bf26b4d9e4
in devsw_name2blk(), as we use strncmp(), make sure the next character
...
in the device is either nul or a digit. this avoids "raid0" being
matched as the "ra" device (and thus failing to find anything at all
causing my raid0 root to fail) on my vax.

Add extensible malloc types, adapted from FreeBSD. This turns
...
malloc types into a structure, a pointer to which is passed around,
instead of an int constant. Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.

Two small changes to the ELF exec code:
...
(1) ELFNAME(load_file)() now takes a pointer to the entry point
offset, instead of taking a pointer to the entry point itself. This
allows proper adjustment of the ultimate entry point at a higher level
if the object containing the entry point is moved before the exec is
finished.
(2) Introduce VMCMD_FIXED, which means the address at which a given
vmcmd describes a mapping is fixed (ie, should not be moved). Don't
set this for entries pertaining to ld.so.
Also some minor comment/whitespace tweaks.

Fix _lwp_wakeup() so that it stands a chance of working (although it
...
turns out to be insufficent for signal-level interruption of system
calls. guess we need _lwp_kill(), ugh).
2003-01-29 23:27:54 +00:00

Fix proc_representative_lwp(); a closing brace was in the wrong place,

which means it would return the first non-dead LWP.

There's a locking order issue with the scheduler and the callwheel locks
...
as ltsleep() may call callout_reset() with the scheduler lock held.
So, prevent interrupts that may take the scheduler lock while holding
the callwheel lock.
2003-01-27 22:38:24 +00:00
01ca174f62
Call exit_lwps() from exit1() if there is more than one LWP (as
...
recorded by p_nlwps) *or* if the process was a SA process. Since
cached SA LWPs aren't counted in p_nlwps, it was possible for
them to not be cleaned up and remain on the alllwp list, pointing to a
dead proc.
2003-01-27 20:30:32 +00:00
a3ff3a3038
Bump daddr_t to 64 bits. Replace it with int32_t in all places where
...
it was used on-disk, so that on-disk formats remain the same.
Remove ufs_daddr_t and ufs_lbn_t for the time being.
