jdolecek 890850dddf Implement linux_sys_nosys() and use it instead of sys_nosys() for 
unimplemented syscalls. Difference is that linux_sys_nosys() doesn't
post SIGSYS to the process. Linux doesn't do that and thus glibc (and
probably other Linux code) doesn't deal with SIGSYS, even through it
generally contains fallback code for ENOSYS case.

This also addresses port-i386/12503, though the issue was already discussed
earlier.

fvdl 879b34ea8c Don't do the ioctl call for the get hw addr case, all the work has 
been done already.

jdolecek 569cf4b764 Use parent's vmspace in linux_e_proc_fork() hook, the child does not 
have vmspace setup yet. This fixes lossage discussed on current-users,
thread "hard lockups with -current and Netscape", and should fix
kern/12433 by <kawamoto@tenjin.org>, maybe also kern/12455.

XXX Threads forked via linux_sys_clone() should share the brk value
XXX if they share vmspace. This needs to be implemented.

itojun c35e5ed1b2 do not dereference p_vmspace, if it is not initialized yet (NULL). 2001-03-22 08:26:14 +00:00
manu 802ed4d55c Removed an unused oldbrk variable in linux_sys_brk() 2001-03-16 07:46:57 +00:00
manu 27a41174dd Made linux_sys_brk() cleaner (no functionnality change) 2001-03-15 23:23:26 +00:00
manu 1208df7bdf Fixed brk() emulation. We now keep track of the processes' idea of the 
break value. See http://mail-index.netbsd.org/tech-kern/2001/03/15/0000.html
for more details.

jdolecek 522f569810 make some more constant arrays 'const' 2001-02-21 21:39:52 +00:00
manu 16bc5b4004 Moved the fix for negative errno returned to userland on the PowerPC to a 
more machine independent fashion
 2001-02-11 20:24:49 +00:00
chs 09cb38f22b expose the definitions of MIN() and MAX() in sys/param.h to the kernel 
and use those in favor of a dozen copies scattered around the source tree.
 2001-02-05 10:42:40 +00:00
itojun 30b4221720 make it compile on alpha. cast pointer to u_long, not int 2001-02-05 04:33:41 +00:00
ross 69e20722b9 Emulate LINUX_TCFLSH with our TIOCFLUSH. Do some CSE. 2001-02-03 19:01:29 +00:00
fvdl 92bf89da0b Oops, remove debugging printf. 2001-02-03 01:23:08 +00:00
fvdl 3d66a69335 For the read subchannel ioctl, don't mix up the data and address formats, 
and always set the track to 0, like Linux does.
 2001-02-03 01:17:38 +00:00
jdolecek 1b91de887e use CHECK_ALT_SYMLINK() for lstat(2) 
don't call stackgap_init() for pwrite(2) and pread(2), it's not necessary
 2001-01-22 21:31:37 +00:00
jdolecek 13ca559d39 Use CHECK_ALT_SYMLINK() instead CHECK_ALT_EXISTS() where appropriate. 
This addresses kern/11757.
 2001-01-22 20:08:03 +00:00
manu fe95c9c3de Moved architecure dependent part of struct linux_termio to architecture 
dependent header files.
 2001-01-20 18:56:41 +00:00
manu d5329fdce7 Cosmetic fix to move powerpc from "guesses" to "know values" 2001-01-19 12:35:47 +00:00
manu e20b81421d Added Linux errno mapping for powerpc 2001-01-19 12:27:13 +00:00
manu 083ffa3b67 Added support for powerpc Linux compatibility 2001-01-19 01:44:46 +00:00
manu ac10cf6946 Added a linux_atexit_signature to match Linux statically linked ELF binaries. It 
searches for a __libc_atexit ELF section, which is specific to Linux
 2001-01-19 01:43:31 +00:00
manu cac0b39302 Added Linux compatibility support for powerpc ports 2001-01-19 01:40:38 +00:00
jdolecek 34c8ae80da constify 2001-01-18 20:28:15 +00:00
tv e58532a4bf No-op commit to force update to a non-"-kk" revision. 2001-01-18 17:47:58 +00:00
fvdl 07ca2a03bf Correct copyright year. 2001-01-10 02:33:47 +00:00
fvdl d772be168f Declare linux_ioctl_blkio and call it from the main routine. 2001-01-10 02:28:38 +00:00
fvdl da9e8a988d Add some BLK* ioctl calls. Currently only the easy and useful ones 
are implemented.
 2001-01-10 02:28:01 +00:00
fvdl 3950869204 Set Linux version to 2.0.38 for now, until the clone + "real time signal" 
problems are fixed.
 2001-01-05 15:31:15 +00:00
fvdl 2d53941bd4 Hardcode what the linux uname() calls return (Linux 2.2.5 is the current 
value). A few major applications check for this (like VMware), and
there is no other way to trick them. Needs a more generic solution
eventually.
 2000-12-29 21:07:16 +00:00
fvdl f90b2fc517 Avoid sign extension problem in offset. 2000-12-29 20:08:54 +00:00
fvdl 77765cf28f Do alternate path checks for link(2). 2000-12-29 20:08:31 +00:00
fvdl 6f552a029f Allow the EJUSTRETURN hack for PTIOCLINUX-passed through ioctl calls. 2000-12-29 20:07:53 +00:00
fvdl 62af6738b1 Use CHECK_ALT_* for chown and lchown, missed in my previous commit. 
Get *id16 calls right; most can be passed through directly, but
some need the 16->32 check for -1 values.
 2000-12-27 22:01:42 +00:00
fvdl e60e785474 Don't do the syscall with modified ioctl command if we've successfully 
done a 'passthrough' ioctl.
 2000-12-22 23:41:16 +00:00
jdolecek e9e91a0fb5 split off thread specific stuff from struct sigacts to struct sigctx, leaving 
only signal handler array sharable between threads
move other random signal stuff from struct proc to struct sigctx

This addresses kern/10981 by Matthew Orgass.
 2000-12-22 22:58:52 +00:00
fvdl 1a09a359eb Add SIOCGIFBR and SIOCSIFBR (more for reference than anything, currently). 2000-12-22 11:24:43 +00:00
thorpej f7a4dd48fd Only include the 16-bit uid/gid stuff if on i386 or m68k. This is a 
little ugly, but hey, so is Linux.
 2000-12-21 20:19:22 +00:00
thorpej e57273c82e Only include the 16-bit chown/fchown/lchown stuff if on i386 or m68k. 
This is a little ugly, but hey, so is Linux.
 2000-12-21 20:15:53 +00:00
fvdl b542c20c5b Fix yet another typo. 2000-12-21 13:37:02 +00:00
fvdl b76b718303 Fix another pasto. 2000-12-19 22:24:03 +00:00
fvdl b7ffc98bf8 Fix pasto in previous. 2000-12-18 16:27:20 +00:00
fvdl 865e7b1375 Pass SIOC* calls that are done on devices (not sockets) through 
without trying to interpret done, as is done on Linux. The device
will get them as PTIOCLINUX, with command and arg in the structure
passed in.
 2000-12-18 14:46:36 +00:00
fvdl 8578d458e5 Define LINUX_SIOCDEVPRIVATE (currently not emulated for sockets). 2000-12-18 14:44:44 +00:00
fvdl 4d193ccde8 Add seperate entries for 16 bit uid/gid calls, so that border cases 
like 0xffff can be handled better (not done yet).
 2000-12-18 14:40:02 +00:00
mycroft b29180b2ff Tighten up the ELF signature checks, and actually look for the ABI tag added 
in newer glibc versions.
 2000-12-15 06:14:21 +00:00
augustss ccf2c891cc Implement sysinfo. 2000-12-13 21:41:23 +00:00
jdolecek 638d27777e add linux_sys_truncate64() 2000-12-12 22:24:56 +00:00
jdolecek daff00c255 add emulation of Linux truncate64(2), ftruncate64(2), *stat64(2) 2000-12-12 19:01:59 +00:00
jdolecek f8d1770316 define EXEC_AOUT (if not defined) before including linux_syscallargs.h, 
to get linux_sys_uselib() prototype
 2000-12-12 17:52:56 +00:00
mycroft f495cd9dc6 Introduce 2 new flags in types.h: 
* __HAVE_SYSCALL_INTERN.  If this is defined, e_syscall is replaced by
  e_syscall_intern, which is called at key places in the kernel.  This can be
  used to set a MD syscall handler pointer.  This obsoletes and replaces the
  *_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL.  If this is defined, certain (deprecated) elements in
  struct emul are omitted.
