Issues that require investigation +------------------------------------------------------------------------+ | Issue | Status | Responsible | Description | +------------------------------------------------------------------------+ Show stopper defects for 5.3-RELEASE +------------------------------------------------------------------------+ | Issue | Status | Responsible | Description | +------------------------------------------------------------------------+ Required features for 5.3-RELEASE +------------------------------------------------------------------------+ | Issue | Status | Responsible | Description | +------------------------------------------------------------------------+ Desired features and bugfixes for 5.3-RELEASE +------------------------------------------------------------------------+ | Issue | Status | Responsible | Description | |------------------+-------------+----------------+----------------------| | | | | There have been | | | | | reports that | | | | | specific gigabit | | | | | ethernet cards | | | | | supported by the | | | | | if_re driver are | | Reports of poor | | | experiencing poor | | performance with | | | performance; a patch | | the if_re driver | In progress | John-Mark | has been posted that | | (re ethernet | | Gurney | corrects timer and | | interfaces) | | | interrupt problems | | | | | with the driver, and | | | | | is believed to | | | | | correct the | | | | | performace problems. | | | | | The patch will be | | | | | merged to 6.x and | | | | | 5.x shortly. | |------------------+-------------+----------------+----------------------| | | | | With improved | | | | | support for | | | | | threading | | | | | primitives, support | | | | | is now required to | | GDB thread | | David Xu, | ease debugging of | | support | In progress | Marcel | threaded | | | | Moolenaar | applications. | | | | | Ideally, this | | | | | support will work | | | | | for both libthr and | | | | | libkse threading | | | | | models. | |------------------+-------------+----------------+----------------------| | | | | Kernel bits | | KSE support for | In progress | Ken Smith | implemented, | | sparc64 | | | userland not | | | | | implemented. | |------------------+-------------+----------------+----------------------| | | | | Almost all process | | | | | debugging tools have | | | | | been updated to use | | | | | non-procfs kernel | | | | | primitives, with the | | | | | exception of | | | | | truss(1). As procfs | | | | | is considered | | | | | deprecated due to | | | | | its inherent | | | | | security risks, it | | truss support | | | is highly desirable | | for ptrace | -- | -- | to update truss to | | | | | operate in a | | | | | post-procfs world. | | | | | Dag-Erling Smorgrav | | | | | had prototype | | | | | patches; | | | | | Robert Drehmel is | | | | | developing and | | | | | testing patches now. | | | | | Support for system | | | | | call tracing has | | | | | been added to | | | | | ptrace(). | |------------------+-------------+----------------+----------------------| | | | | FAST_IPSEC currently | | | | | cannot be used | | | | | directly with the | | | | | KAME IPv6 | | | | | implementation, | | | | | requiring an | | | | | additional level of | | | | | IP tunnel | | | | | indirection to | | | | | protect IPv6 packets | | FAST_IPSEC and | | | when using hardware | | KAME | Not done | -- | crypto acceleration. | | compatibility | | | This issue must be | | | | | resolved so that the | | | | | two services may | | | | | more easily be used | | | | | together. Among | | | | | other things, this | | | | | will require a | | | | | careful review of | | | | | the handling of mbuf | | | | | header copying and | | | | | m_tag support in the | | | | | KAME IPv6 code. | |------------------+-------------+----------------+----------------------| | | | | A process cannot be | | | | | interrupted while | | | | | waiting on a lock. | | rpc.lockd(8) | | | Fixing this requires | | stability | -- | -- | that the RPC code be | | | | | taught how to deal | | | | | with lock | | | | | cancellation and | | | | | interruption events. | |------------------+-------------+----------------+----------------------| | | | | Kernel modules are | | | | | currently built | | | | | independently from a | | | | | kernel | | | | | configuration, and | | | | | independently from | | | | | one another, | | | | | resulting in | | | | | substantially | | | | | redundant | | | | | compilation of | | | | | objects, as well as | | | | | the inability to | | | | | easily manage | | | | | compile-time options | | Revised kld | | | for kernel objects | | build | Not done | Peter Wemm | (such as MAC, PAE, | | infrastructure | | | etc) that may | | | | | require conditional | | | | | compilation in the | | | | | kernel modules. In | | | | | order to improve | | | | | build performance | | | | | and better support | | | | | options of this | | | | | sort, the KLD build | | | | | infrastructure needs | | | | | to be revamped. | | | | | Peter Wemm has done | | | | | some initial | | | | | prototyping, and | | | | | should be contacted | | | | | before starting on | | | | | this work. | |------------------+-------------+----------------+----------------------| | | | | 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 | Robert Drehmel | appears to exist | | in truss | candidate | | 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. | |------------------+-------------+----------------+----------------------| | | | | The LOR reported in | | | | | PR kern/55175 needs | | filedesc LOR | Not done | -- | to be fixed. | | | | | Filedesc locking | | | | | needs to be heavily | | | | | reviewed in general. | |------------------+-------------+----------------+----------------------| | | | | Userland bits | | KSE support for | In progress | Marcel | implemented, kernel | | alpha | | Moolenaar | bits not | | | | | implemented. | |------------------+-------------+----------------+----------------------| | | | | For kernel API/ABI | | | | | compatibility | | | | | reasons, it would be | | CAM locking | In progress | Scott Long, | desirable to have | | | | Justin Gibbs | the CAM locking | | | | | strategy determined | | | | | and loosely | | | | | implemented for 5.3. | |------------------+-------------+----------------+----------------------| | | | | When running syscons | | | | | on an Ultra-30 with | | | | | Creator-3D typing | | | | | characters on the | | | | | keyboard produces | | | | | garbage.

All Tier-1 | | | | | platforms MUST | | | | | have stable KSE | | KSE as the | | David Xu, | support for 5.3 in | | default threads | Needs testing | Daniel | order to support a | | library | | Eischen | consistent | | | | | transition. | | | | | Additionally, all | | | | | ports that depend | | | | | on the pthreads | | | | | API must be | | | | | modified to | | | | | properly detect | | | | | and support the | | | | | default threading | | | | | library. | |-------------------+---------------+---------------+--------------------| | | | | Binutils needs | | | | | updating in order | | Updated binutils | | | to support new | | for all platforms | Needs testing | David O'Brien | platforms, newer | | | | | GDB versions, and | | | | | Thread Local | | | | | Storage. | |-------------------+---------------+---------------+--------------------| | | | | The previous GCC | | | | | 3.3 snapshot | | | | | included | | | | | regressions in | | | | | alignment of | | | | | floating point | | gcc 3.3 floating | | | arguments, | | point alignment | Needs testing | | resulting in a | | regression | | | substantial | | | | | performance | | | | | degradation. The | | | | | recent GCC 3.4.2 | | | | | import should fix | | | | | this, but more | | | | | testing is needed. | |-------------------+---------------+---------------+--------------------| | | | | Jun Kuriyama has | | | | | reported a failed | | | | | locking assertion | | in6_pcbnotify() | Done | Robert Watson | with IPv6 TCP | | panic with TCP | | | notifications. | | | | | This problem is | | | | | believed to be | | | | | corrected. | |-------------------+---------------+---------------+--------------------| | | | | To complete | | | | | support for | | | | | thread-local | | | | | storage on | | | | | FreeBSD, | | Per-platform | | Doug Rabson, | per-architecture | | Thread-Local | Needs testing | Marcel | changes must be | | Storage | | Moolenaar | made. Currently | | | | | pending platforms | | | | | are amd64, alpha, | | | | | ia64, i386, | | | | | sparc64, and | | | | | powerpc. | |-------------------+---------------+---------------+--------------------| | | | | High load on SMP | | | | | systems appears to | | | | | result in a hard | | | | | hang related to VM | | | | | IPI. Doug White | | SMP instability | | Doug White, | has prepared a | | under load | Needs testing | Alan L. Cox | candidate patch | | | | | that appears to | | | | | resolve this | | | | | instability, which | | | | | is currently in | | | | | testing for merge | | | | | to the CVS HEAD. | |-------------------+---------------+---------------+--------------------| | | | | Significant parts | | | | | of the network | | | | | stack (especially | | | | | IPv4, UNIX domain | | | | | IPC, and sockets) | | | | | now have | | | | | fine-grained | | | | | locking of their | | | | | data structures. | | | | | It's possible to | | | | | run many common | | | | | network subsystems | | | | | and services | | | | | without the Giant | | Fine-grained | | | lock. However, a | | network stack | | | number of device | | locking without | Needs testing | Robert Watson | drivers and less | | Giant | | | mainstream network | | | | | subsystems are | | | | | currently not | | | | | MPSAFE. 5.3 betas | | | | | have shipped with | | | | | Giant-free | | | | | networking by | | | | | default, with some | | | | | bug reports and | | | | | fixes in later | | | | | betas and release | | | | | candidates. Please | | | | | report any | | | | | problems to the | | | | | current_at_ mailing | | | | | list. | |-------------------+---------------+---------------+--------------------| | | | | KLDs work when | | | | | loaded from | | | | | userland, but not | | | | David | from the loader. | | kld support for | Needs testing | O'Brien, Ian | kldxref and loader | | amd64 | | Dowse | support has been | | | | | committed to HEAD | | | | | and RELENG_5 and | | | | | needs final | | | | | testing. | |-------------------+---------------+---------------+--------------------| | | | | Recent changes to | | | | | the ATA driver | | | | | trigger a bug on | | | | So/ren | sparc64 that | | ATA panics under | Needs testing | Schmidt, | causes a panic on | | sparc64 | | Scott Long | boot. This was | | | | | caused by bugs in | | | | | busdma that have | | | | | been hopefully | | | | | fixed. | |-------------------+---------------+---------------+--------------------| | | | | The ifconf() ioctl | | | | | for listing | | | | | network interfaces | | | | | performs a | | | | | copyout() while | | | | | holding the global | | | | | ifnet list mutex. | | | | | This generates a | | ifconf() sleep | Done | Brooks Davis | witness warning in | | warning | | | the event that | | | | | copyout() | | | | | generates a page | | | | | fault, and risks | | | | | more serious | | | | | problems. This | | | | | problem is | | | | | believed to be | | | | | corrected. | |-------------------+---------------+---------------+--------------------| | | | | There are reports | | | | | of applications | | | | | wedging in poll() | | | | | and select() while | | | | | running the | | | | | network stack | | | | | without the Giant | | poll()/select() | | | lock. A recent | | application wedge | | | sleepq change | | reports with | Done | Robert Watson | appears to have | | debug.mpsafenet=1 | | | caused some of the | | | | | observed problems | | | | | to go away (others | | | | | are difficult to | | | | | test for due to | | | | | recent SMP | | | | | instability). This | | | | | problem appears to | | | | | be corrected. | |-------------------+---------------+---------------+--------------------| | | | | There have been | | | | | several reports of | | | | | if_em cards | | if_em wedging | | | "wedging" under | | under high pps | Done | Max Laier | high | | | | | packets-per-second | | | | | load. This problem | | | | | appears to have | | | | | been corrected. | |-------------------+---------------+---------------+--------------------| | | | | A recent | | | | | regression in the | | | | | USB code is | | Panic on USB | | Warner Losh, | causing panics | | detach | Needs testing | Scott Long | when a USB device | | | | | detaches, | | | | | especially USB | | | | | hubs. A fix is in | | | | | RELENG_5 now. | |-------------------+---------------+---------------+--------------------| | | | | There are reports | | | | | that racoon is | | | | | unable to complete | | | | | IKE negotiation | | | | | due to a send to | | | | | the pfkey socket | | | | | returning ENOBUFS. | | KAME IPSEC | | Robert | This appears to be | | "ENOBUFS" problem | Done | Watson, Sam | a result of an | | with racoon and | | Leffler | incorrect | | mbuma | | | assumption about | | | | | mbuf data size due | | | | | to a change | | | | | resulting from | | | | | mbuma. This | | | | | problem appears to | | | | | have been | | | | | corrected. | |-------------------+---------------+---------------+--------------------| | | | | BIND9 is now in | | | | | RELENG_5 and HEAD. | | | | Doug Barton, | Testing is needed | | BIND9 import into | | Dag-Erling | of basic | | 5-CURRENT | Done | Smorgrav, Tom | functionality, | | | | Rhodes | migration from | | | | | 8.x, and 3rd party | | | | | packages in the | | | | | ports tree. | |-------------------+---------------+---------------+--------------------| | | | | Synaptics updates | | | | | to the psm(4) | | | | | driver have | | | | | resulted in poor | | | | | interactivity for | | | | | taps and button | | Synaptics | Needs testing | Philip Paeps | press events for | | touchpad problems | | | some users. | | | | | Support is now | | | | | disabled by | | | | | default but work | | | | | will procede to | | | | | fix the underlying | | | | | problems. | |-------------------+---------------+---------------+--------------------| | | | | Significant work | | | | | has happened in | | Scheduler-related | | Scott Long, | the scheduler to | | hangs involving | Needs testing | Julian | fix stability | | threads | | Elischer | problems. More | | | | | testing for UP and | | | | | SMP under heavily | | | | | load is needed. | |-------------------+---------------+---------------+--------------------| | | | | Jun Kuriyama has | | | | | reported problems | | | | | with NFS over IPv6 | | | | | not functioning | | | | | correctly as of | | | | | the improved NFS | | | | | support for | | | | | disconnection | | | | | changes. Doug | | | | | White has tracked | | NFS over IPv6 | | | down the source of | | problems | Done | Doug White | the problem | | | | | (EMSGSIZE being | | | | | returned by IPv6 | | | | | UDP send routine | | | | | due to | | | | | fragmentation), | | | | | and is currently | | | | | exploring possible | | | | | fixes. This | | | | | problem appears to | | | | | have been | | | | | corrected. | |-------------------+---------------+---------------+--------------------| | | | | There have been | | | | | reports of | | | | | occasional | | | | | corruption of | | | | | socket buffers. | | | | | This may have been | | Reports of socket | | | the result of | | buffer corruption | Done | Robert Watson | missing socket | | in tcp_output() | | | buffer locking in | | | | | tcp_output(), | | | | | which has now been | | | | | corrected in 6.x | | | | | and 5.x; this | | | | | problem is | | | | | believed to be | | | | | fixed. | |-------------------+---------------+---------------+--------------------| | | | | There have been | | | | | reports of system | | | | | hangs while using | | | | | ISDN with the i4b | | | | | ISDN framework on | | | | | SMP systems. These | | | | | likely result from | | | | | insufficient | | | | | synchronization in | | | | | the i4b | | | | | implementation | | | | | when runnning | | Reports of hangs | | | without the Giant | | using i4b | Done | Robert Watson | lock over the | | (isdn4bsd) | | | network stack. The | | | | | workaround until | | | | | this is fixed is | | | | | to re-assert the | | | | | Giant lock over | | | | | the stack when i4b | | | | | is compiled into | | | | | the kernel; this | | | | | has been committed | | | | | to 6.x and and | | | | | 5.x. This problem | | | | | appears to have | | | | | been corrected. | |-------------------+---------------+---------------+--------------------| | | | | There have been | | | | | reports that | | | | | multicast socket | | | | | options on raw | | | | | sockets no longer | | | | | work properly with | | | | | daemons changing | | | | | privilege or | | | | | setuid binaries. | | Problems with | | Robert | These symptoms | | multicast and | Done | Watson, | have been tracked | | setuid | | Christian | down to bugs | | binaries/daemons | | Peron | relating to | | | | | permitting limited | | | | | use of raw sockets | | | | | in jail(). A patch | | | | | correcting these | | | | | problems has been | | | | | merged to 6.x and | | | | | 5.x. This problem | | | | | appears to have | | | | | been corrected. | |-------------------+---------------+---------------+--------------------| | | | | There have been | | | | | reports of a | | | | | so_count invariant | | | | | violation in | | | | | sofree(), which | | | | | may relate to race | | Reports of | | Robert | conditions in | | sodealloc() panic | Done | Watson, Brian | sofree() against | | under heavy load | | Feldman | accept(), which | | | | | were recently | | | | | corrected in 6.x, | | | | | and has been | | | | | merged to 5.x. | | | | | This problem | | | | | appears to have | | | | | been corrected. | |-------------------+---------------+---------------+--------------------| | | | | Apple's Darwin | | | | | operating system | | | | | has fairly | | | | | extensive | | Merge of Darwin | | | improvements to | | msdosfs, other | Done | -- | msdosfs and other | | fixes | | | kernel services; | | | | | these fixes must | | | | | be reviewed and | | | | | merged to the | | | | | FreeBSD tree. | |-------------------+---------------+---------------+--------------------| | | | | There have been | | | | | reports that if_de | | | | | ethernet cds | | | | | behave poorly when | | | | | running with | | | | | debug.mpsafenet=1, | | | | | even though the | | | | | driver is marked | | Reports of poor | | | to run all | | performance of | | Robert | portions with the | | the if_de driver | Done | Watson, | Giant lock. This | | (de ethernet | | John-Mark | suggests a race | | interfaces) | | Gurney | condition specific | | | | | to this drive, | | | | | which is currently | | | | | being debugged. A | | | | | patch has been | | | | | committed to the | | | | | 6.x and 5.x | | | | | branches, and | | | | | appears to correct | | | | | the problem. | |-------------------+---------------+---------------+--------------------| | | | | Attaching GDB to a | | | | | threaded process | | | | | will leave the | | | | | process in an | | | | | unkillable state. | | | | | Rebooting the | | | | | machine is the | | Threaded | | | only way to | | application get | | | recover from this. | | stuck in an | | | This is easily | | unkillable state | Done | David Xu | triggered when a | | when touched by | | | KDE app crashes | | GDB | | | and KDE | | | | | automatically | | | | | attaches GDB to it | | | | | to extract a stack | | | | | trace. A candidate | | | | | fix is in | | | | | 6-CURRENT. More | | | | | testing and review | | | | | is needed. | |-------------------+---------------+---------------+--------------------| | | | | Truss appears to | | | | | have another | | | | | problem. It is | | | | | repeatable by | | | | | running "truss -f | | More truss | | Alfred | fsck -p /", | | problems | Done | Perlstein | suspending it with | | | | | ^Z, and then | | | | | killing truss. It | | | | | will leave behind | | | | | the fsck processes | | | | | which will be | | | | | unkillable. | |-------------------+---------------+---------------+--------------------| | | | | There have been | | | | | reports that, | | | | | under extremely | | | | | high load, the | | | | | tcp_output() | | | | | routine may appear | | | | | to run for | | Reports of | | George V. | extended periods, | | TCP-related | | Neville-Neil, | resulting in the | | instability under | Needs testing | Robert | appearance of a | | extremely high | | Watson, | hang for an | | load; possibly | | Scott Long | extended period | | related to SACK | | | (up to 30 | | | | | minutes), followed | | | | | by recovery.
