accidentally. Read buffer overruns: The size of the target array (TSOTTA == 10) is a wrong limit to use for scanning the source string. Write buffer overruns: TSOTTA is also a wrong limit to use for copying to the target buffer, since we want to add a NUL terminator afterwards. TSOTTA was also 1 too small for holding both the desired number of visible characters and the NUL. Worked accidentally: There is error in the algorithm that tends to result in the space saved by stripping "irq" not actually being used, but some cases worked accidentally provided "irqN" is near the end of the source string and "N" is only 1 digit. Starting with 5.mumble-CURRENT, "irqN" is at the beginning of the string on all (?) arches that have it and the accidents don't happen. E.g. on i386's, the keyboard irq is now named "irq1: atkbd0<bogus blank padding>" by the kernel, and this name was converted to "1: atkb" -- not only the device number but part of the device name has been lost --, while before 5.mumble the kernel name was "atkbd0 irq1" and systat accidentally preserved the irq number to give "atkbd0 1". The ":" in the string wastes precious space, and stripping "irq" results in descriptions starting with numbers which makes them look too much like counts. This commit just fixes the last problem. |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
