2024-05-21remove prototypes with no matching function and externs with no varJonathan Gray
partly checked by millert@
2022-12-04userspace: remove vestigial '?' cases from top-level getopt(3) loopsScott Soule Cheloha
getopt(3) returns '?' when it encounters a flag not present in the in the optstring or if a flag is missing its option argument. We can handle this case with the "default" failure case with no loss of legibility. Hence, remove all the redundant "case '?':" lines. Prompted by dlg@. With help from dlg@ and millert@.

2022-03-31man pages: add missing commas between subordinate and main clausesChristian Weisgerber
jmc@ dislikes a comma before "then" in a conditional, so leave those untouched. ok jmc@
2021-11-07nm: add some .text.* support for symbolsSebastien Marie
.text.* are generated when using -ffunction-sections. makes nm(1) to correctly identify the function symbols as N_TEXT. found while debugging librsvg build error, where some symbols where not found by libtool(1) (which is using nm(1)). ok gkoehler@

2020-02-08correct Research Unix edition "appeared in" use in HISTORYJonathan Gray
Starting from "Combined Table of Contents" in Doug McIlroy's "A Research UNIX Reader" a table of which edition manuals appeared in. Checked against manuals from bitsavers/TUHS and source from TUHS where available. Ingo points out there are cases where something is included but not documented until a later release. bcd(6) v6 v7 printf(3) v2 v4 abort(3) v5 v6 system(3) v6 v7 fmod(3) v5 v6 ok schwarze@
2019-09-06More Version 1 AT&T UNIX history.Ingo Schwarze
This became possible because copies of the original v1 manuals have shown up on the Internet some time ago. Reminded by Sevan Janiyan <venture37 at geeklan dot co dot uk>.

2015-06-23This patch ensure that when an error is detected, the freed variables insemarie
elf_symloadx() are reinitialised. Else show_file() in nm.c will used these variables, even if they has just been freed. (nm.c +689). Problem found by afl. ok miod@
2015-06-23This patch ensure that e_shentsize (sections header's size in bytes) issemarie
big enough to fill at least one Elf_Shdr. While here, inverts calloc() arguments to be calloc(nmemb, size), according to fread() call after. This problem was found with afl, with e_shentsize=1. ok miod@

2015-01-16Replace <sys/param.h> with <limits.h> and other less dirty headers whereTheo de Raadt
possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

2011-09-28Support symbols in .tbss and .tdata ELF sectionsUwe Stuehler
With this change nm(1) prints the expected symbol type ('B' or 'D') for variables in the .tbss and .tdata sections respectively, instead of '?'. This would be what binutils do for non-automatic variables that are marked as thread-local with the __thread attribute in GCC. help and ok miod@, guenther@

2009-10-28rcsid[] and sccsid[] and copyright[] are essentially unmaintained (andTheo de Raadt
unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms
