From: alan@lxorguk.ukuu.org.uk (Alan Cox) Subject: BUG LIST: 2.2.0pre7 To: torvalds@transmeta.com, linux-kernel@vger.rutgers.edu Date: Thu, 14 Jan 1999 02:16:27 +0000 (GMT) Directly Exploitable * Procfs has locking errors on mm's in progress * Page table reclamation isnt done. Any user can toast the machine. Unfixed * PPP Oopses with IPX * PPP breaks with Ricochet modems (-vj is a workaround) * PPP trace show driver breakages somewhere * Run two processes that keep rejoining multicast groups on an SMP box - (crash should be fixed by ANK by now) * Spam the box remotely with syn floods and other crap, it leaks memory (this takes a lot of crap to do fortunately) * select/poll magically break at some number of handles without an error (not a problem with default settings) * IDE probe often guesses wrong. Linux is impossible to install on these ranges of PCs. (most are now ok but not all -UMC problem) * isdn4linux is old not CVS version. If its not changing for 2.2.0 include a note about the CVS one. * eata-dma driver crashes the machine if at any instant it cant grab atomic isa dma memory. (Possible fix mark it obsolete and use eata.c which works fine) * Video4linux bttv tends to crash machines grabbing (update to follow tonight) * NTP: 2.2.x is missing the NTP updates still. * You can't mount an ext2fs cdrom. (Block size error). Works in 2.0 Ok on IDE, breaks on SCSI * generic_file_mmap and MSDOS/UMSDOS disagree over who clears blocks * DaveM reports a pile of VMA operations done without locks held. * Need to review all CONFIG_EXPERIMENTAL tags * ide-scsi crashes (HP 8100 for one). Command translation problems can cause crashes. * SCSI error can hold the io lock, causing scsi interrupt handlers to need to sleep- then they panic since its an irq (1542 at least affected) * Quota seems to crash some machines. Unfixed but not vital * NFS client over tcp doesnt work (Now apparently fixed) * NFS readahead is too low * NFS performance to 8K page sized BSD boxes sucks rocks, 2.0.x is about 5 times faster for some cases * IPv6 calls set_multicast_list in the wrong context in progress * TCP fails to handle small SO_SNDBUF/RCVBUF settings * Make xconfig needs layout fixes patch exists _________________________________________________________________ Fixed in -ac patches but not yet in Linus tree For Linus: * AVL tree vm avoids bad perfomance problems * Certain numbers of scsi disks dont seem to work * Some further time fixes * JJ Swap header fix Unsure: * Large file array support (will be required by vendors for several big name products). This is a tricky one. Im wearing too many hats to judge this objectively. Vendors will probably ship this anyway or something similar. Linus doesnt want: * QlogicFC - no big problem, its seperate its clean and vendors can ship it and other driver addons easily as they do now. Its a nobrainer to install of the net. * Message queue support for 32bit sizes. This gets suprisingly tangled for compatibility. 2.3.x we have 64bit fileops and 32bit uid to face so do it all then. * IPI counter ----- Alan - 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/
