There's a bug in win2k that when NT error codes are not negotiated, the server doesn't response that signatures are mandatory. Since there's (currently) no way turn on signatures in such case, I had to force NT error codes, so that this bug will not occur Signed-off-by: Yehuda Sadeh Weinraub Signed-off-by: Steve French --- fs/cifs/cifssmb.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'fs') diff --git a/fs/cifs/cifssmb.c b/fs/cifs/cifssmb.c index 14de58f..57419a1 100644 --- a/fs/cifs/cifssmb.c +++ b/fs/cifs/cifssmb.c @@ -433,8 +433,8 @@ CIFSSMBNegotiate(unsigned int xid, struct cifsSesInfo *ses) cFYI(1,("secFlags 0x%x",secFlags)); pSMB->hdr.Mid = GetNextMid(server); - pSMB->hdr.Flags2 |= SMBFLG2_UNICODE; - if((secFlags & CIFSSEC_MUST_KRB5) == CIFSSEC_MUST_KRB5) + pSMB->hdr.Flags2 |= (SMBFLG2_UNICODE | SMBFLG2_ERR_STATUS); + if ((secFlags & CIFSSEC_MUST_KRB5) == CIFSSEC_MUST_KRB5) pSMB->hdr.Flags2 |= SMBFLG2_EXT_SEC; count = 0; -- cgit v1.1 From 3ce53fc4c57603d99c330a6ee2fe96d94f2d350f Mon Sep 17 00:00:00 2001 From: Steve French Date: Fri, 8 Jun 2007 14:55:14 +0000 Subject: [CIFS] CIFS should honour umask This patch makes CIFS honour a process' umask like other filesystems. Of course the server is still free to munge the permissions if it wants to; but the client will send the "right" permissions to begin with. A few caveats: 1) It only applies to filesystems that have CAP_UNIX (aka support unix extensions) 2) It applies the correct mode to the follow up CIFSSMBUnixSetPerms() after remote creation When mode to CIFS/NTFS ACL mapping is complete we can do the same thing for that case for servers which do not support the Unix Extensions.
