directories for that path yet. So, do the check for each component recursively
and succeed if none of the components fall outside our current working
directory.
The problem here is that the archive is too short (< 512 bytes). The
buffer routines, try to read at least 512 bytes, even when we try to determine
what format file we have, which is wrong.
PR/18840: Frederick Bruckman: Fix for PR/18663 incomplete pax symlink handling
This patch makes ``--insecure'' do something. Now if ``--insecure''
is not set (the default) we do a realpath(3) in all the pathnames
that we are trying to create and if either realpath fails, or the
path is outside our working directory, we print a warning and die.
This maybe too strict and might fail on valid archives that create
symlinks and directories in the wrong order.
behavior WRT to patterns lines up with the example in the documentation
and how other implementations do it as well since -A is a non-standard
option/behavior. Fixes items noted in PR#23776
- "cpio -i -t" should list the contents of a file, not extract it.
- Don't extract a file when only option "-d" is given.
Patch supplied by Paul Ripke in PR bin/26513.
an extract. With -h this will cause existing absolute symlinks to be treated
as relative to the current directory.
Helps sysinst handle existing symlinks in the target system.
Remove 'L' from the usage (got spilt into 'h' and 'H' many moons ago)
Add 'S' to usage, and put into correct place in options list.
we can append to it. Modify the code so that file_write is re-entrant,
even in the gnu long name/link hack.
The old code assumed that the buffer already contained the necessary
blocks to satisfy the read file request that contained the long
filename. This is not always the case, specially when we are dealing
with pipes which do shorter reads, thus having more probability
that a long file name will fall across a buffer boundary.
To reproduce, create a tar archive with a lot of gnu-long-names
(pkgsrc/devel/libsigc++2 is a good example), do a tar -tf to get
a list of filenames, compress it and do a tar -tzf to get another
list of the filenames. Notice that the two lists differ.
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')
Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

As mentioned in the previous commit, the switch statement in the longlink()
needed simplification and it was a bit incorrect. Only depend on the passed
type to determine what kind of gnu longlink to produce. Don't try to deduce
it from the archive file type.
- always put the @LongLink tag on the name, not the long-link name.
- pass in what type of long name record we want to create; one for long-name
or long-link name.
XXX: We should get rid of the switch too.
