usr.bin/tar/ ignores error codes from read() just silently pads nulls
Hi hackers%freebsd.org@localhost & netbsd-users%NetBSD.org@localhost
usr.bin/tar ignores device error codes from read() & silently pads nulls. See
FreeBSD 6.2 6.4 7.3, 8.0, 8.1, & current src/usr.bin/tar/write.c
NetBSD 5.1 & current src/external/bsd/libarchive/dist/tar/write.c
last 3 lines ... bytes_read = read
I filed a send-pr yesterday Mon, 31 Jan 2011 04:52:29 +0100 (CET)
diffs slightly cleaned up here:
Tar author will probably issue cleaner code as soon as he has time.
Meantime, if you may have copied in data without realising media was flakey,
bsdtar will not have warned (though /var/log/messages does), so
you may want to scan with find & a detector eg
