22990b77b8 Refactored the internal kernel memory management API. 
It is now permission-oriented, not just user/kernel oriented.

Added <sys/mman.h> with nice PROT_{READ,WRITE,EXEC,FORK} constants.

ec5fa92761 Programmers can now redirect what the errno macro refers to. 2012-07-06 17:18:06 +02:00

887abdfe87 Added a CRC32 function to libmaxsi. 2012-07-02 17:16:23 +02:00

0ab2bbbd1b Finally fixed the loaderbug! 
Programs were crashing randomly at startup on the kthread branch. After some
investigation, it turned out that the programs weren't correctly loaded by
the program loader in rare cases. Although, all investigation showed that
the program loader was correct and so was the interrupt routines (well,
almost, but nothing that could really trigger this). Yada yada, a few months
later I discovered that memcpy(3) was being corrupted by an interrupt handler
(which was correct). Turns out memcpy used stack space it hadn't allocated.
This is a Linux optimization that I had forgotten to disable with
-mno-red-zone in libmaxsi and thus interrupts just overwrote the stack of
optimized functions. Eek!

aac12add54 Added stubs for functions in dlfcn.h. 2012-05-30 23:58:04 +02:00

6eb6a14ace Added stubs for fscanf(3) and mbtowc(3). 
This helps gzip build.

622e0176e3 Added stubs for gmtime(3), localtime(3) and utime(3). 2012-05-29 22:17:27 +02:00
Jonas 'Sortie' Termansen
45981431de Added atexit(3) and on_exit(3). 2012-05-29 22:17:27 +02:00

c5c92d9615 Added ungetc(3). 2012-05-29 22:17:27 +02:00
Jonas 'Sortie' Termansen
b2b54d108d Added getdtablesize(3) for gzip compatibility. 
Remove this once sysconf(_SC_OPEN_MAX) is implemented.

35347ec709 Added raise(3). 2012-05-28 23:10:55 +02:00
Jonas 'Sortie' Termansen
309416c291 Renamed error(3) to gnu_error(3), but with a redirect. 
This fixes compatibility issues with programs that like to make their own
error function. This includes zlib and gzip.

271c64e537 Added a stub locale.h header. 2012-05-28 22:57:03 +02:00
Jonas 'Sortie' Termansen
8ae9f6bd79 Added struct tm and implemented a gettimeofday stub. 
Note that gettimeofday calls uptime() and has no idea what the time was when
the system booted.

341bd73cb0 GCC no longer fixes stdio.h because of va_list. 
Note that for non-ANSI C programs, stdio.h includes stdarg.h which defines
macros that stdio.h wasn't supposed to define.

500f8651bb Prevent GCC from fixing headers that are OK. 2012-05-27 23:46:59 +02:00
Jonas 'Sortie' Termansen
4b252fc55e <libmaxsi/platform.h> now autodetects the current platform. 2012-05-27 23:08:20 +02:00
Jonas 'Sortie' Termansen
87b81080d5 Added sortix_strerror(3) which replaces strerror(3). 
The string returned is now const - POSIX did not allow modifying the string
in any case, conforming applications should not break. If _SORTIX_SOURCE is
defined strerror(3) automatically redirects to sortix_strerror(3),
otherwise the application will receive the traditional function.

9905a2f2d6 Added EINIT, "Not initialized". 2012-05-27 17:20:33 +02:00

e8d75643ea More efficient memcpy(3) for aligned data. 2012-05-27 14:11:35 +02:00
Jonas 'Sortie' Termansen
a75b215fe3 Added fpipe(3) providing pipe(2) through the FILE interface. 2012-05-21 12:52:27 +02:00
Jonas 'Sortie' Termansen
795b1ef4fd Added String::Combine. 
It was previously commented out because it was broken.

92c5533820 Improved the implementation of the exec* functions. 2012-04-30 21:10:02 +02:00
Jonas 'Sortie' Termansen
6367a2352e Added sforkr(2) that controls the child registers as well. 
sfork(2) now calls sforkr(2) with the current registers.

This will prove useful in creating threads, where user-space now can fully
control what state the child will start in. This is unlike the Linux clone
system call that accepts a pointer to the child stack; this is more powerful
and somehow simpler. Note that this will create a rather raw thread; no
thread initization has been done by the standard thread API (when it is
implemented), so this feature shouldn't be used by programmers unless they
know what they are doing.

fork(2) now calls sfork(2) directly. Also removed fork(2) and sfork(2) from
the kernel as they are done using sforkr(2) now. So technically they aren't
system calls right now, but that could always change.

6f36ecf0b3 execve(2) now pushes envp to the new stack and sets up registers. 
This fully implements environmental variables over exec.
 2012-04-04 01:49:14 +02:00
Jonas 'Sortie' Termansen
60b9a84a51 execv(3) now passes environ(7) to execve(2). 2012-04-04 01:38:45 +02:00
Jonas 'Sortie' Termansen
33645eb347 <unistd.h> now declares environ(7) if _WANT_ENVIRON. 
Note that it is very bad style of programs to access it directly.

05b29ce25a Renamed rfork(2) to sfork(2) to avoid compatibility issues. 
sfork is much like rfork except sharing is default for everything.

Eventually, I'll make a rfork(3) wrapper function around sfork(2) to
provide compatibility to BSD programs.

I don't like Linux clone(2): that's some messy function.

dd5157da6a Implemented setenv(3), putenv(3), getenv(3), clearenv(3), sortix_getenv(3), 
unsetenv(3), envlength(3), getenvindexed(3), and environ(7).

This provides the user-space foundation for environmental variables.

Note that this works over fork(2), but not execve(2) yet.

5d59f0ed03 Added EBOUND. 2012-04-02 20:24:56 +02:00
Jonas 'Sortie' Termansen
95a088fec5 Added a dummy implementation rfork(2) equal to fork(2). 
Note that in my implementation, you share per default, unless you ask.

cd0e402bbb Added {,l,ll,imax}abs(3). 2012-03-27 16:36:55 +02:00

9ab0bc5474 Added {,p}{read,write}{all,least}(3). 2012-03-24 15:34:30 +01:00
Jonas 'Sortie' Termansen
c62eb09cdc Added stubs for pread(2) and pwrite(2). 
These are not implemented yet because the current kernel design is bad.

However, I need the stubs for other code.

757184fd5c Added EEOF. 2012-03-24 15:19:16 +01:00

db79994e64 Refactored all the sortix headers into a include directory. 
Also got rid of trailing white space. That corrupted .git/.

Big ass-commit because of recovered .git directory.

2cdeb575f8 Renamed EACCESS to EACCES. 
Stupid POSIX.

Jonas 'Sortie' Termansen
366cc2549a Added the stdio_ext(3) API. 
The API is available in <stdio.h> without __ prefix if _SORTIX_SOURCE.
