file name data and the entry starts with \0\0. Apparently this happens
occasionally, don't know if it's mtools (probably), MS Windows or
NetBSD msdosfs fault. When this happens, NetBSD msdosfs was not
able to open the file, where neither mtools nor MS Windows had any
problem with it. So, it's appropriate to add this fix in any case.
of tv's previous code, which skips uname or gname parsing if -W is enabled.
- rename "lineno" to "mtree_lineno", to reduce possibility of name
clashes in code that yanks in spec.c & misc.c (unlikely, but you never know)
we need later in the code. This fixes a fatal kernel fault in
pmap_modified_emulation if a user application tries to access a kernel
address that is section-mapped.
Add a diagnostic that detects attempts to call pmap_kenter_pa with a
va that is section-mapped.
alias expansion inside the switch as appropriate. This is achieved by a
flag noalias which is turned on and off in as we parse. In the following
example [1] and [0] indicate the value of noalias.
[0] case <expr> in
[1] <lit> ) [0] <expr> ;;
[1] <lit> ) [0] <expr> ;;
...
[1] esac [0]
FreeBSD does:
[0] case <expr> in [1]
<lit> ) <expr> ;;
<lit> ) <expr> ;;
...
esac [0]
This handles the following shell script:
alias a=ls
case $1 in
a) echo a;
a;;
f) echo f;;
*) echo default;;
esac
- Set MARK_START to where we expect to be loading the kernel (0xf0100000).
- The ARM OpenFirmare bindings document describes how the client
program is loaded: OFW allocates and maps 6MB of memory at load-base
(0xf0000000), loads the client program, and then unmaps the memory from
the end of the client program to the end of the allocated region. Then
transfers control to the client program. We must emulate this behavior
to load the kernel: allocate 5MB at 0xf0100000 (where we expect to load
the kernel), load the kernel, then unmap the area after the kernel.
We can now load DHCP and load the kernel via NFS before getting the
dreaded Data Abort.
Re-write t_agetstr() so that it does not use realloc so userland
programs don't break. We now use an internal buffer to keep track
of the memory we allocate. This changes the api of t_agetstr() to
take 2 fewer arguments, but there are not many programs that use it.
Please note that this does not change binary compatibility with the
previous t_agetstr() since the usage was:
char *area, *p;
*area = NULL;
t_agetstr(ti, "ic", &area, &p);
...
free(area);
Since we don't touch the arguments and free(NULL) is a no-op, nothing
breaks.
Since we don't break binary compatibility there is no reason to bump
the library's major number, but since we change t_agetstr() I'll bump
the minor number for good measure.
descriptive comments. The guts of hostprog, lib, and prog are mostly
unchanged; this will be done in another pass.
Make several things work properly with UNPRIVILEGED set, and make the
install-time "cmp" logic work for MANZ. Also reimplement INCS{DIR,NAME}_foo
(requested by wiz) in a backwards compatible way.

* Set stuff mostly in the environment, not on make(1)'s command line.
This is needed for MACHINE and MACHINE_ARCH (noted by bjh21), and keeps
the mk.conf-overriding-env behavior (suggested by several people).
* Use MAKEFLAGS to make the wrapper script more readable.
* When prepping objdir in tools for the default TOOLDIR value, just make
that objdir; leave the recursive "make obj" for later.
breaks too many situations, including MAKEOBJDIR with a :C,foo,bar,
transform in many cases. It's ambiguous and unreliable, as the comment
above that code always indicated. In order to have reliable objdirs, they
need to work the same way Every Time.
(Note that taking this out is not a performance hit; we were already doing
the getcwd() call first. So the getenv("PWD") didn't increase performance.)
