Must Resolve Issues for 5.2-RELEASE
+------------------------------------------------------------------------+
| Issue | Status | Responsible | Description |
|----------------------+----------+--------------+-----------------------|
| | | | KSE M:N threading |
| | | | support is reaching |
| | | Julian | experimental yet |
| | | Elischer, | usable status on i386 |
| Production-quality | In | David Xu, | for 5.1-RELEASE. M:N |
| M:N threading | progress | Daniel | threading should be |
| | | Eischen | productionable and |
| | | | usable on all |
| | | | platforms by |
| | | | 5.2-RELEASE. |
|----------------------+----------+--------------+-----------------------|
| | | | FAST_IPSEC currently |
| | | | cannot be used |
| | | | directly with the |
| | | | KAME IPv6 |
| | | | implementation, |
| | | | requiring an |
| | | | additional level of |
| | | | IP tunnel indirection |
| | | | to protect IPv6 |
| | | | packets when using |
| | | | hardware crypto |
| FAST_IPSEC and KAME | -- | -- | acceleration. This |
| compatibility | | | 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. |
|----------------------+----------+--------------+-----------------------|
| | | | The FreeBSD KAME IPv6 |
| | | | code is now |
| | | | substantially dated |
| | | | with respect to the |
| | | | KAME vendor source. |
| KAME Synchronization | -- | -- | The FreeBSD Project |
| | | | needs to take |
| | | | initiative in driving |
| | | | the merge of new bug |
| | | | fixes, features, et |
| | | | al. |
|----------------------+----------+--------------+-----------------------|
| | | | 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 |
| truss support for | -- | -- | inherent security |
| ptrace | | | risks, it is highly |
| | | | desirable to update |
| | | | truss to operate in a |
| | | | post-procfs world. |
| | | | Dag-Erling Smorgrav |
| | | | had "work in |
| | | | progress" patches |
| | | | that will need to be |
| | | | completed and |
| | | | committed. |
|----------------------+----------+--------------+-----------------------|
| | | | Apple's Darwin |
| | | | operating system has |
| | | | fairly extensive |
| Merge of Darwin | | | improvements to |
| msdosfs, other fixes | -- | -- | msdosfs and other |
| | | | kernel services; |
| | | | these fixes must be |
| | | | reviewed and merged |
| | | | to the FreeBSD tree. |
|----------------------+----------+--------------+-----------------------|
| | | | Simple |
| | | | machine-independent |
| | | | console framework, |
| | | | based roughly on |
| | | | wscons from NetBSD, |
| Machine-independent | In | Jake | which will provide |
| console support | progress | Burkholder | better console |
| | | | support across |
| | | | architectures. Also, |
| | | | device drivers for |
| | | | peripherals relevant |
| | | | to UltraSPARC. |
|----------------------+----------+--------------+-----------------------|
| | | | Many systems |
| | | | supporting POSIX.1e |
| | | | ACLs permit a minor |
| | | | violation to that |
| | | | specification, in |
| | | | which the ACL_MASK |
| | | | entry overrides the |
| ACL_MASK override of | In | Robert | umask, rather than |
| umask support in UFS | progress | Watson | being intersected |
| | | | with it. The |
| | | | resulting semantics |
| | | | can be useful in |
| | | | group-oriented |
| | | | environments, and as |
| | | | such would be very |
| | | | helpful on FreeBSD. |
|----------------------+----------+--------------+-----------------------|
| | | | Significant parts of |
| | | | the network stack |
| | | | (especially IPv4 and |
| | | | IPv6) now have |
| | | | fine-grained locking |
| | | | of their data |
| | | | structures. However, |
| | | | it is not yet |
| | | | possible for the |
| | | | netisr threads to run |
| | | | without Giant, due to |
| Fine-grained network | In | Jeffrey Hsu, | dependencies on |
| stack locking | progress | Seigo | sockets, routing, |
| without Giant | | Tanimura | etc. A 5.2-RELEASE |
| | | | goal is to have the |
| | | | network stack running |
| | | | largely without |
| | | | Giant, which should |
| | | | substantially improve |
| | | | performance of the |
| | | | stack, as well as |
| | | | other system |
| | | | components by |
| | | | reducing contention |
| | | | on Giant. |
|----------------------+----------+--------------+-----------------------|
| | | | Move ATA comments |
| | | | into requests, so |
| | | | that they can be |
| | | | linked together, |
| | | | centralize request |
| | | | queue management |
| ATA driver | | | permitting direct DMA |
| structural | In | So/ren | of ATA commands. |
| improvements, | progress | Schmidt | These architectural |
| MPsafety | | | changes will also |
| | | | facilitate complete |
| | | | MP-safety of the ATA |
| | | | driver suite, and |
| | | | dramatically improve |
| | | | support for Promise |
| | | | RAID controllers. |
|----------------------+----------+--------------+-----------------------|
| | | | Productionable |
| | | | support for the AMD64 |
| | | | platform. Currently, |
| | | | AMD64 runs fully in |
| | | Peter Wemm, | 32-bit emulation |
| Tier-1 Support for | In | David | mode, and boots to |
| AMD64 Hammer | progress | O'Brien | single-user in 64-bit |
| | | | mode. We expect full |
| | | | production support |
| | | | for the AMD64 |
| | | | architecture in |
| | | | 5.2-RELEASE. |
|----------------------+----------+--------------+-----------------------|
| | | | To properly support |
| | | | AMD64, a compiler |
| | | | upgrade is required; |
| | | | however, the new GCC |
| | | David | 3.3 has a substantial |
| | In | O'Brien | number of new |
| GCC 3.3 upgrade | progress | Alexander | warnings that will |
| | | Kabaev | disrupt application |
| | | | support, preventing |
| | | | inclusion in |
| | | | 5.1-RELEASE. This is |
| | | | a must-have for |
| | | | 5.2-RELEASE. |
+------------------------------------------------------------------------+
Desired Features for 5.2-RELEASE
+------------------------------------------------------------------------+
| Issue | Status | Responsible | Description |
|-------------+--------+---------------+---------------------------------|
| | | | Currently, MAC protections are |
| | | | enforced only on locally |
| | | | originated file system |
| | | | operations (VOPs), and not on |
| | | | RPCs generated via the NFS |
| MAC support | | | server. Improvements in NFS |
| for NFS | -- | Robert Watson | server credential handling are |
| Server | | | 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 |
| No busdmsa | | | for DMA; no use of vtophys() |
| PCI drivers | -- | -- | will be permitted for any |
| | | | recent device driver. ISA |
| | | | drivers may be exempt. |
