2012-04-18s3-xattr_tdb: Be nice to xattr_tdb_getxattr callers, return the full blobAndrew Bartlett1-2/+41
In this case, the blob is already in memory, so it is easier to return the full blob to the caller, and let the caller decide if some interface restriction stops the full blob from being passed all the way up the stack. This allows us to quickly write a python wrapper for this xattr storage mechanism. Andrew Bartlett

2012-04-12Fix return_fn when aio was cancelled. We need to return -1, errno = ECANCELED.Jeremy Allison3-0/+15
2012-04-12Fix the same bug reported by Kirill Malkin ↵Jeremy Allison1-4/+24
<kirill.malkin@starboardstorage.com> and fixed by Volker for vfs_aio_fork as ref 0aacdbfada46329e0ad9dacfa90041a1c7dbf3e8. From that change: aio_suspend does not signal the main process with a signal, it just waits. The aio_fork module does not use the signal at all, it directly calls back into the main smbd by calling smbd_aio_complete_aio_ex. This is an abstraction violation, but the alternative would have been to use signals where they are not needed. However, in wait_for_aio_completion this bites us: With aio_fork we call handle_aio_completed twice on the same aio_ex struct: Once from the call to handle_aio_completion within the aio_fork module and once from the code in wait_for_aio_completion. Fix this differently here by not calling directly back into smbd, but using a new function aio_linux_setup_returns() to setup the return values that wait_for_aio_completion() in the main smbd will pick up by calling handle_aio_completd().

2012-04-11build: Add tevent deps for users of tevent callsAndrew Bartlett1-3/+3
This isn't strictly required - this isn't a build break at the moment, but is a good practice to directly depend on the major libraries we use, and helps us to have more fine-grained rather than global dependencies. Andrew Bartlett

2012-04-09s3: Move the aio signal init to the vfs moduleVolker Lendecke1-0/+8
On platforms that don't have an RT signal space, signal initialization fails. aio_fork and aio_pthread don't need the signal, so this would block them from running as well.
2012-04-06Bug found by Herb. blkcnt_t st_ex_blksize is defined as a signed value. When ↵Jeremy Allison1-0/+13
it is on a 32-bit system and defined as a long, then inside vfswrap_get_alloc_size() we cast to a uint64_t. This sign-extends when converting to unsigned, so if the high bit of st_ex_blksize is set we return insane values to clients.

2012-04-03s3-vfs: initial work on posix:eadb moduleAndrew Bartlett2-0/+441

2012-03-31s3-aio-fork: Fix a segfault in vfs_aio_forkVolker Lendecke1-7/+9
aio_suspend does not signal the main process with a signal, it just waits. The aio_fork module does not use the signal at all, it directly calls back into the main smbd by calling smbd_aio_complete_aio_ex. This is an abstraction violation, but the alternative would have been to use signals where they are not needed. However, in wait_for_aio_completion this bites us: With aio_fork we call handle_aio_completed twice on the same aio_ex struct: Once from the call to handle_aio_completion within the aio_fork module and once from the code in wait_for_aio_completion. This patch fixes it in a pretty bad way by introducing flag variables and more state. But the mid-term plan is to replace the posix aio calls from the vfs and do pread_send/recv and pwrite_send/recv at the vfs layer, so this will significantly change anyway.

This removes a dependency on "struct notify_entry" and makes the nature of the API more explicit.

2012-03-22s3:vfs_gpfs: Implement fallocate callback for GPFSChristof Schmitt3-0/+54

2012-03-22s3:vfs_gpfs: Report disk space and usage on GPFS share according to quotasChristof Schmitt1-0/+129
When a client requests the information about free space and space used, adjust the reported values according to quotas in the GPFS file system: - Retrieve quotas for the current user, current group and fileset for the top level of the share. - If the soft block quota grace time has expired, report disk as full. - If a hard block quota has been exceeded, report disk as full. - If none of the hard block quotas been exceeded, report share size and free space according to the lowest limits found in the quotas. - If no applicable hard block quota has been set, report the information from the statfs call. This feature is disabled by default and has to be enabled by setting the option gpfs:dfreequota.
