arguments names on one function being swapped (by a previous author).
Do not do any duplicate suppression when a source list is created. Instead:
* OP_MADE protects against trying to make the source multiple times.
* A new OP_MARK flag is introduced to suppress duplicates while expanding
the .ALLSRC variable and .USE targets.
This turns the O(n^2) insertion into O(n) in most cases.
This is tested with a `make build' and some special test cases.
* initconn(): use in_addr_t instead of u_int32_t when manipulating IPv6
addresses (and assume anything with ipv6 has in_addr_t; if not, i'll
add an autoconf test for it)
* ai_unmapped(): not all systems have sin_len; so only set #ifdef BSD4_4
* fix some lint
boot images.
The difference compared to the boot images is that these do not contain
sysinst, but do on the other hand contain dump/rdump, restore/rrestore,
scsictl and chio in addition to the other stuff already on the install
floppies.
The images built are
rescue1.fs
rescue2.fs Based on the full INSTALL kernel, on two floppies
rescue-sm.fs Based on INSTALL_SMALL
rescue-ti.fs Based on INSTALL_TINY
- add a new global variable, doing_shutdown, which is nonzero if
vfs_shutdown() or panic() have been called.
- in panic, set RB_NOSYNC if doing_shutdown is already set on entry
so we don't reenter vfs_shutdown if we panic'ed there.
- in vfs_shutdown, don't use proc0's process for sys_sync unless
curproc is NULL.
- in lockmgr, attribute successful locks to proc0 if doing_shutdown
&& curproc==NULL, and panic if we can't get the lock right away; avoids the
spurious lockmgr DIAGNOSTIC panic from the ddb reboot command.
- in subr_pool, deal with curproc==NULL in the doing_shutdown case.
- in mfs_strategy, bitbucket writes if doing_shutdown, so we don't
wedge waiting for the mfs process.
- in ltsleep, treat ((curproc == NULL) && doing_shutdown) like the
panicstr case.
Appears to fix: kern/9239, kern/10187, kern/9367.
May also fix kern/10122.
