- Introduce support for sticky bit. - Revise VFS-FS protocol and update VFS/MFS/ISOFS accordingly. - Clean up MFS by removing old, dead code (backwards compatibility is broken by the new VFS-FS protocol, anyway) and rewrite other parts. Also, make sure all functions have proper banners and prototypes. - VFS should always provide a (syntactically) valid path to the FS; no need for the FS to do sanity checks when leaving/entering mount points. - Fix several bugs in MFS: - Several path lookup bugs in MFS. - A link can be too big for the path buffer. - A mountpoint can become inaccessible when the creation of a new inode fails, because the inode already exists and is a mountpoint. - Introduce support for supplemental groups. - Add test 46 to test supplemental group functionality (and removed obsolete suppl. tests from test 2). - Clean up VFS (not everything is done yet). - ISOFS now opens device read-only. This makes the -r flag in the mount command unnecessary (but will still report to be mounted read-write). - Introduce PipeFS. PipeFS is a new FS that handles all anonymous and named pipes. However, named pipes still reside on the (M)FS, as they are part of the file system on disk. To make this work VFS now has a concept of 'mapped' inodes, which causes read, write, truncate and stat requests to be redirected to the mapped FS, and all other requests to the original FS. 2009-12-20 21:27:14 +01:00			`#define grp_no m1_i1`

exec() cleanup, generalization, improvement . make exec() callers (i.e. vfs and rs) determine the memory layout by explicitly reserving regions using mmap() calls on behalf of the exec()ing process, i.e. handling all of the exec logic, thereby eliminating all special exec() knowledge from VM. . the new procedure is: clear the exec()ing process first, then call third-party mmap()s to reserve memory, then copy the executable file section contents in, all using callbacks tailored to the caller's way of starting an executable . i.e. no more explicit EXEC_NEWMEM-style calls in PM or VM as with rigid 2-section arguments . this naturally allows generalizing exec() by simply loading all ELF sections . drop/merge of lots of duplicate exec() code into libexec . not copying the code sections to vfs and into the executable again is a measurable performance improvement (about 3.3% faster for 'make' in src/servers/) 2012-05-30 19:34:07 +02:00			`#define msg_frame_len m1_i2`

Moved stime, time, times POSIX calls from FS to PM. Removed child time accounting from kernel (now in PM). Large amount of files in this commit is due to system time problems during development. 2005-05-31 11:50:51 +02:00			`#define stime m2_l1`
libc: add clock_settime() system call. This also adds the sys_settime() kernel call which allows for the adjusting of the clock named realtime in the kernel. The existing sys_stime() function is still needed for a separate job (setting the boottime). The boottime is set in the readclock driver. The sys_settime() interface is meant to be flexible and will support both clock_settime() and adjtime() when adjtime() is implemented later. settimeofday() was adjusted to use the clock_settime() interface. One side note discovered during testing: uptime(1) (part of the last(1)), uses wtmp to determine boottime (not Minix's times(2)). This leads `uptime` to report odd results when you set the time to a time prior to boottime. This isn't a new bug introduced by my changes. It's been there for a while. 2013-03-30 17:59:21 +01:00			`#define clk_id m2_i1`
libc: add adjtime() system call. Implement the adjtime() system call and add a test for it to test69. Additionally, install the adjtime.2 and clock_*.2 man pages. 2013-03-31 03:24:24 +02:00			`#define settime_now m2_i2`

Disabled building rescue driver (no longer needed). Moved allocmem from library to the memory driver. Always put output from within TTY directly on the console. Removed second include of driver.h from tty.c. Made tty_inrepcode bigger. First step to move PM and FS calls that are not regular (API) system calls out of callnr.h (renumbered them, and removed them from the table.c files). Imported the Minix-vmd uname implementation. This provides a more stable ABI than the current implementation. Added a bit of security checking. Unfortunately not nearly enough to get a secure system. Fixed a bug related to the sizes of the programs in the image (in PM patch_mem_chunks). 2006-05-19 14:19:37 +02:00			`#define sysuname_req m1_i1`

libc: add clock_getres()/clock_gettime() system calls. In order to make it more clear that ticks should be used for timers and realtime should be used for timestamps / displaying the date/time, getuptime() was renamed to getticks() and getuptime2() was renamed to getuptime(). Servers, drivers, libraries, tests, etc that use getuptime()/getuptime2() have been updated. In instances where a realtime was calculated, the calculation was changed to use realtime. System calls clock_getres() and clock_gettime() were added to PM/libc. 2013-03-29 22:48:22 +01:00			`#define reply_ntime m2_l2`
