[PATCH v3 0/4] cdc-acm: reassemble fragmented notifications

[Tobias Herzog]

USB devices may have very limitited endpoint packet sizes, so that
notifications can not be transferred within one single usb packet.
This patchset adds the ability to reassemble notifications that are
transmitted fragmented.


v3:
 * reordering patches (security issues first)
 * fixed possible alignment bug
 * allocate buffer with size=2^x
 * additional code comments + fixed typos in commit messages

v2:
 * reuse an allocated buffer for further notifications
 * fixed issues with endianess
 * check buffer allocation (kmalloc)
 * don't use hard coded size of notification-header
 * fixed typo + code structure (unneeded goto)

Tobias Herzog (4):
  cdc-acm: fix possible invalid access when processing notification
  cdc-acm: reassemble fragmented notifications
  cdc-acm: log message for serial state notification
  cdc-acm: remove unused element of struct acm
