Show stopper defects for 5.3-RELEASE +------------------------------------------------------------------------+ | Issue | Status | Responsible | Description | |---------------+-------------+---------------+--------------------------| | | | | ether_input() calls | | | | | random_harvest() on the | | | | | mbuf after it has been | | | | | handed off to | | | | | ether_demux(), at which | | | | | point it may have been | | ether_input() | | | free()'d back to the | | may harvest | In progress | Mark Murray, | mbuf allocator. It also | | entropy from | | Robert Watson | passes in a pointer to | | free()'d mbuf | | | the mbuf itself, rather | | | | | than ethernet frame | | | | | header. Passing of a | | | | | potentially free'd mbuf | | | | | has been corrected in | | | | | 6.x, but not yet merged | | | | | to 5.x. | +------------------------------------------------------------------------+ Required features for 5.3-RELEASE +------------------------------------------------------------------------+ | Issue | Status | Responsible | Description | |--------------------+-------------+---------------+---------------------| | | | | With improved | | | | | support for | | | | | threading | | | | | primitives, support | | | | | is now required to | | | | David Xu, | ease debugging of | | GDB thread support | In progress | Marcel | threaded | | | | Moolenaar | applications. | | | | | Ideally, this | | | | | support will work | | | | | for both libthr and | | | | | libkse threading | | | | | models. | |--------------------+-------------+---------------+---------------------| | | | | Entropy harvesting | | | | | in the interrupt | | | | | and incoming packet | | | | | paths currently | | | | | involves a large | | | | | number of mutex | | | | | operations. In | | | | | order to improve | | | | | performance, it is | | | | Robert | desirable to reduce | | Entropy harvesting | In progress | Watson, | the number of mutex | | optimizations | | Mark Murray | operations | | | | | substantially. Work | | | | | is in progress to | | | | | improve the | | | | | harvesting code | | | | | along these lines, | | | | | but has not yet | | | | | been properly | | | | | measured, and | | | | | therefore not yet | | | | | merged to CVS. | |--------------------+-------------+---------------+---------------------| | | | | There have been | | | | | reports of | | | | | occasional | | | | | corruption of | | | | | socket buffers | | | | | and/or spinning in | | Reports of | | | tcp_output(). This | | tcp_output() | In progress | Robert Watson | may have been the | | spinning; socket | | | result of missing | | buffer corruption | | | socket buffer | | | | | locking in | | | | | tcp_output(), which | | | | | has now been | | | | | corrected in 6.x, | | | | | and will be merged | | | | | to 5.x shortly. | |--------------------+-------------+---------------+---------------------| | | | | There have been | | | | | reports of a | | | | | so_count invariant | | | | | violation in | | | | | sofree(), which may | | | | | relate to race | | | | | conditions in | | | | | sofree() against | | | | | accept(), which | | | | | were recently | | | | | corrected in 6.x, | | | | | with an intent to | | Reports of | | Robert | merge to 5.x | | sodealloc() panic | In progress | Watson, Brian | shortly. It has not | | under heavy load | | Feldman | yet been confirmed | | | | | that the race fix | | | | | corrects the | | | | | symptom, as it | | | | | takes several days | | | | | to reproduce in | | | | | high load | | | | | environments, and | | | | | has not yet been | | | | | reproduced by the | | | | | FreeBSD release | | | | | engineerig team in | | | | | testing. | |--------------------+-------------+---------------+---------------------| | | | | There have been | | | | | reports that | | | | | multicast socket | | | | | options on raw | | | | | sockets no longer | | | | | work properly with | | | | | daemons changing | | | | | privilege or setuid | | | | | binaries. These | | Problems with | | Robert | symptoms have been | | multicast and | In progress | Watson, | tracked down to | | setuid | | Christian | bugs relating to | | binaries/daemons | | Peron | permitting limited | | | | | use of raw sockets | | | | | in jail(). A patch | | | | | correcting these | | | | | problems has been | | | | | posted for review, | | | | | but not yet been | | | | | merged to 6.x or | | | | | 5.x. It will be | | | | | merged shortly. | |--------------------+-------------+---------------+---------------------| | | | | 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 | | Reports of hangs | | | runnning without | | using i4b | In progress | Robert Watson | the Giant lock over | | (isdn4bsd) | | | the 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 will be | | | | | merged to 5.x | | | | | shortly. | +------------------------------------------------------------------------+ Desired features for 5.3-RELEASE +------------------------------------------------------------------------+ | Issue | Status | Responsible | Description | |------------------+-------------+----------------+----------------------| | | | | 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. | |------------------+-------------+----------------+----------------------| | | | | Apple's Darwin | | | | | operating system has | | | | | fairly extensive | | Merge of Darwin | | | improvements to | | msdosfs, other | Not done | -- | msdosfs and other | | fixes | | | kernel services; | | | | | these fixes must be | | | | | reviewed and merged | | | | | to the FreeBSD tree. | |------------------+-------------+----------------+----------------------| | | | | 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. | |------------------+-------------+----------------+----------------------| | | | | Truss appears to | | | | | have another | | | | | problem. It is | | | | | repeatable by | | | | | running "truss -f | | More truss | Not done | -- | fsck -p /", | | problems | | | suspending it with | | | | | ^Z, and then killing | | | | | truss. It will leave | | | | | behind the fsck | | | | | processes which will | | | | | be unkillable. | |------------------+-------------+----------------+----------------------| | | | | Many systems | | | | | supporting POSIX.1e | | | | | ACLs permit a minor | | | | | violation to that | | | | | specification, in | | | | | which the ACL_MASK | | ACL_MASK | | | entry overrides the | | override of | Not done | Robert Watson | umask, rather than | | umask support in | | | being intersected | | UFS | | | with it. The | | | | | resulting semantics | | | | | can be useful in | | | | | group-oriented | | | | | environments, and as | | | | | such would be very | | | | | helpful on FreeBSD. | |------------------+-------------+----------------+----------------------| | | | | The LOR reported in | | | | | PR kern/55175 needs | | filedesc LOR | Not done | -- | to be fixed. | | | | | Filedesc locking | | | | | needs to be heavily | | | | | reviewed in general. | |------------------+-------------+----------------+----------------------| | | | | Currently, MAC | | | | | protections are | | | | | enforced only on | | | | | locally originated | | | | | file system | | | | | operations (VOPs), | | | | | and not on RPCs | | | | | generated via the | | | | | NFS server. | | MAC support for | | | Improvements in NFS | | NFS Server | Not done | Robert Watson | server credential | | | | | handling are | | | | | required to correct | | | | | this problem, as | | | | | well as the | | | | | introduction of new | | | | | entry points to | | | | | properly label NFS | | | | | credentials and | | | | | perform enforcement | | | | | properly. | |------------------+-------------+----------------+----------------------| | | | | All PCI drivers must | | | | | use busdma for DMA; | | | | | no use of vtophys() | | busdma in all | In progress | -- | will be permitted | | PCI drivers | | | for any recent | | | | | device driver. ISA | | | | | drivers may be | | | | | exempt. | |------------------+-------------+----------------+----------------------| | | | | 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 | | | | David Xu, | support for 5.3 in | | KSE as the default | Needs testing | Daniel | order to support a | | threads 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 | | David | to support new | | for all platforms | Needs testing | 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 | | | | | reportged a failed | | | | | locking assertion | | | | | with IPv6 TCP | | in6_pcbnotify() | Needs testing | Robert | notifications. A | | panic with TCP | | Watson | patch has been | | | | | committed to the | | | | | CVS HEAD and | | | | | RELENG_5 and needs | | | | | further testing. | |--------------------+---------------+--------------+--------------------| | | | | 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 | | Robert | number of device | | locking without | Needs testing | Watson | drivers and less | | Giant | | | mainstream network | | | | | subsystems are | | | | | currently not | | | | | MPSAFE. By | | | | | 5.3-RELEASE, it is | | | | | necessary to have | | | | | the vast majority | | | | | of network code | | | | | running without | | | | | Giant, including | | | | | sockets, | | | | | permitting | | | | | complete | | | | | local<->remote | | | | | delivery without | | | | | grabbing Giant. | |--------------------+---------------+--------------+--------------------| | | | | 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 | | | witness warning in | | warning | Needs testing | Brooks Davis | the event that | | | | | copyout() | | | | | generates a page | | | | | fault, and risks | | | | | more serious | | | | | problems. A patch | | | | | has been committed | | | | | to HEAD and | | | | | RELENG_5, but | | | | | requires testing. | |--------------------+---------------+--------------+--------------------| | | | | There are reports | | | | | of applications | | | | | wedging in poll() | | | | | and select() while | | | | | running the | | | | | network stack | | | | | without the Giant | | | | | lock. A recent | | | | | sleepq change | | | | | appears to have | | | | | caused some of the | | | | | observed problems | | | | | to go away (others | | | | | are difficult to | | poll()/select() | | | test for due to | | application wedge | Needs testing | Robert | recent SMP | | reports with | | Watson | instability). A | | debug.mpsafenet=1 | | | fix has been | | | | | committed to CVS | | | | | HEAD and merged to | | | | | RELENG_5 and | | | | | appears to resolve | | | | | problems with | | | | | poll(); we are | | | | | waiting for | | | | | feedback that it | | | | | has corrected the | | | | | reported problems | | | | | with select() also | | | | | before moving this | | | | | to "testing" | | | | | status. | |--------------------+---------------+--------------+--------------------| | | | | There have been | | | | | several reports of | | | | | if_em cards | | if_em wedging | Needs testing | Max Laier | "wedging" under | | under high pps | | | high | | | | | packets-per-second | | | | | load. A fix is in | | | | | RELENG_5 now. | |--------------------+---------------+--------------+--------------------| | | | | 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 | | KAME IPSEC | | | returning ENOBUFS. | | "ENOBUFS" problem | | Robert | This appears to be | | with racoon and | Needs testing | Watson | a result of an | | mbuma | | | incorrect | | | | | assumption about | | | | | mbuf data size due | | | | | to a change | | | | | resulting from | | | | | mbuma. A fix for | | | | | this is in | | | | | RELENG_5 now. | |--------------------+---------------+--------------+--------------------| | | | | BIND9 is now in | | | | | RELENG_5 and HEAD. | | | | Doug Barton, | Testing is needed | | BIND9 import into | | Dag-Erling | of basic | | 5-CURRENT | Needs testing | Smorgrav, | functionality, | | | | Tom 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 touchpad | Needs testing | Philip Paeps | press events for | | 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.
