2015-10-09Change all tame callers to namechange to pledge(2).Theo de Raadt
2015-10-04Also needs "rpath" for some circumstances.Theo de Raadt
2015-10-03gzip can use tame "stdio wpath cpath fattr". this blocks a lot ofTheo de Raadt
system behaviours such as forking, execve, sockets, etc. in theory this extended by parsing the arguments first, and creating the whitepathlist. the pathlist probably needs to be directory-oriented, rather than exact path of files, because a gzip file may specify the filename it wants (and that won't be available until it is opened, and partially parsed). anyone want to give this a try? gzip was an early goal for capsicum. who is running a capsicum gzip?
2015-08-30Ignore setuid/setgid settings from a compress/gzip file; original CSRGTheo de Raadt
code. Found by trondd exercising coverage of tame in gzip. ok guenther millert kettenis

2015-06-25Put fts_close() where missing.Masao Uebayashi
Not bugs in short-lived commands that call exit() -> _exit() immediately, but for idempotency. Originally found in ls(1) by Valgrind. Changes for other commands are from deraadt@. Reviewed by me, tested in snapshots. OK deraadt@
2015-05-03Preserve times to nanosecond precision instead of just microsecond.Philip Guenther
Prefer to set attributes by fd for regular files, and not follwing symlinks for others. ok brynet@ millert@
2015-04-09Both more and less accept options beginning with '+'.Todd C. Miller

2015-02-01KNF whitespace fix and handle funopen error case.Tobias Stoeckmann
ok millert
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)
2014-10-08userland reallocarray audit.Doug Hogan
Replace malloc() and realloc() calls that may have integer overflow in the multiplication of the arguments with reallocarray(). ok deraadt@

2014-05-07When you want more, you say "more". When you want less, you say "less".Vadim Zhukov
When you don't get what you asked for, you get angry. When you add a tiny bit, it should be "more" or "less" still, or you'll get angry. So lets make zmore(1) call more(1) and zless(1) call less(1), as it's supposed to be. okay and input from ingo@, no objections from author AKA millert@

2014-01-27Remove the no-op flags -L and -V from compress(1), these optionsTodd C. Miller
come from GNU zip and they were never in compress(1) until we added gzip(1) support to it. Also remove -g flag from gzip(1) as it is non-standard and only makes sense in compress(1). Joint work with jmc@ and sobrado@. OK jmc@, sobrado@

2014-01-26- document for uncompress and zcat exit status of 0 or >0 onlyJason McIntyre
- kill an unneccessary Pp that created double vertical space - mention that posix marks these apps xsi - add uncompress -V to the list of extensions - document that posix stipulates a limit of 14 for -b, even though it permits 15 and 16 ok sobrado millert

2012-09-30When outputting to stdout and compressing would grow the file, exitTodd C. Miller
normally instead of with a value of 2. Also avoids unlinking the file "stdout" in the current directory in this case. OK miod@ sthen@ henning@ beck@

2011-09-22Remove the rcsid which were intentionally skipped in the "purge of 2009"Theo de Raadt

mark these utilities as being either optional (SD/FR/UP); or as being compliant only with XPG4 (XSI); strip.1 and talk.1 are tweaked purely for consistency; thanks otto for feedback

2008-10-08For "gunzip -N", the name stored in the gzip header has no directory,Todd C. Miller
so write the uncompressed file in the same directory we would use were the -N option not specified. Closes PR 5224
2008-08-20Use and report errors that inflate(3) can return, instead ofMarco Pfatschbacher
aborting silently, and pretending everything went alright. This lets gzip(1) (especially gzip -t) detect truncated archives and curruptions that violate the structure of the zlib format. Unquiet compress(1) in zless/zmore, so the user has a chance to see errors on corrupted archives. OK millert@, markus@

2008-07-27an enum specifier is more elegant than a set of #defines;Igor Sobrado

2008-07-05each utility must have its own usage and an unique set of options.Igor Sobrado
diff written by millert based on a previous one by me; millert's diff has a much better style and adds support for different sets of options for each utility. ok millert@
2008-02-25For the -l flag, set testmode to 1 instead of incrementing it. FixesTodd C. Miller
a bogus error message problem when the -t and -l flags are used together. OK miod@
