From 14efeb9f956e38d7beaf3fbedb04d3f3bb9ece3a Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Thu, 23 Sep 2010 19:41:05 -0700 Subject: [PATCH] tar: --dereference consistency This closes another race condition, that occurs when overwriting a symlink with a regular file. * NEWS (--dereference consistency): New section. * doc/tar.texi (Option Summary): Describe new --deference behavior. (dereference): Likewise. Remove discussion that I didn't follow, even before --dereference was changed. * src/common.h (deref_stat, set_file_atime): Adjust signatures. * src/compare.c (diff_file, diff_multivol): Respect open_read_flags instead of rolling our own flags. This implements the new behavior for --dereference. (diff_file, diff_dumpdir): Likewise, for fstatat_flags. * src/create.c: Adjust to set_file_atime signature change. * src/extract.c (mark_after_links, file_newer_p, extract_dir): Likewise. * src/incremen.c (try_purge_directory): Likewise. * src/misc.c (maybe_backup_file): Likewise. * src/extract.c (file_newer_p): New arg STP. All callers changed. (maybe_recoverable): New arg REGULAR. All callers changed. Handle the case of overwriting a symlink with a regular file, when --overwrite is specified but --dereference is not. (open_output_file): Add O_CLOEXEC, O_NOCTTY, O_NONBLOCK for consistency with file creation. Add O_NOFOLLOW if overwriting_old_files && ! dereference_option. * src/incremen.c (update_parent_directory): Use fstat, not fstatat; there's less to go wrong. * src/misc.c (deref_stat): Remove DEREF arg. All callers changed. Instead, use fstatat_flags. (set_file_atime): Remove ATFLAG arg. All callers changed. Instead, use fstatat_flags. * src/names.c, src/update.c: Adjust to deref_stat signature change. * src/tar.c (get_date_or_file): Use stat, not deref_stat, as this is not a file to be archived. * tests/Makefile.am (TESTSUITE_AT): Add extrac13.at. * tests/extrac13.at: New file. * tests/testsuite.at: Include it. --- NEWS | 18 +++++- doc/tar.texi | 41 ++++++------- src/common.h | 4 +- src/compare.c | 24 ++------ src/create.c | 4 +- src/extract.c | 140 ++++++++++++++++++++++++++------------------- src/incremen.c | 4 +- src/misc.c | 18 +++--- src/names.c | 4 +- src/tar.c | 2 +- src/update.c | 3 +- tests/Makefile.am | 1 + tests/extrac13.at | 53 +++++++++++++++++ tests/testsuite.at | 1 + 14 files changed, 195 insertions(+), 122 deletions(-) create mode 100644 tests/extrac13.at diff --git a/NEWS b/NEWS index 58fd2ff..1484c55 100644 --- a/NEWS +++ b/NEWS @@ -1,4 +1,4 @@ -GNU tar NEWS - User visible changes. 2010-09-17 +GNU tar NEWS - User visible changes. 2010-09-23 Please send GNU tar bug reports to @@ -33,6 +33,22 @@ supports this.
