This patch corrects the SPDX License Identifier style in header files related to PHY Layer for Ethernet drivers. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used). This patch also gives an explicit block comment to the SPDX License Identifier. Changes made by using a script provided by Joe Perches here: https://lkml.org/lkml/2019/2/7/46. Suggested-by:

Commit 6570bc79 ("net: core: use listified Rx for GRO_NORMAL in napi_gro_receive()") has applied batched GRO_NORMAL packets processing to all napi_gro_receive() users, including mac80211-based drivers. However, this change has led to a regression in iwlwifi driver [1][2] as it is required for NAPI users to call napi_complete_done() or napi_complete() and the end of every polling iteration, whilst iwlwifi doesn't use NAPI scheduling at all and just calls napi_gro_flush(). In that particular case, packets which have not been already flushed from napi->rx_list stall in it until at least next Rx cycle. Fix this by adding a manual flushing of the list to iwlwifi driver right before napi_gro_flush() call to mimic napi_complete() logics. I prefer to open-code gro_normal_list() rather than exporting it for 2 reasons: * to prevent from using it and napi_gro_flush() in any new drivers, as it is the *really* bad way to use NAPI that should be avoided; * to keep gro_normal_list() static and don't lose any CC optimizations. I also don't add the "Fixes:" tag as the mentioned commit was only a trigger that only exposed an improper usage of NAPI in this particular driver.

The timestamp ID is only from 0 to 3 while the FIFO supports 128 timestamps at most. - Convert to use skb queue instead of the list of skbs to provide protect with lock.

In gve_alloc_queue_page_list(), when a page allocation fails, qpl->num_entries will be wrong. In this case priv->num_registered_pages can underflow in gve_free_queue_page_list(), causing subsequent calls to gve_alloc_queue_page_list() to fail.

When user-space sets the OVS_UFID_F_OMIT_* flags, and the relevant flow has no UFID, we can exceed the computed size, as ovs_nla_put_identifier() will always dump an OVS_FLOW_ATTR_KEY attribute.

We need to calculate the skb size correctly otherwise we risk triggering skb_over_panic[1]. The issue is that data_len is added to the skb in a nl attribute, but we don't account for its header size (nlattr 4 bytes) and alignment. We account for it when calculating the total size in the > PSAMPLE_MAX_PACKET_SIZE comparison correctly, but not when allocating after that. The fix is simple - use nla_total_size() for data_len when allocating. To reproduce: $ tc qdisc add dev eth1 clsact $ tc filter add dev eth1 egress matchall action sample rate 1 group 1 trunc 129 $ mausezahn eth1 -b bcast -a rand -c 1 -p 129 < skb_over_panic BUG(), tail is 4 bytes past skb->end > [1] Trace: [ 50.459526][ T3480] skbuff: skb_over_panic: text:(____ptrval____) len:196 put:136 head:(____ptrval____) data:(____ptrval____) tail:0xc4 end:0xc0 dev:<NULL> [ 50.474339][ T3480] ------------[ cut here ]------------ [ 50.481132][ T3480] kernel BUG at net/core/skbuff.c:108!

Note that the sysctl write accessor functions guarantee that: net->ipv4.sysctl_ip_prot_sock <= net->ipv4.ip_local_ports.range[0] invariant is maintained, and as such the max() in selinux hooks is actually spurious. ie. even though if (snum < max(inet_prot_sock(sock_net(sk)), low) || snum > high) { per logic is the same as if ((snum < inet_prot_sock(sock_net(sk)) && snum < low) || snum > high) { it is actually functionally equivalent to: if (snum < low || snum > high) { which is equivalent to: if (snum < inet_prot_sock(sock_net(sk)) || snum < low || snum > high) { even though the first clause is spurious. But we want to hold on to it in case we ever want to change what what inet_port_requires_bind_service() means (for example by changing it from a, by default, [0..1024) range to some sort of set).

Thomas Falcon says: ==================== ibmvnic: Harden device commands and queries This patch series fixes some shortcomings with the current VNIC device command implementation. The first patch fixes the initialization of driver completion structures used for device commands. Additionally, all waits for device commands are bounded with a timeout in the event that the device does not respond or becomes inoperable. Finally, serialize queries to retain the integrity of device return codes. Changes in v2: - included header comment for ibmvnic_wait_for_completion - removed open-coded loop in patch 3/4, suggested by Jakub - ibmvnic_wait_for_completion accepts timeout value in milliseconds instead of jiffies - timeout calculations cleaned up and completed before wait loop - included missing mutex_destroy calls, suggested by Jakub - included comment before mutex declaration ==================== Signed-off-by:

Pull thread management updates from Christian Brauner: - A pidfd's fdinfo file currently contains the field "Pid:\t<pid>" where <pid> is the pid of the process in the pid namespace of the procfs instance the fdinfo file for the pidfd was opened in. The fdinfo file has now gained a new "NSpid:\t<ns-pid1>[\t<ns-pid2>[...]]" field which lists the pids of the process in all child pid namespaces provided the pid namespace of the procfs instance it is looked up under has an ancestoral relationship with the pid namespace of the process. If it does not 0 will be shown and no further pid namespaces will be listed. Tests included. (Christian Kellner) - If the process the pidfd references has already exited, print -1 for the Pid and NSpid fields in the pidfd's fdinfo file. Tests included. (me) - Add CLONE_CLEAR_SIGHAND. This lets callers clear all signal handler that are not SIG_DFL or SIG_IGN at process creation time. This originated as a feature request from glibc to improve performance and elimate races in their posix_spawn() implementation. Tests included. (me) - Add support for choosing a specific pid for a process with clone3(). This is the feature which was part of the thread update for v5.4 but after a discussion at LPC in Lisbon we decided to delay it for one more cycle in order to make the interface more generic. This has now done. It is now possible to choose a specific pid in a whole pid namespaces (sub)hierarchy instead of just one pid namespace. In order to choose a specific pid the caller must have CAP_SYS_ADMIN in all owning user namespaces of the target pid namespaces. Tests included. (Adrian Reber) - Test improvements and extensions.
