manu 0e9a3e0d43 - We now use irix_sys_mmap instead of svr4_sys_mmap 
- initial support for MAP_AUTOGROW flag. When mapping beyond the end of file is
requested with MAP_AUTOGROW, if pages beyond the end of file are touched, the
file should be resized. We are not able to emulate this yet, so we immediatly
resize the file to fit the whole mapping.
- implements mmap64

manu 4678e0b326 Fixed functions to get the number of CPU in sysmp() and systeminfo(). The 
problam was that when hw_sysctl() is used, the result is supposed to be
in userland
 2002-04-20 21:25:01 +00:00
manu ded3c31a9c On IRIX, fcntl F_FREESP, F_ALLOCSP, F_FREESP64 and F_ALLOCSP64 commands 
ignore the len argument. We now correctly emulate the behavior of these
commands.

manu e67d46d7af Added one more system call: msync 2002-04-20 16:56:28 +00:00
manu 21d2265eea Fixed mistakes in irix_sys_fcntl() (missing breaks in case statement) 2002-04-20 16:20:12 +00:00
manu d5ed80d9c6 The IRIX usinit(3) function expects a page of memory to be available at 
address 0x200000 (disasembling usinit shows that this address is hardcoded in
libc). It uses it for locks and semaphres.

We therefore allocate this page of memory, to prevent IRIX process from
faulting when thay call usinit(3).

manu 1f32c2b1c4 One more unsupported feature: SGI_SATCTL 2002-04-20 07:43:35 +00:00
manu 829bfed008 Added missing irix_misc.c 2002-04-20 07:42:32 +00:00
manu 5261d673c9 Added getpgrp/setpgrp. 
setpgrp is stolen from compat/sunos. It should probbaly be moved to
/compat/common
 2002-04-16 20:15:47 +00:00
manu 08948f97d1 Added sysconf(SC_IP_SECOPTS) 2002-04-16 20:15:03 +00:00
manu 28a3cfe032 Do not restore SR on sigreturn: this could enable the user process to gain 
unpropre privileges.
 2002-04-15 20:48:12 +00:00
manu f8c12b3107 IRIX provide a signal trampoline in libc, we now use it. 
- the signal trampoline address is given to the kernel by a sigaction()
  fourth argument
- we introduce an irix_emuldata structure to keep track of the signal
  trampoline address
- we don't support per-sigaction signal trampolines, we only do per-process
- now that we use the IRIX libc signal trampoline, we do not have to handle
  the errno update from the signal trampoline
- it is possible that IRIX 5 signal delivery works too, since theses binaries
  will come with their own signal trampoline

manu c56e133974 More comments on the new signal frame/trampoline 2002-04-13 10:52:59 +00:00
manu 5ee554064d Reworked IRIX signal delivery so that ucontext is used instead of sigcontext 
when SA_SIGINFO is used. The IRIX process will hence find the expected
information using the third argument of the signal handler.

We do not provide code and siginfo yet.
 2002-04-12 18:44:57 +00:00
manu 78583a4567 Always define SA_SIGINFO, and keep track of it in SVR4 emulation. This is 
needed for IRIX signal delivery.
Approved by Christos.

christos bd432c1642 PR/16236: Joachim Koenig-Baltes: Linux emulation connect requires IPV6. 
Apparently the sockaddr len fix was only compiled when IPV6 was enabled.
 2002-04-08 14:00:31 +00:00
christos 866ad0f73f PR/16231: Ben Harris: m68k does not compile. 2002-04-08 13:27:37 +00:00
manu fb46073720 backed out the irix_siginfo field name change: we need different field names 
to avoid collision with svr4_siginfo #define si_signo  _info._signo and
friends.
 2002-04-06 22:58:43 +00:00
manu 8e8b498d9c Changed irix_siginfo field names to make them closer to svr4 names (and to 
original IRIX names too)
 2002-04-06 18:08:31 +00:00
christos e9c4f70b2f use lsi_ like all other linux emulations. 2002-04-04 22:17:29 +00:00
tron d09c25ca9a Set default kernel version of Linux emulation to 2.4.18 on the i386 port. 
It has been successfully tested using SuSE 7.3 libraries and binaries with
many applications.
 2002-04-04 09:32:11 +00:00
christos cb483bd247 make this compile on archs that don't define linux signals. 2002-04-03 17:18:21 +00:00
christos f28b55d327 provide missing types for arch's that don't have specific linux_types.h 2002-04-03 17:13:32 +00:00
christos aa3369abe2 don't bail out if we don't have an arch/siginfo.h because we are being used 
from userland.
 2002-04-03 17:02:12 +00:00
tron 9121bc2ec4 Fix a cut and paste error in the emulation of getresgid(2): it returned 
the effective user id as effective group id.
 2002-04-03 14:28:36 +00:00
fvdl 221107a13b Use shmat1(), and tell it to find removed segments. 2002-04-03 11:54:37 +00:00

christos fa33d13de9 Don't blow up if we don't have a machine dependend linux_signal.h. 
kdump includes linux_signo.c
 2002-04-02 23:25:07 +00:00
christos eda21311fd save/restore fs and gs; this should be pulled up. 2002-04-02 22:32:16 +00:00
manu 4bca6e2fd0 Added fsync 2002-04-02 20:29:52 +00:00

manu 062e23b4e2 Added IRIX fcntl(F_GETBSDLK) and fcntl(F_GETBSDLKW) 2002-04-02 19:58:38 +00:00
manu 456cced40e Removed one debug line that was committed by mistake 2002-04-01 15:45:16 +00:00

(copied from the native version, not tested yet)
 2002-04-01 13:42:36 +00:00
christos 840887afee bring the reverse signal mapping array into linux_signo.c 2002-03-31 22:40:16 +00:00
christos ac29fb3782 make signal array handling uniform, and put signal arrays in a separate 
file. This is simular to errno array handling.
 2002-03-31 22:22:43 +00:00
christos 018a4082cc - #undef DPRINTF for files that are included from other files. 
- more debugging for socketcalls
- fix sa_len if AF_INET; somehow we get passed 28 instead of 16?
 2002-03-29 20:49:40 +00:00
kent dad83731c1 pecoff_misc.c: Remove compat functions. 
pecoff_sys*.[ch]: regen
 2002-03-29 17:04:46 +00:00
christos c9e808f0ee 1. fill in the ldt.sd_xx field, for total compat with linux. 
2. in setregs, use gdt's instead of ldt's because linux wants to play with
   all the ldts. Apparently linuxthreads uses ldt's to allocate space for
   pthread_t's.
 2002-03-29 17:01:49 +00:00
kent e6ef08a13e Exclude all compat syscalls. 2002-03-29 17:00:43 +00:00
manu 4a466c8fec Added proper locks when calling uvm_swap_stats() 2002-03-29 09:06:54 +00:00
manu 2dd126f08e Fixed the swap block size problem: the swap block size as used in struct 
swapent, or as seen in userland, is dbtob(1), which turns to be 512 for all
arch for now.

In struct swapdev, there is another field for block size. This value is private
to uvm_swap.c and is only used for swap I/O on regular files. It is equal to
the underlying device block size and it is not necessarily 512.
 2002-03-28 18:45:28 +00:00
manu 9278164721 - now reports accurate swap object size with swapctl(SWAP_STATS) 
- Added two more swapctl commands: GETFREESWAP and GETSWAPVIRT.

There is a problem in the way swap block size are found here. See comment
in get_block_size().
