-RELEASE. Work is |
| | | | underway to classify |
| | | | and track the bugs. |
|-------------------+-------------+---------------+----------------------|
| | | | There have been |
| | | | reports of |
| | | | memory/data |
| | | | corruption on some |
| | | | systems; one working |
| | | | hypothesis is that |
| | | | this corresponds to |
| | | | an undocumented bug |
| | | | in a particular line |
| | | | of Intel and AMD |
| data corruption | | Peter Wemm, | processors, but it's |
| reports | In progress | Bosko Milekic | unclear whether |
| | | | current work-arounds |
| | | | are correcting or |
| | | | masking the problem. |
| | | | Patches are being |
| | | | circulated to test |
| | | | this hypothesis, but |
| | | | developers are |
| | | | encouraged to be on |
| | | | the lookout for |
| | | | possible data |
| | | | corruption bugs. |
+------------------------------------------------------------------------+
Desired Features for 5.1-RELEASE
+------------------------------------------------------------------------+
| Issue | Status | Responsible | Description |
|---------------+-------------+----------------+-------------------------|
| | | | ia64 serial console |
| | | | support is reported to |
| | | | not be functional on HP |
| ia64 sio | | Marcel | Itanium2 platforms. A |
| support | In progress | Moolenaar, | reworking of the sio |
| | | Warner Losh | driver to improve |
| | | | platform independence |
| | | | and bus handling is |
| | | | likely needed. |
|---------------+-------------+----------------+-------------------------|
| | | | A.out support in the |
| a.out | | | base system was |
| toolchain | -- | -- | reduced; the removed |
| port | | | build chain components |
| | | | should be made into a |
| | | | port. |
|---------------+-------------+----------------+-------------------------|
| | | | 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 |
| Race | | | debugged. A bug also |
| conditions in | Errata | Robert Drehmel | appears to exist where |
| truss | candidate | | 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. The fix for |
| | | | this sufficiently |
| | | | changes process |
| | | | execution handling that |
| | | | we will defer the fix |
| | | | to post-5.0 and |
| | | | consider this errata. |
|---------------+-------------+----------------+-------------------------|
| | | | Kris Kennaway reports |
| | | | deadlocks involving the |
| | | | use of nullfs in the |
| | | | bento environment: |
| | | | buildworld -j4 with src |
| | | | and obj mounted via |
| nullfs | -- | -- | nullfs; the gcc |
| deadlocks | | | processes eventually |
| | | | deadlocked in the ufs |
| | | | state. DDB traceback |
| | | | showed two different |
| | | | codepaths. I've just |
| | | | repeated this, so the |
| | | | bug still exists. |
|---------------+-------------+----------------+-------------------------|
| | | | If amd(8) does mount |
| | | | more than one fs from a |
| | | | host, the second call |
| | | | to mountd on the server |
| | | | gets aborted even if |
| | | | the read does return |
| | | | EAGAIN. This is |
| | | | definitly a bug in the |
| | | | nonblocking rpc code. |
| amd/mountd | In progress | Martin Blapp | If truss or ktrace is |
| bugs | | | attached on mountd, the |
| | | | bug happens almost all |
| | | | times, else 3-10 times |
| | | | of 10 trys. Since there |
| | | | have been several |
| | | | reports of amd |
| | | | irregularity on |
| | | | 5.1-BETA, it's |
| | | | important to get this |
| | | | fixed for the release. |
|---------------+-------------+----------------+-------------------------|
| gdb -k | | | gdb -k doesn't work on |
| doesn't work | -- | Mark Peek | alpha |

Documentation items that must be resolved for 5.1
+------------------------------------------------------------------------+
| Issue | Status | Responsible | Description |
|-----------------+-------------+--------------+-------------------------|
| | | | The hardware notes for |
| | | | ia64 needs some large |
| ia64 Hardware | In progress | Jim Brown | infusions of text. They |
| Notes | | | probably haven't been |
| | | | synched with reality |
| | | | for awhile. |
|-----------------+-------------+--------------+-------------------------|
| | | | As BUSDMA is now the |
| | | | required driver API for |
| | | | DMA access in hardware |
| | | | device drivers as of |
| | | | 5.1-RELEASE, we need to |
| busdma man page | In progress | Hiten Pandya | make sure it's properly |
| | | | documented. A man page |
| | | | is in progress and |
| | | | needs to be |
| | | | appropriately reviewed |
| | | | and committed prior to |
| | | | the release. |
|-----------------+-------------+--------------+-------------------------|
| | | | rcNG is now the |
| | | | supported (and only) |
| | | | boot scripting |
| rcNG | | | mechanism in 5.x, but |
| documentation | In progress | Tom Rhodes | it's not currently |
| | | | documented in the |
| | | | handbook. We need this |
| | | | documentation for |
| | | | 5.1-RELEASE. |
+------------------------------------------------------------------------+
Areas requiring immediate testing
+------------------------------------------------------------------------+
| Issue | Status | Responsible | Description |
|-------------------+--------+---------------+---------------------------|
| | | | The 20030228 vendor |
| Fresh ACPI-CA | -- | -- | sources have been |
| import | | | imported. Further testing |
| | | | is appreciated. |
|-------------------+--------+---------------+---------------------------|
| | | | PAE support allows the |
| | | | use of up to 64GB of RAM |
| PAE support for | -- | -- | on Pentium Pro and above |
| i386 | | | systems. Virtual |
| | | | addresses are still |
| | | | constrained to 32-bits. |
|-------------------+--------+---------------+---------------------------|
| | | | The recently upgraded |
| | | | if_wi driver is more |
| | | | tuned to Prism hardware |
| | | | than to Lucent hardware, |
| if_wi problems on | | | resulting in system |
| Lucent hardware | -- | -- | lockups and poor |
| | | | performance when using |
| | | | Lucent hardware. These |
| | | | problems are believed to |
| | | | be fixed but more testing |
| | | | is welcome. |
|-------------------+--------+---------------+---------------------------|
| | | | For 5.1-RELEASE, the |
| | | | default file system type |
| | | | for newly created file |
| | | | systems is UFS2 rather |
| UFS2 as | | | than UFS1. newfs(8) and |
| installation, | -- | Robert Watson | sysinstall(8) have been |
| newfs default | | | updated to use this new |
| | | | default. Testing to make |
| | | | sure all goes well after |
| | | | the change (committed on |
| | | | April 20, 2003) is vital. |
|-------------------+--------+---------------+---------------------------|
| | | | Support for pluggable |
| | | | directory services using |
| | | | NSS, including |
| | | | adaptations of current |
| | | Jacques | directory services (local |
| NSSwitch support | -- | Vidrine | databases, NIS), and |
| | | | support for new services |
| | | | (LDAP, Active Directory, |
| | | | etc). This change has |
| | | | been committed, and |
| | | | requires broader testing. |
|-------------------+--------+---------------+---------------------------|
| | | | Kris Kennaway reports |
| | | | that he has seen several |
| | | | unique panics on the |
| Spurious alpha | | | alpha machines, but since |
| panics | -- | -- | gdb -k doesn't work on |
| | | | alpha I haven't been able |
| | | | to get more than a DDB |
| | | | traceback. No-one has |
| | | | looked into them. |
