A typical nfsd call trace is nfsd -> svc_process -> nfsd_dispatch -> nfsd3_proc_write -> nfsd_write ->nfsd_vfs_write -> vfs_writev These add up to over 300 bytes on the stack. Looking at each of these, I see that nfsd_write (which includes nfsd_vfs_write) contributes 0x8c to stack usage itself!! It turns out this is because it puts a 'struct iattr' on the stack so it can kill suid if needed. The following patch saves about 50 bytes off the stack in this call path. Signed-off-by:

Both vfs_getattr and i_op->fsync return error statuses which nfsd was largely ignoring. This as noticed when exporting directories using fuse. This patch cleans up most of the offences, which involves moving the call to vfs_getattr out of the xdr encoding routines (where it is too late to report an error) into the main NFS procedure handling routines. There is still a called to vfs_gettattr (related to the ACL code) where the status is ignored, and called to nfsd_sync_dir don't check return status either. Signed-off-by:

I submitted this one previously - svc_tcp_recvfrom currently returns any errors to the caller, including ECONNRESET and the like. This is something svc_recv isn't able to deal with: len = svsk->sk_recvfrom(rqstp); [...] if (len == 0 || len == -EAGAIN) { [...] return -EAGAIN; } [...] return len; The nfsd main loop will exit when it sees an error code other than EAGAIN. The following patch fixes this problem svc_recv is not equipped to deal with error codes other than EAGAIN, and will propagate anything else (such as ECONNRESET) up to nfsd, causing it to exit.

Split the checkpoint list of the transaction into two lists. In the first list we keep the buffers that need to be submitted for IO. In the second list are kept buffers that were already submitted and we just have to wait for the IO to complete. This should simplify a handling of checkpoint lists a bit and can eventually be also a performance gain. Signed-off-by:

This patch fixes an issue reported by Coverity in kernel/module.c Error reported: Cannot reach this line of code "else return ptr;" Patch description: This is the error path, so 'err' will be negative, the else case is not required, this patch removes it. Signed-off-by:

I missed a use of list_for_each_rcu_safe() in -mm tree. Here is an updated patch to fix it. This time tested on a machine that actually uses IPMI... (Thanks to Serge Hallyn for spotting this.) Signed-off-by:

Did not move the parport interface properly into IEEE1284_PH_REV_IDLE phase at end of data due to comparing bytes with nibbles. Internal phase IEEE1284_PH_HBUSY_DNA became unused, so remove it. Signed-off-by:

Fix potential buffer overflow in case the device ID did not end in semicolon. Also might fail to negotiate back to IEEE1284_MODE_COMPAT in case of failure. parport_device_id did not return what Documentation/parport-lowlevel.txt said, so I changed it to match it. Determining device ID length is overly complicated, but Tim Waugh recalled on linux-parport seeing some buggy device that might need it. Signed-off-by:

Previously invalid types were quietly changed to regular files, but at revalidation the inode was changed to bad. This was rather inconsistent behavior. Now check if the type is valid on initial lookup, and return -EIO if not. Signed-off-by:

In direct_io mode, send at least one page per reqest. Previously it was possible that reqests with zero data were sent, and hence the read/write didn't make any progress, resulting in an infinite (though interruptible) loop. Signed-off-by:

Make the maximum size of write data configurable by the filesystem. The previous fixed 4096 limit only worked on architectures where the page size is less or equal to this. This change make writing work on other architectures too, and also lets the filesystem receive bigger write requests in direct_io mode. Normal writes which go through the page cache are still limited to a page sized chunk per request. Signed-off-by:

Miklos Szeredi authored
Change the way a too large request is handled. Until now in this case the device read returned -EINVAL and the operation returned -EIO. Make it more flexibible by not returning -EINVAL from the read, but restarting it instead. Also remove the fixed limit on setxattr data and let the filesystem provide as large a read buffer as it needs to handle the extended attribute data. The symbolic link length is already checked by VFS to be less than PATH_MAX, so the extra check against FUSE_SYMLINK_MAX is not needed. The check in fuse_create_open() against FUSE_NAME_MAX is not needed, since the dentry has already been looked up, and hence the name already checked. Signed-off-by:

Add support for caching negative dentries. Up till now, ->d_revalidate() always forced a new lookup on these. Now let the lookup method return a zero node ID (not used for anything else) meaning a negative entry, but with a positive cache timeout. The old way of signaling negative entry (replying ENOENT) still works. Userspace should check the ABI minor version to see whether sending a zero ID is allowed by the kernel or not. Signed-off-by:

Add 'frsize' member to the statfs reply. I'm not sure if sending f_fsid will ever be needed, but just in case leave some space at the end of the structure, so less compatibility mess would be required. Signed-off-by:
