* Description fix: SafePerms works on files not dirs.
All uses of SafePerms are on files (and indeed, it would reject
directories which would have +x set).
* Lots of whitespace cleanups.
Enforce everywhere(?) the same indentations for if/fi blocks.
The standard for the Lynis codebase is 4 spaces. But sometimes
it's 1, sometimes 3, sometimes 8.
These patches standardize all(?) if blocks but _not_ else's (which
are usually indented 2, but sometimes zero); I was too lazy to
identify those (see below).
This diff is giant, but should not change code behavior at all;
diff -w shows no changes apart from whitespace.
FWIW I identified instances to check by using:
perl -ne 'if ($oldfile ne $ARGV) { $.=1; $oldfile=$ARGV; }; chomp; if ($spaces) { next unless /^( *)([^ ]+)/; $newspaces=length($1); $firsttok = $2; next unless defined($firsttok); $offset = ($firsttok eq "elif" ? 0 : 4); if ($newspaces != $spaces + $offset) { print "$ARGV:$ifline\n$ARGV:$.:$_\n\n" }; $ifline=""; $spaces=""; } if (/^( *)if (?!.*[; ]fi)/) { $ifline = "$.:$_"; $spaces = length($1); }' $(find . -type f -print0 | xargs -0 file | egrep shell | cut -d: -f1)
Which produced output like:
./extras/build-lynis.sh:217: if [ ${VERSION_IN_SPECFILE} = "" -o ! "${VERSION_IN_SPECFILE}" = "${LYNIS_VERSION}" ]; then
./extras/build-lynis.sh:218: echo "[X] Version in specfile is outdated"
./plugins/plugin_pam_phase1:69: if [ -d ${PAM_DIRECTORY} ]; then
./plugins/plugin_pam_phase1:70: LogText "Result: /etc/pam.d exists"
...There's probably formal shellscript-beautification tools that
I'm oblivious about.
* More whitespace standardization.
* Fix a syntax error.
This looks like an if [ foo -o bar ]; was converted to if .. elif,
but incompletely.
* Add whitespace before closing ].
Without it, the shell thinks the ] is part of the last string, and
emits warnings like:
.../lynis/include/tests_authentication: line 1028: [: missing `]'
* Typo fix.
* Style change: always use $(), never ``.
The Lynis code already mostly used $(), but backticks were sprinkled
around. Converted all of them.
* Lots of minor spelling/typo fixes.
FWIW these were found with:
find . -type f -print0 | xargs -0 cat | aspell list | sort -u | egrep '^[a-z]+$' | less
And then reviewing the list to pick out things that looked like
misspelled words as opposed to variables, etc., and then manual
inspection of context to determine the intention.
The grep statement needs to be modified to prevent tagging port values that contains a value in `SQUID_DAEMON_UNSAFE_PORTS_LIST` but aren't actually the listed port.
