* [CIFS] clean up server protocol handlingSteve French2008-11-13
| | | | | | | | | | | | | | | | | | We're currently declaring both a sockaddr_in and sockaddr6_in on the stack, but we really only need storage for one of them. Declare a sockaddr struct and cast it to the proper type. Also, eliminate the protocolType field in the TCP_Server_Info struct. It's redundant since we have a sa_family field in the sockaddr anyway. We may need to revisit this if SCTP is ever implemented, but for now this will simplify the code. CIFS over IPv6 also has a number of problems currently. This fixes all of them that I found. Eventually, it would be nice to move more of the code to be protocol independent, but this is a start. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
* [CIFS] remove unused list, add new cifs sock list to prepare for ↵Steve French2008-11-13
| | | | | | | | | | | | | | | mount/umount fix Also adds two lines missing from the previous patch (for the need reconnect flag in the /proc/fs/cifs/DebugData handling) The new global_cifs_sock_list is added, and initialized in init_cifs but not used yet. Jeff Layton will be adding code in to use that and to remove the GlobalTcon and GlobalSMBSession lists.

* [CIFS] Fix cifs reconnection flagsSteve French2008-11-13
| | | | | | | | | | | | | | | | | In preparation for Jeff's big umount/mount fixes to remove the possibility of various races in cifs mount and linked list handling of sessions, sockets and tree connections, this patch cleans up some repetitive code in cifs_mount, and addresses a problem with ses->status and tcon->tidStatus in which we were overloading the "need_reconnect" state with other status in that field. So the "need_reconnect" flag has been broken out from those two state fields (need reconnect was not mutually exclusive from some of the other possible tid and ses states). In addition, a few exit cases in cifs_mount were cleaned up, and a problem with a tcon flag (for lease support) was not being set consistently for the 2nd mount of the same share CC: Jeff Layton <jlayton@redhat.com> CC: Shirish Pargaonkar <shirishp@us.ibm.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
* [CIFS] Can't rely on iov length and base when kernel_recvmsg returns errorSteve French2008-11-03
| | | | | | | | | | | | When retrying kernel_recvmsg, reset iov_base and iov_len. Note comment from Sridhar: "In the normal path, iov.iov_len is clearly set to 4. But i think you are running into a case where kernel_recvmsg() is called via 'goto incomplete_rcv' It happens if the previous call fails with EAGAIN. If you want to call recvmsg() after EAGAIN failure, you need to reset iov." Signed-off-by: Shirish Pargaonkar <shirishp@us.ibm.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

| * [CIFS] Reduce number of socket retries in large write pathSteve French2008-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CIFS in some heavy stress conditions cifs could get EAGAIN repeatedly in smb_send2 which led to repeated retries and eventually failure of large writes which could lead to data corruption. There are three changes that were suggested by various network developers: 1) convert cifs from non-blocking to blocking tcp sendmsg (we left in the retry on failure) 2) change cifs to not set sendbuf and rcvbuf size for the socket (let tcp autotune the buffer sizes since that works much better in the TCP stack now) 3) if we have a partial frame sent in smb_send2, mark the tcp session as invalid (close the socket and reconnect) so we do not corrupt the remaining part of the SMB with the beginning of the next SMB. This does not appear to hurt performance measurably and has been run in various scenarios, but it definately removes a corruption that we were seeing in some high stress test cases.

| * | tracing, ring-buffer: add paranoid checks for loopsSteven Rostedt2008-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While writing a new tracer, I had a bug where I caused the ring-buffer to recurse in a bad way. The bug was with the tracer I was writing and not the ring-buffer itself. But it took a long time to find the problem. This patch adds paranoid checks into the ring-buffer infrastructure that will catch bugs of this nature. Note: I put the bug back in the tracer and this patch showed the error nicely and prevented the lockup. Signed-off-by: Steven Rostedt <srostedt@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| * | ftrace: use kretprobe trampoline name to test in outputSteven Rostedt2008-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: ia64+tracing build fix When a function is kprobed, the return address is set to the kprobe_trampoline, or something similar. This caused the output of the trace to look confusing when the parent seemed to be this "kprobe_trampoline" function. To fix this, Abhishek Sagar added a test of the instruction pointer of the parent to see if it matched the kprobe_trampoline. If it did, the output would print a "[unknown/kretprobe'd]" instead. Unfortunately, not all archs do this the same way, and the trampoline function may not be exported, which causes failures in builds. This patch will compare the name instead of the pointer to see if it matches. This prevents us from depending on a function from being exported, and should work on all archs. The worst that can happen is that an arch might use a different name and then we go back to the confusing output. At least the arch will still build.

Using ioremap at runtime is impractical as it is too slow. This new set of interfaces uses atomic mappings on 32-bit processors and a large static mapping on 64-bit processors to provide reasonable 32-bit performance and optimal 64-bit performance.

The issue is documented also in: http://bugzilla.kernel.org/show_bug.cgi?id=11742.

In short, the driver fails to mmap MMIO aperture (PCI resource #2). I've found that kernel's __pci_mmap_make_offset() returns EINVAL. It checks whether user attempts to mmap more than the resource length, which is 0x1000 bytes in our case. But PAGE_SIZE on SPARC64 is 0x2000 and this is what actually is being mmaped. So __pci_mmap_make_offset() failed for this PCI resource. Signed-off-by: Max Dmitrichenko <dmitrmax@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

I always wanted to mimick powerpc's definition of TASK_SIZE, which is simply TASK_SIZE_OF(current) and that also fixes the warning. Signed-off-by: David S. Miller <davem@davemloft.net>
