     | | | |PREEMPTION appears to |
     | | | |increase the chances of |
     | | | |triggering a race |
     | | | |condition in the thread |
     |PREEMPTION-related | |Scott Long, |context management and |
     |hangs involving |In progress|Julian |scheduling code. Patches |
     |threads | |Elischer |to mitigate the problem |
     | | | |have been developed, with|
     | | | |on-going work to come up |
     | | | |with the correct solution|
     | | | |prior to 5.3. |

     | | | |Jun Kuriyama has reported|
     | | | |problems with NFS over |
     | | | |IPv6 not functioning |
     | | | |correctly as of the |
     | | | |improved NFS support for |
     | | | |disconnection changes. |
     |NFS over IPv6 |In progress|Doug White |Doug White has tracked |
     |problems | | |down the source of the |
     | | | |problem (EMSGSIZE being |
     | | | |returned by IPv6 UDP send|
     | | | |routine due to |
     | | | |fragmentation), and is |
     | | | |currently exploring |
     | | | |possible fixes. |

     | | | |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 |
     |poll()/select() | | |(others are difficult to |
     |application wedge |In progress|Robert Watson|test for due to recent |
     |reports with | | |SMP instability). A fix |
     |debug.mpsafenet=1 | | |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. |

    Required features for 5.3-RELEASE

     | | | | With improved support |
     | | | | for threading |
     | | | | primitives, support |

     | GDB thread | | David Xu, | ease debugging of |
     | support | In progress | Marcel | threaded |

     | | | | Ideally, this support |

     | | | | threading models. |
     |-----------------+-------------+----------------+-----------------------|

    Desired features for 5.3-RELEASE

     +------------------------------------------------------------------------+
     | Issue | Status | Responsible | Description |
     |------------------+-------------+----------------+----------------------|
     | | | | 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. |

    Testing focuses for 5.3-RELEASE

     +------------------------------------------------------------------------+
     | Issue | Status | Responsible | Description |
     |-------------------+---------------+--------------+---------------------|
     | | | | SCHED_ULE provides |
     | | | | better |
     | | | | interactivity, |
     | | | | higher performance, |
     | SCHED_ULE as the | Needs testing | Jeff | and the ability to |
     | default scheduler | | Roberson | support pinning and |
     | | | | affinity. Basic HTT |
     | | | | scheduling policies |
     | | | | should be in place |
     | | | | for 5.3 also. |
     |-------------------+---------------+--------------+---------------------|
     | | | | KSE has matured to |
     | | | | the point of being |
     | | | | more stable and |
     | | | | POSIX-compliant |
     | | | | than the |
     | | | | traditional libc_r. |
     | | | | All Tier-1 |
     | | | | platforms MUST have |
     | KSE as the | | David Xu, | stable KSE support |
     | default threads | Needs testing | Daniel | for 5.3 in order to |
     | library | | Eischen | support a |
     | | | | 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-architecture |
     | Per-platform | | Doug Rabson, | changes must be |
     | Thread-Local | Needs testing | Marcel | made. Currently |
     | Storage | | Moolenaar | 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 has |
     | SMP instability | | Doug White, | 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 | Needs testing | Robert | number of device |
     | locking without | | 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 |
     | ATA panics under | | So/ren | sparc64 that causes |
     | sparc64 | Needs testing | Schmidt, | a panic on boot. |
     | | | Scott Long | This was caused by |
     | | | | bugs in busdma that |
     | | | | have been hopefully |
     | | | | fixed. |
