Prior to this change, if the input string terminates exactly when `len`
characters have been output, the libx52util_convert_utf8_string function
returns an error of `-E2BIG`, even though the buffer is sufficiently
large. Because the output buffer is not expected to be NUL terminated,
this additional character can be safely placed in the output buffer
without overrun.
This change checks for a non-NUL character when the index matches or
exceeds the output buffer length, and only then will it return -E2BIG.
The test case uses a negative value to force a test of the ID to string
functions in the abnormal case. However, this ends up with accessing the
expected array with a negative index. This is technically undefined
behavior, and may cause failures in some systems. This change ensures
that the negative values will be mapped directly to the unknown
string, without having to perform a negative index.
The libx52util_convert_utf8_string function manually converts the UTF-8
string into the character map supported by the X52/X52Pro MFD. However,
there was a bug when handling malformed UTF-8 input. If the state
machine thinks it is at the start of a word and receives malformed UTF-8
input (between 0x80 and 0xC0), it will ignore the characters, but it
will not reset the entry to the map_root location, thereby causing
subsequent characters to be dropped.
This change ensures that the entry is reset to map_root[*input] after
skipping over an invalid UTF-8 sequence.
As part of improving the privacy around the software, even though time
zone is not considered PII, it's still coarse location data that we
don't need at all. By using UTC, we can eliminate even this last bit of
identifying information from the bug reports.
In order to comply with recent privacy laws such as GDPR and CCPA, the
bug report utility has been updated to remove personally identifiable
information such as device serial number and system hostname from the
output.
In addition, this change also adds a PRIVACY.md file which describes how
this project handles data, in compliance with GDPR/CCPA. Documentation
is updated to link to the privacy document as well.
Version metadata was not updated to reflect the new version. This fixes
the version metadata and updates the changelog file to reflect the
reason why the older version was deprecated.
In macos-14, programs that rely on cmocka need to specify CMOCKA_CFLAGS
as part of their CFLAGS. This has not been an issue so far on older
versions of macOS, or on any release of Ubuntu, but it should be done to
ensure that the library headers can be found.
macos-12 builds fail with the following error message:
ld: warning: -undefined dynamic_lookup may not work with chained fixups
This causes the overall build status to be marked as fail, even though
macOS builds are not treated as failing the build. Also, macOS 12 is
going to effectively be end-of-lifed in November 2024, so it's not worth
spending the time to look into this.
Cmocka is optional for the builds, but the absence of cmocka causes the
Daemon build to fail when running `make check`. This commit addresses
that issue, while keeping tests that don't need cmocka.
`calloc` requires the count to be the first argument, and the size
parameter to be the second argument. However, this has not really caused
issues in the past, and older compilers were not so strict about it.
However, newer compilers (at least GCC 14) triggers a warning on this
and causes the build to fail.
Fixes#52
macOS 12 builds are currently failing with the following error:
ld: warning: -undefined dynamic_lookup may not work with chained fixups
This is causing the overall CI to fail, therefore, I am disabling it
until such time that this can be fixed.
When building the package for PPA, gcc throws errors indicating that
some variables may be used uninitialized. This is not a real problem
that shows up during the CI build, but only when building using
dpkg-buildpackage.
This change adds some dummy initialization so that it avoids triggering
those warnings during debuild/dpkg-buildpackage.
The notify module controls the logging settings for the notify socket
code. While missing this doesn't cause any impact to the notify code, an
invalid module name sent on the command socket could cause the daemon to
crash with a NULL pointer access.
