* system: add hole punch support to sys_fallocate()David Disseldorp2015-03-091-2/+9
| | | | | | | | If Samba is configured with FALLOC_FL_PUNCH_HOLE support, then allow sys_fallocate() to propogate the flag to syscall invocation. Signed-off-by: David Disseldorp <ddiss@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
* s3/vfs: change fallocate mode flags from enum->uint32_tDavid Disseldorp2015-03-091-10/+11
| | | | | | | | | | | | | | | | | | | | The Linux fallocate syscall offers a mode parameter which can take the following flags: FALLOC_FL_KEEP_SIZE FALLOC_FL_PUNCH_HOLE (since 2.6.38) FALLOC_FL_COLLAPSE_RANGE (since 3.15) FALLOC_FL_ZERO_RANGE (since 3.14) The flags are not exclusive, e.g. FALLOC_FL_PUNCH_HOLE must be specified alongside FALLOC_FL_KEEP_SIZE. Samba currently takes a vfs_fallocate_mode enum parameter for the VFS fallocate hook, taking either an EXTEND_SIZE or KEEP_SIZE value. This commit changes the fallocate hook such that it accepts a uint32_t flags parameter, in preparation for PUNCH_HOLE and ZERO_RANGE support.

* s3: nmbd: Fix bug 10633 - nmbd denial of serviceJeremy Allison2014-06-251-5/+2
| | | | | | | | | | | | | | | | | The Linux kernel has a bug in that it can give spurious wakeups on a non-blocking UDP socket for a non-deliverable packet. When nmbd was changed to use non-blocking sockets it became vulnerable to a spurious wakeup from poll/epoll. Fix sys_recvfile() to return on EWOULDBLOCK/EAGAIN.
