* cifs: have cifs_new_fileinfo take a tcon argJeff Layton2010-09-293-14/+16
| | | | | | | | To minimize calls to cifs_sb_tcon and to allow for a clear error path if a tcon can't be acquired. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
* cifs: add cifs_sb_master_tcon and convert some callers to use itJeff Layton2010-09-298-32/+42
| | | | | | | | | | | | | At mount time, we'll always need to create a tcon that will serve as a template for others that are associated with the mount. This tcon is known as the "master" tcon. In some cases, we'll need to use that tcon regardless of who's accessing the mount. Add an accessor function for the master tcon and go ahead and switch the appropriate places to use it.

* cifs: add function to get a tcon from cifs_sbJeff Layton2010-09-2913-71/+74
| | | | | | | | | | When we convert cifs to do multiple sessions per mount, we'll need more than one tcon per superblock. At that point "cifs_sb->tcon" will make no sense. Add a new accessor function that gets a tcon given a cifs_sb. For now, it just returns cifs_sb->tcon. Later it'll do more.

| | | | | | | | | | Eventually, we'll have more than one tcon per superblock. At that point, we'll need to know which one is associated with a particular fid. For now, this is just set from the cifs_sb->tcon pointer, but eventually the caller of cifs_new_fileinfo will pass a tcon pointer in.

* cifs NTLMv2/NTLMSSP ntlmv2 within ntlmssp autentication codeShirish Pargaonkar2010-09-298-53/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attribue Value (AV) pairs or Target Info (TI) pairs are part of ntlmv2 authentication. Structure ntlmv2_resp had only definition for two av pairs. So removed it, and now allocation of av pairs is dynamic. For servers like Windows 7/2008, av pairs sent by server in challege packet (type 2 in the ntlmssp exchange/negotiation) can vary. Server sends them during ntlmssp negotiation. So when ntlmssp is used as an authentication mechanism, type 2 challenge packet from server has this information. Pluck it and use the entire blob for authenticaiton purpose. If user has not specified, extract (netbios) domain name from the av pairs which is used to calculate ntlmv2 hash. Servers like Windows 7 are particular about the AV pair blob. Servers like Windows 2003, are not very strict about the contents of av pair blob used during ntlmv2 authentication. So when security mechanism such as ntlmv2 is used (not ntlmv2 in ntlmssp), there is no negotiation and so genereate a minimal blob that gets used in ntlmv2 authentication as well as gets sent. Fields tilen and tilbob are session specific. AV pair values are defined. To calculate ntlmv2 response we need ti/av pair blob. For sec mech like ntlmssp, the blob is plucked from type 2 response from the server. From this blob, netbios name of the domain is retrieved, if user has not already provided, to be included in the Target String as part of ntlmv2 hash calculations. For sec mech like ntlmv2, create a minimal, two av pair blob. The allocated blob is freed in case of error. In case there is no error, this blob is used in calculating ntlmv2 response (in CalcNTLMv2_response) and is also copied on the response to the server, and then freed. The type 3 ntlmssp response is prepared on a buffer, 5 * sizeof of struct _AUTHENTICATE_MESSAGE, an empirical value large enough to hold _AUTHENTICATE_MESSAGE plus a blob with max possible 10 values as part of ntlmv2 response and lmv2 keys and domain, user, workstation names etc. Also, kerberos gets selected as a default mechanism if server supports it, over the other security mechanisms.

The reason mac_key was changed to session key is, this structure does not hold message authentication code, it holds the session key (for ntlmv2, ntlmv1 etc.). mac is generated as a signature in cifs_calc* functions.

* cifs: fix broken oplock handlingSuresh Jayaraman2010-09-293-10/+9Star
| | | | | | | | | | | | | | | | cifs_new_fileinfo() does not use the 'oplock' value from the callers. Instead, it sets it to REQ_OPLOCK which seems wrong. We should be using the oplock value obtained from the Server to set the inode's clientCanCacheAll or clientCanCacheRead flags. Fix this by passing oplock from the callers to cifs_new_fileinfo(). This change dates back to commit a6ce4932 (2.6.30-rc3). So, all the affected versions will need this fix. Please Cc stable once reviewed and accepted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libata depends on scsi_host_template for module reference counting and sht's should be owned by each low level driver. During libahci split, the sht was left with libahci.ko leaving the actual low level drivers not reference counted. This made ahci and ahci_platform always unloadable even while they're being actively used. Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for each low level ahci driver. stable: only applicable to 2.6.35.

This commit fixes the problem. This fix is only a workaround. For a real fix, cpu_sibling_mask() should be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be included directly. This fix is currently not possible because asm/smp.h defines cpu_sibling_mask() unconditionally and is included directly from many source files.

However it does this using 'int', but syscalls return 'long' (and thus signed 64-bit on 64-bit machines). So it could trigger false-positives on 64-bit as written. So fix it to use 'long'.

In addrconf_init we call ipv6_addr_label_init which calls register_pernet_subsys for the ipv6_addr_label_ops structure. But if module loading fails, or if the ipv6 module is removed, there is no corresponding unregister_pernet_subsys call, which leaves a now-bogus address on the pernet_list, leading to oopses in subsequent registrations. This patch cleans up both the failed load path and the unload path. Tested by myself with good results.

When TP loses link, the driver switches to non-existing AUI port (which reports that carrier is always present). Connecting TP back generates LinkPass interrupt but de_media_interrupt() is broken - it only updates the link state of currently connected media, ignoring the fact that LinkPass and LinkFail bits of MacStatus register belong to the TP port only (the chip documentation says that). This patch changes de_media_interrupt() to switch media to TP when link goes up (and media type is not locked) and also to update the link state only when the TP port is used. Also the NonselPortActive (and also SelPortActive) bits of SIAStatus register need to be cleared (by writing 1) after reading or they're useless.

After adding pci_set_master(), the driver oopsed immediately on resume - because de_clean_rings() is called on suspend but de_init_rings() call was missing in resume. Also disable link (reset SIA) before sleep (de4x5 does this too). Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Acked-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: David S.
