Must Resolve Issues for 5.1-RELEASE +------------------------------------------------------------------------+ | Issue | Status | Responsible | Description | |------------------+----------+-------------+----------------------------| | | | | Kris Kennaway reports that | | | | | he has seen several unique | | | | | panics on the alpha | | Spurious alpha | | | machines, but since gdb -k | | panics | -- | -- | doesn't work on alpha I | | | | | haven't been able to get | | | | | more than a DDB traceback. | | | | | No-one has looked into | | | | | them. | |------------------+----------+-------------+----------------------------| | gdb -k doesn't | -- | Mark Peek | gdb -k doesn't work on | | work on alpha | | | alpha | |------------------+----------+-------------+----------------------------| | | | | There are reports of | | ipfw/ipfw2 | | | alignment problems with | | alignment issues | In | Luigi Rizzo | ipfw and/or ipfw2 on | | on alpha/sparc64 | progress | | 64-bit platforms | | | | | (specifically alpha and | | | | | sparc64). | |------------------+----------+-------------+----------------------------| | | | | Kris Kennaway reports high | | | | | instability of 5.0-CURRENT | | | | | on ia64 machines, such as | | ia64 stability | -- | -- | the pluto* machines. These | | | | | problems need to be fixed | | | | | in order to get a | | | | | successful package build. | |------------------+----------+-------------+----------------------------| | | | | Kris Kennaway reports that | | | | | there is a gcc bug on | | | | | sparc64 that prevents the | | gcc sparc64 | -- | -- | build of | | problems | | | XFree86-4-libraries. | | | | | Alexander Kabaev is | | | | | working on a gcc 3.3 | | | | | patchset for test. | |------------------+----------+-------------+----------------------------| | | | | ia64 serial console | | | | | support is not currently | | | In | Marcel | functional, and requires a | | ia64 sio support | progress | Moolenaar, | reworking of the sio | | | | Warner Losh | support to improve | | | | | platform independence and | | | | | bus handling. | |------------------+----------+-------------+----------------------------| | | | | Brian Feldman has | | | | | submitted patches to | | | | | improve the consistency of | | MAC Framework | In | Robert | the pathnames passed into | | devfs path fixes | progress | Watson | the MAC Framework devfs | | | | | labeling entry points. | | | | | These patches need to be | | | | | thoroughly reviewed and | | | | | tested, then merged. | |------------------+----------+-------------+----------------------------| | | | | MAC Framework | | | | | synchronization currently | | | | | costs two mutex lock and | | | | | unlock operations for each | | MAC Framework | | | entry point, even if no | | locking | In | Robert | dynamically | | performance | progress | Watson | loadable/unloadable | | improvements | | | policies are present. | | | | | Patches are currently | | | | | being tested that halve | | | | | this locking cost when | | | | | dynamic policies are not | | | | | loaded. | |------------------+----------+-------------+----------------------------| | Panic on | | | If a network device | | load/unload a | | | driver, possibly any | | kernel module | | | driver, is linked into the | | for a driver | -- | -- | kernel and then loaded and | | already | | | unloaded as a module, the | | statically | | | kernel will panic. This | | linked into the | | | has been observed with | | kernel. | | | both if_dc and if_fxp. | +------------------------------------------------------------------------+ Desired Features for 5.1-RELEASE +------------------------------------------------------------------------+ | Issue | Status | Responsible | Description | |-----------------+-----------+------------------+-----------------------| | | | | A.out support in the | | | | | base system was | | a.out 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 | | | | | debugged. A bug also | | Race conditions | Errata | | appears to exist | | in truss | candidate | Robert Drehmel | 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. The fix for | | | | | this sufficiently | | | | | changes process | | | | | execution handling | | | | | that we will defer | | | | | the fix to post-5.0 | | | | | and consider this | | | | | errata. | |-----------------+-----------+------------------+-----------------------| | | | | Currently, the MD | | | | | elements of KSE are | | | | | present only for the | | | | | i386 platform, | | | | | limiting use of KSE | | | | | to the i386 platform. | | | | | It is highly | | KSE support for | | | desirable to make KSE | | sparc64, alpha, | -- | Jake Burkholder, | available 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 | -- | -- | link editor (rtld) | | thread-safety | | | thread-safe with | | | | | libpthread. | |-----------------+-----------+------------------+-----------------------| | | | | Kris Kennaway reports | | | | | deadlocks involving | | | | | the use of nullfs in | | | | | the bento | | | | | environment: | | | | | buildworld -j4 with | | nullfs | | | src and obj mounted | | deadlocks | -- | -- | via nullfs; the gcc | | | | | processes eventually | | | | | deadlocked in the ufs | | | | | state. DDB traceback | | | | | showed two different | | | | | codepaths. I've just | | | | | repeated this, so the | | | | | bug still exists. | +------------------------------------------------------------------------+ Documentation items that must be resolved for 5.1 +------------------------------------------------------------------------+ | Issue | Status | Responsible | Description | |-----------------+-------------+--------------+-------------------------| | | | | We now use OPIE instead | | Documentation | | Christian | of S/Key. The handbook | | rottage: S/Key | In progress | Brueffer | doesn't cover OPIE as | | | | | well as it covers | | | | | S/Key. | |-----------------+-------------+--------------+-------------------------| | | | | The hardware notes for | | | | | ia64 needs some large | | ia64 Hardware | -- | -- | 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. | +------------------------------------------------------------------------+ Areas requiring immediate testing +------------------------------------------------------------------------+ | Issue | Status | Responsible | Description | |-----------------+-----------+-----------------+------------------------| | | | | The 20030228 vendor | | Fresh ACPI-CA | | | sources have been | | import | -- | -- | imported. Further | | | | | testing is | | | | | appreciated. | |-----------------+-----------+-----------------+------------------------| | | | | During the install, | | | | | the iir controller | | | | | appears to correctly | | | | | probe, but finds no | | | | | disk devices. The card | | | | | in question is an | | | | | Intel srcu32 RAID | | iir driver | | | controller with 32Mb | | fails to probe | -- | -- | RAM, Firmware revision | | disks | | | 2.33.01. Intel | | | | | developers have | | | | | released an update | | | | | driver, which has | | | | | recently been adapted | | | | | and imported into | | | | | 5-CURRENT, and must be | | | | | tested. | |-----------------+-----------+-----------------+------------------------| | | | | PAE support allows the | | | | | use of up to 64GB of | | PAE support for | | | RAM on Pentium Pro and | | i386 | -- | -- | above systems. Virtual | | | | | addresses are still | | | | | constrained to | | | | | 32-bits. | |-----------------+-----------+-----------------+------------------------| | | | | The recently upgraded | | | | | if_wi driver is more | | | | | tuned to Prism | | | | | hardware than to | | if_wi problems | | | Lucent hardware, | | on Lucent | -- | -- | resulting in system | | hardware | | | lockups and poor | | | | | performance when using | | | | | Lucent hardware. These | | | | | problems are believed | | | | | to be fixed but more | | | | | testing is welcome. | |-----------------+-----------+-----------------+------------------------| | | | | There are reports that | | | | | kernels build with | | No console | | | smbus, viapm, and smb | | (term) if smbus | -- | -- | devices may not | | is enable in | | | properly probe and | | the kernel | | | support the system | | | | | console following | | | | | boot. | |-----------------+-----------+-----------------+------------------------| | | | | For 5.1-RELEASE, the | | | | | default file system | | | | | type for newly created | | | | | file systems is UFS2 | | | | | rather than UFS1. | | UFS2 as | | | newfs(8) and | | installation, | -- | Robert Watson | sysinstall(8) have | | newfs default | | | been updated to use | | | | | this new default. | | | | | Testing to make sure | | | | | all goes well after | | | | | the change (committed | | | | | on April 20, 2003) is | | | | | vital. | |-----------------+-----------+-----------------+------------------------| | | | | Kris Kennaway reports | | | | | mutex panics in wait4 | | | | | in the bento | | | | | environment: | | wait4 | | | "Impossible" mutex | | "impossible" | -- | Tim J. Robbins | panic in wait4() | | mutex panic | | | (reported to -current | | | | | a while ago). Believed | | | | | to be related to (and | | | | | fixed along with) | | | | | uidinfo "impossible" | | | | | panic below. | |-----------------+-----------+-----------------+------------------------| | | | | Kris Kennaway reports | | | | | that there appears to | | | | | be a resource leak of | | | | | uidinfo reference | | uidinfo | | | counts that is causing | | "impossible" | -- | Tim J. Robbins | the gohan machines to | | panic | | | panic after about 18 | | | | | days of load. | | | | | Tim J. Robbins has | | | | | committed a fix that | | | | | is believed to solve | | | | | the problem. | |-----------------+-----------+-----------------+------------------------| | | | | Support for pluggable | | | | | directory services | | | | | using NSS, including | | | | | adaptations of current | | | | | directory services | | NSSwitch | | | (local databases, | | support | -- | Jacques Vidrine | NIS), and support for | | | | | new services (LDAP, | | | | | Active Directory, | | | | | etc). This change has | | | | | been committed, and | | | | | requires broader | | | | | testing. | |-----------------+-----------+-----------------+------------------------| | | | | Starting in late | | | | | April, reports of a | | | | | new UFS panic, "panic: | | | | | ffs_blkfree: freeing | | | | | free frag" began to | | | | | pop up with a high | | | | | frequency in some | | | | | environments. This | | | | | problem appears to | | | | | have been associated | | | | | with a bug introduced | | | | | in the VM system that | | | | | has now been resolved. | | panic: | Patch | Alan L. Cox | Users who updated to a | | ffs_blkfree | committed | | kernel between | | | | | approximately May 1 | | | | | and May 4 will want to | | | | | run a full foreground | | | | | fsck on all file | | | | | systems to make sure | | | | | that no remaining free | | | | | space accounting | | | | | errors exist. However, | | | | | we should be on the | | | | | lookout for any | | | | | recurrence of this | | | | | problem due to its | | | | | serious nature. | |-----------------+-----------+-----------------+------------------------| | | | | Due to TCP state | | | | | efficiency | | | | | improvements in the | | | | | TIMEWAIT state, it is | | | | | now possible for the | | | | | PCB socket pointer to | | | | | be NULL in situations | | TIMEWAIT panic | | | it previously wasn't. | | for network | Patch | | As a result, TCP | | labeled MAC | committed | Robert Watson | responses generated in | | policy modules | | | the TIMEWAIT state | | | | | lacked properly | | | | | initialized MAC | | | | | labels, resulting in | | | | | panics for network | | | | | labeled MAC policies. | | | | | A fix has been | | | | | committed, and needs | | | | | more broad testing. | +------------------------------------------------------------------------+ ---------------------------------------------------------------------- freebsd-qa_at_FreeBSD.ORG Copyright (c) 1995-2003 The FreeBSD Project.
