This looks like a perfect usecase for asprintf

asprintf/vasprintf is non-standard GNU/BSD extension and existing code around already uses strcpy/strcat everywhere. I can try though to use it here if you insist
Some linux distributions adjust path fro kernel to load firmware from using /sys/module/firmware_class/parameters/path. Kernel supports it, teach tqftpserv to respect it too. Signed-off-by: Alexey Minnekhanov <[email protected]>

Some linux distributions adjust path fro kernel to load firmware from using
/sys/module/firmware_class/parameters/path. Kernel supports it, teach tqftpserv to respect it too.Kernel supports only single firmware path specified in firmware_class path. In postmarketOS we created a service script msm-firmware-loader that runs in early boot stage and symlinks all firmware it can find on various device partitions into a single directory, which is then written into
/sys/module/firmware_class/parameters/path.With this patch tqftpserv is able, for example, to successfully serve
wlanmdsp.mbnfile when modem remoteproc is started.Can be used to solve #7
