if the path was given in a user buffer, return the new path in
a user buffer.
if the path was given in a kernel buffer, allocate a new kernel buffer
to return the new path; the caller is responsible for freeing the buffer
if we fail always set the new path to NULL.
This usage broke when I adde the /../ shortcut. Noted by cgd.
* add arguments describing the vnode and ecoff header of the executable
being set up to the [onz]magic setup functions.
* export the stack setup function and the [onz]magic setup functions.
* call the MD ecoff hook _before_ the [onz]magic and stack setup
functions, and bail out early if the MD hook sets up vmcmds.
+ Make installation/diskimage installation/netboot in ${RELEASEDIR}
+ snap_md_post depends on the diskimage, the diskimage tar file and
the install kernel, and installs these into the right places in
${RELEASEDIR}.
port-specific Makefiles can add to.
+ Separate snap_md into snap_md_pre and snap_md_post that are depended
on before and after snap_kern.
+ Build all kernels listing in ${BUILD_KERNELS}, but don't put them in
${RELEASEDIR}.
- Initialize mbpool and mclpool with msize and mclbytes, respectively,
so that those values may be patched and have an actual affect on the
next system reboot.
- Set low water marks on mbpool (default: 16) and mclpool (default: 8).
This should be of great help for diskless systems, which need to allocate
mbufs in order to clean dirty pages; the low water marks increase the
chances of this being possible to do in memory starvation situations.
- Add support for getting/setting some mbuf-related parameters via sysctl.
* msize and mclsize (read-only)
* nmbclusters (read-only unless the platform has direct-mapped pool pages,
in which case the value can be increased).
* mblowat and mcllowat (read/write)
exposure of TC device any more. Correct comments which are no longer
feasible. Reorder declarations and definitions. Introduce 'clkread'
pointer to pull up model dependent high resolution timer value. Have
prom_systype() call.
- Place routines for model dependent high resolution timer.
- Program IOASIC registers inside os_init() call and nuke ioasic_init().
buffer size of zero if stdout has a block size of 0.
The command `rsh <host> cat <files>' gives no output and no error.
- Allocate a minimum of BUFSIZ bytes for buffer.
- Use a static buffer if either `fstat' or `malloc' fails.
- Do the allocation once since stdout will not change block size.
