====== Current list ======
  * Modify Clang/LLD/etc. build to generate Version.inc files or similar rather than hardcoding (e.g. r305088)

====== Outstanding - work ($) ======
Tags of the form reqst######## are bug IDs in $oldwork's bug tracking system.

===== Old current list =====
  - Performance test and commit netmap stats change (netperf cluster)
  - Netmap locking issue reported by witness, on detach
  - %%FreeBSD%%/%%NetBSD%% diff reduction, for OVS port
    - route.h RT_ADVANCE etc.

===== Doc issues =====
  - exit(3) man page return value guidance - too much exit(-1) in proprietary code

===== Solution is understood, work just needs to be done =====

  - BSD licensed smarthost delivery mini MTA
    * Most likely case - dma from %%DragonFly%%
      * https://github.com/corecode/dma (current master repo, github)
      * http://gitorious.org/dma (old gitorious repo)
      * http://gitweb.dragonflybsd.org/dragonfly.git/tree/master:/libexec/dma (in %%DragonFlyBSD%%)
      * Outdated version currently in ports
        * http://www.freshports.org/mail/dma/
      * Current version compiles on %%FreeBSD%% -CURRENT with no change
        * needs trivial stat mtim diff for older releases
      * dma does local delivery, smarthost, or direct MX delivery
        * retry handled for the latter two cases
      * bz@ is working on it
  - Indexed arrays for sh(1) a la ksh/bash -- var[index]=val; echo ${var[index]}
    * Some opposition to this idea - don't want to "bloat" sh(1)
    * I originally had "associative arrays" listed, but indexed arrays are simpler and sufficient for many purposes.  Also Bash only added associative arrays recently.
    * zsh supports indexed arrays (but not associative)
  - lagg failover discarding input -> Tushar
    * disconnect master link
    * switch's mac table assigns mac to backup link
    * reconnect master link
    * switch continues to send frames to backup link
    * lagg discards the frames
    * easy hack: allow accept on any port via sysctl setting
    * better fix: allow lagg to send gratuitous ARP when failover active port changes
    * need link state notification input to lagg to do the latter
  - bootcode / vfs.root.mountfrom cleanup
    * patch is waiting in my tree, reviewed by Attilio
      * (phk) [rootdevnames] should be removable by now.
      * dev/md/md.c:            rootdevnames[0] = "ufs:/dev/md0";
      * ia64/ia64/sscdisk.c:            rootdevnames[0] = "ufs:/dev/sscdisk0";
      * kern/vfs_mount.c:char           *rootdevnames[2] = {NULL, NULL};
      * kern/vfs_mount.c:       if (!vfs_mountroot_try(rootdevnames[0]%%))%%
      * kern/vfs_mount.c:       if (!vfs_mountroot_try(rootdevnames[1]%%))%%
      * nfsclient/bootp_subr.c: rootdevnames[0] = "nfs:";
      * nfsclient/nfs_diskless.c:               rootdevnames[0] = "nfs:";
      * sys/systm.h:extern char *rootdevnames[2];       /* names of possible root devices */
  - TCP support for syslogd
    * plain syslog format over TCP
    * as implemented in syslog-ng
  - schedgraph.py
    * thread names from ps -axH -o paddr,tdaddr,pcomm,tdnam
    * sort by thread name
    * tree view of threads in a process
    * show/hide threads or processes
    * lines between processes in right-hand window don't display in some cases (towards bottom)
    * < > buttons in event window - move to top so you can keep clicking next without moving mouse
    * allow event zoom (magnify selected thread around current time w/o changing overall ticks/pixel)
    * allow absolute ticks, relative ticks, relative time as timestamps
    * add a legend window
    * lend prio event - to thread shows up with just proc name it appears
  - Allow tzsetup to pick UTC or UTC +/- offset zones
    * //reqst00227912//
  - Kernel core handling infrastructure
    * Need a method to determine, from a kernel core,
      * Path to the kernel that was loaded at the time (i.e., sysctl kern.bootfile)
      * Whether or not the kernel now at that path is identical to the one that was running (e.g. md5 hash of kernel file)
    * http://fxr.watson.org/fxr/ident?im=excerpts;i=kernelname
    * reqst00220678 

===== Further investigation or scoping is necessary before beginning work =====

  - <del>Teach {k,}gdb to read gzipped symbols files (idea from brooks)</del> Support ''%%--compress-debug-sections%%''
  - sysv semaphore locking issues
    * does it need a rewrite?
    * some cleanup has happened here, it might be fine now?
  - Big MD root crashes kernel or loader
    * Make big ramdisk: ''%%dd if=/dev/zero of=bsdimage bs=1k count=128k%%''
    * /boot/loader.rc
    * load /boot/kernel/kernel
    * load -t mfs_root /bsdimage
    * [[/JohnBaldwin|JohnBaldwin]]: fixed by bumping up NKPT usually, and now NKPT on i386 is a real kernel option so you can change it more easily
  - other compat32 issues: (maybe just clean up and contribute from $WORKBSD)
    * libcam
    * libgeom / devstat
    * sys/dev/smbus/smb.c
    * PCIOCGETCONF 
  - PR kern/40021 patch to use ld(1) to include a prebuilt md root filesystem instead of writing to a preallocated region
  - serial gdb & conserver improvements
    * conserver, or pty<->conserver connector
    * conserver probably needs a 'passthrough' mode; ^Ec parsing etc. is handled by the server
  - valgrind support
  - hwpmc <del>new CPUs</del>, update/release/incorporate into pmcannotate $WORKBSD profiler
    * adrian looking at our profiler src
    * Ryan also
    * http://code.google.com/p/sprofiler/
  - mount behaviour at mountroot> ufs:ufs/freebsdvm mount -uw / filesystem becomes dirty but does not go rw
    * looks like update changes clean flag and last-mounted string, but then fails when ufs/freebsdvm instead of /dev/ufs/freebsdvm shows up
  - spb perf / FCAPS / 1UX7
  - Audit sys/net/if.c:if_grow() and callers for potential locking issues/race conditions
    * had been fixed in $WORKBSD in the 5.x timeframe, but maybe the race is gone or much less likely now?
  - caching DNS proxy and small DNS server
    * provide hostnames for local network
    * basically what you might expect on a small home router
    * like dnsmasq
    * BSD license would be a plus
  - <@[[/JohnBaldwin|JohnBaldwin]]> emaste: we probably need a separate BSD.32.dist
  - Conflict between utrace records in ld-elf32 and 64-bit kdump
  - pam_diameter - use diameter for AAA, like pam_radius/pam_tacacs
    * Does anyone do this?
  - bsdtar -U option behaviour
    * reqst00174629
    * create a symlink ''%%dirlink -> /some/other/path%%''
    * create a tar file containing directory ''%%dirlink%%''
    * tar -x -P -U file.tar
    * 6.1 left the symlink in place; 6.3 replaces with a directory
  - ifconfig w/ ether and inet config
    * bin/123633 http://www.freebsd.org/cgi/query-pr.cgi?pr=123633&cat=bin
  - em(4) + vlan + polling issue
    * kern/118695 http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/118695
  - lagg / IPv6
    * kern/122954 http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/122954
    * kern/137089 http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/137089
  - First line of vmstat output is incorrect (reqst00198101)
  - Audit ifnet reference counting -- if_ref / vlan / lagg / carp / ...
  - WITNESS for userland (pthreads)
  - kexec (named kload in %%FreeBSD%%: [[http://lists.freebsd.org/pipermail/freebsd-current/2012-November/037906.html]])
  - ksplice ([[http://www.ksplice.com/doc/ksplice.pdf]])

===== Outstanding - Somewhat work related =====
  - Add a nodiskless keyworkd to startup scripts and have /etc/rc not run those for diskless machines
  - Multi device support for loader(8) -- allow simultaneous disk, tftp, nfs, httpfs, etc.
    * Sam said he might look at this
  - HTTP support for pxe loader
    * integrate taleks' work from previous %%GSoC%%
  - Database-backed or in memory DHCP server
    * for booting diskless machines in a test lab
    * be able to change next-server, root-path etc. per host, without rewriting config file and restarting
  - Add support for loading %%FreeBSD%% kernels to QEMU, like it does with Linux kernels
    * direct loading, not from disk image or PXE
  - Automatically unset the boot.nfsroot variables,
    * whenever the loader is compiled with LOADER_TFTP_SUPPORT?
    * if a root md(4) filesystem is loaded?
    * if vfs.root.mountfrom is set and doesn't start with nfs:?
    * via the default loader.conf on the installation media?
    * I don't recall what I was trying to solve here
  - Add SNMP v3 support to bsnmpd
  - Add %%AgentX%% support (RFC2741) to bsnmpd
  - Automatically set vfs.root.mountfrom=ufs:/dev/md0 if a root md(4) filesystem is loaded.

===== Outstanding - personal interest =====
  - SIGINFO handler for newfs_msdos (percentage progress indicator)
  - vnode backed md is in raw format - allow vmdk (vmware) / qcow2(qemu) etc. format as well
    * or perhaps geom_vmdk, geom_qcow2?
  - CUPS / devfs conflict with lpt0
  - media with sector size != 512 (e.g. 2048 byte USB stick)
  - Offer a prebuilt pxeboot_tftp binary compiled with LOADER_TFTP_SUPPORT=YES so that the loader doesn't need to be recompiled.
    * No point if multi-device support gets done.
  - Add twiddle to fsck 
    * jhb mentioned this
    * I thought he had an implementation, but apparently not so
  - Kernel options and modules
    * Can't build ipfw module with forwarding or default to accept
    * sys/netinet/ipfw/ip_fw2.c - #if !defined(KLD_MODULE)
    * looks like a generic problem

===== Todo after 8.0 branch =====
  - Clean up src/lib/libstand/nfs.c vs. netbsd src/sys/lib/libsa/nfs.c
    * http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/lib/libsa/nfs.c?only_with_tag=MAIN
    * also rpc.c, net.c http://www.openbsd.org/cgi-bin/cvsweb/src/sys/lib/libsa/net.c?only_with_tag=MAIN
    * and openbsd 
  - Add debug message to src/sys/boot/common/load_elf.c (symbols)

===== Done =====

  - NFS truncation with non-power-of-two block size (reqst00031351)

<code>
mount -t nfs -orsize=8000,wsize=8000 localhost:/mnt/src /mnt/dst
jot -b 1234567890 1000 > /mnt/src/foo
</code>

  * wc -l /mnt/src/foo -- returns 1000
  * wc -l /mnt/dst/foo -- returns 698
  * Issue is ''%%uio->uio_offset & (biosize - 1)%%'' used as modulo for non-power-of-two
  * Committed as [[http://svnweb.freebsd.org/changeset/base/248500|r248500]]
  - SIOCGIFADDR
  - pivot_root (reroot)
    * To support deployable VMs

===== Abandoned / Overcome by Events =====

  - dump_write API change to take offset (and add di->mediaoffset itself)
    * makes netdumping slightly cleaner
    * **Attilio** to include in cleanup of netdump to HEAD
  - NFS client improvements against SOSS
    * SOSS is a Windows NFS v2 server
  - pxeboot / loader / serial console (RELENG_6 fails, HEAD ok)
  - CPU affinity and binding
    * probably the support in 7.x/8.x is all we want
  - Scheduler work for CPU affinity
  - handle panics from within X "somehow"
