mbuf fields, and it seems it doesn't allocate mbuf clusters for large
packets. So revert to using MCLGET() if needed and memcpy to get the
data in the mbuf.
Should fix panic in m_makewritable() reported by Mike M. Volokhov
and Andreas Wrede on port-xen, patch tested by Andreas Wrede.
1) Add the NVRAM device. This device allows us to speak with the nvram on
prep-based machines and read/write to it. Also add a simple IOCTL
interface for speaking with the nvram from userland. This hasn't been
tested yet, but eventually I plan to support it with the sparc eeprom
command.
2) Change the root device detection to use the nvram device to attempt to
guess the boot device. Most machines should now correctly guess thier
boot device, though I expect a few devices to still not work quite right yet.
3) change the default IRQ to level rather than edge in the pnpbus if the
flags are invalid or empty. (based on output from a PowerStack E1)
4) correctly handle older machines in pnpbus that have FixedIOPorts
rather than variable ones.
Still have much to do.
like this, where a user may well want to install one of these but not the
other.
To allow syspkg to be used for its intended purpose here, carefully split
out ipfilter and pf from the main {base,comp,man,misc}-net{,util}-* packages
(something which was partially done for ipf, but not done for pf in the
past).
This way, a user can pkg_delete *-{ipf,pf}-*, and not have utilities,
libraries, man pages, examples, or default /etc files for the packet filter
they don't like.
To fix lingering problems with the LV/ULV Pentium Ms that run with a 400 MHz
FSB (738, et al), change ENTRY() yet again to directly include the FSB
multiplier - CPUID isn't enough to determine what it should be.
While I'm at it, add more values for the 750, and fix values for the 730
and 770 to jibe with what the 'prescribed' values (via ACPI) are.
Fixes PR/33080 and PR/33081.
any purpose (done by a macro, so we don't save any cycles for now)
-kill vm_fault_t; it is not needed for real faults, and for simulated
faults (wiring) it can be replaced by UVM internal flags
-remove <uvm/uvm_fault.h> from uvm_extern.h again
to vslock(9). This prevents a local DOS.
(The checks against system and user limits for wired
memory should be centralized in UVM; for now prefer a less
invasive fix which can be pulled pulled up into releases.)
used.
Remove defect in size allocation for coda_readlink to avoid having
venus write outside malloced space by including pathname space before
allocation.
Add asserts that cred structure is non-NULL and non-FSCRED.
Check lwp against NULL before dereferencing it.
Assert that output pointer is non-NULL on a few venus returns. This "can't
happen" but has been seen in crash dumps.
With these changes, the following work on a 345 MB coda volume.
(Before, a single invocation of tar or pax on this volume would
crash.)
$ for i in $(seq 1 10); do find . -type f -print0 |xargs -0 md5 > MD5.$i & done
Two copies of
$ for i in $(seq 1 10); do pax -w /coda/[redacted] >/dev/null & done
