[linux-cifs-client] Re: [Fwd: Re: cifs on ARM?]

[Steven French]

Your trace shows the byte count is three bytes off (three bytes early) in
the first smb (negotiate protocol) request that the cifs client sent.
The code looks right - but we may be seeing a problem here with the
compiler recognizing the packing of nested structures due to its alignment
requirement.   Note that these few fields in the protocol itself - in the
smb header are not aligned.   Presumably the issue is one or more of
compiler confusion:
      - with pragma pack (1)   (although it handles it earlier in the
writing to the smb_header)
      - inside a typedef struct
      - in a nested struct
may be confusing the compiler on arm - might be helpful to get a listing ie
      make fs/cifs/cifssmb.s
and/or
      objdump -S cifssmb.o

Could you forward those to me?
