Subject: [PATCH] src/xlat: remove remnants of unnecessary idx usage in xlookup
As there is no idx saving between calls anymore, there's no need to use
(and update) idx in the XT_SORTED case. Reported by clang as a dead store:
Error: CLANG_WARNING:
strace-5.18/src/xlat.c:84:4: warning[deadcode.DeadStores]: Value stored to 'idx' is never read
* src/xlat.c (xlookup): Remove idx declaration; declare idx inside
of the for loop in the XT_NORMAL case; do not offset x->data and x->size
by offs in the XT_SORTED case and do not update idx upon successful
lookup.
Complements: v5.15~164 "xlat: no longer interpret NULL xlat as continuation"

Subject: [PATCH] util: add offs sanity check to print_clock_t
While it is not strictly needed right now, the code that uses
the calculated offs value lacks any checks for possible buf overruns,
which is not defensive enough, so let's add them. Reported by covscan:

Subject: [PATCH] secontext: print context of Unix socket's sun_path field
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Signed-off-by: Renaud Métrich <rmetrich@redhat.com>
* src/sockaddr.c: Include "secontext.h".
(print_sockaddr_data_un): Print the SELinux context of sun_path field
using selinux_printfilecon.
* NEWS: Mention this change.
* tests/secontext.c (raw_secontext_full_fd, get_secontext_field_fd,
raw_secontext_short_fd, secontext_full_fd, secontext_short_fd): New
functions.
* tests/secontext.h (secontext_full_fd, secontext_short_fd,
get_secontext_field_fd): New prototypes.
(SECONTEXT_FD): New macro.
* tests/sockname.c: Include "secontext.h".
(test_sockname_syscall): Update expected output.
* tests/gen_tests.in (getsockname--secontext,
getsockname--secontext_full, getsockname--secontext_full_mismatch,
getsockname--secontext_mismatch): New tests.

Subject: [PATCH] pathtrace, util: do not print " (deleted)" as part of the
path
In order to allow to discern the unlinked paths from the paths that
do indeed end with " (deleted)".
* src/defs.h (getfdpath_pid): Add deleted parameter.
(getfdpath): Pass NULL as deleted parameter to getfdpath_pid.
* src/largefile_wrappers.h (lstat_file): New macro.
* src/pathtrace.c: Include <sys/stat.h>, <sys/types.h>, <unistd.h>,
and "largefile_wrappers.h".
(getfdpath_pid): Add deleted parameter, check if path ends with
" (deleted)", and if it is, try to figure out if it is a part
of the path by comparing device/inode numbers of the file procfs
link resolves into and the file pointed by the path read; strip
" (deleted)"; set deleted (if it is non-NULL) to true if the fd
is turned out to be deleted and to false otherwise.
* src/util.c (print_quoted_string_in_angle_brackets): Add deleted
parameter, print "(deleted)" after the closing angle bracket if it is
non-NULL.
(printfd_pid): Add deleted local variable, pass it to getfdpath_pid
and print_quoted_string_in_angle_brackets calls.
* tests/fchmod.c: Add checks for a file with " (deleted)" in the path,
update expected output.
* NEWS: Mention the change.

Noteworthy changes in release 5.18 (2022-06-18)
===============================================
+* Changes in behaviour
+ * The "(deleted)" marker for unlinked paths of file descriptors is now printed
+ outside angle brackets; the matching of unlinked paths of file descriptors
+ no longer includes the " (deleted)" part into consideration.
+
* Improvements
* Added an interface of raising des Strausses awareness.
* Added --tips option to print strace tips, tricks, and tweaks

Subject: [PATCH] secontext: fix expected SELinux context check for unlinked
FDs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
selinux_getfdcon open-coded a part of getfdpath_pid since it tries
to do the same job, figure out a path associated with an FD, for slightly
different purpose: to get the expected SELinux context for it. As the previous
commit shows, it's a bit more complicated in cases when the path ends
with the " (deleted)" string, which is also used for designated unlinked paths
in procfs. Otherwise, it may manifest in test failures such as this:
[unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023] fchmod(4</root/rpmbuild/BUILD/strace-5.13/tests/fchmod-y--secontext_full_mismatch.dir/fchmod_subdir/fchmod_sample_file> [unconfined_u:object_r:admin_home_t:s0!!system_u:object_r:admin_home_t:s0], 0600) = 0

that happens due to the fact that the get_expected_filecontext() call
is made against the path with the " (deleted)" part, which is wrong (it
is more wrong than shown above when a file with the path that ends with
" (deleted)" exists). Moreover, it would be incorrect to call stat()
on that path.
Let's factor out the common part of the code and simply call it
from selinux_getfdcon, then use the st_mode from the procfs link.
* src/defs.h (get_proc_pid_fd_path): New declaration.
* src/pathtrace.c (get)proc_pid_fd_path): New function, part
of getfdpath_pid that performs link resolution and processing
of the result.
(getfdpath_pid): Call get_proc_pid_fd_path after PID resolution.
* src/secontext.c (get_expected_filecontext): Add mode parameter, use
it in selabel_lookup call instead of retrieveing file mode using stat()
if it is not -1.
(selinux_getfdcon): Call get_proc_pid_fd_path instead
of open-coding path resolution code, call stat() on the procfs link
and pass the retrieved st_mode to the get_expected_filecontext call.
(selinux_getfilecon): Pass -1 as mode in the get_expected_filecontext
call.
