kleink 372bfc7c08 Calculate returned timeval correctly when using SO_SNDTIMEO/SO_RCVTIME; 
from Koji Imada <koji@math.human.nagoya-u.ac.jp> in PR/3682.

cgd 21bbd49bf2 in vfs_shutdown(), print "syncing disks... " before dropping to spl0(), 
so that if the drop to spl0() causes another panic (e.g. because there's
still some fatal hardware interrupt that's pending) we'll know that we
dropped IPL to sync the disks.

veego 118a503048 Add HW_MACHINE_ARCH for the new sysctl hw.machine_arch which contains the 
cpu class of a machine.

thorpej f160cf5490 Prototype lkmdispatch() in <sys/lkm.h>; all LKMs use it. 1997-05-28 02:44:55 +00:00
thorpej cf30e3e3c9 Prototype lkmexists() in <sys/lkm.h> as some LKMs might need to use it. 1997-05-28 02:41:41 +00:00
thorpej 5b2dc97efd Move the test for "no rootspec and no bootdv" to after we've had a chance 
to set rootspec in the case of "root on ? type nfs" and no bootdv was
found.  From maximum entropy <entropy@tanstaafl.bernstein.com>, PR #3669.

kleink b7ba6138b6 If the pgrp_id argument of TIOCSPGRP (a.k.a. tcsetpgrp()) does not specify 
an existing process group, return EINVAL.

its process group a SIGTTOU signal.

thorpej 92c113aebb Fix printf format botch. 1997-05-17 00:19:02 +00:00
gwr 09da7e273e Eliminate vmspace.vm_pmap and all references to it unless 
__VM_PMAP_HACK is defined (for temporary compatibility).
The __VM_PMAP_HACK code should be removed after all the
ports that define it have removed all vm_pmap references.

kleink 9827bd6dc6 When fstat(2)ing a file descriptor of a local communications domain socket, 
fill the socket's creation time into the stat structure's st_[acm]time fields:
POSIX requires this behavior for pipe(2). N.B.: updating the st_[am]time fields
when reading/writing the pipe is neither required nor implemented, though.
 1997-05-15 17:01:04 +00:00
thorpej e98c5a9b1c Fix two boundary/overflow errors in extent_alloc_subregion(): 
(1): "substart == ex->ex_end" and "subend == ex->ex_start"
     are completely legal parameters for extent_alloc_subregion()
(2): "(subend - substart) + 1" can cause an overflow if the whole
    numeric range is covered by the extent.
Submitted by Matthias Drochner <drochner@zelz26.zel.kfa-juelich.de>
in PR #3119.

db_kill_proc().

mycroft 8e39ee9dad Don't use vaccess() here. 1997-05-08 17:16:15 +00:00
mycroft ae5d73b594 Update for vaccess() change. 1997-05-08 17:08:31 +00:00
mycroft 06fb68217b Oops; fix reversed test for VDIR. 1997-05-08 16:34:54 +00:00
mycroft e3f99a9397 Pass the vnode type to vaccess(), and use it when checking VEXEC. Make sure 
that the mode bits passed to vaccess() and returned by foo_getattr() contain
only permission bits.
 1997-05-08 16:19:43 +00:00
mycroft 07ba5e5ac3 Snapshot of namei() cleanup: 
1) Eliminate all of the null component name special cases; handle runs of
slashes and leading and trailing slashes completely differently.
2) Return ENOENT when doing a lookup through an empty symlink.
3) Enforce that we're doing a lookup through a directory in in chdir() and
lookup() rather than in foo_lookup().

Not yet finished.

mycroft 4d2eb6bb39 GC some code. 1997-05-08 12:17:47 +00:00
mycroft 837a72363d VEXEC -> VLOOKUP, as appropriate. 1997-05-08 10:57:17 +00:00
mycroft 8f5978a181 GC VS[UG]ID and VSVTX, and add a new VLOOKUP, since the semantics are now 
different from VEXEC.
 1997-05-08 10:21:35 +00:00
mycroft d7f33c5e60 va_mode contains stat bits. Use S_IS[UG]ID rather than VS[UG]ID. 1997-05-08 10:19:10 +00:00
gwr 9fa3dabef7 Moved db_show_all_procs() to kern_proc.c 1997-05-07 18:49:10 +00:00
gwr 48c524e63a Add db_kill_proc() for DDB (and move db_show_all_procs here so 
all the "proc" debugging stuff is here in one place).

kleink 29c5707479 * Make chown()/fchown() use a piece of common code to set ownership. 
* Setting the ownership of a file now implies clearing its set-{group,user}-id
  bits.

mycroft 103c7d360d Oops; forgot to GC the last mbuf allocated when out of clusters. 1997-04-28 17:03:58 +00:00
mycroft 2b65c6c346 Delay turning off P_TRACED until the process is actually waited on. It can't 
have any signals delivered while exiting, so this should be okay.  Change the
test for a traced process in wait4() to exclude a process that was started by
the debugger; in this case, only one SIGCHLD should be delivered.
 1997-04-28 13:17:05 +00:00
mycroft 701f15db33 Reinstate P_FSTRACE, with different semantics: 
* Never send a SIGCHLD to the parent if P_FSTRACE is set.
* Do not permit mixing ptrace(2) and procfs; only permit using the one that
  was attached.
 1997-04-28 04:49:27 +00:00
mycroft 43a0dc8b74 Remove remnants of P_FSTRACE, which is no longer used. 1997-04-28 02:51:41 +00:00

case it happens to be doing a WAIT.

mycroft e725c03060 When checking for init, compare against initproc, rather than comparing the 
PID.  No functional difference.

tls 3a98883bd3 Don't allow the time to be set backwards if in highly secure mode, since this would allow inode change times to be manipulated. 1997-04-26 21:22:57 +00:00
mycroft c32418bf82 Fix error in vfs_hang_addrlist() that caused file systems to be exported 
to more subnets than expected when using netmasks.  From Mike Hibler.
 1997-04-25 02:43:10 +00:00
mycroft 9da4efe896 If we fail to allocate a cluster to hold a large packet, simply 
drop it rather than using a chain of tiny mbufs.
 1997-04-24 08:14:04 +00:00
mycroft 5e62a0725b Change previous test slightly. 1997-04-23 20:19:45 +00:00
mycroft b34794e10f Do not return success when checking for execute permission by super-user and no 
execute bits are set.  Also, this test is no longer needed in execve(2).

mycroft 1cf91041df Nuke the old COMPAT_09 truncation of UIDs, GIDs, process and process group IDs. 1997-04-23 18:59:53 +00:00
jtc 2114c082ae In nanosleep, use local error variable when storing rqtp in so that 
an error from a failed tsleep will still be returned to the caller.
