tests: wrap $TS_{TOPDIR,SELF} in "." cmdline with double quote chars

2022-11-23T07:09:48+00:00

The command lines used for this change:

  $ cd tests/ts
  $ sed  -i -e 's|. $TS_SELF/|. "$TS_SELF"/|'  $(grep --exclude='*~' -lr -e '^\. \$TS_SELF/')
  $ sed -i -e 's|. $TS_TOPDIR/functions.sh|. "$TS_TOPDIR"/functions.sh|'  $(grep --exclude='*~' -lr -e '^\. \$TS_TOPDIR/functions.sh')

lsfd: use TYPE column to show cooked file types

2022-09-09T17:29:20+00:00

lsfd has two exclusive requirements：

A. show quickly understandable information in limited display area, and
B. provide primitive raw information for post-process tools.

For the purpose A, summarizing information is nice. However, the
summarized information is not suitable for tools.

To satisfy the both requirements, I plan introducing new fields
with a new convention.

STTYPE represents the type information returned from stat(2).
TYPE is the same as STTYPE but two exceptions; TYPE is filled with
PROTONAME value if the target fd is a socket, or with AINODECLASS
value if the target fd is a anonymous inode.

Below an example output:

    $ ./lsfd -o COMMAND,TYPE,STTYPE,NAME -Q '(TYPE != STTYPE)'  | head
    COMMAND                TYPE STTYPE NAME
    systemd         UNIX-STREAM   SOCK UNIX-STREAM:[25493]
    systemd         UNIX-STREAM   SOCK UNIX-STREAM:[25493]
    systemd                UNIX   SOCK UNIX:[31445]
    systemd           eventpoll   UNKN anon_inode:[eventpoll]
    systemd            signalfd   UNKN anon_inode:[signalfd]
    systemd             inotify   UNKN anon_inode:inotify
    systemd             timerfd   UNKN anon_inode:[timerfd]
    systemd           eventpoll   UNKN anon_inode:[eventpoll]
    systemd             inotify   UNKN anon_inode:inotify

STTYPE, column for tools, is printed only when the column is specified
with -o option.

tests: (lsfd) normalize protoname before comparing

This is a follow-up commit to a60ac11fe0087584f37329b4733edfade3452c64.

To make this test case more portable, this change makes the test case
accept "UINX-DGRAM" in addition to "UINX", too.

tests: (lsfd) make DGRAM socketpair to mitigate the change of protoname

2021-11-27T00:52:53+00:00

The protoname for a socket can be get from its xattr slot of
/proc/$PID/fd/$FD.

The protoname for (AF_UNIX, SOCK_STREAM) sockets was changed
from "UNIX" to "UNIX-STREAM" in
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=94531cfcbe79c3598acf96806627b2137ca32eb9

As the result, the test case, mkfds-socketpair doesn't work well on a
newer kernel.

To mitigate the impact of the change in the kernel, use (AF_UNIX, SOCK_DGRAM)
for making a socket pair.

In the commit, the protoname of (AF_UNIX, SOCK_DGRAM) sockets was also
changed to "UNIX-DGRAM". However, it was renamed back to "UNIX" in
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0edf0824e0dc359ed76bf96af986e6570ca2c0b9

Partially close #1511.
