matt 0dc8ee943d Eliminate more commons or redundant declarations. 2002-05-14 02:58:32 +00:00
matt 44b3464a48 debug0, debug1, debug15 are defined elsewhere. XXX there needs to a 
better was of doing this.

matt 0cb85bc7b9 Eliminate commons. 2002-05-12 23:06:27 +00:00
matt e89ff519c5 Make domains extern. 2002-05-12 20:36:58 +00:00
enami af81fabf7c Remove #ifdef DIAGNOSTIC around panic(). It is better than NULL pointer 
dereference.
 2002-05-11 11:56:57 +00:00
enami 3700fdfba4 Don't release the lock on mount point vnode so early when doing update mount. 
Otherwise, race condition occurs (e.g., between mountd(8) and next mount(8)
when multiple update mount command is invoked from shell script).

atatat de7144e830 Maintain a short list of the actual descriptors that were closed and 
log that intead of being ambiguous about which of 0, 1, and/or 2 it
was that was closed.

thorpej f1f51aa2b8 Move code shared by procfs and the kernel proper out of procfs and 
into the kernel proper (renaming functions from procfs_* to process_*).
 2002-05-09 15:44:44 +00:00
enami b42b2c8323 In soreceive(), don't call sopendfree() if MSG_DONTWAIT is set 
since it may sleep.  nfsrv_rcv() tries to do its jobs in softintr
handler as far as possible.

eeh 80ef33c4c1 Back out previous. 2002-05-03 01:22:30 +00:00
thorpej 654768f185 Let the sosend_loan() path be selected at run-time; patch the variable 
use_sosend_loan to enable/disable it.  The SOSEND_LOAN kernel option
now causes it to default to 1.

eeh 89e107d917 Regen. 2002-05-03 00:22:16 +00:00
eeh edc73e0d53 Move the copyout out of ntp_adjtime1 and into the syscall wrapper. 2002-05-03 00:22:15 +00:00
eeh 679cac37b9 Regen. 2002-05-03 00:22:15 +00:00
eeh 9bd29db83b Use #if defined(_LP64) to determine if we're generating 64-bit binaries, 
not #if defined(alpha).
 2002-05-03 00:20:56 +00:00
thorpej 7a49fee765 Add some experimental page-loaning for writes on sockets. It is disabled 
by default, and can be enabled by adding the SOSEND_LOAN option to your
kernel config.  The SOSEND_COUNTERS option can be used to provide some
instrumentation.

Use of this option, combined with an application that does large enough
writes, gets us zero-copy on the TCP and UDP transmit path.

enami e54e7305a2 - Fix more and more white space nits. 
- ANSIfy the last K&R function definition in this file.
 2002-05-02 13:38:57 +00:00
enami cb3d9867b6 Log who invoked the s[ug]id program. Tested by mozilla. 2002-04-28 22:35:19 +00:00
enami 88ee31f5b9 Fix the return value of logioctl() for unhandled ioctl; return EPASSTHROUGH 
instead of -1.  Fix suggested by Andrew Brown.
 2002-04-28 04:13:51 +00:00
thorpej 143be0a01b Use M_READONLY() rathern than a home-grown M_SHAREDCLUSTER(). 2002-04-28 00:53:34 +00:00
enami 9a9bf29bcf A loop to expand file descriptor table and retry is move from fdalloc() 
to caller.  So, no longer need to loop in fdalloc().

christos ce8e03cd9f Avoid file use underflow; thanks to YAMAMOTO Takashi for noticing. 2002-04-24 16:09:24 +00:00
christos 7ad1c0f407 Don't forget to set mature and unuse the file. 2002-04-23 17:20:58 +00:00
christos 1261c89715 From OpenBSD, via FreeBSD: If a set{u,g}id binary is invoked with fd < 3 
closed, open those fds to /dev/null.

XXX: This needs to be fixed in a better way. The kernel should not need to
know about /dev/null or special case 0, 1, 2.

simonb b0b78e1e37 Fix a white-space nit. 2002-04-20 06:04:35 +00:00
gmcgarry acb682fad2 When searching for devices also skip those deleted by userconf. 
Problem reported by uwe.
 2002-04-15 05:30:12 +00:00
christos 7d930e8572 Use SESSHOLD and SESSRELE consistently. 
Add SESSHOLD and SESSRELE to the t_session, so that we don't have dangling
references [inspired by OpenBSD].
 2002-04-12 17:02:33 +00:00
matt 2bf9358fc0 Don't use the tqh_ field names, instead use the correspond TAILQ_* macro. 2002-04-06 08:04:17 +00:00
thorpej 605e664094 vfs_mountroot(): provide more info when we panic. 2002-04-04 01:44:30 +00:00
fvdl c2bf6c9615 Split off the backend of the shmat system call, and find removed segments 
if requested. This enables the linux compat code to be bug compatible
(under Linux, shmat() to a removed segment works).
 2002-04-03 11:53:01 +00:00
fvdl 8cc2d64d7a Include opt_malloc_debug.h so that debug_malloc will actually be used 
when enabled, thankyouverymuch.
 2002-04-03 09:45:22 +00:00
simonb 8bcefa5e82 Fix a typo that stopped this compiling in the !LKM case. 
Remove the buf2 variable from sysctl_sysvipc(), which was only ever
 assigned to but not used.
 2002-04-03 08:06:17 +00:00
rafal 8fcad97302 Fix up linux a.out compat entry after move of emul-related sysctl handler 
to struct emul.
 2002-04-02 23:56:17 +00:00
jdolecek 3ffbb4470d make emul_sysctl() work with emulations loaded via LKM, properly bound check 
name[0]
 2002-04-02 20:21:51 +00:00
jdolecek ebd670f0bc move emulation-specific sysctl hook from struct execsw to struct emul, 
where it belongs
 2002-04-02 20:19:59 +00:00
jdolecek 2e327b16be expose emul_search() 2002-04-02 20:18:06 +00:00
itohy ab5fe01c20 Print ttyinfo *before* (not after) sending SIGINFO to processes. 
This generates more useful information of a process who catches SIGINFO,
rather than always printing "runnable" (the process is marked runnable
because of the signal).
Inspired by the behavior of BSD/OS.
 2002-03-25 04:26:43 +00:00
jdolecek 943f2b4f8a make COMPAT_11 or COMPAT_12 imply EXEC_ELF_NOTELESSS 
use #if for the execsw entries, to allow 'options EXEC_ELF_NOTELESS=0'
  to override this

This addresses kern/13520 and kern/14409 by Matthew Green.
 2002-03-23 09:50:54 +00:00
jdolecek 083f26646d rename EXEC_ELF_CATCHALL to EXEC_ELF_NOTELESS 2002-03-23 09:40:55 +00:00
jdolecek 225f07a8d4 Make sure file descriptor is properly FILE_UNUSE()d in error case 
of writev(2).
Problem found by Alistair G. Crooks.

christos 195539260e emulation specific sysctls. 2002-03-20 00:27:25 +00:00
oki 075769476a Use /emul/pecoff as prefix to run PE/COFF binaries. 2002-03-18 07:11:06 +00:00
christos 18c7399ada oops, forgot to commit the caller of exithook... 2002-03-17 23:41:30 +00:00
christos 22839acdb9 use the exithook mechanism to clean up semaphores. 2002-03-17 22:21:58 +00:00
christos f7d98e2451 - merge all the hook insertion and deletion code so that we don't create 
a fourth copy.
- add exithook to be executed when a process exits.

atatat 31144d9976 Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for 
indicating an unhandled "command".  ERESTART is -1, which can lead to
confusion.  ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4.  No ioctl code should now return -1 anywhere.  The
ioctl() system call is now properly restartable.
 2002-03-17 19:40:26 +00:00
thorpej 53df727d27 Add a new ptrace request, PT_IO, as proposed by Artur Grabowski 
on the <bsd-api-discuss@wasabisystems.com> mailing list.  PT_IO
is a more general inferior I/D space I/O mechanism.  FreeBSD and
OpenBSD have also added PT_IO.

From lha@stacken.kth.se, kern/15945.

simonb 21d2b8b53d We don't need to include <uvm/uvm_extern.h> before <sys/sysctl.h> anymore. 2002-03-17 11:10:43 +00:00
