Good. A few more ideas:
* Secure TCP sequence numbers (the random driver has some code for that which doesn't seem to be used anywhere at the moment) * Update the kernel PLL model for the current version of xntpd * Deal with out of virtual memory situations more gracefully - at least, reserve a few last VM pages to root; maybe add VM per user (not per process) limits? Putting processes which fail to allocate memory to sleep might still be better than killing them as long as there is a way to prevent deadlocks. * revoke() system call a la *BSD (to make sure no one holds this device open - not limited to tty devices) * Allocate ftape DMA buffers (96KB!) on first open (free on last close) instead of during driver initialization; needs fixing the memory allocation code first so that it doesn't cause so much fragmentation (and failing to allocate large contiguous areas even though there are still lots of free pages) * Swap files over NFS (for diskless workstations) * Clean up code for swap files - the msdos_smap thing should no longer be necessary ([u]msdos fs has supported bmap for ages); now that we have the loop device, maybe it can be used for swapping and special code for swap files can be eliminated? * Add ability to open serial devices without raising any modem control lines (DTR, RTS) for applications where these lines are misused for special purposes (shutting down the UPS...) * Add ability to register/unregister transfer functions for the loop device - someone might then write the SFS-compatible encryption module (SFS is an encrypted filesystem driver for DOS written by Peter Gutmann - it just encrypts the raw device below the filesystem layer, so it doesn't depend on DOS and should be usable for other filesystems such as ext2 too)
Also, "minimalistic video code" is listed twice - I guess this is the result of heated discussion on this topic :-).
Regards,
Marek
