Show stopper defects for 5.3-RELEASE
+------------------------------------------------------------------------+
| Issue | Status | Responsible | Description |
|----------------+-------------+---------------+-------------------------|
| | | | More problems have been |
| | | Bruce M. | reported with the if_em |
| if_em wedge | In progress | Simpson | driver. These appear to |
| | | | also be related to the |
| | | | ALTQ code. |
|----------------+-------------+---------------+-------------------------|
| | | | 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 |
| Reports of | | | 6.x, and has been |
| sodealloc() | | Robert | merged to 5.x. It has |
| panic under | In progress | Watson, Brian | not yet been confirmed |
| heavy load | | Feldman | 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 |
| | | | engineering team in |
| | | | testing. |
|----------------+-------------+---------------+-------------------------|
| | | | There have been reports |
| | | | that if_de ethernet cds |
| | | | behave poorly when |
| | | | running with |
| | | | debug.mpsafenet=1, even |
| Reports of | | | though the driver is |
| poor | | | marked to run all |
| performance of | | Robert | portions with the Giant |
| the if_de | In progress | Watson, | lock. This suggests a |
| driver (de | | John-Mark | race condition specific |
| ethernet | | Gurney | to this drive, which is |
| interfaces) | | | currently being |
| | | | debugged. A patch has |
| | | | been posted that |
| | | | appears to correct the |
| | | | problem, and will be |
| | | | merged to 6.x and 5.x |
| | | | shortly. |
|----------------+-------------+---------------+-------------------------|
| | | | There have been reports |
| | | | that specific gigabit |
| | | | ethernet cards |
| | | | supported by the if_re |
| Reports of | | | driver are experiencing |
| poor | | | poor performance; a |
| performance | | John-Mark | patch has been posted |
| with the if_re | In progress | Gurney | that corrects timer and |
| driver (re | | | interrupt problems with |
| ethernet | | | the driver, and is |
| interfaces) | | | believed to correct the |
| | | | performace problems. |
| | | | The patch will be |
| | | | merged to 6.x and 5.x |
| | | | shortly. |

Desired features for 5.3-RELEASE
+------------------------------------------------------------------------+
| Issue | Status | Responsible | Description |
|------------------+-------------+----------------+----------------------|
| | | | Entropy harvesting |
| | | | in the interrupt and |
| | | | incoming packet |
| | | | paths currently |
| | | | involves a large |
| | | | number of mutex |
| | | | operations. In order |
| | | | to improve |
| | | | performance, it is |
| Entropy | | Robert Watson, | desirable to reduce |
| harvesting | In progress | Mark Murray | the number of mutex |
| optimizations | | | operations |
| | | | substantially. |
| | | | Improvements in the |
| | | | harvesting locking |
| | | | scheme have been |
| | | | merged to 6.x, but |
| | | | are considered too |
| | | | risky at this stage |
| | | | to be merged to 5.x |
| | | | until after 5.3. |
|------------------+-------------+----------------+----------------------|
| | | | 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. |
|------------------+-------------+----------------+----------------------|
| | | | 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. Problem |
| | | | reported by Kris |
| syscons not | | | Kennaway. Debugging |
| working on | Not done | -- | difficult due to |
| Sparc64 Ultra-30 | | | lack of this |
| | | | particular |
| | | | configuration among |
| | | | developers and |
| | | | problem isn't |
| | | | present on similar |
| | | | hardware (e.g. no |

Testing focuses for 5.3-RELEASE
+------------------------------------------------------------------------+
| Issue | Status | Responsible | Description |
|--------------------+---------------+--------------+--------------------|
| | | | KSE has matured to |
| | | | the point of being |
| | | | more stable and |
| | | | POSIX-compliant |
| | | | than the |
| | | | traditional |
| | | | libc_r. 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. |

| | | | 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 |

| | | | There have been |
| | | | reports of system |
| | | | hangs while using |
| | | | ISDN with the i4b |
| | | | ISDN framework on |
| | | | SMP systems. These |
| | | | likely result from |
| | | | insufficient |

| | | | 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 |
