To: linux-kernel@vger.rutgers.edu Subject: Linux 2.3.99pre9-2 JOB list From: Alan Cox <alan@lxorguk.ukuu.org.uk> Date: Thu, 18 May 2000 01:24:25 +0100 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 Paride seems to need fixes for the block changes yet Kernel corrupts fs and gs in some situations (Ulrich has demo code) 1.07 AMI MegaRAID Merge 2.2.15 changes (Alan) Get RAID 0.90 in (Ingo) S/390 Merge NFS DoS fix (security) Merge the RIO driver Fix Space.c duplicate string/write to constants Elevator and block handling queue change errors are all sorted Fix all remaining PCI code to use new resources and enable_Device Make sure all drivers return 1 from their __setup functions (Done ?) Enhanced disk statistics In Progress ----------- Merge the network fixes (DaveM) Finish I2O merge (Intel/Alan) Complete vfsmount merge (Al Viro) Merge removed-buf-open directory stuff into VFS (Al Viro) vmalloc(GFP_DMA) is needed for DMA drivers (Ingo) Fix Exists In -AC Tree ---------------------- Signals leak kernel memory (security) Fix Exists But Isnt Merged -------------------------- msync fails on NFS (probably fixed anyway) Semaphore races (fix in 2.2) Semaphore memory leak (fix in 2.2) Exploitable leak in file locking (Willy) 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 (Ingo) Finish sorting out VM balancing (Rik Van Riel) access_process_mm oops/lockup if task->mm changes (Manfred) Dont panic on boot when meeting HP boxes with wacked APIC table numbering (AC) SMP affinity code creates multiple dirs with the same name (Ingo) Scheduler bugs in RT (Dimitris) TLB flush should use highest priority (Ingo) Set SMP affinity mask to actual cpu online mask (needed for some boards) (Ingo) Fix eth= command line HFS is still broken AIC7xxx doesnt work non PCI ? (Doug says OK, new version due anyway) 8139 + bridging fails Security -------- put_user is broken for i386 machines (security) - sem stuff may be wrong too Fix module remove race bug (mostly done - Al Viro) To Do ----- IDE fails on some VIA boards (eg the i-opener) Find out what has ruined disk I/O throughput. Restore O_SYNC functionality Trace numerous random crashes in the inode cache VM kswapd has some serious problems Test other file systems on write 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 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 ? (may be fixed) pci_set_master forces a 64 latency on low latency setting devices.Some boards require all cards have latency <= 32 Loopback fs hangs Problems with ip autoconfig according to Zaitcev 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 RtSig limit handling bug Fix SPX socket code Boot hangs on a range of Dell docking stations (Latitude) iget abuse in knfsd Some people report 2.3.x serial problems 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. Fix boards with different TSC per CPU and kill TSC use on them Compatibility Errors -------------------- Xterm broke in 2.3.99pre6 (FIONREAD/select loop) Probably Post 2.4 ----------------- per super block write_super needs an async flag addres_space needs a VM pressure/flush callback (Ingo) per file_op rw_kiovec PIII FXSAVE/FXRESTORE support Drivers In 2.2 not 2.4 ---------------------- To Check -------- Check O_APPEND atomicity bug fixing is complete 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 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 - IDE related stuff ? 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 exec loader permissions Locking on getcwd floppy fails on some machines IRDA calls get random bytes before random is set up Some AWE cards are not being found by ISAPnP ?? - 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/
