. leave out dead code from device.c . don't loop doing a receive() after sendrec() - chance of recovering is not high, and can lead to receive()ing a notify() (which can't happen in sendrec()), which is terrible . return status from device when DEV_CANCEL is done on a signal; hardcode EAGAIN to become EINTR though

. Safe I/O, ioctl() and DIAGNOSTICS variants conversion - safe copies, include grant id in DEV_REVIVE messages. . Removal of TTY_FLAGS field (and so O_NONBLOCK support). . Fixed CANCEL behaviour and return code on blocking I/O, previously handled by O_NONBLOCK . Totally removed REVIVE replies, previously still possible on blocking ioctls (REVIVE directly called) and ptys (missing TTY_REVIVE check), removes deadlock bug with FS . Removed obsolete *COMPAT options and associated code

. removed const from putenv() for g++ . added safecopies.c: these are library functions to maintain grant tables in own address space . sys_safecopy.c: interfaces to kernel calls to perform safe copy functions in from or to foreign process . changes in i/o fields (type merged with request) reflected in library functions (sys_out.c, sys_vinb.c, sys_vinl.c, sys_vinw.c, sys_voutb.c, sys_voutl.c, sys_voutw.c) . type merged with request in sys_sdevio, also now accepts offset which is used when a grant is specified (the _DIO_SAFE subtype) . system printf() function changed to send DIAGNOSTICS_S messages, which specify a grant id instead of a direct address for the buffer to be printed; tty and log can then safecopy the buffer
Ben Gras2006-06-20 08:45:04 +00:00

. renamed __str to __makestr to allow for g++ . changed some CMOS ioctl codes to have correct sizes (struct tm instead of u32_t), a disk ioctl code from W to RW, and memory ioctl codes from R to W, needed for proper matching of grant in FS
Ben Gras2006-06-20 08:40:26 +00:00

. introduced DEV_READ_S, DEV_WRITE_S, DEV_SCATTER_S, DEV_GATHER_S and DEV_IOCTL_S as replacements for DEV_READ, DEV_WRITE, DEV_SCATTER, DEV_GATHER and DEV_IOCTL. Instead of a direct address, the *_S commands pass 'grant ids' to the drivers which are referenced through a new set of copy calls (sys_safecopyfrom and sys_safecopyto). in order for this copy to succeed, the grant must have previously been created in the address space of the granter. . bitmap manipulation functions moved to <minix/bitmap.h> . HIGHPOS introduced as field containing high 32 bits of position in device I/O message; TTY_FLAGS no longer used . IO_GRANT field introduced for GRANTs, to replace ADDRESS . REP_IO_GRANT field for un-SUSPEND messages introduced to indicate grant for which I/O was done to disambiguate messages . SYS_SAFECOPYFROM and SYS_SAFECOPYTO introduced as new calls . SYS_PRIV_SET_GRANTS code introduced as a code to set the address and size of the grant table in a process' own address space . 'type' and 'direction' field of _ins* and _outs* I/O functions are merged into one by ORing _DIO_INPUT/_DIO_OUTPUT and _DIO_BYTE/_DIO_WORD etc. This allows for an additional parameter, _DIO_SAFE, which indicates the address in another address space isn't actually an address, but a grant id. Also needs an offset, for which fields had to be merged. . SCP_* are field names for SYS_SAFECOPY* functions . DIAGNOSTICS and GET_KMESS moved to their own range above DIAG_BASE, added DIAGNOSTICS_S which is a grant-based variant of DIAGNOSTICS . removed obsolete BINCOMPAT and SRCCOMPAT options . added GRANT_SEG type for use in vircopy - allows copying to a grant id (without offset) . added _MINIX_IOCTL_* macros that decode information encoded by _IO* macros in ioctl codes, used to check which grants are necessary for an ioctl . introduced the type endpoint_t for process endpoints, changed some prototypes and struct field types to match . renamed protected to prot for g++

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).
