What this page is for

This page documents known breakage with the 2.2 series Linux kernels and the about-to-be-released Debian 2.1 (slink), as well as Debian 2.0 (hamm). If you plan to use these packages with kernel 2.2, and are affected by these issues you should use the potato versions of these packages.

Things not yet fixed in Potato (Debian unstable)

• diald
  Acts funny - Sometimes can't tell that connections were closed, etc. Fixed in latest upstream. See Bug#32592 as well as Bug#16590.
• acct
  lastcomm prints out corrupted information, then segfaults. It must be recompiled against 2.2.x headers to work with 2.2.x, which would in turn break 2.0.x compatibility. The maintainer is waiting for the upstream author to allow the same acct binary to work with both kernels. See Bug#18314 and Bug#24085.
• lsof-2.0.35
  Ordinarily you'd need to recompile lsof for a new kernel version, but that's not good enough for 2.2.x. It's been fixed in v4.40 upstream. See Bug#25637, Bug#31935, and Bug#33176.
  
• xosview
  Breaks with 2.2.2. Fixed upstream. See Bug#33795
  

Upgrading from Slink (Debian 2.1)

• dhcpcd
  Breaks completely - see Bug#26596
  
• dhcp-client-beta
  Potato version includes a new /etc/dhclient-script that works with 2.2.
• sysutils
  procinfo segfaults.
  
• netbase
  
  • ifconfig won't show aliased interfaces - fixed in potato.
    
  • "ipchains -Z -L -n -v" silently fails to clear packet/byte counters - also fixed in potato, see Bug#33348.
    
  • For those of you who are running 2.2 kernels but don't wish to make the leap to glibc 2.1 and IPv6, a 2.2-compatible netbase package linked against glibc 2.0 has been made available at http://www.debian.org/~rcw/2.2/netbase/
    
• pcmcia-cs
  Can't compile pcmcia-source for a 2.2.x kernel. Fixed in 3.0.9.
  
• wanpipe
  2.0.1 is incompatible with 2.2.x kernels. Note that the 2.0.4 version in potato is also incompatible with 2.0.x kernels, however there is a patch for kernel 2.0.36 included with the wanpipe package.
  
• netstd
  bootpc only recieves a BOOTP reply correctly when the interface has already been configured. See Bug#33386.

Upgrading from Hamm (Debian 2.0)

Everything above applies, as well as:

• isdnutils
  Example scripts don't use the correct route commands for 2.2. This will cause problems for users on dynamic IPs. Upgrading to potato will not fix this problem automatically (package upgrades won't affect your own scripts), however the example scripts in potato work correctly. A hamm-compatible version of this package is available at http://www.debian.org/~rcw/2.2/isdnutils/(This is currently the version in potato).
  
• util-linux
  mkswap can't initialize swap partitions greater than 132MB.
  
• rvplayer
  Breaks. The binary is actually still broken, however the slink rvplayer install package ships with a shared library to work around the problem.
  

Other notes

• smbfs
  smbfs stopped working with kernel 2.1.70. You should get the smbfsx package, included in hamm, which contains /usr/bin/smbmount-2.1.x. The command-line syntax has changed between these two versions, for a wrapper script please look at http://www.wittsend.com/mhw/smbmount.html.
  
• netbase
  
  • You should now be using ipmasqadm instead of ipautofw.
    
  • You should be using ipchains instead of ipfwadm now. The netbase package includes a 'ipfwadm-wrapper' program which is a drop-in replacement for ipfwadm - make sure to modify your firewall/masq setup scripts!
    
  • Don't use a route command unless you need to specify something other than what the kernel sets up for you. If you do, remember to include a netmask. It's no longer optional.
    
• CUA devices
  The /dev/cua* devices, obsolete under kernels 1.2 and 2.0, are no longer supported by kernel 2.2.x. You should switch to the /dev/ttyS* devices.
  
• dhcp-client-beta
  You will need to compile your kernel with the CONFIG_PACKET and CONFIG_FILTER options in order for the new dhcp-client-beta package to work. Also make sure you are using the DHCLIENT method with pcmcia-cs if you use pcmcia and dhcp together.
• NFS fcntl-locking
  If you want to take advantage of kernel 2.2's client-side support for NFS fcntl-locking, you'll want to get rpc.statd, available at ftp://ftp.de.kernel.org/pub/linux/daemons/statd/statd-0.2.4.tar.gz. rpc.statd is not yet packaged.
