Project:Branches: Chloe/rtems:fix-dosfs-write-cache to rtems/rtos/rtems:main Author: Yang Zhang ## Summary In fat_file_write_fat32_or_non_root_dir(), the FAT file cache was updated even if the first fat_cluster_write() failed and no bytes were completed. \ In that case, cmpltd remains zero, so the expression using cmpltd - 1 may underflow and the cache may be updated with an invalid file cluster or disk cluster mapping. Only update the cache if at least one byte was successfully written. ## Generative AI <!--If you have used AI please use the "AI Contribution" template otherwise leave this blank see our fulls statement at https://www.rtems.org/generative-ai/--> None <!--Default settings, if it is a dropdown it will set after submission--> -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1346 You're receiving this email because of your account on gitlab.rtems.org.
