OpenBSD src changes summary for 2012-04-05
== sbin ============================================================== 01/04 ==
~ control.c ~ iked.h
> rate-limit accepting of new connections while we are experiencing
> fd exhaustion.
> ok mikeb (deraadt@)
== share ============================================================= 02/04 ==
> Mention clang module. (sthen@)
== sys =============================================================== 03/04 ==
~ hpc.c ~ hpcvar.h
> DMA descriptors only need to be aligned on 8-byte boundaries, and the
> layout is enough to enforce this. Don't request DMA page boundary alignment
> when allocating them. (miod@)
> Add an explicit bus_space_barrier() function for revision 3 hpc, which has
> PIO write buffer. (miod@)
> Lower ZS_DELAY() back to what it was, but issue a bus_space_barrier() after
> every register write. Hinted by IRIX' <sys/z8530.h>.
> While there, flip the CTS, DCD, RTS and DTR bits in registers #0 and #5.
> Aforementioned header says they are inverted due to a hardware bug.
> Tested on IP20, IP22 and IP24. (miod@)
> In the neverending tradition of never making things simple, SGI used 1940
> the timebase on Indigo 2, but 1970 on Indy (verified with the `date'
> at the PROM prompt and checking what values ended up in the DS1286).
> Indy will no longer be 30 years in the future from an IRIX point of view.
> Bail out of bus_dmamap_sync() earlier in the non-PREWRITE cases on
> kernels. No need to walk the whole dma map doing nothing.
> No functional change. (miod@)
> add some devices found on a r720
> ok dlg@ (jsg@)
~ pcidevs.h ~ pcidevs_data.h
> regen (jsg@)
~ denode.h ~ msdosfs_fat.c
> As it was made evident by Olaf 'Rhialto' Seibert in the NetBSD PR 34583,
> caching the last cluster in the file before extending it considerably
> speeds up further lookups. As a consequence this keeps write speed from
> gradually decreasing and provides a measurable (up to 2x) performance
> increase. Prompted by the diff from Alexander Polakov, ok miod, krw.
== usr.sbin ========================================================== 04/04 ==
> Rate-limit accepting of new connections while we are experiencing
> fd exhaustion.
> ok deraadt mikeb (camield@)
> Mention the -u flag to tell nginx not to chroot.
> Help with wording from jmc@, thanks! (sthen@)
