To: linux-kernel@vger.rutgers.edu Subject: Linux Jobs as of 2.3.99pre6-5 From: Alan Cox <alan@lxorguk.ukuu.org.uk> Date: Tue, 25 Apr 2000 00:40:50 +0100 [Folks please check this for missing stuff and missed fixes] Fixed ----- Tulip hang on rmmod (fixed in .51 ?) Incredibly slow loopback tcp bug (believed fixed about 2.3.48) COMX series WAN now merged VM needs rebalancing or we have a bad leak SHM works chroot SHM back compatibility Intel i960 problems with I2O Symbol clashes and other mess from _three_ copies of zlib! PCI buffer overruns Shared memory changes change the API breaking applications (eg gimp) Finish softnet driver port over and cleanups via rhine oopses under load ? SCSI generic driver crashes controllers (need to pass PCI_DIR_UNKNOWN..) UMSDOS fixups resync (not quite done) Make NTFS sort of work Any user can crash FAT fs code with ftruncate AFFS fixups Directory race fix for UFS Security holes in execve() Lan Media WAN update for 2.3 Get the Emu10K merged In Progress ----------- Merge the network fixes (DaveM) Merge 2.2.15 changes (Alan) Get RAID 0.90 in (Ingo) Finish I2O merge Still some SHM bug reports Fix Exists In -AC Tree ---------------------- Signals leak kernel memory (security) S/390 Merge 1.07 AMI MegaRAID Fix Space.c duplicate string/write to constants Merge the RIO driver (probably do post 2.4.0 as it is large) Fix Exists But Isnt Merged -------------------------- msync fails on NFS Semaphore races Semaphore memory leak Exploitable leak in file locking Mark SGI VisWS obsolete 64bit lockf support TTY and N_HDLC layer called poll_wait twice per fd and corrupt memory ATM layer calls poll_wait twice per fd and corrupts memory Random calls poll_wait twice per fd and corrupts memory PCI sound calls poll_wait twice per fd and corrupts memory sbus audio calls poll_wait twice per fd and corrupts memory Support MP table above 1Gig Finish sorting out VM balancing (Rik Van Riel) To Do ----- Restore O_SYNC functionality Fix eth= command line Trace numerous random crashes in the inode cache VM kswapd has some serious problems vmalloc(GFP_DMA) is needed for DMA drivers put_user is broken for i386 machines (security) Fix module remove race bug (mostly done - Al Viro) Test other file systems on write access_process_mm oops/lockup if task->mm changes Audit all char and block drivers to ensure they are safe with the 2.3 locking - a lot of them are not especially on the open() path. Stick lock_kernel() calls around driver with issues to hard to fix nicely for 2.4 itself IDE fails on some VIA boards (eg the i-opener) PCMCIA/Cardbus hangs, IRQ problems, Keyboard/mouse problem (may be fixed ?) Use PCI DMA by default in IDE is unsafe (must not do so on via VPx x<3) Use PCI DMA 'lost interrupt' problem with some hw [which ?] Crashes on boot on some Compaqs ? pci_set_master forces a 64 latency on low latency setting devices.Some boards require all cards have latency <= 32 usbfs hangs on mount sometimes Loopback fs hangs Problems with ip autoconfig according to Zaitcev SMP affinity code creates multiple dirs with the same name TLB flush should use highest priority Set SMP affinity mask to actual cpu online mask (needed for some boards) pci_socket crash on unload truncate_inode_pages does unsafe page cache operations heavy swapping corrupts ptes Linux sends a 1K buffer with SCSI inquiries. The ANSI-SCSI limit is 255. Linux uses TEST_UNIT_READY to chck for device presence on a PUN/LUN. The INQUIRY is the only valid test allowed by the spec. To Do But Non Showstopper ------------------------- Make syncppp use new ppp code Finish 64bit vfs merges (lockf64 and friends missing) NCR5380 isnt smp safe DMFE is not SMP safe ACPI hangs on boot for some systems Go through as 2.4pre kicks in and figure what we should mark obsolete for the final 2.4 Per Process rtsigio limit Fix SPX socket code Boot hangs on a range of Dell docking stations (Latitude) HFS is still broken iget abuse in knfsd Paride seems to need fixes for the block changes yet Some people report 2.3.x serial problems AIC7xxx doesnt work non PCI ? USB hangs on APM suspend on some machines PCMCIA crashes on unloading pci_socket DEFXX driver appears broken ISAPnP IRQ handling failing on SB1000 + resource handling bug TB Multisound driver hasnt been updated for new isa I/O totally. Compatibility Errors -------------------- Probably Post 2.4 ----------------- per super block write_super needs an async flag addres_space needs a VM pressure/flush callback per file_op rw_kiovec enhanced disk statistics PIII FXSAVE/FXRESTORE support Drivers In 2.2 not 2.4 ---------------------- To Check -------- Truncate races (Debian apt shows it nicely) [done ? - all but Coda] Elevator and block handling queue change errors are all sorted Check O_APPEND atomicity bug fixing is complete Make sure all drivers return 1 from their __setup functions (Done ?) Protection on isize (sct) [Al Viro mostly done] Mikulas claims we need to fix the getblk/mark_buffer_uptodate thing for 2.3.x as well Network block device seems broken by block device changes Fbcon races Fix all remaining PCI code to use new resources and enable_Device VFS?VM - mmap/write deadlock (demo code seems to show lock is there) rw sempahores on page faults (mmap_sem) kiobuf seperate lock functions/bounce/page_address fixes Fix routing by fwmark Some FB drivers check the A000 area and find it busy then bomb out rw semaphores on inodes to fix read/truncate races ? [Probably fixed] Not all device drivers are safe now the write inode lock isnt taken on write File locking needs checking for races Multiwrite IDE breaks on a disk error [minor issue at best] ACPI/APM suspend issue NFS bugs are fixed BusLogic crashes when you cat /proc/scsi/BusLogic/0 Floppy last block cache flush error NFS causes dup kmem_create on reload Chase reports of SMB not working - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu Please read the FAQ at http://www.tux.org/lkml/
