2013-12-08Tools: hv: remove inclusion of linux/types.hOlaf Hering1-1/+0
With very old libc headers the inclusion of sys/types.h causes conflicts with linux/types.h. Since the latter is not required anyway, remove it from the source files. If any of the headers really needs linux/types.h it has to include it itself. Signed-off-by: Olaf Hering <olaf@aepfle.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-09-26Tools: hv: use single send+recv bufferOlaf Hering1-6/+4
send_buffer is used only once during registration. To reduce runtime memory usage reuse the recv_buffer for registration. Also use NLMSG_LENGTH instead of NLMSG_HDRLEN to take alignment into account.

2013-09-26Tools: hv: cache FQDN in kvp_daemon to avoid timeoutsOlaf Hering1-7/+12
kvp_daemon does some operations which take an unpredicable amount of time. In addition the kernel driver gives the kvp_daemon a 5 second timeout to respond to message from the host. If an operation such as getaddrinfo takes a long time and the timeout triggers then netlink errors occour. As a result of such errors the daemon just terminates and the service becomes unavailable. Idendifying and fixing these shortcomings in the kernel-userland communication protocol will be done in separate patches. This change fixes just one obvious timeout bug. Update kvp_get_domain_name to not return a value, better diagnostic for the consumer of the hostname string, remove trailing newline in error case, use snprintf to not overrun output buffer, get hostname only once and return the cached result.

2013-08-12Tools: hv: correct payload size in netlink_sendOlaf Hering1-1/+1
netlink_send is supposed to send just the cn_msg+hv_kvp_msg via netlink. Currently it sets an incorrect iovec size, as reported by valgrind. In the case of registering with the kernel the allocated buffer is large enough to hold nlmsghdr+cn_msg+hv_kvp_msg, no overrun happens. In the case of responding to the kernel the cn_msg is located in the middle of recv_buffer, after the nlmsghdr. Currently the code in netlink_send adds also the size of nlmsghdr to the payload. But nlmsghdr is a separate iovec. This leads to an (harmless) out-of-bounds access when the kernel processes the iovec. Correct the iovec size of the cn_msg to be just cn_msg + its payload.

2013-08-02Tools: hv: fix send/recv buffer allocationOlaf Hering1-3/+12
hv_kvp_daemon fails to start in current openSuSE 13.1 snapshots because the kvp_send_buffer is too small to hold cn_msg+hv_kvp_msg, the very first sendmsg returns with EFAULT. In addition it fixes the Network info tab in Windows Server 2012R2 in SLES11. Adjust the code in kvp and vss daemon to allocate the needed buffers at runtime. To keep the code simple, the buffer_len includes also the nlmsghdr, although only the recv_buffer needs this extra space. Signed-off-by: Olaf Hering <olaf@aepfle.de> Signed-off-by: K. Y.

2013-03-15tools: hv: daemon should subscribe only to CN_KVP_IDX groupTomas Hozza1-2/+2
Previously HyperV daemon set sockaddr_nl.nl_groups to CN_KVP_IDX. Netlink documentation says: "nl_groups is a bit mask with every bit representing a netlink group number". Since CN_KVP_IDX value is "9" HyperV daemon was receiving Netlink messages also from group number "1" which is used by CGroup Rules Engine Daemon. This caused the daemon to segfault (at least on 2.6.32 kernel). HyperV daemon should set nl_groups to zero and specify multicast group CN_KVP_IDX only by using socket options.
