Subject: [PATCH 1/2] linux_usbfs: Accept sysfs attributes not terminated with
newline
Benjamin Berg reports that some CI systems that simulate sysfs devices
are causing libusb to report errors because such systems are not
conforming to the sysfs pattern of terminating attribute values with a
newline character. Reduce the severity of encountering such
non-conforming attibute values from an error that prevents enumeration
to a warning message.
Closes #857

Subject: [PATCH] linux_usbfs: Fix parsing of descriptors for
multi-configuration devices
Commit e2be556bd2 ("linux_usbfs: Parse config descriptors during device
initialization") introduced a regression for devices with multiple
configurations. The logic that verifies the reported length of the
configuration descriptors failed to count the length of the
configuration descriptor itself and would truncate the actual length by
9 bytes, leading to a parsing error for subsequent descriptors.
Closes #825

Subject: [PATCH 2/2] linux_usbfs: Gracefully handle buggy devices with a
configuration 0
The USB spec states that a configuration value of 0 is reserved and is
used to indicate the device in not configured (e.g. is in the address
state). Unfortunately some devices do exist that violate this and use 0
as the bConfigurationValue of the configuration descriptor.
Improve how the Linux backend handles such non-conformant devices by
adding special handling around the configuration value 0. Most devices
will not require this special handling, but for those that do there is
no way to distinguish between the device being unconfigured and using
configuration 0.
Closes #850

Subject: [PATCH 02/18] core: Add non-null annotations to avoid static analyser
warnings
It is only valid to call these inline functions with non-null values.
However, static analysis may complain that the functions may dereference
the pointer incorrectly if it is only looking at the function itself
rather than including the surrounding code.
Add the appropriate annotiations to both fix warnings and improve
detection of bugs in API users.

It is guaranteed that entry->next and entry->prev are non-null for a
list item that is part of a list. The static analyser might be confused
though, so add an appropriate assert in case debug mode is enabled.

Subject: [PATCH 04/18] core: Fix incorrect free if reallocating to zero size
A realloc to a size of 0 is equivalent to a free call. As such, in that
case free'ing the original pointer would result in a double free. Fix
this by adding a check that the new size if larger than zero.

Subject: [PATCH 05/18] linux_usbfs: Work around static analyser thinking fd is
leaked
Static analysis using coverity is detecting the file descriptor handle
potentially being leaked in some situations. The code itself is actually
sound, but coverity is not correctly following the fact that fd can be
compared against wrapped_fd.
Fix this by introducing an fd_close variable which is compared to a
fixed value to decide whether to close the fd. Also switch to a goto
pattern rather than returning from different places.

Subject: [PATCH 08/18] core: Tell coverity that libusb_open does not free
Internally, libusb_open does an unref in an error case. coverity doesn't
seem to notice that this is balanced with the earlier ref, and thinks
that the passed in device may be free'ed. Annotate the function to
prevent misdetections.
An alternative would be to only take the reference after checking for
the error, but the code is idiomatic as-is.

The workaround to sleep 10ms if a device node has not yet been created

I suppose, in the long run this might be fixed by removing the netlink

This warning is a false positive. It occurs because the HANDLE_CTX

it is. However, in these cases the handle is guaranteed to not be NULL
and adding an explicit non-NULL check does not avoid the warning.

# upstream libusbx has merged back with libusb and is now called libusb again
# but we already have a libusb package for the old libusb-compat-0.1, renaming
# that to libusb-compat while at the same time giving this its name is a bit
# tricky, lets stick with the libusbx name for now
