In order to lay the foundation for 1G EEE support, several segments of code which are common to both 1G and 10G EEE configurations were extracted from the 10G EEE configuration flow to their own functions. E.g., bnx2x_eee_initial_config, bnx2x_eee_advertise, bnx2x_eee_disable, etc. The rest of the EEE functions were relocated and placed in a single, continuous section of the file. Signed-off-by:

This patch aligns the EEE status with that of all other link properties, by changing the way its accessed - instead of a direct read to the shared memory, each function maintain its own copy locally. Signed-off-by:

a lot of code has either the memset or an inefficient copy from a static array that contains the all-zeros Ethernet address. Introduce help function eth_zero_addr() to fill an address with all zeros, making the code clearer and allowing us to get rid of some constant arrays. Signed-off-by:

When a policy expiration is triggered from user space the request travels through km_policy_expired and ultimately into xfrm_exp_policy_notify which calls build_polexpire. build_polexpire uses the netlink port passed to km_policy_expired as the source port for the netlink message it builds. When a state expiration is triggered from user space the request travles through km_state_expired and ultimately into xfrm_exp_state_notify which calls build_expire. build_expire uses the netlink port passed to km_state_expired as the source port for the netlink message it builds. Pass nlh->nlmsg_pid from the user generated netlink message that requested the expiration to km_policy_expired and km_state_expired instead of current->pid which is not a netlink port number.

It is a frequent mistake to confuse the netlink port identifier with a process identifier. Try to reduce this confusion by renaming fields that hold port identifiers portid instead of pid. I have carefully avoided changing the structures exported to userspace to avoid changing the userspace API. I have successfully built an allyesconfig kernel with this change. Signed-off-by:

This patch defines netlink_kernel_create as a wrapper function of __netlink_kernel_create to hide the struct module *me parameter (which seems to be THIS_MODULE in all existing netlink subsystems). Suggested by David S. Miller. Signed-off-by:

Replace netlink_set_nonroot by one new field `flags' in struct netlink_kernel_cfg that is passed to netlink_kernel_create. This patch also renames NL_NONROOT_* to NL_CFG_F_NONROOT_* since now the flags field in nl_table is generic (so we can add more flags if needed in the future). Also adjust all callers in the net-next tree to use these flags instead of netlink_set_nonroot. Signed-off-by:

Refactoring the bind code lets us use a common driver_info struct for all supported devices, simplifying the code a bit. The real advantage is that devices using the CDC ECM interface layout now also can be added dynamically using the new_id sysfs interface. This simplifies testing of new devices. Signed-off-by:

QMI requests exceeding 1500 bytes are possible and device firmware does not handle fragmented messages very well. It is therefore necessary to increase the maximum message size from the current 512 bytes. The protocol message size limit is not documented in any publicly known source, but the out of tree driver from CodeAurora use 4 kB. This is therefore chosen as the new arbitrary default until the real limit is known. This should allow any QMI message to be transmitted without fragmentation, fixing known issues with GPS assistance data upload. Signed-off-by:

Passing uids and gids on NETLINK_CB from a process in one user namespace to a process in another user namespace can result in the wrong uid or gid being presented to userspace. Avoid that problem by passing kuids and kgids instead. - define struct scm_creds for use in scm_cookie and netlink_skb_parms that holds uid and gid information in kuid_t and kgid_t. - Modify scm_set_cred to fill out scm_creds by heand instead of using cred_to_ucred to fill out struct ucred. This conversion ensures userspace does not get incorrect uid or gid values to look at. - Modify scm_recv to convert from struct scm_creds to struct ucred before copying credential values to userspace. - Modify __scm_send to populate struct scm_creds on in the scm_cookie, instead of just copying struct ucred from userspace. - Modify netlink_sendmsg to copy scm_creds instead of struct ucred into the NETLINK_CB.

It's the same problem that previous fix about blackhole and prohibit routes. When adding a throw route, it was handled like a classic route. Moreover, it was only possible to add this kind of routes by specifying an interface.

This reverts commit 5d65878d7031b6c39054b282faceff406bb2fda9. The upper layers call usbnet_start_xmit() with a valid skb. However cdc_ncm abuses this method by calling it with NULL to trigger IO for the aggregated private skb holding erlier packets. Until cdc_ncm is fixed, the check for NULL must be reintroduced.

Add support for genl "tcp_metrics". No locking is changed, only that now we can unlink and delete entries after grace period. We implement get/del for single entry and dump to support show/flush filtering in user space. Del without address attribute causes flush for all addresses, sadly under genl_mutex. v2: - remove rcu_assign_pointer as suggested by Eric Dumazet, it is not needed because there are no other writes under lock - move the flushing code in tcp_metrics_flush_all v3: - remove synchronize_rcu on flush as suggested by Eric Dumazet Signed-off-by:
