u9fs: fix misuse of Fcall.afid in p9any authentication module. (from sources patch/u9fs-afid)
U9fs(4) misuses Fcall.afid in its p9any authentication module.
The afid field of Fcall structure is only valid with Tauth or Tattach.
Tread, Twrite, Tclunk should use rx->fid instead. It's been lucky so
far to get the job done because rx->afid survives from previous
Tauth/Tattach. The issue pops up when several authentications happen
concurrently.
Test case:
u9fs = 'host with u9fs on tcp!*!564'
9fs $u9fs; for(i in 1 2 3 4 5 6 7 8){ 9fs $u9fs & }; wait
Should:
no errors
Should not:
mount failed: authentication failed
