From decd39b7799a0579ea085b0da0728b6eabd49b38 Mon Sep 17 00:00:00 2001

Subject: [PATCH] [clean] Provide archive abstractions to obfuscate more than
sos archives
This commit removes the restriction imposed on `sos clean` since its
introduction in sos-4.0 to only work against known sos report archives
or build directories. This is because there has been interest in using
the obfuscation bits of sos in other data-collector projects.
The `SoSObfuscationArchive()` class has been revamped to now be an
abstraction for different types of archives, and the cleaner logic has
been updated to leverage this new abstraction rather than assuming we're
working on an sos archive.
Abstractions are added for our own native use cases - that being `sos
report` and `sos collect` for at-runtime obfuscation, as well as
standalone archives previously generated. Further generic abstractions
are available for plain directories and tarballs however these will not
provide the same level of coverage as fully supported archive types, as
is noted in the manpage for sos-clean.

+.TP
+.B \-\-archive-type TYPE
+Specify the type of archive that TARGET was generated as.
+When sos inspects a TARGET archive, it tries to identify what type of archive it is.
+For example, it may be a report generated by \fBsos report\fR, or a collection of those
+reports generated by \fBsos collect\fR, which require separate approaches.
+
+This option may be useful if a given TARGET archive is known to be of a specific type,
+but due to unknown reasons or some malformed/missing information in the archive directly,
+that is not properly identified by sos.
+
+The following are accepted values for this option:
+
+ \fBauto\fR Automatically detect the archive type
+ \fBreport\fR An archive generated by \fBsos report\fR
+ \fBcollect\fR An archive generated by \fBsos collect\fR
+
+The following may also be used, however note that these do not attempt to pre-load
+any information from the archives into the parsers. This means that, among other limitations,
+items like host and domain names may not be obfuscated unless an obfuscated mapping already exists
+on the system from a previous execution.
+
+ \fBdata-dir\fR A plain directory on the filesystem.
+ \fBtarball\fR A generic tar archive not associated with any known tool

Subject: [PATCH] [hostname_map] Add a catch for single-character hostnames
If a log file was truncated at a specific boundary in a string of the
FQDN of the host such that we only get a couple characters before the
rest of the domain, we would previously bodly replace all instances of
that character with the obfuscated short name; not very helpful.
Instead, don't sanitize the short name if this happens and instead
obfuscate the whole FQDN as 'unknown.example.com'.

Subject: [PATCH] [clean,hostname_parser] Source /etc/hosts for obfuscation
Up until now, our sourcing of hostnames/domains for obfuscation has been
dependent upon the output of the `hostname` command. However, some
scenarios have come up where sourcing `/etc/hosts` is advantageous for
several reasons:
First, if `hostname` output is unavailable, this provides a fallback
measure.
Second, `/etc/hosts` is a common place to have short names defined which
would otherwise not be detected (or at the very least would result in a
race condition based on where/if the short name was elsewhere able to be
gleaned from an FQDN), thus leaving the potential for unobfuscated data
in an archive.
Due to both the nature of hostname obfuscation and the malleable syntax
of `/etc/hosts`, the parsing of this file needs special handling not
covered by our more generic parsing and obfuscation methods.

Subject: [PATCH] [hostname] Fix edge case for new hosts in a known subdomain
Fixes an edge case that would cause us to at first not recognize that a
given hostname string is a new host in a known subdomain, but then on
the obfuscation attempt properly recognize it as such and result in an
incomplete obfuscation.
This was mostly triggered by specific patterns for build hosts within
`sos_commands/rpm/package-data`. With this refined check, these types of
matches are properly obfuscated.

Subject: [PATCH 1/3] [hostname] Fix loading and detection of long base domains
Our domain matching has up to now assumed that users would be providing
'base' domains such as 'example.com' whereby something like
'foo.bar.example.com' is a subdomain (or host) within that base domain.
However, the use case exists to provide 'foo.bar.example.com' as the
base domain, without wanting to obfuscate 'example.com' directly.
This commit fixes our handling of both loading these longer domains and
doing the 'domain is part of a domain we want to obfuscate' check.

Adds skips for `/proc/kallsyms` which should never be obfuscated, as
well as any packaging-related log file for the IP parser. Further, do
not obfuscate the `stack` users, as that is a well-known user for many
configurations that, if obfuscated, could result in undesired string
substitutions in normal logging.
